Obviously I used the phrase "I would think," hence me asking the question, why is this engine so limited?
Someone brought up the 2jz engine in another thread and it's a great example of what I'm talking about. It's a 21 year old inline 6 engine with twin turbos. No fancy Vanos, direct injection, twin scroll, or electronic waste gate. Yet with just exhaust and a boost controller (not even a tune), these cars produce over 400whp. With full exhaust, intake, boost controller, intercooler, and a tune (which is what OP is running minus the intercooler) the 2jz would produce over 450whp. And of coarse all of these numbers are repeatedly achieved using normal pump gas 93 octane.
So again, my question is, what is the limiting factor of these engines?
