Pics of Exhaust sleeves in a FD vs Cosmo..???
 

Hi...

Does anybody have pics of the exhaust sleeves in a Cosmo engine vs a FD engine..

I know there is a big different in the size of these two engines but i need a picture of the different or the size in cm/feet...???

I have a cosmo engine in my FD and i want to make the exhaust sleeves bigger so it is the same as the Fd engine....

Thanx

How do you know you have a cosmo engine in your FD?

Either way, the best way to get FD style exhaust ports in a cosmo motor is to buy NEW FD rotor housings. Porting the sleave will eat up a lot of porting bits and requires disassembly of the motor.

I know i have a cosmo engine because i did buy it myself from Japan and i could se that it was not the same as a FD engine... And it is now in the car...;)

Where can i buy new FD rotor housings...???

Thanx

Here's a old thread by Michel showing a photo of a cosmo exhaust sleeve.

PM Michel (rx7tt95) He is a photographer by trade and I am sure he has more photo's comparing the cosmo/FD exhaust sleeves.


Hope you get it all working by the end of May?
