there is no magic answer to this question. there a lot of variables involved. you need to do atleast a compression test on the motor. to see if it is holding stock compression at the least.

Judging by your posts no I don't think you have the technical experience.

I was about to say the same thing.


OP you need to do a lot of reading. Your questions aren't going to be answered in here because the information is already available to you.

Like the other members stated a compression test will let you you know how healthy the motor is.

If your not willing to put the time in understanding forced induction and knowing what happens to a naturally-aspirated motor when you give it booost then it's not for you.

I don't suggest doing it unless you have friends who can assist you.

It can get expensive when things go bad or your motor throws a rod from over-boost, locks up from oil starvation, or improper tune.

Hopefully we made the point clear.

You need to talk to Performance Shop mainly Dezod, Ptuning, or Descendant.

They are the best to talk too because they know the 2azfe inside and out.

dont forget about a leak down test. theres a lot more than just slappin a snail on these cars and boosting. first off, these motors will hold up to about 350hp safely with an excellent tune. anymore than that ur askin for trouble. do alot of research. heres a basic rundown of what ur gonna need. fyi, if u dont plan on tuning the car and getting larger injectors DO NOT exceed 5psi. the ecu CANNOT compensate for boost.
so heres the list based for 9psi (not including ur turbo setup which if u buy a dezod or ptuning kit is pretty much bolt on)
1) 550cc injectors
2) aem fic or greddy emanage ultimate (suggest plug n play harness)
3) a good tuner~ VERY IMPORTANT!!!
4) at least a 255lph walboro fuel pump
5) minimal basic automotive skills (not necessarily to diagnose but mainly to change parts successfully without issues)
6) lot and lots and lots of research (most of the guys on here will be more than happy to guide u in the right direction, just make sure theyre reputible)

and last but not least, this should be the most important...use quality parts, and not ebay knock offs!!! somethings may be ok but make sure its not any components like turbo, wastegates, bov's, manifolds etc... better to get it done right the first time with quality parts. ull get better fitment results, and longevity out of em.

we are telling you the steps you need to take to boost your car. i don't know if you are just waiting for someone to tell you what you want to hear but it's not going to happen. unless you know how to do what we've suggested or know someone who does. i'm pretty sure most of us would advise you NOT to boost your car due to your lack of mechanical experience and if somthing were to go wrong you'd be in a world of hurt with no one to fix it unless you have a fat wallet.

with a proper tune yes the tc can handle a decent amount of boost. there is always room for error though. it's not like you just slap the turbo kit on and go. there are other aspects involved.

so in answer to your ultimate question of weather you should boost your car i would say no. you should not boost your car unless you have a lot of extra money laying around.

if ur not mechanically inclined and dont have a deep wallet, than i strongly suggest that u purchase a car that is boosted from the factory. in turn minor bolt ons will give u decent power gains and u wont have to worry as much. the tc's can be tempermental and there has been days when i said that the turbo was comin off, but i stuck with it and im happy with the outcome. but as i stated before, it sounds like and evo or something along those lines will be best for u. a car thats n/a from the factory needs more attention than a car thats boosted from the factory. this is where some mechanical knowledge comes into play. plus, the average mom&pop repair shop will also have trouble diagnosing any issues u may accrue over time. the best of luck to ya on either which way u decide to go.

there is now way for us to answer this question because you havent preformed any of the steps we've said. now had you come to us and said "hey these are the results from my compression test is my motor still good?" then we could help you.

it's like cooking man. you wouldnt ask anyone over the internet if your food is cooked or raw.

Not to be harsh, but to be honest Id either become best friends with someone local who has a pretty thorough mechanical knowledge and is willing to help you, or take it to someone like Dezod. It just doesnt appear that you have the background or knowledge to take this on alone. You can learn alot from reading around on this forum, but its gunna be hard without someone there to help you.

As for my recommendations, like others said, first do a compression test and see what kind of shape the motor is in. If its good, a safe max power level on pump gas would be around ~300whp. Keep in mind, you need a good tuner if you want it to make good power and last.

He doesn't get it guys.. he keeps asking questions after questions of the same things that cannot be answered merely in a post or two.
