The stage 2 felt no better than the K cam I took out for it. The stage 3 is more worthwhile.

I worked so hard to get my stage I cam in that last group buy, you're making me sad. Are there no justifiably satisfied customers?

Satisfaction is a relative term. In the redblock world, most people are satisfied with having an aftermarket part, regardless if that part operates ideally or not. For such a limited market, most people can't absorb the cost of development to make things better because people aren't willing to pay for it.

The RSI stage II cam has potential in a very narrow range of builds, likely developed around one of their specific engine builds. Unfortunately, it doesn't suit the common upgrade path very well. That's my beef with it. And since they're willing to reveal very little about even the basic criteria of properly utiliing this cam for fear of "releasing manufacturing information" there's no way to actually use the part for what it was designed for.

To that extent, the redblock I'm working with now left a customer very unsatisfied because the operating characteristics of a cam advertised as seemingly mild had a powerband that was only usable in the last 500 rpm of the rev range.

Isn't the stage 2 similar to th KG2T? Seems like a lot of people have had success with the KG2T.

Post up specs of both. Valve opening / closing events, intake centerline, lobe separation. You know, stuff that matters when specifying a cam.

Oh wait......

From RSI's site before things went under

RSI Stage II Camshaft

The RSI Stage II turbo camshaft was designed with broad power in mind, it works great with stock valvetrain and will rev reliably to 6800RPM.

The Stage II cam works great with moderate to wild mods and works well in the 270whp-420whp range. Our Stage II camshaft is a dual pattern cam with a larger lobe on the exhaust side as a means to help counterbalance the disproportionately small exhaust valve/flow in our 8v heads.

This is a cam for 2.3L or more. Needs to really breath. We highly recommend a header and larger turbo to really take advantage of this cam. This cam is not suitable for daily driven automatics as this cam really turns on at 3000+ RPM. This cam works great with stock valvetrain to 6800RPM.

Intake Lift: 11.38mm
Intake Duration: 238 degrees at .020"
Exhaust Lift: 11.96mm
Exhaust Duration: 270 degrees at .020"
Lobe separation: 116 degrees

This means: "KG2T - TURBO cam for turbo use.
Increases torque at low rpm´s - clearly noticable in
city/heavy traffic situations. Also an increase in torque at
mid to high rpm. Revs more freely."

Cam data: Intake lift 10.5mm (0.413")
Exhaust lift 11.9mm (0.469")
Nock angle 114 degrees
Duration 300 degrees

Yup, that's all we have to work with. No real spec sheet for each cam I guess.

Then how can you claim they're similar?

Heres the sheet that comes with a kg2t. I didn't even receive it when I got one from a group buy, but got this image from another user. It gives an installation angle at least.

To get mine to the position they specify on a block/head that was cut ~.010" and a stock headgasket, I had to advance the cam ~13° (over one full tooth).

Wait, so there's a spec for how to set the cam and make sure it's actually at TDC? Damn. lol

Spent a lot of time trying to find any kind of specs for the IPD cam since I didn't get any form of cam card with it, finally found something on the Enem site, buried. RSI is not alone with not providing info on their cams.

O hello everyone. Yes, the RSI 2 is on its way out.

Looks like trying to sell it here will be pointless now...

Hey Sparkles
I also got the stage I cam in the gb and I like it over the standard cam that was in there before. Decided to be sensible for once & not get the stage II to keep a more usable rev range.
Wagon is a dd, with other mods, I'm running the cam 4 degrees advanced.

Just an FYI for those reading this thread.
The IPD Turbo cam, same as the Enem V15 Turbo cam, is set at TDC with #1 intake 1.0mm open at TDC. Took some digging to get all the needed info, figured I'd save some people some research time.

Set mine to 1* advanced over that, really does run quite nice, might bump it 1 more and leave it at that, we'll see.
