Wow. That was fast! Are they putting it in too? What's wrong with yours?
My third gear is really difficult to engage and now 4th as well. Im in Miami so I will be installing but they will assemble. They advised me to try using some cocktail first in order to weed out some things. Nonetheless Im going to need it so screw it, PAR here I come.

New gears wouldn't be a bad thing but I'd be willing to be your stock ones are fine. Sounds like you just need new synchros. Only a couple hundred bucks.

Could be but eventually i will need it. In the next few months I will be close to 500 wheel tq so as you already know its a given.

Sounds like my shift fork issue. My mechanics saw a 2010 WRX's shift fork wearing like mine was before it broke.

I heart xluben's gears. So robust.

Well might as well just do it once then I suppose. What turbo to hit 500WTQ? Seems like the Subaru guys don't run enough boost on the bigger turnos to make that much.

Your 3-4 fork broke? Where exactly? What kind of wear did it show? My forks all looked fine. Odd issue that they'd break unless you're really slamming the gears.

Dom 2.5 , i used 500 as a reference point not actual #, but I do think its possible to get close.

E85, right? Crank the boost up to 28psi and it should be close.

Yea 85 headers etc, i think I can get pretty close. Thanks for the support.

Peak torque should at least match mine. Probably will spool a little later but it will make better top end. You'll need to crank up the boost close-ish to 30psi and be on a high-ish dyno to make 500WTQ though. Run 24psi like a lot of people around here and you'll probably see less torque than me with similar or slightly better power.

What's your motor and fuel setup? I think those are holding me back from going any further.

At the moment stock block but im in talks with a local builder, as far as fuel walbro255, dw1000's. however im considering an aeromotive 340 with a BAP. Then see what happens.

Yeah, I think that engine will be a time bomb and the fueling will definitely limit your power to something similar to mine. If you run the Aero 340 on E85 then let me know how it goes. It's the biggest stock location pump but I've read some good and some bad things about it on E85. It would definitely be the easiest way for me to squeeze some more fuel out of my system (especially when paired with an FPR and/or boost-a-pump).

Doesn't the DW65C outperform the 255?

Supposedly 265 vs 255 L/hr, but I am guessing the difference is negligible if anything. Mostly just trying to justify 2x the price for drop in fitment.

Lots of good stuff in this thread. Seeing as I'm trying to prepare a list to start gathering parts I hope y'all will talk about the fueling setup a bit more

Well right now it's just a Walbro 255 and Five0 1200cc injectors. I'm pretty much maxing it out with my current power (on E85). I'm not sure if/when I'll go for more and what I will do at that point.

Here's a video of the mounts + straight cut gears. It should be HD soon. I have a second video uploading now.

About startup noise:
I have done basically every bushing possible except motor mounts on my '12 STI. This includes TIC's crossmember bushings which I see almost nobody doing and stock were jokingly pliable. http://turninconcepts.com/product_in...roducts_id=310

Anyway. I mostly used Group N stuff to avoid tranny whine and general noise. I consider myself to have a generally conservative view on noise. The front/rear shifter bushing added the most noise of all mounts/bushings (including tranny mount) for me but it was easily acceptable. Until that solid pitch stop. Cranking the starter sounds like a... digital jackhammer or something. Personally startup happens so rarely that it's fine with me and it's was very worth it since it tightened up the drivetrain the MOST out of every bushing/mount I have done. I agree that's the most likely cause of start p noise.. The motor mounts probably only add to the problem.

Personally, if my imaginative wife complained of noise I would know it was the awesome pitch stop and then I would cough at every start-up to cover it up.

Thanks for the info. Those crossmember bushings are really, really soft. They're like complete mush. I had actually considered just getting some machined out of aluminum, but I figured I might as well try it with the new tranny and motor mounts for a while first. TIC's hard plastic ones might be a good option.

I really didn't find the shifter bushings to add much of anything for NVH. Probably 1% of what I added with the recent mounts. I had done a DIY Group N tranny mount prior to this (3M window weld in the stock mount), and it didn't really change anything as far as I could tell. It's good to know the pitch stop is what is causing the crazy start up noise.

The start up noise is odd, but not really that big of a deal. The extra whine in all the gears while driving is quite loud and obtrusive though. But it does seem to be smoothing out (break in of bushings), either that or I'm just getting used to it. I may have to try swapping back to the stock pitch stop someday. It only takes 5 min and then I would know exactly how much is due to that vs. the other mounts.

I personally loooove the sound of straight cut gears!!! I don't know if I could handle it as a daily but it sounds like it's pretty tolerable from the video. Now if you would make some flip switches for your fuel and starting system we can really get this project going.

It's not that bad, but the video definitely makes it seem quieter. Also, it's really quite loud when engine braking. The flip switches might be kind of cool, but seems totally pointless. I'm not interested in making the car harder to operate for no reason other than looking cool.

Looks good! I'm surprised you would do something like that. I really like the colors on the first photo. Did you use multiple polarizations on that?

Lol! Just saw your post in the DSLR thread commenting on the colors and the multiple polarization!
