Cam shaft, as long as you buy from reputable you are safe.

Maybe not too fierce duration, cos the car may not idle too well.

 

As for port & polish, it is to reduce the air intake flow friction losses (smoothen the flow and increase the flow vol). So if it is not done properly, it may be even detrimental.

You what car?

My old Alfa cams from C&B cost me almost S$1k couple years back.

Installation was couple hundreds ......Crosby Motorsport.

The piggy ECU cost S$600. Dyno tuning couple hundred again.

 

As for port and polish, I believe the same shop does the same.

But mileage differs from car to car. Don't have too much expectations.

You may be better off installing a LP Turbo.

hmm... im driving a wira.

my mech is actually doing for me my port & polish and modified camshaft for $850.

As for ECU, will be changing from semiens ecu to mmc one after the above is done.

 

LP turbo is nice but i stil prefer to play with NA. Perhaps maybe after few yrs later then swap a vr4 engine in. [sly]

yeah... vr4 with turbo is damn fast... have even tried a vr4 with twin turbo and 8 Fuel Injection...

really [sweatdrop][sweatdrop][sweatdrop]

 

The prob is because of light chasis.

 

If i were to put in a vr4, i dun think i will be going to turbo it becos i prefer NA [;)]

there r suppose to hav diff stage of camshaft...

if the lift of the cam is too high,u need to change those valve,valvespring n retainers...for a single cam engine(1 cam) plus PnP plus those valve spring...

shd be abt $1600-$1800 n cost more for twin cam(2cams)...

$850 is consider quite cheap for changing cam n PnP...

maybe its a stage 2 cam with not so high lift so ur valvespring n retainers need not change...
