im thinking of going with the gsc s2 cams, anyone have some good experience with these? my tuner recommended them, the goal overall on this car is to be between 500-55whp on pump gas. Im hoping cams, springs, and equal length header will get me there.

I think the GSC S2 cams are a good choice as well as the Kelford R199C 04-07 or the 220-C cams DAVCS for your 09. They are both 272 duration. I could have easily gone with the R199C and I am wondering if I should have but I am making good power with the R199B/ 264 duration Kelfords!

What headers are you going to use? I would highly recommended the Killer B Holy Header! They are pretty amazing in their performance and the quality of material and fabrication is very high and robust!

I'm sure you know this but you'll need a bigger fuel pump and rewired as well and probably a FPR. You are going to do a 110 oct RF tune, why not E85?

i had a 400lph fp, aeromotive fpr, -6 lines, and 1300cc injectors put in when i got the car tuned. i haven't really started looking at equals yet but i appreciate the recommendation

No worries! If you get the car in the air or are underneath it you should be able to read the case number off the castings. It does not really matter at this point or at all. You either have stock sleeves or a sleeved block. if they are stock sleeves then I would stay with 99.5 bore.

the block is not sleeved, and to answer your question for e85 its not available enough around me to want to run it again. Only one station has it and it was a pain when my termi was on it.

If it were me I would look into running meth and cranking the tune to where it was at 505hp.

500+hp on pump gas is not a good idea IMO.

I would feel more comfortable on pump gas than running meth, Have heard too many horror stories about it.

I'm with SWOOP, I'd take it a bit easy on the pump gas and the eagle rods! Cams and head work will extend the power band out without it falling off. I have a solid 4k power band 4-8k with my Dom 3.5xtr with both pump and E85.

ok so a little update for you guys, i hhad the car re-tuned on e85 and it made 490whp and 440wtq. got a new station by my house so i figured why not. Now heres where things went bad, i started having a leaning out issue. i about pooped my pants when i went wot and my air/fuels jumped to 14.5! couldnt figure anything out, kept looking over the car and didnt see anything wrong. so i ended up taking it to my tuner and he found a vacuum line that had come off. good news is i fixed that issue, bad news is now my motor had low compression in two cylinders. Now my motor is out and apart. Looks like i need pistons and to bore the block out. At this point in the rebuild im just at the screw it phase and decided to go all out haha. I have decided to sleeve the block, build the heads, and add a equal length header. For heads im not set in stone with my plans but me and my tuner have agreed to do gscs2 cams, springs, retainers, and valves. The header im going with is the ams race header. i have read some horror stories on this header but what made me go with it is another sti at the shop. this other sti had a perrin equal length and it was being restricted because the heads flowed so much. Just from going to the amr race header he picked up just over 50whp! But none the less the only thing that will be holding me back now is my fuel system.

I would go with the Killer B Holy Header! Your fueling with the Walbo 400 and DW1300 injectors should be good for 600 WHP.

Ever think of trying the brian crower stage 2's? I just got those on my build with a gtx30r and in the words of my tuner "this thing just wants to keep pulling" we drew the line at 8k seeing I want this thing to last.

The Crower stage 2's are not 272's they're more like 264's like my Kelford R199B's or the GSC stg1 cams. I would go with the GSC stage 2 or the Kelford R199C's; 272's.

With that Wally 400 pump and the 1300's you should be able to flow enough fuel for 600 WHP. Did you hardwire the pump with larger gauge wire? You need to do that and run the FPR so you can adjust the flow of the injectors some if needed,

I made 560 WHP on E85 with my Dom 3.5xtr, hardwired wally 465, Aeromotive 1000 FPR at 55 psi base and my ID 1000 injectors with Perrin rails! We maxed the injectors above 100% at 27 psi to make that power! Junior then backed it off to 25 psi to be safe until I can get the ID 1300's when they start shipping them.

That's good! There's nothing really wrong with the Tomei's other than the fact that they're an old design, made with 304 ss opposed to 321 ss, have slip joints because of the 304 and don't positively affect the VE of our Subaru motors like the Killer B Holy Header does! The Killer B Holy Header is absolutely the best header on the market for turbo Subaru's!

Go with the GSC stg 2/ 272's!

You should just buy the 465 and do the rewire/ hard wire if you haven't yet. You have an adjustable FPR right? Then sell the 400, it'll go quick!

They're not cheap but 900 vs 1275, that's a small $ amount of your build but they will have a huge affect on your VE and power! Do yourself a favor and talk with Chris at Killer B before making a final decision, you won't be disappointed!

Here's a quote from Junior on this guys 2011 sti w/ Killer B header thread;

The rest of those brands are pretty much the same basic design that has been around for years

Water METH with a safety switch is pretty reliable. If your run out of meth OR the system fails the car reverts to wastegate pressure. You tune the wastegate pressure to be safe on 93.

If your going SpeedDensity this is very easy to achieve.

You have Si drive right, so you can set sport with the 93 pump gas map and sport# with the E85 map. Then run a solid, safe low to mid 20's psi pump gas map and save the high boost, fun map for the E85 in sport#!

car is already on a speed density set-up. A new e-85 station opened up about 5 miles from my house so the car is going to be on e85 99% of the time.

My tuner usually just gives me 3 different boost levels for each gas.

OK, my mistake on that. Scratch that idea!

Switching fuels would require a full reflash and I'm sure that Si drive uses a fast real time type flash to change the setting. You'll still have both pump gas and E85 right?
