Hi friends,...
i'm swapping my 12a to a 13b




BUT i have a BIG BIG BIG problem.. today the mechanicker have say that the exhaust header is not compatible!!!!!!!!! ****! why i have a FB of the 80 with the strange HEADER!


now i need very fast a new header.. and i wont know if thise: http://www.mazdatrix.com/e-gray.htm 16013 its ok ? then i need nothing else? its all compatible or? or easy modded for the 13b porting thanks a lot!!!!!!!



THANKS!! very urgent

 

Well, Im not 100% sure, but I think the header you have in mind will work, but you will either need to buy a presilencer, buy the catalytic converter pipe listed for that header, or have a custom pipe made so you can bolt it to the rest of the exhaust.

I hope that helps. Post again if you need more help, and Ill try and let you know.

No need to buy new headers. just cut the pipes at the joint and the flange (where the headers meet the engine)... with a slight trimming, you should be able to use the headers and just run new pipes.

 

oh ****

but so its better or? .. i think with the old one i have a dispersion of HP , why , the old header have a big sistem for pomp air for the emission law.. so without that.. its better a good clean one.. i think yes.

i hope all will be good with carb etc etc.. why i have no more money.
thanks.

 

Your order looks good, "mechanicker" I love it!

 

u bought just 1 spark plug?

 

I think youre looking good with your order, Scruch. I personally would get a new header rather than modifying the old one to work, especially if the old one was stock (you never said if it was or not).

So, basically, you should be fine with your order, but you may need something to connect the header to the rest of the exhaust with.

You dont have emissions there do you?

yes its enough or? in the pict there are 4 spark.. its ok ?

For t.j:
yes it was stock ! the strange header with airpump of the FB 80 Federal.. =)

We have big and havy emission.. but the mechanicker that do the check he print on my documents the emission test of a Mx-5 (miata) LOLLL =)

 

They don't have any Rx-7 shops in Italy? I would think shipping would be as much as your order.

You need 4 spark plugs.

Modifying a 12a header to fit a 13b is a very bad idea. You will have an exhaust leak because you wont be able to get the pipes to line up with the ports.

Wow, it sounds like you have a really cool mechanicker!

 

Oh Oh oki thanks a lot!

Here in italy are about 20 FD, 15 FC and 2 o 3 FB ... never its be sold by mazda, in italy the rx7, are all imported cars..
So a Rx7 shop is impossible to exist here, and rx7 skilled mechanicker too.

Rotary Engine the italy people havent never see. maibe only from thise year with the rx8! .

I have called henry (mazdatrix) he have modificated my order and added 4 sparkle! 2 type different for the 13b that need 2 different type =)

 

sounds good. you'll be drivinicking in no time
