Well I have kept hearing this noise coming from the engine, I can hear it the worst when I'm not "on it" or cruising at around 60-65mph, at around 3,000rpm. It sounds like a really loud whining noise, like somethings whining and loose at the same time. All my belts looked to be in good working order as I had them replaced (timing, etc.) back in June when I bought my 94 SI.

Took it to the dealership today and had my service advisor hear it and we couldn't figure out what it was... Sounded like from around the intake manifold, so I was hoping it was just like the IM gasket or something small like that... Well a tech at the dealership that owns a 93 SI comes out and hears it, and announces to me that my main bearings are shot. I thought about that about two weeks ago and was hoping it wasn't true. This sucks because in June when I had my belts done, they found three oil leaks and I had them all fixed at the same time, spent $1200 on it total. My uncle has owned the car before me since around 1999ish, and was in the Navy for 6 years, then went to NC State for two, I bought the car back in June. He wasn't very responsible and basically took shitty care of the car in general, including not changing the oil when it needed to be done. Like I said, I spent $1200 bucks on the motor thus far, AND I did a compression test last week and got ~220psi across all four cylinders. I hate that my otherwise healthy motor has to come to end like this...

I had just started piecing together my turbo setup too...

So now the question is, how difficult would it be to put an F22B1 motor (yes, a SOHC Accord motor) into my car? Any differences in wiring (I am a n00b to electrical) from a DOHC, non VTEC motor to a single cam VTEC? I know that F/H series are basically interchangeable no matter what it is, I can use my axles I have now, etc. What all do I need to make sure to by to get this thing on the road? I know I need a motor, and an ecu seeing as how the motors are different both in the number of cams and one having VTEC. I'm going to go ahead and grab the transmission for the F-series too, my synchro's don't feel so good in mine, and on top of that the car has the original clutch @ 166,000 miles.

Basically Im not happy with how the motor currently in the car is turning out, so I'm trying to see what I need to make the F22B1 work. Yes, I only want the B1, not anything different, NOT an H22A or anything. I just need to know about getting the F swapped into my car. Thanks guys,

Michael

I posted this same thread on PreludePower.com, and after I specifically stated that I didn't want to hear about an h22a swap, or fixing the h23. I only need information regarding to putting the f22b1 into my car, not anything else. Thank you.

 

What is in there now?

 

DOHC non-VTEC motor found in an Si, h23a1.

 

Thanks jackass. That's the end of my contribution to this thread.

 

What the hell? You asked what motor was in it, and I told you... I didn't mean to offend you, I know you're smart as hell man. Sorry.
Just trying to find more information?

 

I thought you were being sarcastic. My b.

Don't trust that honda mechanic so much.

Does it make this sound at a stop? If you mess with the gas pedal can you replicate it?

Try doing it with the clutch pushed in, that way, the transmission will be completely uninvolved, see if you can make the sound like that. If not, your engine is fine.

What you have sounds like bad transmission bearings, probably differential bearings, but we'll get into that after you get back to me on the first part.

 

I tried it just to make sure with the clutch in/the car in neutral so there is nothing transmission involved and it still does it man, I think he was right. It's very loud under the hood/in the car, sounding like it's coming from under the valve cover. I had a valve adjustment done back in June when the other stuff was done, I don't think it's anything head-related. It all sort of makes sense though for it to be the bearings since my uncle didn't change the oil when he was supposed to.
If I knew how and had the equipment, I'd get a video for you to hear it. I might look into borrowing a friends camera or something to give you a better idea of the sound.
Thanks for your help,
Michael

 

Anyone know about the wiring, or how hard it is? I'm going to school currently for Automotive Systems Technology and I'm in a basic electrical class. If you guys think I could get by with knowing the basics, let me know. I think it'd be cool to do my own swap instead of having someone else do it...

 

I honestly don't know much about that particular swap, so I can't contribute much to the original post, but since you will be pulling the H23 out anyways, you could always pull the crank to inspect how severe the damage is...If it's salvageable, you could have it balanced and polished for reasonably cheap, get some new main and rod bearings, and go from there. Just a suggestion to save the hassle of a complete swap and wiring headaches and probably save some money.

However, if you're paying a mechanic to do all this work, that may be a different story on cost efficiency...good luck with what you decide to do man
