You'll have to email him directly for the EFR downpipe. While I haven't gotten a downpipe fabricated before, I can't imaging it being any cheaper than Kraken's kit. The issue with buying a ebay manifold and having it crack on you is that your downpipe works for that specific manfiold. It would suck if you had to get another downpipe fabricated when you eventually do switch manifolds.

goto his facebook page and message him direct.

its $900 for an EFR kit.

includes:

manifold
downpipe
oil/water lines and fittings
inconel studs
vband clamp for turbo

so its not just a manifold and pipe, it includes $200 in accessories that you need to buy anyway.

Personally, before I married a nice EFR6258 with a bunch of less than optimal supporting parts because it "doesn't fit my budget", I'd sell the EFR off for a decent price + tax return money and just buy a MKTurbo kit (the mid kit) which will have all the power your going to get out of a sub-par EFR setup on a stock 1.6

90-93 NA6 Turbo kit

Or, if you still feel the need to show your engineering prowess, you can opt to a DIY IC setup and go the starter package he offers.

Take a weekend to plug it all together and enjoy the summer.

Thanks for the info gents, and good points all around. I'm definitely sold on the manifold, I'll have to run the numbers and call some shops before I can sell myself on the whole kit, though. I will say again that it's not because I wouldn't like to have a gorgeous kit, it's a budgetary thing. But you guys are slowly convincing me to wait if anything.

Romba

Interesting thought, but selling the EFR is not an option.

$900 is a deal for almost everything you need. Add and intercooler and you are good to go. My EFR manifold costs more than that kit with an intercooler, i think it would be hard for you to beat your value in the kraken kit.

Going to throw my hat in with the Kraken kit. I have his 1.6 TD04 kit and it's wonderful.

The other, super budget option, is to take the flankes from the manifold you have and build a weld el log manifold. If yiu can get cheap labor, that's the cheapest way to go. But yeah, that manifold you have won't last more than a few hundred miles before falling appart.

That Kraken downpipe is really pretty. Totally worth it. And his stuff fits right.

I'd would not use the brass oil feed Tee. Those brass Tees tend to break, especially with the vibration-heavy Miata engine. I'd recommend the steel version that Trackspeed Engineering sells.

OP has a 1.6 so the hot side oil port is best to feed from anyway. M10 x 1.5 to -03 AN Crush Washer Seal Adapter or if -04AN is preferred M10 x 1.5 to -04 AN Crush Washer Seal Adapter

Artifex

Subbed. A budget minded build with the holy grail turbo is appealing to me. Although I have no personal experience with Kraken, I've heard nothing but great things about it.

With the number of turbo 1.6's I've read/heard about lately, I'm starting to consider going that route instead of 1.8 swapping first... Quick! someone talk me off this ledge.

Having a 1.6 turbo I strongly suggest saving yourself the money. There is a reason i am building a VVT motor to swap into the car. Dont get me wrong the 1.6 is fun but i was able to get the 1.8 for almost nothing so it would be silly not to do the swap. Also since you can get a VVT with flat top shipped from the uk for 1100 thats a hard deal to beat. Or you can find one locally for a couple hundred. Or in short see the below.

Romba

I'm only turboing the 1.6 because, as is the theme of this thread, I'm on a tight budget and want boost. Hindsight being 20/20, I should have waited and found an NA8 or NB when I bought the car, but I was excited and just wanted to buy a Miata. Long term (i.e. graduated and making real engineer money) plan is to do a built 1.8, maybe VVT.

EDIT: That said, this will still be a fun exercise in a budget build to watch, Artifex. Also, BorgWarner's matchbot indicates a 1.8 would yield an extra 26 peak hp at the same boost levels as a 1.6, which isn't exactly negligible, but can be made up for with more boost. That aside, I have no idea how the spool characteristics would differ between the 1.6 and the 1.8. I'm sure there's a difference.

More displacement = Faster spool

Romba

Well, of course. What I have no idea about is whether that 0.2L makes a noticeable spool difference, turbo setup being equal. I wonder if anyone has done a back to back comparison using the EFR's speed sensor?

sixshooter

iTrader: (12)

Uh, there's a whole thread on spool comparison data. Don't need a turbo speed sensor to tell how quick it reaches 10 psi.

Artifex

That's exactly what I'm trying to save up for. $1100 shipped for VVT and square top sounds almost too good to be true.

I'm pretty much in the exact same spot. I'm currently a junior, almost senior, in EE. I keep telling myself, "Wait until you graduate and make the real monies." but the craving for boost is real. 1.6 turbo vs 1.8/vvt turbo partially depends on if I snag an internship this summer.

Oh, and by no means am I trying to bash your decision or convince you otherwise. I'm pumped to see how this build turns out.

While this sounds good from a Miata perspective, i still find it hysterical that in the context of motors in general, just how BAD of a deal that is.

der_vierte

Oh yes!

I'm looking for deals on ebay UK from time to time and i have found a few VVT engines with intake manifolds for 200-300 pounds, even right now! My '96 BP was 150€.
