JWT ECU REmapping

[HaLo]

I was wondering something.

I will lay my hand on a 91 S13 SE ECU, 91 Cams and a 91 flywheel.  Next spring, I plan to lighten that flywheel, swap the 91 cams with my 93 cams, install a better exhaust (N1 dual, or something mandrel bent around 2.5") and probably a hotshot header.

Would remapping the extra ECU from JWT would make a difference?  Any gains?  

In any case, what figures are we seeing at the crank? (I've got Injen Intake)  Would I be close to 200hp with the ECU remapping, headers, exhaust, flywheel and 91 cams?

At the crank, maybe.

How do you plan to lighten the flywheel?

A guy around here does a great job at reducing weight on a stock flywheel.  Won't be as much as an aftermarket flywheel though.

I was talking about flywheel hp, not whp.  WHP would be impossible without the proper $$$!  

Would the ECU retune make a difference with the listed mods?
