    I have a 1986 chrysler laser 2.2 turbo. I'm planning to put a 1992 Chrysler lebaron 2.5 turbo head and turbo assembly on my 2.2. I know that the 2.5 head is crossdrilled and my 2.2 block is not. Is this possible and what head gasket do I use

    Because the block is not drilled it won't matter which head gasket you use as there will be no flow at those 'newer' holes.

    Just be sure to use the 'Mopar Performance' or better head gasket.

    i checked my local mopar dealership. They stated that the part number for the head gasket was obsolete. I'm having a heck of a time removing the intake and exhaust manifolds on my 2.5 turbo head. I would like to have a valve job done on the head before installation. I'm worried that a valve job may make the engine burn oil. The 2.2 turbo(1986) has 96,000 miles on it.

    5281064AB is the most recent number I have seen, have you tried it??

    Curious if you are going to run the Mitsu turbo on your 1986.

    Thanks

    I'm not sure. How hard is it to adapt the 1986 turbo?? Also the throttle body will need to be adapted. The car is suppose to be a winter project, but my sons audi is in the shop and he's driving my 2003 ram.

    A common up grade is to use the 1988 and newer Mitsu turbo and intake manifold.

    This converts the system from draw through to blow through.

    The reason many do this is its easy to intercool if desired.

    The Mitsu turbo isn't really suitable as a draw through due to the lack of a carbon seal.

    A draw through turbo is subjected to Engine vacuum and must have a carbon seal to prevent oil ingesting.

    A blow through isn't subject to Engine vacuum so doesn't need a carbon seal.

    Garrett Turbos come with or will accept a carbon seal but Mitsu's don't.

    Thanks

    I have a entire head, turbo intake and exhaust off a 1991 lebaron 2.5 turbo. I was thinking off using the turbo, intake and exhaust on my 1986 chrysler laser 2.2. Does this up grade increase the performance much?

    Not really as the Mitsu turbo is smaller than the Garrett.

    Its fast spooling for better off the line acceleration, especially with an automatic, but runs out of breath sooner.

    1988 was the only year that paired a Mitsu with a 2.2

    All 2.5 Turbo's got the smaller Mitsu, a step backwards performance wise.

    All T-II's got the Garrett and it was equal to the 1987 and older draw through turbos power wise.

    Most who change to the newer blow through intake retain the Garrett turbo.

    The main feature of the blow through is ease of intercooling.

    Its a lot of bother with little things changing to the newer intake.

    The cylinder heads were the same performance wise from 1986 and newer.

    No benefit to the newer head unless your older one is cracked etc.

    Newer one is roller cam, no real benefit other than probably less worn than the 1986 slider cam.

    Thanks
