    Street tuning for 7M engine break-in with safc2 questions...

    I would reset the ECU if your setup changed and start from scratch on the SAFC. However to answer your question, yes the ECU will adjust to the new settings but keep in mind with an SAFC anything over a certain percentage will make the ECU think something is wrong and start correcting the map on...

    Looking for coilovers

    Im running a set of Tein Flex Z on my Supra. I am satisfied with them coming from my old Tokico Illumina II and H&R spring setup. They passed the old man test (having my 72 year old father ride in the car with me). I am satisfied with the 16 way dampening.

    Fuel pressure issues. Help.

    If youre not maintaining pressure at the rail, I believe that points to your regulator. You answered your question, when you pinched or restricted the return line a bit to success.

    Hks intercooler kit for 1987-1992 supra

    The US Market kit of the Japanese Market Kit? Either one assuming there is a market for HKS parts for this car, id say $1000. However with the influx of Chinese intercoolers, most people would rather save $700 and get one of those kits.

    Wheel Fitment & Question Thread

    My work wheels are 17x8 +35 and they do not look sunken at all. I also ran 275 on a wheel with +50 with no rubbing on the rear. Same with the Work wheels being +35 in the rear. On the old Kei Office wheels I used, I could've run a 275 with zero issues, I'm curious to why you had issues?

    Stock Mk-4 Supras

    You have to look at this differently. If you're buying the car for driving enjoyment, then an N/A or a TT car will suffice. Both are exciting, one is quicker than the other. So for cruising and weekend enjoyment, a naturally aspirated Supra is not a bad choice, maintenance is easier, and overall...

    MKIV Supra made after 1998

    Supra production continued until 2002. I am not aware of any LHD +98 made, although I know for sure you can find a RHD +98 model. They came in N/A and Twin Turbo variants. Options for the cars varied on model. SZ, SZ-R, RZ, RZ-S models. The 25yr import rule applies to any car manufactured...

    Supra stories from Japan

    Same thing with the other chassis codes. You'll never hear them say nana-jyu. Look at the R32, 33, 34 chassis code, they say san-ni. or san-san. So it seems normal.

    DIY: R-12 to R-134a Conversion (How To)

    I'm glad to hear this is still helping owners. The expansion valve for the JDM cars are the same as the Pre89 bulb style expansion valves. I don't think they ever went over to the block style TXV overseas. Yeah haha I've had to remove the compressor from a few 1JZ cars before and its not as...

    Anyone have mapecu tunes?

    Kind of hard to use someone elses tune, your VE tables wont be 1:1 to another car. Why not just set up the table on your own?

    Recommendations please

    Id go with a sound performance upgrade myself as well. I have to second plaaya69 regarding piggybacks. To give you the short story, if you use one and you pull fuel to lean out the mixture you inadvertantly advance the timing, if you add fuel you retard timing. What this means is you run the...

    LED Headlamp Install

    2000 grit, 2500 grit, and 3000 grit sandpaper. Wet sand the lense, I used Meguiars 105 and 205 to buff out the sanding marks. Only sand if you have oxidation on the lense. Otherwise go straight to polish.

    You can polish the old plastic cover and sell if you really want to, or keep it for a back up.

    Air Duster Cans as R-12 Refrigerant Alternative???

    Figgie is right. Every Supra ive converted, in fact every R12 car ive converted performed just as well sometimes better than the original system. Ive dealt with badly converted cars, most of that dealt with oil capacity, refrigerant capacity, air in the system, or faulty components. Also by the...

    Going back with sawblades

    a 5 or 7mm spacer. 225s are pretty much your only option. 245s and 255s start to balloon on the stock wheels.
