Im new to hondas but I now own 3 4th gen accords and a 5th gen motor I was just wondering if u can put a b2 head on an a4 block

 

Short answer is Yes... However, doing that swap is actually a down grade compared to the stock PT3 heads that you have on the F22A* engine.

If you are looking for a bit of an upgrade. You could take the B2 cam, springs and retainers and put them into the A4 head and call it a day. Or if you have/find an A6, that cam and springs would be a touch better.

 

What would be the point?

 

it could handle more reves. And i would go with an a6 cam because it more lift and would make a little bit more power. the a6 intake manifold is also better because its bigger

 

I need to know if I can use my intake manifold and my exhaust manifold and wiring harness of my F22A4 on AN F22A1 long block please I need the info for this is my only car

 

Yes

 

Ok now im in a bit of a jam I have a good f22a1 and my f22a4 needs rebuilt and im low on funds can I use my intake exauhst and wiring harness of my a4 ont the a1

 

Ok thank you and this wont affect anything ill still have the same power?

 

Thank you to those who helped me with the Info I was seeking and I appologize for the overpost as I am trying to pass my trial membership

 

Yes they are pretty much the exact same engine. The A6 is the engine that is an upgrade to the A1/A4.

 

Please stop posting. Welcome to ht.

 

The intake will match up but the exhaust will not. You will use the a1 exhaust manifold.

 

Why won't his complete A4 exhaust bolt up to the A1 head? They both use the same head with a PT3 casting number.

 

I thought they use a different bolt pattern. I had ran into this situation when I did my swap. I thought the ex has a different bolt pattern than the lx model but I guess I'm now second guessing myself.

If you're certain then I will stand corrected.

 

No no that's why I'm asking. I always assumed that if they all used the same PT3 head casting that the bolt patterns for the header would be the same. In saying that, the down pipe and catalytic flanges could be different.... That wouldn't matter in this case where he swapping the head and maintaining the complete exhaust though.

 

I used the intake exahst and harness off my A4 on the A1 and it all bolted up and runs fine but I have a clutch issue I went to go for a test drive put it in reverse backed out pushe the clutch in put it in first started to let the clutch out heard a slight pop and went no where! Now while its running I can go thru every gear with out pushing the clutch In and it goes no where

 

Ok, I stand corrected. I guess I got mixed up when I was researching an exhaust manifold when I did my swap.

Ghost, it would make sense that the same casting number, in this case pt3, would have the same bolt patterns on the exhaust and intake. It's weird though cause when you look up exhaust systems the ex and lx are listed differently I believe when I researched before.

 

EX is O-OO-O
LX is OOOO

 

I believe that is becuase they have different length primaries and the O2 sensor is in two different locations.

Not quite!

All 90-93 Accords EX-R, EX,LX, DX & SE are equal exhaust port spacing = 0-0-0-0
All 94-97 Accords EX-R, EX, DX & LX are uneven port spacing = 0-00-0

One of the big reasons that ported F22B1/2 heads don't have the flow capabilities of a similarly ported PT3 (F22A*) head.

Ok I think I see the issue I was having. The head might be the same but the exhaust manifold isn't the same. Ghost, do the exhaust manifolds line up ? I think I assumed they didn't, even though they could.

 

The manifolds line up at the flange to the head, after that they are different. There is one that is a 4 - 2 - 1 and the other is a 4 - 1. The 4 - 2 - 1 has 2 down pipes where the 4 - 1 has a single down pipe.
