If you want to run a carb on a 2nd gen engine then just buy the manifold from racing beat.

 

Believe me, I am too

I believe you could get the entire crossmember and engine mount cross bracket out of an SE in a junkyard.

 

i dont think theres enough meat to do the full 20mm there, but if you slot those, and the ones in the crossmember and the trans mount, that does it.

thats the really old school (pre gsl-se) way to do it

 

You need:

13B oil pan from an SE

Front cover from a 12A or 13B SE. Main difference betwen the 2 is the 12A has 2 MOP lines, SE has 4. If you're installing a 2nd gen engine, I'd go with the SE front cover to run 2 lines to the block oil injectors and 2 lines to the fuel bowls

Upper intake manifold, (UIM), from Racing Beat and a 48mm side draft carb, Weber DCOE, Delloro DHLA or one of those 48 mm side drafts that Robert sells.

Upgraded carb style fuel pump, 60-75 gph output range, and fuel pressure regulator.

Fuel pressure gauge.

Flwheel that came with the engine.

225 mm clutch/pressure plate from any 83-88 RX7.

1st gen tranny, 81-85.

 

Not only does racing beat sell the side draft upper intake that attaches to the factory lower intake, but they also offer an intake to use a holley carb on the 6p 13B.
They also sell an engine mounting plate made for putting a 13B into a 12A chassis, although you can modify the 12A plate.

This swap has been done numerous times, sometimes utilizing the FI system, other times a carb.

One thing that hasn't been mentioned, but the exhaust manifold/header is different for 12A and 13B. Exhaust ports are further apart on the 13B, so you will need an exhaust manifold or header for the 13B.

 

ok, well i was also told i could use the 12a oilpan. and i already got the 12a oilpan and front cover so thats what i want to use.

i like that intake you mentioned, just need a carb to go on it if i ourchase it.

i do need a fuel pressure gauge, already have upgraded fuel pump and regulator.

i do need a 225mm clutch and pp, since my 12a is a 215mm(blah).

and i already have the 1st gen trans.

so right now im about halfway there on parts. just need to get a few other parts. roughly 500 bucks worth or less if im lucky.

 

12A oil pan is a no-go. It won't fit a 13B. Same as exhaust. 13B is longer than a 12A, therefore intake, exhaust, and oil pan will not interchange.

You will need a 225mm clutch/pressure plate.

Fuel pressure guage is not required, but highly advised.

 

ok, so will i be able to reuse the current 13b oilpan that came on the 87, or will i have to hunt one down from a 84-85 13b? more than likely i get the feeling you will tell me the 84-85 pan.

ok i can just order a clutch disk from racing beat, and attempt to find a stock pressure plate. im sure someone may be able to help track down some parts. i will make a wtb thread in the 1st gen parts section later when cash flows in.

all of what im doing now is research. which i do thank you for helping.

***turtle edit***
can you tell me more about this "robert" character and what he sells and where i can contact him. also, above with the clutch disk/pp, do you think it is a good idea?

 

Oil pan, yes, you NEED the 84-85 GSL-SE oil pan. They can be found used, or ordered new from Mazdatrix and racing beat.


As for Robert, his username is 640rwhp12a (or something like that) and he owns a shop called rotary shack. Sells lots of trick stuff for rotary engines.

 

If you do it that way, hopefully the driveshaft will still have enough clearance so it won't crash into the rear seal during normal suspension movement.

 

Holy crap did i seriously ask the same questions 2 times.

 

Ok man if your doing the Turbo 2 swap on a FB the best thing to do is use a GLS-SE oil pan and the front timing cover. As for the front bracket go on www.mazdatrix.com and purchase the front bracket especially made for the Turbo 2 in the FB swap.

p.s. Also letting you know that if you have a S5 Turbo 2 your car will run on Lint mode meaning that the second rotor will not be lubricated the proper way because the turbo 2 S5 front timing cover is not mechanical. 12a, GSL-SE 13b, 13b and 13b turbo S4 all have mechanical front timing covers. The S5 Front Timing cover is electronic meaning that when you put the GSL-SE timing cover its not going to work right. Theres two options your have.... Go stand alone (Microtech) or get S4 Turbo 2 wiring... (Chassy and Motor wiring) GOOD LUCK MAN

 

This should fix it.
