I have decided I want to move to a better turbo. presently I have a 88mm gt45. Nothing wrong with the turbo but Im ready to move on so im not worrying constantly about a turbo failure. I know they are used all over successfully but my luck isn't good with it should work. I have a lsx 376 b15 with a tick stage two cam, holley high ram, 2800 stall converter, built 6l80e and 3.27 rear gears in a 5th gen Camaro. Im looking to be around 800 to 850 ish with room to grow later maybe. I fabbed my own turbo kit cause I can and damn everything 5th gen costs double. Contrary to popular belief you can fit a 4 inch down pipe between the fenderwell and the engine on a 5th gen. Car is 90 percent street driven. I was planning on doing a gt88 garret from forced inductions but when I called to inquire about it I was told to go s480. I figure they know better then me so Im going s480. they recommended the s480 billet 96mm turbine. Im gonna stay with the standard cover due to it being dead on with my cold side I have now. I know Im gonna need to change the t4i flange to t4 no problem. my first question is should I go billet 480 or stay cast since Im staying standard cover. What is the perk to going billet if Im not going to push this turbo to its limits. will it spool better. Im not cheap but the price difference is considerable and I don't wanna spend money just to say its billet. second question what ar should I get the t4 in. I was thinking the 1.10 but Im really just guessing. opinions please.

I've read the billet wheel was worth some power and a decrease in spool time. No empirical knowledge on my end though.

I have a billet S480 T4 1.25 96mm turbine and race cover unit in my car. This replaced a 2.3 Whipple...I dont think I will miss the Whipple.

S480 is 80mm. You're going down from 88mm to 80mm!

I went 9.0 last season with more left in it on a cast S480 T6 1.32 AR from FI
Motor was a SBE 6.0

Putting it on another car this season and hope to get it into the 8s.

yes I'm actually moving from an 88 to an 80 but the turbine side of the gt45 is only 77mm which I think is causing me to have a huge torque number down low and power falling off up top. After alot of research I have seen a trend where cars with too small a turbine do what mine is doing so I'm actually moving to a larger turbine plus I really don't need an 88 to make 800whp. I'm not sure I even need the 80 really but want some room to grow later. I'm just wanting to know in my situation if the billet is worth it or not. I just don't wanna call and bother forced inductions again for something I probably should have ask in the first place.

I see no issue in calling them...You're a legit customer who wants to spend money. Also, buyer's remorse sucks *****, especially on a high dollar item.

If you don't want to call them, go on Facebook and shoot them a message.

A good cover with the cast wheel would be a better use of your money if you're looking for some room to make power. We have made over 1300whp on a smallblock with the cast wheel in our race cover.

The 80 in a remachined 75 cover (standard cover) will run out well before the cast wheel. Going billet won't help in that department.

The GT45 88mm turbo he has now is not on the same level as the S480 cast wheel unit, let alone a billet wheel unit.

That GT45 88 doesn't move the airflow that a S480 or ETR-HO S480 does.

Back to back tests.... Cast 80 versus Billet 80 with race covers....

Cast 80... 1042 at 24 psi with the gate pinned shut
billet 80... 1289 At 29 psi with the gate pinned shut.

The billet wheel in the standard cover.... wont be as good as if it was in a race cover... but if you only have the 400 bucks to do one or the other.... do the wheel first.

I have a s480 with race cover an cast wheel, how much is to upgrade to a billet wheel?

LJMSJohn

From me... 450

tblentrprz

Good info. Looks like whp. Any chance you have logs of rpm, hp, tq, and boost?

Jax326

Opposite question. I have a standard cover/ billet wheel from Midwest, how much to upgrade and can I swap to a V2? Will it fit or is there machining or anything involved?

I went with the S480 billet wheel and standard cover, ordered it yesterday from Forced Inductions. They told me the billet wheel definitely spools faster than the cast.

I went ahead and ordered the billet wheel standard cover s480 96mm turbine with the 1.25 AR t4. It will bolt directly to my kit with a t4i to t4 flange change. Maybe even just elongate some bolt holes I haven't checked yet. I will move up to the race cover later. Thanks for all the replies.

I did the same on my new setup. Ordered the billet wheel s480 with standard cover. 96mm 1.32ar t6. The race cover is something u can easily swap out. The billet wheel needs to be installed and balnaced etc. So i figured do the wheel and ill swap the cover myself later. Win win!☺

LJMSJohn

considering your turbo came from Midwest... it would have to be sent it in order for the cover to be machined to match the wheel... Obviously Jose only has cnc programs for the covers that match his wheels....

the V2 race cover would be a 500 dollar upgrade. and there would probably be some extra money tied up in machine time because he would have to build a program to match that specific wheel.... Depending on how much that is.... might be cheaper to switch the wheels out depending.

i was just going to post
i believe its 200-250whp flat out
plus better response
