old evo turbo is a good choice as it is small and spools up quick
just my 2 pence worth
and what clutch you going to go to with 300 bhp -- you are on a very special unit --basically a single plate 200mm6 paddle unit --by the time you make new flywheel and mod al the other bits you will be over £1000 for the clutch =flywheel assembly

That's a good point about the clutch, I totally forgot about that.
I used a 4 paddle Helix with the 'race' cover - which probably means hardly anything from the 'road' version, but hey ho. It was also 2nd hand.. so had already been used in some other turbo shed.
Anyway, It was slipping at 275bhp, so I had to turn the boost down. Gutted.
I started looking at options and like John has said, it became a costly nightmare. The lug drive things are mental money. There is nothing in the range of 250 to 300bhp or so, for clutches on these - that are still affordable.
I decided to get a new 6 paddle helix and new cover. If it slips, then I'll accept the fact, I shouldn't be so greedy and limit the boost accordingly. It's not rated for the torque, but no other cheapish cost effective solutions exist for where I am with the power.
Good luck George.
