JUN High Lift Exhaust Camshafts has be released

indyn

the claimed stock numbers might be different for Japanese market. Don't they have different gas/petrol octane ratings giving them more HP and no emissions.

18 whp is not bad, need to finds someone experienced to swap the cams.

they responded more on the VVEL, but as much as it sounds exciting, rather be skeptical about it. On the other hand, these are released by JUN, a respected and proven performance aftermarket tuner.



- Is this using ECU tuning or making mechanical changes to VVEL?

We already analyzed Nissan ECU VVEL mappings.

More than 450 Rear wheel HP, we have to make the VVEL intake camshaft from scratch.

Under 450 HP, mechanical VVEL modification is not required.

- Is this on stock car or with combination of headers, straight pipes or any other modifications?

As you see, the stock header , cat pipe and tail pipe is very bad for big HP.

If you change just EX camshafts, not so effective.
