Woo hoo, thanks to all the help from SAU
Manifold problem turned out to be the first stud, smashed the sh|t out of it with the hammer and eventually worked the manifold on. Then it sat there till i got off my arse and borrowed a torque wrench lol. Today i cracked at it and to my surpise had it actually running. Had some issues with air pockets and what not, sorted that out and took it for a lap round the block. Coming straight out of the turbo, sounded farken crazy. Boosted up to .45 bar, seemed nice. Running rich as all fark though. Get dump pipe made up this weekend hopefully then clutch in, then off to tuners where i'll install my injectors and z32 in his car park then roll er up on the dyno. Ooh yeah, can't wait. Will chuck some pics up soon.
