It is the 82, the block has been bored .020 over and decked to zero from piston face to deck, stock 4x4 camshaft
Wow… that’s the best “detail” I’ve read in a long time!
What you described is why I believe the 22R is Toyota’s best early designed engine ever. You can make it go from mild to wild, and increasing performance can be done without melting your credit card.
I messed with ignition timing a lot on my 1985 22R.
And for me..... I don't need a PhD in Automotive Engineering to do it!
Do you know what the compression ratio is? What octane gas are you burning?
I’m curious what a more aggressive cam profile would do for your butt dyno?
What is your objective in “messing” with the ignition timing?
Although I am always fascinated by and get a kick out of reading about anyone "messing" with their vehicle, for whatever reason, I don't believe I'm going to read about an astounding revelation or some amazing discovery as result. The DIYers have, historically, made changes to factory designs and components that can change performance, especially racing applications.
However, its difficult for me to understand how an average backyard mechanic is going to out "engineer" the Toyota automotive engineers, who are arguably the smartest on the planet, working for the 6th largest world-wide corporation, and get to "mess" with their engines and stuff in a multi-billion dollar shop,
.....and they've been doing it for about 80 years!!
Gnarls.
