I saw something confusing over at supra forums http://www.supraforums.com/showthread.php?s=&threadid=29466 and thought I'd ask about it here, because maybe Chris Eng will answer it :wink: .

Toyota4555

84: In 1984 it gets tricky, all automatic and L-type supras came rated with a 150 h.p. and all 5-speed p-types had 160 h.p. Now this was the first year where the front turn signals were wrapped around. It also got a new steering wheel, cruise control was moved to a stalk on the steering column, and a more aggressive front air dam was installed. Now the gear ratios changed as well. 5-speeds got 4.30 gears while automatics recieved 4.10 gears. Also the mk2 recieved a hatch sticker that went all the way acroos it that said "SUPRA"

I've got an '84 P-Type with the 4spd auto, does this mean I have the 150hp engine? That's what Toyota4555 says, but I've never heard of this engine differece before. Has anyone got more information on this? Would it be worth my time changing whatever's different between the engines for the 10hp gain?

Problem 2: My hatch sticker is just a small thing in corner, not the big "SUPRA" across the whole thing. When I bought the car the dealer mentioned some minor accidents, so the hatch might have been replaced.

(Did a search and nothing like this came up, so I hope I'm not making a repeat thread)

You the man, man :thumbup:

I'm pretty sure the accidents the dealer mentioned were to do with the front of the car, as the bumper is kind of bent and the paint is flakey.
My VIN conferms the car is an '84, but I haven't remembered to get the firewall code yet so I guess it could be american.

Didn't know the digi dash was CDN only, cool.
Anyway, that's what I've got and if there's still any doubt the firewall code says it's Kanadian :lol:
Here's the code if anything else in there might be helpfull/confusing:
MA61L-BLPQFK

F: 7.5"
29: 4.10 gear ratio
3: 2 pinions/ with LSD
Just looked it up myself, I have no clue what any of that means though.

Why is YS84 discribed as "84 Performance" on the decoder page?

Right here:

There's a sticky thread on it in 'General tech questions'
Here's your stats: (think this still applies to XX's)
Rear gear diameter: 7.5"
Final drive ratio: 4.30
Pinions/LSD: 2 pinions/ no LSD

Also, thanks again CJ, I aspire to your level of expertise.

I realize theres a whole other can of worms going on here, but back to my original question. What is the actual difference between L and P-Type engines and would it be worth the time/effort to upgrade for the extra 10hp?

I finally found out what the difference is, in case anyone besides me didn't know:

Which tranny???

I now have confirmation that the Canadian 84 motors are setup the same way as the US motors.. So.....

If you have a 5-speed, then you have the 160 hp motor, which should be the 9.2 compression motor.

If you have a Automatic, then you have the 150hp motor, which should be the 8.8 compression motor.

Now if your motor has been swapped in the past, or if you have gone 6M, then things will be slightly different (well, we know that 6M's are 9.2 compression).

This is from Opron's 5mGTE thread in the 5/6/7mgte disscussion area.
Thanks Chris!
