If its any interest to you, I am in the process of turboing my 3.2 carrera. I have been heavily into vauxhalls for a number of years, I have owned and built some pretty quick ones my favourite being this one:
with this:
I bought my carrera 3.2 on impulse, didn't even give it the once over, just did the classic no no and fell in love with it. Please don't take this as a criticism but after playing for years with vauxhalls, there are many websites with alot of knowledge related to tuning, what will net you the best gains for little money etc etc. Yet in regards to the porche world, it seems very closed, I can find anywhere buy a decent 3.3 turbo engine/3.6 turbo, anywhere that does have one wants very silly money for them. As such, I'm in the process of turbocharging my 3.2 lump. Its VERY easy with anyone with some intelligence to modify the intermediate pipe to house the turbo charger, oil feed is pretty simple (next to the gauge sender) and return (to one of the oil cooler lines) I'm using a huge charge cooler (mounted where the back seats used to be) Autronic SM4 management with has launch control, GT35 R, run a seperate header tank and pump to water cool the turbo (behind the front bumper) The main expense are the barrels and pistons (not yet purchased) and the management. I hoping to build and map it for somewhere in the 6k region, which is what someone wanted me to pay for an 80,000 mile 3.3 turbo lump. I know alot of people will consider this sacrilage, (hey, its a 3.2 carrera with 965 body panels, 997 turbo 2's no interior trim and left to right hand drive converted), but the main point being its possible, and can make far more power, and more reliable than the ageing porche 3.3/3.6 turbo motor using the KKK series turbos and old motronic! (my autronic has launch control and traction control built in as standard, in theory I should be able to grace the rev limiter and sidestep the clutch and just go!) I have had absolutely no porsche specific input other than people saying... ohh that will never work! Its will, if you are reaosnably mechanically minded and you know the right places to look for things, you can do it you self, DIY turbo the car. Mines not finsihed yet (I'm in the process of grafting my new 965 rear 1/4s on,) but I will post some pictures of my progress soon.
cheers
