Can anybody give me some advice ive recently bought a bent cam sr20, carried out a leak down test to find leaking valves and piston rings, so decided to rebuild the engine, ive scoursed some new valves and have decided to go with forged pistons and rods, but im unsure of which ones and and which sizes to choose for the pistons and crankshaft bearings, can anybody advise me on how to determine the correct size to buy? Thanks in advance
