Looking for a new motor for my 04 tacoma 2.7

Just spent 1700 on my taco to have a new head put on it cause it cracked, the mechanic said the antifreeze was bad and let the head freeze and bust. Now it's still mixing anti freeze in the oil so the block is also cracked. I've decided im just going to put another motor in it instead of trying to find a bottom end and have some one put them together for me. I've found some decent priced ones from about 1800 rebuilt to 2200 new from japanengines. I was also wondering how hard it would be to put a supra 1jztt 2.5l twinn turbo in it I can get one of those for about 1300.

 

I just put a rebuilt motor in my 96 taco from KarKing it's like a brand new one. It was 1950 after shipping.

 

I ordered a brand new one for 2100 from apr so hopefully its a good motor.
