Are there any Lucas injector alternatives ?

[anonymous-user]

Hello,
I'm not 100% sure this is the right TVR forum but I'll give it a go anyway. I'm building a Westfield with a 4.2 Range Rover engine and need to source some higher flowing injectors. I'm using a modified hotwire manifold and fuel rail so ideally I'm looking for some 24lb (or so) injectors that will fit straight in - high impedence too please.
I've seen plenty of Bosch style injectors (like these: http://www.fiveomotorsport.com/domestic-high-perfo... that could be made to fit but they don't appear to be a straight swap due to the o-rings and retaining clip groove being in slightly different places.
I'm sure (hope) some TVR owners must have found some.
thanks
Mike

I swapped my lucas originals for bosch alternatives to do just what your trying to achieve,and really regretted it to be honest.I lost a huge amount of top end horsepower,as did a friend who also did exactly the same swap.If you havent uprated your fuel pressure yet then i would definately consider it as a viable alternative to different injectors.The Lucas originals will take 3.0bar very reliably i found,and this is enough to get you 340ish bhp.The bosch injectors did give ever so slightly better bottom end torque though,which helps a little if you have a lary cam,but i found the top end loss far more significant.
Webber make a nice remote 3.0bar pressure regulator,but i'm sure a bit of research might find alternatives.The end of rail regulator was made for a few different applications and ive often wondered if one of them would fit the bill,perhaps with vac pipe disconnected?

Have a read of this.. it lists info regarding Chev LS1 injectors

OK, my head hurts now.

I've got some Lucas injectors that I had cleaned a few years ago but never got them out of the wrapping. It turns out they replaced one totally. But it's not the same !!!! So that leaves me with 7 matching, cleaned injectors and one brand new that has a different number.

I think it's best for me to start from scratch then. The only requirements are that they fit in a hotwire manifold with the standard fuel rail.

I'm going to try to digest that LS injector info. I'm sure I've seen people have to 'file' that style down a little to get them to seat correctly - I mean take a little of the width at the lower end just above the bottom o-ring.

I'll probably be back later.

thanks
