I might need some of these reducers as well when i look at replacing the front mount 7mgte supra cooler i have fitted on the car atm (they are heaps restrictive) for a hybrid one (the angle grinder will be my friend when fitting that)

i had a mate who managed to get some thick rubber 3" 90 degree bend hoses that they use on truck intake piping when he did his hybrid cooler piping, i might see if i can find out where he got those from, they might have step down ones...

I got some thick as 2" rubber hose for my cooler piping from here:

Industrial Hose and Fittings Supply

Unit 1A, 64 Kewdale Rd Welshpool

ph: 08 9353 4900

Only cost me $23 for a metre long length, its rated at 60psi and has not slipped off yet, sure its not bling bling silicon but it does the job well. They did have silicon hose as well but when i priced it up i found it too $$$. They supply to the mining industry and had the aircraft grade hoseclamps so they might have what you are looking for...

Alternatively you could head to an exhaust shop and have 2 of them made up, but you still need the silicon hose joiners..

let me know how you go with it all

modyourcar has silicone reducers for around $39 each from 2 1/2->3inch so all you will need are a couple of those.

Is the standard pipes on the r33 3inch? or 2 1/2inch? im talking about the turbo and manifold pipe. i want to go back under the coller and not over the fan, using the existing plastic pipes from the standard cooler.

God Bless,

Nate

For those who may be interested, I have some stainless Apexi GT-Spec intercooler piping for sale for an R33 Gts-t. This includes all silicone joiners, hose clamps, and all brackets necessary. I bought the kit and just used the cooler on my car. looking for $350. It is painted in the apexi metallic blue colour with some scratches. Looks mint polished!! pm me if interested.

Since im over here in WA forum looking for brake pads, ill stick my nose in.

Mild steel is fine provided the person welding it knows what they are doing. If they use the wrong consumable, or stick weld / mig weld then you will never get a very good result. You can make mild steel pipes that make ppl go oooh ahhh all at a price that allows you to get them ceramic coated with the change.

If you dont ceramic coat them it would still be wise to give them a coat of paint,

My recommendation is using a tig welder is more critical then the material you use, so is making sure the tube is adequately purged

I used stainless only becuase i had off cuts from work. Otherwise i would have used mild steel as its cheaper to buy and readily available in thinner gauges making it lighter. But stainless is cool too:)

Update - the cooler is in!

After a few hours working my poor "IT-hands" I did it. Didn't actually need the 45degree bend I bought, and only used 500mm or so of straight pipe, but meh.

I have the 180degree bend thing happening under the car now, so I'm gonna test it at the next drags and see how I go, if I'm not happy with the result I'm going to change the piping to the over-the-engine styles.

For $690 all up, I'm pretty happy!

Unfortunately took no pics, I just wanted to get it all installed!

Using the stock piping return I used:

3x 90degree stainless elbows

1x 180degree stainless bend

about 500mm 2.5" piping.

Got them from Allbend engineering is Ossie Park

750mm 2.5" Radiator hose

12 Hose clamps

Got them from Enzed in Ossie Park

2x 3" -> 2.5" reducers

Got them from Coventry's in Morley

Assorted bolts/nuts ally strip and stuff for mounting

from Bunnings in Subi

Oh, and the 600x300x76mm cooler from WorksAuto

I'm a bit concerned how low the return pipe sits to the ground, being lowered on coilovers doesn't help! But it'll do.

My first drive found me blowing a cooler pipe off on charles street (how embarrasing) but after I re-tightened them all, it works a treat, had it up to 14psi :rolleyes:

One way to get around this is to get a centre punch and put about 4 "punches" around the ends of the pipes, just go from the inside out, this helps to give the clamps something to bind too.

Or just put some more elbow grease on those hose clamps...

    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go. 
    • The roof is wrapped
    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
