Any suggestion in building a 22r? I want to get the most hp i possibly can. I see LC engineering has motors pushing 200hp, that's what i want. I was told to bore it .040 over and put a 20r head on it to get started. Is that true? Or is the a 4 cylinder motor with 200 hp that would fit ?

Over-boring any engine increases displacement, which is good.
.040 is the max Toyota reccomends for the 22R, although there are piston kits available for more than that.
Putting a 20R head on a 22R block will increase compression, but that only works on a late 84 or earlier block.

Actually it is possible to run a 20R head on an 85-95 22R/22RE block. In order to keep the cam and crank centerline consistent with an 85-95 head, you must mill the 20R head to a measurement of 3.130 (measured from the bottom of the front cam journal to the deck of the head). Also need to re-machine the oil passage back into the deck surface of the 20R head after milling to retain oil passage to the top of the motor.
Give LC Engineering a call and they can perform this service for you or they can send one built to your specifications. They're full of information too if you just need a little advice.

ok thanks for the help. I think I just might save up some money and just get a motor from lcengineering. But untill then what is a good cam I could get? I only use this for offroad racing at a local track. I need more power. I have a header on and a holly carb. Thanks again for the help.

Check engnbldr.com
They have cams and a bit better pricing than LCE or DOA.
