Yep, you're in a tough spot; not too many sanctioning bodies want to get into policing Frankenstein engines...and what you've built is devilishly close to the ITR engine, which is specifically excluded from STL. I'm pretty sure we could get you approved for STU (it would be worth a shot) but that's a World Challenge-level kind of prep. - GA

Your options...

ITE (depending on your region)
STU
Swap in a B16 and go STL

Come race!!!
