i would listen to these guys on nabbing the b18c1 instead of the b18c5. First of all it will be huge to be able to convert to obd-1 as opposed to obd-2. You can get an LSD and alot of nice bolt ons and make the b18c1 pretty hot. It is just not worth the price difference to get the c5. You can swap almost any b-series part onto the c1 (minus IMs), including type R parts or tons of other aftermarket options. As far as using Hasport, DO IT. it WILL save you time and eventually money as you will not be happy nor will other products be nearly as effective.
