If you match my price that I get it for then I likely will. lol But at that point you would be losing money.

I ran older DW1000's back in 2010/2011. I think they were EV6 at the time. I had such a horrible experience with them. After that I cannot ever recommend running any DW injectors. The ID1000's I have bought have been so much better. It is worth it to me to get an injector that I know will be great. If DW switched to EV14's they may work fine, but I won't be the one testing them.

The AZ6 has been proven reliable in low torque 500whp+ cars again and again. Ive got some "built heaps never broken any" numbers and ideas I could share.

Also OP, 10.5 is too low for E85.

Please explain how 10.5:1 is too low of a compression for E85? Frankly I do not believe that to be true in the slightest. There is no "set" CR for running ethanol. Would i benefit more from a higher CR? Yes. Will this CR be better than anything below it? most certainly.

IMO, 10.5 is a great medium for that extra timing that you will want. E85 will play a big factor. Also, seeing how the Fab9 setup favors your flavor will be very interesting to see

with 10.5 you can run low boost on pump if you wanted to. go higher and you lose that option

Mid 11s still want significantly more timing than stock motors on premium.
What vlad says is a genuine consideration for my customers but only those who want to pay for flex fuel.

My last project was a Mazdaspeed 6. Direct injection, so we did not have any options for aftermarket stock injectors, so we decided to add an additional fuel rail on the intake manfiold with 4x 2000cc injectors, motor had 10.6:1 CR. On 93 alone it made about 500whp before it was knock limited. Switched to a 50/50 mix of e85/93 and picked up over 250whp and at that time was limited by the turbo more or less. I do not see any issues with the 10.5:1 pistons i have chosen.

With the Miata i also plan to run an AEM flex fuel sensor.

Im not saying it wont work, Im saying that for a BP, dedicated E85, 10.5 is below optimum. Specifically I can say thats true anything this side of 400whp.

If you have something different sweet, it wasnt an attack.

Well, I FINALLY got everything back from the machine shop, I was initially quoted a two week turn around time, and it ended up taking eight weeks total... smh

Oil pump should be here soon, which means I "should" be able to get the motor assembled this weekend. Once that is completed I will be able to get the turbo mocked up and lines sorted out so I can drill/ tap the oil pan.

Baby steps

So, when I purchased the BP4W head, it did not have the nuts/ studs for the intake/ exhaust manifolds to bolt to the head, so I called Mazda up yesterday to order them, and they want $11 per stud.... NOPE, not doing that. So I am curious if anyone knows of a less expensive option or the dimensions/ pitch of them so I can attempt to replicate them elsewhere.

Oh, and I got the oil pan back from being cleaned yesterday, so I was able to get the engine on the stand now. (yes i realize it has to come back off for the oil pump, it was going to need to come back off anyway for the baffle/ pickup/ and to drill and tap for oil drain.)
