Oh yes, we have the following for the 4G92 SOHC/DOHC:

1. Tuned length extractor kit=RM450 installed
2. Hi-performance road formula camshaft at SOHC=RM1250, DOHC=RM1800 (installed with exchange)
3. Ported head =RM1800 (installed + exchange)

Regards.

if we would to change the camshaft, do we need to get a adjustable am pulley as well ??

 

[Powerzone]

That's not necessary as all our cams are ground with the original index (pin/slot on the cam front end) as the starting point. So with the standard pulley it's already spot on! No messy, difficult (unless done by experts), and time consuming "dialing in." (Although we do provide this service, but only for difficult cams from somewhere else.)

may i know a rough figure on how much hp gain for port and polish on 4g92P auto? thanks... :)

About 10% is achieveable. However, with a performance cam & extractor the gain from P&P is higher. This is because we need a better volumetric efficiency (VE) first (with cam & extractor) before we get rid of bottlenecks in the standard cyl. head.
