Should be straight forward enough, go for a low comp CVH bottom end .5 oversized pistons with them machined to match, prob skim the crank as well if it needs it, then go for a big valve head conversion, ported out, matching inlet, cam to match, stage 2 turbo, chip, uprated intercooler, and u should be able to run 20psi + boost and easily see 200bhp.

You can save money on the head, as u dont need the big valves, i would get it ported, and get some new standard valves and guides if it needs it! As you might as well do everything to it while its in bits... plus ud better put all the usually stuff on cam belt and tensioner, water pump, oil pump etc..

As above u dont really need steel rods if ur aiming for 200bhp, i say steel rods are a must if u want to hit the 260bhp mark on a T34 turbo or something...

as for managment its up to u the EFI is better to map but i like the simplicity of the MFI metering head and a 5th injector!
