^ very interesting thread also.. from teamintegra.com

so can someone tell me again that i'm using the wrong waterpump.... proof is there.. so that pretty much covers my waterpump RIGHT????

but what i found out is that.. the waterpump that was originally on the block was a non-vtec waterpump on a vtec block..

copied from TI:

Discussion- you can't really say one is better than the other since they were designed for different goals. I can honestly say the NON-VTEC pump is more efficient than the VTEC pump for several reasons. It moves over 30% more water per engine rotation!

Reason #1- greater surface area on the impellers. Both pumps have 7 blades or "Impellers" pushing the water through the pump. the non VTEC surface area is approximately 0.291 inch square while the VTEC pump is 0.258 inch square. This makes the NON-VTEC pump move 13% (113%) more water per revolution.


so i guess i'ma slapp back the 19T back on then..?
