Hi,
I have got 2 GTR33 with Trust T88, It produces 455 awkw but they are very laggy for tracks. I have taken one of the T88 off with waste gate, screamer pipe , heat seal rapped exhaust, manifold and all the bolts and nuts. I fitted a pair of 2530. down to 355awkw but it is more usable on the curcuits.
Will you be interested for a swap.Where are you located? I am in Mordialloc , Melbourne S/E Vic. 3195. Mobile 0433559972
