Hello.

Just performed a swap on my CRX and having unbearable vibration in the car. I've used HCP mounts. Any suggestions on how to get rid of the vibration? Thanks

Hi Yoshi:

Vibration at all speeds?
X-way speeds? what?
If its only at Highway speeds I'd be willing to bet a balance issue.
If its all the time check to see if one or both of your axles are bent.
Any more info would help greatly.

Did you 'clearance' (hammer down the lip on) the rear crossmember for the T-Bracket so that it doesn't hit?

But yes, more info is needed on how/when/what they feel like, speed related, or rpm related, etc...

Hello, again.
I'm new to the B16 swap. And I got the swap done at a performance shop last week. The vibration happens when I turn the car on. I can't hear anything when I'm outside the car, but when I sit in it and the car is running it vibrates a little bit. As for changing gears it vibrates even louder at a higher rpm range. Is there any work that has to be done to the frame or inside the engine compartment somewhere? Is there a manual for the B16 engine where I can read engine codes? Cause the check engine light is also on. Thanks for the help.

if the vibrations were only at idle it'd just be the mounts doin their thing, but it sounds like you got bigger problems.

How To: check your codes:
Under the hood theres a yellow rubber clip on the Driverside shocktower, take off the rubber cover, and insert a wire or paperclip into both sides after starting the car.
If they used a wire harness like a Rywire one, their may be wires for you to cross coming off your ecu harness.
Anyway, this'll make your ecu blink out the code, and if your obd1, the check engine light will blink it out.
1 long blink = 10
1 short = 1
long pause = break inbetween codes
count the blinks and add it up, ta da.

you can get more info on code checkin on rywire.com or ht or alot of other sites, id be more thorough but its dinner time

Also, I think it could have to do with the crossmember or some brace that wasn't considered. On my last swap, I left on the stock exhaust manifold bracket and this rested on the front cross member. I had vibration that was worse at 1500RPM. We couldn't figure it out and I ended up removing it and it relieved the vibration. Just get under there and look around and see if you can see anything shaking or your engine resting on anything.

Umm...the bold print really stands out to me.
If you paid someone to swap your engine and now a week later its vibrating badly I'd get that car over there and get it looked at pronto!
If they are a reputable shop they should 1:look at it immediatly.2:Fix anything they did not do correctly.They are a business that gets paid to do what you paid for.Don't be shy in having them correct any problems that may be from their install!
Let us know what they say.
BTW who did the swap?
