gonna put it in yourself or shop?
around here, i think this guy had a shop put in a usdm h22 and costed over 6k.

but w/ 150k you still have quite a bit of life left.

but of coruse, you can always get the JDM f22b (USDM H23) and turbo that. if you are lucky, you can probably find a complete swap for 600+ ship. then complete a nice turbo kit. sine it is non-vtec it should have a lower compression ratio which should be easier to turbo (less fuck ups)

it is all up to you though.
