How come no one makes a full replacement silicone SMIC pipes?

[Maximal]

If you're having issues with the CX Racing stuff let me know Greg and I'll make sure it gets to you in one piece. The coupler issue is annoying though. If you wanted to source your own I can see about a kit without any if you want.

As for the original question it's mainly that no one is going to spend the money to develop these for a small platform and it's nothing that the actual 3S shops can make. I would take a set of silicone hoses over hardpipes any day, just for ease of installation.

Weird. I made all my own piping with cxracing pre-bend pipe sections. All 90s, 45s, and one U bend. The stuff is 2mm thick and easy to weld, and it really wasn't hard to do. I never modified one of their "kits" for our cars though. Do you have pics of what you tried?

Just sold that pipe set...

I might still have the modified 90* piece somewhere. I used a 45" coupler to a 90 which went down to the drivers IC. The order was IC -> 2" coupler -> modified 90* hard pipe -> 45* coupler -> CX racing hard pipe (which goes across the front of the engine to the y-pipe)

It was too tall and shortening that 90 anymore would have gotten into the radius of the bend.

Terry, if CX Racing could replace that funky "whale penis" coupler with one that was 2" I'd be happy. ...and if their y-pipe BOV hose was a true 1.75" adaptor instead if a 2" so that the stock rubber BOV hose fit without a fight, the whole set would be perfect.

Does someone have a donor hard piping kit they would want copied into silicone? There are outfits out there that would gladly do the development work both domestic and international.

I have no clue what costs would run but the option is out there for those with sufficient interest.

I think it like this: pressure drop + and +

iirc our tb is 68mm or so

TB is 60mm.

Compare that to 300zx who uses dual 50mm. Supra 70mm. Don't think any of the 90's japs has a smaller tb inlet than the 3s. So it is kind of undersized imo.

This is kinda the direction I'm looking at going. If I can find a supplier, ill produce and sell a few sets.

Why do you want to replace 3 steel pipes so badly?

- you will always need a metal tube at the rear turbo for the oring.

- the 3 steel (non y pipe) tubes are above the exhaust manifolds or in position to rub against the chassis. Replacing these with silicone will only mildly improve serviceability and potentially hurt reliability.

I think the stock setup is awesome and I miss it. Replacing the old rubber hoses with silicone seems perfect, but aside from weight (negligible) why worry about these 3 steel tubes?

Because there is no such thing as a true 2" SMIC pipe kit for our cars.

Like I said above, if there is a way to adapt the current pipe kits, I'm all for that as well.

[AdamVR4]

So now it's about pressure drop through those 3 steel tubes? Have you done the simple analysis to determine the potential benefit?

The $160 kit mb3000 posted will be tough to beat, imo.

so with CX kit you just have to replace 5 couplers to straight 2" and the snorkel to a 90" pipe.

chop this to 5 couplers for price save 2" 50mm 1M Straight Silicone Coolant Hose Length Intercooler Pipe Blue | eBay

and get this Universal Aluminum Intercooler Pipe 90degree 2" 51mm | eBay

And done. 2" all the way.

But true cx doesnt always deliver quality. Their welds car be shitty. So check the insides of the pipes for loose alu pieces.
