Hmmm...not sure on the crush washers...

I'll have to double check tonight, but I don't beleive it did. Can I get these from the dealership?

[MazdaBoy2.3]

Crush washers Included!

[MazdaBoy2.3]

How exciting.

I realize now that you're just topping up. If you have fl22 in the system, then I guess you're stuck.
When it comes time for a full system flush, don't waste the money.

INSTALL IS 2 DAYS AWAY!!!!!!!!

@smoogs12; - all that quick work from you and now it's been sitting for a month. Sorry!

[MazdaBoy2.3]

Performed a ghetto test of the wastegate with my bike pump (reads 0-120psi). The arm seemed to move every time right below 15 psi. Probably do a more official one tonight with a boost gauge T'd into the line.

There's a pump you can buy at HF for 10 bucks that plugs into the cig outlet. I'm going to buy one for a boost leak test on my car, I can't figure out where my leak is coming from. Bike pump is super ghetto

Edit: I don't know what the pressure on that pump is!

It may be super ghetto but in theory it's doing exactly the same as a hand pump. I do have an electric pump that tops out at 30psi maybe I'll give that a try too.

Wastegate test.

Won't be on day of install.

But it's in the mail.

[Tokay444]

So, how is?

It's in, but having issues with the return line.

Apparently this is not designed for the stock dp...

Rob found this. Should help with the angle.

How did you manage turbo, and stay stock dp?

With all the whispers of creep on the Internal wastegate ATP turbos, I decided a little extra protection from the stock cat/dp would be a good idea. I'm also only targeting 350 hp so I should be able reach that without upgrading. Sent a batch of logs to @rfinkle2; and all seemed good, so it appears to be working.

[MazdaBoy2.3]

This came in the mail yesterday, and the adapter that hopefully gives me the clearance I need for my oil line is sitting in my mailbox atm!

[MazdaBoy2.3]

Fail....

Looks like it's down another few days...

What was the adapter for?

For the block. I was hoping the angle would help but this was clearly the wrong size. Looked so promising too!

Damn that sucks sorry. Maybe grab a catless eBay dp for now and just clear the cel? Might be the cheapest and fastest way to get you going again.

Elongate the holes, and bolt it on.

[MazdaBoy2.3]

Got it together!

Heat tape looks like shit. But I think a smart add.

[MazdaBoy2.3]

Here are some early virtual dynos for my progress.

Was doing 3rd gear early on, but switched to 4th for the latest revision.

Looks like it's coming along nicely. Im very interested in what your final 93 results will be.

Another log/revision, another 10 hp. Should be at 300+ with the next revision and then it's on to e85! Note: the 93 is just the dd tune, we aren't trying to push it crazy hard. Still on stock dp and 2.25" intake!

[twenty5psi]

Not bad considering that turbo is choked with that intake/stock dp.

The htp will be going on soon. This is more of a test than anything to see what we will be able to open up with the 3"intake.

I don't know that is the case tbh. The intake may be a small bottleneck, but there is sufficient data @ power levels < 350 that the stock DP actually performs better than many aftermarket DP's.

Fair enough on the DP; it doesn't seem to have a huge effect(if any) at lower power levels. That 2871 has a 4" inlet if I'm not mistaken, that's a big drop down right in front of it to 2.25", probably not huge either but I hope he can pull a bit more power out of it on 93.

[ImGryssLOL]

I'm looking for a "BLT" myself so I'm very interested to see how it turns out with proper tuning, good luck

I agree that a larger intake would stress the turbo less. The Garrett inlet designs are funny that way.

The 4" OD of the inlet is actually kind of a fake out, given the actual intake inlet is not much bigger than the compressor wheel.

Completely agree with you that this system could breath better, but we are trying to squeeze the goal out of minimal mods for a challenge.

Up to this point i have been very happy with my results. On pump gas my k04 I was struggling to hit 275hp (i blame it on crummy gas in my area). So this turbo is clearly working well.

I know you guys aren't trying to push this little guy hard, but I would be really interested to see how far you can get on a safe but aggressive 93 tune. When will the 3 inch intake be going in? Our mods will be very similar so I'm especially curious! Is there a target for the 93 tune?

I'll have to defer to Rob @rfinkle2; on what he thinks is left in it.

Initial goal was 300 though.
