Now that looks interesting Lee, ia that an audi V8 trying to mate with a VW polo.
Looks like you like working things out in very tight enclosures

Title: Re: Polo transplant
Post by: Lee on April 22, 2009, 09:26:02 PM
Yep--

4.2 litre  mated to a vr6 box .

Have worked it to be lighter on the front than the 1.8t with all its pumbing.

And yes its tight--

As a daily driver it should be ok

At first i thought Lee was just taking the piss, but now i realise he is serious, and knowing quiet Lee, he will have done lots of research before posting this up.
His technical ability is realy good.

Looking forward to seeing this thing being born.

Keep us all posted
Title: Re: Polo transplant
Post by: Lee on April 22, 2009, 09:58:25 PM
Thanks Noel,

Yes it's an interesting project.

Just for your info--the 1.8t conversion was good and I used it for 40 000 k

But you know how the incurable swapper mind works----------------hopeless

Anyway

The weight of the turbo engine + all gearbox etc etc =209 kg

The weight of the v8 is about the same but alittle tighter.

The battery and brake booster and windscreen water bottle is all going to the rear.

I hope it will be better mannered than the 1.8t

Will keep you posted

is it even going to fit behind the grill, let alone under the bonnet?

or will you have an even bigger hole than the twin VR6 Lupo?

crazy enough to be worth trying though,   ::)
Title: Re: Polo transplant
Post by: Lee on April 23, 2009, 08:11:20 AM
Hi Guys

In answer to the questions--

Will be using the same Link computer that ran the 1.8t
If anything it will be alot simpler

Re the size--No I don't like to show externally any difference than a standard car.
So no bulges --Its just a matter of modifying things until they fit.

Interesting that the motor and box fits sideways but is very wide--so it almost touches the firewall and the radiator,--this conversion would be easy in a golf or a3--
I don't know why others haven't tried it

Cheers

Post by: qta4 on April 23, 2009, 08:20:13 AM
The polo is an interesting cheap car, i have often toyed with the idea of fitting a V8 FWD assy in the rear .

But this has to be much more of a challenge, the alternator and PS pump will have to be really tight.

Anyway, good luck with this Lee.

Cheers Noel

Hi Lee, has using the offset bellhousing on the VR6 gearbox helped or would it be easier to use a 4 cylinder straight up housing. You could always swap to a 4 cylinder housing if you intend to fit a LSD
Title: Re: Polo transplant
Post by: qta4 on July 09, 2009, 07:13:13 PM
I sneaked over to Cambridge on Tuesday to look at Lee's progress.
It is certainly a complex job, but lee is making a great job.
His attention to detail is truly amazing, i also bet Lee goes to bed thinking about  little details every night.

I didn't take any photos, i will let lee show us when he is ready.

This car will look absolutely stock, no bulges any where, only problem at the moment is how to hold bonnet closed, as the catch which is in the middle front edge of bonnet is taken up by the cylinder head.

The radiator will be quite a compact assy, but amazingly the alternator and power steering pump fit easily, i cant say that about other bits though.

Truly amazing job Lee, well done.

Great stuff.
Title: Re: Polo transplant
Post by: Lee on July 21, 2009, 07:54:19 PM
This what was cut out of the passengers side front rail.

Because the car is just over 15 years old it does not have to be front impact compliant .

The rules are fairly stiff for later 95 cars onward.

My certifier here in the Waikato was quite happy with me cutting so much-- as the left rail only holds up the bumper it's not a major

Its tight on the right side but I didn't need to modify it

Title: Re: Polo transplant
Post by: Lee on July 21, 2009, 08:01:07 PM
Because the back of the v8 almost touches the bulkhead -the brake servo had to go.

Shown is a Nissan 25 mm master cylinder with pipe work to the rear remote servo .

Only the front brakes will be assisted.



Work in progress
Title: Re: Polo transplant

Title: Re: Polo transplant
Post by: Lee on July 21, 2009, 09:22:09 PM
You can see from this the front bank of cylinders.

My overall concern with this exercise is how front heavy the car will be.

I have reduced weight as much as possible and even had to delete the inlet manifold as it weighed 15 kg

Will be making a light weight aluminium manifold with short tracks instead of the original variable castings.

