    yeah no worries fella's. was talking to mate tonight with a gti-r.. and his trying his mates gt35r on his car.. (mildly worked on) to see how much lag their is.. otherwise he might be settling with a gt3076r.. so really now until i find out how his sr20det goes with the gt35r.. will decide whether or not i'll go the bigger turbo.. at the moment i might be leaning towards the t28, gt3076r or the gtk350.. should do fine for the setup i want until i decide if its enough power or not.

    imo 3076 is the best turbo on a 2L for street anyways. with the extra .2 capacity it would be decent alot better than a 35

    yeah heard a good wrap about the gt3076r on 2 - 2.5l engines.. so it might be where im heading if i dont get convinced the t28 or gtk350 is better.. i dont mind a bit of lag as i have to stay under the radar with cops etc.. (obvious reason what licence i have) would like to change gears at 2.5 - 3k and not hear alot of turbo fluttering/bov noises etc.. so the gt3076r might fit in nice.

    ahh it seems for the meantime i have been given a gt28 turbo.. and a brand new intercooler.. will be seeing if the turbo runs alright on the prelude in the future.. and if not either upgrade or rebuild it. basically just need to look into ecu, piping, downpipe, tune and the other remaining things needed.

    cheers phattzy . what injectors, pump and ecu would you recommend? obviously am looking at the hondata ecu's, maybe a walbro 255? and am a bit uncertain with injectors at this point. my main aim is to be pushing 7 - 14psi through the h22a motor with near bolt on mods besides the things needed to make the turbo and motor run together with no excess fuel etc (being rich or untuned.)

    A GT28 on a stock H22 should be safe at around the 7-8psi mark and net around 150kW at the wheels. The turbo is capable of more but the engine wont last unless you start spending money to rebuild with better internals. For that sort of power a set of 550cc injectors should do the job nicely. The Walbro pump will hold well past the fuel flows that you are expecting to run. The Walbro starts to fall over around the 500hp mark..ish.

    Don't put 14psi into a stock motor... My H23 lasted 6 weeks on 9psi, and that was on a very safe tune.

    Stock internals i would stop at 7psi if you want it to last any sort of time, or go 14 psi for a week and then rebuild

    thanks for the input guys! i don't know if this is true or not.. but i think it was weapon.r or someone similar who had a h22a turbo setup and said you can run 14psi all day? wasn't sure what he done to the motor but the people asking the question were using a stock h22a motor. but yes i won't be running more then 9psi through the stock motor until i decide to start building it up properly. considering this will also be my main car once its done... but yeah will be running low boost daily.. and when i take it to the drag strip i might knock it up a notch.. one of thing as i don't go to the drags that much. ohh and last thing.. would trying to achieve 180 - 200kw at the wheels be to high of a goal even if i was to upgrade injectors, new ecu, new intake manifold, custom downpipe etc?

    You may just be able to run 14psi all day....for 1 day. I don't like its chances of lasting though. Your car, your risk. If it does go bang it can do more harm than you expected and then its time to find a new engine.

    The GT28 will start to find its limit at 200kW depending on which one it is. Safe goal is 150. 200 is stretching the friendship between reciprocating parts.

    yeah, i don't think i'll take the risk.. as stated this will be my daily driven car as i will be selling my zed for funds for it.. can't afford for this thing to go bang.. so i will stick to low boost which i'm sure will still be fun enough in itself.. get it properly tuned and then will decide what to do later on with it once i'm funded.

    I skipped over page 2 of this thread and I don't know if you still intend on putting a GT35R on a H22, but as someone who daily drives a 2JZ with a GT35R I thought I'd share my experiences.

    Even on a 3L motor, albeit rebuilt with a very low compression ratio (8:1), the GT35R is a little laggy. I can only imagine on a 2.2L (forgive my ignorance, but I assume the H22 is 2.2L) motor it would be a complete pig, although that may be remedied somewhat by high compression and E85 fuel. And beyond what the others have already stated about needing to sink a lot of cash into the motor to handle the sort of boost the GT35R is capable of, there are so many other factors which I never initially considered. Namely clutch, gearbox and tyres. Somehow my gearbox (w58) and clutch (custom NPC full face organic) are holding out, no idea how. With 235mm rear tyres, I don't get any traction until 4th gear (1st-3rd act like I'm free reving in neutral once boost comes on, but with added tyre smoke).

    All that being said, if you're prepared to spend the $$$ on the motor AND drivetrain, and THEN somehow get traction after squeezing massive tyres under your guards... then I have no doubt the car will be a total blast to drive if you can put up with the lag.
