hey guys,i have a b18c1 swap in my civic,when i get to really high rpms,like 7k and shift,the car jerks and doesnt really go into the next gear smoothly,i have a new exedy stage 1 clutch,no strut bar(dunno if that will help),maybe its a motor mount,hmm,or the new 1.8 engine is more powerful for the chasis?

 

does the shifter feel like its moving up when it does it??

 

Sounds like your motor mount(s) are bad. Buddy of mine has the same problem and his mounts are shot to hell. Every time he revs it to 8k and shifts, you can feel the motor shaking.

what he said.

 

how much are new mounts and how much would installation cost

 

check them first

 

how can you tell if there bad,is that the only thign that would make the car jerk like that,its alot and throws you back and forth

 

? hmmm... i don't know but you can check the mounts by looking for rip's and/or having someone load the car and see if the motor is is shifting to much

 

yea,anyone else have opions on what ot could be,also,how muchf ro installtion?

 

inserts on the torque mounts will help minimize it but if the main mounts are broken you should fix/replace those.

 

Motor Mounts x2 ... If you dont want to spend the ca$$$h on new ones - you could inject silicon and stiffen them up a bit. Do your tires spin when this jerking occurs? Does it jerk when shifting @ high rpm's from 3rd to 4th? Could be a traction prob.

 

to check ur mounts put ur ebrake all the way up as tight as u can
then have some one look at ur mounts
and put it in first gear and act as if ur letting it ouT OF GEAR AND WHOEVERS LOOKING AT THE MOUNTS SHOULD SEE IF THE MOTOR IS MOVING up and down. f not then it noe the mounts

 

could be your powersteering, i had the same problem but after i did a motor swap and the powersteering was disconnected the problem was eliminated.

 

well when u shift from 1 to 2 and 2 to 3rd the car totally jerks,no wheel hop,how did you say to check,can i just rev in neutral parked

 

First, check your lower torque mounts(the ones at the bottom). If those are shot, you get get ES Bushings for relatively cheap, or solid ones like I have. Then the other three. They're roughly $50-$100 at the dealership per, or you can get an aftermarket kit for about the same.
