My new downpipe came yesterday, FWI from TDC (member here) is coming today. I will be sending the stock downpipe back to ZZP for a $50 credit towards their PLOG. I already did most of the maintenance items, flipped my dogbone (free mod), and put in a 180* thermostat while I was flushing my coolant. I will be doing the Seafoam clean (not the part where you put it in the oil, but the rest) and will at that point go to Autolite 104 plugs to go with my newly installed plug wires.

That will get things breathing right, and running cool. Then I will look at putting a 3.5" pulley in and getting a PCM or a tune if I can find someone around me to do it. I could probably go to a 3.4" if I had more than 91 octane fuel around me, but I don't so I am staying of the safe side. Besides, this is a daily driver for me. No plans of racing or anything, so that is far enough for me.

you cant just put in the thermostat and have it work, you know that right? blue, did you touch upon this in your thread? i never really read the whole thing so im not sure.

YOU CANNOT JUST PUT IN A LOWER DEGREE THERMOSTAT AND HAVE IT WORK! YOU NEED TO TUNE YOUR CAR SO THE FANS TURN ON AT A LOWER TEMPERATURE AS WELL!

Nope. If I knew that, I wouldn't have done it. I was following the first "Step 6" in bluegtp91's thread where it says to do that as a "maintenance" item.

I saved the 195* t-stat. Looks like I will drop that back in and save the 180* until I can get a tune. That thread really should be changed...


So what will happen if I drive the car 10 miles in the morning (mostly highway) and 10 miles in the late afternoon before swapping it back for the original? Or do I need to make a point of doing it before that?
