Well took my BLACK 85 SUPRA back to emissions and passed with no problems after modifying the exhaust to fit the larger 17" cat compared to the 12" cat .Time to place straight pipe back in and save the magic cat for next test 2 years from now.


BEFORE CAT GHANGE
HC 1.6146 GPM MAX 1.800
CO 7.7911 GPM MAX 30.0000
NO 3.8769 GPM MAX 2.800

AFTER CAT CHANGE
HC 0.0207 GPM
CO 0.1348 GPM
NO 0.0207 GPM

well i just had the hear port and polished, 3 angle valve job, new valve stem seals. I cleaned that tube that goes from the back of the engine to where the intake manifold. I also cleaned (maybe not as good as i should of) the whole intake manifold and that thing that says EFI + the EGR system too.

I even posted pics about my engine and head

It seems that the outside of the engine is cleaner that than the inside :roll:
