Well think about this. There are two turbos on the VG30DETT for a reason, same thing with the MKIV GTE, RB26DETT, 13B etc. One turbo to handle low presure, one to handle high. Like someone said already, if you are planning on drag racing, a TT would be better... But if your planning on drag racing, you chose the wrong car anyways. Z's are best for handling the curves. I think a single turbo would be fun, one HUGE kick in would be something. But realistically... Would it fit? Where would it go? There is plenty of room down near the bottom of the bay, hence why they put the turbos down there. But where would the SINGLE fit? The exhaust manifolds would have to be the same length, same path's of flow, it would be hard as hell to fabricate. Has there been a kit made already? Never seen one. But other engines such as the RB, or GTE engine, inline engines, are easy to single turbo, because the engine only has one exhaust manifold. Anyone else have an opinion here? Peace foo's
