TurboCab

At least theoretically, a turbocharger can be damaged if it is not sized correctly. If the turbo operates beyond the Surge line (turbocharger map) for a long time, it will break for sure. Surge is a very destructive event in which air slam back the compressor impeller in the oposite direction. Just my 2 cents about.

Rick, that is great customer service!

I think the turbo here made enough power upto 5500rpm. It would be safe to assume it is only slightly smaller than it needs to be on teh hotside. But I see what you are saying. A K26/6 will not last too long on my car either.

I saw Jason's car when it was near completion up on the lift at Rick's shop... stunning, to say the least.

I also checked out the motor while it was being built...also very very nice.

Rick does great work.

Let me know what you think....

BruceWard

Rick, I think that is amazing. I love the look of the conversion!

Can you tell us more about the intercooler?

RajDatta

Yeah, its a stock 951 piece Bruce.

Perhaps I misnamed the part. In this picture, what is the thing at the front and where did it come from?

TurboCab

Are those the new Mahle 968 Turbo pistons?

Rick DeMan

Hi All,

That piece behind the intercooler is a copy of the 968 Factory turbo intercooler duct...it directs the hot air out the opening in the hood...

Yes, those are Mahle turbo pistons for the 2 valve head made to go in the Alusil bore of the 968 block.....

Reeaalllllyyyy.....what's the URL?

Sorry, couldn't help myself.

Rick, quick question. Why cheap out on the wastegate? The factory wastegate is a total piece of crap and bleeds boost from 4psi on. Why not go with a better or a dual port wastegate and take full advantage of the motor?
BTW, looks very similar to my setup .

Raj,

Cheap out??? Piece of crap???

Go to the back of the classroom....and remember what my mom said "if you don't have anything nice to say say nothing at all..."

RajDatta

Rick, I am not questioning your knowledge and I hope you don't take it like that but its a known problem with stock wastegates. They bleed off boost. I know you do this for a living but an open mind is not a bad thing.
I will be more than glad to go to the back of the room if you prove me wrong. You asked for opinions and I gave you mine. I didn't know the opinions were only supposed to be positive. Sorry for sharing my opinion.
