It's a 2010, has paddle shifters. Has stage3 dinan software, has bigger intercooler, oil cooler, cold air intake and axle back exhaust all dinan. Vrsf catless downpipes paired with CPE non restrictive midpipes. Looking to add some mods for future pure turbos upgrade. Need to know what inlets pair well with my cold air intake. What else is needed?

First things first. What is your end goal? Are you interested in times or dynos?

If you have the Dinan CAI i would sell it and get something else. Not that its bad, but selling that intake could likely pay for the majority of things you need to do for the PS2 turbos.

Start with fueling and inlets you can pick any since they all have the same intake tube diameter for the intakes side. I use the VTT OEM location inlets since i didnt want to relocate my coolant tank.

Any 2" inlet should work fine for Pure St 2's. They'll work fine with stockers too, just gotta tighten em down good on snout. If you're future includes a turbo upgrade, I suggest a fuel pump upgrade, St 2 for moderate E85, 3 for full E85. A step further would be PI which usually accompanies Stage 3 pumps when people want full E85.

I'm interested in a sound running car. Wasn't aware of dinan software limitations when I first got it yrs ago. But from my understanding the jb4 back end I think is will pretty much piggy of that. As for gas I'll most likely be running 93 with some 112. Have read that'll I'll need to upgrade fuel pump for more than 550whp but I don't need more than that. Right now I'm getting ready for PS2 turbos.
