    Do not waste your money or your time!

    There are so many parts you will need to do this correctly, you can buy a used 4V cheaper.

    You will need
    Cylinder heads and cams
    timing cover and secondary cover and chains
    4V intake to match heads
    twin 57mm throttle body for the 4V
    24/lb hr injectors
    4V pistons as the cr is different now with those heads
    Forged crank from a 4V being you regularly rev to 6800 unlike the 2V crank
    8 bolt Flywheel because the Cobra crank is an 8 bolt and yours is a 6 bolt
    Alternator
    coolant crossover tube
    a tune
    Modify the harness and I am sure I am missing a few things here.

    This list is 4-5 grand and a 4V motor can be had for less.

    Yup, he's right....better off buying a used 4V engine for half that price plus you get an aluminum Teksid block and forged crank.

    If I recall the 2v for 96-98 is 9.0:1 verse the 4v's 9.85:1

    My motor is going to shit it burns oil pretty decently misses all over the place and one cylinder has about 5 psi of compression :mad: . So Iam just exploring all the possibility's right now. If anyone has any cheap suggestions Im open to all ideas.

    you could always get a 4v and drop it in!

    I work at a small engine repair shop and I do this stuff alot. about the cheap is't thing to do is have the block honed out, then rebuild it with your existing rotating assembly and just replace the rings, and bearings and little stuff like that. that is off course if you can do it yourself. If you can't do it your self then I don't know what to tell you.

    I think the next thing I'd do is take this oppertunity to upgrade. think of it as a discount because even the cheap way is gonna cost some money so why not trow some more down and save yourself in the long run. If you plan to upgrade in the future.

    Just my 2 cents 8)

    That seems to be the best option at this point. I kinda just want to fix the problems I have now as well as build for the future, at some point I plan on some sort of forced induction... but thats about 4 grand down the road. Thats what I miss about my DSM, cheap speed.

    you would have about the same C/R with 4V heads on a NPI shortblock...the Combusters Chambers on NPI heads are about the same size as 4V heads.

    If you really want cheap, just look around on the forums....Some people pretty muchgive NON pi engines away.

    if you deside to drop in that 4v i got the engine harness, power harness, computer harness, and the 97 cobra computer that has been retuned, all you have to do is get a tune on it. :O)
