Hi, my 02 wrx was a lemon and im slowly getting it back up to par. But the Turbo set up is kinda wack!
There is no boost controller at all! 1 Line (the blue one) that goes from the wastegate to the turbo. So I bought a cheap ebay MBC
I just need a little bit of help and advise on installing this without blowing up my engine. I found this

But I have questions about the restrictor pill. If i even need it because with the current set up I don't think there is a restrictor pill. Pls help any feed back will be appreciated! Thanks!!!
