Hi all,
I've had my 99 gf8 wrx for a month or so now, which has mainly been spent undoing some very questionable modifications and generally tidying it up. I know most of my questions will have been asked countless times here and everywhere else, but I'm not sure where to start learning more specific things so even any pointers on where I should be looking would be much appreciated.
First off, I've noticed that at times, according to my gauge at least, that my boost will drop about 1psi. This seems to go away when I get in it the next morning and it truly has me stumped. Any ideas what I should be looking for? (gauge normally shows 11.5psi, after I removed the .9mm welder tip crammed in what I think was the wrong side of the tee with the factory pill still there.
Next, I have a clicking CV in the rear and no shop that I've spoken to can track any replacements down. From what I understand this is pretty rare so I'm looking at going for second hand shafts, so how much cross compatibility is there? Do they need to be from a hatch, can they come from a forester or something etc
Finally, I'd quite like to get a bit more power out of it as I can't keep up with my father in his type r. I've got a bogan mate who reckons that the ecu will be able to keep up with more boost and that I should be able to put an STI restrictor pill in it without any issues. Is this true, and what adverse effects am I going to see? I know absolutely piss all about that kind of tuning.
As I said, any other good resources anyone could point me to would also be brilliant.
Cheers
