timing for 9.5:1 compression EA82T


Recommended Posts

just wondering what timing i should run with my EA82M (Mongrel) engine.. everyone has been telling me that it wouldnt run right, if at all. ive already done a 3 mile run up hill holding 6 psi boost the entire time and it never leaned out, i have my original timing for now cuz i dont have a timing light yet (22* or 24*)

 

i have 02 readings in car at all times and havent had any problems yet

 

runs perfect, just have to finish up my vaccum system now!!

 

thanks for the help!

a fella a little south of you ran his unknown origin EA82T with similar compression at 10 DBTDC. Some time later car was for sale with suspected blown big end. Dunno if you will get same outcome, or if a rebuild known engine would do same ,,,

 

way to go  !!

ive already been tearin this engine up, i shift at 5 or 6k every gear HAHAHA havent had any issues yet.

 

MPFI block, vf11 turbo, 3rd gen heads w/stage 2 delta turbo cams (14k miles), and slight porting n polishing. seems to do fine @10psi with the stock ECU

 

you probably boosted it too high.. im running 10psi and it doesnt lean out at all, all the way up to 7500rpm. lots and lots of bottom end torque and still pushes top end power pretty good

 

 

thanks Jono, im going to adjust slightly until i like how it runs (: i rebuilt everything in this engine.. smoothest running EA82T ive heard yet haha

Less than stock.

It is more about avoiding detonation than air/fuel ratios.

How are you monitoring the knock sensor?

There is a reason turbo cars come w/lower compression.

You should run the highest octane you can get.

I expect it will run fine until the meltdown.
