Most of you know what I have already, so what will it take to get 850 rwhp? I know I need to port and polish the heads and go to bigger turbos. GT35's? What about the 3.8 liter kit is that necessary or can I stick with the 3.6?

My internals are built I have upgraded fuel lines, will need bigger injectors and bigger fuel pump. What else? I have a stage 3 clutch and lwfw, what am I missing?

Any guesses as to what this will cost? Ideas are requested and appreciated help me build this car!

 

Evoms said to go gt800 is another 20k I couldn't believe it! To be honest I think that price is a slap in the face. that price includes trade in of parts. We don't even get to keep the 700 turbos and headers. Im going the custom route which should give me alot of power.

What are you planning? Who are you going to use?

 

gt30/k24 turbos, second fuel pump, 3.8 liter piston conversion. larger injectors, tune by EPlabs.net.

Good luck! Let us know how it turns out!

 

sticky - I want to know too. But I already have the built motor, 3.8, and P&P heads.

 

Are you still GT700 or did you move up to the GT800?

 

There are different ways to skin the cat....
gt30/76rs (not in kkk housing) did mid 800s so its doable. A slight port will do the job no need to get crazy on the heads... stock heads flow really well.
I will say it out loud that the 3.8L set ups so far have not been too promising... from what I hear its very very important to get a good 3.8l kit. When I see 2 or 3 cars running around with 3.8L kits successfully is when I will give my blessing.

 

I too have heard there have been some issues with the 3.8 kit. That being said alot of people think that porting and polishing the heads is critical and I know you are not real big on that. When I spoke to Todd K he didn't mention anything about needing upgraded halfshafts or a stronger clutch.

If I am not doing hard launches at the drag strip do you think I will need to upgrade those two things? I have a evoms stage 3 clutch right now.

 

Buddy ,how many miles since your motor was built?

 

There is a big difference between the new 800's and a gt700 parts wise like bigger turbos, larger fuel lines,a completely different custom fuel system(including custom fuel rails ,dual in tank pick ups and regulator),headers,throttle body y-pipe and so on.There is many hours in the fuel system alone just to do it right and make it look like it belongs on a Porsche.Evoms fab work is high quality,something you have to take into account when modding a Porsche.For me if it looks "backyard boogie" it doesn't belong on a Porsche.JMO

 

I still have the gt700

 

To make 800 or so horsepower your fuel system needs this.. FPR, two bosch 044, larger rails, larger lines and larger injectors. I think this set up only cost me around 3 thousand but I dont remember exact numbers. Now to make more than 850 rwhp power then you will need to spend more for fabrication of in take pick ups and what Joe stated above. I can give you where to buys these items etc..
I hope this helps

Joe,

Around 10,000

 

Im not sure how much the pressure plate holds on a stage 3 evoms... I have a feeling it may be OK. find out what the pressure plate is rated for?
