Is VVT worth it Miata?

It’s definitely the best option for naturally aspirated power IF you have a way to control it. For boost, the VVT doesn’t help but all NB heads are superior to NA heads. If you’re planning to boost the car, remember that a high compression engine will have better response but will ultimately not make as much power.

How reliable are mx5 engines?

The reliability It shouldn’t be a cause for concern – MX-5s are very reliable indeed. Engine woes are few. The very earliest cars, from 1990-1991, have the potential for engine failure due to problems with the crankshaft pulley bolt.

What is mx5 VVT?

Mazdas VVT is just variable cam timing on the inlet, doesn’t really do anything for peak power like Honda’s VTEC system, which alters both cam timing and valve lift. The MK2.5 engine has a 0.5point higher compression ratio, a better flowing intake manifold, and a MBSP which helps reduce crank flex at higher RPMs.

Can you turbo a VVT engine?

In general, modern variable valve timing can adjust the volumetric efficiency of your engine by RPM and load. But, with newer turbochargers that are more efficient and have bigger turbine housings, it is possible to tune VVT in a similar way as you would a naturally aspirated engine.

What goes wrong with Mazda mx5?

Rust is, by far and away, the MX-5’s biggest enemy. The most likely locations to suffer from rust are the rocker panels and the fender arches. ‘NB’ generation Miatas are prone to front frame rail rust as well, although it’s not a wide-spread problem compared to the other two locations.

Are old Mazda mx5 reliable?

Most Reliable New Car. Monday, said: ‘Most people probably wouldn’t associate iconic sports cars with reliability, but our research has revealed that of cars aged 0-3 years old, the Mazda MX-5 is the most dependable new car, with very few owners reporting any faults and no breakdowns at all.

How does mx5 VVT work?

It reads engine RPM, air intake and coolant temperature to give the optimal control of valve timing. If there is failure in the electrical input to the OCV, the OCV rotates to its maximum retard position. The engine continues to run just fine but it’ll have lost some of its Zoom-Zoom.

Is bp4w a VVT?

The bp4w head has larger ports than the earlier engines, making it a good upgrade for a turbo car. Bp6d is a vvt head which makes tuning/swapping more complicated. The vvt engines do have higher compression, which would be a bonus if you’re staying na.

Does a 99 Miata have VVT?

On the 99-00 it was 9 to 1, and was increased to 9.5 to 1 on the vvt engines.

What is advanced cam timing?

A Basic Overview of Cam Timing To advance or retard a camshaft is to change the alignment between the camshaft and the crankshaft. Advancing or retarding the cam pushes the centerline of the camshaft to one side or the other of the crankshaft centerline.

Is the new Mazda MX-5 a reliable car?

The new Mazda MX-5 Miata is, well, new, so TrueDelta has no reliability data on it. But past Miatas have all been reliable, and other current Mazdas have been reliable, so there’s little reason to think that the new Miata won’t be.

Is there a VVT swap for a Mazda MX-5?

Mazda MX-5 VVT Swap. The VVT swap is a common upgrade for the early Mk1 and Mk2 MX-5s. Allowing you to take advantage of the later 2001-2005 1.8 NBFL VVT Engine, which boasts well for an NA power gain (not so for turbocharging, due to weaker rods when crossing the 230/ft/lbs reported limit).

Which is better Mazda MX5 Mk2 or 2.5?

Mk2 RS has some trick cams and a higher compression ratio IRC, it’s a genuine 160bhp. The MK2.5 motor is give or take a few the same peak output as the MK2 engine, but it’s area under the curve is much fatter.

How much horsepower does a Mazda MX 5 have?

(WTRQ = Wheel Torque, ETRQ = Engine Torque, WHP = Wheel Horsepower, BHP = Engine Horsepower) – BHP is a calculated value if your tuner only provides this value air on the side of caution (the lower value). The block is a closed deck design made of Iron, it’s incredibly strong and have been known to take over 500BHP. The 1.8VVT Block is stronger.
