Probably not, unless SRT would be able to bore the cylinders and make a N/A engine have about 400/450 hp, look at the benz AMG models, they just use a 5.5 liter engine, I dont think they supercharge any of them except for the SLK32 amg, it is a reliablity issue, and why would lexus warranty anyone elses work when they're putting so much stuff in the car that could really do damage, unless they can just "TUNE" the engine then chances are it'll just stick like this. Just my opinion
