No I did exactly that. I ran a line from the compressor, then split the line to each turbo. Still had overboost, but this was before I found the leak. Been at work all day so I haven’t had a chance to see if fixing the leak fixed the overboost.
This looks great. Would there be enough room for the cats?Also I have a set of custom 2 3/8” down pipes for a S550 3.7 ecoboost build that I would sale. I’m not going to use them.
They are made of thick stainless scheduled pipe, with a flex section and connect to the over axles, they work fine (what I used for the initial tuning on my car). I went with bigger down pipes and exhaust because my turbos are bigger. Again these are for S550 3.7 ecoboost builds and will bolt right up. PM me if interested
No the cats are deleted for a good reason on the EB conversion. You have to remove the flow restrictions or you risk longterm engine health (think pistons). You could add some hi flow cat cells at some point in the stream but i wouldn't recommend it.
Here is my answer from the post:
The twin turbo game is not a plug and play for our platform. Really only two options. Build your own or get a shop to custom build. All the road course guys I know are om procharge builds. I am currently in the midst of a custom top mount twin turbo build that I will eventually run on road course. These engines respond well to properly tuned boost application. They do have a weakness in the pistons/piston rings if not properly tuned or run on continuous hard runs at high boost. Most have run 500-550whp / 400 plus TQ for many miles without problems. All about insuring good engine temp and e85 fuel or better at those numbers. The 3.7 is great fun with a proper suspension build and good turbo build. The lighter nose and high revving cyclone engine has potential.
If you had it to do all over again, would you buy a v6 for this purpose? The weight savings is what drew me in but after the power adders, how much are you saving? I'm limited to about 420whp @ a curb weight of 3600lbs and 93 octane with no meth injection. Does this sound like the right platform or should I be looking to the i4 or v8 instead? As previously mentioned, my last car was the 5.0 but I see potential with the v6. My budget after buying the car is about $15-20k.
S550 3.7L Stock Curb Weight: 3526 lbs.
Would you recommend a twin turbo or procharger setup for track duty?
For a roadcourse setup at the power levels you described you wont need to do internals. Complety unnecessary. If it's piece of mind you want then your looking at a MINIMUM of 3500 in parts to factor into your budget. Your talking rods, pistons, piston rings, and maybe new head studs. That's not including the labor. Super Six Motosports does sell a stoker kit that inlcudes rods, pistons/piston rings, and crank for around 4000. Cheaper at that point to buy a another motor, like I said they are cheap engines (can be found well under 2000). These engines are stout. They can take a lot of punishment. If you want a plug and play setup out the box the Procharger may be for you, but Procharger delivery is linear and doesn't come on big down low and doesn't have the track TQ you may want coming out of turns. However, it's controllable power. It's also about 8000 new with supporting mods. Twins will be dependent on the build and setup you go with, and again it will be a custom build not out the box. If your serious about turbos in track setup an oil cooler and an auto blip system (unless your heel to toe is on point) would be good. Upgrade your front brakes at minimum to the base GT four pots with proper pads and rotors. The 370z is lighter and has more neutral blance stock for stock, but a mustang is faster in the straights. Honestly, the Z is a hella of track car if tuned properly. Boost changes the characteristics of these platfoms in different ways. Good ways.
My number crunching left-side brain says go with the z car. I've been wanting one since the debut of the 350z. But that's not what I'm gonna do. I love the idea of an American-made, twin turbo v6 mustang and I was looking for someone familiar with the platform to finish talking me into it so I appreciate that. Bonus is that I still have some upgraded suspension components and a set of 18x11 ec7s. Not to mention my previous experience driving and upgrading 2016 GT. The 370z probably can't easily run a square fitment of 315 width tires either! (Don't correct me if I'm wrong lol ) I already reached out to the premier mustang shop in my area so waiting to hear back from them. I'm definitely leaning towards a twin setup but I need some help putting together a parts list. I saw the super six Ecoboost "kit" but I think there's gotta be a better way to do it. Someone mentioned sending off the stock turbos to get rebuilt in a previous thread? Any advice would be much appreciated.
