thats what piggy backs, a/f , and other electronics and tuning are for. also the effiency of sc on a engine also depends on the engine. over all turbos are better but they are also more complicated. sc are just the road less traveled and alot of ppl like that

I was under the impression you would need to dump the factory ECU and go with an AEM or something else.

Not if you put the throttle body and afm before the SC(on the vaccum side). It would run just like stock, Unless it has like a pressure sensor in the manifold. Then the car doesnt even know whats going on. Plus they have a built in bypass for idle so the car would idle normally anyway, Unlike most sc cars with loopy/bad idle.

And whats nice about the roots stlye blowers is they are making boost as soon as the engine spins. So from idle you have boost. They just arent good for high boost and high rpms.

guess it will be trial and error with new injector size

aem? isnt that a brand?
u mean an ems

Well you can just do the standard 550/lexus afms. but I think the stovks would be fine for 6-8 psi.

Aem
 

Yeah they make Engine management systems. They cost around 2400 without shopping around which is the ems you mentioned. Thats the brand that came to mind.

im trying to decide on supercharger vs turbocharger and i know that in the long run a turbo would be better, but im more into street racing where i need that initial kick of a supercharger to get going off that red light whereas a turbo has lag involved. what to do?! if anyone can throw me some estimates in pricing for a turbo and sc id appreciate it. 1989 5 speed:bow:

there is a supercharged mk3 supra.. check out toyota G motors..
