yeah, my gains I think will be a bit different to typical gains I would think a fair amount but can't really guess a number. The basics are that most people can make close to 300rwkw through an auto with stock cams and a decent single turbo setup. If you want much more than that, it is a good idea to upgrade the cams and valve train to allow more air at higher revs and also be able to rev the engine higher which will also allow it to make more power. I can't remember where I found it, but there is a graph of different cams for the 2jz. It is for HKS ones but you get the idea, has stock cams, 256's, 264's and 272's. The 256's and 264's seems to bring the power on a bit quicker and make more power in the top end whereas the 272's had similar low down power to stock cams but more top end than all other cam setups. This is HKS ones which are 9.0mm lift for 256 and 264 and 9.3mm and 9.0mm for 272's (exh and inl) are different. The ones I am looking at are the 272's with 9.1mm lift or possibly the 268/276 9.5mm and 10mm lift as I am now thinking of getting the valve springs and retainers as well and may as well go all out Going to ask Manny about interference on the 1jz engine now.
