I recently bought a 1991 legacy turbo 5spd. My first subbie. The previous owner installed/did the following:
-enclosed block 2.2 bored out to 2.4
-replaced all exhaust valves and lapped injectors
-04' WRX turbo
-06' WRX top mount intercooler
-excedy clutch
-Manual boost controller (@11psi)
-Turbo back exhaust venting to atmosphere
-Aluminum headers
-Aluminum pistons
-HKS bov
-boost gague
All of these additions have around 5,000 miles.
The problem I am having is that the engine/clutch slips when driven hard in top gears. 1st and 2nd pull strong, but I drive like my grandfather above that.
I find it hard to believe that this racing clutch is already busted, but I cant think of any other causes. If you guys have any suggestions for the slipping, or any other mods that might help my performance, please let me know
Thanks
