This thread is from 2013...so...crazy how time flies...
This engine is even better then I hoped it was then.
Best bet is running a complete drivetrain from a 4x4....this presents some issues due to how low the late t cases sit in regards to ideal.
If your not using a power adder then consider this.
..the 4cyl Ecoboost with a sbf adapter is the best solution for my application. Because I have all of those parts. I have r2 and r1 options ...the power is better...but not enough to be the factor. Much easier to adapt though.
The r2....or whatever...435...zf.... t 19, ect allows easy use of doublers and np205.
There are a few companies with different variations ford gm and toy and dub using bells and or plates that can retain stock starter/flexplate with the cyclones. Most are expensive...
.but the 6r80 is a beast and very cheap.
