Mileage when boosted

i was wondering at what mileage any of you turbo guys decided to boost? and where are you now? How long? any problems so far?

i boosted at 278,000km,compression was 180 on all 4 cyl and motor made no much if any ticking/knocking sounds… didnt burn oil(belive me or not) and had no problems, sold car with 320,000 and she still driving

how much boost?

started at 6psi, drive around for a while, then i adjusted it to 11psi, and had it like that until i sold it

Boosted 6psi 129k - 135k. Motor is apart now but it was very healthy. Low boost and a proper tune is the key and it should be plenty safe.

92 teg with 259,000 miles that’s right 259,000 miles
t3 turbo 14psi tuned on crome
compressions 1~195 2~180 3~185 4~195
no problems with motor so far but i’m doing a wire tuck so car will be down for a while.

Did any of you guys have E85 with your boost set up?

16x,xxx miles boosted till 21x,xxx miles on a super 60 t3, drag gen III style kit. 170-ish across the board when the kit was removed. converted back to NA and drove it another 15k miles till the city came and towed it away (not telling me where it was till after it was sold!). that was my last db1, almost 5 years ago.

stock b18a 300whp at 18psi from 150 000km to 152 000km. wanted more power so threw that engine out and built an ls/vtec.
had 185psi in all 4 cylinders after the short period of boosting. did burn a lot of oil however when i did boost. around 1 liter for 400-500 km of boosting.
