I have a 2000 Camaro with an 8.50 cert chassis, 9" rear, built Turbo 400 with higher 1st gear and high stall convertor, full suspension, etc. For motor I have an LS2 with LS3 heads. Want to build car for street and some track use running e85.
Started looking at the Huron Speed turbo kits and was originally thinking the T6 with something like an S480. Would some of the VS Racing race cover, etc. stuff be a step up from the S480? What do you recommend in the Borg S480 price range?
Also, looking at the HS twin turbo kit. Any suggestions for turbos with this kit? Any opinions on packaging, or which kit would be better, between the single and twin kits?
This will be my 1st turbo build. I am trying to keep costs somewhat under control without cutting corners. Hoping to build something reliable, that runs cool enough, and has good power capabilities.
Running the HS T6 kit on my 1999 Camaro with a forged LS1 and billet S484.
Spools up pretty quickly and the fitment is excellent, can't speak to the twin kit but I'm sure the fitment is excellent there as well.
For a big single, if you plan on pushing the LS2 then I'd look at the FIS 91/102 otherwise any billet wheeled 80-84mm wheel will work very well.
Had several people tell me that the S484 will max out around 1,200whp so plan accordingly.
The VS stuff is good but not on the same level as the FIS products.

I will take a look at those turbos. 1200whp capability sounds like plenty to me. Good to hear another person happy with the HS kit. Thanks.
Pic of install w/ the S484.
I've been very happy with the kit and its performance, spools up nicely on the brake and has excellent clearance around components.

That's a big boy in there. Looks like it fits well though. I have a manual rack and no anti-lock brakes so that should free up a little space. Are you running power steering?
I talked to FI today. They said "S491/102 T6 1.32A/R works very well with that setup." Any opinions?
I am a turbo rookie, but my thinking is I would rather have something that is a little soft on the bottom end and maintains low back pressure if turned up a little. Does that make sense?
That's an older picture but I've since switched to manual brakes and the car already had manual steering.
It's not as tight as it looks either, I can still get in down around the front of the engine and what not.
Jose at FI knows his stuff, hands down one of the best in the industry so I'd take what he says as gospel.
I've read from many with more experience than me that with a 96mm turbine wheel anything more than an 80mm compressor wheel size iirc will overrun the turbine faster, the 80mm is the best balance for maxing out the 96mm turbine and guys are doing that on fewer cubes than you.
With that I'd go to the bigger turbine if you can afford it, really it's a one and done because if you wring everything out from that 91 then you'll be getting into really, really expensive turbos or twins.
This turbo on my setup is definitely a little soft down low but I like that for street racing, makes it easier to control, I'm still seeing 10 lbs. at just under 4,000 rpm lightly foot braking it so it builds boost pretty quickly.

Thanks for the response. The one and done philosophy makes sense to me, instead of starting with a 7875, s480, etc.

That's literally what I did too, started with a 7875 combo and moved up from there.
7875's are great for street cars and guys have gone mid to low 9's with them but that's pushing them to their absolute limit.
If you wanna go faster than that and do so reliably, it's much easier to move to a T6 combo, if you outlined your goals to Jose at FIS and he recommended that turbo then that's what I'd go with.
As John mentioned, the smaller S400 units are identical so if you ran a smaller used unit in the meantime, you could easily upgrade later with no other changes.
I was last weeks old when I found out that a BW FIS 91/102 has the same exterior dimensions as my S485. That made me very happy.
Did Jose say what kind of power potential that turbo has?
I've been told the S484 is good for around 1,200whp so I'd be curious to know what the 91/102 can do.

When he recommended the S91/102 for my setup, I told him I wanted 1500hp crank capable without excessive back pressure. Not sure what the limit or WHP would be. I know I have seen equipped cars in the 7's.
Figure for a solid TH400 setup you'll see about 20% losses, manual cars around 15%.
If that turbo will do 1,500fwhp without creating excessive back pressure than it most likely will do more if you lean on it.
I may have been mistaken on what I was told about the S484 as well, it might have been 1,200fwhp and not wheel hp because at 1,200whp that's 1,500wfhp and I don't think that's possible with the S484 now that I think about it.
I could be wrong, I'm most certainly not an expert lol.
Another vote for the Huron T6 kit, I am running a Huron S480 with mine. Jon even offers a modified hot side now that will allow you to keep AC with the T6 kit. Turbo blanket is off in this picture, I was doing some work, but I wouldn’t run without one.
Looks good. You have that thing looking really clean under the hood.
Thanks. When I did the turbo build, the Terminator X had just came out. I opted to not try and piggyback it, ripped out 100% of the factory wiring, re-wired the car from front to back using leash electronics stuff.

Nice, that explains why it looks so clean. I heard of leash, I will have to look into their stuff. I am trying to decide on ecu. I have HPTuners, but the Terminator has nice transbrake, 2 step, and boost control from what I have read.
