If you can get the parts for the MS, I've been trying to get the error* daughter board kit for four months now, with no luck. Glens Garage has been out and I’ve had no luck else where.

Probably best to go with a 550/1000 or 720/720 setup. Of course, bolting the TT setup of an FD onto an N/A FC is a pretty "hefty" task so this is probably the least of your worries...

i'm assuming youre not going to try to run them sequential... i've heard that the fd has a completely separate book for the mass array of vacuum hoses it takes to control those things. Should be sexy as hell though if you get her going good and clean.

Am I ignorant or will this never work? FD twins are vacuum actuated, which means without the vacuum lines they may not be run sequentially. Also an SAFC will never be able to properly control a turbo on its own, especially when running an NA ECU. Plus you are using the stock NA engine??

sounds like a disaster waiting to happen. Would be cool to see if you pull it off tho. Definately something i would be interested in. I would like to know how everything is done and what it is pushin. I like NA, but turbo is the ****. If i had the money i'd do it. :-D

Wow, If you pull this off and have the engine last more than 5k miles I'll be impressed.
Anyway
That spacer is a beast!! lol That thing looks pretty strong
I'm interested in pics of how your going to fit that in there.
Sequential sounds like a nightmare.
Unless your mechanic labeled the vac hoses he specially designed I doubt you'll run them sequential.
I would highly recommend a full blown EMS. The SAFC will manipulate fuel but timing will still need to be controlled.
A Rtek might even get it done.
Good luck and be careful getting that thing tuned.

SAFC is not a good tool for what your trying.
Get the rtek 2.0 or go full EMS.
Honestly your taking on a big project and your making it harder by using the stock ecu.
You first have to be careful because your using higher than normal compression.
Then your using higher than stock HP turbo's
Then your relying on a piggyback fuel manipulation to compensate for the increase.
You will also be limited to 550cc stock TII injectors as primaries to keep it drivable/good during start up maps.

Be careful what you're implying...
A stand-alone EMS is highly recommended.
Yes, the set-up can run on the stock Turbo II ECU, but it's not recommended.
The twin HT-12's have a lot more airflow potential than a single HT-18.
If this thing starts to blow engines, I would not be surprised.

The stock 13B-REW sequential twin-turbo system runs at 3 stages.
It uses electrically control solenoids and vacuum to control acutators.
I think one stage is progressively controlled, so it's not just an on or off thing.
How do you control such a beast when you yank all the vacuum hoses and solenoids off?
What you're describing sounds like a NON-SEQUENTIAL set-up.
I think you're getting the terminology confused.

A word of warning: The FD's twin turbo setup is one of the worst things ever concieved. Don't even think of running it sequentially unless you can build the control system (actually not that complicated with a small microcontroller and a few solenoids) and deal with the ~70 vacuum lines. In addition, these turbos save known to have a very short lifespan. Most of the used turbo sets on the market are either at the end of their life or close to it. Generally they start puking oil...
Anyway, looks like a great project. I'd highly recommend ditching the NA ECU and going with a standalone based on the amount of air those things will push. For the stock TII unit, the NA ECU is fine. Start getting into more airflow and larger injector sizes past 720CC or so and you run into problems with idle, daily drivability and the like. You know the downpipe will run into the frame rail, right?
The only ones I've seen have not been completed. They get to the stage of bolting on the turbos, find out that the downpipe and intercooler plumbing is a nightmare, and then give up.
When he fabricates manifolds from scratch, then we start to talk.

If everything goes well id say you be beating out Aaron here for custom work with those twins on an N/A. Thats a lot of work.

I think some are confusing sequential with non-sequential. Sequential is when the first turbo spools, then the other comes on at a certain point in the case of the FD's..sequential/sequence...bleh.
Non-sequential means they will run at the same time, which IMO would be better.

Are you doing your own work? B/c if you dont know about turbos and you dont even know the basic concept of sequential and non-sequential setups.... Then you are in for a good headache... But trust me, it should be too hard to fab. As long as you know how to weld and have your own tools... with a set of ***** to back it up... Good luck, bro. Make us FC owners proud...
