im thinking to turbo my 92eg hb si - or as a result just go straight NA w/ b18c1 / c5 is it really worth the$ to jump up to c5?? thanks for advice

 

If you know how to build your own turbo, it will be incredibly cheaper with relatively the same hp, based on the reading that I've done.

I recommend getting a used t3/t4 turbo, pushing 6-8psi, VAFC, Boost Controller. You can do a custom setup for under a grand if you are patient and hit 13's relatively easy.

Isn't the c1 like 13.8-14.2 with i/h/e on street tires? and the c5 about .4 faster with the same mods?

 

yea i figured at 8psi id be making 13.9 - 14.2 prety consistantly .. i think i might go that way ,, but the dohc looks much meaner hahah

 

you coudl do a b-series swap and turbo that or build you d and turbo that. there's enough support for the d-series to break 400whp pretty easy and still be pretty streetable.
