How rare are turbo Eclipses where you are from?

Well there are all the basic mods you can do such as a intake, exhaust(headers, downpipe, catback 3" is always good) cam shafts(hks is good for these ). That should bring up your tourqe to a noticeable amount and bring up your top end a little also. After these basic mods things get a little bit more complicated(anyone can feel free to correct me if i am wrong). Head work always provides results(stage 1,2,3,4,5 heads) You could do new pistons if your compression isn't the greatest. Fuel injectors, Fuel pump.....etc...THeres alot of things you can do to tweak the raw 4g63 its all bout how much money you got, how fast you want to go.


Hope this gives you a insight on make the NT a little quicker.

Ok, thanks. Could i have any problem if i change the admision tube and i don´t fit the O2 sensor? ( i saw that it doesn´t appears in almost of performances)

Admision tube? Did you mean exhaust manifold maybe? I'd use an O2 sensor always as it will help with saving gasoline.

K what you just posted is kinda unclear to me but i will try to sum up a little more information for you. The sensors that came on the car stock are good to have and are there for a reason. If there not your ECU will want to kick your ass and either not let your call run at all, run lean, run rich, etc... So the 02, and all the other sensors i recomened leaving them. As for horse power like i said earlier you can make a fast all motor car but I am considering slapping a turbo on my nt. Its a great way to get easy horse power if oyu know what your doing. Also NOS is the best bang for hte buck jsut dont get greedy. But again head jobs, exhaust, porting and a few other things will get you up to around 200-300 hp depending on how much cash you got and how fast you want to go. I believe there is article on making the NT fast i will look for it for you and post it if i find it. Hope this helps. Any questions feel free to post or PM me.

Most of the 1G NT mods would apply to the european 2G NT
You need to keep the O2 sensor.

Because you have a 4G63 it's a lot easier for you to turbocharge the car than it would be if it was like the american version.

Don't worry about your english, it's better than most of our spanish.
