10th AE twin turbo on 13b-t, NOT 13b-REW!
Hey guys, i am attemting a conversion of a normal 88' 13b-t motor (ported and rebuilt) to handle a twin turbo setup (using two of the stock turbos). I know its going to take forever, but i think it will work. never know untill i try right? Has anybody attempted something like this before?

are you going to use 2 second gen stock turbo's? If so i think they will be a little big as a set.
Someone once mentioned that 1g dsm turbo's would work great in a twin turbo setup iirc

im kinda going for overkill what im planning on is a set of turbos where you have one on all the time, and secondary intake+ exhaust ports open up to spool up the second turbo. So in essence you will have two boosts, the second turbo will open after the first turbo is nearly fully boosted.

Why dont you just use a set of stock FD turbos? Youll just have to have a small spacer made to space them about an inch further away from the LIM. Bolt that right up, fab a few oil/coolant lines, and youre done. Im thinking of going this route myself.. Really not all that much to it, and stock FD twins can put down a good bit of power. I have a decently sized FC hybrid sitting here now though, just cant decide which Id rather use...

Very amitious indeed...good luck though. I agree on using the FD turbos or DSM turbos though. 2 FC turbos you crazy fool you!
Ha...FD turbos putting down a "good bit of power" last time I checked they can handle a bit more than a "good bit" unless you're crazy that is (then again you did abandon us N/A guys j/k).

I know of someone working on one.......last time I talked to him he finished building his manifold........He works/ed at Mr. Mazda in Campbell....he has the widebody turbo Vert.

Twin stock FC turbos has been done before, and have far more potential than FD turbos. An Aussie crowd have a fairly successful RX-3 drag car with this arrangement, making (IIRC) ~500hp. Here's the custom manifold they used, which they also sell at a ridiculous price.

OK, my bad, I didn't even see his second post.
fusion-turbo, don't bother even thinking about trying to make this sequential. It's far more complex than most realise, and the chances of getting a custom install to work this way are slim to none. Stick with the plain ol' simultaneous parallel turbo arrangement, which has proven benefits and is no more complicated than a single turbo install (just harder to fit in).

Anyway, if you have serious performance aspirations, the stock FD twin turbos shouldn't be considered. They have limited scope due to their size and difficulty to upgrade.

oh man i know itd be tough as hell but a full custom sequential twin turbo install would be so sweet. ULTIMATE badass points. hope you realy know how to go about this tho since it wont be simple, cheap, or easy to say the least.

i have a fair amount of knowledge on how to set it up and how to custom fab. the parts, but a "fair" amount of knowledge isnt going to get me by, which is why im still in the developing stages. Im planning on doing it sometime whithin the next year, but i need to secure another car first and learn all i need to know. alright tell me what you think... i dont believe theres any easy way to remove the MAF sensor, so im going to have to fab up a valve (butterfly most likely for reliablility) after the MAF to allow air to only pass through the inllet of the first turbo, and open up during heavy boost to allow air to pass through the secong turbo. The outlets of both turbos fab'ed up to a FMIC. The exhaust is where it gets tricky, im not sure, but possibly fab up a unit like the one shown above, or i am going to see if there is a way to fab two stock exhaust manifolds together to get the same effect. Another butterfly valve on an actuator would control the flow of exhaust gas into the port of the second turbo. I would wire the two valves (intake= exhaust) into the same line, possibly boost sensor? And at a certain boost the valves would begin to slowly open untill the first turbo is nearly bully boosted. I have it all written out, and i havent listed everything, but this is my first real custom job, tell me if you guys see any red flags already. Thanks!

You seem to want to do this the hardest way possible. You should definitely be using a standalone for this project, and even if you didn't (can't see it working well) all you need to do is split the pipe from the AFM outlet to the two turbo inlets. No silly valves and actuators. That's just asking for unnecessary complication and trouble. There's no way you'd be able to control is properly anyway. Like I said, sequential turbo control is far more complex that most realise.

ok?? what about just something like a massive wastegate to feed the second turbo when a set amount of Boost is reached?? Of course it would have to have the same inlet/outlest diameter as the exhaust pipe feeding the first turbo.. nest-pas??
*edit*then for the intake if you are going stand alone you could either y-pipe the turbos to a single filter but y not just feed each turbo by seperate filters??

i dont know if this will help any but i have seen what is baisically an exhaust valve for the use on trucks. its a big slider valve that is designed to switch between an exhaust path with mufflers and one without. i dont know how fast it opens, but at least it is designed to handle that level of heat and be remotely activated. IIRC they come in 3 and even 4 inch diameters so it would flow just fine. could be something to look into.
