TECH: Switching to Multi Groove pulleys
Posted: Mon Apr 30, 2007 8:28 pm
Just though i might share some findings since we get repeating threads in regards to superchargers, power steering, alternators, air con compressor pumps etc etc
I am gathering the last few bits for a bolt-in engine build and felt i needed to share my findings
To start with the easiest way to not touch anything and add a multigroove acc is to buy a billet v/multigroove crank pulley
They are available from spidertrax for US$55

For alternators or people who just want to go the whole shiz to increase strength and reliability (and might be perharps cheaper)
Crank pulleys are best sourced from a late model 1lt swift as they are 4 bolts matching the sierra.
i got one for $15, my gti crank pulley one cost me $45 and i had being looking for a long time for someone selling it seperately (and i imagine the vitaras would be the same.)
Water pump pulley?
late carbed or efi Vitara or Daihatsu 16v 1.3L
By chance i stumbled on a the daihatsu pulley at pick'n'payless today, amazingly it's the same bolt spacing, same diameter, same number of grooves (4 but some makes use 3 or 6)
the only difference is that the daihatsu pulley center protrudes an extra 2.7mm. Not a biggy as the bolts that hold this pulley onto the engine come with tiny washers that a 1.34mm thick, put two of these washers on each bolt as a spacer inbetween the pulley and the pump and it should sit in the right spot.
The pulley cost me $10, i bought it just to see how close it was to the vitara pulley i already had so i'm not going to use it, probably take it back and swap it for some other stuff i need unless someone wants it for $10?
I'll take pictures of it and clean up this post later maybe something for the sierra bible. Bar the alternator you could do the swap for as little as $25
