Has anybody pass smog (Nox reading) with CTR pistons in their b17a? I got hit with a “test only” test. My smog is due very soon. I want to make sure that it will pass. I was going to get a pretest but not sure if I need to. My smog setup will be
2 layer headgasket (have a thicker .54 cometic if needed)
stock header, stock ecu, stock air box, stock cat
7’s spark plugs
will set timing to 14
will overlap sk2 stage 1 cams +1 -1
I will toss in some cheveron techron this week to clean up carbon buildup. I will probably throw in some HEET before the smog test as well. I have a stock fpr but it was “crushed” to increase fuel pressure. Any ideas if I will have problems with NOx just because of the CTR pistons? Any advise will be appericated.
The idle in Washington can be up to 1100. I’m glad I don’t live in Cali. Here is my setup.
skunk2 stage 2 cams
mugen thin head gasket
skunk2 computer program
typr r intake
greddy sp exhaust
fuel pressure set to 40psi
fields vtec controller set -15% at idle
timing at 12 btc
