I am a mechanical engineer and i know pretty much everything about these cars so i know what i need to look for and what questions to ask but he wouldnt let me. And i told him to rev the engine up for me but are engines are limited to low in park to hear spool

it could be just a smaller turbo that would be easier to program and modify..
Sorry for getting everyone excited i want a turbo xfire as much as everybody else
Ill keep an eye out now i know what to look for since he lives somewhere close to me and ill make sure ill get some pics and get him on the forum
