i currently have a 02 0z rally which comes with the comin 4g94... the car still runs like a champ an i have no problem getting it to do what i want it to do... the down side is it has 257.xxx miles on it but still running strong. no clue really how much longer the motor has befor it dies but i keep up on the basics to keep it running. i know the weakest links in these motors are the pistons so my puestion is do i spent the money to rebuild what i have or find a diffrent motor an start a complete rebuild on it an if i do so what to get. id like a 64 but have only came acrost one in my searches and it was already built in someones car lls ... what should i do?

 

If you were to do a swap, I'd go with the 4g64. Should be able to get one from a salvage yard. But I'd only do a swap if you plan on making 300whp

 

Agreed
