I may need another set and was wondering is there anybody out there who can help ????

For JB? or other?

Flow rate? Brand ? How many? High or low impedance? Need some more details buddy

Is it for your twincam to fix your problem you posted on 4gtuner?

Yes Shannon I posted it to see if there were any suggestons forthcoming that might lead to a fix but no luck so far . 800 cc sards
Still can't find the cause of the miss despite testing the coil harness, new no 4 coil changeing to a complete different coils( VR4 )new plugs ,leads comp test all within 5 psi hot or cold so about to get injectors tested This is very fustrating and pissing me right off :x :x

I use these on my 4G63. 1000cc gives me plenty of size for E85 and they're half the price of Sard or other big-brands.

It's not cheap-shit either, they're just re-badged Denso's.

I got them landed here in Oz for under AUD$420, that's pretty good.

Good info Lummy, :beer

i use and recommend siemens VDO injectors, i have heard baaaaaaad things about sard injectors TBH.

the rc's i'm pretty sure are modded (bored with a parger pintle) denso's.

My gem has hks 1000cc's but that was before i found out about the siemens ones, they are a 4 nozzle type, very stable at low openings but still squirt like hell when needed. and they're not much more than $120 each, available in a number of sizes and configs.

Dave,

I had Siemens injectors in the DASH motor on recommendation from the tuner (MRC). Worked a treat and never had any issues with them. Nice spray pattern and good control over them even with an older version Haltech controlling them so I back you up there on Siemens.

Currently have SARD's in the twin cam. Will see how they go and if they play up will switch to a Siemens injector. So far though the SARD's seem OK, no complaints (yet). :beer

The problem has been narrowed down to wireing and or computer

We were barking up the wrong tree :x All loom wireing tested ok the umpteenth time Haltec came back ok No error codes in fuel & ign maps so Lee hooked up a trin pot and took fuel out of cyls 1&4 and IT RAN ON ALL 4 but started to play silly buggers again on the way home.New 780 cc Seimans on the way so fingers xx when they go in it's the end of my problems for quite some time

The majority of cars I work on use Siemens injectors, very very very reliable!

Rad,, have U used a thermal Temp Gun on the Exhaust manifold to see which is running hot/cold, of course it has to be on Dyno & on Boost. Rad what Ignitor are U using & what Coil Charge & discharge time are U using? I have a feeling the Coil charge time is to small, try 3.8Ms for charge & 0.8Ms Discharge time.
