Does anyone know if the F20B motor uses the same oil pan as does the H22?

i havent looked at it that close but at first glance they look the same.. if you can wait till next week i can tell you for sure...

im gona assume you have a f20b? is it a 5spd motor? if it is can you measure the throttle body for me? i got a auto motor and im trying to figure out the differences. my tb is about the same size as a f22a or d16y8

i was also wondering why the autos make 20 less hp than the manuals on the F20B setup....i know cams are usually different in these circumstances....add lower end power but lose top end power....i dunno

I can measure mine, but mine is / was an Automatic. I am converting it to a 5 spd. with a manual tranny from a prelude. Do you guys know if I will need a different ECU because of the Auto-Manual conversion?

yes, need new ecu

Magnaflow

Damn, Thats what I was afraid of... So I need an OBDII Prelude computer? That will work correct?

JDogg

the auto ecu should work.. you'll have a check engine light though.

Magnaflow

Hmmmmm sounds like I will need to search for an MIL eliminator then.

the oil pans are different. if you replace the oil pan with an h22 you have to get the same h22 oil pick-up.

Magnaflowe: Do you still have the ECU for the F20B engine for automatic trans?
