I reckon 140 to 160 banans easy.

Not sure about the piston mod. All it would do is reduce the CR allowing you to run MORE boost.

no way i was expecting bout 110bhp very tops. even more inspired to get my finger out now. i think ill have the pistons done for an extra 50 quid. mite be able to run a bit more boost through it. also ive seen for sale hi boost carb needles. and hi boost carb springs. i guess i need them so is the gearbox going go boom after a short time.

Don't bother with the high boost needle, but the spring is worth having.

Once running get it to a rolling road where the needle can be properly profiled.

As you are local (to me anyway ish) I suggest using Mikeaniacs in Congleton.

You'll find their contact info in the rolling road thread on this forum.

Skimmed pistons equals crappy combustion. Less CR but the ability to run high boost remain the same. Loose-loose situation.

Sold the turbo and seeing what the C20XE can do!

Near Lincoln

i wouldnt recommend it at all. better to go for bigger chambers or bigger dished pistons to run more boost *smiley*
