"Best" Supporting Mods for Twin Turbo Street/Strip

[RebelTX]

So I tried a search and came up with a few results but it was mostly about what boost is best.... I had a single turbo S197 mustang and loved the boost but hated the lag. So, to the point, im new to the S550 and IRS parts but plan on throwing a twin turbo kit on my S550 so I am looking for advice on supporting mods.

I am pretty much sold on going with a ON3 gen2 top mount twin turbo kit. HP goals are around 800HP if the stock engine can take it... I'll build a forged one down the line.... anything I should avoid or look out for?

For suspension I see lots of people using the "stop the hop" package from Steeda, is that a good option? Do you need the adjustable links?

I am thinking I want coil-overs on this car. I had adjustable shocks & Struts on the last car and it worked well but I always had rattles. I think a good set of coil-overs would reduce NVH but accomplish the same job, is there a good set for a decent price? Not looking for the cheapest option, but dont need the top of the line either.

What are other things I need to consider and be aware of when lowering the S550?

What are some popular intake manifold and throttle body options? Things to avoid?

Power limits of the stock fuel system on 93 octane and E85? When are injectors and additional fuel pumps needed?

The S197 had a weak drive shaft, does the S550 need a one piece to hold the power? I'll probably do this regardless but good to know. what about axles?

Front wheels... What clears the 4 piston breaks? will a 17" wheel clear? any ideas what a s197 wheel would look like on the S550?

I am sure I am missing things here and I would appreciate educated opinions on mods I should be throwing on the car as I prepare to turbo it in the coming months.

Thanks!

Stop the hop kit from Steeda, or the BMR equivalent is one of the best upgrades you can make. Above just over 700whp, you should be on e85. You will need a fuel system for that, and there are many ways to put one together. Rear half shafts are a good idea, but you can always do that when your stock ones break.

Good axles
One piece driveshaft
Opg and crank sprocket
Fuel system
Bmr suspension kit
Viking shocks
Driveshaft loop
Boss intake for boost

Don't know if you're automatic or stick. If automatic, be aware that at 800 hp, the input shaft and clutches are probably gonna let go. I'm at around the same power on a Hellion kit and my input shaft broke on my second trip to the track (not even launching hard btw). My clutches were also toast. Upgraded to billet shaft and Exedy clutches and have been fine since. Definitely the opg/CS like others have said. Also a boost controller (and some sticky tires) help a bunch on the street, as you can adjust the boost down at lower speeds because that much power is tough to put down on the street otherwise, and downright dangerous at times. I'm still on stock axles without any problems after at least 50 passes at the strip, although I haven't ever really launched all that hard due to lack of traction, which is probably part of the reason they still live lol. One other thing, I don't know how the piping on the On3 kit is run, but I wouldn't want to lower my car due to the pipes hanging down fairly low. The weight of the turbo system lowered my front down anyways, so it looks lowered on the stock stuff. Good luck!

We run the stop the hop on all our cars and are very pleased with it

We have a couple great options available for the cars, don't rule out air either

What are other things I need to consider and be aware of when lowering the S550?

the steeda adjustable camber arms, and caster camber plates are a good idea

What are some popular intake manifold and throttle body options? Things to avoid?

the 18 manifold or gt350 work great with a turbo setup

Power limits of the stock fuel system on 93 octane and E85? When are injectors and additional fuel pumps needed?

you need one of our fore fuel systems for e85, boost and e85 isn't safe, why spend 40k or so on a car, 10-15 k on mods to make it fast and look good, and skimp on fuel, 1 of the 2 main things that make a car go..

The S197 had a weak drive shaft, does the S550 need a one piece to hold the power? I'll probably do this regardless but good to know. what about axles?

depends on how your driving the car, for driving, both are fine oem, from launching at the strip, both are a good idea with alot of power

Front wheels... What clears the 4 piston breaks? will a 17" wheel clear? any ideas what a s197 wheel would look like on the S550?

need an 18 for the front, s197 offset is .5" difference, they will stick out more

I am sure I am missing things here and I would appreciate educated opinions on mods I should be throwing on the car as I prepare to turbo it in the coming months.

Thanks!

I’ve been looking at the on3 kit for a while also and was wondering what you’d recommend to buy with the kit for a 15 automatic base Gt. Also how difficult is the install on this kit?

give me a ring tomorrrow and we can go over your goals and help ya put the right thing together

Any turbo kit will be great for the car.
Top mount kits are awesome for how you can see the turbos and look really good when you pop the hood.
However I have seen them have problems with heat in the engine bay. So header wrap and turbo blankets would be wise.

Mid mount kits are great in that they don't create any extra heat under the hood. They don't hang lower than the K-member and are also much easier to install vs a top mount kit.
LPF, Aldo welds, and Hellion are the top 3 shops for mid mount set ups.
I went with LPF as he's had my business since my first S550 ( on #3 now). His kit is proven throughout the coyote world that it plain and simply works. The same kit I have has been 7.9's @ 175mph

As for supporting mods here is what I have to run 9.0's on 11lbs(roughly 14-15lbs on a 15-17 s550 with the same kit):
FIC 1000's, LPF dual pump fuel system, Ford Performance by gforce axles, Boundary OPG/CS, Eboost2 boost controller and a MSD 2 step.

As for suspension completely stock. With a good set of tires you shouldn't need any suspension work as the stock suspension is already very well set up.

For your trans you will need billet input shaft and exedy clutches. You can also do billet planetary if you really feel like spending money. Also don't forget you will need a stall. Circle D is where most people go for this.
If you're going to be leaving on transbrake then a one piece driveshaft will be needed as well.
If you're foot braking then the stock driveshaft will be fine as I've done 20+ runs with many of them being 1.3 60's

Most people run 17's in the rear with 305/45/17 ET Street R's.

800 is very achievable with everything mentioned.
With everything that I have for mine it made 950+ on 11lbs.
I have seen other cars (15-17 s550) at LPF make well over 1000whp and the only difference between mine and theirs is they had a fore fuel system. Capable of around 1200-1300whp

Great info, much appreciated.

I have a bunch of heat wrap still from the last build I will be sure to use to combat heat.... I have been looking at fuel systems and I think Im just going to do it once and go with a Fore 2 pump kit and ID1050X injectors. I hear the ID1050X has great street manners like the ID1000's.

I'll probably do a drive shaft and hope my hoosier 315/35/17's will soak up enough of the hit to make the stock axles left... just seems like something ill have to break before being convinced to spend $1000+

I blew up a 6R80 in my last car with a stock converter, my issue is always finding a good builder that can do it in a reasonable amount of time and not charging $1000+ in labor.

Stoked to hear what people are getting away with on stock suspension, its crazy. I want to do coil-overs I think, had all adjustable stuff in the last car and it rattled terribly but would hook in mud so i guess that was the trade off
