I am running a T4 twin scroll long tube header. Soon I am going to ditch the turbo for something more streatable with decent top end. I am in the 2867 2871 3068 3071 range although I drove a 3076 ball bearing turbo and I was very impressed.

Let's do a trade in program. I'll ship My turbo for one of yours and Ill post the results!! Next set up most likely be a Precision Ball bearing Turbo since they don't require coolant for bearing cooling

Hmm... I wonder what the "best" way to handle that would be then. Buy a better 3" downpipe from off the shelf? Buy the Flyin Miata turbine outlet and have a 3" system created from that point back? Fab the whole thing up custom?

I am trying to hold off on buying parts twice and I feel that if I build the engine I will go EFR... I really don't know anymore. I guess this turbo could put me well over 300whp right?

Chiburban,

I'm having to prepare to rebuild my entire fuel system to support 500rwhp+. Based on my discussions with Curly, I expect to hit low-to-mid 300rwhp and completely max out my injectors, but still have lots of room left in the turbo.

Again though, that's what I expect. Wait until this weekend where I have more impressions. However, whatever you decide to do, just put in an order with Artech and be done with it - never touch the stuff again.

P.S. A back to back with Pinky's special manifold is finally happening as well.

one of my ideas is to go with the ARtech EFR compatible manifold but stick with the 4828 plus one of those 5 bolt to v-band outlets. Something like this: Garrett GT28 Turbo V Band Adapter- TREADSTONE PERFORMANCE

Adding an ARtech is still more money than I have right now to be sure.

It's the darn chicken and egg problem this whole car has been. Really I need to build the engine to take advantage of this turbo. However, even if I build the engine, I need to do the exhaust properly and if I am going to do the exhaust it doesn't make sense to spend money on that and keep the BEGI cast manifold... So an engine build means engine +manifold +exhaust.

Frankly, in your shoes, I'd wait on my final results.

With a BEGi cast mani and artech exhaust, I plan on pushing it to it's limits. If the maxed out results are meh, go with efr.

However, based on information I have, results should not be meh. We'll both see next weekend however.

Bumping this just to keep the data in one place...

My Miata is on the road after a long winter and after some shop time it will be going in for a heart transplant.

10.5:1
e85
ported head w/ 1mm oversize valves
ID1000s
etc...

Hoping to tickle 400rwhp for the glory pull. When I have more i'll post a link to the proper place in my build thread and possibly dyno thread.

We have made 375whp on a dyno dynamics, shootout mode, strapped tight with the GT2860rs 0.86, it wasnt ALLOFIT, but it was pretty close. 12:1, E85, ported cammed BP05.

We will see how it goes. Obviously dyno numbers are just numbers, but it would be nice to see if we can hit the target. Originally I was hoping for 380 but I am going to be optimistic
