Ed,

I am rebuilding my 2.2L 911T engine, and intended to re-ring the pistons, not trying to upgrade the engine.  Most of the literature I've seen recommends not re-ringing.  New pistons and cylinders are NLA, PN 911.103.914.01.  E pistons and cylinders are available 911.103.916.01.  Can I use the E pistons and cylinders with the Zenith 40TIN carbs, without chaning the cams or making other changes and still expect acceptable (T) performance? 

If the T pistons and cylinders are within tolerance, and the clearance in the top land is less than .004"  can I simply re-ring the pistons?

Thank you, Ed Anderson
