LS VTEC in, but shakes... HELP PLEASE
 

Well, My LS VTEC is finally in. Honestly it sucks ass compared to a turbo B16. VTEC will never be the same for anyone once they have experienced FI on it. I guess when I turbo it, it will be cool...

Anyway, my problem is, my car shakes under harder acceleration, and when I bring it up to highway speeds. It does this weird shimmey, side to side. What the ---- is that?

Did I do something werid with the mounts? EVERYTHING was hand torqued to spec, and I took REAL care of the axles. What do you guys think?

Re:LS VTEC in, but shakes...
 

new mounts? what cond are the sus bushings in?

alignment?

Re:LS VTEC in, but shakes...
 

I just had the dealer replace the tie-rod ends and do the alignment. The mounts are all the stock ones from the car, it's a 95 with only 110k kilometers, they all look great.

I just want to know why, I don't want to throw it in the dealers face and tell them they fucked up.

I would like to know if it is something I did from the swap. Or something I could do without some sort of calibrating machine.

Re:LS VTEC in, but shakes...
 

yes....alignment would be a good idea. but if your car ran fine before the swap...this motor shouldnt unbalance the car that bad. i had a problem before...with similar actions...and found out that the half shaft that sits between the axles was bad. If you pull off the axles on thr driver side, you can see how the shaft is spining. mine spun kinda in an oval...so...i replaced that and the car stopped shaking and swaying. the mounts shouldnt be a big problem UNLESS they are totally broken and gone. hope this helps. good luck

I had the same problem, the inside of my axles, one of the bearings broke, just the needle bearings came out, but it still works, just shimmied hard core.. check your axles...

Re:LS VTEC in, but shakes... HELP PLEASE
 

which intermediate shaft did you use? i had the same problem when i did a swap and it ended up being the bearings in the intermediate shaft, did you use one that you knew was good?

Yeah, I used my stock axles, it was a B16 del sol, I just put the b18b block on my tranny with my heads. Thats why I don't understand. Stock tranny, stock axles..... ???

Re:LS VTEC in, but shakes... HELP PLEASE
 

axles do just go bad...

Re:LS VTEC in, but shakes... HELP PLEASE
 

maybe they did screw up the alignment?

Re:LS VTEC in, but shakes... HELP PLEASE
 

I had the same problem after my b18b swap. It was crappy aftermarket axles. I also had a weird jerk to the right then the steering wheel was shaking on the highway, that turned out to be a lose bolt holding the lower control arm on the drivers side.
