Is the F20B really a stronger motor then the H22 or is this just a myth? I've been searching for Info on the F20B for an upcoming H2B/F2B swap later this year. Most ppl will say that the H22a is better, more displ, more torque, its OBD1, etc, but 'most ppl' are sometimes wrong.
I've come across many statements from F20B defenders who say stuff like the following:
"the stock bottom end on the f20b is as strong as most after market parts..if not better due to hondas close tolerances ....in my case i will never have to upgrade the bottom end for my all motor build......even if i was going to there wouldnt be much use due to the fact that the rods are super strong ...
another plus is that the f20 uses larger mains 55mm vs 50mm(97 and up h22 use these mains too) a fully balanced bottom end and not to mention iron sleevs.....and no real need to resleve for forged pistons..
it bugs me when evey one calls it a torqueless wonde like b16s and such whn they really have no proof of it ..ive seen some dynos of f20bs put out 214whp with a ported head jun3 cams and an image header and almost 9000rpm with a broad power band ...never seen a stock block h22 make that power before ..in fact its hard to find many over 200 whp with more mods ..... that motor was build for one purpose..mugen needed a 2.0 motor for a race class and the of course were over with the h22...i thkn there was a stock block rule and thats why it was build so dam good....and these motors were making 300whp
it was also the test bed for the f20c (s2000)
and we all know its a great motor "
Is the F20B really a much stronger motor then the H22a? I've also read that the bottom end can be revved much higher then the stock 7200rpm redline with valve float being the only limiting factor? again is this just another myth since honda builds its engines for a specific redline and no higher.
Sorry for the long post, but if anybody could help clear up some of the F20B vs H22a confusion it would be greatly appreciated.
Thanks,
