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.

    • I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.
    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
