I was thinking about a 2.5 short motor for my 99 turbo and using the 99 heads, ok ? My only concern is obviously the gearbox. What's my options? 6 speed , PPG, what costs and parts/options am I looking at here.
And will my diffs be ok or do people upgrade them purely for gearing rather than them being stronger ?.
The car won't be going over 400/400 but would like to know what's involved.
Am i better using wiseco 'drop in' pistons ?
So many questions , never mind the spiraling costs involved.
