1JZ Engine Swap into '89 Supra

[kyosukerob]

Hi, new to the forums, though I've been a fan of Supras for a while now. I've been looking for an affordable and quality Supra for months (both seem to be impossible to achieve) though I may have been able to find a good deal now. I've come across a 89 Supra with a 7MGE for $700 with a blown head gasket and a 1JZGTE engine/ECU/transmission/twin turbo for $850.
Now, I'm wondering how much a swap costs to have done and what I'd have to do to make sure the Supra could handle the power from the engine without getting torn up. I know swaps cost a lot (hopefully selling the stock engine/transmission would help a little) so I may not have the cash left over to fortify my car from damage caused by its own engine. I recently considered a MR2 and found the non-turbos need a good bit of upgrading to handle a turbo engine.

Thanks in advance for your help, if I get the car I'll be talking to everyone here much more often.
