Hey guys

got my hands on some second hand bilstein coilovers to suit a 33 gtr. they have helper springs on the front which are eibach....and the other an unknown spring (see pic).

first question....are these good for a track only gtr?

obviously i need to have the spring rates checked and the whole things looked over. where's the best place and around how much am i looking at?

thanks

the best place in sydney to get the springs measured and the shocks tested is bilstein/heasmans in tempe. they are excellent.

as for how much it costs, give them a call. and just from looking at them they are pretty heavy springs, up around 10kg/mm or more I'd say.

They look familar... Can I guess you bought them from a guy in qld? If so then I think you will find they are about 14kg/mm.

You can just get some lighter spring rates and have them revalved to suit providing the internals are still in good nick.

Gary at superior suspension AKA sydney kid could help you out.

First job, read the numbers embossed into the Bilsteins, around the shock body, down near the lower mount. Should be something like B46------

Second job, read the following thread, measure the main springs and I will work out the spring rates for you.

thanks in advance gary

(didn't take spring off)

coil od: 85/85mm

wire od: 12mm

# of coils: 10.25

Bilstein shock number: 0701 B46 2108 HO

let me know the result.

cheers

365lb/inch (6.5 kg/mm)

That Bilstein part number is for a rear shock for an R33GTR

If that's the rear spring rate then it's too high for a track car on "R" type tyres, let alone a road car. It's an OK rate for a front spring on a track car, but a little high for a road car.

Cheers

Gary

thanks gary

i'll try to measure the front springs shortly.

how will the helper springs effect the situation?

what would your target spring rate be front and rear for a track only gtr?

is the shock a good platform to start from? or should i be looking at a whole new setup?

  • 2 weeks later...

i finally got around to measuring the fronts...

coil od: 90/90mm

wire od: 12.75mm

# of coils: 7.875 (very close to 8)

bilstein part number: 734 1471 H001

Gary, could you please work out the spring rate at let me know if the shock is good or bad?

Also, if you could answer my questions in my post above it would be great.

thanks again

    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
    • OK, if it idles at 1000+ with the AAC, its not an idle airflow problem. The cold start valve just gives extra air when the engine is cold, but you have enough air without it to idle at 1000. I think you are back to a fuel problem, sorry. Can you see the fuel pressure staying constant or does it drop as the revs drop to a stall?
