i have a 1990 civic si hb...it has a 1993 si d15 in it and i was wonderin what i would have to do to put a turbo on it....if you know a low cost way would be better....thanks

 

you could add a shot of nos to the engine. but if you did that or a turbo i would highly suggest building your internals. there is also a supercharger that you can put on your d series. i am going to be putting a turbo on in a couple of weeks and i have outweighed the pros and cons along with researching for about 6-8 months. i would suggest researching on what you want to do.

 

D15B7 or D15B2?

 

it is a d15b7
