Well I come to this forum from cavalier forums due to the great support I've seen through searching this forum with the 3800 Super Charged motor. I did not do the swap with this car but i purchased it from the owner who had it built in by a company in Ontario in 2001. The motor came from a 2001 buick that actually fell off of the delivery truck with 5 miles on it and he purchased the full motor and harness. The shop then swapped it into this 94 cavalier using the getrag 5 speed, custom solid mounts, and a 94 Olds 88 pcm. Right now and for the last 11 years its been an OBD1 car for some reason instead of utilizing the obd2 of the buick. Below are the pics:
The car currently has a cold air intake, different pulley cant remeber size at moment, and tune from the shop that built it. My reason I am looking all over the internet for support is that currently my AFR readings are lean under boost. I dynoed the car and from 4k and above its in trouble. The only things I have changed since buying it that could affect the AFR would be the change of intake routing/filter, spark plugs, new belt tensioner/belt(doubt last one matters). That said I still beleive that its just time for a new tune and am currently waiting for my Zeitronix wideband data logger to come in the mail any day now. I then have a guy that can tune the chip shown in the ECU.
Plans before spring car season:
-OBD2 swap (found a 99 buick park avenue with 3800sc at JY thats all together and only $40 for harness/pcm)
-New clutch (racing clutch in it now is overkill and annoying around town)
-Headers? (been reading on this forum)
-SC and throttle body porting? (searching forum)
Basically looking for my options to improve on the car as is without compromising daily driving to work in summer. The car has a manifold back 3'' stainless exhaust.
Thanks for looking or guidance,
