I have an B18C1 engine and have stumbled across a very cheap AEM Pulley Kit for the Intera Type-R.
I know that AEM has a kit for the GSR aswell but the question I have is, what is the difference between those kits?
Anyone know?

Is it just different lenghts on the belts provided or is it different in the wheel tooth profiles?
Can I fit a ITR kit to a GSR engine and just buy new belts?

 

The pulleys are interchangeable. The alternator belt is of a different length, but the power steering pulley should be the same. If not, it's not hard to resize another belt.

 

So it´s just a difference in the belts between those models?
And not any difference between the wheels`?

 

Exactly. I run an ITR crank pulley with a GS-R AEM PS pulley/belt and stock alternator pulley.

 

if I get your right...
You have a ITR in which you use an AEM PS pulley/belt ment for a GSR.
And you use stock alternator...

You have therefor only changed your PS pulley and uses the belt for an GSR on your ITR?

I know i´m slow when it comes to engines but sometimes i´m dumber then ever...

 

I've got a GS-R (B18C1 block) and accessories. I just happened to install an ITR crankshaft pulley on it. The ITR crank pulley has a slightly smaller diameter AC and alternator drive. The PS drive is same size as the GS-R's crank pulley.

You can use the AEM's Bando belt for the power steering, but the alternator belt is probably of a different size b/w the GS-R and ITR AEM pulley kits.
