RB Sump Bolt Sizes

Hey guys,

I've been lurking about on here for about a year now, but have always managed to find an answer, so ive never signed up! Now I am stumped:

does anyone know the bolt sizes to secure a RWD sump onto an RB26?

Ive ordered a McKinney motorsports sump to suit an RB26 conversion into my 260Z, but the sump uses a different bolt pattern to my original sump, and I don't have a tap and die set to check what size the bolts are

I was wondering if anyone here knew? I'm hoping to test fit the sump on the stand to check for flatness, etc before I continue

 

cheers in advance,

Jamie

I believe rb25 is m6 x1, and that's an extremely common size, so...that'd be my guess....based on never having touched an rb26 in my life.

Spot on... just got it sorted now.

the original sump for the RB26 uses different bolts, the ones on the outside in the picture. I assume to support the extra weight of the diff...

thankyou very much!

if anyone's after an RB26 sump with front diff let me know, it's just lying around now...
