Hi Guys,

It's been a year or so since my C34 was nicked and I've been on the lookout for an M35 I could afford.

finally got a 2002 250RS with almost everything I needed.

First up - very nice car to drive, just what I expected, and as a family man, fantastic for going on holiday with the family and fitting everything in.

I have a few issues I need advice with:

Exhaust:

I bought this off a young fella who'd lowered it and replaced the exhaust with a straight pipe - not my style.

I've put a standard muffler back on, but all the wreckers cut the damn rubber hanging mounts. I've bodged mine up with wire, crimps, and some rubber mounts from a cefiro, but i need the three rubber mounts to finish the job. Can anyone help? 2 of them are 90degree twisted. As I said, all the wreckers cut them!

Suspension:

I live in post-earthquake Christchurch NZ, and driving a lowered car on streets that are buckled and torn is a nightmare. That and I'm not into driving a lowered car for all the bad attention it gets.

The springs it has currently are red and have Cobra 12263 tags (at least the rears do, I cant read anything on the front).

So what are my options?

Can I replace the rear springs since they are separate (I actually already bought some factory springs from a wrecker), or do the shocks need changing too? I don't know if the shocks are stock or changed when the springs were.

Can I just replace the front springs? Or do they always have to be replaced with the shock? I'm thinking of getting the spring shock assembly from the wrecker for the fronts also.

Alternatively, can I increase ride height - say to the ARX style? I believe ARX have bigger wheels and different suspension.

Wheels:

I have 17inch nissan mags and bridgestone potenza 215/55/r17s.

is it possible to get even larger rolling diameter (to reduce the effect of earthquake road holes) by putting bigger tyres on he same mags? ie 215/65/r17s - does that even make sense?

Handling:

Since I'm talking about raising the car, I expect that I'll get a bit more roll when I put higher springs in - right?

Can I offset this by putting in a better sway bar? should this be done front and back? My front bar currently has a number sprayed on it looks like 4181 - does anyone know if this is stock or custom?

I'll be checking out the service info on this forum to see what I should be doing to the car since it's done 160k.

Cheers

1. Got to an exhaust specialist shop. They will have hangers. Easy fix.

2. Just put the stock springs in. No need to replace shocks if they are just the factory ones as long as they are in good Knick. The fronts disassemble so you can change springs, it's not a one piece assembly.

3. I think arx have slightly higher springs on them. Other than that susp is the same.

4. Withhold any decision about tyres until you get the stock susp in place, I wouldn't put bigger tyres on it.

5. I wouldn't do swap bars if your doing all these mods to make it more boaty, because you'll find that while cornering is flatter, the car will be harsher over pot holes, and things you drive over with one wheel. The pic you posted looks stock, but give it a tap, if it's hollow then it's stock.

Thanks dude that's all good advice.

Hi Sam,

Welcome I'm from Chc and if you like I have ARX springs that came off my ARX. What suburbs you in? Your car looks mint!

I'm in North Linwood. Car looks mint but actually needs a bit of peeling paint work done... ...when I get round to it.

I could be interested in your ARX springs. I'd just like to know how much bigger than standard they are and would they look stupid with 17" wheels?

Otherwise I'm keen on more clearance.

    • Yeah, I don't believe the M35 uses a deadhead system.
    • Have you done your thinking backwards? 3 bar, 43.5 psi pressure drop being the presumed specification for an injector, means you need 3 bar upstream when they are firing into atmospheric pressure, and more upstream pressure than that when on boost (you add your boost to your rail pressure to maintain 3 bar across the injector) and you need..... less pressure upstream when you have vacuum in the manifold. So, presuming that you're idling at -10 psi, then you only need ~23 psi in the rail. I realise that I did not need to say all of that to you specifically Matt, once you'd realised your mistake. It's mostly there for complete clarity for others.
    • Have you reached out to the guys at Spool Imports? They are a Ross dealer, I can imagine they would have the rings just sitting on the shelf (I could be wrong).  
    • There's one for sale at Grand Auto Wreckers in Lonsdale (SA), for .... let's suggest the sum they're asking for will make you cry. You may have to embrace the idea of modifying the rear subframe to accept some other diff. You could probably find a way to wangle a shortnose into there, with a custom rear adapter and some sort of shenanigans to relocate the front mounts. This has probably already been done by others, so there might be some guidance available as to how easy/impossible it is, out there in the googles. But you possibly needn't restrict yourself to Nissan diffs if you're going to contemplate that. There are similarish Toyota diffs, possibly some Euro ones, possibly some Seppo ones.
    • The ball joint taper and arm taper have to match angle and diameter, but just doing the bushes is a much better option.....seems like the industry moved to "it is cheaper to replace the whole arm than take on the labour for changing this bushes", glad the aftermarket supports it
