I don't know how many of you people are DIY type guys...but I sure am. There are so many things that you can do by yourself, and save a lot of money, and have more fun doing it...you just have to have the mind set. I fabricated a dash for my racecar, a switch panel (with fuses and indicator lights), an intake (with heatshield), door skins, headlight brackets, Mounting bars for the FG front end, and I plan on fabricating my own exhaust, I even made my own valve spring compressor.. I love doing this stuff, it's so satisfying when you're finished.

So I'm now scheming up a plan to fabricate my own Individual Throttle Bodies.

I'm looking at hacking up a regular old B series intake manifold, porting it out, welding on 4 Geo Metro throttle bodies to the runners (or something of comparable size, 50mm or less. I know some Saturns have 50mm TBs), and then, of course, the air horns on the end. Plus some sort of filter, probably just an open element foam type filter. It all seems too easy.

Anyone out there with ITBs care to share some opinion on my idea?

Now, I've been studying a little on fluid dynamics and I know that a lot of the low end grunt would be lost with a setup like this (but with big gains in the high end). This is acceptable to me. But if I really want to get technical about it, I was thinking of making a variable intake runner (a longer, skinnier runner going to the airbox surrounding the air horns kept open for the low rpms, and then for the high rpms, an open element type system. This would get the best of both worlds. Of course, that's a lot of engineering to do, but I'm up for a challenge.

I'd probably end up cutting up my fiberglass front end to mount some sort of hood scoop to bring in a breath of fresh air for the things as well.

I guess no one has any comments..

I'll try in the competition forum.

 

Those Metro TBs are about 35mm. Perfect.

 

I think that's sweet. Go for it

 

if it works ill buy one!
what head are you using?
patent a kit...and make a killing, even if it makes twice as much as a cold air intake, you can still sell it, by the sounds of it smaller t.bs would be good for the street, and still be able to make good top end power

 

Well, I have a B16A head on my LS/VTEC, and my bro has a B16A in his del sol.

I hadn't thought about selling it. But that would be a good idea, and great to increase traffic to our website (when it gets up)..

 

exactly

 

Sounds completely possible. You will have to make sure that all the TB's are properly linked so that all the throttle plates open the same amount at exactly the same time. I would also keep the existing runners on the manifold slightly on the long side to help low end torque. If you ar good with a welder the fabrication should be pretty straight forward.

Couple that setup to a nice cold air intake and high comp pistons and you will have yourself quite an engine.

i would like to see some pics martini

 

35mm is way to small

 

I think so too. the ones they use on the TWMinduction ITBs are 50mm...That's inner diameter of course. The Metro ITBs probably have a little bit more padding on the outside.

 

Homemade intake manifolds aren't the brightest idea in the world. This one I made caused me to blow my motor.

 

I just s**t my pants laughing so hard...

Good one bro!

 

Damn, man i want to buy that brown intake mani, thats a sweet job. Keep up the good work, i'll be watching for a header in the near future...

 

hehe...

 

Now thats nice!

DUDE!!!!!! That is fawkin sick!!!!! LMAO!!!..............That is the craziest shheiit i have ever seen..........LOL......

 

hey....who's the pissed off lil kid in the window?

 

thats not a bad idea i would have to get it welded by someone else because id tear something all to hell if i was able to melt metal the itbs off the metro is that a geo metro or what and how would i fabricate a throttle cable braket so it pulls all four i think 35mm would be plenty for a dseries motor wouldnt it? let me know help me something its an idea i wanta use
thanks
chris

 

Oh you guys think thats funny? How about a lsd. 2 way sucka!



btw I do have a life and No these 2 things did not take a long time. Okay maybe the lsd...but the manifold took like 20min.

 

hahahahhahahhaha thats funny as hell

 

man you must have alot of time on your hands....

 

look at the disclaimer underneath the lsd pic foo.

 

Creative and funny.....
Totally brightened my day, thanks.

 

Do you make a custom cardboard turbo kit or a clutch? I like the brown poo poo......hehe!
