Yeah but will you be able to drive upside down once all this is done?

Re: the 951 bellhousing - I guess everything has a price! But I am assuming Eric is more than skilled enough to tackle the clutch since he did the conversion in the first place.

Cool car my friend!

lol - i'm hoping that is not the result - i've nearly had that happen before as a result of somebody's bad underbody work - getting airborne at over 100mph is not nearly as much fun as it seems in the movies

Eric K: NICE JOB!

Three questions.

Did you stick with stock clutch plate? I am planning to use a stock S2 flywheel with centerforce dual friction disc and 'centerforce' PP.

Did you manufacture the post -intercooler air deflector?

What size intercooler (stock 951?)

This is a great thread!

Eric et al.,

I am guessing, just assuming, that the turbocharged 2.5 motor as you have set it up will require much more time and money to maintain than the 3.0 968 motor. I have not owned a 944 turbo, but I have heard that to service the engine, it takes more time and effort just to get past the layer of the turbo and all the extra piping and such that comes with it.

If you or anyone else who has owned both for comparison can comment, I for one would love to hear your experiences.

Thanks.

That's the easiest way to pull the drivine.

No, it is a turboRS replica piece from Fitzgerald racing in Australia.

The turbo will be more maintenance intensive. That is just the nature of it. There is a lot more plumbing and heat. Plus, Porsche engineered the 951 so you need to remove 3 things to get the part you are after. I've simplified as much as I could by removing all the HVAC, stock boost control, etc and there are still pipes and tubes everywhere!

Eric,

Thats what I reckoned... No free lunch. More power=more stuff+more things to service.

Can a person do what you did and keep the a/c?

The car now has a 2.5liter turbo engine from a 1989 Porsche 944 turbo in it. It is a fairly straight forward swap but of course the devil is in the details (and there are a lot of details). I bought the 951 parts car about six years ago with the intention of doing the swap and it has just now come to fruition. I was slowed down because as it turns out the 968 engine is a workhorse. It never let me down in 6 years of racing. It is now on the stand enjoying some time off.

Some how the random boxes of parts strewn across the garage reformed into an engine and it actually works! Quite well really. I have not tapped the engine's full potential (and may never) but on converative boost and crappy tires I lowered my best time at Spokane by nearly 5 seconds! It can outrun a mean e46 M3 on the straight - unfortunately he had me covered everywhere else that weekend but nothing a new set of tires and some fine tuning couldn't fix though.

I have a neighbour team with their 968 engine in pieces. The engines are hard to source here and rather a lot of money. What made you go the Turbo track rather than the V8 conversions that are common in the US for more power?

Just too much of a purist, I guess. [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img] I always liked to the TurboS/RS so I wanted to make something like it. The turbo swap might be a little more straight forward than the V8 conversion. But, having reliable V8 power sounds pretty good too.

Yes, Turbo RS is cool! [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img] Do you know of anyone racing reliably with a V8?

No, I don't know anybody with one in a Porsche but there are several race cars locally that use GM LS engines to good effect.

Eric,

Sorry I've missed your post until now!

I recently removed my 3 liter motor and also went with the 2.5...I love it!

It seems to spool up quicker, probably because of the shorter stroke.

I did this because in NASA it allows me to move down to GTS3 and in PCA it will also allow me to move downwards...to GT3S.

With NASA I also had to add 25 lbs to the car, so I now weigh in at around 2,850 lbs.

Good luck!

Jason

Any feeling of lag? Compared to staying with a naturally aspired engine?

Sounds like a smart move Jason. You will have better competition.


A lot depends on the setup being used, but lag is not really noticable on track because the revs never drop too far. If you bog the engine then yes you will feel it.
