What is the best head gasket for a stock 22r?
Everyone is going to say OEM. And i gotta say, i had one in the garage for a 20R from LCE and then i got an OEM 22R gasket for the hybrid build and the OEM looked and felt a hell of a lot better
Almost every reply is the same. Do the rest of the gaskets matter?
Dont think so. Theyre all basically paper
Some other gaskets matter in non-stock applications. Generally unless you need to account for decking, piston height, compression (both ratio and boost), etc, you don't need anything but an OEM
just stock, how about head bolts and oil pump?
I'd get a new oil pump unless you replaced it somewhat recently. Headbolts can be reused if they look good.
If you intend to have headwork done in the future, a cam swap or two, etc, consider head studs. If it's not going to be taken off anytime soon, re-use the bolts, but clean the threads thoroughly on the bolts, and consider using a tap to chase the threads in the block to remove debris. If you have some stretched bolts, you should replace them (obviously).
Generally my mechanic has recommended oil pump and water pump together, though I don't know if that's common or he just likes my money.
I ordered head bolts, oil pump, water pump, thermostat, and head gasket all from Toyota and a complete engine gasket set. now I'm looking for a set of steel timing chain guides, the timing set is brand new, but has the plastic guides.
^^ always ENGNBLDR for the 22r motors. Also, get one of their cams. I highly recommend the 261C, if only for the more realistic powerband and better torque curve. It's not overkill on a stock motor, and will still be appropriate if you have head work, a new carb, and new exhaust system. I'm not saying it gives your truck balls, but it adds a small nudge in the right spots.
I have another complete engine that I plan on building high performance, so this one is to get it back on the road
I would say OEM is best, however I did a head gasket replacement (plus a whole lot more) using a felpro gasket set and it's holding up great, drove about 40-50k miles on it so far. See http://toyotaminis.com/forum/threads/replacing-22r-head-gasket.20005/
Avoid metal head gaskets, I read that at least for the 20R and 22R engines those don't work so great. Interestingly the OEM head gasket on a mazda miata is metal with some non metal compound on each side, which is not sticking to it.
As far as I know the most important thing is that the head gasket is slippery, that is the material which contacts the metal allows some movement between the cast iron block and the aluminium head since the two metals have a different rate of expansion when heating up. To me it looked like the outer layer of the felpro gasket was made of some kind of carbon fiber material which felt quite slippery, could be teflon as well I guess. I am pretty sure the OEM gasket is very similar in that regard.
I got an OEM one, thanks
You really can't go wrong with any HG on these engines. I ran an OE for three years at 18 pounds of boost, then recently switched to an MLS gasket when I thought that I might have blown the OE. Turns out the HG was just fine when I tore the top end down.
I now run 26 pounds of boost on the MLS as my daily driver. No problems yet.
I used an OEM, have not installed it yet
