Dave1647545494 Posted November 17, 2004 Report Share Posted November 17, 2004 reringed the turbo donkey 2.2L chrysler 9.5.1 comp TRW heavy duty rings I can get the boost as low as 4psi to break it in anyone have a recomended mileage with an n/a car I just let it idle with changing rpm for 15-30 minutes and then go beat the shit out of it for about 40 miles making sure to constantly vary rpm with the added cylinder pressures from the turbo its probably not good to break it in that way though Quote Link to comment Share on other sites More sharing options...
SHIEF Posted November 17, 2004 Report Share Posted November 17, 2004 Just run it for awhile and take it for a decent drive (like 40 miles or so), then you'll be good to go. Since all you did was ring it, it's not like your breaking in a new built engine. Quote Link to comment Share on other sites More sharing options...
Browning Posted November 17, 2004 Report Share Posted November 17, 2004 yea but I'd change the oil, after the 40 miles or so! Just to be safe, no sense in taking chances, ya know? And if it were me I'd do 100 miles, be safe! Quote Link to comment Share on other sites More sharing options...
Rotarded1647545491 Posted November 17, 2004 Report Share Posted November 17, 2004 Damn you piston guys. We have to go 500 miles under 4k rpm, and 1000 miles before boost, to seat the apex seals properly. Quote Link to comment Share on other sites More sharing options...

iwishiwascool Posted November 17, 2004 Report Share Posted November 17, 2004 Actually your N/A strategy works well for turbo aplications as well. Dont run full boost obviously, but increasing cylinder pressure will create the proper linear force and push the rings against the freshly hashed walls and create a nice seal. Immediately after my build up, I allowed it to warm up with varying RPMs then drove directly to the freeway for 3rd gear pulls @ 17psi. I now have a very good seal.
