94_yota_4x4

I have been searching the forum and cant seem to find the information i need. I'm rebuilding my 22re and i have a new timing set and all that jaz. I have read that the motor is timed to 0 degrees, how far can you advance the timing before it becomes an issue? i have a new cam installed. new bearings and rings pistons and rods. any info would be greatly appreciated.

Not 0.

so if im understanding that right then i should be able to advance it a little more to pick up a little more power? i was just wondering if anyone knew what was too much timing? and thank you for the pictures

The mechanical timing, camshaft to crank, is set at 0* when reinstalling. Spark timing, when all done is set at 5* jumpered.

i understand that but since the computer takes over and moves it to 10 or so couldn't i advance it more when im setting the timing with the jumper in place?

No when you are putting the engine together you install the timing chain with the gears set at 0 degrees .

If you don`t then you are timing the engine by ear because any marks on the outside of the engine have no meaning.

This is your engine so by all means feel free to do as you will.

You want more power out of a 22re engine it is going to be expensive.

we still have that little bit of freedom.:jessica::jessica:

i mean if i install it like its supposed to be when timing it with a light i could advance it a little is what im asking i know that jumping teeth on on a timing chain isnt a good idea so i understand how they are supposed to be installed. i just was wanting to know if i can advance timing with a light.

Oh. Well, yes. Your rebuild comments made me thunk you were wanting to advance cam timing! Yea, you can advance spark for power, but it gets pretty touchy. 5* is baseline, the ECU will advance waaaay beyond 10*, as much as 30+, I believe. You go too far, get detonation, and your ECU doesn't see it, you'll burn a hole in a piston, quick, like a bunny. I'd leave it at 5*, meself.

ok thank you thats what i was looking for so i guess i can just time it like a 302 back in the day. advance till detonation and back off just a little. maybe timed like 7 degrees or so with the pin jumped

combatcarl

7, maaaybe 8*, you'd be OK. The 3.noballs guys do it to get a little more, but that's a different engine. One of the old ferts around here should be reading this before long, and say for sure. Who'd ya get the cam from, did it come with specs for this?

engnbldr.com is the cam and its the 268

If no literature about timing setup came with, try contacting him. He's around here, too. I hear he's good about helping with info on that stuff. Runs different valve lash specs, doesn't it?

94_yota_4x4

idk im waiting on it to come in still so i dont know yet

combatcarl

Ah. Set it up to cam builder's valve specs, factory timing specs and run the break in period. THEN begin playing with it. A V8, it ain't. Made to run forever, in tough conditions. Not make lots of ponies, and need a 50k rebuild!

Any time you change the timing, make sure you use the jumper in the check connector. Don't just loosen the dizzy and spin it. You can't adjust the timing curve, just the initial advance, and that HAS to be done with the jumper.

And don't rely on full throttle runs and listening for detonation to be your guide. Get it on the highway... since you're in Springfield, I5 is flat up to Coburg and beyond, and 126 is pretty flat out past Mohawk... and listen for pinging at light throttle acceleration. Adjust the timing so you don't hear that.

i do miss the v8's lol but i like my yota.

im not it springfield lol im in alaska lol and yeah im going to start with the standard timing. and go from there i dont want to push it too far right away
