Hello everyone,

As of now i have an internally stock gsr (b18c1) with a 18g greddy kit running about 10psi max. which makes ROUGHLY 245-250whp/215-220wtq.

I would like to have about 350-375 at the wheels and no more since its still a daily . My question is what all would i need as far as internals go? forged pistons and rods? (would that be it?)

I know there are some "freak" b18c1s that have run upper 300s stock internally, but i want to do it very safe and reliably.


On to the turbo...obviously i would ditch the 18g and most likely the t25 flanged greddy log mani. in favor for an equal length manifold and a larger turbo. I like the Garret GT ball bearing turbos for their fast spool so i was looking at the GT2871R (which would allow me to keep the log manifold i have). Would i want the .64 or .86 AR? I was thinking the .86 so it would hold boost to high RPMs, esp. if i upgraded the valve train.

Would this set up be good for my power goals? Im running hondata for EM.

THANKS

or a T3/T04E 54 trim, 0.60 ar? for about half the price? lol

Yeah, pistons and rods should be all you need. I can't comment on your turbo choice though.

Precision SC3431RE
gt3040R or gt3071R

These would all be great.

Pistons/Rods along with one of these turbos would be great.
Don't forget about larger injectors & dyno tuning etc.

Integra21

what about the gt2871R? its good for 400whp according to full-race which would also help with spool being ball beaing and all.

so a decent turbo as mentioned, forged pistons and rods, injectors (750cc???) and tuning would yield my power goal?

also what size/type of piston should i look for? 9.5 Cr? 9.1.cr?

Thanks GUYS

*mtber, i hear you tune hondata now

Integra21

the gt2871R would also allow me to keep my current log manifold

gt30/40r bro i made 375 off 10lbs of boost with that turbo i do have other **** done to my motor but if you are looking for that hp with a quick spool that is a bad *** turbo(and you aren't close to maxing it out, so later you can go higher)just my .02

Integra21

i like the gt2871R since it is good for 400whp. the other turbos mentioned are nice but i dont plan on maxing out this turbo. i only want 350-375 since it will not be a track only car, but a "quick" daily driver

plus the gt2871R has a t25 flange which would allow me to keep my manifold.

A nice turbo set-up, engine management and good tuner should be all you need to accomplish your goals.

obviously

im asking what the best set up would be. which comp. pistons? what size..81.5? which turbo etc...

thanks

b18c5GT2871R

i got alomst the same set up as you, exept the engine, mind is a b18c5,
JE piston
Eagle H beam rod
880cc injectors
rld manifold
hondata s200b
Gt2871R with 0.86ar

i should be in the 325-360whp i guess(94 octane)

thanks</TD></TR></TABLE>lol i didnt mention them for a reason(pistons). You can accomplish those "numbers" with an internally stock, or stock block set-up given you have the right fuel set-up, engine managment, and turbo set-up.I would just rebuild the motor, use arp rod bolts n headstuds, a larger intake manifold and tb, aftermarket valvetrain with some Type R cams n gears and a valvejob if the head is off. rest of the money would go into building the tranny and boost controller and dyno time. I really wouldnt get a gt-series turbo if i was on a budget, there are other turbo's that can give you the same peak numbers you desired and save some $$.

But imo a better way for you to figure out a set-up is instead of using which peak numbers you want, which can meen nothing mind you. would be what E.T and trap speed you are looking for.

the engine has 25k miles on it so i wouldnt imagine it would need a rebuild. I have also contacted a h-t sponsor about a full upgraded valvetrain. Correct me if im wrong but arent the GSR cams better for a boosted app?

since this will still be a daily driver i need full spool very fast and all the way to redline.

Integra21

what kind of power is safe on 9.1 or 9.8 cr forged pistons and rods and stock sleeves? 400whp? when do the sleeves start to go?

wicked2night

You're missing something. You're not even close to maxing out forged internals with your setup. And even you said that there are people pushing stock bottom ends in the upper 300WHP.
Since it's a daily driver and you obviusly have the money, you should get the pistons + rods combo. A 9:1 compression would be fine.
I hear you on the GT2871R, i think it's a good option. You'll get good spool, reach your HP goal, and still have something left in the turbo. Nothing wrong with the turbo if you can dish out the $$$.

Integra21

yea i know 375-400whp wouldnt max out the engine with the forged pistons and rods but i guess what im asking is how high could i run it before having problems with sleeves? just curiuos i guess, 400whp would be the most i want since i want useable power lol

also with forged pistons and rods, 9.1 compression would you guys recommend upgrading the valvetrain? if i did that i would need cams/gears etc also? worth it?

about the money...i make decent money, not growing on trees or anything (lol) but i have patients to get the best turbo for my set up. What would be a good comparison turbo for me in case money gets tight? (eventhought the cars nearly paid off ) thanks guys!

lollypopking

You say that 300hp on a stock bottom end is a "freak" occurance? I was under the impression that it is very possible given the amount of cars I have seen that have accomplished this. Their typical set ups are:

T3/T4 turbo
38mm wastgate
440cc injectors
255lph fuel pump
high flow turbo manifold (higher than a log)
3in down pipe

Fuel management has varied from person to person, but most run chipped ecu's and have been fully tuned. Typical boost is around 10psi. I am also looking into what is needed for these numbers. Now, I know you said 350-375hp, and that may be the reason fo the forged internals, but does anyone know of the reliability of the stock block when approaching the 300hp level?

Integra21

the reliability and the safety is the only reason i would get forged internals since it is my daily driver. yea cars have made nearly 400whp on the stock block but how long did they last???

I would have to agree. The GT2871R would be a great all around choice that keeps the FUN factor for over 350-375whp, without the need of purchasing a new manifold just to accomedate for a less expensive turbo. The B18c1 is a great platform to use....

would head work be worth while (valvetrain, cam gears, cams)? with my goal or would that be easily obtainable with the stock head?

what about intake manifold and throttle body? (skunk2? vector X?)

Soccerking3000

a stock head will get you there without a problem. Now if you want to get to 350-375 easier supporting mods can go a long way, such as P&P, cams, ect ect.

Integra21

excuse my ignorance about internals (pistons)

i would want the 81.5mm correct?

im looking at the ARAIS and Eagle rod combo

#3320202 81.5mm Turbo 9:1 compression - Inverted Dome (Dish)
#3310402 81.5mm Turbo 10.2:1 compression – Inverted Dome (Dish)
#3320900 84mm Turbo 9.2:1 compression - Flat Top
#3310000 84mm Turbo 10.6:1 compression - Flat Top

Soccerking3000

yea you want the 81.5mm to use the 84mm you'd need to have the motor sleeved

Integra21

very good

ive also read about how the AEM pullies can be detrimental to the engine, whats everyones take on this?

if so where's the best place to get the OEM pullies seeing that i dont have the stock ones?

thanks
