Re: Willub's 04 STi: ee eighty five

YOU HAVEN"T ALIGNED THE CAR!?!?!?!? wtf dude!! GO DO THAT NOW!!

I had a small amount of toe out on my car and I was last in class, fix the toe problem, and I was 1st!! Alignment is critical.

Are you going to stop with the 1.5xtr? or do you plan on going bigger later?

You need a set of side feed TGVs to tinker with? Mine are for sale. ;)

Lol I knew you'd comment on it not being aligned. My friend has told me many times that he was going to take it one day and do it, but he no longer seems interested :tdown: The old tires were trashed so it wasn't a huge concern, but now it is.

I think the 1.5xtr may be it. The only other turbo option I'd consider is a low mount 30r type dealio, like killer B's. That's out of the question for now though.

:lol: No thanks on the tgv's, I'll be tinkering with my own :)

Re: Willub's 04 STi: Devens Match Tour

I recently had an epiphany on what the noise is coming from the rear of my car. The noise became very noticable right after I put the coilovers in. I didn't think much of it at the time, mainly because the back seat was out and I figured the extra noise was due to that. However once I put the seat back in it was still louder than before the coilover install. I still figured it was a wheel bearing. The new bearing helped but the noise was still there. I think it has been tire noise this whole time, due to misalignment. I have yet to get this car aligned since I have owned it. I really hope that's all it is.

Another topic, e85. Why? Because I'm a power hungry bastard! :lol: I would only be running e85 for autocross, since it's a 30 minute drive to the closest e85 stop. This is the parts list I've been thinking of.

Injector Dynamics top feed conversion kit
DIY TGV deletes
Some sort of hard inlet while I'm in there
Better in-tank fuel pump
New HD clutch

The plan is to drain the gas and swap tunes the night before a race, and throw some e85 in. I think I remember seeing a drain plug for the gas tank the last time I was under there. I'll check again.

This will obviously require two new tunes. I'm going to attempt tuning the car myself after I put the new injectors and fuel pump in. If the motor goes then oh well, it's done it's job long enough and I have been planning on it going anytime now. I'll start ordering the new parts soon and probably wait til the end of the autocross season to begin installing them so I have time to tune it. The ID coversion comes with 1000cc injectors and new rails. Will 1000's be sufficient for e85 and my 1.5xtr? I've read that my current injectors (dw 850's) almost flow as much as the ID 1000's.

As always any recommendations or advice is welcome! Brake stuff comes tomorrow!
Sounds like a lot of fun - but if you're only doing this for autocross, do you think there are other areas where that $$ could be spent, and still go towards better/improved times? I don't know what your long term plans are, but if it was me I'd maybe invest in race tires/wheels, or some other handling type parts. (brakes, bushings, etc) If you solely want more power just cause, then of course there is nothing wrong with that. :D

I strongly looked into E85 for autocross only as well. After consulting with Bren and doing the math, I would require DW1000cc injectors ($549), a new Walbro 400lph pump (E85 safe pump, $160), and Perrin V2 fuel rails ($400). According to him, these items would be required in order for my car to run well, fully tuned, on E85. And that's with a STOCK turbo. :lol: According to him - the ID1000's flow about the same as DW850's. The manufacturer measures differently.

Based on my research, for the stock turbo - thats about a 15whp and 25wtq increase for $1109.

PS: Get an alignment :lol:

Nailed it. :lol: Race tires/wheels should definitely be the next thing, but I love power :) Who knows, I may do wheels/tires as well by then :naughty:

Yeah I may as well go bigger on injectors to be safe. I heard the same thing about the ID 1000's. I want to at least get the car e85 ready at the end of the season. The problem with using the stock turbo is that you can pretty much max it out on 93. It starts dramatically losing compressor efficiency after 20ish psi I believe, so you're just super-heating the air going in to the engine, much more than the intercooler can handle. With the 1.5xtr it can be pushed to 25ish psi on e85, which would murder my engine once and for all :lol: TopSpeed did this and made 442whp/470wtq :D and that wasn't even the limit, they maxed the fuel pump. Their dyno reads very similar to Bren's. Fun? Yes.

Re: Willub's 04 STi: ee eighty five

the 1.5xtr sounds pretty awesome!! what sort of boost threshold are you seeing?

This is my old tune on EFI's low reading dyno with only what's listed down below for mods, minus fuel rails. No boost plot on the new tune :( As you can see it begins boosting much earlier than 2500. I would say it starts boosting around 2100 in fourth, but obviously takes a while to build up to full boost. When I drove mickle's car I was expecting it to feel much different than mine as far as lag goes, but it didn't. His peak torque hits at 3100 or something stupid low, but that's in fourth gear on a dyno. I think it feels very similar between the two turbos because we are only using first and second on course, with a little third sometimes. There isn't as much load on the engine in the lower gears so the turbo can't spool up quick enough for much of a difference to be felt. A good example of this is when you rev in neutral. No load = no boost. At least, that's just my theory on what's going on

Re: Willub's 04 STi: ee eighty five

I will be installing these this afternoon :)



Parts are on the way as well. Here's what I ordered

ACT Streetlite flywheel
Exedy Heavy Duty stage 1 clutch kit
Beatrush motor mounts

I figured I may as well get a new flywheel since resurfacing this one is not cost efficient around here. I need a new fuel pump as well. My walbro is squealing like a bastard upon start-up.

