i would get a custom manifold made or buy one if possible on ebay, that allows mating to mitsu turbos. i already touted this in another post but its worth mentioning again
mitsu turbos are consistently less than some of those shitty kits. this seems even more doable and realistically useful since my friend bolted a 14b onto his 86crx and ran low 13's on stock internals and he spent about 1000 for the whole car+used turbo+gauges+bov+etc.

not bad for an 86 crx with over 200k on it
