Blow through maf is not that hard to set up correctly at all . Been tuning one recently - works great .

Needs changes to vac pipework (jet air and omp) , a decent straight section of pipe before the maf ,screens , and if BOV is VTA it should be mounted pre maf .

Hmm that's good to know.

What changes were made to the vacuum lines?
What size is the MAF housing? 2 Screens?

May be something to consider if it works well, I was planning on running pull through but I have to wait until I get the Manifold and Turbo installed to see if I have the room I need to make it work.

omp with esmiral becomes an issue when wanting to run a sohn. I think that with frequent oil changes and premixing you should be ok running this way

MOP and Jet air must connect AFTER the maf .
Stock maf housing size .
Would recommend a honeycomb 'maf straightener' as screens will blow out rather easily. One pre maf scree should be sufficient unless it is close to the throttle or large transition-bend.

Isn't that where they are normally?

Thanks I'll definitely keep that in mind when I redo the piping.

It's not just esmeril but I just don't get why someone can't just sell a turn key solution.
i feel this is a nooby noob question, but why can't you you just get rid of the microtech and tune it with the cobb, just like the greddy turbo?

Speaking of.. questionable systems.

Do new Greddy kits work yet? or do they still make everything explode?

Kind of an ignorant question.

But, the Greddy kit out of the box is unfinished and the E manage is crap on the RX-8. But the fixes are pretty simple to make it reliable which is why I chose it and had a upgraded turbo built.

Haha it was said more jokingly than anything else..

I will likely be buying a MM upgraded Greddy soon. But it amazes me as well that so few companies are able to make a perfect kit first time-tound.

there are only a few companies that make kits for our cars. those companies typically don't go hours on end reading the forums to understand all the problems other kits before them have had. they also have different end goals and they all have to make different sacrifices. no kit is perfect.

if you are not buying the one in the for sales section (not sure if that turbo is even available anymore) then good luck finding one.

The greddy turbo is the most "popular" kit so it has the most usage. There has been countless research and development (on the consumer side) that make this kit the easiest and most reliable to go with. That all being said, the greddy kit isn't the most powerful but it is what I am happy with.

I am pretty sure we can work out around it, but not 100% positive.

I am not going to sell a kit that will break other parts. Premix is a lot less hassle than having to replace Oil Metering Pumps

I am big believer in premix (I premix and run the SOHN) but premix does not address one of the main reasons the oil injectors are there in the first place. The Series I Renesis doesn't have enough oil injectors as is, so I wouldn't think omitting them completely would be a smart idea. For me I think changes made to the Series II motor speak for themselves.

But what do I know, I'm no expert.

I don't have time to do a giant serial-quote answer, but I'll try to address the questions and the oft incorrect answers that are in this thread.

The AccessPORT will work on nearly everything. There are some things that should be addressed if you want it to work well and most of those things must be addressed if you want e-Tuning to be your calibration option.
The MAF can be draw-through or blow-through. It doesn't matter.
It just needs to follow all the conventions that have been laid out on this forum over and over again.

Screens do NOT blow out. I don't know where that suggestion came from. Perhaps the individuals that may have experienced this used the wrong materials. I don't know.

Pre-mix only is a viable option. It has been done for years. It is highly inconvenient and dirty, but oil injectors (and the OMP) are not a requirement, just a good idea.

The MazdaManiac GReddy upgrade will be available again soon, but in a wide array of variations and configurations and through BHR instead of directly through me. We are building systems around the 35r at the moment (as the most "intrusive" version of the upgrade), but the "special-sauce" GT307xR will be coming back.

The GReddy kit straight out of the box works really well, especially when coupled with the AccessPORT. It is only once you start to turn up the wick (which everyone does because no one is sensible) that its shortcomings become apparent.
If you want a ~250 HP RX-8, it is the easiest and most economical way to do it.

If you want an absolutely comprehensive system built by people that aren't idiots, then Turblown is your best option. SFR is a close second for the same reasons. Both will work with flash tuning perfectly.

1point3 - Dude! Wazzup?

There are 4 people in this thread that would disagree with you on that . This is with the OEM screens on N/A engines.

https://www.rx8club.com/series-i-trouble-shooting-95/broken-intake-mesh-screen-118307/page2/


Also the blowthrough setup I mentioned above - he fitted an oem screen as well which blew out within days . Having no BOV could have been a factor in that

You can't use an OEM screen for obvious reasons.

I also explained away the concerns in that thread.

Properly fitted screens made with the correct material will not collapse or be sucked through.
