Advice about the Camshaft

Greetings to all, my wife and I just purchased a 2008 Mini Cooper S, and let me tell you, it is truly a remarkable vehicle.

It was the usual release of the timing chain guide that kissed the piston and shattered it. Along with all that exciting things, there was also the matter of the head being left in the trunk and the cam lobes corroding. It seems like I might as well update the cams if I have to regrind or replace them anyhow. Do you think the Newman Cams are an improvement? By the way, is an improvement to the intercooler necessary? For now, I'm only using a stock replacement, but I'm prepared to improve it if needed. In addition, I upgraded it with a Borla exhaust system and an AEM cold air box intake.


The assistance you can provide is highly valued. I only want to give it a little more energy, so I won't be taking it racing.

Thank you!

Using original equipment manufacturer (OEM) camshafts should be sufficient when updating the camshafts. regardless of the brand. The N18 9.5 to 1 pistons are a minimum need for any aftermarket modifications. As a result, the compression ratio will change from 10.5 to 1 to 9.5 to 1, which will alter the quelch and need remapping the computer, which will disable some codes. you'll simply need to be aware of what's happening because, as issues develop in the future, you might not be able to retrieve codes. for the sake of the mini cooper, which is, in my view, a coin toss. If the computers on board are in good functioning order, then chances are 70 percent that you will be able to tell what's going on and 30 percent that you won't be able to tell because it won't be generating any codes. Prior to purchasing a new set of camshafts, make sure to closely observe the lift and duration numbers. Certain valves necessitate shims, while others call for distinct valves to be compatible with the camshaft. Rick probably doesn't. however, live webcams do. To get some things going, you need to disable the engine's electronic gas regulator (EGR) and lock the vanos actuator. In my personal view, it would be best to hire a professional installation or at least schedule a dyno session after the installation to have them fix any other issues. In addition, you might need a low-level gasoline pump.
To clean those cams, wouldn't you simply use a dremel with the right plastic Scotchbrite pad polishing pads and compounds?

I don't think so. They're very roached. Well, I'll just drop it off at the machine shop and see what he says. Doing so would be a huge mistake on my part. I'm not interested in going down that rabbit hole with this vehicle since I've built a lot of performance engines and know how deep it can go. I will find a way to make it work. Great, I appreciate it!

Whatever the case may be, N14 engines are becoming increasingly rare. The amount. In the United States, the secondhand engine has a part-out value of about $4,000. You might compare it to the ever-increasing price of silver. I have had mine since the tail end of 2009, and around five years later, when the engine recalls started rolling in, the price for a short block and cylinder head was around 700. Back then, the only genuine game they would play was 300 for the cradle. has a value of 1500. and a pre-owned second-generation Mini was likewise priced at under $1500.
