February 17, 201214 yr has anyone out there borred a 2.2 up to a 2.5 it look very close was going to bore one today and c whats left looks close to a .50 over 2.2 piston i have set my boring bar just for doing subaru engines.
February 22, 201214 yr Author i did it and looks good a bitt thin around the barrel but will work for race engine now we plane the bugger down a bitt and get a short stroke 2.3 out of it or phase two rods and make a stroker 2.5 out of it i will biuld it and run it very hard c if it fails
February 22, 201214 yr Hey, Got a pic? If you look over at NASIOC you will find examples of split bores on an open deck block. Or did you use a closed deck? Doug
February 23, 201214 yr Well, what kind of race engine? Mud dragster? Quarter mile at a time you can do a full block fill. Concrete even, if you want. Doug
February 23, 201214 yr Author thiss one is just for experament porposess i like the long stroke engine for mud dragster i biuld the engines for my group of subaru buddys to wail on best wat to test them out i have biult my own subaru engine machine shop here and do all my own borring and planing in house i have probly ten or 15 ej 2.2 and 2.5 cores to play with whanted to know who else plays around with the enternals of theese engines
February 23, 201214 yr the ej22t closed deck block would be the best one for this type of stuff. bore to a 2.35 or so. boost to 30psi get a stronger gearset to handle it grin.
February 24, 201214 yr Author thoose blocks are very hard to find up here i get a 1000$ just for a short block i bet it could be bored but whould be a waste of a rare block i only have one and is mint we whant realy low budget moters the bored 2.2 to 2.5 engine cost under a 100 $ to biuld for me right down to its reused mains and head gaskets remember short life race moter if we get a week its doing realy good most are just in race buggys for are ice race track
