e34stx Posted January 1, 2023 Share Posted January 1, 2023 Hi everyone, first time post, so hi! i’m after some advise so please bare with me. I’m looking at buying a WRX STI, either a bulb or a hawk, I intend to do a project build over a couple of years but I’m unsure to get a uk or jdm spec. The car will be used for fast road, maybe a little drag and the occasional track day. I see the jdm has forged internals etc and appears to be a stronger engine. I read through the performance guides above, do these guides also applicable to the forged jdm engine etc? thanks for your time. Quote Link to comment Share on other sites More sharing options...
