Being a noob and everything, I've been seriously considering cams for my 98 2.5 DOHC, and already have an e-bay intake, IM Spacers, StreetLite flywheel going in and stock exhaust for now (thinking OBX EL Headers). I REALLY don't have the $$$ for a separate engine management system nor the knowledge on how to use it (yeah I know, dyno day, but too far away for me). Do you have to have separate EM with cams? Also, how much torque loss with the 2000 over 1000?

No, DLC has cobb cams and basically every other bolt on you can have on the car and he has no EM and runs perfectly fine. You'll still have CEL though.

Engine Management is not required for Cams. BUT.......

I've been doing a lot of logging of my car. I'm not a tuner and just starting to look at what I'm getting on my logs. It appears to me that the ECU programing from subaru is missing out on a lot of HP/TQ. So by putting Cams in, we may not be seeing the gains that we could if we could go in and change some stuff in the ECU (wich only 05+ can).

So I think if you are going to be modding and want to get every penny worth, Piggyback or even stand alone EM would be something that you invest in. May not be one of the first, but maybe down the line.

Good to know and thanks for the info. EM is on the "eventually" list along with other non-engine related mods. I just wanted to see if I could get away with running cams for X amount of time before going EM, or if I had to do them together.

Why do you have two graphs for each cam which show different amounts of lift?

Wow, been a long time since I had looked at this post I did. To answer your question williaty, one set of graphs are for the actual CAM lift, where as the other set is the actual VALVE lift (these graphs show the RAR at top that was used).

Still working on figuring out the exact RAR on the subaru, I've found at least 4different ones listed. Finally got a spare motor and just need to finish determine that.

I know this is an old post but I have the Cobb "Spicy" cams in my car and I don't believe they are all that aggresive in comparison to Delta 2000.

Unfortunately, Web Camshafts only has specs on their 148e cams posted on their website.

Here's the specs for 148e: Web Cam 148e

The Cobb "Spicy" cams were manufactured by Web and are equivalent to the 115 grind, which were more aggresive than the 148e's.

My cams even have a "Web 115" stamped into them.

I wish I had more info on them, but I even emailed Cobb awhile back and they had little archived information.

shot delta an email off hoping to get the profiles for the 1500 and 1000/2000 cams up as well.

having an SC'd setup i'm having a little more difficult time concluding which are the most suited. so far as i can tell i want the intake profile from the 1000 with the exhaust from the 1000 but retarded a little, but haven't seen the 1500's to do a comparison.

sigh. this would be so much easier if i was DOHC.

Okay, while searching I found some apparent specs for the Web 115:
Duration @ 0.050" 224 degrees
Intake Lift 0.410"
Exhaust Lift 0.350"

That compares to the Web 148e:
Duration @ 0.050" 208 degrees
Intake Lift 0.410"
Exhaust Lift 0.355"

The 115 has slightly less exhaust lift and a longer duration, very similar to the comparo between Delta 1000 & 2000.

So, that graft in the first post is pretty cool! But, has someone looked at the difference between the delta 2000's and the delta 3000's? Looking at building a higher revving NA like 7500-8500 rpms so any info for the difference between the two would help!

I doubt it. They are not designed for positive manifold pressure.

as long as it's SOHC it uses the same cams.

if it's DOHC, they do "220" and "230" etc cams, which you'll need to ask them about.

SOHC, but the 253 engine camshafts are different because of the AVLS system.

sorry, i should rephrase: the same grinds. i don't believe the grinds differ at all between the various SOHC engines. there's nothing getting in the way or whatever of delta's grinding wheel.
