Title: Current thinking on lpg injectors
Post by: Doctor Gollum on 23 March 2019, 21:10:05
As above, thinking about converting the Trolley in order to a) save some cash, and b) for the experience.

Thinking KME for the ecu and reducer/vapouriser, but unsure re choice of injector. :-\

I appreciate that the effort may not be worth the fuel saving, but it could be a good project...

Depends what you want to spend against how long you want them to last. Valtek type 30s are the ones that came with the Stag kits we used. They are cheap, do the job but one of mine went dodgy after probably 100k miles.

I notice Valtek have a couple more ranges available now, more expensive but look better.

The AC/Stag branded ones I'd rate as worse, as they couldn't easily cope with the range of fuelling required by the Omega when brand new and they aren't any more durable.

Other end of the spectrum are Keihin, BRC, etc. which are much better but probably not worth the high prices unless you are putting them on a low mileage car that you expect to be around for many years, IMHO.

Check what types are supported by your ECU as they all have subtly different drive requirements and accurate calibration (and sometimes not letting the smoke out!) depends on having the right profile.

Would it be a reasonable presumption that a front end kit would have appropriate injectors?

Have seen a choice of Valtek 30/35ohm iirc, and given the price, sub £80 for a rail of 4, a 100k mile service life is pretty reasonable. ;)

That said, Hana 2002 Gold can be had for sub £90...

Type 30 with 3 ohm coils are the ones I had. There are now type 32 and 34 which look interesting but no experience of either.

I had no issue with the Valteks on the MV6 (and the superior Motronic ECU meant none of that horrid lag intrinsic to the later Motronics running Stag).  So much so, I'm considering taking off the (crap from day 1) Motogas branded ones (AC rebadge I suspect), and putting on our spare 90k mile Valeks on TBE.

I know Gixer has used Hana ones for a few years, but think he is starting to get issues with them.  Though he does cover some miles.

I have a couple of tanks here to donate if you want one.  They would need testing to be LPGA compliant but they are free :y

Ta :y will bear in mind.

Trolley only has little wheels, so need to get the tape measure out...
