Guys,

How can I tell if my bushes are stuffed?

What bushes are there that I can change myself, and needs to go to a shop? (ie. requires a press or something)

I can't feel any movement in any of the bushes, I can't see any sign of wear. But my rear end is loose while driving.

Below is a thread where I am discussing my problem, however I thought a new thread for the bush checking would be good as I couldn't find a thread elswhere, I am sure others will find it useful too.

Cheers

Chris

Look at the bushes for signs of wear, frayed edges, ripped sides, crooked crush tubes etc

Check for leaks, some bushes are filled with fluid.

Get large screw driver and lever the bushes, check for smooth, even movement front to rear and side to side. Not floppy or jammed.

Loose rear end could be HICAS, it is not your friend.

:D cheers :D

HICAS would be worth looking at - get rid of it and put a lock bar on.... At the limits is when HICAS is most dangerous. Your on the limit around a corner, tyres are struggling for traction and your HICAS suddenly decides 'hey im going to turn the wheels 1 degree' when on the edge thats enough to make you loose it....

Thanks SK. I'll see if I can work it out.

There aren't any leaks. I will check the other things you suggsted. I'm not sure what you meant by levering the bushes. I'll try to get to the car and see what you meant. Will probably make more sense when I am there. I assume you mean to lever the arms etc that the bushes are in?

I just got hit with the flu, so it's made it so I can't work on the car :(

Yep, stick a big screw driver in between the moveable part (radius rod, control arm etc) and an imoveable bit (chassis, sub frame etc) and work the bush around.

:( cheers :)

yup.. they're all shagged by that stage.. every single one, and japs don't replace them.

I have got a few replaced, but its an expensive job to get them all done at once.

Castor rod bushes in mine improved some large steering shake and general steering response.. rear hicas ends improved rear end stability.. front control arm bushes seemed to have improved steering feel through there and general feel.. Still got quite a few to go though.

eXc.. just as an indicator, if you got them ALL replaced at the same time, you'd probably looking at *around* the $2000 mark (including labour). You will save by getting them all done at once in the long run.

But that is a lot of money to spend at one time I agree, but if u want to keep your car for a while, and really wind the power up it will help you out and guy scratching his head thinking "why is this guy's car so fast?".. its the small things often that make a difference. But depends what you're into.. maybe if its just for drift bushes aren't as important as say track work or other events (but i don't know much about drift)

Yeah, I just don't have that. Plus I am considering selling it at the end of the year and getting a dedicated drifter.

I am still sick and havn't had the chance to check it out.

Thanks for all the help guys

ok, so I got it to a shop.

Front Control Arm inner and outer are gone. On One side,

Front Control Arm inner are gone on the other side.

Sway bar bushes front and back are gone.

Rear left Strut bush gone.

Bowers (local suspension people) Quoted me the following with SuperPro parts.

SPF1659K - Control Arm Kit Upper Inn/OUt Nissan - $413.60

SPF1483K - Bush Kit 200sx F C/Arm - $188.40

SPK2092BK - Bkit 8 Sway Bar Link Square - $25.50

SPF0903K - Kit 8 Univ S/Bar Link Bush (small) - $24.90

They didn't quote the rear shock rubber..I don't know why.

Can anyone tell me what the Whiteline equivilent is, and it it's worth it? SuperPro are also on the Whilteline site, are they one company?

KCA336 - Front Camber Adj Kit - Uppr C/arm - Is this inner or outer or both?

Cheers

Chris

hi, a really easy check to do on rear end is to simply jack it up, support on stands and check each wheel for movement. Grab rear wheel at 1/4 to 3 loc (horizontal at hub centre) and try to turn the wheels(as the hicas would).

If you get any movement at all the bushes are worn, most likely the rear rack components, and quite possibly most of the rear hub bushes. I have seen this in my own GTS4 and a friends GTR, the GTR had atleast 5mm of movement - just rocking wheel as above by hand, and now with new hub and rear arms you can feel NO movement at all.

Of course it is not cheap, about $1000, if you remove hubs and get someone else to press bushes.PLus another $250 for hicas lock bar. Most of the 'wiggle' in the back end will be taken care of just replacing the bushes without the hicas lock bar.

Those prices would be for the complete replacement control arms I would say, which include the bushes (one unit). I had to replace one on the gtst and it was $200 from nissan..

Rear shock rubber? you mean strut top?

Or do you mean the bottom eyelet? Depends on the shocks, but generally I would have thought you would just replace the shocks themselves..

