AMD’sTheBest should chime in then. He had a very well built turbo probe way back.
A single would be way easier and cheaper. Not even talking the fab work… just parts. 2 turbos, 2 wastegates, 2 down pipes, 2 flex sections for the down pipes, Y pipe for the exhaust, 2 into 1 intercooler, or a Y pipe for the charge, twice the AN and stainless braided lines for oil, etc. its a long list.
Price wise I cant put a $ amount on anything yet, I need to see the truck, and really start there to do it right. But this would be helpfull:
Cheapest to most expensive:
-Stock iron manifolds, (if they are symmetrical) swap left to right and face them forward. Stainless crossover pipe to a 2-1 merge, to a turbo flange where ever it physically fits and looks good. Single turbo, simple FMIC and charge pipe setup. wastegate dumped and make a down pipe and exhaust from there. If they arent symmetrical, I can put the crossover pipe under the truck run it forward and up to the turbo, where ever we can put it.
Aftermarket tubular headers, like JBA, Hedman, etc, and do the above.
I make headers, and do the above.
Not saying twins cant be done, but its a whole new ball game and a totally different beast. Instead of twins, i would put that $1500+ in the bottom end of the motor instead of another turbo, wastegate, oil lines, etc.
like i said twins are a pipe dream. i dont think the stock cast iron ones are symmetrical, but i cant check because the truck’s at my dad’s house in PA. Anyways, im not trying to go racing, just have a fun little truck that can suprise a few ricers.
