I wasnt figuring that in no.. DD performance should be excellent, and hwy driving. Turbos are more efficient for DD, but I just dont like spools time. Dont get me wrong, Im not knockin the install, it should be great! I just wouldnt add one because theyre kinda one sided. Thats my opinion, dont read in to it too much..lol.

you will want some back pressure with a turbo system. Especially when spooling up that T4. Good luck with the Kit! What fuel pump are you going to run?

With a 3.8 I don't think spool time is going to be too bad My Evo with a 20G and a 2.0 was pretty fast, having the extra two cylinders and almost twice the displacement will make a huge difference! I really thought about doing the turbo kit, but I went Sprintex for the small form factor and for where it puts down the power. I considered buying the ARP head bolts from the prodigy kit for extra insurance on my setup.

Thanks! I'll have to come down to Pompano to take you for a ride! I like the fishin over there better then here on the West coast of FL...

Unlike NA setups there is no back pressure needed on a turbo setup, so I went with the free flow muffler. Of course there will be some back pressure cuz that's life, but I want it minimzed so I can get that turbine spinning and make the most power possible. Also, I'm using the stock pump with a "Boost a Pump" device which is included in the 12 psi kit that adds juice to to pump when more fuel is needed based on boost levels so it doesn't lean out...

I agree, Prodigy's dyno shows 200 ft-lb of torque before 2000 RPM at the wheels

Compared to the stock torque number at the crank of 200 ft-lb max (LOL) and then it makes 400 ft-lb of torque at the wheels before 4000 RPM, so spooling wont be an issue

Well spooling "will" be an issue just because it's a turbo. SC will boost linearly with RPM. Turbos follow a sort of exponential growth leveling out at whatever psi they can get. So there is always "a" lag but I highly doubt it's going to get you in trouble. And if you have a auto, that is what brake boosting is for lol.

Default OEM tune sent off for 12 psi tune

Using the inTune I downloaded and sent off my current tune to be upgraded to a 12 psi tune, which I will need to have in hand before I start this project...
