    Come And Drive My Car!

    Is anyone free over the weekend who could have a look at my car? Its running like crap at the moment and I dont know what it is? Cant afford to let Vxl look at it at the mo and dont really trust them to find the problem anyway! I can come down to you if anyones got a spare hour or two sat afternoon? Really needs to be somone with the same engine (z20let).

    The problem I'm having:

    Complete lack of boost when put foot down. Turbo whistling/spooling loudly but not much power. Sounds like turbos ok just not getting the power in. Exhaust note (from milltek cat back) has changed since problem started a couple of days ago. It now sounds crap and louder. Does it sound like its something to do with the exhaust maybe? loose connection?

    Really need some advice asap guys hoping to have it sorted by sunday

    You might be pushed for someone to look this weekend mate, as most people will be getting their own cars ready for PVS on Sunday.

    Could be a few things.
    You say the turbo is whistling/spooling loudly, first off they are not very loud. So maybe if could be a boost leak, check on the hoses from the turbo to intercooler, then intercooler to top hat one maybe split.

    I doubt you would lose much power over a leak in the exhaust system.

    Air Flow meter?

    Worst off the turbo may have gone pop, look for oil around the turbo or while you are checking the boost pipes take off the bottom hose and see if there is any oil in the pipes

    Hope that helps as a starting point

    Hi mate cheers for reply. Figured people would prob be busy just wondered on the off chance if anyones local?

    Boost pipes: checked em this morning couldnt see any obvious splits etc

    Afm: could be... tried my mates tho and still had same problem. He says his isnt running well either tho so it could still be that.

    I'm pretty sure it is a leak somewhere i just cant ****ing find it !!

    If you can make it to Westerham at the end of the month I'm sure there's plenty of us that could have a quick peak over the car and give you a hand.

    Actually take the pipe work off. Its only needs to be a small hole tucked away out of sight that could cause the problem.
