Hey All,

What should the timing of the Engine be? currently i think i am running at 16Deg TDC but it seems to be running rough with LRP...

Cheers.

is it not on the sticker on the underside of the bonnet? i cant remember if it is mayb not
haynes manual says:
1979-1980....12degrees BTDC at 800rpm with vacuum lines connected
1981....8degrees BTDC at 800rpm with teh vacuum lines disconnected and plugged
1982.....8degrees BTDC at 650rpm with teh vacuum lines disconnected and plugged
1983-1986.....10degrees BTDC at 650rpm
i think the US 1981 supra had the 5me so i guess its 8degrees then

Oh yeah... I can't rely on the Haynes Manual with the American MA6x Supras because they are fitted with a 5M-GE.

the older US supras came with a 5me (79-81)
just had a look, the sticker says

16degrees BTDC at max 950rpm

that is for 98RON fuel - good luck running 16deg on LRP Laughing Laughing

try ~8deg with LRP and an old engine...

Cheers Ed_MA61, I'll detune the engine when i get up this morning/afternoon Embarassed, and retune it when I get a tank of 98RON petrol next.

Cheers.

even 14deg is still too much for the crappy LRP or even regular ULP. you could probably get away with 14deg using premium 94-95RON, but for 91RON ULP or LRP, i HIGHLY suggest dropping timing to under 10deg
