    Sorry man, the D15Z1 is hopeless, and will never be fast. Had it pounded it replaced it.

    <_< This isnt the help i was really looking for, its all good saying that i should pound it, but i dont want to buy another car or engine for a swap, this car has been made for track use has a roll cage fitted and leda shocks, nsx calipers and prelude discs, bucket seats and a stripped interior and some carbon parts and light weight wheels, im just looking for a bit of fun tunning to run the car into the ground till it cant take no more and i was lookin to have a go at seeing wat was best, i know there isnt much to tune it with as with most D-series but i just want to experiment. for instance with the cat being on the exhaust header i was wondering if i was to change headers for a d series header that doesnt have a cat on it what gains would i get

    You may see something runnning no cat, you could maybe do a mini me, or bore and stroke it. You can turn it into something else, but I am just saying the gains aren't going to be worth it.

    Mini me is usaully putting a vtec sohc head on a non vtec block, I don't know what combo you could use for the D15Z1, since it is vtec-e, maybe a ESi vtec head since it wasn't quite as much of an economy motor, and you could get a different tranny, the VXi had a very economically geared tranny. Maybe a Si, ESi, I believe is the Europeon version of the US Si.

    i was thinking that an esi head would fit but i didnt know the VEi has smaller valves than any other with it still being a vtec car i would need/want a vtec head

    Thanks for all your help Richie :D
