Duncan,,,If I ever catch you with a jack under a brake disc your gonna look pretty funny walking around with your torque wrench up ya bum.

Neil.

i was just going to say the same thing... then i remembered that time when duncan badly needed rear discs due to cracking... hmm. perhaps part of the lower arm is a more appropriate place to jack it up. :P

This is a picture of a Whiteline rear spring installed in an R34GTT.  Bit hard to tell from the angle but the top 2 coils are closer together than the other 5 coils.  This ensure that the spring is trapped at full droop (as in the picture).  Once the weight of the car is applied those 2 top coils collapse, sit on top of each other and the suspension movement (eg; compression over bumps) is then taken up by the remaining coils.

I will be very interested in how you find the handling and ride with your design of rear coil spring.

:P Cheers :D

Well I'll certainly keep you informed.

I can see what you are saying. Perhaps mine are not progressive rate springs?

The sucky thing is that because I've been driving around in a stock suspension R31 since I blew the engine on 11/9 anything will seem harder. It will probably take a week or 3 to be able to feel the difference between the old setup and this one.

Luckily I've got another complete set of king springs sitting there which can go in if these ones turn out bad. It's not too hard now I know what I'm doing and the bolts have been recently cracked making it a bit easier.

Here you can see the difference between the unladen stock front springs and the whitelines.. This is in an R32, but similar. I really liked the fact you didn't have to use spring compressors to get the whitelines back in, they are pretty much a "perfect" fit between the strut top and shock.

It's all fairly even. Looks like I've lowered it 2.5cm which is what I wanted. I've driven around a bit and it's firmer than before but not ridiculously so. It was still ok on the highway down the coast and some fairly bumpy roads down there.

I'm yet to get to the track but we will see when I do.

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
