I have a 82 22r block and a 78 20r celica head. I know how to put it together, ive searched and read the threads. The 22r motor has a stock bottom end (bored 0.30 over) with less than 20k on it, weber 38, offenhauser dual plane intake manifold, dual valve springs, .515 lift cam, adjustable cam gear, racing distributor, MSD ignition and coil and wires, and a header going into 2.5" eshaust. All smog parts have been taken off and thrown away. The only vacuum lines are to the PCV and the brake booster.ANYWAYS...Im trying to decide if I should..Use the 22r head that was already on the motor and put bigger valves in it (it has stock size right now) and possibly polish the ports.orUse the 20r head I got off of the mentioned celica, get a 20r intake manifold, larger valves, and possibly polish the ports.It looks like the 22r head would flow way better than the 20r head. But maybe my eyes decieve me?I need opinions!! thanks people
i did research with same idea in mind and found with 20r there is pluses but with a nice port polished 22r u can get better then a 20r head but all comes down to is how do u want the power what rpms u want it at
has anybody tried Total Seal gapless piston rings? They are supposed to increase HP and torque because of its superior sealing of the combustion in the cylinder. Is it worth it to get some die grinder bits and polish the 20r ports? YES, especially the exhaust side, i would gasket match the exhaust ports to the header and where those little smog tubes are, remove the tubes tap the holes and install allen head plugsHere is my list of parts I need:Refurbished rocker arms Full perimeter crankshaft scraper --- 20r intake manifold --- gasket match to the headMain/Rod bearings ---- Clevite is bestGapless total seal piston rings ---- if you can get them at a good price but not worth alot more $New timing cover Full gasket set from toyota Flywheel boltsARP cylinder head studsmachine shop work: cylinder hone block/timing cover & cylinder head decked -- dont deck more than needed to get smoothmaybe install bigger valves ---------- use stock 22R valves and valve seats in the 20R head
with the 20r head on my 22r motor, will I be able to use 22r aluminum rocker arms? or do I have to have the 20r steel ones? I noticed the 22r/20r valves are different heights. This is the only part about putting this motor together Im not sure about. thanks for the help
I have run the C&A gapless rings in a supercharged small block Chevy. I don't think it was worth the money, Those suckers are expensive!I run file to fit rings now. Way cheaper and work fine. A few of my buds that have race cars don't think the zero gap rings are worth the expense either. Just my opinion. Others may disagree.I think porting is always a good thing if you don't over do it. Blend the bowls and gasket match the port openings. Tons of info out there on how to do it.
only reason i said no to it was i called up lc eng and they said that there 22r head would out perform a 20r hybrid so yeah but its best to hear what ppl are using and i say if it kicks use it
