wedsport is coming out with hubcentric center caps for the tc105x. i have a set for mine on order. i was told by @kamispeed they were coming maybe april/may ish. i think its listed on their site.
I know this information probably doesn't help much for this generation si, but I have the whole razo pedal set for my 93 si and it puts the gas and brake pedals practically on top of each other. I like them. But also my car didn't have aluminum pedals with grips factory.
This is an interesting question. I was talking to someone who owns a Harley Davidson edition f150. He has a tuner and a smaller pulley installed. He is trying to sell it, but it wont pass CA smog tests. Even though he reverted to the "stock" flash there are 2 monitors that wont set, I forget...
The real way to test is not from vent temps, but by measuring temp differential between inlet and outlet temps at evaporator lines. But another good way to test efficiency is at center vent temp, on max ac setting, recirc, all doors open
System running about 10 min. You'll want to see no less...
The MAF being wet is a good possibility, but also, if water did get into the cylinders, from sitting there's the possibility of the water seeping past the rings and getting in the oil also
Pull the spark plugs out and use a vacuum sucker to suck out. Or crank it over with the spark plugs out. But if possible sucking it out would be the preferred method.
