Got a lot la. Find out if it's a billet or regrind cam. Always opt for Billet. Last time I installed the 260/280 Pipercams on my car and that's a pretty mild cam. Slightly broadened the power band and with the adjustable cam pulley I could shift the powerband higher or lower. The beauty of SOHC and self adapting ECUs. I don't know if they had any other variant of Siemens VDOs though. I still recommend you go for a stand-alone.The one I see is this

other then that I think all are 280 & 288 degree.
Powerzone I recall are regrind cams which means they take the stock cam and grind them to their specs. Billet cams are built out of one piece to make the cams. Personally if you need to add washer or whatever I wouldn't take the cam. Mine were direct plug and play.
The crank pulley you are looking at is wrong la.Crank pulley

After what you say and I think throught. In JB here I don't have a mechanic that is really skilled in doing this kind of mods.
If there is the case I think I might juz give up on this and changing the extractor since is kinda rusty .Hahahaha
This is the crank pulley you wanna buy :
This is the Siemens VDO stock pulley :
Do you notice anything different?
YES. The Siemens VDO pulley has an additional gear attached to the back of the pulley for the crank angle sensor which the Mitsubishi 4G15 doesn't have. The one you wanted to buy was the MMC crank pulley.
Also this is what a proper lightened crank pulley should look like. This is from a good brand Fluidampr which is kinda expensive :
It has a dampening layer which absorbs the shock and vibrations that the pulley is subjected to. The middle sleeve needs to be reinforced too if you don't have some sort of harmonic damper, otherwise the shape of the middle hole will deform and you'll see problems 2-3 years down the road depending on how you drive. Wobbly pulleys are a thing.
If you look at the now defunct mythelogy brand, right in the center the hole is reinforced with a steel sleeve, the rest is lightweight alu and there's a rubber dampener there that supposedly absorbs some of the vibration. There's a lot of debate as to whether it really works or not for Mythelogy pulleys but personally I've changed so many pulleys in my old Wira it's not even funny.
Where is your exhaust 2.5" ? The tip or the piping diameter? 2.5 is a little large and personally I feel 2" is ideal but 2.5" isn't going to ruin anything as long as it's straight flow and your extractor is good. Personally I recommend a 4-2-1 setup for a wira manual. The original Wira SE extractor was actually a well built extractor but you'll be hard pressed to find a good condition one at this time so if you do get an extractor consider a properly tuned one not just any extractor off Shopee or Lazada unless you know what you're looking for.Wira uodate
Another thing I juz found out. The exhaust is 2.5 inch. Is this normal for 1.5 wira? Or is it too big?
