Author Topic: Engine Swap! 1997 standard to 2000 Interstate. Any "gotchas"?  (Read 1126 times)

I just bought an engine pulled from a 2000 IS and am going to slap it on my 97 standard.
As far as I can see, it's a 1 for 1 swap: just unbolt the existing engine and throw the new one in.

I've got new compressible washers for the transmission line. But don't think I'll need anything else but new fluids.
Am I missing anything?
Are there any possible differences I didn't think of?

I'm hoping to get the swap done in one day, and spend the next day connecting all the hoses, cables, etc...

Thanks

Using the Interstate ICM ? Washers for transmission line ?

Wasn't planning on using anything else from the interstate. Only the engine itself.
Do I need the ICM from the IS? The physical specs are the same, right?
(timing, bore, stroke, etc...)

I already have the washers for the transmission, and the exhaust since they're both compressible.
Thanks

I think Lyonardo is talking about the clutch slave banjo bolt washers.

Meathead, yep.
Those brass washers for the banjo bolt.
Thanks

Hopefully somebody more knowledgeable about it than I will chime in. But, it is my understanding the timing advance settings are different on the Interstate and Standard ICM's.

The standard ICM will work just fine. The only difference is the IS ICM has 2 more degrees of advance in the mid range. You probably won't feel the difference.

The IS ICM does have more spark advance than the standard/tourer and you will feel the difference.  If you have the IS ICM use it.  But either will work just fine.

The carb slide springs are different too. The IS springs have less resistance to allow the slides to open quicker.

OK, I'm confident I have everything on hand to to get this job done.
I might just grab an Interstate ICM when I get a chance too.
Thanks

Did I buy IS springs for my Standard for nothing?? ($$). I haven't installed them yet, but I thought they would improve the carbs on the Standard or I read something like that.

Last year I put the Interstate box in my Standard and I can feel a small but noticeable improvement in highway roll-on. I`m keeping it.
 Don`t want to put the springs in as well, this thing uses enough fuel as it is!!

The IS springs will make your carbs more responsive.

a couple of the I/S engine mounts are rubber, all std/tourer engine mounts are solid.
