PhilT Posted April 2, 2008 Share Posted April 2, 2008 How much power you looking to squeeze out of that 2.5i ? Double Award Winning Legacy GT Wagon Link to comment Share on other sites More sharing options...
violhence Posted April 2, 2008 Share Posted April 2, 2008 Do these really fit on a NA engine and actually improve HP? Link to comment Share on other sites More sharing options...
Brad023 Posted April 2, 2008 Author Share Posted April 2, 2008 I'm looking to get as much as i can until i do a motor swap. with headers full exhaust, intake, and piggy back ecu. i Think it is like 50-60 hp xcceleration.com said that Link to comment Share on other sites More sharing options...
terrangama Posted April 2, 2008 Share Posted April 2, 2008 from my experience, at least with my GT, is that cams dont really add so much power, but rather keep power flowing consistently at higher rpms. Again this is only what I know of the turbo engines, I have no idea what it would do on n/a Link to comment Share on other sites More sharing options...
808subaru Posted April 2, 2008 Share Posted April 2, 2008 TWE makes quality stuff. My buddy used their parts to build his impreza to a d street prepared champ car. They make good internals. Link to comment Share on other sites More sharing options...
pansontw Posted April 2, 2008 Share Posted April 2, 2008 SEARCH IN http://www.rs25.com/ FOR CAMS FOR NA There is a guy very happy w/ his new cam. Quote from him" This thing now pulls like a train".......... Link to comment Share on other sites More sharing options...
scoobydoobie Posted April 3, 2008 Share Posted April 3, 2008 Look at delta cams, they reground your stock cams for a fraction of the cost of TWE or COBBS. There is a core exchange program going on rs25.com. Link to comment Share on other sites More sharing options...
Brad023 Posted April 3, 2008 Author Share Posted April 3, 2008 I was told to go with tech works any idea on what kind of numbers i should get by adding cams. car has headers, full exhaust 2.5 inch, intake, piggyback Link to comment Share on other sites More sharing options...
scoobydoobie Posted April 3, 2008 Share Posted April 3, 2008 Delta will do the same thing just save you $$$, probably 20-30 hp Link to comment Share on other sites More sharing options...
whitetiger Posted April 3, 2008 Share Posted April 3, 2008 I was told to go with tech works any idea on what kind of numbers i should get by adding cams. car has headers, full exhaust 2.5 inch, intake, piggyback with a good tune, you could see 200 peak crank hp. So maybe 150-160 whp. your actual 0-60 acceleration may not improve that much since you have the 4eat trans. So along with our tune, maybe you can find someone to remap the shift paterns to get my better accel. Link to comment Share on other sites More sharing options...
Brad023 Posted April 4, 2008 Author Share Posted April 4, 2008 my friend has an S4 and he got a chip to change the triptronic shift time from 1 sec to .02 sec. does subaru have any thing like that out. i don't think so but just asking. Link to comment Share on other sites More sharing options...

I'd try to get in contact with diferent tuners to see if this is possible for the 4eat. Link to comment Share on other sites More sharing options...
pansontw Posted April 4, 2008 Share Posted April 4, 2008 If You Are Getting A Tech Work Cam, I Will Be Highly Interested In This. For The Delta Cam, Some Guys In Rs25.com Had Some Issues W/ Delta Cams. Link to comment Share on other sites More sharing options...
massdrewski Posted April 5, 2008 Share Posted April 5, 2008 Im thinking it from the other perspective. Towing capability. With the extra power, you wont really get faster, but your towing capability should be beter. Lower end Grunt force. should be interesting to see Link to comment Share on other sites More sharing options...
tougefox Posted April 5, 2008 Share Posted April 5, 2008 If you search the forums theres a company....i believe IPT that will take your valve body and work to give faster firmer shifts. Ive seen a few 5eat people do it and they LOVE the results. Say its night and day. You and i have the same setup and probably will have the same mods. The only difference is mine will all be TWE, and im upping the compression. I dont post on here too much been working a lot but my build is pretty secretive and i dont wish to release the specs of anything. Best of luck to ya!

WhatV8 Posted April 6, 2008 Share Posted April 6, 2008 How can the AVLS know what the profile is on aftermarket cams? Wouldn't it be adjusting knowing the OEM cams? I would think that is why you would need a piggyback ECU, so you can adjust the activation of the AVLS to get the most out of the aftermarket cams. If the new cams are geared toward a higher rpm band, then the AVLS should be shifted appropriately. Of course you could likely degree the cams at install to select where in the power range falls (i.e.- advance or retard the cam timing). Link to comment Share on other sites More sharing options...

That would make the 2.5i a MUCH better car. The 4EAT is the weakest point of the car, IMO. Link to comment Share on other sites More sharing options...
