NO NO NO NO NO NO NO!!!!! A k04-001 is exactly the will bolt up exactly the same as a k03s. You wont need lcr injectors or a 4 bar fpr. Its not a k04 from a lcr, tt, s3 etc its a totally different turbo also with the prefix k04 but is basically the same as a k03s. It will not make 270bhp. Just get a k03s. K04-001 is not worth it at all.
Ah right sorry mis-read. He's looking at 240 then? Isn't it highly recommended he does have a 4 bar FPR if he's running a stage 2 though? Looked at my receipts and my KO3s was £220.
