MHI FP Red on stock block/head/cams?
Are you still on the 255 fuel pump? I can't imagine the Red making much more power up top with it than the HTA71. I think my 255 ran out right around 480 or so.

Alright guys, to update this thread.
I went with the HTA71, then quickly decided it wasn't what I was looking for, that big top end. Now I got the HTZ Red on, and I'm loving it! Definitely has some lag, but nothing to complain about. It pulls crazy hard once it spools up. Now my question is, how much boost is safe to run up top? I can tell that it will hold whatever boost you want it to. I'm on stock headstuds, wondering if it would be stupid to hold 32psi out the top? Need some opinions. I know if I encounter knock I'm asking for lifted head. Thinking about sticking with 30 to stay "safe"

Boost doesn't lift the head. Timing does.

I'm self tuning and looking at getting some dyno time in to get some MBT sweeps in, but using VD and flat road has actually worked really well at showing power increase per degree timing added. 500-525 stock head studs as well?

Needed to hear that. I'm just gonna stay on the conservative side, being how conservative with the Red makes a ton of power. Im enjoying more how it doesnt want to spool the second my toe touches the pedal. I can calmly cruise around town with ease, and hit the gas and boost when I want it to.

That takes skill! Lol I swear that HTA71 spooled faster than the stock turbo. Or maybe it just made its presence known more easily than the stock one. I definitely see why you love that thing so much. Red just suits me better with my driving style and what I'm after, highway pulls etc.

The MHI Red is well balanced for these cars for street/track/fun. Going with the 450 pump and a proper rewire should allow you to max your injectors out and make around 470-500whp or so. You could also go with 1650/1700's if you wanted to make over 500whp.
If you are self tuning , try to keep it on the conservative side. You could also rent out a dyno for an hour and really dial the car in if you have a good understanding of ecuflash and tuning concepts.
