Changing timing on a 96+ celica ST, finally did the mod Options

[97sccelica]

Well i know that guys like Charlie wanted to know about this. here is the background info

on the 94-95 ST's the timing can be adjusted by loosening the bolt on the distributor and twisting it.

on the 96+ celica ST's with PIA obd2, the distributor is locked. the mounting hole in the distributor bracket is only big enough for the bolt that locks it,

what i did to fix this(since adjusting the timing is very important when you go turbo) is i took of the distributor and then took the mounting bracket off of that.

with that done i put the bracket in a vice and using a drill bit that was slightly bigger than the bolt, i elongated the hole to where there was about 1/4 inch of metal left on each side(to retain some strength) and then i put it all back on.

now i can adjust the timing on my car several degrees in each direction.

i will try to get some pics but i dont have a digi cam and im not patient enough to put mods on hold until i can borrow someones camera.

That is the best thing.

Get an ignition unit w/ timing module.

Well for college students, I guess the distr. is the only solution.
