From the reading i have been doing on Miata.net, this is very much the case.
Of course, you have to wade through pages and pages and pages of 'oh, this is what you get' and 'this is riduculous, i can't believe Cosworth is blah blah' and 'it's there fault' and 'turbochargers are better' and 'no there not' and 'what would you know' and so on. It's rather amusing. Particularly when most of the trolling is between people who have read about these mods, and those who have done them.
Anyhow, the main debate seems to centre around Corky Bell (who is on those forums) and BEGI, who have i think 3 or 4 customer's with their turbo kit on the NC. They are using the XEDE and having no issues whatsoever. Then there is the Cosworth crowd, claiming that Cosworth's stuff is better then BEGI, and the problem there exists with the Sniper/Delta Force tune, but then there's also those saying that the Sniper/Delta product is still better than the XEDE...
However Corky and the gang seem to be the only ones making reliable horsepower out of the LFVE engine in the NC using the simple principals of good, safe tuning. From reading those forums, the turbo cars currently come out in front. But even by their estimation it is still somewhat early days for forced induction in the NC. Mainly on account of the fact that neither XEDE nor Delta Force have completly opened up all the parameters in the factory ECU.
There are also a couple of aftermarket ECU options in Japan, it turns out, but they are also very limited in scope - remove speed limiter (doesn't exist on export cars anyhow), raise revs by 500rpm.
Still, as
THIS LINK shows, the basics of the LFVE engine are sound - if you've got the money and expertise, 800hp is possible
