    R-134A Retrofit Kit

    Jdub was referring to the fact that the 7M-GTE forum is for posting threads related to 7M-GTE specific topics. The A/C in the car is not a GTE specific topic and therefore does not belong in the forum you posted in. As far as conversions. Toyota offers all the parts to do a conversion, but if...

    Scan Tools! Informative Discussion

    What type of dealership are you working at? What types of vehicles will you normally be using it on? What year ranges? Just curious. Jeff

    1jz with 2jz water pump over heating

    The port on the side is the coolant feed for one of the stock turbos. If you aren't running a water cooled turbo, or you have it fed from another spot, it should be blocked off. There is nothing special about the 2JZ water pump being used on the 1JZ. In fact the 1JZ-GTE in the Soarer uses the...

    Changing Camshafts

    Toyota sells shims in 0.05mm (Approximately 0.002in) increments. Even if you aren't replacing the cams, and just putting the original ones back in, check and adjust the valve clearance. There is a reason you are supposed to check and adjust it periodically. Jeff

    LSD Rebuild?

    Interesting side note: depending on when your MK3 was made, it may have different preload and clutch types. Starting in April, 1990 the preload spring was reduced from 550lbs to 176lbs, and the number, type and thickness of the clutch plates and washers changed as well. There is a TSB regarding...

    LSD Rebuild?

    Toyota does not sell a rebuild kit, you'd need to order all the parts separately. Jeff

    steering column covers different between years?

    My only guess is the lock release solenoid on the ignition lock to not allow key removal while the automatic shift selector is not in the "P" position. Jeff

    Which Spark plug?

    Toyota switched from using the JIS to the ISO plugs at the end of the 80's in most new models or engine updates. The plugs are similar and have the same reach, but the height is different. Like was said, the 7M uses JIS (Denso "Q"), the 1JZ and 2JZ use ISO (Denso "K"). Interesting note for...

    Rebalancing Internals?

    That thread really does not apply to this situation. Yes the engine is internally balanced. Changing the transmission doesn't mean anything for balancing, however if you are changing any internals, definitely get the rotating assembly rebalanced. Jeff

    JDM tow hook

    I see it listed in both the European and Japanese cars (wide body only for Japan, not listed as applicable to narrow body), though I know most cars in Japan didn't come with it, as I have seen most come with the same style as USA (like Martin described). I don't know if I've ever seen one from...

    steering column covers different between years?

    There are basically 3 different fitments: 1. Without airbag (all pre-89 and 89+ w/manual transmission) 2. Without airbag (89+ w/automatic transmission) 3. With airbag Make sure you find one that matches. Jeff

    1j driveshaft difference

    Not country related. All those numbers are from the Japanese A70 catalog. The Japanese MA70 used the same parts as our MA70. Next time I'm under a real JZA70, I'll measure one. I should be able to get under a TT-R in the next week or so... though may not UNDER it... we'll see. Not sure why it...

    oil squirters in an NA

    He never said anything about using squirters in an N/A, though there are tons of N/A engines out there than use squirters, many Toyotas as well. It just depends what you're setting it up to do. Jeff

    Compression on 5 and 6 way high

    Really the most important part is the difference between cylinders. I'd say it sounds like you have 4 low, not 2 high. Jeff

    How did you slide a W58 shaft in? They have different splines on the front yoke? Jeff

    1j driveshaft difference

    Actually they were not all changed, but non-serviceable type were introduced. They were called M-Joint and V-Joint. When I checked the part numbers I compared the same types. M-Joint type is the older style serviceable U-joint, V-Joint is the newer non-serviceable type. 37120-24140 - MA70...

    differential question

    All N/A's were 4.30:1. In Canada LSD was standard. In USA, LSD was optional and was also included in the Sport Package. Jeff
