My buddy is putting a 5.3 or a 6.0 in his Fox and he already has an S480 because he'd planned on a 6.0 initially. Now a 5.3 has come up as an option and we're worried about spool time while street driving. Will the 43 fewer cubic inches cause this turbo to spool noticeably slower on the street?
He isn't going to all-out drag race this car at the track very much, he just wants to beat it up on the street and wants it to turn corners and handle well rather than be a top end car.

It's a matter of $350 difference and a little more knowledge about the 5.3 as it runs in a truck right now and the 6.0 is in pieces.

what turbine? If it's the 83mm turbine it wouldn't be terrible, but that is why more compressor wheel than he'll be able to use. Also what trans?

Like NoorJ said, turbine info would be helpful. What kind of power is he looking for? That combined with displacement is the single largest factor in determining turbo size.

I got a 88/96? I believe its going on either my 347 or a 408

Looks like its a 1.15 A/R and an 80mm and he's running a 4l80e with, at this point, a stock converter.

I'm just concerned about the low end spool time.

I have cast s480 on my 408 and it lags from a stop and trying to build boost off the line. Good from a roll with my converter. If i had to do it over again I would of went with the 1.10 and i believe its the 92mm wheel... If i was doing a stock 5.3 / 6.0 id look into the s475 maybe with some billet wheel if the budget is there.

I just got a T4 Billet S480 1.25 AR for my 6.0 4l80e combo with a Yank 3400 and 3.50 gears.

Hope mine is not laggy...

cam, gearing, tire size, motor size, header design and perspective are all at play.

understand a S480 with a big turbine is certainly not a high response road race style turbo haha

cptinjak

Still haven't heard a horsepower goal. That is one of the most crucial factors to determine if you can go smaller to improve spool, and how much smaller you can go.

That's my fear. He wants to be able to put the power into a corner and not wait on it I think.

Stock 5.3 or stock 6.0. Stock cam. Not sure on the gears. We're either going to try to use his 351 turbo headers or stock manifolds. Maybe a 2" hot side.

I believe he's looking at around 600 to 800 crank, which seems broad, but he really doesn't have a frame of reference for that much power... he just wants a lot of power and wants to be able to use it on the street, not only at a drag strip.


Should he consider just selling the s480, going with the 5.3 and buying a different turbo that will accomplish this goal more efficiently?

He originally bought the s480 for a 408 ford 351 stroker, but has since decided on an LS...

cptinjak

Yea 600 and 800 are very different things. Did you ever find out what turbine the 480 has?

I have a 6.0 with the s475 83 turbine, 1.10 and I think its spools a little slow as is. Couldnt imagine anything bigger turbo-wise for a reponsive street motor.

Sub'd for the outcome.

NoorJ

I would sell it for a t4 s472/83mm or s468/83mm if he goes with with a 5.3

Se worry for me. I any the future 4.8 or 5.3 liter build wth a s475 to be able to get down the track with a nice 60 foot and still crank up on the big end. Don't want a turd 6" foot and talk a out my "high MPH":

im not a precision fan but their 7675 style turbos light so quick and make amazing power

in a 6spd car i did 613whp on 12psi and 12deg of timing and it Lit FAST like boost at 2300 wastegate open before 3k

Matt any experience with the TC76/78? Seems like they are a great STREET turbo and they spool fast and package nice. However, some folks here made really great power with them despite the turbine.
