Looking to get some information on the big block chevy valve springs.

I currently have them installed and have been running them for about 4 years now but upgraded to a large turbo. Since its bigger I'll need to Rev a little higher since full boost comes on later.

Having a hard time finding some information about how high I can raise the Rev limit safely with those springs? I've heard 7300-7500~ from a friend but would like to hear some input about this. Thanks

Yeah guys i know that. Im not the one who wrote about not having overflow tank. I know physics and water expansion when hotter and all that....

Anyway - now im having 1.1bar radiator cap with temp gauge in it. i get max of 110C and its not leaking anymore.
110C is very hot I get a sweat on if my car gets anywhere near 100C

might be due to electric fans. i was using original Mitsubishi eclipse fans that do 1400CFM each and one of them stopped working. might be that and i know that 1400CFM is not enough. should be atleast 2000 to cool down 6 cylinder engine.
and i might get new radiator as well.

Does anyone know the length I need to have my driveshaft made to mate up to my stock lsd and to a short shaft th350?
I have my r154 and my new th350 so I can measure the difference. I was just curious if anyone else had a number so I could compare them. Thanks.

Is this front main seal seated properly? I cant seem to get it to go in any further though there's space behind it.

anyone know the bolt and or hole size in the hatch for an 88 wing?

how about the hole size for the rear wiper?

Recently got access to a lathe so I wanted to see if I could make some plugs for the holes.

Someone was making a rear wiper delete kit (I bought one... No idea where I set it...)

If nobody replies, I can look. I also have a 88 rear wing in my garage somewhere (same note as above)

I have a question about the stock water temperature gauge in 89+ Supras.

I have read in many threads that the needle is meant to sit near the middle of the gauge for a wide temp range.

Mine tends to sit at about where an hour hand would be on a clock for 3:20 to 3:40, but I have noticed that if I come to a stop, turn the car off, and then turn then engine right back on the gauge will read at around 4:00 until I do some spirited driving.

Just curious if others see this happening, and if it is something I should look into. Or is this just another facet of the "intentional sluggishness" Toyota has built into the gauge.

Thanks!

Assuming this is a rhd car? Generally when you turn a car off after its up to operating temp, the coolant temperature will climb a little bit right away. So if you start the car back up then drive it around, it will cycle the coolant bring it back down to operating temperature.

If you're concerned about the exact temperature you could install an aftermarket gauges

Left hand drive, though I should have specified that the pivot of the gauge needle would be fixed at 9 o'clock. Thanks for calling that out!

I am seeing the opposite of what you mentioned, which would be the expected behavior to me.
(Basically, drive car until gauge is at the usual peak, just below center, pull over and turn car off so that gauge "resets" to zero and then turn car right back with almost no delay, note that gauge now reads a fair bit cooler.)

That is why I was curious if this was just part of that gauge's slow reading. I am not worried about my temps, though a hidden digital gauge would be so nice. Or a factory gauge without the "sluggishness" :)

Jokes on me, for some reason I was thinking the needle was facing the other direction. It's been months since I've been in mine unfortunately..

As far as doing the opposite of what I said, I'm clue less.. I guess it's better than being hot!

If it has the speed sensor on the tail housing. the speed sensor should be on the left hand side and has (IIRC) a 4 wire connector on it. It will be separate from the 2 wire reverse light switch.

So I ordered a reman power steering pump from DM and I received a pump I'm not familiar with:

Reman'd on the left, stock 89 Turbo on the right:






The adjustment bracket holes are in different locations.

Does anyone know what this is from? What year?
Should I try to send it back? I don't have a bracket for this one and the woodruff key wont fit without shaving it.

I got my car running again after totaling my last shell. I noticed this wire when I bought it and it was running. It's getting hot enough to start melting the old electrical tape. It goes strait to the body harness. Is it even supposed to be connected to the positive? That's how it was set up before

This is probably more a silly question, but what is the meaning of NATO in the Cygnus X1 parts catalog?

I have found some threads here where people have guessed at the meaning, but I have always been curious if there is an accepted meaning. Thanks!

This one I can help you with. It refers to the Toyota range for NATO staff in Europe at the time.

Officially was called the NATO Military Sales Program.

Can someone let me know the stock ride height of the 89+ MK3 Supra? I have been searching all night and finding fun threads, but not the information.

I did use the TSRM to check chassis height and my front came in about a centimeter low while the rear was dead on. But I am not sure if that means much regarding the quality of the springs?

I am just trying to get a feel for how tired my 30 year old springs are. Thanks!
