Turbo advice TD05 20g on 2.5 STI
Hi,
I'm after some advice on whether a TD05 20g (Andy Forest turbo) would be a worthwhile upgrade with associated remap on my STI.
Car is a 2006 STI, forged engine (pistons) from Dan at Surrey Subaru Specialists plus upgraded gaskets, bearings etc. Got an uprated panel filter and Perrin intake hose, 2nd decat, standard bore de-resonated centre section and prodrive back box.
Can anyone have a guess at what bhp/torque I could reach on this set up, and whether there would be anything (fuel pump, downpipe) that would deemed as essentials other than the obvious remap.
Cheers,
Andy
