Modified LS6 intake

The issue of hood clearance is a result of the intake TB so why not cut the nose on the intake and angle it down a few degrees. I did a bit of research and it's well within the capability of the amateur. Since that describes me pretty well I'll be the guinea pig and let you know. The 968 has lots of room to the front but the hood slope is more extreme than the 944. If this works then I don't have to deal with the spacers in the crossmember and based on what I see now it would need more than 1" drop and thats not desirable.

Well, it's plastic, and the gasket surface is cut into it. I would actually be kinda surprised if it was do-able! Have others done it? Links?

I couldn't find that other had done it but found that it's nylon 1/1 and it takes some effort to bond nylon together. I found this [You must be registered and logged in to see this link.] and have the ph# of a local supply house. I figure a jig is needed to keep everything squared up but after that it shouldn't to tough.

They do something similar when making a stock ls6 intake into a 90mm ls2 TB.

The only thing I would be concerned about is pressure build up might cause an intake blow out if the engine is not setup to keep the back pressure out of the intake. No turbocharging or supercharging

I took the big jump today and did it. I spent some time finding a bonding agent and got Q-Bond. It's crazy glue with a fine powder. Pour a little powder on the joint and add a drop or so of glue. It gets really hot and in ten seconds it's rock solid. I experimented by fusing a couple of tie wraps together and confirmed it's a good bond.

I built a jig and cut the nose off at at an angle to remove a 1/2" wedge. I used a mitre hack saw blade and it was had work. In the last cut, perpendicular I couldn't get the blade to bite so went drastic going to a regular carpenters cross cut saw. Well, cats meow, it made a beautiful cut and took all of a minute to complete. I glued the nose back on and sacrificed an old black plastic mitre box to build up the reenforcing ribs and it's very solid. I did a test fit and the droop at the front is perfect. If I had to do it over I'd add a 2" long x 2.5 dia. spacer tube between the nose and intake to further lower the intake by a half inch.

All in all a very doable project. I took pics but left the camera at the shop so I'll post pics tomorrow.

Plastic epoxy (Wal-mart $3.50) is what I have bonded Nylon with on some motorcycle stuff.....looks just like the glue in this mod as well. Clean the plastic thoroughly with a final wipe down of isopropyl alc. and the two parts will bond rock solid.
