i'v brought cossie management that has efi inlet manifold but i want to use my s1 plenum what do i need and were can i get it from.gary how is doing management for me can do the necessary mods but if i can buy the parts from somewhere it will save him some time and grief

 

I modified the bore where the injector sits then modified the fuel rail and has some mounts welded on so that it would bolt down and seal on the rubber seals.

 

same as above

i think the s1 inlet is the better option of the 2

for further improvements

 

Can you not use the efi version from a FRST? that fits cossie bosch injectors & has a suitable fuel rail , just match the port to the head (think efi head has injector cutout on port in head) & sort the Throttle body.

 

thanks guy`s looks like the frst opition is the better route
