the 1zz is ideal for turbo, blowers, even NOS because of its low compression. with the 2zz you have a higher compression ebngine that not really compatible to turboes or blowers, sometimes even NOS. This isn't 100% true statement
i have known a few dicks that ran a turbo from XS and didnt lower the compression nor, re-enforce the internals what they do? blew their engines. i've told them before the compression is way too high for ideal forced induction. The XS kit was trash and THATS why they blew their engine. there's a million reasons why it was trash that I'm not gonna type out here. If you search here and the "other" celica site you'll see numerous threads why. we have successfully run turbos on stock internal GTS's as high as 10 psi and put down 278 wp and 207 wtq and that was in 1 tuning session on 91 octane. done properly the 2zz can handle it with no problems.
i have a a GTS, the 2ZZ work horse for me is just fine, i have had trouble finding parts, most of my parts are one-of customs, my pistons heads, connecting arms, my crank was balanced, and the tranny re-enforced. i have even upped the compression to almost 12.5, i have custom exhaust, trial headers, polished Intake
manifold, stage 3 portin and polishing. im int he middle of bumpin up the displacement to a full 2.2 with a custom stroker kit. good luck on the 2.2 because there isnt enough room to pull it off. you wont get over 2.0 out of it. it's been tried by many companies but in the end ther's not enough room. so good luck in your efforts.
needless to say the stock ECU met the trash can, computer work is managed by a Greddy unit. I highly suggest swapping the e-manage for the power fc. you'll gain a lot more tuneability and power.
its whatever works for you. how ever muc you can swing. lol im almost dont with the mods for my car, the last dyno ran it had before we pulled he engine for the stroker kit was 240hp, rivals that of a S2000. it got 228 ft/lbs. of torque. do you happen to have a scanned copy of the dyno? and was this crank power or whp? cause with the mods you listed those numbers are VERY hard to believe. so some more info would be nice. also have you tried takin it to the track? I'd like to see where your peak power/torque is made and how your powerband looks.
