rumor has it that it will be the toyota celica GTS engine.
The problem with that engine is there isn't much out there for it. Plus www.prototyperacing.com already drop a k20a in the exige and been testing it and improving that ish. They are up to 280hp right now I believe (all n/a). They have plans for a 350-400hp turbo kit 
hrmm the celica gts engine has some good topend when their vvti crosses over, it's very noticable i think as much as itr vtec crossover. turbo XS is making a turbo kit for the celica gts motor soon it's supposed to make 276 whp on 6 psi.
