FAST 102 on LS1?
I laughed because it was a random number... Not 1200... Not 1300... But 1250hp.
For no budget that's an extremely low number. You can make over 1000 with a 347 and stock 317 heads stock ls6 intake stock throttle body and a baby cam. I don't consider that a no budget build... That's a whopping 400-500$ in the complete top end and stock crank.

I would say don't put the Fast 102 on the car until you have your cam and heads install. You're going to need (or it would be in your best interest to get) a tune JUST for the new intake manifold. I would say get your heads and cam combo down then get the Fast on there after everything has been installed.
Get it tuned once lol. I have over a thousand dollars on the dyno just for tuning which could've easily been avoided had I waited to install everything at once.

what rails are you guys having problems with?
I got the FAST LS2 style billet rails and FAST 36lber ls1 style injectors. Needed to use the included spacers and larger o-rings that came with it. For added insurance I also threw on the LS2 injector clips as well. Without them on, I noticed it's possible to seat the injectors into the rail at a position that some seem to think is too far and causes leaks. I actually had to lift the rail up off the injectors a bit to be able to install the clips. Might be something to check if you're running the billet style.

I bought take-off LS2 rails from Scoggin Dickey. Same for the LS2 waterpump.
Don't know if they still have them... but they are pulled off the LS2 crate motors and sold pretty cheap. So brand new GM parts.

Jake, would you mind PM'ing me everything I'll need to swap over to a 102/102 setup? I want to do like you did and use stock LS2 rails. I guess I'll also need adapters for my Accel injectors in order for them to be compatable with the LS2 rails.
Let me update this since I never saw this until I installed it:
You need to go buy about 24" of 1/2" hose for the brake booster (stock isn't long enough, because the nipple off the intake flares straight back and not off to the driver's side like GM or FAST 92). And you need to get a clip for the MAP sensor if you don't relocate to the front. Otherwise, it will hit the firewall and you have to turn it 180 degrees to fit, which makes the hold down screw in the wrong place. But a screw-down clip, like that used by an electrician to hold wiring up along drywall works. (And I don't recommend relocating to the front - you get better readings from the LS1 sensor in the rear.)
The FAST 92 is easier to install because it doesn't require new rails, a new WP (or grinding stock), and the brake booster vacuum line is angled back toward the brake booster (with the MAP on top - also a plus). Also, the 92mm TB is easier to tune from what I understand. But a good tuner should be able to make the 102 work. Of course, the 92 TB works on the 102... but only the FAST 92 and GM LS2 90 actually seal properly.
Nothing really that big of a deal. Just extra hassle you have to account for when you install the 102.

I have stock brake booster hose.. Map sensor fits.. Ground stock water pump.. New style 102 supposedly fixed part throttle and response tuning.
I run the fast 102 tb no issue.

I don't see how the brake hose fit... mine was at least 3" short before accounting for the extra inch or so that would be needed to route it coming in from the passenger side vs driver.
And the MAP sensor fits anyway you want on there... the problem is the wiring harness. When I plugged mine in, it was touching the firewall and was pushing the MAP crooked. That's bad juju with a hard rev. And I have Prothane motor mounts.

I had no problems with the brake booster hose. Fit just fine. Unless someone had put a different one on your car before at some point. And I ran the MAP sensor in the front so I didn't have to worry about jamming it into the fire wall
Who knows. I put a new line on there.
Also, make sure you have some M6 nuts to secure the stock throttle cable bracket to the manifold. If the manifold came with those, I didn't see it (though I swapped to some zinc plated M6 bolts as well since the stock bolts were discolored).