This will probably reduce the torque but I don't think power will be a problem.

Am working on the exhaust -oil external filter-brake lines -remote servo -battery relocation---

yeah --still working

Title: Re: Polo transplant
Post by: 80 Vert on July 21, 2009, 09:30:32 PM
Where are you putting the radiator Lee? When I saw you last I don't think you had decided?
Title: Re: Polo transplant
Post by: Lee on July 21, 2009, 10:00:31 PM
In front like normal.

It's slightly smaller than I would like and the fan may have to work more than normal.

With 4.2 litres it's not going to be under stress as the 1.8t was.

I have just had a major problem finding a crank angle sensor as the v8 ran it's sensor on the flexie plate. Ended up with a Nissan v8 sensor that I have to adapt to the end of the cam.


There are alot of things that will require modification but the main thing now is to get it running

Title: Re: Polo transplant
Post by: Lee on September 05, 2009, 06:53:24 PM
Yes lots of progress--

Inlet manifold is now finished--weighs 3 instead of the 15 kg of the original

I made a battery box for the rear for both battery and remote servo

Brake lines are all in--just need to bleed them

All the pipe work and radiator is now in and leak free--

Remote oil filter in now mounted

Crank angle sensor I finally found from a Nissan v8 --and I had to make a special thingame to mount it on the end of one of the cams

Oh yes a complete set of extractors ---

They say the devil is in the detail---Endless

However it should be ready to go for the computer to be re set and dynoed maybe next week   hmm  maybe

Will get some photos up soon

The computer had to be sent to Link in ChCh--but all going well it should be running next week

Actuality until it runs I have no idea as to how everything will work--there is so many decisions and assumptions in its building that it's a large leap in faith--quite nerveracking after all the time and energy

Thought I had better report in--

Well I got the car back from the computer wiring dept--with a few issues to modify.

Oil lines are too small for the oil flow required and several of the injectors needed cleaning.

But I started it this morning and ran it at idle .

Interesting its very very smooth and very quiet--quite suprising.

Should fix the oil lines next week --and then it can be driven at long last.

Also playing with 4 pot wilwoods to replace the standard front calipers--hope to delete another 10 kg from the front.

work still in progress---Will paste some pics next week

with that power/torque to weight ratio, a rear mounted turbo sounds like a recipe for

Post by: Lee on December 11, 2009, 07:21:37 PM
Well I drove it today----

First impressions are as expected.

Yes it's front heavy but doesn't feel any worse than when the car had the 1.8t

It's very smooth and quiet  and although it's not tuned properly it accelerates ok

A few issues of course;;

The clutch slave cyl is not  disengaging properly so I have a problem

Does anyone know if the slave on the gearbox is different between the O2J box and the O2A VR6 box

Is it possible that the slave just doesn't have the travel to disengage

Would appreciate your advice

Apart from a few oil leaks and the winwood calipers hitting the rims under braking- all OK

Still work in progress

Title: Re: Polo transplant
Post by: qta4 on December 11, 2009, 08:50:52 PM
Interesting question Lee, just look at what you are using and what is different from factory.

You have Audi A8 engine, Vw Polo master cylinder and Vr6 gearbox, with Vr6 slave cylinder.


Your Audi A8 clutch has a clutch length, the VR6 has also a stroke, and the Polo master cylinder can push so much.

So which part is the miss match?

I personally doubt the slave cylinder is the problem, so the OEM Polo master cylinder is probably the problem.

With my car, i had a std Mk1 golf and a 02A gearbox, using a mechanical clutch assy.

I found that the stroke of the std Mk1 system stroked 80mm and the 02A gearbox is 50mm, so i used a reduction stroke ratio to overcome the problem.

So, i am guessing that the problem probably is with your clutch master cylinder assy.

Title: Re: Polo transplant
Post by: 80 Vert on December 11, 2009, 09:05:08 PM
I would second that if indeed you are using Polo clutch master.
Title: Re: Polo transplant
Post by: Lee on December 11, 2009, 09:27:49 PM
No the polo has a mechanical clutch cable.

