Im in the process of building a H22a h2b car. I got myself a jdm type S motor with the atts gearbox. My question is wats the difference between the P13 block and the P5P block?

My block Code is P5P and it had the atts unit attached to it. The mid shaft plate supllied by Evolution doesn't lined up. I probably need to make a custom shaft plate.

Does any1 know the difference between the P5P block and the P13 block besides the midshaft mounting points.

The stand out thing off the top of my head would be Open Deck VS Closed Deck and Main journal size.
IIRC the TypeS block is going to have the same differences as a US SH block as well. Different mounting points here and there for ATTS equipment.
The EuroR would have been the ideal shortblock/longblock to buy...
