BC cams with a 14b?!?!?!?!?!?!

[Thumper32k]

Just wondering if anyone has any experience with this setup or has any advice? I plan on upgrading my turbo but its not in the near future.

PS I'll be using BC 272's

I don't have any experience with BC 272/272's but I got a smoking deal on a set of HKS 264/272 cams. I debated whether or not to install them, as I'm still running the stock 14b. However, many posts I've read suggested that I would not see a noticeable decrease in performance, but I would notice a slight gain. Based on my research, I decided to go ahead and install them and could not be happier that I did.

In one word- Amazing! I could not believe what a difference the cams made. Before the install, the engine would run out of steam between 5K-6K rpm. Now it pulls strong and steady all the way to redline (7K rpm). Keep in mind that I already had many of the supporting mods done- 190 fuel pump, rewire, ported 2g exhaust manifold, 3" turbo back exhaust, AFPR, UICP with 2g TB elbow. The turbo is unported and I run 17psi with no creep on a home made manual boost controller. Without the intake and exhaust mods I don't think I would have noticed as much of an increase.

Also, take into consderation that the 272's will raise your powerband higher in the rpm range which could (and probably will) put it out of the 14b's optimum efficiency range. I went with 264/272 to retain a more streetable powerband on the stock 14b and even the 16g upgrades.

how much slower spool are we talking about and how much top end power would i gain?

When I bought my new head for my 1g the guy forgot it came with 272s and i used to have the 14b and at first I thought the head was messed up cus the idle sucked really bad but when I found out it was the cams and actually started driving alot (that plus just put the evo 3 turbo on there) ive noticed an insane amount of difference on my rally car. but those also arnt my only mods. but I would suggest not get cams unless you wanna idle like shit and it can be annoying at times.

A bigger turbo would be a better choice for the money, unless you're really in love with a 14B for some reason.

Don't think cams magically unlock horsepower, and don't assume that "bigger is better" when it comes to cam selection. HKS 264's have allowed a 16G-powered 1G to run a 10.33. http://www.dsmtuners.com/forums/drag-strip/262203-new-evo-iii-16g-record-et-no-no2.html

I personally wouldn't waste my money on 264's since the factory cams in the Evo 9 are 256 / 260. However Mitsubishi put those cams in from the factory to enhance the performance of the factory turbo. If your future mods include a turbo that's bigger than a 16G I would advise at least 272's or maybe even 280's. But you also have to take in to consideration the purpose of the car. If you want to stay with a 2.0 rather than stroking it your powerband could very easily get up to 9,000 RPM or maybe more. And that's where the 280's would really sing. However if you want good power around town lower in the RPM band and your future mods include nothing bigger than a 16G, you might be happy with only 264's.

Either way upgrading your cams from stock is NEVER a bad idea unless you need to pass a smog test like we have in California. Have fun bro.

Evo 9's also have MIVEC, which throws any advertised cam durations out the window depending on RPM.

The purpose of my post was to show that 264's have run 10's when coupled to a 16G....anyone needing more airflow than that needs a bigger turbo instead of bigger cams.

Dan is #12 on dsmtimes.org and Joe Bucci is still the record holder for fastest 14b with and with out nitrous.

Dan has a VERY streetable car though. He has the highest HP based on weight and trap speed. The next highest trap speed was 3mph less and still with a 200lbs lighter car.
