    turbo boost

    For 350-400whp 57trim ct-26 upgrade is probably the most available and probably the cheapest. I personally like a sp61 turbo which will give you over 400whp with supporting mods. The point is if you put the bigger maf on without the 550 injectors you will run way to lean.

    turbo boost

    The % increase from the stock maf to the lexus maf is about the same % increase from 440's to 550's. The piggyback is just to have more control of the fuel so that tune to more optimal air fuel ratios thats why I said you need a wideband.

    Differential Differences..

    spin the driveshaft exactly one time and see how many times the wheel spins. Its a lot easy easier to do this with diff outside car not connected to the driveshaft and axles.

    turbo boost

    Do not attempt to use the lexus afm without 550 injectors and some kind of piggyback controller. The intercooler will help a little because of the higher efficiency of the intercooler which will disapate the heat better. So far as turbos goes what power level do you want to attain? A wideband is...

    MkIV brakes on MkIII

    Can you put MK!V brakes on a MKIII? I've heard that the caliper bolt pattern is exactly the same you just have to space the caliper out so that the disc is centered is this true? If so is there more to it than just that?

    turbo boost

    Anything above 15psi you'll be well out of its efficiency you'll be losing turbo life and gaining heat. Personally I wouldn't take it above 12psi.

    Differential Differences..

    I would go with a 3.90 kind a happy medium, it all depends what your going to do with the car. Also a factor is tire diameter if you are going to make your car a drag car and running a larger diameter tire.

    fuel upgrade

    I would for sure run the lexus maf from there its more what your more comfortable tuning. Depending on your air fuel ratio you might not have to tune at all.

    Which radiator to buy
