i have a little 12a but ive talked with the NSW Road Traffic Authority (registraion) and they have no worries about me putting in a 13b

ok its 15% more power but its a certified mazda part

the worst problem (if any) is getting an engineer to sign it off - so im not worried at all



anyway what gen 13b should i have

and what could i do to it later

its a 1979 model

anything series 5, or 13B RE from a cosmo.

they all fit with about the same amount of work, you just need to decide if you want a turbo or not

yeah a 13B-RE a S5 13 NA or even a juiced up 13BT will make a 79 move.Just look at '79rx7's car on his thread here.He has the S4 EFI and NA motor in his 79 and is hitting awesome times for basically a stocker engine with some bolt-ons.

That's the "Quarter mile times" thread

so to clear it up any thing in 13b 5th series, right?

ill just keep it stock for the moment

j9fd3s

thats prolly the most common one, so it shouldnt be hard

Yeah, because we never got a 13B in the gen 1 cars, you basically use either a s4 or s5 engine, N/A or Turbo. s5 is a more popular choice generally, because the engines are a bit better (bigger ports from memory).

I'm getting a s5 half-cut for my s3 soon.

So you're getting a S5 T2 then drifter?Hows the resto coming?
