I know that these are basic questions but i was just wondering. I have searched the forums quite thoroughly but i cant find the answer to these two questions. And when i say what is our engine made of i mean what kind of material, is it cast iron or aluminum?

Thanks

 

it's made of both, the housings are aliminum, and there is iron inbetween and on the ends.

as for the injectors, I think it's in the faq, it depends if your turbo or non and I think it depends weather your an S4 or S5

 

86-87 13B NA, low square center, 460cc, red, 195500-1350
86-87 13B Turbo, low square center, 550cc, tan, 195500-1370
88 13B NA, high square offset, 460cc, purple, 195500-1350
88 13B Turbo, high square offset, 550cc, purple, 195500-1370
89-91 13B NA, high oval center, 460cc, red, 195500-2010
89-91 13B Turbo, high oval center, 550cc, purple, 195500-2020

 

ok thanks, i actually just found the size of the injectors. so that question is answered
thanks again for answering.

 

Sorry to bring this back from the dead, buy anyone know if the info about series injectors is the same for JDM?

 

Same. There are no differences. As far as what our engines are made of (too bad it's an old thread), the first thing that came to my mind was tiny little gerbils running in circles.

 

You can buy some aluminum end plates and intermediate housings to replace the stock cast iron ones... They're made by Racing Beat.

That'd result in an almost all aluminum engine aside from the eccentric, rotors, and hardware.

How much money you got?

 

mazdatrix also has some billet rotors that theyve been playing around with... $$$

 

1. Yeah i spent 8k on irons and rotors.

2. Cool, so is it running?

1. No i ran out of money.

2. ROFL.

 

Sorry i bumped this thread b/c my injectors in my turbo 2 swapped NA looked red, but they have the part number of the T2 injectors.. thoughts?

 

the injectors rarely are the color they are supposed to be, for many reasons, mainly heat.
