Hello,

I have a 1995 993 RS Clubsport and would like to upgrade the power of the car. One option is to source and install a 993 turbo engine. Having now found one I am wondering if it is possible to fit this engine from a 1997 993 turbo which has the standard 408 bhp.

I am so far only aware of the need to change to a GT2 style rear spoiler. What other modifications are needed? Will my RS G50/32 gearbox fit to the Trubo engine and can it handle the power and the torque of the std. engine. What are the power/torque tollerances of the standard g50/32 gearbox.

The engine is "turnkey" including all ancillaries such as wiring loom etc.

All input is most welcome.

Thank you

Jean

Jonas, yes you can and I think it is the best bang for the buck for anyone wanting to get more power from his N/A car. It will take some work but nothing that an experienced mechanic cannot do. Make sure you get the wiring harness and ECU with it, it will make your life easier I am told.

With the weight of your car and a stock TT motor, your car will be extremely fast.

Your stock G50/32 can withstand perfectly well the torque of the stock TT engine, it is a straightforward bolt-on, you will need a clutch change though.

More technically experienced guys will chime in hopefully.

Jonas, if you do this I'd love a ride! Your car will be seriously fast.

Jean,
Thanks for the input. A Swedish friend of mine Magnus told me to seek input from you. Once again thanks. My car now weighs 1200 kg with the original doors which are planned to be replaced with similar plastic items but it seems difficult to find them here in Sweden and Cargraphics are simply are ripoff at €2500+.
Question:
1. What do you see as a fair value for a low mileage [<10000 miles] stock engine with all ancilliaries included?
2. Are there any changes in the engine this being a Euro 1997 car/engine. [I know updates to the gearbox where made in 1997 as an example].
3. Would you recommend using a secondary oil cooler with the standard 408 engine?

Thanks for you replies so far.

Jean

Jonas, any friend of Magnus is a great friend of ours here

I am not a mechanic or tuner or anywhere close to being one, so whatever I tell you needs to be verified by the people in the know.

For the doors, try DP Motorsports in Germany, they have fantastic stuff, or for the real stuff, you cantry Gert, at www.carnewal.com but expect to pay the price for great the quality stuff he sells.

1- I sold sometime back a full FVD engine with 540HP upgrade including Cargraphic intercooler, ECU, etc.. for 25K USD, you should get a stock engine with low mileage for around 20k USD Max. if you wait and look closely, don't go to the famous dismantlers
2- No changes to the engine, maybe some minor stuff, the ECU was changed but nothing to worry about. The gearbox update in 1997 was a stronger mainshaft "it seems", but nothing to write home about, they still bend if you launch hard.
3- I would not anticipate the need for an extra oil cooler ( it is Sweden afterall! ) for a stock engine, but you can wait and see once you run the car.

Others might have different opinions
Keep us posted and feel free to ask any questions.
Cheers

Hi Jonas,
perhaps a silly question but why don't you just carry out a twin turbo conversion to your motor ?. Or is the 993 TT motor that cheap ?. You are in the write part of the world so talk to Micke Svens. Here is his link.

I have a 993TT in a 964!

If you are goin to do this...seriously think about doing it with a 996TT...much better starting spot for mods...and IT CAN BE DONE!

TomF

What a ba$tard child that would be- a 996TT water-pumper in the pinnacle of Porsche air-cooled engineering, the 993 RS?! That hurt me just to type. Oh the humanity! Please tell me that you were joking...

Jonas Ribbelov

No I will stick with an aircooled engine in the car as Porsche intended. If I was going down the watercooled alley it would be to fit a GT3 RS engine....

The 993TT alternative is too an easy alternative not to pursue it...

Can't wait, question is what I will call it GT2 RS

No I think I will stick with the iconic 993 RS. Mind you so far I don't like the look of the GT2 wing from behind the car. Here I think the standard Clubsport wing looks better. This might change though....

You need to start em early, a picture of my daughter learning to drive...

Rassel

That's like asking Todd to go over your engine.
It will make a huge hole in the wallet and you'll have the fastest car on the continent. Going to these guys, I think you should really think twice. It's A class tuning and question is if you really need those last HP. If it was free, I wouldn't hesitate a second whom to go to! Micke is sure a great guy and a Porsche lover too.

How's that GT2 of yours doing? Still as adorable as ever?

Let's make it easy Jonas. I'll buy you a TT and you can pass the RSCS to me...

Hi Rassel,
for one reason or another it did not happen. Not something I wish to share. I'm still looking but the prices seem to be going up and up. Hopefully will have one soon, currently an evo on the near horizon. Spent yesterday at Silverstone on the GP circuit in between rain and shine with a real nice chap who let me loose in his 993 GT2 club sport. Awesome bit of kit which reassured me I was making the right decision.

clubsport1

9M, fabricate billet heads and various other mods to get 400bhp out of the n/a motor, have you considered this? More in keeping with the character of the original car?

Rassel

Even if it gives 380bhp it's tempting, though I'd do it on a spare engine and not the original RS 3.8

clubsport1

As an aside have you seen this RS conversion?

(Ignore the price it is slightly optimistic, this sold in Germany for substantially less last year.)
