The '94 still needs two of the injectors moved over to the center connector (1 and 2). 3 and 4 can stay in the OEM harness.
Fuel rail depends on which intake manifold you use. For some reason I remember the '01 rail not working for some reason, but the '99 rail does - but the '99 rail fouls the intake manifold a little bit. Whatever you use for an OEM rail, you use the 1.6 FPR in place of the fuel damper.

e: I assume you found this thread? https://www.miataturbo.net/aem-59/aem-cam-crank-ig-inj-phasing-setup-vvt-motor-27028/ These are basically the settings I used. What do you mean by "cam and crank angles"?

For reference there are 3 different NB fuel rails. The 01+ will not work with the return system. Between the years 1999 and 2000 they used 2 different rails. I am not sure if they are year specific. One of them has the flange for the FPR on the bottom and will not work with a return system. The other one had the flange at the very end and a NA FPR will bolt up and work.

I agree on the bargain hunting.. but there are quality turbo parts for sale in the classified section all the time so it is doable, just seems nobody HAS done it and kept the power down to a reliable level. Boost is addictive I guess and nobody has the restraint to keep it low power.
I'd love to see somebody with a 150 whp turbo beat it on the track and see what happens. Proper studs and decent radiator / coolant reroute should make it pretty reliable no? I guess your point is.. "pretty reliable" isn't good enough and not on the same level as the VVT. I get it.. just can't find VVTs around here (eastern Canada) as easy as that so one looks for other options.

How much power does one cut off the above setup compared to just dropping the 99 head on a 1.8L block? I guess that is a reliable 130whp?

The difficulty isn't just about the about the power, it's about the reliability of the actual components. Inconel studs are a big step, but every single component has to be high-quality if it's going to survive the kind of beating that the rental sees. No eBay manifolds (obviously), no shoddy downpipes, no rubber water lines, etc. You simply can't skimp on ANYTHING when reliability is the top priority.
I'd bet 5-7whp. It doesn't really make sense to spend all the money on the ECU, exhaust, intake, dyno time, etc. and start off with a lesser bottom end, though.
I'll go a step further.. a run of the mill 94-97 with the EFI and intake manifold (everybody has the IHE already so lets leave that out) should be about 130-135 whp?
Appreciate sharing the knowledge. Just trying to get a feel for how far to go with an NA build. Seems like 140-145 whp with a 99 head on old block is pretty darn affordable ($300 head, $300 Megasquirt, $250 manifold, and then the usual IHE).
Thanks
Tim

I could, but it wouldn't do you any good since the injectors are wired differently. You would need to completely alter the ignition and injector phasing. All of the cam/crank sensor setup info you're after is in the AEM section, look for posts from Jason Cuadra and you should be able to find it. I'll see if I can post a couple of links in a second.

I will definately still have some questions.... im having a hard time wrapping my head around a few of the concepts being that i havent played with the phasing and such to see a change first hand.
That thread covers the cam angle sensor and the crank angle sensors. you are running the VVT cam angle sensor, correct... not a 1.8 CAS?

Just got back from Infineon, where we got every possible kind of condition.
Session 1: Wet
Session 2: Wet but dry line forming
Session 3: Complete dry line
Session 4: Dry line and starting to pick up grip, flat through 8/8A and 90+mph through 10...until the skies opened on lap 6 and by the end of the session I'm back to wet lines
Session 5: Wet lines
Session 6: Wet lines until they black flagged for lightning
Between Dad and I we did eleven 20 minute sessions. 40 minutes on, 20 off, all day long. 2.5 tanks of fuel. Never opened the hood.

Still waiting eagerly for the Xida CS. I don't drive my car in the rain, I don't find it enjoyable at all. The rental is fun in the rain but I enjoyed sessions 3/4 infinitely more than the rain sessions.

Sav took me for a ride in the rental last Saturday on the streets of willow. I don't know what that lap time was, but it felt pretty frickin fast.
An na riding on unmentionables, I was blown away. Sav is a great driver. The rentals only draw back was on the straits, unless you like to take a breather while waiting for the next set of corners.
Good times.

Do you mind sharing your AEM settings for VVT?
I am going to try to get my car driveable and this would help...
Obviously it will need to be tuned to my configuration being that im turbo but it would give me a solid starting point.
The thread on setting up AEM on the vvt engine never had a completed calibration shared here or on aem forums.
Thanks.

This car ever get an intake manifold swap?
Also, still curious as to the benefit of the 01+ bottom end vs. the 94-97? How much CR ratio difference is there? Any other actual difference?
MT.net misses this car..

Not yet, been busy with other projects and adding power to the stone-reliable Rental hasn't been a big priority. It is getting a fresh shortblock over the winter, so the Squaretop will go in then.
Getting it done at SoW this past weekend:
