The EJ255 and EJ257 are nearly identical aside from piston dome shape. The cams are the same, both being single AVCS and the heads are not different enough to flow more. The gear ratio's don't produce more torque either.

If you meant to say that the tuner would feel safer putting more torque through a 6 speed than a 5 speed, then I would agree.

Cams are the same
http://forums.nasioc.com/forums/show....php?t=1762511

The pistons are identical except for the difference of 2 cc of dish volume.
The subsequent compression ratio's are within 0.3:1 of eachother, for an 04-07 STi and the 07 WRX we're referring to here.

http://forums.nasioc.com/forums/show....php?t=1667168

I understand the small nuances between the 255 and 257 but there is not enough there to produce significant power by simply having the same setup.

I'm not some jackwad stating random things....

I have always seen STi's produce more torque given the same setup.

From one link to the next, the contradict themselves.

I don't see how they contradict eachother. Post actual issues that you have with my links. Also, I'd like to see your evidence that STi's produce more torque given the same setup because I guarantee you can't find identical circumstances with same map, same healthy motor, and everything.

Like I said, there are several small variants but there is not enough difference aside from the compression ratio (difference of <0.3:1; due to the piston dish and head differences) to warrant these claims.

The stock wrx (D25) heads actually flow more than the STi's B25 heads.

Well given that the STIs 6 speed has deeper gears (final drive is same) as a WRX you're going to see higher torque on identical set ups. Point blank the 6 speed will have a different gear ratio vs the 5 speed...how can you say it wont have different numbers?
Anyway I am DONE thread jacking Mike's thread...hes a good guy with a solid car....back on topic. I'm over beating a dead horse.

Different gearing in 3rd (5speed) than 4th (sti) and the rear ends have different ratios..no way will number be the same period. It's loading different.

anyway..back on topic

Dyno in the gear that gets you the closest to 1:1. Differences should be minimal due to gearing.

As far as the links, read them closer.

How light did you go? After dropping from the dual mass 28# flywheel to the 17# made an incredible difference. In conjunction with my new to me equal length header, it loves to rev.

Its this one here but I got it locally from No Limit Motorsport

http://www.rallysportdirect.com/Exed...-STI-2004-2011

It definitely revs up real fast, I just hate the noises it makes. If I were to do it again I would definitely stick with stock...If I didnt need to bug my buddy to use his lift I think I would have swapped it already The pros of it just don't out way the negatives IMO.

Thanks Ian, the new shop looks great! I am really happy for you guys that business is going so well. I could honestly hang out all day and just watch cars get tuned. Its cool to see what every ones stuff makes.

I told Adam that after the OCC ASAPCA event I am going to make an appointment for my re-tune. By then we should be approaching September so the weather/temperature should be cooler by then

Damn that sucks. I remember hearing from a friend about anything around that 11-14# mark can screw with the crank position sensor and really make it difficult to drive. Do you do any kind of racing? It took a few months but i got used to mine, sound and drivability.

pickup an sti gauge cluster and wire in the dccd! nice wrx! specs on the wheels?

you should be 110-115 traps. Dont worry about the ET as much. ...Oh and remember, a stock STI runs low 11's at 110 on nasioc

I dont do any racing, I have only been to the track once to run it down the 1/4. From what I understand this will also make launching it harder O well...Live and learn right? I may ask my buddy about using his shop to swap it for a resurfaced stock STI fly wheel before my retune next month. Only time will tell. Actually being able to drive it all this week I am finally getting the hang of it but that doesnt change the horrible noises its makes

Wheels are 18x8.5 +43 If I remember correctly. I love grids although I do wish mine had a tiny bit more crab face.

I actually have an STI cluster in the car I couldnt stand the green so I found one from a member here with nearly the same amount of miles I had. I then converted the rest of the stuff to light up red. I just recently did the fog light switch, now I have to figure something out for the clock and do the master switch. I even got rid of the horrible TR seats and got my some 05 WRXs.

I only have the Manual DCCDpro in the car at the moment but jeff said to try it and if I dont like it I can upgrade to the auto/manual (Now thats customer service!) and then I can get the interface for the cluster.

good stuff man... the 05 wrx seats are awesome. Basically its less expensive sti seats without to blue! ...and they dont show dirt as easy! I say you convert over to the full dccd so you can interface with the cluster... its a small thing, but its one of those things that a suby owner will think "oh ****... thats sweet!" when they see it

True, I would agree.


I like the seats, I have the same fabric and pattern in my daily. I would like to toss some 05 WRX seats like that into the 05 RS since I wouldnt need to do much besides bolt them in. They seats in it are ok. But I like the feel of the WRX/STi seats and they look a lot better too.

Yeah I really do like the seats, the black is so much nicer then the gray. I want to do the the DIY door card fabric change too. I also want to order a new shift boot and parking brake boot from redline to get rid of the fake leather type stuff.

Jeff at DCCDPro is a real stand up guy and said he would credit me the cost of the manual controller to upgrade to the auto/manual one. Soon as I save some extra bucks I am I will probably do the upgrade. For now, I am saving for the retune and really want to get a turbo blanket and a larger tmic before I do it so that stuff will come 1st.

Yup, discussed it with my tuner several times and with the vf39 it isnt necessary. Dont get me wrong, I think a black perrin would look mean as hell peeping through the grill craft insert but its just not necessary. function>form haha

I am thinking of pulling the trigger on a process west tmic and perrin turbo blanket...gotta see if I got the scrap to do it.

6 speed is in, it's awesome except for the light weight fly wheel. I know it's not, but the car feels faster with it, guess its the shorter gearing. Very happy with it overall and now I don't have to fear for the 5 speed which also sold yesterday
