hey guys i need help picking out a turbo for my new set-up. i currently have a greddy 18g kit with 310cc it made 255whp 11psi on a stock ls/vtec. however i am aiming for 400whp this time with the new motor.

Cylinder Head Specifics:
1994 JDM GSR Head
Supertech Valvetrain (titanium springs & retainers)
OEM Valves, 5 angle valve job, new valve seals
JDM GSR CAMS
Skunk2 intake manifold
GReddy timing belt
Hondata intake manifold gasket
JDM GSR throttle body
450cc
AEBS Head studs

Engine Block Specifics:
1994 JDM GSR Block built for turbo
stock sleeves bored & honed .5mm over (bore & hone, hot tank)
1999 Integra LS crank
81.5mm 9:1 compression CP pistons
Eagle H-beam connecting rods
ARP 3/8" rod bolts
ACL bearings

will i be able to reach at least 350whp with the 18g and 450cc's? or will i have to upgrade turbo? and what manifold would be the best bang for the buck? i currently have no a/c but would love to keep my ps at least so far im looking at the sc6169, but not sure whether i should go with the "E, S, or SP" housing. your input would be greatly appreciated, thanks in advance.

Pm me for some baller prices]

setup will do 400 on 91 octane pump, approx 11.9 in full weight integra

autoX and track abilities with great spool characteristics

I'm not denying that it may be possible, but I wouldn't think it possible for the 50trim to make 400whp on 91 octane. One of my close friends had to stop pushing his 57 trim around 400whp on 91 octane...let alone a turbo with a smaller compressor. Just pointing that out...

schister66 do you have anything in mind for my power goal? its a dd/weekend track car.

First of all, you'll need larger injectors. I would just jump up to a set of 880ccs to give yourself room to grow. The last thing you want is to run out of fuel on the dyno and fall short of your goals.

As for the 18g, i dont really know a lot about it. That turbo isn't really designed around the flow of the Honda engine and therefore isn't the greatest cadidate for your setup. That's not to say you can't use it, but you could benefit from something tailored to your engine. Honestly, i woudl suggest a GT3255e for you. it is a great turbo that is capable of making the power you want (and more) while retaining the drivability you want for everyday bumming around town. I had a variation of this turbo, the GT3255b, which uses a smaller B housing rather than the E. It spooled quickly (3800rpm) and make power through redline. That would be my suggestion to you for a great street/track turbo with a HUGE powerband. If you want, PM me and i'll send you a pic of my dyno graph...
