Hey guys I have taken the plunge and purchased a zfr. What I'm wondering is, does anyone running an auto trans have a zfr?
Obviously tuning will be key but I'm curious how the performance is with that turbo on the auto.

 

67 or 71?

 

Nice congrats I'm hopping to join that club

 

67 until I can find a better trans solution this is where I'll stay. Hoping to figure out how to complete the 4t65 swap from the gm build book.

 

I would have gone 71 the boost doesn't hit as hard. I dont know the strengths of the auto but being a smoother turbo has helped me save my current trans

 

I purchased the zfr gently used so the price of the 71 was just not in the cards. I know of a couple people running bigger turbos with power near the 400s who've had no problems and I've seem others that have lasted 40k on stock power. I run a secondary trans cooler and religiously changel my trans fluid so well see what it can take here in the coming weeks.

 

Hopefully you don't join the broken trans club.

 

I'm a 2 time member but it's been good on the 71 so far