I should be able to find time to get the new clutch and mounts in before the next autocross. There is one tomorrow but I'm skipping it to save my tires. It's not at the normal location and about twice as far away for me and no one registered in SM the last time I checked. With the car not being aligned yet it isn't worth it to me.

Re: Willub's 04 STi: ee eighty five

Got the brakes done and the extended studs installed. Believe it or not I didn't break any caliper bolts! One front one was stuck in there but after heating it up and cooling it down a few times it came out. One rear bleeder did snap though. It almost looks welded in due to the corrosion around it.

Yeah, these rotors were toast.


New stuff on



Broken bleeder. Luckily it didn't start to loosen up as it broke.




Errr. Yeah, all of that air came out of the caliper :lol: I opened it to let it gravity bleed and nothing was happening, for a while. So I put the pedal to the floor and propped a piece of wood against the seat to hold it down while I closed the bleeder. Only a tiny bit of fluid came out, then the bubbles started coming. Safe to say these brakes hadn't been bled in a while :lol:




One front bleeder was clogged up so I pulled it out and blasted it with compressed air. Fixed!

It's nice having brakes that work! Ferodo says to do 25-30 emergency type stops to bed them in. It was late so I did maybe ten total. I didn't feel like pissing my neighbors off too much :) I accidentally got the ABS to engage once, which never would have happened with the old stuff.

Damn buddy, you aren't kidding, those rotors... they look pretty thin. Borderline frisbee's...
Glad you got it all done. Good job!

Re: Willub's 04 STi: ee eighty five

Gravity bleed for the win! It takes a a LONG time though - I let it sit sometimes for 15 minutes PER nipple.
Yep, did exactly that. I cut the time down by doing the rears together and the fronts together. Both sides kept flowing so there wasn't any wierd vacuum effect on one side or the other :tup:

Yeah, I believe they were the originals. Tons of gouging on them too

Re: Willub's 04 STi: ee eighty five

Holy sheet! I didn't know there was another autocross coming up this weekend. The clutch and stuff is scheduled to arrive next Monday so I guess I'll have to take it easy on the start still. My friend will be aligning the car Saturday! This will be my first event with the new wheels/tires, brakes and a properly aligned car. It's gonna be like driving a different car... again :lol: I'm thinking about swapping out the rear 24mm whiteline bar for my stock one, since I was actually getting a smidge of lift at the last event and the rear is very twitchy. I think I will wait though and get a feel for what it's like with the new tires and a proper alignment.

Re: Willub's 04 STi: ee eighty five

I've gone back and forth with the rear bar thing (22/24 white line and stock) and ever since I did the coilovers the bigger bar has always made the car feel worse. Regardless, its never bad to play around with different settings and see what you like the best. What are you thinking for alignment specs?

I'm betting it will be the same with my car, but you do have 100lb/in stiffer springs in the rear, so maybe this bar will be good for my setup.

-3* camber up front
-2* camber out back
0 toe all around

I took a look at my centric bolts that adjust rear toe last night and they look awful. I sprayed them with PB and left them. Hopefully I can loosen them up tomorrow night without an issue.

Re: Willub's 04 STi: ee eighty five

Fawk! I didn't realize this next event was on a Saturday. I can usually get the day off but it was too last minute this time. Oh well, that would put the alignment on hold even longer anyway. Of course some people decided to come out and play in SM this time.

Oops....

Yeah, the same here. ASP has that guy M. Allen that floats in and out and he is signed up. Too bad I won't be there to show him how its done and I'm assuming Josh isn't going either, with the diff not done. He better enjoy his free trophy while he can! :lol:

Re: Willub's 04 STi: ee eighty five

Well I had to hold off on the alignment since I couldn't get the nuts on the rear toe adjustment bolts loose. I tried everything except a breaker bar, since I had to drive the car later that night and was confident that I would break a bolt. I'll give it a go Thursday night with the bars and pipes and stuff. I've read threads from 2004 where people had issues getting these things out :lol:

I got my clutch, flywheel and motor mounts yesterday. I may start doing that Thursday as well. Hopefully with the lighter flywheel my revs will drop quicker between shifts, resulting in easier shifting. Between that and the new beatrush motors mounts, I'm hoping my random "why no go into third gear" issues will go away. As for new gear oil I'm thinking of trying some "cocktail" as they call it. Some people swear it helps a bunch with these transmissions if you're having grinding issues, so I'll give it a shot. I just have to see which gear oils people mix.

Re: Willub's 04 STi: ee eighty five

+25mm offset up front with a 275 will require you to get some "bumper pusher outers" (just a heads up ;)).

I'll be plopping my current z2's on the new wheels (at some point) :) I'm sure I'll still need to do a lot of work to get the 275's to work well with my current 17x9.5's, especially if I keep the same ride height. If I don't end up with Josh's old 275/35/17's I will be getting 275/40/17's. A6's of course :)
