Maybe with EcuTek and their claim to be superior to Uprev, still waiting to see that. I just want some educated guesses on what they think is possible, I know tuning the VQ motor is still very brand new and tuners have come along way.

Thank you everyone for your time.

So, unfortunately, no, it can't be done without an enormous amount of custom work and tuning it seems

I like ambitious projects, but my recommendation is to take on a different one: Figure out how to get a roots or twinscrew blower on this motor.

Same heads, same headers, same cams. You'd probably need a bigger fuel pump and injectors, and a tune. Oh, and a blower sized for a V6.

You'd need to figure out how mate the SC to the IM (fab work... I'd probably find a used M370 IM and experiment with chopping it up), some plumbing for a A2W IC and HE, and probably cut a hole in the hood, but it would give you V8 like toque and response right off of idle, and best of all, it would feel like a more powerful N/A car.

It would be awesome for a DD or road course car and no one else has done it yet. It would almost certainly be no more expensive or more difficult to fit than any of the custom N/A projects that have been undertaken, and it would have enormous potential above and beyond a high-strung N/A build.
