Pully dowel holes

[mmt 15]

Hi guys,

are there any differences between the pullies from a mi16 2.0 and the GTI6 engines? Are the dowel holes in the same place? 

 

Thanks.

It's not the same design, much like the whole head in fact.

pin holes are in the same 70 degree from base line of the block, but its a 2 piece pulley on the xu9/10j4 and one piece on anything later or 8v.

Err, hate to contradict you , but I think it is the the other way around. The XU9/10j4 pullies are all one piece items, with slightly different offsets depending upon the number stamped on them (2/3/4) The later xu10j4rs engine with the different head had the two  piece vernier style pullies . I have no idea if the dowel holes line up between the two.

Errr it is the lower pulley with a hole for a dowel to align into the block.

Ah. Mia culpa Mei. I thought the reference was to cam pullies . Crank pulley. Dunno .

On the xu9 pulleys are 42 teeth, 360° divided by 42 is 8.57° per tooth, "2" is 114° and "4" was 106° so to get as close as poss without verniers you could get away with 105.43° by moving one tooth....

Thanks. 
I Will use the GTI6  crank pulley on the GTI6 engine and the mi16 one on the mi16 engine :-)
