FD twins, Sequentially. Rtek. FC block.
i first put the twins to a spare fc block in 2011..
i've been driving it off and on with twins not boosting for about 4 months... in the last few weeks this control system has come togather to enable something i can't even tell you what it feels like. i dunno, a single turbo? it's smooth
the valves are evap 2 way that came off 02+ sentras. 4 of them run the big valve under the turbo, 2 for vac/pres, 2 for vent when 2nd turbo is off (these hook to pin 87a on the relay so the valves open with key on). then at 4krpm egr output of the rtek ecu clicks the relay over to both turbos. the relay also opens the valve on the y pipe and closes the 2nd turbo bypass.(it engergizes them with keyon, and removes vacuum to both valves at 4k. thus opening one and closing the other. the waste gaste and pre spool just off MBCs (2) one set at 10 and the other set at 7. later to be 17. after a clutch uprade.
it took a lot of reading and understanding to be able todo it.
now i can use what i learn to build a ht12 /efr 8367 seq setup.
i don't know what more to say other then, dyno soon, getting a brake overhaul and some tires.
other stuff: 800cc primarys 720cc secondarys, going 800/1000.
9.4:1 compression rotors. 87 octane will move to 93 for higher boost. runs about 10 degrees of timing, 6 around 4k. arc top mount modded for better fit. also y pipe was lengthend...

Holy crap!
I admire your persistance!..now go forth and Multiply..heh!
If we get more of you we may be able to solve this wankel problem once and for all!..lol!

Awesome work getting the twins to function properly! A lot of people can't even keep them working correctly in FD's!
If I read right you're planning on running stock twins at 17psi? Thats well outside their efficiency and they hold a lot of heat, it seems like you're asking for trouble especially with high compression, on pump gas and a tmic.. Are you planning on running water/meth? I'm sure there's a method to your madness, I'm just curious what it is!

IM tellin you.. it already has gone before like 4 times... one time bc i ran 87 on my 93 tune by mistake. one time cuz i broke off the map nipple.. one time cuz i had a stock ecu instead of the rtek because i was testing it and forgot to swap back..., and i pick up the pieces, source new housings and go again.. but for real that was on the stock ht 18 and boost creep has been the biggest demon.
the plan is to keep it around 10 psi until the snow lets up, its alotta fun being in 4th gear throwing powder and building boost.
i will go water meth(yes you guessed it) and lose the tmic for a v mount setup.. then march towards 17 psi while watching knock, egt,afr. i suspect im going to run out of injector.
the current gold engine in it right now was assembled from well the housings and rotating assembly came from a 110k miles automatic that was rebuild stock and ran in my convertible for 3 years before i was on a 700 mile trip and at 625 miles in the rotors glanced the middle housing.. losing compression.. that engine was pulled apart the rotors re clearanced and repaired(C=) and then put with some spare 4 port irons to build this gold engine. is all in all it's a double rebuild with like 150k miles on the housings and rotors... starts/idles like a mazda reman i had in this thing when i got it though.

Sounds like a good game plan. I personally would ditch the 87 octane because I don't like the thought of popping motors and its cheap insurance.
How do you like the 4 port high compression in comparison to the 6 port?
Regarding running out of injector, I saw one of your other posts, I was able to run my 6port turbo on the rtek with 960/1600 injectors on the 720/720 setting. Car was very tunable and ran great on this setup until I ran into electrical problems.

87 is my staple tho. i want to daily drive it( an enjoy every minute of it) and 93 octane is always 50 cent per gallon more. i will always run 87 on the street. however i dont need 17 psi /meth on the street either.. guess dual fuel tanks could be an option... but i will probably never run the 17 psi except for DGRR the day i take it to the dyno, and the day i take it to the track.
thanks for the info on the injectors i remember your setup and i m suprised to hear that you didnt run in the 9s with when the 2nds come on.. could u get it into the 11s at least or 10s? i'm shooting for 12.5 by 3k, and 11.5 after that. about to tune negitive split idle, try some rx8 plugs and shoot for 15.1 idling. now sure were to find rx8 plugs in a range colder though. i m on stock plugs cuz i dont really know better to be honest.

you should be ok with those injectors, i'd be surprised if you could squeeze out over 350whp from the twins, only those who extensively modified it managed more.
but at 17psi, they really won't last long if even more than a few times seeing that boost. so take that how you want.

titanium tt is my hero. his 400+ was on stock twins not bnrs. he also bragged of a 1700 rpm spool.. i have 10psi at 2k, but not before it.
i have some tricks. one is a fresh rebuild with new housings, and the other is_________?
here is my new 3 inch exhaust. first time doing this much at once, so far i have welded a few bends and mufflers on. nice to have a bending/flareing machine and mig and rack at my disposal. comes with the trade.
also new master cylinder and rear calipers.
wish i had a video of 5th gear at 5k rpm in the parking lot.(note 3.909 N/a LSD)
