Hi Guys

Right after my last post regarding my engine spec shopping list Matt Lewis has come back with some good prices BUT i wanna make sure im getting the right stuff as back in the 90s we used to stick a massive turbo on and a adjustable boost valve and off we went

I would like to see 400bhp at the wheels so going for full engine rebuild with uprated bolts, bearings, 0.5 oversized pistons, group a gaskets etc also thinking airtec alloy rad & 60mm intercooler with siemens 55lb blacks and gt30 turbo, 3 bar map sensor, group a induction, uprated inlet cam, verniers, & a map by someone in the know! Do i need to do anything regarding the ECU?

Any help on this would be most appreciated
