Going with replacement Mahle ones, looked at the LN Eng Nickies but can't justify the extra cost. 10K on pistons and liners is enough for me.
Should have a nice power and torque gain.

Finally made a start on the 964 today, the engine has been getting done in the background but the strip down of the body started today. Interior up first, I'll get some zip loc bags tomorrow and hopefully some plastic storage bins for the parts.
I'm tearing most of it apart for a full repaint and colour change.
Interior wise I'm wanting a change from the factory blue to umm, something else. I have a set of MK5 Recaro buckets but a measure up of them today looks like they might be too wide to fit so as a back up my Recaro Pole position style full carbon seats are probably going in.

Time to get serious with this, sent the car out few weeks ago to have the rear lid gaps corrected as the back of the body was 5-7mm out of square. No evidence of a crash but from what I understand these are pretty weak in the back and simply sliding in to a kerb hard enough can cause this damage with the weight of the engine moving things around.
Gentle pull on chassis machine has everything fitting nicely again.
Cleared space for its return which has finally given me a nice carpeted area to work on stripping it completely for a colour change, not feeling the blue with blue interior.
It will be stripped pretty much to a shell and rebuilt from there up.

Since a repaint and colour change is first on the list I'm trying to decide on a colour.
The list so far is
Grand Prix white
Slate Grey metallic

Audi colours on Porsche... Might as well suggest Nogaro Blue.

But seriously, I think any of those options will be sharp on a 964.

Body now stripped apart from the underpinnings its time to address the panel fit issues. The doors and guards really don't fit that well, at least not good enough for me.
Each panel is stamped with a unique number matching the body number and all of mine except the engine lid match the car so I really don't understand it as there's no evidence of any crash damage to the body work.
Parts of it have been painted in the past but nothing seems to fit very well.
Spent some hours moving the doors around to a point where they look really good, the edge of the 1/4 and door roll in a lot so if you put a straight edge across there's a sizable gap to the body work at that point.
I decided to just block the area down with 120 grit paper effectively using the existing paint to block the thing straight.
Small amount of filler in the rear 1/4 which mostly all wasn't needed.
Front guards have never been off but the RH front cowl has a crack on the edge, another one of those strange things but to repair it the fender needs coming off.
Fender removed there's very minor surface rust to deal with, ill probably remove the other one as well to check that side too.

Finally got the 964 out of where it was stored to get on with the dirty part of the works. Good to have it in the work shop to get on with panel fit and repairing a couple of small rust spots in the window frame.
Remind me again why I keep fixing all this old crap?

Once I started grinding on the rust it became a hole and kept growing...with the rust ground away I just made a patch and welded in which then was metal finished ready for epoxy primer.
Quite an odd spot for rust, most probably started as a rock chip and spread from there.

The cowl had a large split right on the edge which was the main reason for removing the fender. Fender had never been off before and no damage in the front end so can only assume metal fatigue causing this, quite odd.
Anyway its just a simple case of welding the crack back up and grinding it back.
Getting the gaps dialled in now before it heads off for paint, was going to paint it myself as I normally would but I just can't be bothered with this one as its just going to take too long and I have the Mk2 Golf to paint as well.

Bodywork, really don't enjoy it but needs must. Have spent the last few days block sanding and playing around with panel fit on the doors and guards.
The right front guard had to come off to sort out a gap issue to the door and kind of fortunate as I found some rust that was actually worse than it looked.
Cut that area out and made a patch to weld in, some surface rust on the fender to body edge to be removed and treated before some epoxy was applied.

The rest is just boring block sanding using the old paint on it to block it straight with 150 grit.
Most of it looks pretty good, a few areas to attend to like the rear 1/4 to the door which will need a little filler to have really straight sides to achieve what I want.
Full colour change to Slate Grey Metallic has made this old bucket of bolts a much bigger job than what it was going to be but that's how it goes.

Getting closer to body shop and paint, only a couple weeks to left. Started looking at all the unbolted parts to be painted and the later aero mirrors I sourced are both different colours so the only correct way to paint them is to separate the bases from the housings.
Made a very crude quick little tool to tension the spring to allow them to be twisted apart.
This will prove its worth more at reassembly to be able to do it in a controlled manner without buggering up the new paint.
Paid dearly for my laziness not putting the car on the lift to strip the engine bay, groveling around on the floor in the blazing heat was no fun.
The body is looking pretty good, great gaps now and panels fit well. Door hinge pins are loose so that hinges do not need to be unbolted again.
Once primed for the final block before paint I'll get it back to strip all of the running gear out and paint it underneath which I'll do here, then let a pro paint the outside.
