Hello,

Im about to drill and tap my charge carrier to fit the pressure switch and injector for my Erl fifth injector set up.

The one on the right is what came with the kit, the on on the left is a spare fifth injector I have from a old manifold.

My question is, can i happily use the spare fifth injector in place of the beige and holder, as I can get it seated better and it looks tidier.

Can I ask why you have gone this route instead of a full EFI setup? It's a fair bit of work and cost for what's only a half job IMO.
But yes you can use almost any suitably sized injector that you want.

 

I have seen and setup both style of injectors on the MF2 drivers. Personally I would use the EFi injector due to the flow pattern it should supply. However that will be the next question. Surely your not going to aim the injector at the opposite side of the charge carrier. It will end up in a pool of fuel just before the throttle body.

ideally needs to be placed on the sweeping bend flowing towards the throttle body.

 

I really wanted to stick with what was meant to be there so to speak, and im a sucker for old school. Im not after mega power, just want a nice clean weekend car with around 200bhp.

Besides, everybody is going modern (reliable?), so thought id break from the norm

 

I know it needs to be angled, and Im bowing to the gurus more knowledgable than me on this. Im still brain storming atm, so just thought id ask the question. Is the injector in the holder from a FRST or Cosworth?

 

neither with a fuel fitting like that. whats the part number. Better pics of top of injector.

 

I personally wouldn't use an old 80's/90's injector at all, go with something new for better atomisation, certainly as it's being injected a long way before the ports.

 

These are the numbers on the parts. Im going to purchase a new one for piece of mind I think. What would you guys reccommend?, links etc?

Thank you for the advice chaps, very grateful.

 

Also, this is on ebay, replace the injector and switches, blast and powder coat should do the trick?

 

I understand everything you said but still see it a waste of money effort and time.

The MFi system shouldn't really be pushed to the point you would need the mf2 now days anyway.
Personally id run a boost level that the system can fuel without needing extra injectors.

 

On that ebay inlet, has someone just clamped fuel hose round the o-ring on the top of the injector? Surely that cant be sensible, it's a push-in fitting for a fuel rail

 

none of it is sensible he is trying to make the most of it. So all we can do is help him best we can if thats the way he must go. its his car all we can do is support him. Whatever our views are.
