RC Engineering 320CC Fuel Injectors?

Postby Aoki Magic Pants » Thu 12.07.2018, 13:49

Hello!

I suspect that I need new fuel injectors due to lack of power over about 4k RPM, hot starting issues, and what sounds like cylinders misfiring on hot idle. I'm running on stock turbo with an Everest chip, from what I can gather these are the correct injectors for a UK S2 turbo:

https://www.ebay.co.uk/itm/RC-Engineering-Peak-Hold-320CC-30LB-Fuel-Injector-PL2-0320-1/382314219212?hash=item5903b406cc:g:o84AAOSwy0JaOU9X

There doesn't seem to be many options now when it comes to injectors, and the Delph injectors on eBay seem to divide opinion. Does anybody have experience with these injectors, and can I do any better for this price?

Cheers,

Phil.

Injectors are a bit of a minefield.
Even Rock Auto show the same part for both NA & SE, but the NAs ones do not work.
Rock also show another for the SE: Intermotor FJ559. I have these & apart from a slightly lumpy idle when cold, they work ok. Nick Walker fitted them to his Elan but it did not seem to like them very much, causing lumpy idle & a very minor misfire

I replaced my injectors because 1 packed up completely, leaving the car struggling on 2 cylinders (they fire in pairs & 1 can knock its pair out) but if you are just experiencing poor running, then why not try getting yours cleaned?

Are you talking about the Intermotor FJ559, or the RC Engineering injectors here?

I did/am considering just getting them cleaned, but figured it might be best to just replace them to reduce the chance of the electric aspect of the injectors failing in the future, assuming that it's not an electrical fault that is causing this issue in the first place.

Intermotors. I have not tried the RC Engineering ones so can't confirm if they will work or not.

I have used the GM ones listed in the US on eBay:

https://www.ebay.com/itm/Set-of-4-BRAND ... 1438.l2649

They work fine and idle fine. $169.00 for a set of 4 (four) and $24.91 postage. Two sets left.

The Rock Auto part is "STANDARD MOTOR PRODUCTS" FJ559 and $106.79 each is stupid

The price for RC Engineering injectors PL2-0320 is also way too much for the injectors.

I would also suggest that you verify the waste-gate isn't frozen or hard to move as it will give similar symptoms: http://wikilec.com/view/Wastegate

Sounds like it is slightly lean, you need to reset the ECU and adjust the CO after fitting new injectors.

:agree: If the injector packs up electrically it needs replacing, otherwise clean them - £50 for all 4 by Scholar in Suffolk, near me..forum.lotuselancentral.com/viewtopic.php?f=38&t=24707&p=311386&hilit=+scholar#p311386, otherwise I'm sure you can find a local service for a comparable price.

I've got RC PL2-320 (Bosch style top) in mine currently and they work perfectly.

Got them from https://www.fuelperformance.co.uk/

And it was £300 inc delivery and VAT for a set of 4. Be aware if you're ordering from the US you may get hit with import duty so factor that in to your price. Fuel Performance don't list them on their site but Duane did an order for them from RC directly (meaning he dealt with the import duties).
