decided to put cos style management on my s1. got the efi manifold etc today and ordered the sensors etc just need to know that the max boost and power i can run with std cos 4x4 injectors. got a set cheap and aint got the money for the new greens just yet.

engine spec is stage three s/e 1600, big valvs, piper t2
cam, grs cooler, -31 act. std turbo (for now)
oh and does any one know where i can get a mfi/efi adaptor plate.

cheers, flax.

 

Remember that the efi pressure regulator is set for 2.5 bar only where as the cossy used 3.0 bar. Unless you up the fuel rail pressure to.0 3 bar you won't get very far.

About the adaptor plates, fyi, nobody uses them over here as it's much simpler to just grind ~4mm of the head. Some people didn't understand to grind anything away and are still getting good power and no issues.

 

i`m fitting the the cossie loom (modified), regulator, all the sensors, injectors etc. just can`t afford the greens yet thats all.

theres a chance of hittin the water jacket isn`t there. so i`d rather be safe than sorry.

 

You won't hit the water jacket but the rocker compartment instead if you go too far.
