sr20det problems, need help asap!!!!

[silviakid2790]

so i went to pick my car up today from the people who are doing the swap cause it was supposed to be ready and i got there and we went to take the car out for a test drive and if you drive the car easy it runs perfect and smooth but as soon as you get on it and the turbo starts to spool up the car wont do anything it tachs out like its hitting the rev limiter or something, so i drove 2 hours to get my car and wasted a whole fucking day and had to drive 2 hours back and have nothing to show for it, any ideas of what this might be? any feedback would be appreciated, thanks

bump......come on guys i need help, ive heard alot of people say boost leak and some others have said ecu probs but idk, what you guys think?

[slim]

boost leak most likely

[johngriff]

Sounds like they installed a bad engine.

How much did you pay?

[fliprayzin240sx]

Could be a bad maf, o2, boost leak...etc etc....

[I_DID_SILVIA]

ohh i know what your talking about when you hit the gas it spools but at around 3700-4300 rpms it acts up right??? if you didnt change the fuel pump thats what it is....you gotta upgrade the fuel pump

[silviakid2790]

nah i dont gotta do that because i already have a walbro 255lph fuel pump, we think its a boost leak so they are gonna check it later on today

[drifting_changed_mylife]

check maf and engine grounds!!! thats what was wrong with my car
