hi all i have a series 2 with a extended port 12A i am currently converting to turbo and FI im using the injection system from the 2nd gen 13bt and using a mircotech mtx8 version 2 computer to control it all its slowly getting there

Honestly I've had an idea similar. Just run the stock S4/S5 Turbo intake and have an adapter made to fit the 12A. Then just have a exhaust manifold made for 12A and 13B S4/S5 turbo. Then everything should work in harmony. Except I would never run the 12A with a turbo,

Us a MSII. Cheaper and better to mod. there is a Ausy company that makes a adapter for the 12A to bolt a s4/s5 intake on. http://www.tweakit.net/shop/product_...oducts_id=6313

That adapter looks really good. I guess you would need a GSL-SE center iron to get the primary injector ports though. Doesn't look like there is a spot for them on that adapter plate....

Verneuil

you could just have the bungs installed on the manifold and or on the adapter. It can be done.

thats the exact adapter i have ordered tweak it have been really helpful, i was wondering if i used bigger primaries would i be able to get by with out using the secondaries

Verneuil

Running bigger primaries will give u many problems. It'll be very hard to tune idle to be smooth and low. Id go to a fab shop and have injector bungs welded to the lim or use the gslse center iron or just any 13b would do it.

Not mine, and not entirely sure of the manufacturer, but quite relevant to the thread

Real nice, but next to impossible to make a fuel rail for it..

flight_of_pain

I imagine they intend to use rubber line to connect to a rail, like Z-cars.

Verneuil

Thats what i was gonna say lolz. http://www.aaroncake.net/RX-7/megasquirt/index.asp read through that. Its all about MSII the FC turbo 2. Since that pretty much is what ur doing check it out. Its work the read. And check out the MSII http://www.diyautotune.com/. Im using a MSII on my 12A FB to Fuel inject it and i will be goin turbo down the road.

I haven't checked in a while... but I recall that the megasquirt would not work with positive manifold pressure. I could be wrong though.

EDIT: Nevermind, I guess they do now..

Verneuil

Ken has really done some awsome work with the FW for the MS.

flight of pain that actually helps a heap i will be very different kinda lol spoke to an engineer he said he can put the injectors in the secondaries part on the manifold so it will be hopefully a clean job sorry if that doesnt make much sense its friday night and im having a few drinks

look at mine was done in this thread 12 a turbo https://www.rx7club.com/build-threads-293/my-12-bridge-port-turbo-rx7-931473/

i was wondering just out of curiosity if i would be able to run the injection system with out using the 13b CAS rather the 1st gen distributor

That is/was my equipment. It had absolutely beautiful throttle response BUT I could never find the source of some vacuum leaks and I eventually gave up on it.

How was this wired to run the injectors? Since there is 1 injector per port, how did the throttle body setup work? Multiple blades to open the secondaries later? Can you have MS turn another set of injectors?
