    hehe.... nah, good luck spinnin that thing!

    The hybrid T3/04 is a good size if you will be pushing between 8-15psi. or even more if your engine allows.

    HKS 2530 or Garrett GT25R (380hp) would be my 2 choices. Beyond that, a GT25R with the .86a/r turbine housing (440hp) would be suitable. If you have a bigger budget, an HKS GT2835 or better yet, GT-RS would work a treat.

    just look at SR20DETs and they turbos that are using - should give you a good indication.

    I do know of an SR20 with a GT51SPL strapped to it.... I don't recomend...



    As for the engine, I suggest a little bore and stroke, 1960CCs or so (aria makes a piston for all sizes now for stroked B18s to run in under 2Litres) and maybe a B20z crankshaft......
    Go with some turbo VTEC killer cams (yes, scrap VTEC, you may as well) and aim for about 9.2:1 compression - you don't need 2 bar of boost.....
    Hook it up to a Hondata with boost kit, visit Sir DynoDave, and bob's your uncle, and you'll have an empty pocket

    t28 will be OK, but will run out of top end a little. The GT28's are a much better turbo.

    BTW [[danny]] you dont need a thicker headgasket whn running low comp forgies

    Hi there,

    running a thicker head gasket is a waste of money. The OEM gasket is more than upto the job

    if you want lower compression, don't do it on the cheap. Do it properly

    Alans got a great setup. T3/4 turbonetics is great for big power. Probably starts to spool at about 3500 rpm. Try not to lower the comp ratio too much so that this turbo will spool a little earlier. Forgies will lower the comp anyways so get an OEM gasket. Get rods and do some study on the fuel and ecu side of things. I would reccommend you take a good look at Alans setup. Pretty well built and made for big boost.
    By the way PORNSTAR is right, NA is gay.
