Why not, on a good conition 22re it would take 5-8lbs of boost(intercooled) without to much trouble. The biggest problem you would have is that the 82-84 ECU did not "understand boost", meaning they would be confused by it, the second big problem would be fuel, our injector are only 200cc we would need at least 250cc if not 300cc to protech against being to lean.
Of course you have the hardware problem to work out, extra engine cooling, extra oil cooling, oil feed and return lines for the turbo, a high-flow fuel pump plus some other small stuff to work out.
A compession ratio of 9:1 or 9.3:1 for the 85 owners is not all that high. The 2ZZ-GE powerd Celicas have been under boost and they have 12.5:1 ratio, plus the fact that there blocks are cast aluminium(not all bad) but there crankshaft and the rods are cast iron, forged steel like ours are. The ultra-high output S2000 engines have a supercharger kit..
Our engine the 22r/22re is the reason(one of) the truck became known as unbreakable, it was not because the engine were weak or fragile.
If our engines are fragile then why do they 200,000miles, 300,000miles or more?
EVeryone I know how has a 22re in their Celica have beaten the hell out of it, each one with over 150Kmiles on the stock engine. Not ONE has failed! Not one!
