    Well I`m still in process I`m sorting suspension out but I`ll will be looking into dropping engine very soon..

    My goal is 400bhp at minimum.. I`ll be looking at a bigger turbo and internals.. but wondered which is best way to go about it..

    My cars about 320 at present but 400 is my benchmark

    read tufftys thread is a good starting point
    engine internals essential and a decent budget for realistic power of this level, done properly

    GT3071 at least, bigger injectors than 550's, I run 630's but getting close to max duty cycle, large port head then maybe a SEM inlet and 75/80mm throttle body.

    Internals wise, rods is pretty much all you need unless you are up for rebuilding the entire engine... no need to go 2ltr stroker but would advise a head rebuild with supertech valves, springs and retainers.

    Last time I had mine on a dyno, it was producing 383bhp with a boost leak (was running just over 1 bar), a std (original) exhaust system and was over fuelling due to high EGT's.

    EGT issue is now sorted, I have a full 3" straight thorough exhaust and will be running 1.7bar once the new map has been loaded on... no idea what the power will be then but should be in the region of 400bhp...

    Have a read of my thread for some ideas but if you don't mind pushing the boat out a bit, try 483bhp from a similar setup on the Polo built by Badger Bill
