1/24 wastegates???

I did a search but nothing helpful. racinresins' site is no longer running so where can I get a 1/24 external wastegate? There's a few models I could source them from but wanted to check if anyone knows a place that makes them?

I did a sort of how to on these, all you need is a punch and die set. I believe we're talking about the same thing - wastegates = dump valves etc? Will try and find it.

Couldn't find the thread but found the pics. I'm no techie so i hope we're talling about the same thing.

For a dump valve/wastgate all you need is plastic sheet and punch and die set. These are quite expensive but well worth the money and have a thousand different uses.

Two discs of .20 and one of .10 sheet punched out, the later is slightly bigger than the first two.

Sandwiched together and that's it!

a wastegate isnt the same as a dump valve. wastegates control boost pressure, dump valves release excess back pressure when closeing the throttle.

That's a good write up Chris but I need a wastegate for serious power. Something to the sort of......

I made my own for a project I am working on, similar process to the one Chris shows, it's not that difficult.

Hey Chris, Nice tut. Where can I get one of those Punch and Die sets? How much to they cost?
I think those would be pretty handy.

that is a bit of a chalange. i saw in the tutorials how to make a airfilter and have ridges, you could use that for making the bottom piece, and some more styrene for the entry hole, and maybe fabricate a a top piece from styrene tube and putty. be creative

Yeah, I could scrathbuild it but I'd rather source a quality one from a kit I have in mind or try in track down a resin piece.

Besides Chris' punch-and-die sandwich example, which matches most other types of wastegate I've seen, it strikes me that the fancy Greddy one you posted looks about like a distributor with a rounded top. The kind of thing 30 seconds with a nail file would do...

Thanks. Do they ship overseas to the states?

:dunno: If in doubt, Google will sort it out! :iceslolan Do a search for punch and die sets and see what you can find;)

Thanks Chris, nice motto you have there.

Or you could "DO IT EBAAAAAYYYYYY!" (Like that eBay commercial that is so overplayed.)

If I was at home I could show you a picture of my turbo B18, it has a scratchbuilt wastegate. This is how I did it:

I took a lenght of sprue, it will likely be too big around but that's ok and put it in the end of an electric drill (Dremel is too fast, you'll end up melting the plastic.)

With the sprue spinning in the drill, use a file to make the basic shape of the wastegate. Then, CAREFULLY use a knife to carve the fins. This will take a few tries to get right. Fortunately, we save our sprue so we have a ton, right?

I then drilled a hole in the side of the wastegate and used a small velocity stack for the horn. The results can be seen on my Cusco Rx-7.

Edit: The velocity stack horn is actually for a Blow Off Valve. Oops. Attach it to the exhaust manifold and put a pipe leading to the downpipe and it's a wastegate... the shapes and colors are a little different, but the parts are about the same, in mechanism and appearance.

Thanks for all the tips guys. I got my hands on a Tamiya wastegate, actually 2. These suckers are monster.....and I love it. Be on the look out for a single turbo Supra sleeper.

A little tease.....huge turbo, scratchbuilt 6-1 exhaust manifold (cut existing ones off), carbon fiber induction and velocity stack. Also maybe a Veilside Surgetank/Intake Manifold.

Future, future plans is a Nissan Z32 V8TT.....yes V8