I used a hydraulic master off a golf 1.8t

It worked with the turbo motor and I haven't changed anything other than the Vr6 clutch

It worked with the dual mass clutch of the turbo

Just wondered if the gearbox's were different??

I used a hydraulic master off a golf 1.8t



Bit of a conflict here?

So you cant get it into gear?  I would try a few starts with it in gear and foot on clutch. If it starts and isnt trying to drive forward to hard it may just be a bit of wearing in to do.

Cars arunning!!

Still curing oil leaks and other teething problems but it drives OK

However because of the small size of the radiator due to space constraints,
I need to put on 2 more small cooling fans. Unfortunately the body work below the bumper doesn't give me enough room.

Jamie at Platinum tells me that the 1999 Polo has a one piece bumper/spoiler that may do the trick.

Does anyone have a secondhand one I can try?? Condition immaterial

Cheers

Don't know what type of driving you have done so far Lee but once you can just sit in traffic on a hot day and it doesn't overheat thats when the cooling system is sorted.

I doubt water wetter will be the complete answer to your problem, bigger radiator and/or more cooling fans will be the ticket I'd say.
How about a larger tank? more coolant in the system will also help but a bigger rad will be the most effective.

Just a small update--

The cars going well and yes lots of torque steer

I just had the car weighed and was quite pleased with the out come of my weight saving efforts

Car as 1.8t--- 1020 kg with 670 kg on the front wheels

Car as 4.2 V8--1030 kg with 680 kg over the front wheels

What were your problems Lee?
Title: Re: Polo transplant
Post by: Lee on April 14, 2010, 06:56:33 PM
The problems related to the combined  Nissan crank angle and cam angle sensor running off the cam.

Link in CH CH had to modify the computer to stop misfiring.

The plugs were firing but not necessarily when they should have.

There was a possibility of destroying the motor--

So the shop had it for over a month and were pleased to see me take it away.


It's interesting that although the car has high power and light weight ,it's nothing spectacular.

Driving back to my workshop I was wondering how to give it some real power--yeah right

It would not hurt your car and I bet you would find it fun and it would be great to see some numbers.
I think it would be a little hard to get away even though you have good front end weight but would pull very hard at the end.

Your just old school and don't like changing down around corners eh Lee :laugh:

Small update.

It runs----------------

Still a lot of work to do yet-- but I'm getting there.

Small technical problem I would appreciate some opinion on--

As you are aware the intake system is --throttle body--supercharger--intercooler--intake to engine

I have also installed a Forge type vacuum operated bypass valve after the throttle body with a 25mm pipe to the main manifold.

In theory-- at idle or cruise the bypass should be open and air should be bypassing the blower.

So the problem--

The motor starts and idles at 3k rpm but when the vacuum line is pulled from the bypass valve the revs drop.the vacuum line is sucking air.

When I block and unblock the pipe the revs rise and fall just like operating the throttle-- I have checked for air leaks but have found none.

Any thoughts as to what is happening??



Title: Re: Polo 4.2 V8 Transplant
Post by: 80 Vert on September 20, 2012, 08:38:35 PM
Bypass valve should be before throttlebody
Title: Re: Polo 4.2 V8 Transplant
Post by: Lee on September 20, 2012, 08:50:25 PM
The throttle controls the amount of air introduced into the engine---as I understand it you cannot bypass in or out before the throttle body.



Title: Re: Polo 4.2 V8 Transplant
Post by: 80 Vert on September 20, 2012, 09:11:18 PM
All turbo and S/C cars have bypass valve before throttle body not after.
Title: Polo 4.2 V8 Transplant
Post by: ritmo on September 20, 2012, 09:20:21 PM
Are you sure Vert? Bypass by its very
Nature is suppose to let air in when TB is closed. So has to be plenum side.
Title: Re: Polo 4.2 V8 Transplant
Post by: 00quattro00 on September 20, 2012, 09:23:35 PM
When you close the throttle it dumps the air between the throttle body and engine back infront of the throttle body
Title: Re: Polo 4.2 V8 Transplant
Post by: 80 Vert on September 20, 2012, 09:28:01 PM
We are talking about a bypass valve as in blow off valve yes?
If so then when the throttle snaps shut vacuum is created which opens the valve to bypass air back to the inlet side of the turbo or S/C.
This valve is always before the throttle body, have never seen it any other way.

