I found this deal where I can build a 4g63. Is it possible to swap it to my N/T? If so, how hard is it to do? I am planning a build up. I have got the motor. Internally Balanced, .20 bore, crower cams, je pistons, aem gears, port and polished head, new valves and springs, tranny and turbo. Is the swap possible and if so how hard is it?
 
this not a Honda swap that you can do in a weekend. the GS and RS dont come with anything the same as the GST and GSX. You also need to get a new transmission, all wiring, the 2G mas, exhaust and intake manifold, you get the picture. It can be done but most ppl would probably agree just sell the N/T and get a Turbo
 
Anything can be done. But are you willing to put I dont know maybe 600 man hours in to it (25 days 24 hours a day)? You will have to fab new motor mounts Rewire everthing nothing is going to fit correctly. Next comes fabbing mounts for the trans. If you are going as far as to put in a 4g63 might as well make it AWD also so lets add another 200 man hours. Now for a price tag on that at lets say $10 and hour. (just how many shops will charge $10 an hour most are at $40 plus) we are at about $8,000 dollars in labor.
I am not trying to scare you away from your project. But I think you will be throwing away money at your project. If you decide to go ahead with it anyways Good luck on it.
 
yea, for the price of swapping a 4g63 into a 420a n/t car you could just go out and buy one thats already turbo, and sell your n/t to help pay for it

if u really want to keep your current car then look into a hahn racecraft 420a turbo kit, they can make pretty good power, one of my friends has the 420a super 16g kit on his avenger, and its pretty fast
