I got recovered back from the M3 last monday, with head gaskets gone. Now in the shed i have my old engine under wraps, its a wrx lump so may not be a closed deck, i have an engineering background and a full cnc engineering workshop at my fingertips, along with billets of aircraft spec alloy, i am pondering with the idea of a rebuild, my idea is to strip the block, rebore and hone cylinders, get the crank crossdrilled and reground, lighten flywheel, then send away for balancing, fit new pistons, rods, main and end shells, rcm oil pump, do i polish and port the wrx heads, recut valves, replace springs and cams as finding v4 ones can be hard and expensive, remake pulleys out of alloy, clean and paint up everything else, then 550 injectors, turbo, sling it in then remap... i will have a budget of 2500/3000, is it feasable../..possible, plus i will have the satisfaction of knowing i done it.
i would appreciate any ideas comments, or links to rebore limits, bore sizes skim limits on heads, head gasket sizes etc.
its off the road for a while anyway......
