Ok, my car is at the tuner right now where it will remain for the next month. I am really hoping for some good numbers and just throwing out there the mods and hoping to see what people think so i maybe have a ballpark of what to expect. the mods are as follows.

1)gt35r
2)precision 650hp intercooler
3)2 1/2' piping
4) apexi full 3in exhaust
5)1000cc injectors
6)build bottom end (cp pistons, bc rods, )
7) bc 272 cams
8) 3mm headgasket
9) dual walbro 255 fuel pumps
10) aem ems
11) POSSIBLY inline pro fuel rail
12) arp head studs
13) act stage 5 clutch

hoping i can turn the boost up past 30psi. not really worried about the rear dif or tranny right now. thats winters project. At maximum psi what kind of power do you think this settup should be putting down and on what psi level. Once again it doesnt have to be exactly correct just trying to see a balllpark. thanks

 

Why on earth are you using a 3mm HG when the bottom end is built? Didnt you have the bottom end built for boost and lower CR?

BTW, if youre going to be running race fuel, that turbo will limit you to about 650 whp but that also depends on what manifold youre running. You didnt mention that.

With this setup, minus the 3mm HG and depending on what the final CR is on the built motor and what turbo manifold youre using, you could get to anywhere from 550 whp to 650 whp, but it also depends on if youre using pump gas or race gas. If youre going for e85, the 1000cc injectors will limit you to about 550-600 whp.

 

Why on earth you using bc cams is more like it lol.

Your build should produce around 520-530 wheel on pump I would hope. If you ditch the cams. If you dont then I dont know

Also 30psi wont hold just fyi plan on it spiking then dropping

 

^^Thats true also. The BC cams suck from what I've heard. People losing HP just going from the stock cams to the BC cams.

 

the bc cams havent been confirmed. They threw parts for fueling and the head that i could possibly use. I have a week to decide what exact parts I am looking for. Currently it has the inline pro turbo kit on it. Inestead of the log manifold we had a custome manifold made. I am thinking about going with the t1 race manifold. So if a 3mm headgasket isnt the way to go and if im trying to hit 650. What is the best route to take to insure that I make that? Please, advice is good at this point! nothing will be taken the wrong way, nor will I get offended. Thanks

 

get rid of cams, 3mm hg, then use a ELTM mani, make 500+ on pump, make 650 on race gas, or meth injection.

 

I agree with what everyone else is saying.

1. You're getting a built engine. I'm assuming with lower compression pistons. The whole purpose of the 3mm head gasket is to lower the compression ratio when using stock pistons. Therefore, you don't need the head gasket. Aftermarket headgaskets are also a common failure point.

2. Ditch the BC cams. I wouldn't put anything BC on any car.

3. Go with a nice tubular manifold. Full-Race, PFAB, etc.

Depending on what compression ratio you go with in the engine build, you may be able to max out the turbo on pump..... maybe. That'd be about 600-650whp.

 

Ok, I am throwing the bc cams out of the question. Should I replace bc cams with other cams or not? the compression will be 9.1. Any other pros/cons to the other parts i have settup. Or anything i should add besides race mani? As said before, any info is helpful info. I'd rather get constructive critisizm and fix the flaws in my settup versus dropping $8-10k and not even see a ballpark of the numbers I wanted. Thanks for all the help so far guys. Keep it going

 

Oh and btw, Do you know how much the 35r or 37r is just for the turbo by any chance. Im making sure im not getting charged out the ass.

 

they should be around the 1250 range
