Which SR20.. are you talkin about?S13-14 205HP, S15 250Hp. But there's also the 3rd gen. 3s. with 250hp. So i wonder which is more effective with mods. 3Sgte 3rd gen. or S15? good question.3SGTEs regularly make more reliable high horsepower than the SR20DET?[/B]
Yeah, the ECU is mapped for the USDM fuel.Originally posted by Kool_Aider@Oct 11 2006, 10:10 AM
Well i have a domestic 3sgte.. i should be good with 91 octane fuel then shouldnt I?
The 3SGTE is a pretty sweet engine no doubt, in fact, someday I hope to get a GT4, but your not giving the 5SFE the credit it deserves. It is also a well engineered intermediate engine. It wasn't designed for racing, but has decent power and great reliability. And yes, there are mods you can do to a 5SFE to gain power. However, these mods are few and far between. Obviously the cold air intake and cat back exhaust are possibilities, just like any car. If you want a header, you will need to modify the down pipe, and other than that, there aren't alot of cost effective ways to upgrade a 5SFE. If you really want power though, there is a turbo kit for the 5SFE, and you could modify a intercooler to fit. I don't know exactly, but I'm guessing a turbocharged and intercooled 5SFE would give a GT4 a run for it's money as far as power goes. Afterall, the biggest difference between the two engines is that ones turbocharged and the other is naturally aspirated. I still wouldn't race a GT4 with a "Turbocharged 5SFE" on a road course without major upgrades, to the suspension though. The GT4 isn't a drag car, it's a rally car, without the 4 wheel drive and suspension it has, it wouldn't be able to kick a** like it does. So I say do what you want, you don't need us to tell you what to do with your money, but in reality, it might be just as cost effective to turbocharge, intercool, put on a full exhaust with custom headers, and get a port and polish job done to a 5SFE, than to swap out for a good 3SGTE engine. That would be quite a project though.
