Default Grinder's 07 STI

Well i bought my STI off a good friend last summer ('10) and have been planning out my eventual build. For now I've gotten the suspension and exterior most of the way to where I want it, but the engine is still stock (for now!)

I plan on keeping this car a DD for the foreseeable future, so reliability and driveability are paramount. I also dont care about huge HP numbers, especially if it requires a slow spooling turbo that doesnt develop any power until 5k RPM anyways. I'm used to driving a supercharged car, so I like my power immediately!

After reading some more posts and journals, i'm reminded that its not just hp that matters (except bragging rights) but hp/weight ratio. Plus, lowering weight helps with handling.

I'll need to start doing some calculations and see what kind of returns i get from upping the HP vs lowering the weight.

I'm trying to find the biggest bang/buck weight mods now. Looks like the low-hanging fruit here is:
1) Remove spare/tools (for around-town trips only i suppose)
2) Front lightweight bumper insert (oswald or JDM?)
3) Rear wing removal
4) Battery relocation (i'm hesitant)
5) Cat-back exhaust

But most of that weight is off the back, oh well. I'll start making my list of prices and savings soon. For now its just brainstorming.

Okay so it's been a while but i've ordered the GR 3-in-1 gauge. We'll see how it looks in the GD interior, and how i can think to mount it. I've also been avidly reading and scheming about my plans. I think my next couple of things will be freebies or cheap mods:

Truely free:
1) Remove airbox silencer
2) Remove subframe
3) Remove bar under rear seats

Cheap:
1) Add foglight bezel/intake
2) New panel filter
3) Lightspeed chassis bridge
4) Air pump removal (i might need an AP to clear CELs so maybe not) (also, requires block-off plates).
5) Lightweight bumper beams
6) Wingless trunk

I'm still trying to do things as economically as possible at this point, but I've got some good things in the works for the next couple of weeks.

First, I already removed the bar under the rear seats. I dont carry passengers that often, so I'm not too concerned about comprimised comfort.

I also now have a set of Volk TE37s in 18x8.5 +40 that I'm quite excited about. They wont go on until the spring, but I cant wait to see what they look like. For my winter setup, i've now turned the OEM rims into my winter rims and just mounted a set of Dunlop winter tires. We'll see how they do on some upcoming trips to PA.

The next few weight-savings mods are:
1) Removing the U-brace beneath the car sometime in the near future (perhaps when it gets warmer!).
2) Swap front bumper beam with JDM bumper beam
3) Install a lightweight battery (i'll probably wait for the spring to make sure i dont have any cold-start issues).
4) Swap for a wingless trunk.

As for suspension:
1)I'm planning on getting a Litespeed Chassis Bridge in the next few months to help stiffen up the chassis. While the debate is out on how much it helps vs placebo effect, it's certainly not going to hurt.
2) I'll probably get some sway bars, as those are a fairly cost-effective way to bump up performance.
3) Down the road is probably the AST4100 coilovers, but some RCE T2s isnt out of the question. I'll have to do some research and figure out what the extra few hundred gets me.

For power
1) This isnt REALLY power, but its more power than anything else. I'm going to make the passenger fog bezel into an intake (plummed into the intake silencer's attachement point)
2) Cobb APv2 is really the way to go. It'll also allow me to remove the air pump from the engine bay which is an added bonus. It seems like the AP is necessary for ANY other power mod.
3) This will probably be a combo of in-tank fuel pump and injectors (i have to figure out if 850cc is big enough for my end goal) and get and E85 tune.

I finally got around to installing my CF trunk. At first, i tried to do the swap by myself, but as soon as I got the torsion bars loose i realized just how heavy that trunk is--and decided i needed a 2nd set of hands. Incidentally, i found removing the torsion bars to be super easy, as you can just tap them out with a hammer.

I had my girlfriend help me that evening, but things didnt go very smoothly. I couldnt get the trunk to latch, and more importantly, I couldnt get the screws for the support arms in more than about a half turn. I drove around (very gently!) for a few days until the weekend, when I went to a friend's house to fix everything. It turns out the guy who sold me the trunk had tried to jam the wrong thread screws into the trunk, crossthreading it. We managed to fix the holes with a tap, and everything works well now.

Getting everything aligned was another problem.
Useful thread #1
Useful thread #2

Even after angling both latches as much as i felt comfortable with, the trunk really didnt want to close properly. I ended up solving the problem by filing out the holes in the trunk support arms, allowing the whole trunk to move slightly further back in the car. I'd still like to do a little bit more filing, but it was 25 degrees outside, and it was starting to get dark.

I didnt end up getting to the JDM front bumper beam yet, but I'm hoping to do that soon. Hopefully I'll take off that rear subframe too for maximum wight savings!

Spring's coming!

I've got tons of goodies ready to go on the car including:
JDM Bumper Beam
Zzyzx EM Sport Coilovers (hopefully shipping today)
TE37s
Whiteline 24mm adjustable rear sway bar

Before i do the installs I'd like to have sourced some endlinks and a front sway bar too. My friend helps me with all my installs, and should be able to help me corner balance, but alignment might be more of a problem. I've never done an alignement myself, but he says he's only got equipment for Honda stuff. Maybe I'll take it to Ptuning, I've heard good things about them.

I'm also moving in the next two weeks, so this could get chaotic. I'm hoping to get tons of pics of before, the install, and after since I dont have ANY pictures so far.

Adjusting my the rear Konis was getting to be a pain in the butt. I fashioned an extension for each side..what i consider to be a work in progress. Its pretty cheap, about $10 a side.

Parts:
1) 6mm flex socket, 1/4" drive (can substitute a 6mm socket AND a u-joint)
2) 1/4" drive extension 7-9" (6 is just barely too short, 9 is max length)
3) 1/4 thumb ratchet







On the floor is the 6" extension (too short). In the car is the 9" which is almost touching the rear windshield. So my next plan is to source an 8" extension and glue the ratchet so it doesn't ratchet. From there I'll put some lines on the ratchet so I can tell how much the wheel's been turned.
