Dura Tech Camshaft/Valve Spring Installation

Changing the stock valve springs to racing valve spring (more durable)

Dura Tech valve springs installation (it took more than 2 hours to install this as it requires special tools so that there wont be any damage to the valves)

Sadly, i forgot to snap the picture during the camshaft installation, as i went somewhere, the process of installing the camshaft and the valve springs alone took more than 3 hours. The mechanic responsible for this installation is Mr Jai of Powerzone.

Idling and revving sound from my 4g91 with Dura Tech Camshaft. Enjoy!

Dura Tech Racing Camshaft

Dura Tech Racing Camshaft is a product from USA. And according to the specification for 4g9x engines, the spec is somewhat similar to Jun spec which is:-

IN: 272 deg, 10.85 lift
EX:272 deg, 10.85 lift

The price in the market varies from rm2***++ inclusive of valve spring

All i can say is that this camshaft is affordable, good quality for people who wants to upgrade their engine and yes, the horsepower is really nice.

I will update pictures of installation and dyno sheets in the coming time :)
