Re: gp150 engine

Re: gp150 engine

Marktheskin, Points ignition or electronic? If its electronic, a lightened flywheel gives a surprising improvement with very little changes if any to carburation. Not the mid weight, the light one.

RB20 Repair Options?

I have a small block rb20. Stock size bore. I have an issue where the spigot on the cylinder is thin from factory and has warped pinching the piston at bdc.

Re: What is wrong with people?

I totally agree. Facebook has killed it.

Exhaust input 4 RB20 Needed

I have a modified rb20. 32 tm mikuni, 62mm crank, case weld and transfers opened up all the way on the cylinder. I currently have a jl mk4. It's the full race. I'm not a huge fan.
