ok i had my timing belt changed last week. the guy that changed it said the intake side cam gear ( stock cam gears) was retarded 1 tooth. So he put it back in time. i noticed my car wasn't the same slowed down alot. So i had to find out for sure, i took it to secret service to get it dynoed. very depressing results 10 whp less than i had the last time i dynoed there. Here's what really sucks the last time i was at 18psi and a high flow cat. this time i'm at 20psi and no cat. They thought it was a timing issue so i brought it back to the guy who did the timing belt change i stayed there to watch him , timing was on the money . So this might not be the smartest decision but i had him change it back to were it was . It feels like i got my power back . And its running good. i'm gonna get it re-dynoed to find out for sure. Did i do the right thing?

 

To me personally, it sounds right as long as you're using a diff timing belt than the old one

 

what cams do you have in the car? stock cams? if so maybe they're the non turbo cams. I am pretty sure the non turbo cams are advanced 5 degrees from the turbo cams ( which = about one tooth)

shouldn't hurt anything. you might want to get a set of cam gears and play with your cam timing a little on the dyno. you can get the fidanza cam gears for like $200 a set now.

 

i have stock cams and yes there turbo cams i have a GST and it was bone stock when i bought it.

 

the head has never been swapped? don't you have like a 94? well, the non turbo cams is the only thing I can think of that would make it perform like that.

 

i have a 98 GST, maybee your thinking of my friend Rodney he has a 94 1.8 non turbo that he swapped to a 2.0 turbo awhile back.
