Powerhouseracing has got alot of info on na/tt swaps. But I've heard that when you swap a 2jzge for a 2jzgte, a six speed is best to accompany it and that requires driveline and axel compents to be replaced. It gets pricey. You figure a Na might cost $5-10 grand less than a turbo but you'll end up spending just that much or more turbocharging an NA. If it's turbo you're going for just put all your eggs in one basket and but a TT. This is just an opinion from a 19 year kid that should'nt at all influence your choice. Hope that helps
