Build thread- 73 duster, forged 5.7 w/ PS and AC, 5 spd, big brakes and floater rear

Thanks for the reply.

I built my own MS3. I encourage anyone on the fence to give it a try. Soldering is pretty darn easy. I started by buying the JimStim and the JimStimX, these boards allow you to fully test your MS before you put it in the car. I bought the JimStim and JimStimX as kits and put them together first. This helped me build the confidence to build my own Megasquirt. FYI, the JimStim has a built-in self test, so you can test the tester. Pretty neat.

It took me about 4-8 hours to build the MS, but saved me close to $200.00, with the added benefit of learning some of the fundamentals of how MS works. Being able to fully test bench the MS when finished was an added bonus.

Your wheel and tire combo looks really nice. I think I'm going to run 245 40 18 in the front and a 335 30 18 in the rear. Although the rear tires are a lower profile 30 vs 40 they have a very similar sidewall height so it should look okay. The fronts will be 25.7" tall while the rears will be 26.0" tall. In order to fit a 335 tire I will be mini-tubbing the car.

As far as knock sensor. I haven't been hanging out over at the MS forums for a while, but last time I was there it seamed that Knock was still in beta. If its out of beta and they have clear instructions for testing it might well be worth it. That way you could enable knock sensing and get "free" HP just by dumping in some 104 octane fuel.

Keep us posted.
