Honestly, there are so many variables it is very hard to say. What I find VERY interesting is how much 'progress' have we really made engine wise over the last 20-30 years? Perhaps direct injection, maybe some weight savings? Look what Mitsubishi, Subaru and others were doing with stock 2 litre turbo engines decades ago.
Pumping more than 20 psi in an engine with stock internals, fairly high compression, and a relatively lean AFR seems like a recipe for disaster in my understanding but I am by no means an expert  |
Damn haha now I'm rlly confused as to whether I should get a JB+.
