1) A dyno is used to measure a car's horsepower. That's as simple as I can describe it.

2) A lot of "garages" won't touch the stuff, usually you will have to find a performance shop to do it.

3) J-spec (JDM) is the original Japanese made and run motor. Simply put, J-spec or JDM is better than their american brothers.

4) Stainless is the type of metal they are made out of. This metal won't rust or corrode like most other exhaust parts.

5) Find a Lude specific kit, which there aren't too many. Holley's NOS brand makes one. Most of the time the nitrous oxide kits are universal, and have detailed instructions, but not prelude specific. Someone in this forum has to have info on it, they will reply eventually.
