Thread: 54mm CAS ....

AEM now has one just have to call them , I hope that helps ...anybody with the older dist.

No they don't. You getting me excited now are you telling me that AEM finally made a CAS disc that fits our 91-94 B13 SE-R. This is not for the RWD SR20's right? I'm calling them tomorrow!!!!!!!!!

they make one in 54mm for the gti-r now....I hope it fits

You had me all excited for a second. Well the RWD SR20's use a 50mm Cas Disc from what I remember the one that came with my AEM did not fit in my FWD distributor. My timing at idle is all over the place and the cure for this is the 24-1 cas disc which they did not make in the 54mm size only 50mm. I hope this GTi-R one fits I'll be giving them a call tomorrow for sure.

I did some digging and it should work read here

Well i just searched the aem forums and also their website and couldnt find anything about them having a 54mm 24-1 cas disc. Where did you get this info. Sorry if I'm being annoying man but the AEM EMS does not like the oen nissan CAS disc and runs much better and tunes much better with their 24-1 disc and I really want this to be true.

Jerry.

from a tech on the ph at AEM he said they had both now

i am using a b13 dist with the aem with no timing problems what so ever up to 8.5k just a heads up. this was confirmed on a dyno with a nice snap on timing light.

Is this free or do I have to pay for it. I mean I do have the 50mm cas that came with my aem that I could send back if that would and should in turn make it free for me.



I don't know what to tell you man you are very lucky.

Disc fits ......here is a pick of them side by side
