Cosworth injector,s
hi lads as some of you might be aware I'm planning on building a 500bhp motor yb for my focos . And it's come into my mind of wot
injectors are out there these days to run this power . Iv got black 55 siemens injectors at the mo but they will be to small when it comes to the time to run the motor up . So dose any one no wots out there to use these days ???

'keeping costs down' is risky at that power - you might be better if you sell the L8 and get a modern ecu.
far greater options for injectors
easily run Toyota yaris COPs
engine safety features e.g. fuel pressure v boost monitoring
you can easily adjust the maps
etc

There are lots of modern injectors available but none of them will run with an L8 ECU as they need to be low impedance. I guess that is why a lot of aftermarket ECUs get installed.

most after market ecu's are aimed at modern (high imp) injectors. modern ecu's which are able to support low impedance injectors are generally aimed at supportting legacy injectors or very large injectors e.g. 1600cc upwards (which tend to still be low impedance) . you aren't trying to support legacy injectors but you *are* trying to support a legacy ecu!
by the time you add wasted spark board and leads and all that stuff to the l8 you are cobbling it together and it costs about the same as aftermarket but with less features.

I don't see much point spending Ł1000 plus on an ecu and mapping if the l8 works !!! Same with coil packs, the distributor has worked perfect for 30 years and still does today. The money can be spent on better things !!

well the distibutor system is not suitable for 30 psi boost for 500hp and to make the L8 run wasted spark costs Ł300 in bits and pieces and you still have a coil pack set up with HT leads which isn't as good as COPs. most modern ecu's can run COP's such as yaris ones directly and as regards the cost of mapping - you have that irrespective of what ecu you have. no brainer if you ask me at that power level.

Anyone that has been in my car are always suprised at how hard it goes and it may not be bang up to date but it puts a big smile on my face!!!

My car is the same mate very old school with a t4, ported head, bd15 inlet, l6 and greys. Still running on the distributor, never misses a beat and gets its head kicked in !!! I love it tho bought a l8 and trying to get my hands on a set off 83lb Siemens but not having much luck.

many ecu's designed to run low impedance injectors can run high impedance injectors without problem. has anyone tried this with L8?

They have in stock a Lucas low impedance injector which they say is the modern replacement for the Siemens 890cc injector old part number FI11405 New at $69.95 each .Lucas OID142B is the part number. Go on their site and you can have a look. Seems to me they will do the same job.
The link is in grcossies post above. Hope this helps the people who are looking for the injectors.

When I did the last power upgrade on my 2wd Saff I fitted an L8 ECU with a wasted spark baby board, new engine, fans and Bosche 044 wiring looms, wasted spark ignition, Siemens 890cc injectors, T38 turbo with billet compressor and A&S Hart style inlet.Had a group A ported and polished head, BD10& BD12 cams, 200 wire rung block ,low comp pocketed pistons already. Running 2 bar of boost with a custom live mapped chip and it goes like a rocket with no problems so far.

Mark Shead put 1000cc injectors in mine. I am on Vipec though with COP

My understanding of the old L6/L8 is that you can not change the duty cycle of the injector as you can with modern ecu's. Which I thought meant that when you put 1000cc injectors on the older management, at idle and until you're on Boost you get heavy overfuelling. The new managements allow you to change the amount of fuel an injector delivers throughout the rev range giving you a much better burn. I'm sure someone will correct me if I've got this wrong!
