I have a pretty good idea I think how to get forced induction on my car however I have a few questions seeing as how i have never used a tubro before.

1st how do the vacuum lines work in a turbo'd car? I mean the brake booster for example runs off of vacuum from the air intake. (neg pressure) how would it compare to using forced induction (pos pressure). When a guy installs a turbo can all the vacuum lines/ sensors ect stay intact or do you have to do anything special?

2nd what is the best pressure for a healthy ka24de in stock form to run as a daily driver?

3rd does the MAF have to be moved to after the turbo or can it be deleted with a work around?

any info would be helpful.

thanks

For f*** sake how about " welcome to Nico"! These are good questions that even people that have been on here couldn't figure out. As far as the brake. Booster there is a one way check valve ( already there but would check to make sure its working) on the fire wall to hold vacuum /prevent pressure. T off fpr. Vacuum line for bov and run a line from intercooler piping. To wastegate (unless you're running a boost controller which I wouldn't rec on stock motor) I would only run 7-8 lbs on stock motor/fuel system (which is what most internal wastegates open at ). As far as the maf you can put it before or after the Turbo called blow through. Most important get your ecu sent off to E-mance, jwt or enthalpy. For a fuel/Ignition map for your mods. Be aware the stock maf maxes out quite easily.
