    How to find out if a sensor is bad?

    Why don't you try reading what the TRSM has to say about a specific sensor ;) Just a thought...a real novel idea actually.

    cooling question

    Jose speaks the truth...I have the dual FAL fans on a dual core radiator. Works fine for stop/go traffic and on the highway where the air flow is good. If you do anything else with the car, you will have coolant temp issues. I'm going with the stock fan/clutch and shroud.

    Has anyone does an Air-to-water intercooler setup?

    IJ ran an air-water IC...he switched to air-air though ;)

    What is the valve cover coating?

    The problem with powder coat is the heat...I've seen powder coating dull and even change color shade...it's going to depend on the material used and the skill of the person applying it. Heat resistant paint is about as good, if you do it right. A polish with clear anodizing doesn't...

    Does this sound like a bad fuel pump?

    You were told wrong...Fp and +B have to be jumped (just like the TSRM says) for the pump to run with the motor off. Stop listening to your friends and RTFM. If you can't find the time to check for codes, there is no point in "guessing"...it's a complete waste of time.

    What is the valve cover coating?

    The valve covers are cast aluminum...you can polish or paint. Been done many times...I chrome ceramic coated mine. Got another set sitting right here ;) BTW - the search function is your friend.

    Does this sound like a bad fuel pump?

    The FP does not run unless the engine is cranked. Here's how to test if the pump is operating: http://www.cygnusx1.net/supra/Library/TSRM/MK3/manual.aspx?S=FI&P=71 The check engine light does not come on for all codes...here's how to check for stored codes...

    cooling question

    ^^^ Agreed ;) Running a motor without a fan in Phoenix AZ, in the summer is actually an incredibility dumb thing to do considering it was 110 deg F last week and it's going to stay that way for the next couple months. The coolant mix needs to be at least 50/50. I hope you have a...

    odd compression test q&a

    IJ nailed it...read, don't skim...the OP removed the Viton from the MHG. The reaction between copper spray and Viton is the problem...there is no problem if the Viton is removed (on a new or used MHG).

    Rod knock

    If you don't want to act that way, why dont you actually be smart and read the previous posts (like #19) :3d_frown:

    Oil Cooler yes or no?

    Zazzn - If that guy is like some I see around here, the PermaCool is better because he's using one ;) I bet he's not running a thermostat to the cooler either...bad move if I'm correct. Send me the link to the thread...I'd like some amusement today. The stacked plate coolers (like B&M) are...

    Crank choices...?

    7M...no doubt. Took me several weeks to find a good one. You can also look for a late model Cressida...the good think about one of these is it's likely led a fairly benign life ;)

    Automatic tranny mods

    IPT will modify your valve body...they make higher stall TQ's too ;) http://www.importperformancetrans.com/toyotaauto.shtml#main

    Never run Platinum plugs under boost?? Why?

    There's nothing intrinsically wrong with running platinum plugs...they will provide good service even in boosted applications. Platinum plugs are not as efficient as copper, but the harder platinum will resist erosion much better. Using the correct heat range and properly gapped, platinum...

    Oil Cooler yes or no?

    Perfect! Thank you ;) Yes you can replace the stock cooler on a 2J. You will have to connect the two coolant hoses together (replace with a single hose) and get a sandwich adapter if you want to keep the filter in the same location (assuming there is sufficient head room for the plate...

    Never run Platinum plugs under boost?? Why?

    Agreed...you can run platinum plugs with no problem. IMO, NGK coppers are better, but you'll have to change them more often.

    Oil Cooler yes or no?

    Can you guys provide me a link to the 2J lube system description and diagram? The answer I'm leaning to is "yes" tlo86 ;)

    Oil Cooler yes or no?

    Guys - according to his profile this is a 2J...iirc, the oil cooler circuit is different and uses a oil-to-coolant cooler. Still, a good oil-to-air cooler will be more efficient and a thermostat will help get the oil (and keep it) at ops temp better. I moved this to the Other Engine Tech...

    Did we lose any Members or Supras....[USA]

    Yes it does... OP - please pay attention where you post ;)

    Oil Cooler yes or no?

    That's interesting, I just got a PM from a Toronto guy about the exact same subject. ;) Same reply: B&M coolers are top-of-the-line IMO...there will be minimum (if any) pressure drop. If you're going high HP on this motor, I would use -10 lines and run the biggest B&M cooler you can fit...
