i was wondering what the stock psi was and whats the most psi you can run on the stock turbo?

stock is 5.5psi



max boost is around 10 psi with proper fuel management

mine has some mad free-flowing exhaust and i spike up to 8 psi when drop into 2nd



other than that, mine hits around 7 under hard acceleration

10 on stock ecu, correct?

yeah 10psi on stock ecu. you can go higher but the stock turbo isn't happy and starts puking oil short thereafter. ask me how i know https://www.nopistons.com/forums/pub...#>/biggrin.png

how do you know?

i had oil dripping off my hood https://www.nopistons.com/forums/pub...IR#>/bigok.gif

LOL vosko. You'd be the one to try too. How many rotary's have you killed! lol

honestly the only engine that i caused its demise 100% was my turbo II and i couldn't expect too much the TII i basically brought that engine back from the dead https://www.nopistons.com/forums/pub...#>/biggrin.png

yeah you have to say that we can only give vosko partial credit for blowing up one engine, thats pretty good considering his track record

thanks for the input... im new to this whole rotary engine thing...i just bought an 87 turbo two with 83000 original miles on it....it was stored for winter...nicest car ive seen in a long time

did you buy leo's car from PA ?

no im from maine, i found this like 2 hours away from my house...it was def worth the drive let me tell you....i couldnt beleive my eyes. It was a geand father that owned it, he said he didnt want to sell it to a kid but my dad and i covinced him and thne before i left he asked if i was a smoker and i said no.. he said " good because i wouldnt have sold this car to you if you were" its a really nice car

get some pics

ill try too... my friend has a digital camera so i'll take some

10 psi out of the stock turbo is the max? My friends turbo II is running about 14... and has been for quite some time

also thought the limit was 14-15 psi on the stock turbo

I've been hitting 14 - 15 psi in 4th and 5th gear, no problems. My turbo was shot before I did exhaust and FMIC, and has not gotten any worse. I wouldn't recomend a TII with ONLY full exhaust running 14 psi, the engine wouldn't last too long. As for me, I very rarely hit 14 psi because I know it isn't the best for the engine/turbo. But when I plan on getting high boost I run it super rich with the SAFC. I need to upgrade to some 720s though, I'd feel alot safer.

bah! boost it to 20! It will work fine! https://www.nopistons.com/forums/pub...IR#>/wacko.png
