there is a bit of confusion when doing a sr20 mod into our little cars due to the power to rate ratio but it can be done....But if you can get an engineers report over here for it you will be able to get it licenced here but you will have to go to welshpool and talked to the guys in transport and dicuss it with them and they will give you a direct answer. The guy to talk to is Clive i think, he is the most helpful....if there is such a thimng with the dpi.
Good luck
