S15 HLSD

[s1390]

I'm just curious but will a S15 HLSD fit on a base model 1990 240sx? Im curious if the driveshaft would need to be the same length or different and if I could reuse my axels?

Are you talking about putting a whole S15 pumpkin into the car, Or putting an S15 HLSD into your existing pumpkin?

Driveshaft is the same, axles are different.

The S15 HLSD case is longer because the S15 uses the VSS sensor input pinion of the diff VS the transmission. But the guts swap over to a S13 or S14 case. I use a S15 HLSD in a S14 case in my S13. The axle shaft outputs are a different spline count than S13 and S14 so you need those. You can use the stock axles though. The case length is the same as a Q45 or J30 so you need an ABS driveshaft if you use the whole S15 case.

The best is swap it into a S13 case, but you need to swap your ring gear over and you need the special bolts to do this.
