i have a little https://www.nopistons.com/forums/pub...1047683894.gif 12a https://www.nopistons.com/forums/pub...1047683894.gif 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



mike

im puting a S5 in my 84 with a carb/turbo set up

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



Raul

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

ill just keep it stock for the moment

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



mike

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. https://www.nopistons.com/forums/pub...IR#>/smile.png

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



Luis

Yeah, thats the plan. Apparantly from "Rotormotion" the s5 half-cuts are $2800.



I got a new boot from Mazda, but I haven't welded it in yet. Due to my lack of workshop at the moment, nothing drastic is happening at the moment. I've got to work out what I'm doing about the roof too, cos I can't get a new one from Mazda, so I need to find a non-rusty sun-roof donor car. https://www.nopistons.com/forums/pub...1047683561.gif

i wonder how much shipping would be? theres plenty of unrusted ones here, kind of a shame they are going to waste



mike

??

what about the GSL-SE? series 3 1st gen with a fuel injected 13B



Series 4 and 5 had more power, but the GSL-SE engine should be the easiest to install

That would mean importing, considering we are in Australia. All our 1st gens were 12A's. I am running a S4 13b in my '79.

https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

Yeah, we never got one. All first gens with 13B's over here have them from s4 onwards or cosmo's.
