Changing timeing, on RB20DET???

[dangerous_daveo]

Now apparently you can change the timeing on RBs pretty easily, and it can have pretty good effect if done properly with boost, fuel etc. Now Im not sure if it really can be done, but if so how?

So does anyone know how to adjust the timeing a little?

Search the forum and read the several other previous threads about it?

Just turn the cas anti-clockwise (a very small amount) to advance...

Yep, as above but make sure you use a timing light. About 1 mm of movement can add a degree of advance, ut i wouldn't even consider turning in more than 1 degree atm due to the heat, and thats only if you have a frontmount, exhaust and cold air induction. Otherwise forget about it as you may damage your engine if it starts to ping at the top end under load due to excessive heat in the intake charge.

Well, after look at other stuff, looks like we can go for 12degrees, and still be quite safe.
