I own a escorth Cosworth (june 1994) EECIV T25 (latest version, with silver head)
I want to rebuild it to a previeus version with Weber-Marelli engine management And I can use some help with this.

I bought a complete 4wd-sierra engine block (green head)
Now, I have some questions;

1- The sierra cilinder head, does it fit on my EECIV engine block?
2- For the previeus versions there are hi-pressure oil pumps (or high flow kits), do they also excist for the EECIV block or does the old ones fit. (because I want a better oil pump)
3- I want to reach 350 bhp. Is this still possible with green injectors (308inj) or do I need blue ones (400inj)
4- sierra 4wd engine loom its this the same a escort T35 loom ??
5- L8 ecu better as co screww allows adjustments to the fuelling to be made if required,no co screw on p8 ecu.
6- and is 350 bhp posible whit e standard block?? (piston, crank ) ??
7- max bhp for e standard transmission

Maybe it's not good reply to you post I from my knowledge and what I read on this forum I don't see a point in the convertion. EEC IV block and head are the best. what you want is stand-alone engine managment, different IC and turbo and good mapper.
