I can confirm the stock pulley for an Atom 2 300 is 3.4"

just go for a smaller one haha.

we are doing a jackson and charger cooler install in 4 weeks time. ill keep you updated on progress.

A few people on this forum state the pulley for the Atom 2 300 is the 3.2".

Peter measured his and it was the 3.2"

Factory got back to me and stated it was 3.4"

The ids are a lot better. I have a set of 1000cc on the car now.

And I have a set of 750 in the garage witch have done 1000 miles

Many people including me had make bad experience with the RC injektors.
They often get blocked and have no good spray pattern.
I would recommend Injector Dynamics.You get them at CPL too.A few bucks more but they are much better and resistent against E85. I have a set RC-650 here.Flow only 350-400cc AFTER proffesionel cleaning. Trust me you won't get lean at WOT in supercharged application.

Nice one. Cheers mate

SL4 550. CPL have them in stock @ £309 (inc VAT) for a set of 4 (http://www.cplracing.co.uk/products.php?productid=154). Can't recall the factory price but I do recall being shocked at how much more the factory were charging

Spoke to the factory. They stated original injectors on the AA2 300 are the RC 550cc ones.

Forgot to ask when I spoke to the factory but I'm looking for the 550cc injectors but there are different ones.

Smokin do you remember if your ones were like :

SL4 550 or SL9 550 ???

Mine had RC fitted when I got it, and the dismal report from the firm that cleaned them suggested to me they were original factory fitted, but as I didn't buy it new I can't confirm for sure

Hi Guys,

Stock injectors are 550cc
The pulley is 3.2" (I believe) but I have seen 3.4" available
If I'm right about the pulley then the charger is 8/9 psi

Is the brand for the injectors 'RC' ?

As has been mentioned the stock injectors are 310.  The 430 injectors from the Acura RDX(US spec) are a direct swap--you can use connector clips or pigtails.  Apparently, the spray pattern is a bit better and you can get an extra 5hp out of the swap.

I broke two pintles when I changed my intake manifold.  Since the pintles are not available separately; i upgraded injectors at the same time.  I recommend the clips as it is a plug and play option.

Cool. Again thanks for the replies

OE K20a (applys also to the k20z) injectors are 310cc
