I have a used ATS t-4 fully ported ex manifold for sale. No cracks and in good condition. Looking to get $500 out of it. Only ran for one season. I have $950 invested.
it will work on either one. Both will require making a custom intercooler pipe. And for the ex. you will just need a hx40 down pipe and a flange to connect to the ex housing, which i could get for you.
$2700 for the kit with the top pump (dmax)
$4200 for the kit with both pumps- plus will need a dodge core pump in return.
This set up flows a ton of fuel, the two pumps high pressure lines dont connect. The bottom pump goes to the rail like normal then the top pump has its own .125 hp line connecting to the rail in place of the fuel rail return.
