    XelderX BG ITA Build

    It's time to move on to the next chapter of my BG Protege's life. It was retired early this spring from National Autocross competition where it managed Match Tour wins, National tour wins, multiple National Championship trophies, two National Championship podium finishes and one Ladies class National Championship. With recent rules changes I've moved all the autoX equipment over to a 323 Hatch that managed a 5th and 6th place trophy at the Championships this year.

    What to do with the old Protege? I don't have a title for it so it will remain a track only car. The next step is to take it club racing. SCCA Improved Touring racing to be specific. The Protege falls into the ITA class which puts it up against some real heavy hitters. Namely the CRX and Miata. Each car has a minimum weight it has to achieve which helps balance out all the cars. The Protege has to weigh no less than 2325lbs. Crunching some numbers tells me that I'll need to make around 150hp to be competitive with the lighter cars. I find it highly unlikely that I can squeeze that much power out of it, but people said the Protege wasn't going to be competitive in AutoX too.

    The first step is to get rid of the interior so the cage can be installed. That will be the main project for the winter. Here she is in the garage getting ready for the easy part....dismantling.

    150hp shouldn't be too crazy to achieve if you're willing to fork out the money...port matching/port work, a nice header, a proper cold air intake, megasquirt and some cams/gears should get you DAMN close to that. I know people who've gotten just over 130whp with the above mentioned mods, not including megasquirt or port matching/polish work.

      Cams and gears have to be stock and I have to run an unmodified stock MAF. It will be interesting to see what I can do with it.

          Motor internals must remain stock. You can balance/blueprint.

            No offense. But if you can't alter the motor there's no ****ing chance you can make 150 with a BP. Just not happening.
            What other options/alternatives do you have/can you do

              Can you use oem parts from other model BPs?
              Before you criticize someone, first try walking a mile in their shoes. Because then you'll be a mile away, and you'll have their shoes...

                Drive the piss out of it. And it's not 150whp...150 crank.

                  Only 1st Gen Protege motors. Compression can't be altered.

                    XelderX like you I started with AutoX and moved into road racing. I spent a few years in and around my regions SCCA road racing world. I can tell you from my experience almost everyone cheats. 99.9% of the top runners are jacked and many of the back runners are illegal as well.

                    Go all out with your suspension set up, and when you get tired of getting passed like your standing still, build your motor. There are enough experienced BP builders out there think of all those Miatas. Look into the shops building the motors the top Miatas guys are running; they'll know the tricks you're not going to find around this site.... sorry to say.

                    I'm sure the basics of Cams, head work, compression and more will be the areas of focus.

                    If I remember from my days in the Rules there was a legal allowance of a .5 (half) point bump in compression, a small bore increase maybe 60 thousandth max? Any cam from any car same model, same year or Older? or maybe it was same year or newer... this was 12-14 years ago.

                    good luck, it's a blast. I loved wheel to wheel a million times more than buzzing through the cones.

                      I dont really see how you couldnt run toe to toe with a miata. You should be able to meet your weight rating and the engine is relatively the same aside from compression. FWD has vics to help at least. Run some stock size miata pistons for the compression bump and who would be able to tell unless they actually measured them.

                          Thanks for the advice. I'm aware of some cheating. A friend of mine just bought a used ITA CRX and found at least 9 illegal mods, including a lightweight flywheel. I have an engine builder that specializes in Spec Miata motors. He will be taking care of my engine.

                            So you can get away with an OEM Tubular exhaust manifold?

                            Think you could get away with doing the exhintake swap? It involves cutting the disti drive off the exhaust cam, flipping it 180* and re-drilling the cam gear to fine tune the degrees, I believe it's a total of 197.5* (there's tons of links from the Miata guys though).

                            There's a lot of port work you can do on the intake manifold as well to gain a few whp.

                            Keep us posted tho, curious/interested to see how this goes!!

                              I could probably get away with it, but I'm not going to cheat. I'm not too worried about the motor at this point. Getting the car functional and on racing is the first step. Making it competitive will depend on how much further it needs to go.
