I'm putting a 98 S3 motor into my 96 S2 this week. Aside from the motor, I'd also like to put on the S3's exhaust, wheels and a cast swing arm. Does anyone know if I'll run into a problem with this swap? I'm not sure if the S2 will accept these parts. Thanks Steve Ford | ||

I belive all of those should be a direct swap however you may need the s3's rear shock to go with that swing arm though i could be wrong. | ||

I believe you're going to have clearance issues with the swingarm, and with the header. I don't believe they'll fit, without work. The engine should bolt right up, though. | ||

It should all bolt up unless the 98 had the header that goes under frame vs over like the S-2. Swingarm will bolt up but unless you are lightweight and do not do 2 up the swingarm will hit rear frame bars when you hit a big bump. | ||

As in swing arm rubbing on frame? | ||

The exhaust will be fine if it's a 98. '99 is when the exhaust started running under the frame and crossed. The stock swingarm mount can be shaved to accept the aluminum swingarm, of use the mount that came with it. I thought '99 was the first year of the cast swingarm though... | ||

mother thing to note, if you use the aluminum swingarm you'll either have to use a Nissen rear caliper or build/find a special mount for the stock brembo IIRC. | ||

I think I'll keep the box swing arm, thanks for you input. Got the motor out and the frame all down to bare bits on the S3 - busy day. Had to improvise a bit with cinder blocks for an engine stand and an 8x16 hex head and a bunch of nuts and washers for an isolator removal tool. | ||

I was told that the brembo caliper would work with a cast swingarm. | ||

So far, so good. You do have to use the later (98 onwards) spacers with the later wheels yet use the earlier axles with the steel swing arm and WP S2 fork. | ||

It's getting there, slow but sure. Does anyone know if the VOES and voltage regulator changed between the 96 S2 and 98 S3? I have lots of shop manuals but no parts manuals. | ||

dunno, but I pulled the VR off my '03 sportster when the one on my S2 went bad. the plug was different so I spliced the old plug onto the new VR and it worked fine. |
