I don't think you will pass the Colorado emissions test with a turbo. Not sure about that; just something you should check out.

There is an intercooler option from LHT. He has posted a lot about it on Honda-tech.com and in the "forced induction integra" forum on hostboard.com. It sounds good but for some mysterious reason there have never been any dyno results posted. The JR water spray system doesn't improve power. If you have hondata to control the fuel and timing then detonation will not be a problem. In that case I think the water spray would be a waste of money.

The one thing that I am CERTAIN about is that you should go with th 10-11 psi from the very beginning. With the hondata it will be very safe, and you WILL want that extra power. Since the basemap you get from hondata will be preset for a certain boost level then go ahead and get the highest. I had the stock (5-6 psi) jrsc on my R for less than a year before I paid for the boost upgrade.

The only other suggestion I have is cooler sparkplugs. You should also order an extra belt for the blower. It is a simple job to replace one if it brakes, but it could take a while to get the part from JR. You can buy the belt at most any local autoshop, but JR won't give out the part number. They want you to buy from them. My car was boosted for over 30K miles before I had any belt problems.

You will also want a better exhaust system with all that boost. It will make a world of difference in how the car runs.
