Hey guys i have a small question, i have a knocking on the f22b2 block a piston(s) is fucked up, so i have a friend that wrecked a prelude like 92 non-vtec with the f22a1. He is selling me the tranny, engine and ecu for 500 dollars is that a good deal the car has like 132,**** miles
So do i still need the ecu install, or can i still run it with the same accord ecu, and have the same performance?

 

is your b2 an obd1 setup?

 

if its a 97 as in his user name i think those are obd2.....correct me if im wrong

 

yeah you are right i din't think about that. yes his is a ob1 and mine is a 97 ob2.
So does that means that i really need the computer?
and having the prelude engine is't possible to get some hp by advancing the time?

 

that prelude f22a1 is the same as the f22a1 from the accords......might be like the f22a4, but that's just 5 hp if it is........solid engines....but you'll need all the obd1 stuff......ecu/conversion harness so the plug will fit, engine and tranny, tranny ecm, distributor and injectors i think.....not really sure...basically all that comes with that motor

 

get a obd2 to obd1 conversion harness. Then just swap with his ecu also.

 

just get another f22b2 and save the trouble

 

i would get another f22b2 if it would be at the same price but tranny with ecu and engine for 500 dollars that's a pretty decent price.

Do i have to get a conversion harness to be able to change the computers, isn't another way, if isn't where can i ge the harness?

 

you'll find another f22b2 engine for less than the $500+obd1 conversion and installation will cost...the mounts aren't the same as far as i know....not sure if you can mix the f22a and f22b mounts and find a correct combo, but i know a guy that's having issues putting an f22b2 into his cb7 .........it would be easier and cheaper to find an f22b2 because i assume your tranny is fine isn't it?

 

Is there another way where i could do the conversion without the conversin harness.

can i just cut the computer plugs and switch them?

i want to get the swap tomorrow

 

Who is doing the swap for you? If it's a garage then ask them for a quote before you decide if it's worth it. Otherwise this could end up costing you more then if you've just went with another F22B.

 

well the total for the engine transmission and labor is 800. but how we decided that we were not going to change the ecu, we ended up having some problems with the intake manifould, they are a little different , we try to put the f22b2 intake manifould on the f22a1 but there was a water line that was not exactly on the same spot. so what we are going to do is put the f22a1 block with the f22b2 head and intake manifould so it will fit, but i was wondering what makes the f22a1 have 5 hp extra than the f22b2?

If i put the f22a1 block and the f22b2 head and intake manifould will work perform as a f22b2 or f22a1

never thought about that(just using the short block). of course you realize you just paid $500 for an f22short block-- a little high in my opinion. Anyway, your engine should perform exactly like the old F22B2. The F22A1 block has the same bore, stroke, crank, rods, and pistons as your busted F22B2. I thought it had the same head too, but I guess not if the intake wouldn't fit.

I think it was the intake and exhaust manifolds that gave the F22A1 lude motor a few more horses over the accord counterpart. If you want an easy way to get that 5hp, buy a cheap header and CAI.

And doesn't your OBD2 motor have a crank sensor down by the pulley that the F22A1 didn't have? I might be way off since I've never examined an obd2 H/F series motor, but has the mechanic accounted for the extra sensor?

P.S., $500 for the eng/tranny/ecu seems a little high. I found a 94 F22A1 lude engine&5spd w/140k on tamparacing.com for $250 for my friend. His 91 Accord's F22A4 was burning a little oil then busted a timing belt and bent some valves. not sure if there was any piston damage. Anyway, I swapped the motor for him for free. In exchange, he gave me all the leftover parts-- Which I've made $300 off of so far. So he got a new engine for $250. I would've done the same for you. And i live in GA....

 

About the differences on the heads is just the water line but that's it, because i just finish putting the f22b2 head on the f22a1 short block and it did fit like a glove. and the intake fits but the water line is a little farther the the one on the f22b2 .

and about the inatake and exhaust manifolds the ones on the prelude they seem to be better than the ones on the accord.

Yes the mine had that crank sensor but what we did was that we pulled water pump cover and replaced it for the accord so that was not a big deal. and is because of that sensor that you cann't advance or retard the time.

I thought it was a good deal because i went to the junk yard to check how much they wanted for jus the engine for my accord and they said they wanted 600 hundred dollars. but well. i am almost done.

 

as long as everything is going to work, that's cool. I'll bet you learned a lot more about your accord engine doing it this way (mix/match black/head/intake). And yes, I believe the prelude header is more of 4-2-1 factory piece welded from pipe, while my accord's is a cast shorty header. And the intake on the prelude F22 looked a little bigger...

Let us know how it runs and if it feels any better, power-wise...

Plus you have a spare ecu and tranny to sell now.
