Discussion
Just for anyone who may be interested, I found this while I was on a site, and thought it showed the difference straightline the difference between rev 2 and rev 3...

I think the main difference is potential TBH.
Bigger injectors
MAP not MAF
Lower Compression ( hence high boost in stock form)
Better Rods ( apparently)
Better Head Design ( apparently)
As you can tell I am not really into MR2's but that is my brief understanding
Very accurate. The rev3 turbo is also smaller and more efficient, and they run significantly more boost.
Found the old mail from PE

Just watched it, either the rev2 is sick (most likely) or the rev3 is tweekd, that's a hell of a difference over 1/4 mile. Did Flibbers supply the rev2?
Both cars were out of the box stock, no mods... test by best motoring, (won't get anyone fairer than those chaps, and they are all top notch drivers too!)
The 1/4 times for each seemed to be pretty spot on, give or take a tenth...

It has 20bhp more, and a better gearbox, torque is the same, although the rev3 can spool up quicker (what's quicker than instant anyway?). Terry was bang on the money when he said the rev3 had more potential, but it's only slightly more, once you get to (just an example) say, 375bhp, the advantage of the rev3 engine is quashed as you have to change a fair bit of stuff (will a CT20 give that much BHP in the fist place without major reworking?)
actually the gear boxes are the same in a rev 2 and 3 well rev 3's had LSD's as standard and LSD was an option on rev2's (which mine got! hehe) that's the only difference in the gear boxes.
Couple of points, I thought the GTS was only marginally lighter?
I was running 21psi on a Owens developement stage III hybrid turbo, no changes to fueling and ran fine.
And the LSD comment, they are only viscous, my rev 3 would still spin up one wheel if you accelerated hard on grass or gravel.

My rev2 won't...
It gets amazing traction even on gravel/wet roads. I've never seen a 'single' line of tracks.
Edited to add: There's probably some fun to be had trying to test this claim on a wet field...

Rev2 would have to be an older car though. No doubting the Rev3 has more power in stock form, but general consensus in the past from the owners club was that there really wasn't a great deal of difference in performance.
The ECU in my Rev2 seems to use any excuse to limit boost to ~6PSI, weather too cold, weather too hot, engine too cold, fuel not good enough, "wrong time of month" etc
