Most of the difference is intake manifold and ECU tuning. Also, in the last few years of the 2nd gen, there was an increase in compression ratio.
I've seen GSL-SE in C-Street Prepared (SoloII) make 170rwhp. This is with programmable engine management and 2nd gen intake manifold.
An ITS 2nd gen car should make 170-180rwhp. Maybe a bit more, but I doubt anybody would admit to it

Well...I am running a SE in what is equivalant to ITS. The airflow meter on the SE is very restrictive in comparison to the 2nd gen RX7 (13b). I can't personally say this is correct, but I have been told if the 2nd gen airflow meter is adapted to the SE there is a noticable amount of HP there. BUT this is ILLEGAL for IT racing.
Someone on this board told me adjusting the fuel pressure up to the area of 55 psi and timing around 20 degrees makes around 160 RWHP. I'm in the middle of making this change, so I can't comment to the gains.
SE: 9.4 compression ratio
89-91: 9.7 compression ratio
Intake ports on SE 13b are disgustingly small.
My advice is if you are thinking about IT racing and you haven't purchased the GSL-SE yet...DON'T...Goe for a 2nd gen RX-7.
You'll also appreciate the independant rear suspension of the 2nd gen.
Good luck.

Yup...the SE is a known dog in ITS.
Wouldn't mind having one in A though......

I have to agree w / you Jake....But at this time, I generally pull away from the IT2 (ITA) group while the IT1 (ITS) group is pulling away from me.
The SE needs to either loose weight for the ITS or gain a few for ITA. It seems to be one of those cars that fall in the middle of the classes.
Oh well....I'm still having a great time on the track.
