    OK finally got it tuned on alpha n to the point where I can drive it anywhere, at any temp, and as hard as I want. never excessively cranks and idles rock solid. Runs clean, easy to daily in stop and go and lots of fun in the twisties. However I hate the downrev with the kooks race muffler it sounds like ultra beehive diarrhea rasp between 5k to 3k on the decel.

        sounds amazing, why did you go with the Kooks muffler and was it the oval or bullet style? did you consider cheap turbo style mufflers?

          that looks like it would be more fun in the twisties now seeing its not trying to step out every time you get on the gas. More of a chance to ring its neck now

          sounds excellent

            I just got it on sale at summit. It's the bullet style around 18" long I'd say

                      Still running flawless, made some trips up past 8k elevation to get barometric correction dialed in perfectly.

                        just read through pretty much this entire thread, and everything is just purly impressive. i would love to run ITBs, what is your current set up? And are you running a Cam? Id really like to run RHDs roller cam conversion, although this will still be a daily driven car, so i feel as though the 306 cam is way to hot for stock application, same as the 292 cam, any thoughts? Ive also considers running a 2.8 stroker with these, just want a nice pump in power, also, what engine management are you running? sorry if some of this has already been answered, keep up the awesome work!

                          It depends on how many cubic inches and the static CR you have and how streetable you want.

                          A stock 2.5: with 8.8:1 won’t really like a big duration cam. With ITB and standalone IMO you could actually use the 292 and drive on the street but it’s just far far away from optimal (most wouldn't say its a very streetable but thats kind of an ambiguous statement) plus you need to worry about clearances.

                          I’ll be using a 292 on the street hopefully before years end but that’s with more compression and alot more stroke than most engines so the cam acts smaller than it does a on low compression 2.5L . I decided against the 306 as I didn’t want to hurt the power right at the bottom end like around 2000rpm too much. I may end up there in the end depending how the 292 goes.

                            Just a quick test video of my roll bar mount. Loving this itb setup so much. Enough power to play around with but nowhere near enough to send me sideways off a cliff.
