is there any difference between the externaly gated and the pro s (internally) in terms on ps rating, also what other mods did steve do to his rb25 to make 320rwkw and was it on pump fuel?? if so im looking very forward to my dyno run in a few weeks. if pos could you get me all the mods that steve did to his rb25 so i can compare it with mine, that would be great if you could. did he have stanard internals or forged ect ect. It was in a r33 i figure i've done the conversion into my r32, counting down the days untill its back on the road, lost my lisence for 12 months only got two and a half to go given me plenty of time to go sick on my beast.
