Changes to Boundary Oil Pump Line
 

Hello Everyone,

I have a couple of changes to the Miata Oil Pump Line that are coming VERY SOON!

1.) We will be discontinuing the sale of the standalone oil pump gears. This is for a couple of reasons.

1. There are actually 4 sizes of oil pump gears and of the 4 different types it is near impossible to tell the difference between them without high precision tools.
   
2. Inventory is a problem, we have at times upto 100 gears in stock at anyone time. Sometimes we run out of a particular type and we have to machine down gears for that particular style. This drives price up!
   
3. Wear in stock housings can cause pump performance problems and short life. Determining the uneven wear of a housing is about 10X more difficult then determining if the gears fit. It truly requires some expertise to do, and there are no known written documents on what is acceptable and unacceptable

With a discontinuing of a product line, we're giving life to new one.

News item 2.) The introduction of the stock replacement billet oil pump!

I have not set a price point for this yet, but I'm shooting for mid to low 200. These pumps will be blue print assembled in the same way as the higher end oil pumps, but they will be a value option to those who simply want a stock replacement on their reasonably well built road racer.

You can expect the change to occur before the end of the month.

Thank you all for your continued support of Boundary and have a great day!

So the new billet pump comes with your spiffy billet gears already matched?

for 225-250?
nice. i just bought an oem pump for like...135.
it would have been nice if this was available.

Yup! No more questions about fitment or performance. You get a pump put together and ready to go with its own blueprinted sheet!

Its been in negotiation, and ultimately we aren't done negotiating yet. This has only recently become available. I just wanted to let people know ahead of the change so they can plan their winter/spring builds. Sorry this didn't work out quite right for you.

Travis, I've ben in contact with you about the gears I recently ordered and wanted to upgrade to the ful pump. Do I have this option or will I have to wait?

Thanks

:drool: This will go nice with my summer build.:x:

Love the full pump option!!

I haven't regretted the decision buying mine once at all!

This fits my needs perfectly. THANK YOU!

Sounds like a win win for all....at a reasonable price.

Group buy introduction pricing? *Hint*

Yeah, that.

Glad I saw this thread. I was going to buy gears this week, but I can definitely wait for next month. Sign me up!

+1

I'm about to order all engine parts soon as well.... I will get these 100%, hopefully I can get in on the first run of them or whatever.

Great news you wont be selling just the gears anymore!

At least if/when the next customer purchases one of these new complete pumps and it fails in a brand new built engine, you wont be able to worm your way out of any responsibility. Or at least not as easily lol

I'm not really sure what your referring to here...

On the website it states this:

• These gears are all individually inspected to meet factory specification in an oil pump housing. The gear sets are fully de-burred and pre-lapped. There should be no other steps required to install, but always check clearances in your housing to ensure proper operation.
  
• In the Mazda Miata official shop rebuild manual which mechanics and engine builders should be following it says to check all clearances. (attached)
  
• In addition to this as I have specified to the manufacturer, they are supposed to ship each set of gears with this very sheet in the package so you do not forget.

I don't know how I could be any more careful with telling people they are responsible for making sure their oil pump assemblies are going to actually pump oil. The reason we charge more for the oilpump assemblies we make is because we put the extra labor into them and control everything, there is no guess work. When you put on any of our built pump assemblies it functions, there are no extra steps.

My apologies if you or a friend had problems, but this is my ultimate solution. No more gear sets sold mean that there can be no liability or error.

Sounds Great
Do you expect to see pressure and flow increases in this blueprinted design over an oem stock one? If so, how much? How does this new pump compare to the upgrade options that you also offer?
Thanks

Sandy vag for not bothering to do the work required on your end, bud? Micrometers and feeler gauges are usually pretty accurate devices if they ever make it out of the tool box, lol. Seems like there's not much to worry about if everything inspected is within tolerances... if you check the tolerances... if you check the tolerances... if you check the tolerances.

Will the same pump work in VVT and non-VVT applications?

No, there shouldn't be any significant increases in flow with this one. The tolerances are likely to be tighter and that may transfer into just a little bit more flow but not much. This pump is built to be bullet proof, and high value.

I wouldn't run it in a VVT motor, you need more oil flow for that. Street Strip would be your best bet. I'm going to put a guide together on each pump today so its easier to choose!

Thanks!
