Looking good mate, definatley a good base to work on. I know everythings temp, but have you seen the pontiac sunbird turbo manifolds on ebay.com? from the G20LET engine, might be worth a look.

[astra mk3 8vt]

they are hard as hell to get for the 8v engines ive seen a few the ones off the c20get are t2 flanges not t3 witch is what im running

what manifold/s did ya use m8 ? whats the turbo off ? and what did ya do to lower the compression?

im intrested in doing the turbo conversion on a 8v im running

That mount your using is no good what you need is one from a none aircon vectra that will give you better clearance for your turbo

manifold is a home made one mate but here is a link to the propper one im just waiting on funds to get one

http://cgi.ebay.com/ebaymotors/SPA-T...mZ320203257634

the turbo is a t3 with internal waste gate the compresion is standad 9.2 compresion i can get a way with this as im running standalone managment so it been mapped around it but to lower the c/r you can get the standad pistons mechened for about £50 or stick a set of let rods and pistons in it that will drop it down to 8.5.1 i couldnt do that as mine is a 1.8 and the block is not as tall but even on this c/r im running 13 psi and it will go more yet if you want more info on 8v turbos have a look on my mates site http://www.vaux-extreme.com/ im vecky 8vt on there
