Hello, and sorry if this ended being published in the wrong forums

I'm been interested in buying a project car for a while, and I've seen some powerful twin turbo setups for 4th gen F bodies.

So, I want to ask: What are the biggest turbos I can install in a 4 Gen F body V8 LSx swap, without needing to cut the chassis or removing the radiator from its original place?
Foto I found in reddit for illustrative purposes

 

Ironic. I just had a good conversation with the guys at Precision turbo at LSfest for my sons car I'm building into a twin setup.
64/66 is what they recommend. Even for his build which is a Dart 427.
Give them a call. Granted their turbos are pricey, but they will give you good advice even if you don't buy theirs.

 

There's a reason Precision turbo stuff is pricey, that **** works!! The numbers I've seen from the 4 cylinder stuff on a single turbo is crazy. Then it gets crazier with the 8 cylinder builds

 

This is likely irrelevant, but my new build in the chevelle will be running a set of twin 64/66 TurboSmart turbos on a 403ci iron stroker w/ls3 heads. Hoping to make over 750rwhp on pump 93 <15psi thru an 8spd/ford 9".
