Bens old turbo meets my 3l 8 valve project.

Oli, I am very impressed with the wooded transaxles you have in Finland, however they are not up to the quality standard of your other modified components.
We are still using aluminium

That wooden (plywood) version is very safe. It fits like a glove under 944 transmission. When you native country have more wood than most EU countries together it's quite natrural to use your local natural resources []

Here's another wooden special tool for 944's which was fabricated by my friend Harri

You definitely must lower the static compression ratio or you will suffer from detonation.

However the 968 pistons can be machined and take the right shape for that head and you can get 8.5 to one which is good enough for a std turbo providing 340 lbs feet torque and 300 bhp and a nice driveable car.

If you intend a bigger turbo I think you will need perhaps 7.5 to 0ne compression ratio and the 968 pistons will end up with too small a crown thickness - however I have a batch of special pistons in stock (for a number of future 3 litre rebuilds) for this purpose and have one set still available - if you are interested (contact me on baz@hartech.org).

We have just stripped down our 3 litre turbo (with the 2.7 head as featured in 911 & Porsche World recently) and everything is good - pistons show no strain, bores OK heads clean and no detonation.

I took it down to fit a bigger oil cooler (for track use) and to fit cylinder head sealing Wills rings - not because we had a problem but to enable more boost to follow reliably if anyone wants to do so after it is sold (it runs totally standard boost etc).

So your project seems very viable - but please don't fall into the trap of assuming high compression will work OK.

Not done much to the car due to the weather but it is now at my parents house as they have a double garage. So the project is back on track.
I replaced the front shocks and cut out the the rust on the front wings and welded wing bottoms in off of my old car. Just need to fit the brackets so the under body trim can be bolted on.

Below is one of the wing bottoms that didn't look too bad from the outside.

Not too sure what to do about the foglights as the lenses and the back plates are pretty much ruined. I'm toying with the Idea of getting clear lenses and fitting side lights in the indicators.
Oddly with no front fog bulbs the rears don't work so will take some fiddling. I was thinking of mounting the lamp guards but without the lamps and painting them, maybe with a vent fitted too. More weight/cash saving.
