Hi,

Can anyone tell me whats going on? I have just changed the motor in an R33 gtst which has khoni adjustables at the front, and the from suspension is extremely soft and bounces like a boat in waves as im driving along.

I did not touch the suspension at all, just a simple jack the car up, change the motor and put it back down?? wtf?

Any help would be greatly appreciated :blink:

sway bars still connected properly? dont think u need to take them off to change the engine, but it does go near to the sump so its possible. also did u have a strut brace on before? not usually a noticeable "handling" difference, mostly a mid-corner grip thing.

also was it a straight engine swap? u didnt put a heavier engine in did u?

Straight engine swap by replacing a S1 motor with a S2 motor.I dont recall at all undoing any sway bars. Was pretty much engine mounts, bellhousing bolts and the little things here and there and that was it.The shocks i think are khoni adjustables with a bolt at the top, and i think a something to adjust underneath.Its just like they are now ultra soft and i go over 1 bump and the front goes up and down constantly for about 10 seconds. Plus, it is bottoming out a lot more obviously due to the softness :(Can I simply adjust them at all? Is it the top bolt i adjust or underneath? (Sorry new to this)

Didnt drop the engine in to hard and bust the seals in the shocks did you?

Naa it all seemed smooth as! Dropped it in extremely carefully. But I suppose thats a possibility I may have done something.Another thing I forgot to mention is they are Coilover types i think. Ones with the adjuster at the bottom of the spring and the bolt at the top. Can it simply be a case of stiffening the spring? (Not that it explains what the go is though :P)

sounds like ur shocks are buggered for some reason, are they on full hard adjustment wise?

The bottom coil adjustment is about half/half, and the top bolt is just on the thread (ie the shaft of the shocks are just above the top of the bolt.

Would having the wheels in the air for an extended time do this? Because thats the only thing I can think of really.

i think you just answered your own question in that last sentence......

having the the wheels in the air for an extended period would put pressure on the shocks - weight of the wheels and brakes.

I know when I disconnect the shocks on the rear on my 1600, i can push down on the back and bounces a fair bit.

I would say shocks are stuffed!

Edited by petern

wheels in the air shouldnt bust ur shocks, as they are still in the static position, but will put a bit of pressure on the travel stops if it is infact the shocks which are suspending the wheel, often its the arms/rods or half shaft suspending the wheels up, and the shocks arent.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
