The euro S50 is what- 315hp?  If an M42 is set up to be basically 2/3rds of a euro S50, wouldn't breaking the 200hp mark be readily achievable?  I have an M42 on a stand here, along with the complete driveline to put it all in my 2002.  I already have an M47 crank, so top end work including itbs is part of the plan.  Megasquirt is local to me so that is a goal as well. It seems to me, at least with regards to runner length, that these itbs are more properly-sized than the euro S50.

I take it you're in Atlanta as well? I bought all of my Microsquirt stuff directly from DIY Autotune and it was nice to not have to worry about shipping back and forth. Shoot me a PM if you're local, as I've also got an M42 2002.

I don't have any experience with the stock exhaust system as my 318is came with an 2.5" aftermarket system when I got the car. I can say that for a stock engine, the 2.5" is definitely too large. I've been playing with different layouts the past few weeks and found that the 2.25" is much better suited to an internally stock street car. Bottom end response is much improved and by going by the mileage displayed on the econometer, it takes the engine much less effort to get up to speed. The upper end of the rev range feels like it may have suffered a little bit, but that's probably placebo because with the oversized tubing there was no bottom end power and then it suddenly jumped into the power once it hit 4-5k rpm. I wouldn't be surprised if the stock exhaust was much more restrictive, but I'm not the person to be able to give you any factual data in that respect.

Looking forward to seeing this kit go up on the market. I've been debating between Rama's kit and the Dbilas race kit, but I've been wanting to see what kind of results you guys end up with and what the pricing is going to be like. Also looking forward to seeing all of your findings throughout this process if you're still planning on publishing that.

Very nifty. I've been going back and forth on what the best plan of attack would be for ignitors for my Microquirt unit, and this may be the ticket. Are the coils secured in place in the pictures?
