    just wanted to bump this project back up... its still in progress... currently searching for a good motor candidate. So just to recap... i need to pick up a newer engine 08+ with the e67 ecu?

    also... i wanted to share this... this is the motor that got the idea started back in 09'... i met with the guys this year at the Gatornationals (top fuel drag races) and got a few pics of the engine... its a trailblazer 4.2 I6 thats been converted to carb and a distributor ignition system... its been destroked a bit, built, etc ...makes 600+whp NA!!!

    also... from what I read... the LL8 guys are asking for an OS (im assuming oxygen sensor?) that reads more than 1 bar of boost... apparently... the stock ecu likes to throw the car into limp mode if it see's anything more.

    opinions, comments, suggestions?

    It has to do with the internal PCM code and the fact that the PCM uses a hybrid alpha-n/Speed Density fueling model.

    But, this is only applicable to the 02-05 P10 PCMs, hence why you need to look for an 06-09 motor. As I stated before, use an 07-09 motor and pair it with the E67 ECM and the T42 TCM (if you run a GM trans).

    Summary: Buy an 08-09 motor complete with the wiring harness to make it dead simple, an 07 motor will work if you use the 08-09 wiring and ECM/TCMs.

    The E67 can run up to 2.5 Bar of boost in stock form, just scale the VVE properly and run a 2 or 3 Bar MAP sensor.

    Awesome info Scarab! Thank you!

    So the newer engines should do fine with tuning on boost?

    Now here's my next question... purchase an 08-09 complete engine but what should i run for a transmission? Ive seen the supra swap and i've asked a few questions over on trailvoy

    Not real sure about what clutch/flywheel to run and what options do I have for trans?

    Well all the engines would handle it lol, just couldnt tune the 02-05 PCMs to compensate for it. But GM redesigned the motor in 06 so you're better off with the 06-09 motor anyway.

    Trans, Id talk to the guys on the TrailVoy forum. limequat is using a Solstice trans, but I dont know what the Austin-Healey guy is running. I can help you with the electronics side, but as for the trans thats up to you as I dont have a clue.

    thanks again...

    limequat and trout got back to me about the trans setup. just a few more questions to be answered and we'll be off and running

    so look for an 06 motor... didnt the 06/07 come with a different ecu than the 08/09's?

    No, look for an 07-09 motor. 06 motors have the "old-style" aka 02-05 crank reluctor (7x) whereas the 07-09 motors have 58x reluctors. The 06-07s use the P12 PCM (which is better than the P10, but not as flexible as the E67/T42 found in 08-09). If your plan is to boost and you're looking for good boosted support, get an 07-09 motor so you can run an E67 (while if you buy an 06 motor you'll be stuck with the P12). (Look at my post, #14)

    02-05s use the P10 (all years interchange)
    06-07s use the P12 (06s are compatible with 04-06 Colorado/Canyons plus others, 07 is unique to 07)
    08-09s use the E67 ECM for engine control and the T42 TCM for trans control.

    btw, OS would be referring to 'operating system'
    9.8@150 . LQ4 Turbonetics Billet 7575@18psi, 6 speed, non-intercooled with meth. Speed Density, open loop, no PE.
