This is what i've been waiting for if I were to get another rotary powered car. That is an extremely reasonable price. Anyone looking for more power in the 300-400 hp range for a daily driver should consider a rebuild and purchasing this setup. This is nice.

Regarding the flex pipe, how much is it actually doing since the front end of the midpipe doesn't have any support except for the downpipe itself? It seems like the midpipe would just sag with the flex pipe and bounce around. By the way, really like how this turned out, so don't take this the wrong way. Just curious.

^ that midpipe should not move. It's mounted to the turbo which is mounted to the headers... It looks solid.

Right, without the flex pipe the midpipe would not move. However, there is a section of flex pipe included to weld onto the end of the midpipe to allow for engine movement.

I'm trying to figure out if it's necessary since the midpipe already hangs freely at the down pipe end. I could see the need for a flex pipe if the midpipe was attached to an exhaust hanger or other mount at the down pipe end, but it will only be attached to the down pipe.

Where are you seeing a flex pipe at? The only flex pipe I see mentions connects the wastegate to the midpipe. The midpipe still makes a solid connection to the downpipe... right?

When Elliot called me yesterday to tell my my low mount kit was complete he mentioned that the downpipe was to short to include the flex pipe so he is going to send me a flex pipe to have welded to my midpipe.

yes the downpipe is too short to route the wastegate back into it. That's why you have to route the flex pipe from the wastegate to the midpipe. I think I'm saying this right someone jump in and correct me if I'm wrong.

What you are saying makes sense, and I anticipated for the wastegate. I may have misunderstood, but I am leaving the waste gate VTA, so not sure why I am getting a section of flex pipe. I thought it was for the downpipe to midpipe. Probably confusion on my part :-) Anyway, I should know when it arrives next week.

I appreciate the link, but those look like the flanges. What I am after is the actual electrical connector. I could splice and extend the existing connector, but I prefer to make an extension with male/female connectors, if possible. Also, for this kit to be Cobb compatible requires two MAF sensors, one close to the TB for IAT and one up front at the intake over the crash bar for actual airflow. Elliot said he welded in two flanges. So even if I spliced I would need an additional
connector for the second MAF sensor.

Not true, you just need a separate IAT sensor wired in, the stock MAF has the MAF Sensor and IAT sensor in one unit, You can just disconnect the wires for the stock IAT sensor and wire in a fast acting IAT and place it in the charge pipe.
It's documented here....https://www.rx8club.com/series-i-do-yourself-forum-73/diy-iat-sensor-turbo-164751/
I would recommend using the GM sensor mentioned in the last post.

Sweet thanks! Still would like a set of male/female MAF connectors to make an extension, if anyone knows where to find them. The actual airflow sensor is being moved up towards the front quite a ways...

Excellent work Turblown!
I hope this pays off for you guys. You're definitively pushing me closer to a FI setup when I go for a rebuild.
I guess you're gonna dyno one of them in a not too distant future?

trace the maf plug back to the main loom running along the wheel arch. carefully open the split tube and strip out the maf sensor wires. you can then take the MAF wires out of the loom all the way back to the front of the fuse box and will have ample length to mount the maf where ever you like. get some new split tube for the extended MAF wiring and some electrical insulation tape and re-wrap the loom.

Just tried this and it extended right out to the middle of the crash bar, should be perfect! Even had some split loom tubing left over from my guage install...
Thx again!

Got clarification from Elliot today regarding the flex pipe. He confirmed it is definitely for downpipe to midpipe, not wastegate to midpipe. He also said it is not necessary, he is including it in to provide flexibility in case fitment of downpipe to midpipe is slightly off.
Tracking shows boxes should show up Thursday....

The low mount is installed and driveable. Question about IAT wiring. I've read Brettus' DIY for wiring in a second IAT sensor. I have two MAF sensors already, and the plumbing to the throttle body has a MAF flange, so instead of buying a stand alone IAT sensor I plan to just use the second MAF as the IAT sensor. I'm just tring to confirm the wiring on this schematic:

Am I correctly understanding to "Y" connect the "4U" and "5U" connections so the go to both MAF sensors and then disconnect the "5K" connection from the original MAF and connect to the MAF sensor that is acting as the IAT?
