I am running a stock z6.What would be a safe psi range to run on it having 150,000 + miles?I searched everywhere on the forum to find this info but nothing.

Depends on turbo, condition of the motor, etc. Do a compression check to make sure it's healthy and go for it. I was running 8.5-9psi on my 15g on a block with 195,000 on it.

i wouldn't turbo my car without an intercooler. even if i had to use a dsm sidemount it is better than nothing and those are very cheap.

Like mentioned above, do a compression test and shoot us back the results or just search the site for what the compression test should say....

"Base 4-5 psi..." Please dont turbo the car with one of those eBay ecu's/chips...Take your only transportation to a dyno and have it done correctly with ppl who do it on a daily basis....

Stock Z6's i see upwards of 11 psi but thats just me and our tune sessions...your stock MAP sensor will read 10.7, which is enough for roughly 200-215 wheel (depending on condition of block and tuner's knowledge of course)

Case and point, before you slap ur turbo setup on the car - drive the car to a local shop/tuner/dyno and ask Q's about a tune session and what they like to use on Honda setups....

good way to put it... I am at 11lbs on my stock y8 motor and it has been running like a champ... and thats the y8! lol as long as you have a good compression... you change the oil(use good oil) all the time..... you should be fine! Good luck!

Awesome thanks for all the help.What viscosity oil do you guys recommend?And to make up for the oil return line and turbo shouldn't I put in more quarts than the stock recommended amount?If so how much?
