First of all Tom, i'd say have a close look at your engine, i suspect the injectors are actually in the manifold on yours - earlier cars i believe had the injectors in the head.
If yours are in the manifold as i suspect, all you need do is change the manifold to the new engine. I wouldn't worry too much about uprating the injectors yet, if you set the idle mixture correctly on the fuel distributor, there's every chance it will be right for the rest of the rev range, despite the increased capacity. If you find you need more fuel then perhaps those from a B230E or a B200ET will be right. I haven't been able to find any flow rates for any of them either so can't really give any better pointers but you'll be getting it rolling road tuned anyway and if they know what they're doing with K-Jet, they can alter the control pressure to increase the fueling if necessary. The injectors from a B280E WON'T be suitable as they are for the LH-Jetronic. I'm guessing you meant the B28E which had K-Jet BUT don't forget this was a 6 cylinder engine pushing out about 150bhp (on a good day!) so 25bhp per cylinder. That would give the amazing output of about 100bhp from your power "upgrade"!!!!! Also don't be fooled by Bosch part numbers, they don't work that way. There's no real logic to how they've been assigned so i can only work out they were done as and when new injectors became necessary for certain engines and others couldn't be used.

Just going to piggyback this- so if I'm looking at replacing the stock yellow injectors on a B200f, what bosch ones should I drop in that have the better mist pattern? Would really appreciate a link. If it makes any difference, I have changed the stock M cam to a V cam...

You'll find they are quite a common injector, i bought 6 from a Y32 engined Vauxhall Omega : Other Vauxhalls, Fords and similar use them too so you should be able to find a set of four on ebay fairly cheaply.

Would probably be better starting a new thread rather than confusing a thread on electronic injectors |
