[quote=midwest impreza;40656030]^oh thats because the driver side fan is the main fan and the passenger side is the ac fan. main fan no. ac fan yes.[/quote]

Actually he said these cars tend to run hot and both fans were needed to help prevent overheating.
Vlad 09-27-2013 07:32 AM

The fans are controlled by the ECU via a table in the ROM.
The second fan is not only coming on due to the AC.

Is the blower motor needed to move heat?

Got new sparco monzas, but they seem to be as heavy as stock :huh:

eagle rods 83g/rod
haven't chose pistons yet
lwfw 17lbs
driveshaft 14lbs
pnp heads and intake mani, lol its something right
tgv delete unknown weight
abs delete unknown weight
brake booster delete unknown weight
single brake line to the rear unknown weight
single stage paint, used less than a gallon to cover the car ~10lbs
fiberglass ic splitter unknown weight
I cut a bit off the front bumper beam unknown weight

I've don't quite a bit of reduction, I bet I'm around 2800lbs now

This X2


Out of curiosity, has anyone replaced their OEM metal intake manifold with the newer plastic one? And if there's an intercooler (top mount) that performs better than stock+is lighter?
Str8Gone 09-28-2013 11:31 AM

Cruise was easy to remove on my 04, just pop the cable off the throttle body and unscrew the control box and take off the harness that connects it. Most aftermarket intercoolers are heavier than the stock aluminum unit.
LIQUIDSK8S 09-28-2013 12:30 PM

Just swapped my 02 WRX (leather) for S204 seats. The following weights include hardware.

WRX:
Drivers = 51lbs
Passenger = 45lbs

S204:
Both = 42lbs

Removed my sunroof and put a carbon roof on which dropped 45lbs. I'll try and post up the full list of weight loss but I'm around 2850lbs now with full interior, sound deadening and a STi drivetrain.

lol ya, the msds said 8.3lb/gallon and voc weight was 4.5lb/gal, so 3.8lb/gal of solids. Used about 1 gal less than oem through all the primer, sealer, and color/clear, and applied with hplv gun not static like oem so more lost to overspray. So its probably more like <4lb over the entire car, lol its just as ridiculous as some of the other stuff in this thread.

I find it hard to believe ur at 2850
I've done a lot to mine and it's just over 3000

I don't see how I could even lose another 150lbs

I'm interested to know if anyone has used the plastic intake mani as well. Probably not the place to ask, but I wonder if it yeilds any gains other than weight since it should disipate heat much faster

Finally installed the Oswald beams and they were a great mod on top of my recent list of weight reduction mods. I'm not sure of the savings, but I've become addicted to losing weight ever since I found this thread.

[U][B]07 WRX[/B][/U]

So far:
. Seibon CF trunk (wingless)
. Seibon CF Hood (I trimmed the internal fiberglass of the hood hoping it wouldn't be heavier than the OEM one)
. Oswald F+R beams
. Odyssey 680 MJT in the trunk
. Grimmspeed Crank pulley
. APR side mirrors
. Forged pitch stop mount (.5 lb lighter, nothing crazy)
. V2 koyo radiator
. Custom TBE with an apexi muffler
. Coilovers (stance gr) not sure if they are lighter than the OEM setup.
. light wheels (ssr comp c's)
. Air condition, windshield wiper system, cruise control, spare wheel, front "U" subframe...DELETE

Want:
. 08+ plastic intake manifold, if compatible
. possibly a lighter tmic, aluminum?
. MAW Composite TGV's
. carbon or aluminum driveshaft
. lightweight flywheel
. more weight off the front!!!!

RavensFan7 10-01-2013 08:52 PM

Stock L model is 2730~

So far I've:
-deleted the a/c (34 lbs I think?)
-deleted the washer fluid tank (5 lbs full?)
-removed the snorkus and other weird intake bits to make it smaller, lighter and less tubing (5 lbs?)
-removed some trunk stuff: carpet, tire cover, spare donut (20 lbs?)
-lighter wheels than the steelies (2 lbs less per corner, so 8 lbs)
-lighter battery, but not a super light one (10 lbs less)

So I'd say a good 80-90 lbs have been removed so far. Still need to:
-delete the power steering
-super light weight battery
-some sound deadening removal
-wingless trunk
...and I have a plan for the trunk to save some more weight there

I daily drive this thing so if I can get into the mid 2500's I'd be happy. I'm gonna try to get it weighed tomorrow.
bue car 10-01-2013 09:10 PM

Have you driven these cars with no PS? Hulk smash!
RavensFan7 10-01-2013 09:25 PM

Lol. It shouldn't be [i]that[/i] bad without.

