How long do ka-t's useully last boosting 8psi?

[red s13]

I was just curious to see how long turbocharged ka's last boosting 8psi? I was wondering because I have a 93 s13 and im only boosting 5psi, but plan on turning it up to about 8 or 10 psi. I have read that some people have been boosting for years with no problems, but are these cars rebult or built up?

All depend on life of your engine. Some last a week, others are still running and been boost for yrs. Just depends on regular maintence and it's past life.

[red s13]

How long have you been boosting for and how much boost are you running? Oh yah how many miles do you have on your enigine and is it stock or rebuilt?

[Structure240sx]

alot has to do with the tunning

with a GOOD and decently safe tune being turbo will not shorten your engine life much if at all

its been said with 8psi and a good tune...your engine still has 90% of its normal life span...i read that in a book somewhere

ditto ****ing do

mine ran for 10 days at 8psi

[red s13]

Only ten days? What the heck happened was it from to much tiiming or a fuel problem or was your engine in bad shape to start with? I would be so if my motor only ran for a week and a half.

Mine ran for 9 months at 6psi on a 8:1 FMU and BTM, ran for 1 month at 8psi w/enthalpy tune, and has been running for 4 months at 11psi w/enthalpy tune.

Trapped 104.5mph at 8psi and trapped 107.4mph at 11psi.

sunny i beat you...my 8.6psi ran for 2 days....125 130 100 125 compression

[sunnys14]

your 3rd cyl was low also?? mine too!

[Craving4Boost]

lol uhh i think they're all dangerously low...but yeah 3rd cylinder is definatley the worst

hmmmm mine ran on 9 psi for 2 and a half years. i had 76K miles when it was first boosted and now it has 120K miles on it. just did compression test 2 weeks ago and its still mint. and i've been running 14 psi for 2 months prior to that. the engine has never been opened.

If you want longevity you need some sort of ecu tuning (jwt or enthalpy) or spend some money and get a standalone and have it professionally tuned. No ands, ifs, or buts. Do it right the first time and give your engine a shot at life...lol
