i jsut had a b16a swapped into my 88 rex si and im having 2 issues
1. it shakes like crazy, especially when its revved or the clutch is pushed in, and in idle.
2. throttle response is slow
any suggestions?

 

1.what mounts? make sure the bracket on the rear mount is not touching the crossmember

2. check the timing make sure both cams are set right , some importers throw a new cheap belt on the motors as cheap insurance for them and might have screwed it up

 

sounds like your idle may be set a little too low try adjusting it. About the slow throttle response is it throwing any codes??? Did you do a tune up on it before swapping it in? Check timing, do a compression test, leak down? any of that?? that will tell you how healthy a motor really is. oh and good luck.

 

oh ok thanks,
cuz i had a new timing belt put it so maybe ill check the timing...
and as for the mounts they're new mounts id imagine this would cause the vibration

 

yeah with stiff b-mounts your car will rattle & shake in ways you never thought possible......at idle!

Werd. What mounts are you using?

I'm going to have to also vote wrong timing/loose mounts.

 

oo ok yae thats what i thought
ummm im not sure wat kind of mounts they but ill post tomorrow wat they are
but now im having "bogging" issues
and my car runs really cold is that normal?

 

Check your map sensor voltage.
A bad map will cause it to run poorly and vibrate more than normal.

 

how do i check that...
cuz you know how you check your ecu light wen you switch it to the on position and it beeps if its telling you a code... well my light doesnt even come on....
and for the other question
im using hasport street mounts

 

it obvious you didnt swap the motor who swapped the motor get them to fix it

 

Honestly sounds like your firing order is wrong, check to make sure your plug wire are corrects...

 

yea i didnt do the swap but thats because i gota killer deal on the engine and install price, lol i see why now haha should have just done it my self
but thats besides the point
i checked firing order plugs are right
ummmm ill have to do the timing
but do you think it could be as simple as a dirty fuel filter or even a sticky throttle?
ive tried everything and i dont know how to fix it...
but the thing is
when it happens i just need to let go of the throttle and then push it harder and it goes away(bogging)?
any one ever heard of this?

 

my old b16 used to to this but it had hf injectors on it. i think one of them were bad. theck shose out and give them a good cleaning.
