2.0 lude head on F22...???

[90exkId]

I was told a 2.0 lude head will fit on the F22 ... will this work? if so whats the PROS an CONS. B\c i was GIVEN a 2.0 lude head for free! not sure if its single cam over DOHC yet...... waitin to get it. let me knoe thanks!

[chrischhorn]

pretty sure it wont as its a B20 motor. That motor isnt even interchangeable with the other B series motors.

Yea the DOHC B20A is not interchanable with the F22
Like stated above it doesnt even share anything with the other B series, except it has the stampped B

However the the 86-89 Accord with the A20A3/A4 series might be able to use that head. It uses fuel injection. But then again, why not swap the whole motor

The A/B series are interesting motors, from what it appears is the B21A was the first Honda motor to use FRM sleeves.
Some made up to 160 HP stock, an H23 does that lol

Interesting, I have a friend with a worn out A20, Ill see if I can get him to swap a B21A in his car

@op no b series head or block will ever matte to an f or h series motor.

@cb7man
i have a 3g prelude with a b21a1 and it does not make 160 hp. it makes exactly what the cb7 A6 makes with 10 less tq. its a horrible performance motor but for its time it was the shit. b21a1 does have frm sleeves and thats the major problem with them because it burns alot of oil because of them if not properly maintained. ( and FYI the legendary b21a doesnt make 160 as u may find it makes 145hp which is even questionable because its only AUTOMATIC trans and makes more hp than the Si b21a1 5 speed. i call BS on that

b21a1 is obd1 so ur friend would have to go obdo to obd1 if he was swappin out his A20

guess i'll just sell it, that sux.

That head doesn't flow all that well anyway, and has next to NO aftermarket support. It's not a traditional "B" series... It's as much a B series as the S2000'S F20C and F22C are F series.

Sell it, and buy an H23A1 intake manifold. That will give you some gains.

I thought some preludes had the f22 motor in it and the only diff between those and the f22a's were the ecu?

Some ludes do have the F22, But the OP is talking about a 2.0L version which for a lude means its a B20.

Theres a non-US B20A "Gold Top" that makes roughly 160hp

Strangly I saw a 90 Lude with an B20A in the junkyard.

[deevergote]

You saw one of those rarities in a junk yard? Wow. 3g guys would KILL for that engine!
