7AGE hybrid
1UZFE
2JZGE
K24A1
I am leaning more towards the 7AGE hybrid because 16V large port heads are fairly easy to find and 7AGE engines are in junk yards everywhere I look. Therefor, ease of finding parts and budget come to mind. BUT, reliability is my main concern as I have sifted through many 7AGE build threads and found people arguing about the strength of the 7AFE bottom end when turbo or high rpm.
The 1UZFE comes next because it is also easy to source engines for and is reliable, but the swap kit and transmission parts are NOT budget friendly. It seems like the most performance oriented though being an all aluminum and down right sexy Toyota V8

The 2JZGE only comes to mind because of it's reliability, ease of finding parts, and, while N/A, not that expensive. It is extremely heavy, but later on down the road when turbo, I can move some weight around to make it worth while.
Though I would like to keep it all in the family and run only Toyota parts, the K24A1 Honda engine is sounding better and better. All aluminum, rev it all day, easy to find these motors(2002+ CRV, ACCORD, etc.) and reliable. Much like the 1UZFE though, the drivetrain is the most expensive and time consuming part. I've seen Will Parsons progress with his F20C swap.
I would love to hear everyone's opinions, information, wisdom and excitement! haha
Thanks,
Andrew
