If you look at the exhaust ports of a Gen 3 or 4 3s-gte engine, you will notice that cylinder 1 has a larger port then the rest (2,3 or 4)...

I'd like to see if anyone has either direct knowledge of why Toyota/Yamaha would have done this and or everyones theory as to why...

I could understand if the Exhaust manifold was a true full individual runner manifold and they did it to cylinder 4 but neither are the case so why #1...

Larger port volume = lower port velocity, so why would they want to lower the exhaust velocity of cyl. #1? ]]> Gen 3 3S-GTE CJMR2T http://www.mr2.com/forums/gen-3-3s-gte/Toyota-MR2-47098-interesting-change-gen-3-4-engines.html http://www.mr2.com/forums/gen-3-3s-gte/Toyota-MR2-47030-car-has-hard-time-reving-past-3000-rpms.html Tue, 17 Nov 2009 02:19:00 GMT finaly got my car started yesterday! it was pretty amazing. but when your driving it, it has a hard time taking gas at 3000 rpms but after you get past that at 5000 rpms it blowed out some smoke that was black. ive got no clue what could be causing this. so your guess is as good as mine. lol finaly got my car started yesterday! it was pretty amazing. but when your driving it, it has a hard time taking gas at 3000 rpms but after you get past that at 5000 rpms it blowed out some smoke that was black. ive got no clue what could be causing this. so your guess is as good as mine. lol ]]> Gen 3 3S-GTE tdj_1992 http://www.mr2.com/forums/gen-3-3s-gte/Toyota-MR2-47030-car-has-hard-time-reving-past-3000-rpms.html http://www.mr2.com/forums/gen-3-3s-gte/Toyota-MR2-46730-who-running-greddy-turbo-kit.html Wed, 04 Nov 2009 16:19:23 GMT Hey guys just looking to get some reviews on the GReddy turbo kit's out there and what your impression of the kit's are? I know there are quite a few out there but I really like the fact that the GReddy kit comes with a nice equal length mani that is TIG welded. So if anyone has any info it would appreciated.

Thanks,

Toyota's setpoint is 1.5% throttle open, but the gauge thickness does vary from throttle body to throttle body do to dimentional factors of the stop location and throttle linkage....

So if someone knows the exact gauge thickness set point for a Gen 3, it would be greatly appreciated if you could let me know what it is.