Edit, just seen your set up is different........
Title: Polo 4.2 V8 Transplant
Post by: ritmo on September 20, 2012, 10:04:36 PM
Ok bit of confusion here... I was thinking idle control valve as opposed to blow off valve. Which bypasses TB.
Title: Re: Polo 4.2 V8 Transplant
Post by: mark2 golf on September 21, 2012, 07:33:53 AM
Johns right it should be in front of the TB. It will be very hard to get idle control with it there. Are you running a Air flow meter?
Title: Re: Polo 4.2 V8 Transplant
Post by: Lee on September 21, 2012, 07:55:06 AM
The Link computer uses data from throttle position and air mass from within the manifold --

so no there is nothing before the throttle body other than the air cleaner.
Title: Re: Polo 4.2 V8 Transplant
Post by: 5-pot on September 21, 2012, 11:02:33 AM
The bypass valve should be introducing an air circuit from the TB straight to the intake, removing the blower and intercooler from the circuit.

The TB still has to meter the air going to the valve/intake so, the bypass needs to be after the TB right? 

So, it should kinda sound like Throttle body - bypass intake - blower - intercooler - bypass outlet - intake manifold.

That's my 2c's worth

I don't think we're talking about a blow-off-valve here.

He wants to bypass the blower at idle/cruise, not dump excess boost pressure in the intake tract.

Unless I'm thinking about this the wrong way.

Yes saw that and his comment about blow off compared to butterfly valve was interesting.

I was working on the car today and it runs but only at 4000rpm--this with the bypass valve wide open.

I cannot figure out why when the engine is running that if I pull the the vacuum line off the bypass the revs drop .

by putting my thumb on the v/line the engine can be reved as if the throttle has been opened.

Have I a air leak ??

Isn't your you bypass valve your air leak. Or am i missing something. It being open is effectively another throttle that's why its at 4000rpm

Just re read your original post and your set up is what I have on my 05 Mustang, air in through T/B, through S/C through intercooler into engine.
In theory you don't need a bypass valve as the throttle body doesn't see any boost at any time, its purely there the meter air going in.

I was thinking about having an external S/C or Turbo hence the need to bypass boost when T/B is closed which is why you'd need a valve.
Title: Re: Polo 4.2 V8 Transplant
Post by: M on September 23, 2012, 04:24:28 PM
I agree with John. If the tb is before SC what are you trying to bypass? When you close the throttle there is no air getting to the SC or engine so nothing to bypass?
Title: Re: Polo 4.2 V8 Transplant
Post by: BB on September 23, 2012, 05:48:46 PM
Two things.
1 is an idle valve. This you need when you have a complete air shut off system at the butterfly like an ABF engine.
The throttle closes and hits the idle switch which then opens the electronically controlled idle valve that takes air at a controlled amount straight from the intake snorkel before the air temp sensor, MAF and obviously the throttle body.
To do away with this system you have to close up all the intake holes where the idle valve was etc and make a stop that holds the butterfly open so as to allow enough air to idle.

2 is a blow off valve, which can only work if everything is before the throttle body so that the butterfly can close and block out the incoming boosted air and create a vacume in the manifold fast enough to allow a vacume valve in the intake system to be activated and vent that air out to the atmosphere WOOOSSSSHHHH.

Then I guess 3 which is a turbo wastegate which is a safety valve to stop too much boost even with the throttle wide open cause the air just can't take that much AIR man!
But that is not needed really on a SC car is it unless your maybe doing big high revs off throttle runs? But I think more of a idle switch SC bypass would be used.


I think what is happening is that you might be just getting too much boost from thee SC even at idle and you need to bypass the SC at idle?
My thoughts anyway :P

Small update

Solved my 4k idling problem--turned out to be 0 rings in the intercooler not seating properly creating air leaks--

Have driven the car a couple of times now-- but the blower seals blew and oil went everywhere.

So the blower is off  and about to get new bearings and seals.

The 3" exhaust is a very loud problem and have Andy helping with a couple of options to keep it below 95db for the cert.