I've moved my car many, many times just pushing it or coasting at walking speeds.....all those times turning the steering wheel wasn't all that hard. When you get above 5-10 mph it's not really needed.

Also, when i drain the rack and grease up the pinion stuff it should make it easier to turn the wheel without all the fluid working against me. Should get easier as I remove more and more weight too.

Just sitting still and trying to turn lock to lock.....yea.....you're gonna get an arm workout lol.

That one dude on here/rs25 has his gc down to 2000 lbs (2019 maybe?). Makes me just want to go rip everything out right now.
LIQUIDSK8S 10-10-2013 04:38 PM

Just going over my unsprung and rotational weight. I did a spreadsheet comparing my current setup (JDM STi drivetrain) to both a 02 WRX (my chassis) and a 05 USDM STi. The results between the 02 WRX and 05 STi were shocking.The 05 STi has about 66lbs+ rotational weight over the 02 WRX. The unsprung weight was around 31lbs more for the STi.

Here's a list for my unsprung weight comparing stock STi parts to new ones. Weight loss of 75.5lbs unsprung weight vs a 05 STi.

Stock wheels 76lbs Prodrive GC-010E 72lbs
Stock Front Rotors 46lbs Brembo Front Rotors 38lbs
Stock Rear Rotors 36lbs Girodisc Rear Rotors 22lbs
Wheel Lugs 2lbs RAYS Lugs 1lb
Rear Struts 35lbs Rear RCE Struts 28lbs
Front Struts 38lbs Front RCE Struts 30lbs
Dust Shields f/r 3.5lbs
Stock Tires 108lbs Pilot Cup tires 88lbs
Front Calipers 26lbs Front Brembo BBK 16lbs


For rotational weight, I dropped 68.5lbs vs a 05 STi

Driveshaft 24.5lbs ACTP CF shaft 14.5lbs
Stock Pulley 5.75lbs COBB Pulley 1.25lbs
Stock Wheels 76lbs Prodrive GC-010E 72lbs
Stock Front Rotors 46lbs Brembo Front Rotors 38lbs

blown subbie 10-12-2013 10:17 PM

ive been reading this thread for the past couple days. ive gained alot of knowledge. although i haven't read every page. i havent read about people removing the abs unit and removing all those extra lines, bad idea? i have my o4 wrx in the garage with a dash and steering wheel left. plan on removing all the tar and whatnot and what others have done here.i have all winter to do things. although i still have a couple questions that might not be related. but does anybody have lexan windows? if so how do you go about getting them and cage options. i plan on just having just the 2 front seats.
blubug_768 10-13-2013 03:06 AM

I removed abs and the booster and re routed all the lines in a lot more simple way, abs is for squares :lol:. I don't have lexan windows, but have seen kits for like $1200. you could probably just buy some lexan and figure a way out to rivet it in for way cheaper though, since your caging it you're probably racing it so check the rules for minimum thickness before you buy.

did you get a different master cylinder? or just t each one for the front and rears?

matched with the prop valve for wrx/sti RA versions (all discs, no ABS) is 27673FA001 which is not available in the USA part number system. It's a JDM number.

Possibly this?

if you don't care, maybe try the auto store equivalent for the 1994 svx? I might need another for a second build, might have to do that myself, or rock auto. It's the valve that is the issue as there is no American Subaru equivalent

That's old news.. I've gone as far as removing the welded nut that holds the tire in place

Big hole in there now
RavensFan7 10-14-2013 02:50 PM

See my problem is that I plan on getting a full size spare soon, so I need to remove as much weight as I can from the trunk/rear to offset the weight of the spare (35ish lbs).

Not much back there to remove though. :sadbanana:

I have a few more things to remove which should net me at least 30 lbs less than stock. That means a full size spare will only add 5 lbs back there, which I'm okay with.

Need to find my spare (donut) tire and weight it, but it has to be like 20 lbs or so right?

The ECU is on the trans tunnel, under the radio I believe. All GC ones are.

The sensors are in the front by the wheels / crash beam. Follow your wiring harness. they are the front side impact sensors.

