Turbo Technics did!
THis what your after? im coverting my RS1600i to Turbo technics, running between 4-7 psi on standard block, with stage 3 head, hot cam and other mods

Was going to go for big ZVH power but i want to keep the twin coils and havent got the ££££££'s to develop an ECU to run them on anything other than the 16i engine.
