Ive been researching the topic and have yet to come across a reason for the difference in the ST185 ratings, the USDM engine only pulls 200 HP and 200 lb/ft of torque, while the JDM versions of the same engine make between 221 and 231, im almost positive that the engines themselves are identical, same bore, stroke, CR...etc, so where does this mysterious power lie hidden. Could it just be the difference in the stock boost setting, are the turbos the same, what gives?
I'd like to get myself one of these babies, and im wondering if i get the USDM version if it would be an easy matter of freeing up the 21-31 HP in there, this is only regarding the ST185 3SGTE, and not any other generation of the engine Also if anybody knows any place that would sell the USDM engines here in Ontario (maybe even Quebec), cuz id much rather not end up having to buy the whole car (im on a freakin' buget, university starts in the fall) |

just so i know, its the ECU that robs the USDM version of 31 HP?? Thats nuts, you can only optimize a car so much for 103 octane (thats regular in japan) and it wouldnt have that great of an affect, EGR valve does some of that by creating more back pressure than the JDM version sans EGR, but its only by a couple of psi, which shouldnt have a big effect, no more than 3-4 top end HP, but 31 no way, again the best thing i can think of would be increase the boost to stock JDM levels (10 psi, is it?) and that should have it back to proper 231 HP spec, if anybody has anymore info please post
thanks for the posts, i just wanted your opinions on the subject, cuz the 2nd gen 3SGTE is fairly cheap if bought domestically and i wanted to clear up the issue of the missing HP, 30 is alot when u think about it people, and if it can be had with stock boost levels then all the better, plus by not having to import the engine i save a ****e load of money, money that will one day (a year or two from now) be used for an AWD conversion, Muahahahahahahahaa |
