M2 Twin Ball Bearing Turbo Setup Up And Running
Well, it took long enough. But it`s up and running now, to say the least! Zero lag. Boost in an instant. M2 says it should be good for around 20psi of boost. But right now I am just using an M2 stage 3 ECU so I am only running 12psi of boost. Once I get a fully programable ECU and big injectors I will start turning up the boost. I have a J & S knock senser with the air/fuel monitor. The air/fuel monitor always reads rich under boost with no indication of knock. So far so good. Now it`s time to play with it a bit to see if there are any bugs to work out and take it to I dyno to get some numbers. Stay tuned.

As I recall Want2race`s turbos are custom. With the secondary being bigger than the primary. The M2 set up is not like the Pettit 10- 15% better flow system. The M2s snails are bored out 7mils over stock and each turbo is rated to 400hp in a piston engine. When I ordered them Brett at M2 said that the ball bearings let the wheels spin so easily that you could blow on them and they would spin. I thought sales hype. So the first thing I do when I get them is to blow in them, guess what? The wheels spun!
And Yes JoeD, the car does accelerate much quicker. I get to 60 mph so fast now that I have to keep a close eye on my speedometer around town.

JoeD, I can`t say for sure which turbo set is better. But the M2 sets should flow more and as I recall the Pettit sets are not ball bearing so the M2 sets spool up faster.
bbeavers, the turbo set is $2995 and they come mounted on a manifold. M2 claimed they are a direct bolt up but we found that some reworking of inlet pipes was in order. Which in the end let the turbos get better air flow into them.
Jason, I went with high flow twins for a couple of reasons.
One, I just like doing thinks a little different from everbody else and two, it looks like I can get the hp I want without any lag problems. I looked at most of the single kits and it seemed to me in the end it would cost just as much to set one of those up right as it will the high flow twins. Remember, the set of high flow twins was $3000 and the better high hp single kits all seem to cost more than that. As far as stress on the motor goes, I doubt I will need much if any higher boost psi to make the hp I want with the twin setup as opposed to a single. These are high flow just like a high flow single. So I don`t see why they would be anymore stressful on the engine than a high flow single.
maxcooper and Alpine, dyno slip will be coming. But the local dyno closed and the nearest one is about 50 miles away. So it may be a few weeks before I have the time to get up to it.

Number of happy Ball Bearing Turbo owners = 1
Number of Jelous FD owners with the stock twins = countless
I also think it's a great upgrade. I do some Autoxing, although I haven't been able to go in a while, and lag is certainly a no no.
Let us know how much boost it will take for you to reach 400rwhp when you dyno it

Those sound awsome. I also have a question about them, might be kind of stoopid so please don't thrash me. Are these completely new turbos or do they rework the factory turbos so they are ball bearing and flow more. Also where can I find these. I am interested in staying twin, for lag purposes, and this sounds perfect. The help would be greatly apriciated.

and they come mounted on a manifold.
Please give details on this!

Bigger and better things
I had some of mine... lost now..
I get full boost with a stock cat and stock catback! And stock intake and intercooler @ 1800rpm (10psi)!
Now anyone that knows physics should know that a mp and catback would make my setup CRAZY! It would be full boost all the time!!!
Mine are custom and add me to the happy owner list.. Mine weher x pensive but a single needed too much support **** for me... I still need an ecu then ill install all my other mods..

50tooslow, Thats a good question. The snail housings appear to be the same size as the stock ones on the outside. But the inlets and outlets are much larger. They`re from M2 so if you call them and ask for Brett he can answer all your questions. 925-686-9047 please tell him I gave you the #

cewrx7r1, Yes they came mounted on a stock manifold and I have no creep. But I am also using a GReedy PRofec B boost controller which, from what I understand, would cure boost creep too.
Bacon, The turbos are installed and I did not take pictures of them before they were installed. Doh!
