Those pics are sweet dayna! I love the rx3!
keep us update in the project.

P.S i din't know you where a mod in other forums.

you should so give me that car when its done :)

oh and the miata looks nice by the way, got plans for it?

this car need a 13b
i have one for my rx7, it comes from a 74-75 rx-4
very nice project tho

The car came with a BRAND NEW 75-78 13b from a rx-4, cosmo, or repu, but I sold it to a friend.

I'm putting a N/A TII engine in it.

why an n/a T2 engine ?
74-78 13b port configuration is the best to use in n/a form, no ? i'll use my s5 n/a rotors in mine, along with some porting. then i'll try to find a carb upgrade or i might go turbo with a sterling or something like that

My S5 turbo engine has 9.0:1 comp ratio vs your 9.2:1.. your rotors weight 11.58 pounds each... mine are 9.54..

port config is nice on the 74-78 4p 13b but to many peoples dismay.. it will actually produce more power and a smoother. faster reving powerband. than the older engines. One secret is the flame front of the S5 rotors over the older style.


Is your engine apart right now?? If so, I really really want a set of the 74-78 13Brotor housings.. I am building a differen't engine for this car this winter. I think having the original era rotor housings would give it abit more class. I know of a complete running/rusty RX-4 i can buy. I'd hate to buy it just to take the rotor housings.

I have tons of engine stuff in my core bank incase you wanted to trade for something or just incase you need something.... eg S5 N/A rotors, or complete rotating assembly w/ S5 rear c-weight. Pile of 12A's, and TII cores.

my engine is still in one piece and is currently hanging in my FB's enginebay. the oil pan dont fit.
i have my old s5 n/a engine appart and i will use my 9.7 compression ratio rotors along with the rotating assembly i'Ve kept when i'll rebuilt the 4 port.

i've always been told that if i wanted to use a T2 engine N/A i'd have to go bridgeport to compensate from the lack of boost. and that the engine would never run like an n/a 4 port anyway. its only what i've heard though.

BTW, i beleive my 13b 3b (its what the engine is called) rotorhousings would not fit 86 ++ side housings waterjacket, you'd have to use 12a or s3 13b irons to match them.

i've got pictures of the port size difference between my engine and those on a 6 port, i can post em if u want to see.

yeah i know all the interchanges. i have several 12A cores.

for example.. when you reassemble.. i would use your 4p e-shaft.. and the stat gears from the S5

lol too funny

and what about the miata dayna?

hey dayna is there any resources that can tell you all the interchangeable parts in the different years and engines?

yea flex there is... its called dayna240sx lol

she should just make a thread with everything and have a mod sticky it, that'd be sweet

that idea has my vote! :D

pretty please dayna

my vote is there too .!!!

there is alot of things to learn.. if you have a question just ask.. PM or contact me via AIM.

She's my master!!^^^:naughty:

haha. great deal.

Now, as I accidentally walked into my fellow colleagues' room to discover a display of love with his girlfriend just now, I suddenly came up with the thought of the usefulness of the 20B going in, well, pretty much anything. Did you guys consider doing anything with a 20B with this rx or any other vehicles at all?

and i really did walk in....ooops

20b's are too heavy. Especially to put in a 2000 lb car...

Nice RX-3! I love the later nose with the early bumpers. My second RX3 was like that, as well as the IMSA RS car I crewed for. My first (and favorite) RX-3 was a '73, so it had the early nose.

Mine ran a street ported 12A with the Racing beat holley kit, and a Holley 600 Double Pumper. With the big carb, big exhaust, and a lightened flywheel, it didn't have a lot of oomph down low, but it really screamed at higher rpms (the trick for autocrossing and drag racing was to keep the upshift buzzer on. If the buzzer stopped buzzing, it was time to shift into the next lower gear!)
