A few questions where do i start.
Turbo Mini Forums

£68 bargain !!!!!!!!!!!

Don't know about the box, but a de-beaked head will be fine.

Whoever built this engine obviously wanted a good low compression ratio. Work this out first before you get anything skimmed.

All 1275 cranks are the same size as far as the primary gear goes, so no worries there, read this http://www.turbominis.co.uk/forums/index.php?p=vt&tid=4724

Its the gearbos nose bearing that is bigger on the turbo. But because it cost so much ost people use the standard item (with the apropriate flywheel housing) and have no trouble.

As a final tip, try breaking your questions down into easy to read nuggets, uit was hard to pick out exactly what you were asking, which is why I suspect that you have so few replies.

Cheers thanks for the info,dont know who built the engine but on one of the core plugs it has a garantee void if removed on it so probably someone decent.The gearboxes,just wondered if they would suit my application and maybe could swap the diffs for a better ratio.again many thanks!!!!
