Yeah I'd definitely not place it under the trans like that. There's tons of room up top for it

I'd also like to know why that's not a good spot for the o2 sensor. It's away from damaging heat, easy acess, and within the recommended 12-3 o'clock range. 3 o'clock is the magic number, not 2. Also, there's no moving parts around it, and wiring through the shifter is not uncommon.

I wish I could have done 3.5" from the turbo back, but there's not much room to work with between the steering shaft, shelf, and tranny. The outlet on the EFR is 3" so I'd need a couple of inches behind the turbo for a transition before the first bend.

I'm sure the bigger exhaust alone will make a difference though. Adding a bigger exhaust to any factory turbo car with stock DP gives a decept boost in performance. I don't see why this would be any different.

Innovate says "Best position is between 10:00 and 2:00 position". 3 is def not recommended and in the case of my own customer, destroyed the sensor in 15-20 minutes IIRC. As usual, YMMV.

I've always though it to be between 12 and 3. Maybe they changed it, maybe I've been wrong all along. I do see a warning on their installation manuals that reads:

Condensation can form in the exhaust pipe and permanently damage the sensor.
6 o’clock is the absolute worst position to mount the sensor.
From personal experience alone, I would feel comfortable with the sensor in the current location, but, Jason, it's your choice if you want me to plug this one and place a bung on top, let me know. Not a problem at all.

The bigger piping makes it harder to reach your hands/tools in there to install and remove, but I suppose it's not something that will be coming on/off regularly.

Here's the install note:

Quote:
The bung must be installed in the exhaust pipe at the side or on
top, NOT on the bottom of the exhaust pipe. Best position is between 10:00 and 2:00
position.
The previous quote is a warning under it.

Same here. Never a problem in 10yrs of using them. Just to clear things up, Reverant's failed sensor was installed pointing slightly down. I place mine pointing slightly up.

Abe,

If possible can you place it in the same place as the last DP you made me, and just plug this one? Thanks bud

Jayboo, I'm sure that placement is fine. I've ran my car like that for a while and never had any issues.

Alas, this is your car, not mine. Just get it done and make 600whp.

Quick update, I went ahead and bought the 949 Twin Disk; I decided that it would be better then the Spec Stage V simply due to the street driving I do--even though more expensive. I figure it would be easier on the transmission as well, also, I also went ahead and got the 949 Carbon Fiber mirrors I have wanted forever.

Next decision is wheels...everyone has 6ULs, what do you guys think of the new Konig Flatouts wrapped in 225/45/15 R888s?





EDIT: I also contacted FM about a Quiafe transmission, I guess they have a few in stock...just waiting to hear back from them.

Very nice wheel for the price, although similar to the kosei k1. Not that that's a bad thing, k1s are very nice on a miata, but if you're concerned about originality...still going to be rarer than 6ul I suppose. Keep in mind they fit a 11" BBK, but won't fit a 11.75" BBK. Go 6ul for that.

I think they're very similar to Volks



EDIT: They even have the same stamps/marks on the wheel...strange?

6ul's are only present on this forum. Rarely do I see a Miata with them IRL. Good luck getting traction with 8 inch wheels and 9000 whp.

I second this. I've never seen a set of 6ULs in my day to day driving. If you like the way they look, the price, and a low weight wheel Id say go for it. Either set will look awesome IMO.

I would be running the same size tire if I ran a 9 and if I ran an 8. Whats the difference as far as street driving/traction goes? I know on the track a 9 is faster, but I am not tracking it.

Koings make knockoffs.

The Flatouts are CE28n knockoffs.

Almost done! The manifold and dump tubes will be ceramic coated as well. I am going to see if Abe can make the transition of the merge in the dump a little smoother, more of a Y merge then a T merge.
