TEMS upgrade?

You might also like to check out supramania.com and supraforums.com
Both are excellent sources of information for Supras, but as yours is a MKIII, I would highly recommend supramania as most of the members on there have MKIII's.

If you haven't replaced the HG yet, that could be something you'd like to look into. The OEM HG is known to blow because Toyota, from the factory, only torqued the head bolts to around 56 ft/lbs, where they should have been torqued to around 72 ft/lbs. Most people go with Stone HG or a metal HG, with ARP head studs. As for your suspension, if you would like to keep the option to use your TEMS, the Tokico Illumina shocks are the only aftermarket shocks that are TEMS compatible.

I'm just relaying to you what I've read and how I understand it, I suggest searching supramania for sure.

I hope this has helped at least a little bit.

Thanks for your response, and the suggestions. I know more about restoring old tractors than my Supra, and it's time I connected with folks to give me some guidance. I'll check out those other sites you mentioned as well.

I really don't care about the variable shocks, as I never change the setting. Can you, or anyone else, recommend some "regular" replacements that are in line with the firmness of the "sport" setting?

Also, I've never changed the timing belt (135K miles so far). Is that something I should consider soon?

Thanks for the insight on the head gasket. Again good new information!

I honestly am not sure about the timing belt.
On Supramania, there is a section titled "subject matter experts", and suspension is covered in there. "Wiisass" is the one who should be able to give you the information that you're looking for.
