ORIGINAL: cincyTT

You could move it further down, but by making the psi 7 or 15psi, your not going to want to change it. You can then use a mbc/ebc to change the boost. The 14 or 15psi spring will just keep the wastegate from opening a tiny bit longer for a little better spool, but not all that major on a small turbo, bigger turbo maybe. Think all come with a 7psi spring installed. Its not really going to be an issue since the stock turbo runs off a 5psi spring and as you can see you can run 20+psi w/o problems
well limp mode is a problem [:@]

but if the spring makes that little change then i might as well go internal and save the headache of fitment

im hoping it wont be way too tight there.

What does limp have to do with anything? Like i said before, if you think you will ever upgrade, the external is the way to go. Also fitment isnt going to be a problem since there are plenty other people already running this style setup. The wastegate should be somewhat easy to access from under the car to where you can remove it by itself or with removing part of the exhaust.

fitment is my only concern, and by limp i didnt realize you were talkin bout the turbo system producing 20psi rather than the chip allowing that boost, cuz my chip wont allow it and throws me into limp right away... unless i have diode as well.

Fitment wont be a problem. And when you get the tune, you can run whatever psi you want from wastegate psi to 23-24psi on pump and maybe 26-28psi on 100+ octane or w/m.

I can get 93 from just about anywhere in Ohio and some places sell 92 and one place sells 94 and sometimes 100 octane. Places with more pollution controls like cali you can only get 91.

If i swap in the AWP ecu, i can run E85 due to the wideband. But i would have to run a mix unless i get more injector since it takes about 40% more fuel to make it stoich. But it is about 110octane and around $2 a gallon

Yes, the late 01+ 180's are AWP (02+ in a VW) and they all have vvt and wb o2's. TheBEA 225's have vvt and wb o2's also. The AMU's dont have either.
