thats not going NA to NA-turbo.. thats doing a complete engine swap.. make sure you understand the difference there...
alot of people are gonna tell you to use the search button, and in hindsight you now know you should
to swap to a 6spd and a 2jz-gte... its going to cost you more than it would to simply sell your car and buy a TT..
another route i suggest you investigate is simply turbo'ing your NA engine... all up its going to cost you less.. be less hassle ... and SHOULD give you slightly more HP than a stock 2jzgte...
if you have any further queries i do strongly suggest you use the search function in the top right corner.. as it is a common point of discussion/debate...
