Ok, so im building my first turbo build. Its going to be in a 92 GS-R, i was hopeing i could get a hand from you guys and tell me what you guys think about my set-up, maybe if im missing something or anything like that. Heres the list:

HEAD:
-JDM b16 head
-buddy club valve springs and retainers
-JDM ITR cams
-JDM ITR manifold portmatched with a blox 68mm throttle body

BLOCK:
-JDM b16 block
-JE 9:1 pistons, stock bore
-eagle rods
-arp studs ALL around
-blox blockguard
-cometic head gasket

TURBO KIT:
-turbonetics t4/t04e 60 trim turbo
-tial 38mm wastegate
-fab-works ramhorn manifold
-hks ssqv
-godspeed front mount intercooler
-blox boost controller
-3in. downpipe
-all turbo lines and fittings
-spoolin performance charge pipes


CRAP:
-delphi 550cc injectors
-walbro 255lph fuel pump
-hondata s200 with boost
-half size radiator
-autometer boost gauge

I think thats all i have...what do you guys think? any suggestions? parts im missing?

 

anybody?

 

Personally I would go with oversized pistons and bore the block out. You're looking at saving maybe 150 bucks by not boring it out, and I believe that being able to setup your bore size perfectly to get the correct piston-to-wall clearance is a key factor in having a strong, healthy motor.

 

Might want to get bigger injectors

 

What power are you aiming for?

And yes, i've gotta agree with getting oversized pistons! Gotta be done if your building a forged engine for boost!

What about bearings? Don't forget about them whilst the engines open. I replaced the oil and water pump on mine too whilst it was in being worked on, just for peace of mind

 

I would run minimum 750cc injectors. Its better to have more fuel then you need, instead of not enough..

 

so bigger injectors is something i will do forsure, those were going to be the ones i was going to use on stock internals and 8lbs of boost

 

im aiming about 350, if possible more. but i think im just going to see how i do with this set up since the block is already assembled. As for the bearrings i have ACL race bearrings. For the water and oil pump i went ITR.

 

keep them coming guys!

 

Larger injectors and a fresh bore as mentioned. If you only plan on boosting it 8psi I'd upgrade to 10:1 compression. It'd be funner to drive and would be no problem for a good tuner.

 

nothing wrong with keeping it lower compression, something like 9.0:1 will be fine and you will have more margin for error if you wanna go bigger. Trust me, its something that will happen eventually

 

the block has a fresh hone, and all the rings have good clearences. So on my set up, what would be the most boost i can run? about 15lbs?

 

if it has a fresh hone.. but stock bore usually when its done they take 2 or 3 thousands off? or you do it your self? you could be safe running more then that with a good tune
raa Lcpl!!!

 

well it was all done by a machine shop. i took the block in along with the parts, they honed it, sized the rings, checked clearences, balanzed the crank, and assembled it.

 

a blockguard would probably be a good idea right? any suggestions on what brand i should go for?

 

You should get a 3bar map sensor and bigger injectors as mentioned b4.....o

 

and a boost controller ( i would go with the dual stage)

 

You can do alot with a good tune, the tune is the most important aspect. Also I'm more comfortable with a fresh bore than just a hone cause it allows for a better seal if the machine shop is good, but that might just be my own superstitious thinking.

I think block guards are a waste, stock sleeves can take more than most people think. Save your money and put it towards sleeving if you are really worried.

Does he really need an AM map sensor if he is only doing 8 psi?

 

stock map sensor will do for up to 10.8 psi, anything more then that you need a 3bar map sensor.

 

im actually looking into boosting maybe 12 to 15 psi. were can i find a good map sensor?

 

i have a blox boost controller, that should get the job done

 

jus boost the **** out of that damn thing

 

WISH I CAN HELP MAN BUT LET ME KNOW HOW IT RUNS
BUMPS ON THE MODS

 

I have a brand new MSD map sensor w/o the pigtail....for 45 bucks..lmk

 

Tune on low and high boost....you be 400+++...lol...gl...keep us updated
