Pretty much what the title states, i want to replace the turbo on my WRX, i think it is gone so i want to know what are my bolt on options. (Bolt on meaning a turbo that will literally bolt on without any further mods to a stock car)
Some background info:
I gave a buddy jump, i know i should have stayed within 2-3k rpm (from what ive read and been told), but i may (i definitely did) drop my foot and, if i recall correctly, revved to around 5500 maybe 6k (for literally 1sec to less than that). After that happened the car started making an awful grinding and knocking noise. Two different noises. One noise sound like metal knocking together the other noise sounds like something caught in the turbo. Two separate noises. At first i thought the bearings in the alternator ceased or something like that, after further testing the alternator seems good, battery maintains 13-14V (optima yellow-top). I will, however, do further testing to rule the alternator out completely. When i first start the car there is a knocking noise (sounds like metal on metal) only for a few seconds and then randomly after that. As for the other noise, that is heard when I rev past 3K there is a grind noise where I usually hear the turbo spool up (this is really for another thread though, any input on this though is appreciated). I was able to drive my car 2 miles without any problems as long as I stayed out of boost and didnt rev past 3K.
Anyway, so I am assuming the worst which is why I would love some input about options for changing the turbo. As it stands the car is completely stock. I just put in an order for a grimmspeed uppipe (the stock uppipe is still on, i never pulled it to see if it was catted or gutted) I plan on pulling the turbo out to take a better look at it. The car is an 02 WRX at 98K miles on the clock, it had 4 previous owners none of which I can contact to find out what was done to the car (as far as the uppipe and recalls go). I already check out my local subaru dealers, the OEM turbo goes for around 1200$. Ive been told im better off picking up a used one on the forums. Do I have any other options besides buying a used OEM turbo? Are there anyother aftermarket turbos that will bolt on without any other support mods (like injectors and such)? That is pretty much my bottom line, what are my bolt on options for a stock car?
All and any help would be greatly appreciated, After this post im going to hit google and continue using search on the forum. Im sure this question must have been asked before so I will keep on searching (its been probably 2hrs with no luck sofar).
Info about my car:
2002 MPB WRX, w/ 4EAT Tranny
My ultimate plan is full stage 2 with a turboback exhaust (cobb) w/ cobb AP and appropriate map.
98K miles on the clock.
As of now the car is parked up and will NOT be driven until i can get it on a lift, pull the turbo, inspect damage, and do more trouble shooting steps.
My brother and I will be pulling the turbo in a few days to check it out. This is why I want to prepare for the worst, so I am assuming the turbo is dead. Im looking into new turbos and possibly rebuild kits depending on what is wrong. This is pretty much my fault, and I know this and i have come to terms with this. With all the reading I did about this car prior to purchasing it, the uppipe should have been to first thing i checked and replaced after this car was in my hands. Due to going to school paying for school and working a part time job, i kept putting things off and kept saying soon soon, which is why im in the position i am in now, in any case input and feedback is greatly appreciated, ive always valued the word and advice from the members of this forum.
