I'm looking to spend something like 3k on an engine swap for my 1990 Civic D/X.. What would be my best option? What should I be looking to pay for whatever swap you suggest?

 

for 3g's u could swap a newer sohc motor in lke a d16y8 and turbo it or a dohc zc and turbo that as well or go b series and swap a b16 in. gsr swap might cost u a little more then 3g's but it would be worth it

b18c1

 

3g's...holy hell, if you shop well you could turbo a sohc motor with a forged bottom end....that's a hell of alot more fun than a GSR motor.

For 3k, I would go b16a... and the dx to b16a wiring at http://www.rywire.com
