^It's not an issue of how long it will run. There is much more needed for a 1jz swap than an engine and transmission. So far I'm at about $4,300 total investment in my swap...I'm hoping to come in under $5,000. This is the reason why everybody doesn't do the 1jz swap...for that amount of cash you can pretty much build a 7m that is well built and nearly bulletproof.
