I have read many people saying you can find JCW injecotrs for $250 here and after 4 months of waiting and looking no luck. I have read the article from Mike-Myes about 480CC vs his 550CC injectors. My ? is do you think it would be a problem running 380CC or 400CC from FiveO ? My tuner says that 550 way to big for what I have done so 400CC would be just right. Now I am looking at $230 (fiveO) vs $550 (JCW) So is their anyone running these (Fiveo) injectors in their car? If so Tuned or untuned? Thanks again

 

I was in your position a while back but after months of waiting, I did end up with JCW injectors so don't give your hopes up yet.

If i remember correctly, the FiveO injectors are either re-drilled or have different spraying patterns than OEM. So I would advice you against it.

If I were you, I would either wait for JCW to come up on the marketplace or just bite the bullet and buy them new.

However, if you really don't want to spend that much money on a set of injectors, I would go with Helix 380cc. Because they advertise that they have the exact same spraying pattern as the OEM (dual cone spray pattern I think) and they are on sale for $310 or something. And they are Bosch, too.

And injectors are pretty much useless unless you have +19% pulley or a tune. 15% pulley with stock injector runs about 92% cycle at WOT. and when anything larger than stock injectors are installed, ECU would simply adapt and reduce the duty cycle. In fact, when I put in JCW injectors, my mpg on the display went up 3, when in reality it didn't.

But if you plan on going all-out, bigger injectors like 550 might fit your bill.

hope it helped.

Good advise....if you need to save a few $$, get the ones from helix or RMW....injectors are not a place to skimp on quality...five-oh's are redrilled injectors from overseas.....from the color coding, from very small flow rates...there are a few articles/threads around about them...they are not the right flow pattern, may not be flow matched, and redrilled injectors usually exibit poor atmosization....all very bad things for any motor....never mind a high performance modded motor. $300 is closer IMO for the price of jcw's too...got mine new, in the box plus shipping for 300...but lightly used will pop up for similar $$.
As for size...depends...you should really plan on getting a tune, even with JCW's....but they can be run right away...the others will need to be tuned ASAP when installed...like same day, most likely the same shop.
IMO, the JCW are fine for pulleys, cai, and cat back...about 210 hp, just like the jcw 210 cars....but if you plan on doing headders, headwork, etc...than bigger will be needed down the road...which is the reason why so many used sets of jcw's are around.

 

That's right: ours are not re-drilled, and they have the correct dual-cone pattern for MCS heads. They perform exactly as the JCW ones. We are running a special on them for $319 for the set. We'll have some at the Dragon if anyone wants to check them out.

 

So helix what are dragon ones? What size and cost? Thanks
