Offroad truck intake manifold
« on: November 20, 2009, 12:25:00 pm »
As mentioned, I have been helpin' a guy who welds for me. A good airbrush artist, and fabricator. Hard to find in young kids these days. Here's the intake we whipped up in three evenings. Brandon did all the welding using my little 150 amp inverter. Nasty stuff welding thin wall tubes to a 3/4 thick manifold plate. A lot of pre-heat with a torch was used to help the weld flow.

Update on this intake combo:

It bolts on an ecotech motor out of a Cobalt. These late model motors are cheap to buy (300 bucks), but will only fit Cobalts & other GM type cars. If ya wanna fit one into a little race truck, ya gotta buy an expensive computer harness, OR do what Brandon has done.

-Build an intake, bolt on a Rochester 2 barrel carb. His carb was around 200 bucks, all ready to go.

-Take pinto style headers, for around 200 bucks, cut them and fab up new exhaust plate. Weld the header tubes onto the new plate using ratchet straps to pull the pipes around, caveman style.

-Install a '92 cavalier coilpack and turn the key....Aftermarket Accel coils are cheap too.

VROOM!

A cheap build, skirting around all the expensive sensors & shit, with not much nasty fabrication, after all is said & done, other than intake & exhaust plates, which were hand formed using a scriber to trace out the patterns.

Avoiding the computers, and laptop programming makes it easy for us old guys to understand, as well.

With its aluminum flywheel, his little truck should fly! The race schedule has started, but other things need finishing.

That's some really nice work. I was just reading about a company that developed a progressive twin turbo kit for the ecotec that makes that little engine put out 1200 hp. I don't know what else you have to do to the engine, but technology has come a long way from swapping cams and intakes to make something run better. I'm trying to find out more about it for a build I'm doing.
