Dont bother with the 32 Conversion lol.
Well its up to you.
You benefit more with the VR6 with Cams etc being a 12v, where the 32 being 24 has less room to play with plus with the engine already having the VVT set up.
Personally get the VR re-built and slap a charger on there and you will see fab arse figures.
10Psi plus, Power to weight ratio, just have a think.
Just finished helping my mates VR with a V1 Charger, had a 8PSi pulley set up, and achieved 1bar of boost which is not normal at all, I think it was 320hp and was still climbing.
