Default question for the OG NA guys

Yesterday I took the RS to Raceway park in NJ. Ran a 15.7 at 88 MPH. Here is the thing, The car is a 98RS with delta cams. 13.4lbs flywheel. light weight crank pulley and K&N drop in with borla headers and a stromung track pipe to a stromung catback. The car is tuned with an S-AFC neo. my 60 foots were junk since I am running on blown struts right now But I couldn't help wondering if getting a Greddy E-manage would help out. especially with the ignition timing, which I would like to advance slightly for the cams. A good friend of mine works at a shop in CT where he tunes mostly everything, mainly subies tho, he was saying if the E-manage was worth it he could build a nice map for the car. So that brings me back to the question. is it really worth it?

What kinda of gains would make it "worth it" for you from a cost standpoint? I personally wouldn't consider it worth it to gain a couple hp here and there. I spent a lot of time and money trying to make my old 05 RS fast and at the end of the day there's no cost effective way to do it. I had a ton of fun on my rs and it was great to beat on and rip around with. If you looking for power out of a subaru though, i'd start looking into forced induction.

if you really want to dial it in... I would say go for it.. but you have to think cost effective.. if your going to stay NA and keeping the car I would go for it because you could handle jsut about anything you can throw at it within reason.. and if you keep going you will have to tune anyways..

At a cost of 200 bucks with everything included cost really isn't a problem. I guess I will go ahead and buy it then and see how it goes. Thanks for the help guys

Is it a phase 1 or 2? I have a phase 1 with the same setup, minus the cams and flywhee, but with ported heads and a PP6 (butt-dyno, datalogging tuned).

I ran the exact same numbers at Lebanon Valley...I mean exact.

Timing adjustments on the PP6 never really helped me...Fueling made the most difference.

I'm guessing a good timing and fuel tune, especially with your cams, will give you a 1/2 second and 5-7 mph.

All speculation of course...

Good luck!

This.

Can a real piggy back (or even better, a stand alone) get more out of your hardware than your current SAFC? Hell yes, that thing is a kludge. You won't get anything major out of it though. You're looking at a couple of foot pounds of torque here and there and that's about it.

The only thing I've ever done to the car that really made it considerably more powerful was the Techworks Engineering 4-2-1 HighOutput EL headers. If you want to go faster, get a set.
