Custom intake manifold
In the past week, I've fabbed a custom intake manifold for my Toyota Camry V6. It's a simple piece basically reusing the stock lower runners and welded a custom tank. This is an upper manifold piece, and there are no injector bungs that gets into the way. I don't have pics of the inside, but it is ported and radiused. Here are some pics of the IM

Grocery list:
1MZ-FE stock intake manifold: $150 CAD
Aluminum material: $65 CAD
McMaster-carr Aluminum Elbow: $55 CAD
Welding rods and gas: $60 or so CAD
Sanding discs and polishing pads: $20 CAD
I will be postings pics of the finished product later tonight. It's going to be a polished aluminum finish
Some other goodies include a custom engine mount:

yeah, i would really like to know if it provides any extra power... i would think that it has the potential to provide you with some power gain, but all i've seen of that motor are what i see in this thread, which isn't much...
i would like to do something like this to a corolla motor i have (from a 98, don't know the engine code)... hopefully i can use the motorset in a dune buggy instead of another corolla...
and in looking at the top pic better... man, how fast is that thing?

that looks great, and what idea. only critisim i have is that most people that do this seem to be in a hurry and don't chanfer the welded area. I would think that the aluminum welds would look a tad more level if some bevel work was done. Just something to think about, that's all . great job!!!
Thanks for the great comments... It's great to hear these compliments and it encourages me to do more custom fab work
The stock intake manifold is a pretty shitty piece. It has a dual stage butterfly and a divider assembly built inside the stock manifold and poses as a huge restriction... Plus the stock plenum is tiny and doesn't work well with boost at all. Just by increasing the plenum volume should show some improvements, but it is really hard to come up with a good design when I am basically the only guy going to such extent with a Camry V6 motor
That is why I am afraid to do custom runners and used the stock ones because I want to avoid building a manifold that could potentially harm performance.
Hey FulldragCRX, the inside of the box is also welded and I will be grinding down most of the welds that are visible. That is why I didn't chamfer the edges just to save some time.
The material is 1/8" thick aluminum. The flange for the throttlebody is a 5/8" thick and I used a hole saw to cut out the opening
I have limited tools and my work area is my basement
The manifold is still being polished... It's taking longer than a expected! I should be able to finish it and install it later this week

Wow, that is great work, it inspires me to actually start working on mine. I drive a turbo Maxima, engine layout is almost identical to yours. I've got a spare IM sitting here that I may get done similar to yours.
Thanks for the great comments guys
Anyway, I just finished polishing the manifold and bolted it up

No idea... I just bolted it up a while ago, and it's night time right now
