Title: Project Car: Mid engine V8 Polo
Post by: tim_hcsc on October 28, 2012, 12:08:40 AM
Nice project, Iv been following the thread for a while.

I have a 98 Polo and decided to put a V8 in it too but I put it in the middle making it rear wheel drive, I used a 4 door shell as it makes access to the engine really easy and leaves loads of room for twin turbos (if I need them)

I cut in A4 Quattro rear quarters and suspension so I could use the rear hubs with driveshafts and have bigger brakes and wheels, these are 17 inch GTi wheels and they fit just right. Im going to use the A4 front hubs and brakes to match.

Its a slow process but Im getting there :D

Wow.
What V8 are you using?
I like the rear cut for the mechanical side tho it is looking a little fugly so far.

Im in Whangaparaoa just north of Auckland, I have a garage where I specialise in VW and Audi hence sticking the two of them together.

This is what the floor looks like when you cut it out  ;D

I added a main beam to strenghten the floor and build the rear end from, I used a Trammel gauge borrowed from the body shop next door to make sure everything is square, if I mess this bit up everything else will be out of line.

Are the black arms with bushes the A4 rear subframe?
Have you added engine mount points to them?

The engine is a 4.2 V8 taken from a 98 A8 and coupled to an A6, V6, 5 speed tiptronic box.
I have added a whole rear subframe and suspension from a A4 Quattro which will have to be cut in the middle to accept the transmission, the heavy bracing is to hold the suspension tops as they would normally be supported bu the parcel shelf.
Before I cut the Quattro to pieces I made jigs for the suspension so that I could re align everything more easily.
I have made a cradle for the engine that bolts to the new chassis rails so that the engine and box can easily be dropped out of the bottom of the car.
If the bracing looks too ugly when it gets further down the track I can always cut it out and make something lighter.

Its probably going to get a whole lot uglier before it starts to look like a car again.

It should be a lot of fun, I figured with a mid engine and rear wheel drive the weight distribution should be about right for great cornering and the engine height is low enough that its below window line so it cant be seen too easily, I will just box it in and it should be quiet too.

Here is the rear end all boxed in with regulation 100 x 50 so it will pass its cert as a scratch built.

Id like it to be finished tomorrow but the wife says work comes first, I also have to finish my project motorcycle which a turbocharged Kawasaki Z1300 (6 cylinder) built as a streetfighter.

Realistically about another 6 months

You on a suicide mission with that bike? Ive seen a few turboed bikes on Youtube  and they are just too much. >:D

Very glad to see your project as we had heard of it in the grapevine

As the advocate for such foolishness I can really appreciate the extent of what you are attempting.

I hope you find your way through the endless complexities

Cheers

Very similar thoughts i had been thinking about.
Is there any reason why you didnt use the front subframe out of an A4 mounted in the rear, then your engine mounts may have been easier using the A4 drive shafts as well..

Second question, is the V6 out os a S4 heavier tha the V8 you are using,no doubt you have thought of all options.

Title: Re: Project Car: Mid engine V8 Polo
Post by: qta4 on October 29, 2012, 07:00:51 PM
I would done an auto as well, due to the distance from the rear wheels to the back of the car, manual boxes would have extended beyond the body.

How do you figure that? the manual is the same size as the auto, maybe be smaller and certainly lighter

I happened to have an A4 quattro which was smashed to pieces, the right hand "A" post was only 6 inches from the centre console so everything at the front was pretty much toast, steering, suspension, subframe, all scrap so I used the rear end.
I figured the rear suspension would be more stable at the rear afterall thats where it was designed to be also the brakes are smaller than the front and has a hand brake type caliper.

I chose the auto because its tiptronic and I can always make it to paddle shift if I want a bit of fun or just leave it in auto for the dreaded  Auckland traffic. The drive shafts run at an angle of 6 degrees backwards from the diff so they are approaching the maximum angle  they can run at, apparently 7-8 is the max for safe operation. I guess I'll be the first to find out if there is a problem.

Its only a MK1 version and if I like it I can build a MK11 and change all the bits I didnt like in the first one

Sorry for the lack of updates, Im just in the process of trying out a Nissan Skyline rear sub frame in the car. Its a much more compact subframe with upper and lower wishbones attached to it plus I can narrow it to move the wheels back in closer to where they should be.
Hopefully some pictures soon.

I'm curious as to what happened to the mid engine Polo

Does anyone know if this was ever completed?
