Hi all not long obtained an absolutely mint 93 wrx in black. it's soo fresh the mods I know of are a kakimoto gt1.0z exhaust I think it's titanium but haven't had a proper look. is there a way to tell the difference between the titanium and stainless. I've never dealt with titanium befire so don't know what the difference is. decathlon, td05 turbo, apexi cone filter, turbo timer, UK 2000 4 pot callipers been told it has uprated injectors but not 100% on that and I think fuel pump again not 100% sure. I'm not sure if there's anything else admittedly I should have paid more attention when I bought it but all I was interested in was how clean it was lol. it was on the rollers end of January and putting out 310 at the flywheel. I'm looking to start making more power safely what's the next step I've heard the box's aren't good for much more power was considering a straight cut but very expensive don't mind the whine though. Where should I go from where I am? I aim to make 400+ and stop there will I need forged internals and what mods will I need to get me to the 400 mark thanks for reading.
