With the 2.3l and slightly bigger BB turbo I make just under 500hp (could be over with some bigger cams and pushing boost harder but...) and I have a wider power band that starts earlier than stock turbo/block.
Also consider national style courses and nationals are most definitely faster than your local stuff. Higher average speed means less time/risk in lag.

I'm hoping that with the twinscroll 7163 and 10.5:1 compression I'll have a much better powerband and response than a stock turbo 2.0 setup.
Back in 2013 when I was running a 2.3 with a ported JB BBK Full, I was hitting peak boost (33.5psi) at 3300ish, and making peak torque (440wtq on a Mustang) at about 3800 IIRC. You could never get that out of a stock turbo 2.0 setup, and I ran the stock turbo on a 2.3, but it's just not enough turbo. I had peak torque at 3900, and peak power around 5000, falling off drastically beyond that.

It should come on a little quicker than this. Should be a good setup for you.

Don't mind me, i'm just here collecting a trophy nearly every event on a near stock X in SM and ASP. This really opened up my eyes as far as how my local competition stacks up to other regions though lol. On a side note, i love the X compared to my old 8 on course. Cant wait to see what it does this year dropping 400lbs and taking full advantage of the SM rules.

TRE has those. I had to buy a spider gear set from Jon when he rebuilt my trans. He found some cracks on them with the magnaflux machine.
