Just bought a LS/VTEC with a full turbo kit and quite a few extra parts and planning on dropping it into my EK Coupe. B18c1 head B18B1 block. The guy I bought I from said it made around 325hp (not sure if crank, whp, or bhp) on 8 psi of boost. I want to up the boost to around 12 psi and shoot for 350-425 hp. Basically I need some advice on some budget friendly but also reliable pistons/rods. I saw a guy selling some Nippon High Performance pistons brand new for $100 but they’re for a B18C5, would these work? Also possibly looking to get new valve sets while also staying budget friendly. I am willing to sacrifice power for reliability and budget, since you really can only get 2 of the 3.

 

LS eagle rods W/ arp studs and 10.0cp carillo, arias, or mahale whichever forged pistons with engine management and knowledgeable tuner. Don’t go nippon with those power if your wanting for reliability.

Valves I would go with ferrea valves.

type r are high compression pistons I wouldn’t go that high for your power goals if your boosting.
10.0 compression will be perfect for boost and you wouldn’t need much boost to reach your goal. Also taking into account ls rods you have to use will be a couple mm longer stoke than gsr rods so good torque and power across the whole rpm band.
