cool man all mivec kaki here....

dude how much u bought ur 306 matspeed high cam?
and how ur pickup using 4-1 dude?

 

[chempiang_9]

i bought the cam for rm1600... "2nd hand".
there should be a lot of different when you are using 4-1s..
since i'm using hi-cam.. my mid n high range much more improve, but there's lack on low range.. so by using 4-1s.. can cover the lack due to hi-cam...
sorry bad english.. hope you understand.. chill:_:

Hey Shaun27 its always great to see 4G93 brothers around! I am not pomen/sifu or anything just passerby and happen to be a Gti mivec user trying to encourage our new brothers

Make sure your tuner know what he is doing and he can advise you all the 4G93 mivec hybrid details! From your list if you dont have mivec half cut then you need more stuff, I assume your setup will based on Mivec Wiring & ECU, and perform optimum setup just to hit the road (save hardcore for others) such as:

Mivec Map sensor (oem)
Mivec Intake Manifold (oem)
Mivec 60mm Throttle Body (oem)
275cc injectors (perdana)
Fuel Regulator (sard etc)
Higher Rate Fuel Pump (Walbro, Aishan, etc)
Mivec Solenoid and complete harness without cutting (oem)
ACL Race Bearing
4G92 DOCH 1.6 OEM Piston (or Mivec Dome Piston for extreme compression)
Metal Gasket (1.5mm if you go for Mivec Piston)
Spark Plug Wire for Mivec (HKS)
NGK Iriway 7 or Denso IK22 sparkplugs
Rechip ECU (remove 180kmh speed cut and remap ecu)

There are plenty of resources online you can refer to, just to name a few:
MIVEC Owners Group
tacra's diy garage: Search results for mivec
. Rotation / Minute .

Hope these help
