Default Are there any factory turbo's big enough for a V8 ?
Im wanting to do a DIY turbo setup. I cant seem to find any turbo's off factory vehicles that are really big enough for a modified V8. Are there any that anyone knows of ? I would REALLY prefer a single. I would consider a twin setup if I have to though. Its for a 331, sbf.

another option would be a larger t70 turbo with a t4 inlet.

the t70 is a popular option in the diy mustang circles, set of bbk shorties flipped over with a custom merge pipe

if u go that route make sure u get a full t4 t70 thats atleast a ptrim

Its a Dart block. I was going with a GT 4788. Just looking to save money and get performance close to that.

ur only option would be like a set of twin 60-1's/t61 if u wanted to go twins.
but honestly id go with a single bw s475 which can be bought for just under 600 bucks brand new.that turbo has pushed many small blocks well into the 8's

this thing carbed or fuel injected

I had looked at that one, and the 480. One guy told me he built one with the same engine as mine. same heads intake, ect, and it went 8.20's with the 47-88. I'm just looking for low 9's. 475 good for that ? The cars only 2900lbs with me in it.