Good things are the excellent clutch and gearbox--they were total unknowns. Gearing is 100k in 5th @ 2000rpm

The motor too is excellent --as well as it should be with 90k on it

Otherwise not much to report --it should be back on the road soon



Title: Re: Polo 4.2 V8 Transplant
Post by: Lee on October 21, 2012, 08:48:18 PM
Well the new bearings and seals went into the Sprintex and today I put it all back on the motor.

Started it up and it idles nicely--very pleasing indeed

Once I cure the loud exhaust  it will go for cert and then dyno tuning.

So not too far off being my daily again

This new engine, adapter plate, another  gearbox and the  Hydroboost braking has taken alot more time than I expected.

It's been 6 months in the oven

Hey guys

Haven't posted much lately but thought you might be interested in the next Polo V8 incarnation

The last supercharged implant was not a success as the blower blew up and the the drive shaft hit one of the external oil filter feeds and cracked the block.

After a lot of stuffing round I ended up deciding the BFM motor was no longer applicable.

I happened upon a later S4 4.2 40v chain drive engine from euroline which was just basically spare parts.

The engine was rebuilt using missing parts from Wolf auto parts in America----

So this new engine BBK is lighter and smaller than the BFM and fits the Polo engine bay with room to spare.

As it has variable cams I was not able to use the Link computer that has powered so many Polo incarnations

I decided to go mega squirt as the complete deal was half the price of the newer Links that were needed for the cams

So today it is all running and ready for a WOF after a long long rebuild

Title: Re: Polo 4.2 V8 Transplant
Post by: Lee on September 19, 2014, 06:39:06 PM
The newer Link was too expensive when you add everything including final tuning compared to megasquirt $1300.00 for ECU -4 coils -crank angle wheel and sensor inc gst . Very easy to install even for a non electronics guy like me.

Been dealing with Jared from http://www.megasquirtnz.co.nz/ and he has been most helpful and very tolerent .

With the big bore exhaust and megasquirt I can expect the 360 horses that the stock engine produces maybe more.

I will take it to Jared in Tauranga for final dyno tuning in a week or two...

Will try to get some pics up

And what flywheel with clutch are you using?

Hey

It is now seven years since I was working this project and it  has been since sold to a guy in Dunedin who is further developing it as a road car.

but  to answer your question the flywheel and clutch is just  standard VR6.

The adaptor  plate was just hand made.

Cheers
Title: Re: Polo 4.2 V8 Transplant
Post by: polo 3 on March 19, 2022, 12:02:14 AM
Thanks for the reply.
Does the original flywheel fit in one go on the V8 crank?
Or does it need modifications?

I can see there are adapters for sale to mount a VR6 engine on to the Audi gearbox, but not the other way around.

Can i ask how you made it, and how did you manage to align the gearbox main shaft to the center of the engine crank?
And was it 2 cm steel, or alloy?

Thanks again for your reply.

Title: Re: Polo 4.2 V8 Transplant
Post by: Lee on March 19, 2022, 10:18:34 AM
If I remember correctly yes the VR6 flywheel will just bolt on.
As I used a Golf diesel 5 speed box the starter motor fits fine, although the flywheel needed to be packed out slightly.
To make the adapter plate was just making a paper out line of  surfaces and cutting out it out of 10mm steel.
The key to getting them aligned is turning up a plug that inserts into the crankshaft and slides over the gearbox shaft.
Also with the V8 there is little room for the driveshaft gearbox flange and I had to use a smaller dia CV.
It is possible
Title: Re: Polo 4.2 V8 Transplant
Post by: polo 3 on March 19, 2022, 08:58:01 PM
Okay, so you used a Golf 4 diesel gearbox?
Or a Golf 3 VR6 gearbox with the diesel starter motor?

You had to shimm the flywheel a little on the crankshaft to stick it out far enough to make the starter motor work?

So on the right side of the gearbox you used a smaller flange with cv, do you still know from what car that was?

How did it drive when it was ready?
Could the original shocks handle the weight, and would the nose turn correctly in corners?

I am thinking about building a front V8 mounted engine, or a mid mounted engine.

I am first looking for the best way to do it, it also needs to be safe and road legal.
