This was round two for our crapcan Miata, and we weren't about to return to the track with a car that wasn't any faster. There was one question, though: How do we make our car faster? We already had springs, shocks, sway bars, bushings, a limited slip, and sticky tires. There was one department we hadn't addressed, though: The engine. …

Having just this morning purchased a 16G for my miata, this is extremely relevant to my interests. I'll be following along very closely

Why do you have to have articles like this? My bank account may never be the same

It's only $1000! Cut hole in hood + vertical dump pipe = profit

Next go around do the BP swap and visit Carlos and the gang at BP Performance Specialty (in Florida as well) about some of their GRM friendly parts that will play nice with your setup. They have modified EVO intakes to help flow more on the cold side, hacked tunable EVO ecus (though you have that covered) and possibly most beneficial, Toyota coil on plug conversions to assist the ignition at higher RPM and under load. cars with heads from a 99 and the exhaust cam swap are seeing 160HP N/A at the wheels, with boost after fueling, rods become the point of concern, though there are options to resolve that concern for roughly $200, though that entails taking on a much larger project that always ends up costing more as you start checking off boxes (boundary engineering billet oil pump, bearings, machine shop cost etc. for example).

Now you have me wanting to get another miata to BP swap to build a pair of BP powered monsters that happen to power different axles.

20G billet wheels are a cheap easy upgrade if targeting north of 230HP in a BP.

Problem is I want a v8 too. The girlfriend's FB is getting the miata's drivetrain.

I forget is the BP the 1.8?

I just want more out of my 1.6. I may even do a bare bones fuel pressure regulator, manifold, downpipe just to get a little more while saving up for everything else. I'm really not looking forward to doing an ecu swap.

My short term plan was to put a header and exhaust on my 1.6 miata. Long term plan was to do the monster 5.0. But some dude us trying to talk me into buying his 1.8 engine and turboing it or supercharging it. So now im all mixed up.
