Both are WAY too big for stock location. While you might be able to get it/them to fit, you'd be losing out on a huge amount of power and spool by clinging to the inefficient stock location.

While I respect your commitment to stock appearance, you are absolutely wasting your time with this pursuit.

If you want to stay stock location, then stick with a <30r sized turbo. If you want anything bigger than that, then go rotated, you will be wasting your time by sticking with stock location on a turbo of FP red/black size.

I just dyno'd 490hp 492tq on a Mustang dyno with a FP Black. I too wanted to keep stock location for my own reasons. This was on E85 at 27psi. Ive had nothing but good luck with FP products. Upgraded from the Green and love the Black. Your limited with your stock heads going with a Red or Black, that was my problem. Good luck with your choice bud, you'll be happy with either one.

I have the fp red. I gave it a conservative 360whp (delta dash road dyno) on pump 93 octane just wanting a quick but reliable car. So far, no problems. I have not tried to crank it up with better fuel. I have a mbc set at peak 22psi.

Good luck.

Depending on fuel you may be limited with your setup. You already have the built block so get the Black and push it.

The black is such a waste IMO unless you absolutely NEED to stay stock location. I mean 490whp on a 68 lb/min turbo on E85? Those are pump gas numbers. A turbo that big should be hitting well over 600whp on E85, but it just can't because the restrictive turbo inlet/intake and tiny hotside are holding it back. If you're looking for that kind of power, then stop *****-footing around and go rotated. The ATP 35R fits into the exact same category.

Completely true on the restrictive intake quote, not debating that at all. I wanted to still look stock appearing, not have to change downpipe and any other piping and I got a great deal on everything. Some people take different paths to get to their goals and some learn things the hard way. From what I know now Ill probably go rotated in the future once this turbo goes. For now it does what I need and I have no complaints. Good info for the OP "suicidal"

I love my red, but eggroll is right, if you have darton sleeves, why bother with inefficient stock location turbo's and go with a rotated GTX35R, decent spool with even better top end.

Final tune on 93 or e85? you'll need a bigger pump/injector if going e85.

good luck, cheers.

I decided to up the heads with a full gsc valvetrain cams are stock but I did that so I wouldn't beat the **** out of that new rpm range and I've considered the gtx 35 with the rotated setup when I come Into money
