What is the main differences?

I know about the coil and management, but what else?
The oilpump is a lot cheeper? why?
Anything else?

 

block has better oil squirts...on eecv

 

I asume that this is the inserts from the oilpump?







What are the differences in the oilpumps???

 

the oil squirts spray onto the bottom of the pistons to keep them cool..essential at high boost/high RPM



have no idea about the pumps mate?
i think the eecv block is slighty stronger thana regular 200 block too fue to smaller core plugs? could be wrong tho.

 

Isen`t the std escos 93 spray ones good enough???

The block i have heard of, but not sure either

 

I run an YBP engine.

The YBP block uses oiljets mounted directly onto the block and because of this a regular pinto oilpump can be used. Or in my case I used an uprated high capacity/high pressure pump. This will fit with a little modification. Still alot cheaper than a regular cosworth oilpump.

The last t25 engines has m6 bolts on the cam bearing caps and are not suited for uprated valvesprings and/or wild cams.

It has bigger waterchannels in the head so not ideal for your 700+bhp enginebuild because the port size is limited by this. Not a real problem on a more "normal" 5-600bhp engine tho.

It also has new and stronger flushmounted valveguides to improve flow.
Bigger plenum elbow and throttlebody to.

 

I think windage tray fitted to eec4 but not p8 models?

 

What exactly does a windage tray do?

 

Stops the crank from picking up all the oil in the sump and throwing it everywhere at high rpm.....

 

Ahh right, thanks Mike

 

It´s also pretty thick and stiff.
I had to modify it to make the bigger oilpump fit, and found it very hard to cut into. So I believe it serves a purpose as a "girder light" supporting the main caps a little.
