I am in MN on the north side of the Twin Cities.
This a completely stock motor with the only mod being the turbo. I have the AEM EMS for tuning. As it sits right now boost starts at 2000 RPM and is at full boost at 3500 RPM. Motor made 300WHP on 7psi. The guy I bought it from said its a VERY conservative tune. I plan on hitting the dyno this spring and having it tuned for 10psi.
I have been building and driving turbo Hondas for about 8 years now and the whole idea of having to lower the compression ratio is not really true anymore. Its all in the tuning. If you plan on building a big HP motor then go ahead and lower the compression ratio a little. I have built low compression high boost motors and the do make more peak HP. If you plan on driving the car mostly on the street or doing some autocross, then I would suggest you go with a low boost motor with the stock compression. If you lower the compression ratio the car will make less power than stock until you start boosting. When you do mostly street driving, you are not boosting or boosting very little. You really notice the loss of throttle response on the low compression motor. I will never build another low compression motor for any of my daily driven cars. There are many ways to build a turbo motor but the one fact that you MUST follow on any of them is spend your money on good engine management. This will prevent many of the problems that people have with boosted cars.
Good luck with you build. Once you go with boost, you will never go back.
