Hi folks. I am looking to buy a kaaz 1.5 way diff for my jdm 98' s14a but am unsure what part number I would need as there are a few. My car already has an s15 helical diff installed and I am unsure whether I need a kaaz for an s14 or s15 as the model number appears to vary depending on the car and I'm not sure if the casing I have is an s14 with s15 diff or an s15 casing with s15 diff. According to the driftworks part number list a 1.5 way for an s14 is SBN2745 and for an s15 is SBN2610. Anybody able to give me any advice on what I need or his to identify what I have? I would assume it's the s15 SBN2610 part but unsure. Thanks.
OK I just wasn't sure incase it make any difference depending on if s15 has different half shafts and length nose bit that bolts to the prop and if being abs or not would make a difference or the crown as I'm not particularly clued up that's Alot of conflicting info out there the casings are and are not interchangeable. Il go with the one recommended s15 helical then.
