Greddy or new begi kit or MS
Still decieding on what to get. Theres the greddy kit
http://item.express.ebay.com/GReddy-...mdZExpressItem
and then theres the new begi kit
http://www.bellengineering.net/Pages...ems_BEGiS.html
or should i just get the MS first and then get the turbo after i get the money or the other way around.
and i already got the 550cc injectors so i was planning on getting MS to tune them and use them, but then i could run the stocks for a while untill i get the MS if i get the turbo first. What should i do??

I currently run a used Greddy kit, with an RX-7 intercooler, custom piping, custom intake, MBC, Bipes, 1.8 injectors, Walbro 190hp, and an O2 signal modifier. I am pushing about 190rwhp with this set-up.
Having said that... Buying the BEGI "S" turbo kit is an absolute NO BRAINER! As others have said it is better everything!!! If I had known this a year or so ago I would have bought the BEGI kit... No question.
Regarding the Megasquirt... I think the most important question to ask is how much horsepower do you want to make? I think the Megasquirt PNP is a great stand alone for the boosted Miatas, but there are plenty of folks that still have the Mass Air Sensor, fuel pressure regulator, etc... that still make great horsepower and still have stock driveability. Just something to think about.

noise there is not specific limit to the hp you will make at 15 psi. I have seen a modified greddy system pump 180 and i have seen them make 250 whp at 15 psi. My but dyno puts me at just shy of 300 with 15 psi. But i run a very agressive tune etc, and my turbo is closer to the size of a 2860.

For the 1.6, there is some revision that needs doing to the EO for it to be "proper".
Presently, D-349 (the '90-'93 EO) specifies an IHI or Aerodyne turbo and requires an intercooler. Similarly, D-349-1 ('94-'99) while it does call out the Garrett and lists the I/C as optional, does require "two supplementary fuel injectors ... controlled by a boost pressure actuated electronic circuit."
I've talked to Corky about this, and he indicates that so far all of his CA customers have been able to pass with the current hardware under the old EOs. They do in fact have the adapter for the two injectors available if anyone needs it, though the electronics are left to the customer- should be easy for anyone with an EMU / MS.
He also said that they do intend to have the EO modified to more accurately represent the current products.
In case anybody doesn't know, the California ARB database is searchable here: http://www.arb.ca.gov/msprog/aftermk...es/amquery.php
Not that the Greddy EO is much better. The part number listed in D-397 is different from the one on the sticker.
From a purely technical standpoint, there are no Miata turbo kits which are presently 100% CARB-legal for the 1.6 Miata. Fortunately, close seems to be good enough for most inspectors.

Great info, Joe. So, uh, I'm sort of surprised that the smog inspectors would miss an intercooler on the 1.6; I presume Corky's comments are mostly directed at the later models and their injectors.
I'm debating the Greddy vs BEGI kit and Carb is key for me. +$650 on the BEGI for the IC makes it double the Greddy price.

Uhm... Yeah. I'm not sure I follow you, Brainey. But,
Well, bear in mind that the Greddy kit does not include an intercooler either. In a true apples to apples comparison, the Bell "S" is $335 more. And it's worth every penny and then some.
The intercooler is not necessary at the levels of boost you'll be seeing on either the base "S" kit or the unmodified Greddy. That's why they don't come with them. Regardless of which kit you choose, when you decide to increase the boost you'll be well advised to buy or build an intercooler system. And regardless of which kit you choose, you can either pay $500 - $650 for a pre-fabricated intercooler solution, or come up with a DIY setup of your own.
