Cosworth v6 injector upgrade
Hi I am after some advice for a mate of mine with a twin turbo cosworth v6 mini !!!! Running a emerald ecu and 6 triumph throttle bodies and twin plenum chambers
He has had it rolling roaded but it's running out of fuel flow from the injectors as they are standard cosworth ones . We have seen you can fit Vauxhall vectra v6 ones but we can only find ones where the fuel rail sits on top of the injectors and not on the side as there is not room above because of the inlet manifold.
So if anyone knows what side fed injectors will fit and also how to or what needs modifying on the fuel rail to fit the better injectors then can you please let me know
Many thanks in advance

Side feed injectors, Is it a BOB v6 ?
You can fit Nissan RB25DET or SR20DET injectors. RB25's are in sets of 6.
The standard ones will give you up to about 330bhp, depends on fuel pressure.
Or you can use Subaru yellow injectors. They are said to be 550cc or 440cc depends on the year. but in sets of 4 so you wil need two sets.
Also all the above will need different injector plugs fitting. I got two subaru inlet manifolds complete with wiring to do mine.
Remember to swap the o-ring seal from the ford ones to the others.

Hi are the mustang injectors you have used a direct replacement for the standard ones fitted . It's a bob engine if that helps and do you know the part numbers for them ?

From what I can remember my mate saying I think it was 300 odd and 340 flb of torque at a limited revs of 4200 by the guy running the rolling road until he can get the higher flow injectors

Oh by the way the whole car was built from scratch by my mate on a budget in his garage over the space of 5 years and it's still running a type 9 box . As far as we know this is the only bike throttle bodied twin turbo bob engine around
