Im buying a real nice low mile F20a and for smog purposes i need to place the internals in my old F22a4. The crank bearings are the same right? Either that or i want to put the higher compression pistons in the F22 for a rebuild since they are the same bore.

Please DO NOT Post In The General Section
From this point on until otherwise briefed, posting in the general section of Performance Tech is prohibited. The only thing to remain here will be the stickies. We would just delete this section, but that would cause unintended results.
The majority of the threads created can appropriately be placed in one of the Performance Tech sub-forums or Technical; and the posting of them here is detrimental to the activity of said forums. If you have any questions about where you need to place your thread PM me or one of the other mods.
For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.
Everyone will get a couple of warnings from here on out, after that I just start deleting threads.
Again if you have any questions, PM me or one of the other mods.

Car Safety / General Servicing Checks --------Basic suspension checks

A "Finished" project car is never finished until its been sold.
If at first you don't succeed, Try again. Don't give up too easily, persistance pays off in the end.

i honestly dont think you check for block identification during a smog check. hell you could probabl have a f22b1 vtec and just shave the valve cover and the smog tech wouldnt notice. at least i wouldnt notice, lol.
Anyways...Everything will swap right in, make sure your a4 bores arent too big otherwise you WILL need a oversize piston.

Oh and does that account for the shorter F20 rods?Last edited by evil_demon_01; 09-30-2010, 04:50 AM.

like my project with running a h22 piston with f22 rods, im going to end up with the piston .040 out of the hole.
I have access to an f20c block....can i use anything?

All done
F20a inside a F22A1 block
Amazing, the engine block had 280,000 miles and the bore at its largest point was .002 out of spec.
Pistons were the same AABA
All rods bearins were within specs 1.2~1.5
Main bearings were mostly the same asside from 1 being smaller. But it was wore in to specs. These bothered me because they were getting close to outside specs 1.8~2.1
Talked to a rebuilder and he likes to run 2.5 on mains. Owell
