Nice.
And it will slide in from bottom? That's impressive, I've yet to see a 1piece dp with that many bends do that.

Not a production part, but a representative prototype. Details may change (weld locations, bracing, slipjoints, etc).
That sounds like a lot of work.

Make another casting.

EFR6258, BP6D longblock, stock NB2 exhaust, and a low-boost actuator with 5 turns of preload nets me 4.5psi peak, tapering to 4psi at redline. Hopefully that puts the stupid "can't run a 6258 on a stock motor" BS to rest.

See you all at MRLS tomorrow

Now put a free flowing exhaust on there and do that again.
Also you're gonna flog this setup at the track all weekend right?

I have a 3" Enthuza on the shelf that will go on next week, but I really doubt that it's going to go from 4psi to 12+psi just on that.

Come get a ride this weekend

Would have loved to get a ride, but couldn't make it. Hope all went well.
So far I've only messed with 1 EFR miata and it creeps pretty significantly on a free-flowing setup. When I spoke up about it, several others chimed in with identical results. Perhaps defective housings/wgas/whatever, but calling experienced member's first hand results "stupid BS" is really kinda insulting. Also the creep happened past 5500rpm, where the stock exhaust would drastically choke the system and "help" in this case.
In for results with free-flowing system. I hope your results are good and opposite of what some of us have experienced thus far.

Waiting for a bolt on solution patiently. Too lazy to fab up piping etc. I know this is the setup I want.

Ghuys, this thing is legit. I got to finger the SLA and poke around the silver car a bit. After dealing with my ARTech tubular (that is super awesome BTW) I'm still sorely tempted to buy the TSE manifold and downpipe once it readily available. I've handled both the FM and BEGi cast manifolds and they don't hold a candle to this thing. Flow paths are SO much better than any other cast manifold I've fingered so far.

Compared to my ARTech:
  1. Turbo sits slightly lower
  2. turbine housing inlet is almost centered on the #2 runner (mine is further forward
  3. because the turbo sits back further, there is actually room for "activities" in front of the turbo (PS reservoir, cold air box, etc)
  4. downpipe angle/radius/clearance looks better than mine (mine is REALLY tight)
  5. generally just better clearances everywhere actually
  6. its cast (durability)
  7. great clearance on PS/AC equipped cars

I really like that the turbo is snugged up to the block a bit better than mine, giving more clearance everywhere. Mine looks like its kinda hanging out in space on its own. For those that have not handled an EFR, its no lightweight and my manifold makes me a little nervous with all that weight out there sitting on the manifold.

It is win, do want.

Savington, do you mind if I post the pics I took?

I quickly snapped these on my phone so I could reference the clearances on my own setup.











They are HARDLY comprehensive, but I think you all will get the gist.

Any pics of IC piping routing?

Looks "traditional" to me.

Traditional IC pipe routing. With the turbo centered on #2, the compressor outlet dumps just ahead of the factory coolant hose, so the IC pipe sits between that and the A/C compressor. It then exits straight under the forward UCA bushing, through a hole in the undertray, and then runs along the outside of the undertray and into the intercooler.

2002 BP6D VVT Longblock, stock internals (10:1 CR)
Trackspeed EFR B1-frame 347SS cast manifold
Trackspeed 3" downpipe, Stock NB2 exhaust
BorgWarner EFR6258 turbo, 0.64a/r T25 turbine housing
MSLabs MS3 Basic ECU
Flow Force 610cc injectors
5psi intercooled

Everything else stock. Timing and fuel is very conservative, no doubt there's power left on the table, but this is what ran all weekend at MRLS. I'll put a 3" catted Enthuza exhaust on this week.

Datalog attached below.

Looking good to start with. Any pictures of the down pipe? Got a price for it yet? When are the group buy orders shipping?

Here's an awful pic of the downpipe just before finish welding and installation. I'll try to get some better ones this weekend when it comes out to get drawn up in CAD. Expected retail on the DP is $500. Kits shipping late December or early January.
