I am still working on my GSR Project (it's gonna be a few months if not longer ) but anyways I just thought I would get opinions on what boost level to run and what turbo I should get for an almost (3-4 days a week)daily driver? Below is what I am having done to the motor :

Block :

B18C1 Block 81.5mm overbored
Ross Pistons & Rings 9.3:1 Compression
Eagle H-Beam Rods
OEM Honda Bearings with Stock GSR Crank

Head :

P72 GSR Head - Port & Polished with 3 angle valve job
Skunk2 Springs, Retainers and Valves, ITR Cams
Skunk2 Intake
Cometic Headgasket

ECU / Fuel :

Hondata s200b and P28/P72 ECU Chipped with Hondata
550 Injectors
MSD SCI-L Ignition, Plug Wires
NGK Iridium IX Plugs

Drivetrain :

Type-R LSD Tranny (God help me get this!!)
400Hp Axles
Act 12Lbs Flywheel
Act Clutch

BTW the car is a 93 Civic Sleeper 4 Door. Car is never driven on long distances (no more than 60 miles or so lol).

Let me know guys - I am just anxious lol.

with upgraded internals i've read people boosting gsr motors around 18 psi and no problems. i wouldn't go over 20 just to be on the safe side

0BoostedJeff

measuring in boost is pointless, you have to limit yourself in HP. pressure varries between different size turbos, 10psi on a 16g is a big differnt than 10psi on a t67.

power wise, i have seen stock sleeved gsr's do 450

hope you have big injectors/ fuel pump/ rail/ fpr...

pcguy760

Forgot to add that in . Just did.

RacerXI

440's tend to be maxed out around 300whp. That's approx. 9-10psi (ballpark). I'd up that to 550's if i were you since you're buying injectors anyway. Don't forget your fuel pump either.

pcguy760

Yeah thanks for lettin me know - I did not think about that - Just upgraded it on my parts list . I was thinking about gettin a T04E Turbo ... heard those are nice.

adseguy

no need for that headgasket. OEM will work just fine for almost any power level.

Also get some 750cc's so you can do 500+HP if you want

i gota manifold for you .. hit me up, ive got this one and another with t3/t4 combo that would suit your needs better.

750cc's?? Wow this is gettin scary now lol - 500+HP on my unsleeved block?? I thought that the stock block could safely hold about 300Hp??

Thats a nice manifold man but I don't wanna waste your time - I am still building the motor and its costing me a bit plus I dont even have a tranny yet let alone the money to get one . So it will be a while before I start the Turbo GSR project. Right now its just the "GSR Project". It will be nice though once I am done.

I am trying not to cut any corners with anything.

sorry, I thought you were sleeved...haha. well the 750's are the same price so why no and the sleeves can hold to about 400-450hp. I've seen some 550whp stock sleeves run around as well. It's in the tune and how confident you are in it

FOrSfEd

I would agree, get the 750's and shoot for 400-450 hp. Stock sleeves should have no problem holding. I plan to boost on stock sleeves and I'm hoping for 450+.

Even if it is almost a daily driver??? - How long do you think the motor will last running like that? Also which turbo you think should I use - T3 or T04E? I do not want too much lag.

pcguy760

Any opinions?

RacerXI

I should have said this before, but seriously give yourself a real world HP figure and build your setup from there. There is no reason to have a 600whp capable turbo, but you're only using it to make 300whp.

Also, the most common application is a t3/to4e setup. They come in all sorts of sizes, configurations, housings, etc.

jnet

I am not sure which hp figure the B-series sleeves are capable of holding safely, but I know 14psi is on the upper end of what you want to boost with stock sleeves, safely.

no . NEVER EVER base it on PSI...it's HP.

Stock sleeves around 400-450hp. There are 550whp stock sleeve engines, but their tunes are perfect

jnet

It is true that different HP/psi #'s depend on the efficiency of the turbo and CFM rates, however PSI is a number, it's a very important number, its the pressure being exerted on the cylinder walls and no matter if you're making 20 psi and 300hp or 10psi and 400hp, 20 psi is still 20 psi, and the stock cylinder walls don't like much more than that.

Using a theory like yours would be saying I could run my turbo at 100psi but if its only making 300whp then the block is safe.

adseguy

Go ahead run 100PSI if you want. I can't believe you are really getting technical with me when you don't know what your talking about.

When a controlled explosion happens within the cylinder you have 1000's of PSI of pressure at a controlled rate (unlike detonation). adding 50PSI isn't going to change anything. The only reason that 20PSI gets dangerous is because you are adding a lot of fuel then and you will need a fuel to withstand the extra heat and pressure hence race gas is used above 18PSI or so. Other factors are involved, but this is the general idea why you can run 100PSI if you wish .

pcguy760

Hey thanks for all the help guys - yeah I was wrong to base it on PSI. Well, we all learn something new everyday! I guess once I get it together, I will have to find a good tuner somewhere in IL ...

Adseguy I noticed you're in IL - know any good tuners around here?

adseguy

i tune Uberdata on the street or dyno and I charge a lot less. I would recommend SuperDave from Whipfactory if you want a professional, but he only does Hondata or Neptune

pcguy760

Pm sent - thanks for the info adseguy
