The 22R-E is not considered a 'performance' engine therefore you will not see anything written up on its instalation.
If you don't have a thriving japanese second hand engine import market in your country, chances are you will never see a 1G-GTE.
This engine was found in the GZ20 Soarer and GA70 Supra, mid to late 80's.
Going fuel injected as opposed to carbs means either a surge tank and twin fuel pump set up or installing the entire fuel tank and pump set-up from a RA65 Celica, which has the 22R-E engine.....at least it did in Australia.
Easier still is an 18RG engine, but they are getting very hard to find these days.
