If you look where the AC drain is in the fire wall that could easiley be opened up. You can get a drill on the back side.

With so much vacumn line running everywhere it will make your boost controller not as effective... Correct me if i am wrong

Depends on the boost controller. Some of the fuzzy logic ones will anticipate the slow response and start acting early. But I don't think the difference would be to bad between that and an MBC in terms of response.

Take a look at the Hallman remote MBC. Great product, and the MBC is adjusted by a cable so that the hose is kept short. I believe I paid around $140 for mine.

Another option: T in a bypass circuit with a solenoid.

Another option: T in a bypass circuit with a solenoid.

Switched off, it bypasses the MBC & holds boost to 5 PSI.

Switched on, it closes the bypass & uses the MBC.

It's simple, reliable, & runs on one wire.
$35 including the MBC.

pfffffffftt response - shresponse, plumb the thing in there and be done with it.

I beleive your best bet would be beside one of the A/C evaporator lines as mentioned, you can access the back side of the lowest one without taking anything apart.

Hey that isone sweet setup you've got there sureshot!! beats the heck outta my slick old school RB in-cabin......I like the fact that you can go right back to stock boost without messing with the MBC settings.

It will work with any turbo vehicle.
When I did the vac simplify & emmissions removal, I kept the old solenoids.
When I hooked up the MBC, I just used one of them & capped its vent.
All my modification wiring is passed through the former ABS harness hole.
The switch is a hooded safety switch from a parts store.
The label was made on a Brother label maker.
