rotrex c38r spec sheet

The c38r will be a big improvement ....the things that concerned me with it was ...1) 17-18 lbs would be too much for stock bottom end so you would be increasing pulley size to bring boost down to 14-15 which would contradict the supercharger upgrade by around 50% ...2) you would still lack in TQ for the expense 3k for new supercharger for around 2lb boost ...3) you could modify your supercharger kit over to boosted performance kit very easy ....remove supercharger and put everything back stock .leave motor mount in ...flip the intercooler around to put BOV on driver side ..use intercooler and upper intake pipes ...and everything else from supercharger kit .....buy the Comp turbo...exhaust piping ...lower charge pipes..wastegates ..and retune

Leaving motor mount opens up the area to run the air filter to the front above the sway bar for easier filter change ..right now you have to remove the turbo to change it

Interesting.

I’ve entertained the turbo idea a few times but I think I’ll stick with the sc for now, I have planned to build the motor even before I boosted it, I can do all the work myself which saves lots $$$, and have part supplier nearby here in Canada, might even give the jwt cams a try to, e85 will be a huge difference with the lower combustion temps, reduced detonation etc, my friend converted to e85 on his supra with amazing results, and seb at specialty z recommended it even on my current setup and ecutek will give even better results. I’ll post my e85 experience once converted
