    Your build confuses me. 4" Downpipe? 650's?

    The 4" DP makes me think you're shooting for 650-700whp, the 650's tell me otherwise, as does your single walbro 255.

    A power goal is important.

    a smaller turbo isn't going to fit a 4" downpipe (most are 3") without getitng stepped.
    650's are way under what you'll be capable of.

    If you're looking for a STREET car, I'd go with something that has a smaller hot side and big cold side. I wouldn't go straight t4. and a 96 a/r is stupid on the street.

    t3 .63 on the hot
    to4s on the cold .70 a/r ish would be nice.

    Who makes that flywheel and whats the max HP it can handle? Most light weight flywheels cant handle high HP engines.


    Eagle H-beams can be safe upto 600HP with a good tune, I would upgrade to 1000cc injectors because you always have room to make more power on the same injectors.

    As for a turbo the T4 your looking at might lag to spool but it wont be too bad, I had a similar turbo on my LS and it wasnt too too bad.......Anti lag is and will be your best friend. shit dont be scared to use a bit of nitrous to help spool things up too, you have a engine to handle it.

    550-600hp isn't efficient for daily use... not in a Civic at least.

    450whp is about as much as you need for a dd. It can still be reliable and faster than just about anything on the street!

    i have a few friends here who drive around over 600 DD. If you have control over your foot than anything is streetable as long as its on pump gas and tuned to where you can drive around daily there is no problem having a 1000hp car.
    and yes 450 is streetable i agree but the HP is all according to what the owner wants ya know i just want a dyno sheet and then a good e/t then i will be satisfied
