i have a 88 supra turbo wich i just bought for $800. No surpize the head gasket was gone. I have taken the head off and found that one of the camshaft jornals (exaust #2)and the head and cap surfaces were scored. All the rest were in good shape for the 148,000 miles on them. I can get new cams I found a 2 places that makes custom grind cams out of yours but can not fix journals, Toyota wants $419.00 for each cam I will not pay that for stock profile. Even if i were to get new ones the head and cap is scored. Does anybody have this problem or know how to fix it. I have also found a new head for $530 but If i can fix mine i would like to. Do you think the new head would be best?

For the prices of these you can find them MUCH cheaper. You can get a whole motor shipped for $900, and on SupraForums.com I guarentee it wouldn't be hard to find stock Cams or a head. Only problem would be shipping on a Head. Warpage, damage, and weight would be a serious pain.

As for stock cams, I've even got a pair of stock cams laying around.

jeeves thanks for the reply. I have found cams for $149.00 each and a whole head for $530 with valves and cams etc A complete head brand new no warpage cracks and no carbon. The cams i found were from topline but i do not know if they are stock profile. Does anybody know the answer to this?
The previous owner said the bottom end was rebuilt but i do not know if he was full of it. Today i looked at the cylinders and i could easily see the cross hatch now the moter has 148,000 on it so i think the cross hatch would have worn out. I am not familler with toyotas but i know that millage on most cars and the cylinders are shinny and there is minimal cross hatch. If anyone can enliten me on these well enginerd toyots please do so.

In my 120+mile 7M you could still see crosshatching..
