Really depends on the power you want to achieve and how much you want to spend...

But lets say you want to max out the stock fuel system... 380-400 is about what Id stop at... (400 max hp if you have a really good tune, and I wouldnt run this everyday). 60-1 or gt35 either can be standard journel bearing or ball bearing your pockets decide... I prefer manlely rods bcuz they are rated for 1100 hp and the cost less then the carrillo H beams... CP pistons if its every day driving or JE for minimal driving... JE is made of a softer aluminum so it is able to absorb the stresses of detenotion better then the CP but they get piston slap at start up so over time the cylinder walls will scuff and the car will smoke after a while. I prefer supertech dual valve springs, retainers, and valves bcuz together they are rated for 15k rpm. 750cc injectors with one or two intake walbro 255 low pressure pumps... Port the exhaust runners in the head to gasket match. 2.5" exhaust with cut out or a full 3"... Greddy ultimate with 3 bar map sensor or full standalone from hydra. clevite bearings, arp head studs, and cometic head gasket.

This is the setup we use on just about every tc we build depending on the amount someone wants to spend... I believe there was someone in this forum that used an identical setup and made just under 560 whp on stock sleeves (not recommended) but the only addition to the setup was a larger more capable fuel delivery and return setup.

Forgot that 560 was on 19 psi and larger injectors but i think their wg was failing and they werent even able to achieve full boost... Not sure how that ended but definitely made good power...

so wat do yall think 8.5.1 or 8.8.1 or 9.1 i want to run a low comp so i could run more boost and timing safely

purevision01

9.0 to 1 is fine... Just a lil food for thought... Stock evo makes 315 on 18psi with a good tune depending on the mods... Stock block on honda b18c on the same boost and same size turbo will make 400... Evo has more displacement but lower compression... so to compensate for the drop in compression more boost is needed... Only way I would suggest going that low in compression is if you car was meant to go in a straight line... The lower compression wont matter because when racing you dont have to worry about gear selection... Everytime you shift your car will remain in its nominal rpm range.

This again is just my personal preference on how I build motors... Theres always more then one way to skin a cat, its just a question of how big a cat you wanna skin. lol

so u think on a GOOD tune and meth injection someone could run 12 psi daily driven? on stock internals just bolt on kit .

B_Real45

With a GOOD tune you shouldn't even need meth injection at 12psi.

The water/meth injection is just for added safetly - it's totally up to you.. if it makes you sleep better at night, do it.

SoFLo, should I invite you to go with my buddy and I when I'm ready to go to Japtrix? I think this will happen in like a month or so.

coryjames

the motor build has begun

darton sleeves
k-1 rods
je pistons

block is off to the machinist tomorrow or monday

time to max out the 30 r

B_Real45

You're not going to max out the GT3076 unless you get some headwork done...

coryjames

U think? lol talk to java he knows whats going on lol

purevision01

^^ agreed head work, intake mani, and throttle body and about 35 psi lol... and then you can go to the 35r if you like makin baby steps or if you wanna jump to the big dogs get the 40r and put that thing on a trailor.

B_Real45

I rather wait 'till it happens and see for myself..

caveman

I forgot to ask this question. Ive read this thread maybe twice over now, lol. I see majority ppl building their motor are running real high boost 15+ for example..

Ive been reading sleeving is really necessary for 350-400hp also. Sooo
What necessities would you say Im missing from a sub 10psi built motor?

Head PnP'd with upgraded VT
K1Rods
Higher Compression pistons (Having a hard time finding these, only finding lower compression, know where i can find them?)
All new ACL bearings
Head and block decked

boosthappy

ok i see what your saying so 9.1 is a good ratio what about the bore size 88.5mm or 89mm..thanks

Ya rob that would be great considering im going to have them tune me at 12 psi with meth in about a month .. we can all roll up together!

coryjames

i had a beautifull package when i got home lol one step closer to the final goal

caveman

Nice!!^^ congrats

java09

he has teh planssssss

coryjames

the plan is in the back of my 92 geo tracker going to ridge reamers to get cut and assembled tomorrow head will be on its way as soon as the "one off" special 2 parts get here lets just say my xb will be slow interior coming out this week hopfully for the jungle gym to be put in

boosthappy

im ganna go with the Je's 9.1 89mm bore dish piston what do yall think
