just got home pickup up a 22R hybrid 22 block 20 head with tranny all freshly built and completely ready to drop pics tomorrow and will have pictures of it being put in next weekend.
please for the love of gawd, double check TDC on that motor. wish i would of known before you bought. i know 3 people personally, that bought a "rebuilt hybrid" then got F'd for various reasons. but each and everyone of them could have been prevented by checking TDC. main pulley notch @ 0deg on timing plate #1 intake and exhaust rockers loose #1 piston @ top dowel pin on cam @ 12:00 rotor on dizzy points to #1 at the center of the timing adjustment for the dizzy note: this requires the removal of the valve cover, PO should have no issue with that. then just to be double sure, rotate the main pulley 4 complete times. it should end up in the same spot and everything mentioned above should be in the exact same place. if not, you may have a 20r head on a lazer block(84+), or have the wrong timing chain. if theres a single row timing chain on it, go back and beat the person you bought if from with it.
Everything ShoNuff said except this: '83-'84 22r's came with a single row chain but were the old block. Granted, when it was rebuilt this should have been swapped, but it is not automatically disqualifying.
No worries guys it legit as they come. The guy that built is a friend as knows his stuff he's been building these hybrids since day one.
updated Some currents pics, almost finished with the new motor. Still needs a final cleaning and finishing touches
yea......... i noticed the dipstick position too........ but if its gott the 22r stamped on the block on the drivers side of the block i guess thats all good? also, make sure to tighten up that bolt on the under side of the intake have you fired it off yet or still prepping? if all goes well........ it should be a real kick in the pants difference of what you had in there before!
Ray explained it to me, Its stamped 20R its a complicated story though. Long story short its a early 22R stamped 20R due to people being unsure of what the heck a 22R was yet.
I'd be interested in the complicated story, as that would be the very first passenger side dipstick, 20R stamped 22R block I ever heard of or seen in over 25 years of messing with these engines. By 81 when the 22R came out the drivers side stick had been standard for 3 years.
The hybrid is a early model pre 84 22R tall deck block with a 20R head, the benefit was it upped the compression by about 1/2 point and the small less restrictive ports increased port velocity which gave better throttle response off idle and in the lower RPM range, made the engine a bit more torquey at low RPM. Down side is the small ports and small valves hamper top end power and kinda run out of air in the upper RPM range. You can run a 20R head on a later 22R laser block but plan on spending some money to do so as it takes some serious machining, the other post stating there was only 2mm difference in blocks is incorrect, more like 5mm or nearly 1/4" needs cut off the head to fit it to a late 22r block and get the timing chain to work, the late model engine used a 96 link chain where the early engines used a 98 link chain.
that sounds like BS to me. theres no way in hell toyota would stamp a motor with another model # jus cause nobody knew what it was. if they did that, the first 1jz's would of had a 7m stamp on em. ive seen in person a min of at least 100 different 20r and 22r's and never ever ever have i heard of such a debacle or seen it. not trying to harsh your buzz or anything but thats some BS right there.
That won't really prove anything as both the 20R and early 22R used the same cam, dual timing chain setup ect. You do have a later model head as evidence of the drilled bosses for power steering and the fuel pump provision, the only way you'll be able to tell for sure is to measure the cylinder bore, and my money is on its an early 20R block and a story.
