www.maxrev.com has a turbo kit for the D17 01 and up SOHC civics. It is actually one of the better ones I've seen on the road. It utililizes a hybrid T3T04 turbo with a 48 trim, I think.... not as big as the preferred DOHC T3T04 application. The blow off valve is made by MaxRev themselves which I think is almost similar in sound compared to a turboXS RFL... loud as fuk! That doesnt matter anyway since you can choose whatever BOV u want. These are the sounds that you are talking about
