whats the cheapest internally wastegated kit for a d series
You can let it vent open or recirculate it, it's up to you. Recirculating it isn't that difficult.cuz the dump pipe going back into the downpipe would be hard to do. is it better to have it go out into the air or back into the exhaust
Yescant you still adjust boost with an internal waste gate??
no just a difference in pollution (depending on whether you have a cat converter or not). letting it vent in your engine bay will also make your engine bay dirty faster. at the very least i would make a dump tube that redirects it out of the engine bay if its hard to get to any part (before the cat if you have one) of your exhaust system.is there any difference in performance?
They vary, I sent you a PMhow much are your downpipes?
