I have a 1990 crx si with a d16 has 150,xxx miles on it and i am debating to either boost the stock d16 and maybe build up or do a ls/vtec, what do you think i should do and what is price range to get it done, if you have done this before please contact me, thanks

 

boost the d series will be cheaper. it will also be a lot cheaper to replace if you blow it up.

 

for just the price of mounts/linkage for the ls/vtec you can boost your d16, do that.
