I intend fitting a TD05 fron entry modified on my Sti4 engine. As this is a rally car and has to have a 34mm restrictor , 50mm away from the turbine blades, what sort of power can I expect? Is this mod worthwhile over the standard VF24 with a restrictor? The car runs on GEMS with a K/N filter in a cold air box, no MAF and a 3" exhaust system, no cats. Will I need bigger injectors? I currently have a fabricated alloy tank with external Bosch (Audi/Porsche?) pump. Standard fuel rails, and regulator, modified with -6 fiting and pipework.

Thanks, any comments gratefully received!
