From what everyone said, I thought this would be a simple drop install. So far, here's all the problems I've had. (i'm doing this for a friend btw).

He has DC sports headers that I figured would swap right over but the holes are placed differently between the two engines so he can't keep his headers anymore.

The driver side engine mount is completely different...I didn't even think about this until I dropped the engine so I got to have the nightmare of trying to take the crank pulley bolt off and changing the engine mount that's bolted to the block.

Intake manifolds are quite different! the fuel rail's hose is on opposite ends! So I thought I'd just use his old manifold but the ports don't match (one has an oval, another has egg shaped hole for coolant. Almost every single vacuum hose is in a different location so you can't reuse the hoses (or you ahve to extend them). The throtle body is different.

I'm done for the night but so far, I'm just running into problem after problem. Hopefully i've finished with the rest of the headaches. I'm going to have to figure out if I'll get a longer fuel line or try to see if the fuel rail from the LX will somehow fit on the EX manifold.

Gnight...

 

are you using the whole motor or just parts? i am doing the f22b1 swap into my 91 accord lx and it looks like it should fit perfectly. i knew about the fuel line and the header won't fit because you are putting a vtec motor in. the header is made for non-vtec. what other problems are you having. i am doint the whole motor. taking mine out and putting this one in. why did the motor mount not fit? please keep me informed because i don't know of anyone who has done this swap. if there is they have not spoken up.

 

The motor mount that comes on the 94EX is just slightly but different to the 92LX (I put the model numbers because I'm not sure if non v-tec are any different). The 94EX engine mout on the block is about half an inch wider than the 92LX, the other part of the engine mount is about an inch wider (so it doesn't fit onto the car) AND it is longer by about half an inch. There's no way to use the '94EX mounts to fit it in the car unless you reweld the spot on the body. So you have to take off the engine mount off the '92LX and use those for the driver side.

All the vacuum hose locations are different also. The throttle control (where the throttle wire connects to) is also different. The 94EX uses two seperate where as the 92 is made to where both cables connect to one throttle control. Also on the '94 throttle body, there are two sensors, on the 92, there is only one. So i'm in the process of finding out what they are. I know one of them should be TPS, so I'm not sure what the other one is. On hondaautoparts.com, it just calls it "SENSOR SET, MAP"...

Are you going to be using the 94 or 92 wire harness?

 

i am using the 94 wiring. also what would i have to do to get both throttle cables? do i have to run new ones or can i use my one? why do i even need two of them? so are you saying that i have to take off the mount from my 91 motor and put it on the 94 motor? if i have to now would be good because i am replacing the timing belt so it would be easy access. i am not concerned about the hoses because it just takes new hoses which are cheap and easy to replace. also can i use the stock ecu out of my 91 or do i have to get the ecu out of the ex model? it is obd1 so i need a 94-95 ex model ecu. as far as the fuel line goes that will be easy to replace. it doesn't seem that hard to swap but i have not started yet so i don't know what i am in store for. is your ecu your selling will that fit the vtec model and if it does what are you asking for it? please keep me posted on your progress.

 

are you talking about the h series or the f series? I am talking about the f series so if you are talking about the h series I am confused!!!

 

well the vacuum hoses are easy yes. but the fuel line has steel ends that are crimped onto a rubber hose. You can't just 'buy' a new one at napa or schucks. I already called and asked (unless I'm wrong).

haha, no, I'm not talking about the h22. That's another engine swap on the way but right now I'm working with my friend to swap his old 92 motor with my old 94ex motor. Sorry for the confusion.

yes, the ECU is for sale because we decided to keep his old ecu and his wire harness since he has a vtec controller.

 

what are you asking for it shipped to AZ? need one soon because i am going to be swapping it within the month. can you get some kind of connector you can put on the inside to link the two hoses together? what about the throttle cable, what did you do for that? mine is also going to be turbo, already have the materials just need to put it in.

 

What color are the Seats that are for sale? Are they Leather and how much? What city are you in?

