What is the difference between F series engine and H23?? - Honda Prelude Forum

purepowa · 11-14-2002, 03:45 PM

Wondering because my friend needs to swap and he had an H23 but got a F series...

Satan_SRV · 11-14-2002, 03:48 PM

Which one did he get?

The F22a is from the Prelude S....it's not so good...

with the F22 you're only looking at 135hp compared to 160hp from the H23

F = SOHC
H = DOHC

That's not true at all. There are several DOHC F-series motors

JDM F20B DOHC VTEC
JDM F22B DOHC non-vtec
JDM/USDM F20C DOHC VTEC (S2000)

yeah but honda has a certain method they use for their motors

F has 1 | = SOHC
H has 2 | | = DOHC
D has 1 hump = SOHC
B has 2 humps = DOHC
K = DOHC

F20B, F22B seem to follow that...F20c is just a completely different motor in general so i cant explain that one

The F20A in my 4g lude is DOHC!!!!!

92 SI Ludester · 11-15-2002, 01:03 AM

there are the few exceptions but this is the average of what we are talking about...yes there are motors that are different but 9/10 times this will be right

Dude that's just ridiculous.

Add the DOHC F20A...thats 4 motors that disagree with this theory. Humps and lines? You've decoded Honda's secret engine coding technology!!
