Thanks for the reference. If it needs more than a gasket, I'll probably take it there.

Doesn't the engine call for 5w20?? or 5w30? I guess in the warmer climate you are ok with 10W40 but it sounds a little heavy. Yeah watch the WOT stuff because without proper cooling you will generate hot spots in the head that can cause more damage.

The engine calls for 5w30... people using 10w30 need to realize that 10 is just the winter weight (hence the w) or cold weight of the oil... so when the oil is cold, it acts as a 10 weight would. When it gets hot, it acts as a 30 weight would. So once your engine is warm, the 10 doesn't do anything for you as far as "thicker film" or in helping prevent blow-by... maybe a 5w40 would be a better choice but I am sticking with 5w30 when I boost... maybe after many miles I will change to a thicker viscosity... just my 2 cents


Go to the dealer immediately though! The earlier you catch it the less damage will be done. Pinging is as you know is a bad thing...

Yeah I figured being in Cali you were not dealing with too much cold temps. I have 5w50 in my xB . . . wait for it . . . wait for it . . . yeah 5w50 from Synlube - talk about your high temperature protection and it still pours like really thin oil - not water.

Yeah it's not that cold around here so I run either 5w40 or 10w40. The engine brainiac in this thread recommends thicker oil than the 5w30 that Toy recommeds, and he seems to know his ish, so that's what I've been using.

Good reading, if you haven't read it already. Grab a cup of Joe before you start reading because it's a Looooooong thread.

Turbo or Supercharge the tC motor is not ready for it You need to rebuilt you motor. Good luck

Hey ScottTx13 that is an interesting post and as I had thought there is a potential problem with the presure buildup in teh crank from teh vent connected to teh intake and that may actually be blowing oil vapors into the intake when you shift causing the puff of flame to come out the tail pipe since the oil probably doesn't burn too well in the engine with the injectors shut off when your foot is off the gas it vents out the tail pipe and ignites in the cat.

Sounds like you guys need to look into a eCycle electric powered supercharger and then you can run NA most of the time and then kick in the variable electric boost as you want it without all the bearing problems and belt problems.

ScottTc13

LOL..... ok. So out of curiousity, how much does one of those electric superchargers cost, installed. I'm guessing that you would need more batteries than one 12v and some sort of electronic motor controller to regulate the speed of the supercharger,

Probably about 1200 for the brushless electric motor which can run on 12 volts at about 400 amps max and I am not sure about the blower since they use a standard one not made by them. The controller is maybe anywhere from a few hundred to almost a thousand depending if you get your own or one of theirs. Then you need some plumbing etc but it sure beats having a belt spinning all the time and the loss in power wasted running the blower is taken from the battery which you recharge later as you are slowing down so you can get a higher peak HP out of the motor.

Sure looks cool and I saw the actual supercharger in person and it was pretty neat.

Hey if you get a decent battery setup and their motor and controller you can make your car into a ISA hybrid.

ScottTc13

^^ Definitely an interesting concept, but I'm sure it would cost upwards of a few grand all said n done. I got my TuRD SC for 1500, while not perfect it was a good deal. 15psi is definetly enough boost. But it does specify that the voltage needed is 14 to 54vdc.
