Whats the difference between a USDM turbo II motor and a JDM turbo II motor? More HP (hopefully)

 

some emissions

 

There is no reall big difference between the two

 

if you get a good one there a cheap alternative to rebuilding the usdm engine, i believe i have seen them sell for about 700 to 800 bucks at a couple websites, the one moderator Vosko had 2 bad ones shipped to him after he installed them in his TurboII, correct me if im wrong?

 

Yeah, it's a gamble.. But as far a any difference.. There shouldn't be any internally.. Just bolt on stuff.. Like the smog crap might be missing which would give more HP, but that can be done on a USDM engine too..

 

What're some good places that sell jspec engines? I know fc3s.org is good, but there prices have gone up a little bit and they seem to have NOTHING in stock.

 

corksport.com has em and there suppose to be very good.

 

OK, thanks.



Here is a follow up though. I know that the turbo's changed on the 13b between 88 and 89, that said, how can a person tell which motor is which. (like i guess what the turbos look like or something, or engine #'s?)

 

the 89+ motors have an electronic oil metering pump on the front cover, while the 86-88 motos have a mechanical oil metering pump on the front cover... Thats the easiest tell tale sign of motor series
