Are lightened pulleys and flywheel as good as people say? Or is it just another one of those things that are highly over rated? If it's possible to make the engine rev more freely and get up to higher revs easier then I can't see there being a problem. I actually prefer peaky engines, but I just don't want to end up losing all the low end torque/power and having something that's completely useless at low revs. But on the other hand, getting off from 1st gear doesn't take long and once you're up to speed you're only a downshift away from being in the powerband. If I was to go much further than just the usual rolla mani/air filter... full exhaust system exhaust manifold lightweight pulleys & flywheel thinner head gasket ported head maybe 5EFHE cams and maybe 6 speed box and possibly emanage blue? I'd hope it would end up having a good amount of usable power, but as not many people have done much with the 4EFE it's hard to know wether it's going to turn out to be rubbish or not. I know it's alot of work for a 4EFE but I plan to go for a GT in the future so I could probably re-use most of it, the cams, head, emanage, pulleys...
