OK - I already have 996tt tip and GT2 plus others. I am going to build a 996 turbo monster from scratch. eek: I need your valued experience in deciding the best base engine parts - block, crank, heads, oil pump etc. I will probably go for Carillo rods, standard 996tt pistons. I have access to original GT1 headers, K27/29 turbos with external wastegates and will probably run the thing on MoTeC. I already have some experience using MoTeC on my RS4 Audi. Also, what are the things needed to be done to the block, crank etc to cope with this kind of grunt?

 

How are GT1 headers different from OEM headers? Do you have any photos? Do they bolt right on to a 996TT? What are the benefits?

Thanks,

Craig

 

I would recommend these.

I don't believe even Ruf would recommend their titanium steel rods for 900 hp.

 

Certainly a great project. Good luck with it.
Are you planning on doing it yourself or basing most of it off of a particular tuner? Also are you looking for 900 whp or at the flywheel? EVOMS has produced a car that dynoed at over 800 to the wheels but it blew its clutch too quick for any good testing. Does anyone know what became of this car? Also, protomotive has done several cars in this range. Should be a fun project.

The reason I am looking at the GT1 headers is because they are designed to be used with the K27 turbo with external wastegates. ie. they have the additional header connection for the wastegate.

I know I can get Evoms or others to supply the tuning hardware and there are several options for the software but what I really need to know is what block, crank, heads etc are best to start with. I heard a 964 block was the same as 993, 996 etc. Is that true? I just want to start piecing together my hardware and get any necessary mods done to it such as shuffle pinning. Can someone explain what that involves?

 

Well you could read this little thread, it pretty much sums everything up for you. See you in a few years when you're through reading it

The car did not blow a clutch. It was a QC issue with Sachs. The pressure plate pins caught and would not release. The clutch remained engaged all the time. They have since corrected that issue. Trust me I was there and helped them install the new one on location. The car was built with all that in mind. EVO pulled all the stops and it was Sachs that created the issue.

K27s on a 996TT will not equal any fun. The amount of air it takes that turbo to spool will put the power band on a 996TT at about 5K RPM. Maybe higher. The GT1 made good power, but not in the street curve. It ran in a RPM range higher than our limits and normally did not come down from there. There are a lot better opinions out there to make power. That is not it.

 

Boy, I remember when the Stage IV cars were exciting to read about. Now that some of you folks are pushing 700, 800, and now 900hp, at what point will the insanity end!!

Isn't there a point at which the Fun Factor vs. reliability vs. cost sort of collides on a curve somewhere? Is this all akin to someone getting plastic surgery and then becoming a plastic surgery junkie until they look like Michael Jackson?

Sorry Porscha for not being able to help you. I wish you all the luck and I'm sure that some of these folks are technically savvy enough to help you. I'm just scratching my head wondering what a 900hp tt 6 cylinder car would perform like? Would it be manageable?

 

I have wondered that too with Vipers with 1200 hp what is the point? Seems like at some junction you lose the ability to really use that much power unless you are simply drag racing. I think my car has enough hp, there are other things I can do but I think I happy at 700 to 750 hp.

I can't imagine trying to launch a 1200 hp Viper! Lots of tire smoke!

 

I will choose a tuner for the motor but use other routes for the build of the car. I think 900 flywheel bhp should be a high enough target. It will be a lightweight car for road, track days, sprints and hillclimbs. I will be talking to EVOMS for help.

 

So what turbos do I need for this power in a stretable car? Would you use an internally wastegated K24 as a starting point and put a Garrett compressor into a remachined KKK compressor cover? Or what?

 

Hint,

Find a set of 993 GT2 hot side turbo's cicera 1995. Clean them up and polish and have HPC coat them. These are K24's, but alot different and larger than the current K24's. They are very hard to find. Mate them with a T04 with proper A/R and wheel.

That is about all I;m going to say.

 

Buddy,

Around August we'll demonstrate "the point" and it will be an all around Porsche.
