    Forged rx1 engine. How far can I push it?

    Well guys I ended up going with a 3071 and adding an msd mc-4 ignition setup. We will see how she does as soon as we get some ice for tuning.

    Can anyone identify these connecting rods? Also does anyone know torque specs for the 10mm chromoly head studs?

    That’s reassuring too hear. I’m going too be in the 450-550hp range.

    Forged rx1 engine. How far can I push it?

    What size turbo do you recommend? I was looking at a billet wheel ball bearing gt2871 that says it’s good for up to 550hp. I would like to keep spool time down as well since the sled sees 1,000’ radar runs along with 660’ ice drags. Would a gt3076 be a better option?

    Forged rx1 engine. How far can I push it?

    Hey everyone. I had a great year racing my turbo rx1 with 3 wins and a second place. It’s time to go faster. It’s currently a stock engine with a head shim running a garret 2560 at 20# and the turbo is maxed out. I’m looking at putting in forged rods and some forged low compression pistons...
