10A engines were PP as well.



I wonder if anyone builds those up these days? I'm sure there's some crazy guy in Japan running 10s with one.

10a's were not pp, they did have pp housings back in the day though. its really hard to build a 10a just cause they are so rare

You quite sure they weren't PP?

well sure enough, and i've seen that page b4 too, just didn't remember - i just thought i remembered in the R&T article about the cosmo sport a while back that they were pp.

they had cosmos with pp motors, they had em with semi pp too, its not like we see 10a's everyday

Are D ports worth the extra money?



I have spoken to two engine builders who recomend them for Turbo Aplication but what is the diffrence between the D and a std Round port (other than the price).



I have attached a NA D port as an example but i will be doing a Turbo that is smaller.



I am Intersted in doing a D port and the guy whos making the E-Shaft says he can do the Housings but being an enginer rather than a engine builder he does'nt know the advantage (he says Mazda would'nt do it for no reason?) so i would rather get them done by somone who has experiance with them.

 

Its a timming thing.Its abrupt start but you could round it out, however the volume would be reduced .(if its really relevent)You can move it up to change the timming.

I guess you are building a drag car or GT2 road race cause ethat thing aint gonna be on the street.

 

Yeh that Housing is a bit of a Monster, but i'm after somthing a little more Drivable (Smaller).
