I know this has been covered a few times and after I've had a read of other posts it's still not clear to me how I can get around the emissions test, I've changed my engine and turbo since the last mot it's a sard k24 turbo with decat pipe external wastegate! I've read I can have a pre-cat emissions test because it's imported and was never made for the UK market the only one that I know of that was maid for the UK is the starlet gt mk1 witch is pre-cat I just want to know where I stand and is there any tricks or tips for passing emissions? I've still got the old turbo set up but don't want to have to change it over!
