cam differences

[beeztsi]

i am getting ready to do my 6 bolt swap in a 2g and i purchased a complete 90 turbo head. my buddy has an assortment of misc dsm parts lying around including multiple cam sets. is there any identify marks or visual differences between the 90 cams and 91-94 cams. if you have a caps cd help would be appreciated

I have searched the internet for the answer to this question. The most I can find is speculation that the 91-94 cams have a slightly higher lift on the exahaust side. I do not know how to tell them apart. I would love to find out once and for all if the 90 really does have different cams than the 91-94.

Here's what I came up with in my various readings; there is a letter stamped on the cams near the cam sprockets that is used to identify the cam. Intake cam with the letter "A" or "D" is the high lift cam. Letters B C E or F are the low lift intake cams. Exhaust cam C is high lift, cam A is medium lift, and cam E or F is low lift.

Also in the Haynes manual they show that 90- 92 are the same and 93- 94 are the same, with the later models getting a higher lift exhaust cam, but the same intake cam lift.

Haynes also shows the 93- 94 auto turbo cars got lower lift exhaust cams than the manual trannied turbo cars.

i've answered this question like 6547 times,i don't think you guys searched enough.
90 turbo MT/AT
90-94nt MT/AT
90-94 turbo AT had the same smaller cams.

91-94 turbo MT had the better cams,or actually cam,because its only the exhaust cam that is different, and it had .011" more lift.
