Cams?

jgheels2003 · 11-03-2005, 06:38 AM

Is anyone hearing anything about cam upgrades for STIs? Or, if there is anything on the horizon that won't cost a fortune and will make good power?

Cam upgrades and better heads will always help and are available. As I am sure you aware it is a costly proposition to install them though....

Money well spent. Figure on about 2 grand to buy them and have them installed.

Will do more for the overall performance than a "next step up" turbo upgrade.

A 2.0 WRX made 300whp at 12PSI on a vf34 with cams, think about what that means a VF39 could do on a 2.5 with them....

are there any cams out there that keep the AVCS though?

and while you have the heads out you mine as well have them ported too.

Yeah, aren't there DPR cams that are still AVCS capable?

I just had to ask about this. Even though the 4g63 is much different than our setup look what those cam upgrades do while keeping everything else pretty much the same.

I figured it would be costly for an STi and I can't imagine its an easy install, but looking at what they can do to a WRX from Daves example (EVOS obviously have this in the bag) it seems like the missing link. I shouldn't even entertain the idea before building up the internals though....

Yep, DPR cams are AVCS capable.

How much are they? Anybody has a set of cams on their car?

I had Crower stage 2 cams in my 2.5 hybrid WRX motor. The powerband was a big wide flat table. Power from 2500 to redline. I was running 7PSI on my vf22, it pulled harder than when the car made 309whp@21PSI on the 2.0.

These were non avcs cams, $890 shipped.

IIRC the avcs cams are like 1400ish?? Install is in the 600-600 range.
Pulling the motor wouldnt be out of the question for the install, but you can probably get them in with it in the car.

I just checked DPRs website, it looks like Cams are 1145, plus they recomend there valves and retainers (another 380).

Stage 1 cams can use the stock valvetrain

UA_STI · 11-03-2005, 10:19 AM

I wish somebody actually had these, so we could see some results.

JJ18Sniper · 11-03-2005, 10:25 AM

It would be nice to see some sort of experience with these installed... it's only a matter of time
