alright first off all say it's not my Infinite G20. It's my friends. It's an automatic. I'm a lot more knowledgeable about mechanical/ motors than he is. But he's learning. He wants to drop a different motor in his car. He's not wanting to go all out or anything. Just different motor, air intake, header, exhaust, and boost controller if it's a turbo motor. He's looking at getting a bluebird engine. Either that or a lil turbo kit someone is selling for his car. (http://www.jgycustoms.com/) is the guy that is selling both. My friend will probably take a loan out of the bank. He's only looking to spend $3000-4000 for everything. Me and some friends can install the engine and everything else. I got some friends that have dropped SR20DET's in 240's. and know about making hybrid nissan blocks... anyhoo. With that all being said. Is there any motors out there that you think would be good with the budget he's got? SR20DET, SR20VE, SR16VE.. anything else? with the $3000-4000 budget in mind.
