Stock 92 Laser 4G63T motor, tranny, engine and tranny harness ECU and TCU everything that had to do with the motor went into a 94 Eclipse GS (auto FWD). All items left stock except BCS restrictor removed, stock air cam front 1/3 removed, lower honeycomb and air silencer removed
First drive max 300 yards
Would not go over 2K RPM
Boost leak test found 2 bad hoses-fixed them
Also leak from throttle body
Replace throttle O rings via this page:

Leaks gone holds 12 PSI at least 20 sec, manually released the pressure after 20 sec. Drove same 300 yards SAME PROBLEM
Check TPS according to:
http://www.geocities.com/motorcity/downs/7678/dsmtests.html
Seemed within range also tested old motor in garage consistent results on both.
Read threads on DSM Tuners stated unplug TPS and drive still no passing 2K RPM's
New plugs and wires
plugs-gap . 028 NKGBPR7ES
Car smokes white-not super bad from tailpipe
(Need to do oil change)
No oil in lower inner cooler pipe
No shaft play on turbo, turbo spins freely
Don't know what else to check please help
Also vented BOV to atmosphere momentaraly to insure it was going off. It was and I reconected it.
