So yeah. It took a day, but I got the Exhintake completed.
Whoa. It's a definately noticeable, nice change. There's a linear pull to the top of the powerband now that didn't seem to be there before. It feels less... peaky. Idles a shitton better too. Sounds slightly different.
There were a few things I somehow missed out on before I started, and things I'd do differently next time.
The cam lobes keep the cam from sitting level when you cut it. I'd make sure to brace the cam differently next time, as mine has a slight angle to the cut I made to the cam. Make sure that you have access to an abrasive saw and a grinder to clean up the back edge of the cam.
Don't use anything less than a bandsaw or abrasive saw. They act like a hot knife through butter.... but I imagine that this'd be a stone cold pain in the ass with a sawzall or a hacksaw.
Since you're going to be completely pulling the front of the motor off, it's a good time for a fresh timing belt/waterpump if you need 'em. My belt has under 10k on it, so I didn't need to bother.
When you drill a hole in the gear, make sure you drill it slightly towards center compared to the outer edges of the slots, the pin is about 1mm inwards from the outer edge of the slots. Whoops. Diegrinder is my friend.
Assembly lube, assembly lube, ASSEMBLY LUBE! I had a ton of oil on the cam, but still wish I'd used some.
Make sure when you say you have an exhaust cam and gear and are going to do this project... that you actually HAVE a gear, and your cam isn't wiped like mine was. Whoops. 2 for 2, had to scrounge/buy parts.
The car feels like it'd run high 15s in a straight line now, but I do have some supporting modifications.
Engine "mods": Fidanza flywheel, Unorthodox UDP, Racing Beat intake, Racing Beat header, Racing Beat exhaust, redrilled stock gear and no cat. Now featuring Exhintake cam. Basically a junkyard longblock, with boltons.
Costs:
Gear: 15.00 (thanks Bill!)
Cam: Free (and I guess whatever it costs to replace it since i had to bum one)
Machine work to gear: 60.00.
...so for 75.00, i got a noticeable change to the car for the better. I just wish I'd had a chance to dyno it before I did the install.
