    Hello all,

    I am from Australia and own a 4wd BPT powered Ford Laser which was released from the factory. Its basically a mazda GTX in a Ford Laser shell.

    I just thought i would answer some common misconceptions about the GTR motor. There is a of rubbish posted on the internet about these motors and as a result they are being flogged for an inflated value.

    Firstly I will cover the differences between the GTX and GTR motor:

    As many of you have said the turbo is different - VJ23 on the GTR and VJ20 on the GTX.
    The injectors are different - high flowing units on the GTR.
    The Valves on the GTR are sodium filled to help dissapate heat.
    The exhaust manifold is a better engineered design.
    The rods are rated ro 600hp.
    The Pistons are squeeze cast (not forged) and sligtly stronger than the stock GTX ones.

    That is where the differences end. The block is not web stiffened as has been reported. The cam durations are identical and all other components of the engine is IDENTICAL.

    If you get a stock GTX motor, replace the rods from the B6T motor which are rated to 600HP, drop in some decent forged pistons and utilise a decent size turbo running through a good front mount cooler you will have an engine that is just as reliable and producing far more power than a GTR unit. The only thing you will lack is sodium filled exhaust valves... whoopdy do.

    Come to fordlaser.com where we have discussed the topic at legnth. I hope this has cleared up any misconceptions you may have had.

    That's interesting, I wouldn't have thought that the rods from the B6T would be better than the rods on the GTX.

        for the first gens which is the weakest link the rods or the pistons, and at 300whp will the lx internals hold the power well, if not i might go find myself a b6t. So will 300whp be ok on stock.

          im pretty sure the stock internals of the first gen can hold up to 400hp. So you should be fine.

              The internals should be just fine at 300whp. After that, the tranny will probably go before the internals.......

              while you're out there, you might as well adjust your air/fuel ratio by smell... and your tire pressure by ride height

                I don't think the B6T rods are in production anymore. If you ask for them they'll give you Miata rods.

                  seems to me strong internals means dummy proof.

                  while weak internals means tunable.

                    or strong internal can mean going for all the power a 1.8l can make before the car says "F U" and locks you out.

                    I'm going for the lock out Bruce.

                      GTX, GTR, and N/A rods are great. Don't worry about them as the first thing to replace. Rod bolts, head studs, pistons, and turbo are the first things to replace when going for reliable power. Also the tranny could use some work above 300whp.
