It also allows you to move your turbine flange around on your mani without worrying about effecting 1 or the other turbines exhaust flow.

IMO, the Supra Manifolds are rather restrictive considering the great port flow the 2JZ-GTE has. I thought about trying to improve on it by making a custom log mani and turning it into a parallel set-up with some modified stock turbos, but I just took a good look at my friend's in his garage last weekend and there is very little room for a better flowing manifold while using the rest of the stock hardware. I still have yet to do some calculations and measurements on it. Too bad I don't have a Supra to put it on if it works...
sil80drifter wrote:*sigh*... can I just superglue them to my headers and brag to people? I'll just say I'm not boosting, so the car feels stock... Btw, did you read the link? Is the supra setup similar in function? Manifolds look a little similar, so I'm wondering.
