If want to mod car then don't think about FC.....you really tried everything on your car or not??? there's so much DIY in the DIY section. How many did you try doing?
Not trying to be harsh on you but keep complaining how shitty is the car won't get you anyway. Car got problem FIX it! car can 't perform? mod it to perform! Engine is engine the figures and workings are all there. We humans got ideas and knowledge to make things better. It's a god given gift so use it. Expensive you say is because you haven't search around much yet to get a good deal. Even better if got balls DIY at home. Make mistake nvm, learn from it ask for help. I also learn new stuff when I DIY install my adjustable had some minor hiccups so what...fall down already stand back up. Performance parts don't have fabricate own self la, tools don't have? improvised. Go hardware shop buy tools. I buy new tools more than buying shirt for myself.
Mine is not BLM is FLX. Engine wise it's the same except for the gearbox and the intake module is different. Mine is IAFM+ with Getrag MT gearbox.
