2) T34.48- with 360° bearing. Turbo was brand new, non-exchange direct replacement for the T25, I bought mine from Ian@Racetek, not sure what they are now but very reasonable.£700ish

3) Water pipes to fit the T34, the T25 ones will not fit as they are smaller. Bout £20 second hand off a 4x4 saff or big turbo escort.

4) Bosch 023 intank fuel pump, good foir 500ish BHP, either from Boschman off here or Matt lewis, don't need the fitting kit is a waste of time, about £85-100

5) set of bigger injectors, 55lbs at the moment might change.