Does anyone have photos of adjustable control arm bushes?

What happens if you put them in at the wrong place the first time. Can you move them? Or are you screwed?

I just pulled out the control arms, and the bushes look almost impossible to replace. I don't see how you could adjust them once you put the new ones in ??

Cheers

Chris

The adjustable bushes are eccentric, the bolt does not go through the middle. When you turn the bolt it locks into the bush and turns it at the same time. So, if you have the bolt say nearest to the arm you have maximum camber, and if you turn the bolt 180o you get minimum camber.

no problems adjusting it once it is in

Interesting, I called noltec and they said once they are in you can't adjust?

Perhaps whiteline are different.

As a comparison I was quoted $500 to replace and fit L/R front radius rod bushes & L/R front upper control arm bushes.

I am going to to them myself as I have a friend with a press.

Its not difficult to do, just be sure to tighten up the bushes with load on them, i.e not with it jacked up. Obviously tighten them up slightly when jacked up but not completely super tight. :huh:

    • Not a problem at all Lithium, I appreciate your help regardless. I've pulled a small part of a log where the target pressure was 28psi and it spiked to 36.4psi. I've only just begun using Data Log Viewer so if I'm sending this in the wrong format let me know.
    • Sorry had a bit of a week and haven't had heaps of time to follow this, so apologies if I've missed something - any chance of showing a log with the rpm, turbo speed, MAP, and wgdc all in one view? Definitely an "interesting" problem, and while it's definitely worth noting that there was a similar issue with the twins I'd not completely put all bets on the root cause being the same thing.  Keep an open mind, follow the data.
    • I built this engine approximately 12 years ago so my own head (brain) is a little grey on the exact hardware in the RB head, however what I recall is. Stock RB25 NEO TURBO Intake Camshaft HKS 260 degree Exhaust Camshaft (R34 GTR) RB25 NEO Turbo Springs  I ported/removed the exhaust stud humps found in the RB25 head so theres less turbulence but it wasn't ported/polished properly, just a hump removal. I've attached two pictures of the before and after to illustrate.     The ECU gets its boost reference from the nipple on the rear of the head on the intake side, behind the fuel rail. The wastegate gets its boost reference from a nipple on the cooler pipe immediately after the comp cover.  Could a decent pressure drop across the intercooler cause the wastegate to be seeing a higher PSI than what the ECU is seeing, and thus it can't control it accurately and quick enough?   We ran a line to the actuator and watched it open and close using an air compressor, while we didn't have a gauge on the line to see when it was cracking open, it was opening smoothly.  I just removed the gate now and even though the documentation says you need to open it in a vice due to preload (which I did), there wasn't any preload on the cap, which is something we noticed straight out of the box as well when new. This silver cap internally is threaded to the actuator rod that runs out the bottom of the straightgate. Not sure how I'm supposed to get this spring out to be frank.. Potentially but everyone else doesn't appear to have to stop at 500kw because of 6boosts design.  I would, but I think I'm getting to that point where if I'm going to do the head and make another 100kw, then I'm going to need a fancy gearbox and quite a few other things and 10k becomes 20k becomes 30k within a few months. I'm not necessarily sold on the idea just yet that the head is restrictive at 4000rpm (and what.. 300kw?) and yet doesn't seem to be restrictive at 7000rpm when it's making 500kw, however I'm obviously not closing the door on that theory.
    • Yeah - Half the problem is I know this sensor actually goes to 150C.. I'm pretty certain it is min of 11C. So still more data required I suppose. It's really quite hard to get the oil temp to 100+ then immediately pull over and take a reading before the temp drops. Annoyingly I suppose the range I really 'want' is likely 80 -> 120C. TBH the ecu can't really *do* anything with it, and the gauge itself is very visible... ...but you know how it is.
    • My EFR 8474 Black, made 800awhp on a roller dyno. at 25-26psi. E85. Shaft speed was around 106,000rpm 1.01 rear. The rear is maxed.  6 boost Turbosmart 60mm gate 3.5inch exhaust  Head is worked to the shithouse. Bain racing. VCam. 272 exhaust. RB28 - RB26 foundation.  You have an intake issue. Start getting proper data and I mean go back to the simple things.  - Pressure test your intake - Block off the Turbo BOV, you don't need it.  - Test pressure before and after your intercooler If your head is pretty stock, that is your issue. Especially if it is NA.  Take it off and spend $10k on it.
