Did a tune up this week with new plugs, 8mm wires, 02 sensors, cleaned/flow matched injectors + a new CA legal 'Challenger' Hi Flow cat and 'R' Speed Check valve. The car was alot quicker with just the new cat and the tune up. I went with an SMSP 'Challenger' ceramic cat after some esearch on high flow cats and the challenger model kept coming up as the best flowing. I used to think Random Tech made the best cats. Well apparently the SMSP Challenger cats outflow those by a bunch!!...alot better than Magnaflow as well. Better quality by far too. Cost was 120 bucks + shipping. A steal compared to the 300 Random Tech wanted and that wasn't even CA legal
Made by SMSP the cat is a 300 cpsi (cells per square inch) ceramic unit and after 300 miles has not thrown a cell. Instant difference in power. Especially right off the bottom bam:biggrin:. It's not a metal cat and is comparable in size to the stock cat. Placed exactly where the stock cat goes (important for cels) using stainless steel and we helped flow by eliminating alot of the stock bend.
R speed check valve was added along with new 02 sensors today and now the car runs close to perfect ( barely bouncing idle lol) and is considerably quicker than before woot:tongue:. Pulls nicely from an idle
Adding the 02 sensors 'calmed' my idle down. Still bounces a little (not crazy like before) and I don't stall at lights anymore. Steady. Prior owner told me yesterday not to waste my $$ on 02 sensors and that they were fine. Records showed they were last replaced appx. 40k ago. Biggest help so far in my quest for a normal idle and Im sure glad I didn't listen to the ex owner about the 02 sensors or I'd still be looking for a better idle. Props to 'Father' by the way for his suggestion on the 02 sensors
