Am I doing this right the first time?

$300 for the best tech PNP cleaned and matched injectors. Cheapest? Not quite. Right way to do it? Yes.

You can get new rx8 injectors for like ~180. I got mine for 80 and paid 100 for flow cleaning.
I'm running GT500 injectors, and just switched in the last month so I do know what I'm talking about.

I still wouldn't pass up a good deal on rx8s. They idled just fine. Someone recently said that ev6 works find on a Miata up to about 500cc. Then they get impossible to idle correctly (Why DW sucks). But my idle was just as good on them.

I bought my RX8's for $100 and dropped them in. I don't understand why people think absolutely nothing of going 200k miles on a set of stock injectors, but everyone is terrified of swapping in some much newer low mile injectors without cleaning/flow testing them. On a stock motor budget build its a perfectly reasonable option IMO and considerably cheaper than any other route.

if they were from a junk yard, and many are, they sat in who knows what kind of conditions for who knows how long. in that case, not cleaning/testing them is just asking for trouble.
Just depends.

Latest report I've seen says the GT500's also have some hot re-start issues. Also, the pigtails seem iffy. Still, if I were going from scratch, I'd have to consider them.
I got my Yellows for $40 and it cost me about $110 to have them cleaned and flowed. Prices include shipping.
Hot re-start can be tuned for. The NB1 seems to be pretty forgiving on AFR at idle, so idle is smooth until EGO corrects to 14.7.
For me, the worst part about the Yellows on Returnless is the ugly low end non-linearity. Basically a 1.55mS pulse gives zero flow. See some of the stuff on the MS forums on NL for some plots. I am running NL small pulse corrections, mostly as a learning challenge.
In the end, I think the data exists for making Yellows work fine for what they will flow, and I think the 220 WHP is probably a good answer. BEGI could get maybe, 280?
I still plan to go to Return Fueling with 43.5 MAP reference. I still think this will only make things better.
If I were running E85, or had to swap back for emmisions, then the ID 750's sound pretty good.
