Intake Manifold Modification
Meant to post these pics a couple of months ago. I was having a hard time getting to the intake and exhaust manifold bolts underneath after installing a rebuilt head and new header. Read on this forum about a few guys cutting out the webbing on the intake and it made a huge difference. I can see/reach everything now. just used my air tools/body saw and made short work of it.

Nice! Lot of work, but it helps. Just an FYI... you need to reinstall the heat shield to prevent heat soak into your intake mani.
I de-webbed a turbo intake a few years ago (N42 Left - L28ET Right)...

Not sure what exact tools tamug92 used, but:

When I de-webbed my turbo intake (search my posts for pics), I used a drill to put holes around the edge where the runners / webbing meet, then knocked out the webbing chunks with a hammer. Then rough finish the left over "nubbins" with a cylinder shaped carbide tooth drill bit, and smooth it off with a ball tooth bit. We've discussed dewebbing before... thus the reason for research before work.

yup i did it a few years back. i found the intake trapped tons of hot air beneath it so i cut the webbing out. mine doesnt look pretty but i never finished it as my car was my dd. now im gonna build a better intake with large runners. you definetly need the heat shield, it lowered the manifold temps quite a bit on top of what cutting the webbing out did.

Just wne to local production tool and they're ordering me a bit like nismo's except it's for aluminum. Showed them the pic told em what I'm doing and he opened up a book and said this ones better. Getting that, 3 1in flapper wheels and a stick to clean **** off sandpaper. Only costing me $30 for everything. I'm going to atempt this on my extra turbo intake before doing my dd intake. Any tips for someone never done this before? Especially on the porting...
