rs25.com usually has some used ones for a really good price. I picked up some Delta 2000 cams for 165 shipped.

But you can contact Delta and they have a few regrinds available.

I hear everyone talking about delta cams. How are they in comparison to the cams from rallitek? Because I was going to go with them but I really never hear much about the rallitek ones.

I believe the Deltas are cheaper. I know with Delta, they send you a camshaft that has been "reground," as in someone sent them a camshaft and they changed it's profile. I don't know if this is how rallitek does it too.

i honestly have no idea...
im starting to do some extensive research...
im losing my license thursday. so since my car is going to see about 11 months of down time i figure it would be a great time to build my 25TSL.N/A to a 2.5TSL.Turbo.

any info from anyone else would be great!

how do you "regrind" something to give it as bigger rise or duration? it would only make it smaller...im confused and in the dark

someone show me the light! lol

oh ok, i see.

so do you give them the specs of the rise and duration and they do it that way or do they have set specs and sell them that way only?

When regrinding Subaru cams, they typically take material off the BASE CIRCLE, which effectively increases the lift, but requires the valve clearances to be readjusted. The duration can be manipulated as well by altering the profile.

Some cams (EJ25D for instance) need to have the base circle left alone to keep from having to replace the shims for correct valve clearance. On these, they weld material onto the existing lobes and grind them back down to the correct profile.

Delta has a youtube channel illustrating the process quite clearly.

You want the 1000 Grind, not the 2000 Grind.

Is $160 a good deal now? I think I paid about that when I had my 1000s made and that was full price.

You said you were going the turbo route? Maybe you should ask for a forced induction type cam. I believe the profiles are a little different from N/A to F/I.

The 2K grind is a little more aggressive.

From what I understand:

-The Rallitek cams are very very similar in every aspect (including method of manufacture). The difference is the price. Don't quote me, because I've never seen both at the same time, but that's my understanding from my research.

-For my EJ22, Delta (at the time) had 2 grinds. I went for the one that moves the power to the lower RPMs. It's pretty nuts to get power at 1200RPM. If you search, some pretty widely respected NA gurus will recommend that grind for 95% of the people on this site for a variety of reasons. Heck, maybe even 99% of the people on this site.

Where the power band is. The 1000's produce a fun powerband within the stock rev limit that works for everyday driving and for giving it hell on the weekends. The 2000's produce a powerband that necessitates raising the rev limit to get much of anything out of the cams and is too high for street use.

Would you say that people with decent headwork could get some gains out of the 2000s, but everyone else should probably stick with the 1000s?

what is 'too high' for street use? the stock cams dont make any power past 4k and it sucks. i drive my car hard and would rather make more power up top than down low.

Good headwork would help either cam. The real issue is how fast do you want to spin your engine before it makes power. If you want to stick with the stock valvesprings and the stock redline, you need to use the 1000s. If you're willing up upgrade to the Supertech valvesprings and retainers (probably $700+ retail, plus install) and raise the rev limit 1000RPM+ over stock and have to spin it that high to get it to do anything, then you run the 2000s.

When I had the 2000s in, I made nothing (as in less than stock) until almost 5000RPM and had to spin the car to 7000RPM every day to get it to go anywhere. With the 1000s in, I make stock below 4000RPM and significantly above stock from 4000RPM to 7000RPM.

Thanks. Don't get me wrong. I'm sticking with the 1000s I have. I'm very happy with them since I don't feel any need to win some horsepower/dyno battle at 7,000RPM. Jerking my head back at 1,500RPM from all the torque is more my style

Hi everyone,

I have a 96 impreza 2.2 and have been thinking of doing 11:1 pistons over the stock 9:1 along with some possible light weight rods just for kicks. Then doing some port and polish in the heads and intake with some delta 1000 grind cams. Then getting a better intake along with a good header and a high flow cat as I still want to be legal

Now my problem is trying to figure out how to tune my car since it is a 2nd generation car with a maf based system

You can get an apexi AFC controller. That will help with fuel and air. In order to do timing you would need something with more features like a Ralitek P6 or an Emanage.
