2005 NA Elise fuel injectors... a good replacement?

I have a stock NA 2005 Lotus Elise, T4 ECU. Having some issues that could be related to fuel injectors so I shipped them out for testing. In case they are horked I started to look at sourcing replacements but only found them for $150ea. There has to be a better source given that we share an engine....

Has anyone used or had experience with the brown or yellow Toyota injectors?

2005 Lotus Elise OEM injectors are gray, denso 23250-22070:
Part No. TOY-23250-22070
12.1 ohms, ~330 cc, 32 LB/hr

There are 2ZZ-GE injectors that are more readily available and much cheaper. Has anyone used these?:
Part No. TOY-23209-22030
13.9 ohms, ~330 cc, 31.2 LB/hr

Will these do the job w/o causing problems? Does ~2 Ohms really make a difference? Opinions on QRP parts from MWR?

These injectors would be an upgrade from what you have and they may be larger than you need, but they are a later generation and might provide somewhat better performance for considerably less money than $150/ea. If you wanted to upgrade your engine in the future these would be a good way to go. If you want to stay with stock levels BOE can probably help with the same series injectors with a lower flow.

If you put larger injectors in, you need a tune to compensate. So those won't work. Also BoE doesn't sell anything for OEM. I suppose I get it given the market demand...

Any other sources / experience w/ OEM or off brand injectors?

Although BOE stocks only the 550cc injectors this same series is available in other flow rates from 315cc to over 1000cc. Price is $70/injector. If you know the flow rate of the injectors you are trying to replace these are probably a good option. A custom tune is probably the ultimate way to go, but the ECU can "learn" within certain limits so if you can get reasonably close without going too much over the tune is probably not necessary.

There's no reason, what so ever, to change the stock injectors to anything else, all else equal. If you fail a stocker (which is up there with lightning strikes in probability), then replace with the same part.

Further, if you do change away, you will only incur heartache.

Take due notice thereof and govern yourself accordingly.

Cheers

I went with Scion xB injectors two years ago and have not had an issue, they were a direct replacement at 330 cc. I should have a set of Lotus injectors that were professionally cleaned and balanced checked that I could sell, just have to look for them.
