Okay this is a complicated question. I bought a turbo kit from some guy for my 94 si, now that kit had a fmu, instead of the black/blue box... I dont know which fmu (12:1..8:1) but I do know the car ran good (along with checkvalves). Now I am going to put the turbo kit on my b17 92 gsr, but I want to know if I should be okay with the fmu I have or upgrade the fmu because of the larger engine, even if I am using the same turbo kit?


thanks

He probably had a 12:1 fmu...Open and measure the disk then post up the diameter i can then tell you what ratio it is.Use the 12:1

 

one other problem you will run into is, that manifold will not bolt up to your engine,the sohc d series have a different bolt pattern then the b series..

 

I will probably open it up this coming up wednesday (my day off) but I know that it should be about ~2.83" if it is a 12:1 right? I was just conserned if I had to worry about fuel changes between motors or turbos, but I guess its turbos.

About the manifold, I did some research and found out that this manifold will bolt up with very little modification, it was origionally intended for the d16a8(dohc zc) and was later modified for the d16z6, so I should not have a problem, thanks anyways for the lookout.
