Well we sovled the misfire with a second hand coilpack and it looks like it's been an issue from the start as when we took off after fitting it she spun the wheels right through 2nd gear. We took a run of a measured quarter and did a 15.5 with a bogged down take off and i basically rolled through the last 40 meters, i am very confident that the car will run a 13 second pass no problem!

Dunno, we need a boost gauge, oil pressure gauge and can't get the speedo to function yet  :P

Does it have an internal regulator on the turbo, with the hose going from the compressor cover to the wastegate.

The completed car took a trip to Albury this weekend and promptly blew the diff which we had planned to take it easy on till we changed it out for a stronger unit.
I was thinking of either;
A series 3 Bluebird diff
An R31 diff or
See which borg warner centres from a ford are interchangable
A VL turbo diff

Not sure which way i am going to go yet, sure wish it had the irs end now!

Any live axle Falcon from XD to AU and live axle VK-VT Commodores have the Borg Warner 78 diff

They aren't too bad. With experience only in R31s and some live axle Fords they can develop a bit of diff whine from 80-100km/h. The LSD centres are useless though, I would choose a mini spool or an aftermarket centre if the cash was there.

There are a variety of centres available (KAAZ, Detroit locker etc) available for them too. With your 200B's set up I think a 78 series diff should be ok considering the amount of turbo Falcons, Skylines and VL Commos out there with them running 300+kw

Some good reading on these diffs:
