munched engine...ouch! not for the faint of heart

[ArthurPE]

go to Porsches website

I think instead of posting as many swear words you should have spent a bit longer to check your sources and double check the fact that Porsche do NOT use DI on any GT engine, be it GT2, GT3, GT3RS, or GT2RS. Only the 997TT and the Carreras get it, as well as the Caymans/Boxsters and Cayennes, but NO GT2/3 engine has DI as of yet.

really?

now
check out their wesite

Since when has a 2008 article on Autoblog been a reliable source of information? Check out www.6speedonline.com where people have already taken brand new 3.8l GT3s and 997 GT2s apart, they both use the legendary GT1 engine still, not the japanese 9A1 DFI engine. The turbo and turbo S however do use DFI indeed. You can go on and call me a fool, but check your information more accurately, heck, you don't have any friends at Porsche NA?

that is technical
no, I will not share it with you
do your own research, I'll do mine...

it's true
many engines (RS4) HAVE been borescoped, in the US
and piston crown cokin is not an issue (any more than any other car)
I've talked to people who had it done
I've talked to a tech who DID it...
and confirmed by other sources

At the outset you said you wanted to keep this thread "technical". How do all the above statements fit into that? Serious question. Let's have more information please.

[ArthurPE]

AFAIK the Gen 2 997 GT3's have DFI, and most likely the 997 GT2 RS will also have it for that's the way it's going..

All prior GT2/GT3's did not.

I'm not sure...there is conflicting info out there...

In other words, we have no credible information. Thank you.

I thought 997 GT3's may have had DFI, but I don't think so.

No DFI on GT2/GT3's.

[ArthurPE]

The DFI engines haven't been regarded as "bulletproof" by Porsche yet for their GT cars, which keep their warranty even if something wrong was to happen on track...that tells a lot about the good ole Metzger GT1 engine

if they are not DI, that is not the reason...

it's economic
they are still using the old gen block as the basis and for the small production numbers not economically benefiicial to convert them to DI

when the GT2/3 get the new block, they will get DI
although I'm still not sure if the GT3 doesn't already have it


but the point is Porsche sells 100,000's of cars, 99% with DI

go to Porsches website...

Did not see mention of DFI on GT2/GT3.

[S2tuner]

Arthur, check your sources, heck, call a Porsche dealership and ask them, then you'll see

dig deeper

Maybe they have special engines for the US?

Gents - if you're going to have another private "tiff" please do it my PM.

I for one am getting sick and tired of this forum being filled with posts of your personal disagreements.

Here here, I'm very interested in the technical argument and resolution to this problem.......as far as this forum goes anyway

PD, there is no tiff as you want to see it. It's fact finding, and better understanding the issue. I have learnt something today about GT2/GT3 engines as has Arthur I suspect thanks to S2 Tuner.

Also means we must not have wrong or misleading data. ArthurPe will say when he wants to discuss it by PM, it's his thread.

It's discussions like this we found out that 14k RS4's were produced and not 30k. etc etc.
