My piston is broken

Rhonron,

I am sorry to hear this and on a supra, That is a major bummer. What are you looking at doing from here. do you want a basic set of instructions to rebuild the motor yourself? are you going to purchase a new, reconditioned or junkyard motor to replace the motor?

Also it is really helpful if you could give me exact year, model and motor to help me recommend the correct parts.

I kind of need to know what route you want to go and what your skill level and tool kit size is and what budget you have to move forward. I won't say you can't do it on your own in your garage as many years ago i did it on my first car when i threw a rod through my oil pan from pretending i was a race car driver. lol I was only 16 but had resources in the way of my father and grandfather for knowledge.

Basically what i am saying here is better make sure your bus pass is good as driving it for awhile is not an option.

in any event you are looking at between $3500 and $4000 to get a replacement block and up.

Replacement block 2 JZ replacement ( I am guessing here )

If you have any questions feel free to ask. I don't mind answering if I can, i have at least 3 decades of car repair professional as well as private under my belt.

Let me know, sorry bro.

Monte
