which engine

[DarkHadou SP23]

time to start working on my 1983 rx7 but wondering which engine to go for. i was thinking of a 12a turbo but maybe i shold go with a 13b na i dont know. which do you guys think would be better? and if you guys have any other rotory engine Suggestions feel free to post

thank you

go look for a 20B from a mazda cosmo, its a three-rotor one, but it only comes with an auto box, a manual one off a 13b should bolt straight on, but you'd need to fabricate your own engine/transmission mounts.

20b would be nice. a TII 13b would be good as well. If you want to stay affordable for a good new rebuilt motor, look at a 13BT should run you 3000CND.

thanks guys
does anyone know where i can find a S5 TurboII engine?
thanks

[Capt.Moe]

S5 Turbo II Motor?

Not sure what the hell that means, but one would imagine perhaps a rotary specialty shop (assuming the S5 is a rotary)

If you live in Canada? Try the Rotary Specialists in Calgary. But other then that I do not know?

JDM MAZDA 13BT S5 TURBO II ROTARY ENGINE

so if any of you have any advise please post
thank you

[Capt.Moe]

Uhm, you could take the trip to Canada and see FDTT, from the sounds of it he's good, and it's not too expensive either.

S5 = 89-91 RX-7

if youre hellbent on swapping, i'd get teh S4 (86-88) motor, theyre cheaper

[FDTT]

Um JDM VS USDM TII motors are exactly the same with the exception of the Enfini cars.
Unless you have some money to be throwing around i suggest you put a 12A back in there.

PS the 12A is not the best to turbo, but can be done.

well they are mostly the same, but when i took apart my jspec s4 motor, the fuel rail was different.
the fuel rail is better designed imo, because the pulsation dampner has a different locationg

[Capt.Moe]

How does it really make a difference where the Pulsator is located?

[drftk1d]

because in the US spec location, the pulsation damper might leak and spill fuel on the exhaust manifold (very hot) and cause a fire.

if you smell gas underhood, thats the first thing you should check

[FDTT]

The USDM and JDM engines are EXACTLY the same for TII's.
You may have had an S5 rail on a S4 engine.

I love seeing people say "ya its JDM, see no EGR there". LMAO, the hole JDM thing is a bit much now, especialy when i go to EBAY and see JDM parts for domestics.
