Ordered my megasquirt now need help with injectors
 
I just ordered megasquirt for my car and I'm looking for some injectors. I havent really found anything interesting on ebay. Its either 200 bucks for used injectors that have been cleaned or 75 bucks for rusted ones. Any one know of any source where i can get some nice CLEAN injectors? preferably in 500-550cc (leaning towards 550cc) I heard about the RC injectors but how do they work, are they direct fits? I want something plug and play and I need them within the next couple days. Thanks

Get a set of injectors from an S5 turbo rx7. They are 550 cc/min, high impedance, oval top, and exactly the same height as miata injectors. They will run you around $100 for a used set + $55-60 to get them serviced (tested, cleaned, new parts, flowed).

I see no advantage in going with the RC's. Which incidentally have different connectors (square top like Ford) and a shorter tip (they don't reach as far into the motor).

I cant find either one. I never knew finding injectors would be so hard. Anyone know a source? I tried ebay but i cant find any 550cc injectors. I really dont want to go smaller then that.

Get on RX7club and contact japan2la
You can find his user in this thread i had on there.
http://www.rx7club.com/showthread.php?t=593800
He has tons of 550's and he offers then used and dirty or processed by RC.
I'll tell you right now, you can get them cleaned for atleast $40 cheaper than what he charges though. cleaninjectors.com service cost me $64 after shipping and all other fees for my RX7 550s.

cjernigan thanks for your help... i just registered there and shot him a PM. I am now awaiting a response

Ben 01-02-2007 03:42 PM

I have an extra set of the rx7 550s if you don't get them from japan2la. They are the plug n play high impedance injectors. $75 + $6 for shipping. I'll ship them directly to the injector servicing company.

PM sent Ben

jayc72 01-02-2007 04:51 PM

Ben do you have all four? I thought you only had 2?

According to the calculator in your FAQ that'll suffice ;) Thanks!

Al Hounos 01-02-2007 07:35 PM

only to about 13 psi.

Ya sure? The rx7 NON turbo injectors are 460 cc/min. Get some headroom man!

cjernigan 01-02-2007 07:48 PM

japan2la offers his 550s for $100 I think, so Ben has the better offer for sure. Keeping it in the miata community is nice as well.

miatamania 01-02-2007 08:06 PM

If he doesn't get them Ben, I want them...anybody else has a set, I'll take them :)

cjernigan 01-02-2007 08:58 PM

If you can't get Ben's put up a WTB ad on RX7club, RX7 motors use 2 of them from the factory. It's pretty easy to find people on there getting rid of a set of 4 from two different motors that they have swapped larger injectors into via a WTB ad.

Ben 01-02-2007 09:50 PM

the rex's have 4 injectors. what's a little odd is that they have 2 fuel rails (primary and secondary). each rail has a pair of injectors. think of it like a 4bbl carb. it is very common for rex owners to upgrade the secondary injectors only, and leave the primaries alone. that's why the injectors come in pairs when people upgrade. you usually only get 4 injectors from a car being parted out, and it's tough to find s5 turbo rx7s being parted.

all that being stated, I MAY have an extra pair. First right of refusal goes to JayC, second right goes to richyvrlimited.

miatamania 01-02-2007 09:50 PM

I'll have to try that then.

krayzrac3r 01-02-2007 11:01 PM

I am sending out money and they are officially sold to me... I'd rather support a miata guy that has helped me with my retarded questions ive had through this whole turbo process then a non miata owner!
