Forsale is a friends Turbo NB. This isn't your regular Turbo'd Miata where a kit is just slapped on over night. This set up was strategically built over the course of 2+ years with nothing but quality parts and top notch labor.

Price: $10,000

YouTube of the Dyno session during 12-15psi of boost. If the video doesn't work, search "FuelTech Miata". The video still has some older parts on the car and have been updated since then. The car is tuned to 32psi.


Fully built 1999 Miata BP 1.8 (600 wheel horsepower capable)
ARP studs everywhere
Builder - BMS racing in PA.
Rust free
Never tracked

This is John's car right? Free bump for a car I have seen in person and can confirm no expense has been spared. The damn thing is a work of art.

So bump for a car that has fuel management worth more than most of the miatas on here haha

A 600 horsepower Miata is pointless. Why? Because you can't put the power to the ground. That said building an engine to be capable of taking 32psi of boost and running 10-12, or 12-15 psi is smart. It makes for a more durable engine. The diff won't be the weak link for a while. Great mechanical sympathy is required at power levels above 300whp to keep the stock five speed in one piece. The Mazda six speeds are notchier but can take in excess of 400rwhp. If you are worried about the diff, V8 Roadsters sells a kit that allows you to bolt in either a Getrag rear diff from the Caddy CTS-V, which can be had new from GMPP for about a grand. The other option from V8 Roadsters is to bolt in a Ford 8.8 rear, which can take that 600 hp without issue.

I think the seller has built a great car and gone about it in an organized and well thought out way. My only question would be the about the ecu, I'm not familiar with it. Is it a piggy back or full replacement ecu. With OBD II cars, folks that need to pass emissions testing will need to install the factory ecu at testing time.
