Quick history of how I ended up with my current project. I had a co-worker, whose son had developed epilepsy and had to sell his 02 EM2 Coupe. Here is the caveat I have never built out a Honda engine of any type, and ended up with an extra engine out of the deal. I ended up with a JDM D15B 3 Stage Vtec out of a 99 Del Sol Si. The transmnission that was married to the block is already married to the D17A2 which has 194k on it. Current engine was rebuilt less than 10k ago so I am not pressed for time when it comes to putting the built out D15B under the hood. Yes I know about the P28 ECU so I can chip it out and I do know about building out a mini me. Personally I would love to keep it a D15B block with the D15B Three stage head. I use this car as a daily driver and commute over 120 miles a day. Any advice to keep this little engine NA and over 170 hp would be appreciated.
