R32 wont fit.

you just get some run of the mill shockers and springs (harder ones)

Or you can fork out $$ and get coil overs and stuff then you can play around with heights and stuff also.

Ive got 250lb rear springs and some hard bilstein shocks in my rear.

Previously i had some softer shocks and the squat was too intense. Harder ones have sorted my problem but not as much as i would like. I still have a bit of issue.

I do have 500lb's siotting next to em i will install one day. And maybe play around with shockers also now ive found a decent suspension place here that doesnt rip me for mega $$

Waiting for SK too see this one :P

Well you didn't have to wait too long........

Stiffer springs are a band aid, why don't you fix the problem properly?

I don't understand the logic. It's got too much camber change, it's not too soft. Stick 500 lb springs in it, fantastic no more camber change but now it's too hard. Fix one problem and create another, what a good idea :confused:

depends what you clas as hard for youself though, wouldnt that then come down to personal preference?

If im not loosing any traction, but gaining. Then i'd say thats a win for me considering i havent spent a sent as its all spare srpings/shocks that i have sitting here that came with the car.

Yeah its not having something made up to adjust it. That for me will happen if my cheap fiddling doesnt work.

But the stock suspension is far too soft in the HR31, it does need stuff a fair portion harder

i've just put coilovers in the front of my hr30 now they have 400lb springs, the car is not driven at the moment and i'm glad as i'd say it would be not nice ... all i have to do is push down on the front and it just bounces like a bobble head dog..

when were the shocks last changed?

well got any other ideas SK?

from what i can see, theres not alot you can do with the trailing arm IRS in the hr31's to stop the huge camber changes apart from limit the travel with harder suspension... :(

Sorry, but I simply don't have the time to write a long explanation on the workings of a trailing arm rear suspension. Simplistically, the idea is to change the wheel's movement arc by repositioning the mounting points. Offset bushes are a good place to start, effective and cheap. The next step is redrilling the mounting holes. By moving the inner mounting points upwards in the chassis you can lessen the dynamic camber change. By changing the realtionship between the front and rear mounting points you can affect the squat, hence lessensing the need for excessively high spring rates. By moving the top mounting point you can lessen the static camber, this is helpfull as it can be diffcult to achieve the balance by only using the lower inner mounting points.

The Nissan trailing arm rear suspension has been popular since 1969, so plenty of people know what is necessary to be done. There are a number of books on the subject, the one written by Peter Brock (no, not that Peter Brock) on 1600's is a good place to start.

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      By 25RBGT · Posted

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
