Anyone use these HKS turbos?

[pull'nslide]

Has anyone here used either of these turbos on there RB25?GT2835 Pro SGT2530 I'd be using a Peak Performance manifold as well.

My friend is running a 2835 Pro S on his R33 gts-t. He made ~390whp and 429tq at ~18 psi, though boost was dropping to ~10psi by ~6000rpm since he had a crappy manual boost controller. His car was relatively laggy as a result of horrible boost control, and IC piping that was absolutely horrible (custom, 90 deg bends, much longer piping than necessary). On a proper setup a 2835 pro S wouldn't be all that laggy. They're nice turbos but, the Garett GT series will work just as well and save you lots of money. A 3076r w/ .82 would be more than responsive and could still make well over 400whp, plus they're only ~$1200.

[pull'nslide]

wow, yea 400whp is about all I want, anything higher I dont rly need unless I just kinda make it. I'll be tunning with a Power FC also. Anyone else? These are gonna be the turbo and manifold I'm gonna get. I'll check out the garret's too. Also, have you heard good things about that manifold?

[lucky7]

which manifold?

[cdorhout]

which manifold?

Peak Performance manifold

[lucky7]

i just skimmed this like 4 more times. i FINALLY found it. im out of it today. yeah, thats the manifold i am planning on using. unless something new pops up in the next year or so.

Whats ur goals?

[pull'nslide]

I think there too high but can I use 850cc injectors with either of those turbo? I cant find any 600-700cc's. I only saw 550's and these. Ill be using a Sard FPR with them. Will those be OK or do you know where I can find smaller ones?

[M.O.B]

I ordered 650's yesterday from Deatschwerks. They also sell 740cc

[Carl H]

gt3076r ftw.

[BoostFab]

hks turbo are overpriced... go with GT series turbo. i think a gt35r would be a good match for the rb25

[pull'nslide]

The GT35R is gonna be more then I need, awesome turbo, but IMO it seems to much, I mean i could be wrong. Anyway, I've basically got it down to these link here, tell me which you think is the best bet, I dont need nor really want to go over 400whp, this will be driven quiet often daily, I have a backup car in case though. I'm also shooting for 11's on pump if I can.

35 is overkill for under 400hp...30r will be more responsive and make the power you want.

im running a hks gt2540 @ 12psi now and it rocks, i cant wait to take advantage of this turbos full potential.

[pull'nslide]

How much power are you making? I'm stuck between the two.

[RB20DETodd]

My co worker and i think around 240-250 whp, i wouldnt go any smaller than a 2540 if i were you id get the gt-rs.

[pull'nslide]

I think I'm gonna go with the GT2835 Pro S.What do you think the best injector size will be?- 650cc- 740cc- 850ccI'm thinking 740cc. This will be on the stock rail to I guess.

[RB20DETodd]

Nice Pro s balla $$$$$$$$, my numbers are on a rb20 btw. and 650's should be good.

[pull'nslide]

i'm shoot'n close to 400whp on pump, u still think 650?

[Carl H]

600's will be fine for 400whp, you'll be close to 80% dutycycle tho...

[pull'nslide]

eh, yea, well they are 650's, I guess I'll get those, anyone thing 740?U think I should upgrade fuel rails?....nvm, I wont be able to find one.

[BoostFab]

why don't you get atleast 72lb (750cc) ---they are not that much $ different, that way you're not going to max out your injectors if you decided more boost down the road!?! look like you're not thinking ahead.

[pull'nslide]

rly^^^^I was gonna go with those at first but everyone's been saying to go lower?read the last 5 posts, u'll see.I think 740's will be my choice since like said above, the 650's will run high on there duty cycle.So its gonna be the GT2835 Pro S with 740cc injectors.

[pull'nslide]

You think I should upgrade fuel rails?

[ISUJinX]

Switching injectors usually means you have to modify or replace the fuel rail with these motors. Going from side feed to topmount - unless you found direct replacement side feed ones. I didn't really look, just skimmed.

[melloscreama05]

what combo would you guys suggest for around 550 hp?

[Chaos the Xile]

A big frame GT30R or a GT35R throw some 720cc injectors on with a good tune should put you there. Give or take other bolt-on's depending on your current setup.
