We recently had a customer that had a 99-00 Civic Si that was consuming oil regularly. about 2 qts a week. We determined it was his rings that were shot after 120k miles, opted to rebuild it. while we were in the motor we decided to throw some CTR pistons in the mix.
Mods:
B16a2
Stock BORE
CTR PIstons OEM honda rings
DC USDM 4-2-1 header
ApexI World Sport Exhaust
VAFC Tuning
ACL Bearings

Now a bonestock civic si dynos between 130-135whp. A bone stock GSR makes 145-150whp. His baseline with the shot rings was 127whp. thats a SOLID 23whp gain from PISTONS only. The factory hone was still present after 120k miles, so NO MACHINE WORK WAS DONE. more proof that honing is NOT NEEDED if there is still cross hatches, motor doesnt burn a DROP of oil.
Next we are gonna do ITR cams and possibly an AEBS manifold an see if we can push it to 165ish.
