kr head on pb management?

[gazareth]

hey guys. does anyone know if the fuel rail and injectors of the pb engine could be made to work on the kr engine?

[Gambit]

nope it wont work

yeah I was giving it some thought last night and I realised that the injector spacing on the rail is different and the injector spray pattern is wrong (but I think rover 1.6 16v ones would work). but when you consider the rev limiter on the 8v management been kinda low it aint really worth it.

20vt fuel rail is right spaceing but dosent fit rund the manifold.  abf manifld and rail would work,  aftermarket rail will work.

injector spray pattern is ok just need to swap injector seats for digifant ones.

it will run and work but wouldn't bother with digi 2,  fitting digi 1 of a g60 used to be the trick when applying boost to 16vs

I would have thought the digi injector spray pattern would be wrong for the 16v as its single cone instead of split. would it not just hit the port divider in the head? what about the fuel rail of an 8v crossflow head? do they have evenly spaced injectors?

[danny_p]

none of that really matters,    a fuel injectors sole pourpose in life is to mist specific quantities  fuel  and squirt it into the inlet somewhere as long as it dose that all is good.  the finer the mist the better but thats it really

the jet of fuel won't actualy get to the port devider when that cyl is on intake stroke air speed will drag it round and straight past it.    on the other 3 injection events with digi  the intake valves are closed so going to hit something anyway dosnet really matter what it is stilll get sucked into the cyl pritty damb sharpish

[gazareth]

yeah the digi injectors may work but its far from ideal. after all the digifant is simultaneous injection. not sequential like later designs so the closer to the valve you get the spray. the better.

and k jet injectors that were origanly in the 16v head were contiunusly drizzeling.

and there were digifant batch ingection 16v's  g60 16v was done that way

hey you were right about injectors. pulled 1 out of a rover 16v the other day and it was a single cone nozzle design. I know some had a split spray cone but I guess it aint all of them.
