Kram, TRK, Thanks to you guys and various others on the forum I completed the mod in 3 days. The biggest hurdle is infact the 987 airbox install. Just took a spin around the neighborhood and although the ECU is still probably adjusting it was a spirited run. Seems to be missing just a bit of gusto off line but maybe that is due to the elimination of the Hemholz chamber. Other than that it is returning favorable punch throughout the rpm range. It seems to be more linear in performance now. To the other wrenchers, this is definitely a cost effective way to add some power, yes there were moments of disgust and a lot of cussing but in the end all worth it. Persevere and you will be rewarded. Make sure when disassembling the intake runner mani to cover the openings so nothing falls in. The AOS connection that cuts thru the runners can be connected from front engine access too. Just one more thing, the Aos connection on new dist-t is in a different position. I made the Aos connection there but disconnected at the Aos and ran a short length of tubing to connect the extra distance the hose needs.
