I have a 96 carib, Black top engine. Have a trd filter at the moment. Trd extractors and 2" exhaust, Split fire spark plug leads and plugs. Have also got a splitfire earth set up which is supposed to earth the living hell out of the engine and produce a hp or 2.
Me brother "thinks" it has beed chipped as it pulls harder than his 2L turbo Bluebird. I dont know how to check this out tho.
