Thanks for the info. I wouldn't be surprised if the beams setup taper and restrict as much as the standard 205 pump. There would be no reason why i would hurt the oem pump by porting the cover and sump, if anything it would give it an easier life. Did some googling myself. Standard pump will provide enough pressure. If one comes up at the right price I will upgrade and mire than likely still modify to remove restrictions. For the time being I will stick to the stock pump as I'm only revving to 7500rpm maximum. Depends where the power rolls over. Found this on imoc.co.uk
http://www.imoc.co.uk/forums/viewtopic.php?p=1480627Main reason I am using an electric water pump is that it will run after the engine is switched off and to feed coolant from the four core plugs at the front (exhaust side) of the engine. Using a 5s block as overall its a stronger block but every little helps to keep from shocking the engine to cold-er water bursts to one side of the engine when the thermostat opens. Just trying something different. If it works all the better. If not back to what does work

Piston at TDC with 86mm crank.
Ordering rods tommorrow. Ordered flywheel today from TTV. Should be lighter than 4kg but will see.
Oh and thinking of selling the Blitz K3T turbo and Audi S2 wastegate (both refurbed and good to go, needs custom manifold) PM if interested. I'm after something smaller.
Thanks
