hi guys, i have just installed a brand new 2.1L shortblock, now i want help with the timing.

i already had a 2.1L but the engine had a failure, so i ordered a new one from buschur racing.

first i was using the 4g63 timing belt with skunk works cam gears, but now i'll be using 4g64 timing belt, i wanted to know if the timing will be the same as on the previous belt or the 4g64 timing differs from 4g63?

 

these timing marks were from the previous 2.1L engine with the 4g63 timing belt.

will the timing marks be the same with 4g64 timing belt?

 

If you have a 4G63 head mated to your 4G64 block then this might help you out.

Get a piston stop. The 64 has more dwell time at TDC. Then set the timing. After it it locked into place, line up the inner gear mark to the valve cover. Do not use the outer mark or you will be 3.75+/- degrees off.
