Agreed on the lightweight crank pulley part
Not to mention normal drivability suffer(A/C Not Cold,Engine easier to stall etc)

simple..

1) you own a workshop
2)ive never heard a bad review of your services means you know your shit and you do a good job.in fact before you even quota a price you always ajak ppl over to discuss what needs to be done and have a look at ur workmanship.

do you dare vouch for the quality of products you dont carry or the services of any other workshop?

Also,some well known 4G63 master refer Eric Hsu as Tooner

True. So that they can afford to fund engineers who thinks their funders are stupid.

I think his argument is that if these aren't reliable, why do big names make them. The reality is that big names will just as easily skimp on the risk if they feel that there's enough money to be made. If companies can put melamine into baby formulas, well, you get where I'm going lol. After all, caveat emptor 

Always assume worst case scenario, that way you'll always be ahead of things. For your friend's Airtrek, I can bring up a Evo 9 that had a cam pulley failure that resulted in total valve loss, but of course that was a bred monster of 500 HP. Even mine runs 380 HP with RON98 which is way outta spec. This is an even bigger issue with blocks where the bore versus stroke isn't square, where the effects of harmonics stack up with that of the velocity of the pistons. As a process eng once told me, that piss you take into the sea may turn into that tsunami that wrecks some dude's house.

My assumption is that if you're going to get an LCP to gain more power, you're not only increasing the stress on the engine by introducing more power, but you're taking away something that decreases stress. In high performance scenarios, the usual is to toughen up the crank pulley while lightening the cam pulleys, so in a way it goes against the way I figured things should be done, hence the bias.

Probably just me being anal lah. I mean my car has lab cal-ed torque wrench and a set of torque drivers to fit everything up. It just bothers me because I feel that there are many places to get more evident and effective power out 

1. Now do you seriously believe that companies don't take risk for money? . There are first version big brake kits out there from big names that screw so badly with the ABS systems the cars are undrivable. During my younger days, I used to drive a P38 Rangy, man that shit BECM and security system was bugged to hell, using your logic, would Range Rover build a shit car and done more testing?

2. I don't live in Malaysia. And I base it on trust that a man who spends a crapload of his money on cars would try very hard to make sure what he got was genuine. Maybe it was the mechanic's fault, maybe it was fake, but when a lot of people say the same thing. Well, err on the side of caution.

3. Mitsubishi in the UK makes the FQ400, 400 horsies. From the factory. . Aslo available in the FQ-300 and FQ-360 flavours. Also from the factory. I'm keen to hear your argument in regards to this

4. I'm not sure how you can equate a torque wrench to a feeler gauge, they measure different things.
