Little or No turbo lag from a single set-up....on my 390ci....Possible...?
I know theres a lot of factors that go into building the perfect combo.......but what turbo size is best for the 390ci....through a 4L80E. Id like to make 800/900 RWHP.
My friend just built a single turbo T6 complete turbo kit that retains factory A/C and factory sway bar........and he said he will build me one too.....so I'm thinking of going single instead of Modular Turbo TT kit.....
But its a 100% street car......Id like to have a smooth acceleration from down low all the way up to top speed highway pulls to 160mph.......
I really don't want that big slam of boost coming in at a certain rpm....
Is it possible.....?

76mm will choke that motor up top. With My pt7675 on my 5.7 I have no lag. I think something a little bigger and a correct spec'ed cam would do you wonders I'd get together with a vendor and have them put a combo together that would work well.

Same turbo here on a 383 and it has almost zero lag and runs like a freight train up top. That's where why I would look. The almost no lag full boost pull were astounding to me. Made mid 600s on 9 psi. About to go meth and biggeer pumps and up it to 18 psi. Can not wait!

You are talking apples and oranges. Your turbo has a 75mm turbine vs the 92 or whatever mm of the s476 that I'm talking about. If I'm not mistaken,there are smaller turbine wheels available for the S400 also.
