If you can hit 150rwtq at 2.5K on a built 1.8L, then I'd expect the same turbo with a similar setup a built 1.6L to hit it before 3K, which is a great benchmark to hit with being able to hit over 300rwhp with the same turbo.

The 6255 won't spool any faster than a 6258.

OP can't fit a 6258 on his FM manifold, though. He would be able to fit it on one of our upcoming EFR-specific manifold/downpipes, though.

Ahh right. I have FM manifold and gt2560r, so I would need a new manifold and downpipe, the bill grows.....

When do you expect to have you manifold/downpipes for sale? Do you have an approximate price?

We'll announce final pricing when we release, but expect ~$2500 for the manifold, turbo, and downpipe.

Could a FM or BEGi Manifold not be drilled/re-drilled for an EFR?

Here is my crazy idea, I haven't yet looked into if it is possible. I got the idea from Soviet. When his first EFR blowed up, he wanted to put his T25 back on, but the downpipe didn't quite fit. I am thinking I might try to get a manifold and DP that fit the EFR, and get a T25->v-band adapter made that might allow the T25 to work with that DP and mani. Wishful thinking? Probably.

But if the EFR doesn't use the same flange as the T25, then I guess that won't work.

Nuge, thats the impression I got, the manifold would work (unless the turbo hits the manifold), but the down pipe would come too far forward because the EFR is longer.

Right, but the turbine outlet is a 3" vband. If you can get a T25->3" vband that is the same length as the difference between the EFR and the T25, in theory right? I want to build my engine and have a crazy beast like Soviet, but that would cost more than I am willing to spend in the short term. Possibe? Or STFU noob and lurk moar?

Unless you are willing to cut the package shelf out of the car (same as what's required to fit an LSx), you cannot center-mount an EFR6258 on a BP in a Miata. You have to mount it further forward, which is why you can't use a standard FM or BEGi manifold with an EFR6258.

Ah, so EFR kits are going to have to say, "Turbo no hit frame."

This x2

I bought a FM2 manifold from Flyin' Miata's deal of the day with the intention of using the 6258. After some measuring I found out it was going to need shelf cutting or run the downpipe out of the hood

I would love to build an EFR setup from the beginning.

But in addition to the costs to run a T25 (or really any turbo with stock internals), I would need a six speed (~$700), a built bottom end (at least $1500 unless I find some great deals), and a coolant re-route (from $50 to $300 depending on how DIY I do it). So we are looking at a minimum of $2200 in supporting mods in addition to the extra $1000 for the turbo (which really I don't have a problem with) and all the other stuff.

If I can cheaply do both, I will wait until next winter to build my engine.

BTW that is what depresses me the most about all this turbo stuff. $1400 for a turbo? I can totally afford that. It's all the supporting mods that add up.

But who knows, I may go the Faeflora way of shooting for ALLOFIT on my first ever turbo build. Still need a house (more importantly, a garage) first.

Savington, good to know that it is just the turbo placement from the FM/Begi manis that don't work. I was going to go with Artech anyway, so that's not a problem.

So will the 6758 fit on an fm manifold? Just have to make some room for the downpipe? It's not really a problem is it? A bit of cutting and welding. Don't think it would take much strength out. The was planning on making a little room down there anyway for a better flowing downpipe.

Your "not really a problem" is someone else's "really a major problem". Personally, my skills would fall under "really a major problem". For me, it is difficult to build an acceptable downpipe with a Garrett T2 turbine on FM's or BEGI's manifold. The EFR's are significantly longer pushing the downpipe even closer to the firewall. Ya know, like Savington already said.

No love for Precision on mt.net. I may have the only one and that's apples/oranges. Still sittin in a box. I only tried it cause I got a good deal and because EFRs were not reliable/available at the time I purchased it, but a optioned up 5558 PTE (ball bearing and Vband) is basically same price as an EFR, plus you'd still have to buy the EWG and BOV. While the PTE looks very nice in person and I am very happy with its apparent quality, much nicer than garrett castings, the EFR's i've fingerfucked at trade shows make me go oooohhhhhhhhhhh
