1969 'Rally-Rod'

Update July 2015: I'm not sure if I've simply grown used to it or if clutch engagement indeed continues to become smoother and easier, but my Wevo streetLite clutch/flywheel and I are now the very best of friends.

Update July 2014: with more use the clutch action has smoothed out a bit. I'm still not certain I'd chose this clutch/flywheel package if I were starting over, but it has become a little easier to live with.

Original post February 2014: I have mixed feelings about the Wevo StreetLite clutch and flywheel. It is very light and I find the friction material a bit too aggressive. Shifting gears smoothly while rev matching requires total concentration at all times. Pulling away from a stop cleanly also requires a lot of finesse and is just plain hard work, and since I live in downtown Chicago, I have to do this about 300 times before I am out on the open roads. Once out on the open road it is very nice. It also transmits a lot of noise in to the cockpit at all times. If I had it to do over again, I'm not sure this piece would be part of the build. Maybe I'll change my mind after a few thousand miles?

I can't imagine NOT using a Wevo shifter on a 901 or 915 equipped 911.

You can also see an ignition kill switch in this shot.

The 'engine' section comes close to the end of my build description because it wasn't the most important aspect of the build to me. We weren't trying to push the envelop with the engine - most important was that it was characterful and reliable. It does provide a good hard shove in the back at full throttle, and like any good mechanically fuel injected 911 engine has that you-have-to-experience-it-to-believe-it instantaneous throttle response which makes it a joy to drive.

LN Engineering also provided the connecting rods:

Aaron sand blasted the obnoxious-red MSD boxes so they look decent:

I don't recall the exact specs of the head modifications, only that the ports were enlarged and reshaped for improved flow, but it was kept fairly conservative.

Magnesium throttle bodies and stacks were bored out to match the larger ports in the heads and rebuilt with Matt's usual attention to detail. They are really, really light!

I'm really happy with the DC60 cams. The engine idles smoothly and pulls strongly from fairly low RPM, but still has that exciting extra punch when the tach sweeps past 5000rpm like an old-school "hot" cam would.

As mentioned before, one of the things I love about the 911 is how 'modular' everything is and how an oil pump from the 2000's fits an engine case from the 70's.
