B6T 323 GTX Camshaft?
I would get original 323 GTX 1,6i Turbo camshaft.
I have an 1.6er Miata Turbo.
Is there a big different between the Turbo camshaft from the gtx and the 1.6er Miata Camshaft? Are the GTX Camshafts a little bit better?
Could someone give me an advice?

WAY less overlap, better for boost for sure.

looks like the intake cam might be the same (however the lift may be different), the difference is the exhaust valve opens a little sooner in the cycle but closes sooner as well.
freaking third time I've used that link today already.

This also means that both cams are retarded compared to the B6T setup, which can be advantageous at higher rpms.

B6T
1,597 cc (1.597 L; 97.5 cu in) B6T - (78x83.6 mm) - The ubiquitous turbocharged, fuel-injected and intercooled 16-valve DOHC B6, released in 1985 and used in numerous models worldwide including the 323 GT-X, 1985-1989 Mazda Familia GT-X/GT, 1985-1989 Ford Laser TX3 turbo, and later Mercury Capri's. This engine was most commonly found mated to a 4WD drivetrain although FWD models were also available in the capri XR2 & 323 GT.
Power and torque outputs varied across markets due to emission and fuel standards.
The B6T available in north america came with 132 hp (98 kW) & 136 lb·ft (184 N·m)
The Japanese version of the B6T was the most powerful, producing 147 hp (110 kW) and 137 lb·ft (186 N·m) due to better intake manifold & ecu tuning for better gasoline 95 octane
