The spacer plates look significantly different between the l36 and l67s. Everything under $100 looks to be for the l67. I drive it about an hour each way to the track so race gas would add up pretty quick. I also put some street miles to work and such.
I agree the intake does look thin and brittle. I removed it today to get a close look at it. I found a unused vac port on the throttle body I am going to try to make work. The location is good but it is a little close to the tps. The whole is also slightly larger than what I need at 3/8" the recommended drill size for the 1/8npt tap is 11/32. I will see when the kit shows up.
