New Rims!

I've decided to change to a new set of rims, TE37 replica. Downgrade from 16" inch to 15" inch, from 7jj to 6.5jj.

 

 

The tyres are Yokohama C-Drive which also outperformed by my previous Yokohama A-Drive R1 which handles better.

All i can say, it is much lighter than my previous rims. Improve my acceleration, but the downside, i lost some of handling abilities due to smaller tyres and smaller width which reduce traction.

Already feel bored with these rims after a while, guess i made a wrong decision.

E-manage/Dyno

I've selected E-manage from M7 (complete with ignition harness)
Installation by Mr Jai from Powerzone

 

 

  

 Prepare to dyno at Powerzone, using DynoJet. Tuned by e-manage, tuning done by Mr Jai.

As a result of this upgrade, this originally near to stock 4g91 with camshaft and e-manage tuning managed to get an additional 25whp. With stock injectors, and yes, stock ecu with no rev cut. Next upgrade will be ecu rechipped and add larger injectors to support fuel and to meet the powerband of the camshaft which is currently at 3500rpm to 7500rpm, however the rev cut at 6700rpm eliminates the power peak. Hope to get more 10whp after this later upgrades. Til then, cheers! :)

 

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.
