I'm putting a vg30et into an older Datsun and the firewall is not a barrier (will be fabricating all this. The stock exhaust elbow takes a quick 90-deg bend straight down, and the stock downpipe turns back to horizontal.
My car could definetely accomodate a straighter shot, with all the "free" benefits of reduced exhaust restriction.
The stock exhuast elbow is cast, and of course contains the internal wastegate/flapper. These are the two main barriers.
Would welding up some heavy 3" tubing to a flange fit for the exhaust housing- then adding an external wastegate be possible, or am I missing something?
I think the answer is "nobody's ever tried it because the stock setup is a good fit in the z31" - but I was wondering if anyone has ever tried to improve this part. (Like the many excellent and creative improvements I've seen over the factory "s" bend intake pipe.
