Hi there has any one upgraded threre ignition using a msd 7020 or hks twinpower or sim and wat were the results i vaquely remember reading a post along time ago but cant find it now . Thanx
Manny on these forums has the TwinPower in his 1JZ Soarer. Results were rather good from memory. I think it only comes into usefulness over 250rwkw though. I'm considering the upgrade shortly.
