Cams?

Hey guys ..... How do you tell the difference between turbo and non turbo cams ??

I don't know if they have any identifying numbers on them, but it's possible.

Other than that, the only for sure way I konw to tell is by getting a degree wheel and degreeing the cams.


Here's the specs btw.

Valve timing DOHC
cam ID mark (B,C) (A,A) (D,C) (E,A)

Intake valve
Opens BTDC 21" 26" 21" 16"
Closes ATDC 43" 46 "51" 48"

Exhaust valve
Opens BTDC 57" 55" 57" 55"
Closes ATDC 18" 9" 15" 9"



2.0 DOHC non turbo cam specs all years:

Intake valve opens 26 deg BTDC and closes 46 deg ABDC for a duration
of 252 deg Cam ID mark "A" 1.4 inch cam height
Exhaust valve opens 55 deg BBDC and closes 9 deg ATDC for a duration of
244 deg Cam ID mark "A" 1.39 inch cam height

2.0 DOHC turbo 5 speed up to 1994:

Intake valve opens 21 deg BTDC and closes 51 deg ABDC for a duration
of 252 deg Cam ID mark "D" 1.4 inch cam height
Exhaust valve opens 57 deg BBDC and closes 15 deg ATDC for a duration of
252 deg Cam ID mark "C" 1.39 inch cam height

2.0 DOHC turbo automatic up to 1994:

Intake valve opens 16 deg BTDC and closes 48 deg ABDC for a duration
of 244 deg Cam ID mark "A" 1.4 inch cam height
Exhaust valve opens 55 deg BBDC and closes 9 deg ATDC for a duration of
244 deg Cam ID mark "E" 1.37 inch cam height

2.0 DOHC turbo 5 speed AND automatic 1995 and after:

Intake valve opens 21 deg BTDC and closes 51 deg ABDC for a duration
of 252 deg Cam ID mark "J" 1.37 inch cam height
Exhaust valve opens 57 deg BBDC and closes 15 deg ATDC for a duration of
252 deg Cam ID mark "J" 1.37 inch cam height

If this is true, then why do i read about people noticing such a difference in cam lobe height and whatnot between the various years. I did a search through here and I found people talking about the 93s being the most agressive. Is there any truth to this? And where did you find the info you have here? And what about the different marks they have on their cams? I've heard of people having a "G" or a "K" also on their cams, what about those?

I'm not trying to be a jerk, but I think there's info missing, thats' all.
