    NA is best - 3.1L M20 w/ ITB's

    Finally pulled the trigger on the one modification I've been eying for years - individual throttle bodies! Picked up a kit from RHD with the new airbox. I'll be putting it together between Christmas and New Years, almost finished gathering the last bits and pieces I can think of before the holidays. I'll also be changing the camshaft out from a 272 to a 288 and swapping the IE rockers for MM ones. The plan is to complete the cam change and install the throttle bodies in ~3 days, then figure out the actual air filter situation afterwards. I'm going to keep the Miller MAF and WAR chip setup as opposed to an Alpha style tune using MS... guess we'll find out if it works haha.

    Car as of yesterday, yanked it from storage already in preparation.



    Current engine evolution: 3.1 stroker with built head (oversized valves) completed a while ago. Looks like the host went down and took most of the old pics with it. :(




    It's been a few years now and it's been great, but I've fully decided I'm sticking with the raw NA side and going to push it as far as I can. Went with a 42mm RHD kit since the engine is larger displacement.







    Picked up a set of 17lb injectors as well and had them rebuilt, I'm not sure the stock setup will be sufficient and I'd like to bump my redline a bit afterwards.

            already got a chub over here thinking about it.

            I also fantasize about doing this with my M52.

                As far as I am aware, you will be the FIRST ever 3.1L stroker M20 using RHD's kit... will be very intriguing to see the numbers when it can breathe a little better!

                  According to Rama, it would put my 2.8 right around 250whp!
