So after 6+ months of chasing phantom knock, and now today my mechanic discovering chunks of metal in my sump... it's time to bite the bullet and put in a new engine.
I have the option of buying a built, complete motor (came out of another car, with only 20,000kms) - which will be fully checked over and new big end bearings fitted (just as a precaution). The engine consists of:
EJ255 bottom end with Manley rods, Mahle pistons, ACL race bearings, Cosworth oil pump. The heads were overhauled and have Cosworth valve springs and head gaskets, ARP headstuds and case bolts.
Existing mods are Blouch TD05 18g, 3" TCP turbo back exhaust, Process west CAI and TMIC, 3-port boost solenoid, Kobe silicon turbo intake pipe, oil catch cans, DW65c fuel pump, Killer B oil pickup (to go in).
I have stock 550cc injectors, stock blow off valve, stock fuel pressure regulator. Should I replace any of these with something better? De-cap the injectors or replace with 1000cc's?
I guess it wouldn't hurt to replace the water pump and timing belt before the engine goes in. Anything else? It's been suggested I put in braided oil lines just to make sure there are no more chunks of metal stuck somewhere in the oil system.
Any huge benefit in Killer B Sump and baffles?