 

Fuel lines will have too much pressure to try to mess with by yourself unless you have the right tools. Or you'll end up blowing up your whole car. I found that some NAPA stores can custom make fuel lines if you bring the fuel line to them. They just take it apart and add a longer fuel line.

As far as ECU goes, just make an offer. For the seats, I don't think you'd want them. I forgot to mention that they are tan leather but torn.

 

damn that sucks

 

You don't even need to connect the MAP sensor on top of the throttle body. Just leave it unplugged. The 92 harness won't have a connector for it anyway. The 92 accord has the MAP sensor on the firewall under the black plastic control box.

 

Yea, I know that. Lucky for me, it turns out, the 94's TPS snesor was broken and Honda doesn't really make it easy to take the TPS sensor off. The screws that hold it on are i don't know what you say....shaved off so you can't unscrew it? (I'm assuming so they can charge you $400 for the whole throttle body if it breaks)

Anyway I had to spend an hour using vice grips trying to take the TPS sensor off the 92 to slap it on the '94. (I tried to just use the '92 throttle body on the '94 intake manifold but the bolt pattern is just SLIGHTLY off so you can't use it.)

 

how about $100 shipped? if so let me know or let me know a reasonable price. never bought a new ecu so i don't know what they go for. it is for the 94-95 ex model? what three wires do you have to put in the harness for vtec? also what pins do you use?

The screws you are referring to are shear screws. Here's how to remove them: cut slots in the top with a dremel and a small cutting disc, them unscrew them with a flathead. I've done this at the junkyard with my cordless dremel, and it takes 2 minutes, tops.

And you are right, Honda will only sell the entire throttle body at the parts counter.

 

Thanks. I was actually going to do that but because of lack of tools, I tried the vice grips....worked out so I'm good for now.

Now does anyone have any idea what to do with short fuel line? Turns out NAPA can't do anything about it. Like I said in a previous post, the fuel rail for 92 and 94 have connections on opposite ends....so now I'm stuck with a fuel line that won't reach the fuel rail anymore.

 

Swap out the fuel rails. Use the one from the 92. I think people have to do this when swapping H-series because of the same problem. I'll let you know when I get home and look at the H23 sitting on the stand in the garage.

Anyway, I put a 93 lude S F22 into a 90 accord last weekend and we swapped the old fuel rails and injectors onto the new lude engine. Worked fine. And thanks for the cheap engine, Doc Brown. It runs great.

 

Well, I don't know about your scenarios but in my case, the fuel rails were very different. Not one hold matched up to mount it onto the manifold. I found it easier to get a shop to extend my fuel rail. Here's a pic of what they did (cost was $25 for labor and parts):



They make 3000psi hydrolic hoses and crimps so I figured they can handle making my fuel line durable (only around 100psi) right?

Today I ran into more problems. Being that he has to use his own power steering/alternator/AC, I thought it woudln't be a problem. All the hose are the same pattern on the block. Turns out, they're in VERY SLIGHTLY different spots on the block. So the bracket to hold the alternator was hitting a screw that holds the power steering bracket. So I had to put it to the grinder and shave some of it away:




But otherwise, I'm just about done with swap now. Everything's just about put in:


Only one little problem i have left is that the o2 sensor is too long with his OBX headers that it is hitting his fan right now. Any suggestions on that? Are there shorter o2 sensors?

 

Well, finished the guys car and gave it back but now he's got more problems. I don't know if I caused it or not but his D4 light will flash and then turn the car off. I know it's a tranny issue when the D4 light flashes but who knows why? I haven't been able to go out there to diagnose it and count the blinks but either way, it's either gotta be a problem with the tranny ECU or the tranny itself. Anyone ever run into this kind of problem after a swap? It's not like i could have crossed wires since the connectors only go fit on certain connectors. :S

 

I don't know why the car would be shutting up but I'm almost positive the flashing D4 light is the vss sensor located on the tranny.