Got it weighed. Without me it's 2660. Not as low as I hoped but its a start.

Gonna try to remove some sound deadening from the trunk today..we'll see how that goes.

Edit: and the spare donut weights 26 lbs! The full size spare I'm getting weighs 36 lbs, so I should be able to make the trunk/rear light enough that the full size spare is no heavier than the donut was.

JDwhiteWRX 10-21-2013 05:47 PM

So what are these cars like to drive without a booster or ABS? I pull my ABS fuse out for rallyx and the rear always locks up first, would not try it on tarmac.
bue car 10-21-2013 05:57 PM

1. Tarmac and dirt are complete opposites.

2. You still have the ABS unit in the car, etc. With a real delete, you have new lines and such on the car.

I never locked the rear with no ABS, my car came with no ABS from the factory as well, so it's done right.
JDwhiteWRX 10-21-2013 08:14 PM

My question is more for those who had it and then removed it, modern ABS is meant to be pretty good so is the weight reduction gained by removing it along with the booster a step forward or a step backward?

I use my car for racing on dirt and tarmac.

Take off 5lbs by removing the insanely huge piece of steel in your glove compartment.

Now lose 90lbs :D

To get even more weight out, you will have to look at removing tar from the interior, or maybe getting an aluminum deck lid...

Lol, best post I've read on the net today.
blubug_768 10-24-2013 07:57 PM

abs seemed like it would always kick in randomly and led to piss poor braking, for me it was a no brainer to get rid of it. LFB-ing and als made either a booster delete or a vacuum pump necessary, and if I added a vac pump to my car I wouldn't be in the weight reduction thread lol. But in all seriousness the booster delete made braking feel more linear if that makes sense, like theirs more of a correlation between leg input and braking force.

I've been hulk smashin' all week haha...but like I said on rs25 its WAAAYYY easier with the delete done right.

Got weighed a few times since my last update and here's where I'm currently at:

2590 lbs. with slightly over 1/4 tank (without me)

Makes me happy cause my first goal was to break into the 2500's. :)

Since the last update I've:
-deleted the PS
-deleted all the sound deadening (except drivers side and trans tunnel)
-light crank pulley (grimmspeed)
-deleted the hunk of metal in the glovebox

I think I'm forgetting something but it's getting pretty light. I still need to:
-super light battery (-20~ lbs)
-driver side/trans tunnel sound deadening (-10~ lbs)
-shave metal/cut metal from the alternator brackets (-2~lbs)
-cut some metal from trunk (-2~lbs)

After all that's done I should be able to reach my next goal which is stay in the 2500's with adding a full-sized spare. I know it seems dumb to add weight after all this but I need a real spare.

Haha ok, if I sell it, I'll contact you. Since I've spoken to you a lot on this forum.

But anyways, what do you guys think? Because It's too easy to remove weight off the rear, the front is a major issue and we shouldn't make it worse.

Thanks for the opinions Nasioc
JDwhiteWRX 11-08-2013 06:20 AM

Well after another year of dirt racing I just could not be bothered to vacuum my car so I decided to remove the carpet instead and finally install my 4-point roll cage.

So far I have removed the front and rear carpet, rear parcel shelf, what was left of my stereo (HU + 2 rear door speakers), center console and plastic trims from the lower half of the car, roof liner and upper trims still in place at this stage. All up this weighed in at a hefty 29kg. I still got to remove the A/C but will worry about that later in the year, maybe remove air bags too.

The cage weighs 25kg and I will begin installing that next week as I want it in for the 2 day dirt Autocross I just signed up for on the 23rd/24th.

Over Christmas I will be cleaning up the interior, installing foot rests (rally style) and painting inside the car including the cage.

The cage has been sitting in my garage for about 6 months.

Without the cage my car is around 1235kg with a 1/3 tank of fuel, not bad for a GD.

[B][U]3 Questions[/U][/B]

1. Has anyone swapped the 08+ plastic intake manifold into a 02-07 wrx/sti?

-I'd like to do this while swapping for Composite TGV's to remove more weight from the front, especially since it is elevated weight above the axles.

2. Is there a TMIC that is lighter than any of the OEM one's, I've only had the spearco which is obviously heavy.

3. Would replacing the OEM up-pipe and headers also be worthy for weight off the front end?

- I'm not sure of the weight difference when comparing OEM to aftermarket of those parts

Thanks for any information!
