M20 intake manifold design thread
-
if you need help in the making of any parts let me know i can probably get it handled for you guys i run a fairly large machine shop so if you want something like a bunch of flanges waterjeted out i can get it done for you
also i'm with earl on the m4x manifolds but i guess i can just steal whatever you come up with and cut cyl 1 and 6 of to make an intake for myself

If you do some digging in that - they've never actually made one. There's acouple threads I've found on it - company advertises them and shows that as a reference but hasn't actually made one.
So what would happen if I ordered one of these manifolds? Would they just be like "oh, we were kidding" haha.. not that I would order it, especially if the picture represents the actual product, seeing as it wouldn't fit an m20 and if it did, the throttle body would hit the hood.

I would assume they'd do what most companies do - send an email saying the product is not available.
I wouldn't want to order one without seeing the final product anyways.

Serious note. I have plenty of materials now.
I have 2" 6061 with .125 wall.
I will be Welding 1" of tubing onto each runner, porting the piss out of it to make sure it's a smooth transition. And then from there I can weld to clean aluminum.
My plan is to make a die for a tapered inlet from the plenum, and I will use the 2" tubing.
7 degree taper? And then I will machine little radii for the first part of the velocity stack.
Or I might make a die to form a velocity stack? Not sure.
Also. I built a brake booster delete out of 1x4x4 aluminum and I think it's going to work awesome. It's installed but the car is not running yet. This leaves LOTS of room to play with. We will be doing an itb adapter soon as well.
I changed the pedal ratio to 6.2:1.

For the prototype, you guys should be thinking about the ability to swap pieces easily. Let's say your plenum is the right size but you need to swap out your stacks, you should be able to remove them and replace them with the new pieces. The finished product should be one piece to reduce turbulence. Prototyping is always easier when you can take it all apart.

I'll powder coat the prototypes for you guys if you'd like.

I like the idea.
Man I just want to have a huge piece of aluminum to play with for free. Id totally have a modular intake by now haha.
I would have to say plenum design is probably the hardest part no? I think I should weld a base plate right before the stacks, and I could have the plenum bolt on and off? Man that might be a bit difficult to manufacture...
I can't wait to get these rolling!!

one thing I would implement is a fit bolt/precision shoulder bolt screw/dowel pin for repeatable fitment when they are port matched.
I believe the S14 engines have something similar.
Hmm. That makes me think I should just Cnc port the welded part.... Much easier..

I think an m42 one should be next=P
I would love to build one! Have a spare m42 laying around? Lol.
I have an e36 shell ready for mockups too.
Oh and we have 5 e30's now...
Anyone interested in a lsx e30 with a zf 5 speed? I wonder how much I could sell one for..
Holy tangent.
Also that was my first ever intake runner weld. And that's welding cast alum(not cleaned even) to 6061. I'd say it turned out well! The rest of the runners look even better.
The next manifolds will be welded with some actual cast rod. Cronatron 510t I believe it's called. And more time will be out into prep.
I'm thinking sand blast an powder coat? Or wrinkle coat?

Zero updates from me. But hey I have a good start and I might be able to finish it but one question.
I can mock it up using an eta head right?
And hey Jeff wanna help me design to manufacture some velocity stacks? Haven't found a cheap way to build them yet ha.
