Silicon intake pipe
AVO450L turbo
APS front mount intercooler
Wiseco forged pistons
Equal length extractors
ACL bearings throughout

PPG straight cut dog box
KAAZ front and rear plated diffs
Surge tank
800cc injectors
Custom fuel lines and rails
GFB BOV :gay: :)
Tein coilovers
Adjustable strut tops
Fully adjustable lower control arms
Whiteline front and rear roll bars
Rear diff cooler

Looks like a fun ride.
How do you like the gearbox? Do you use the clutch on up shifts or lift the throttle a bit and slam it into the next gear?

Damm, I'd forgotten how scary those jap "cages" look! Please tell me they actually made them out of decent material.
Does the WRC wing make a difference over the standard one?
Awesome, very cool car. Any in car videos? I notice a video camera in there?
Some very respectable times there, especially at winton.

Gearbox is OK. Only had it in for a couple of Winton practice days and it is very easy to use. On the second day it jammed in second which is a very common issue for PPG WRX boxes, so much so they have a part called an interlocker that stops it ($600 :mad2: just for the parts) Haven't driven it again since but dont expect any problems now.
On the upshifts I just back off slightly and pull it through, unless I'm warming the car up when I double clutch. Downshifts I'm still working out the best method but double clutching at the moment.

Cage scares me too. Only put it in because it was free but have regretted it ever since and I'm not driving it again until I get a proper cage put in. It is steel and quite heavy for its size so I assume its just mild steel.
Only had the wing on for the last Winton track day and I had noticably more understeer. Probably offset by more drag though!

Do have a couple but they aren't very good quality or very exciting. I'll try and get some better footage at the next track day.

Thanks. It only weighs about 1150kg so power to weight is pretty good. All times were with standard sway bars and mega understeer (especially at Winton's cleavage), hoping with the new setup to shave a few seconds.
Very tidy piece of kit there.

Bit of an update. I've been very busy at work lately but managed to strip the interior and have a cage installed. It's still at the fabricators but will get it back next weekend, give it a good clean up (can't believe how dirty the pics make it look) and it will then be off for a full respray inside and out.
The cage has gone from this:

Can't wait to have a drive to see how different it feels with a slightly stiffer chassis.
Once the painting is sorted I also need to repair the fabric on one of the seats. Does anyone know where to buy the fabric?

Cage looks decent.
Yep cage looks heaps better, who did it for you?

The cage was done by Rai Curry at Fabraications. It goes through the firewall to the front strut towers and comes with all of the CAMS documentation.
He's got a rally car out the front with one of his cages that turned itself into a ball. The passenger cell was all OK and they got out with a few strains and scratches, definately makes for great advertising!
I'll grab some pics of it when I go down there this weekend
What swaybar combo and spring rates are you running?
womblesti
07-09-09, 08:57 PM
Sorry, can't remember the specifics. I did the work over 12 months ago and have only driven it once since as I've had a hectic year at work and a new child.
All of the information is written down but I conveniently left that in the boot. :knock: I'll check on the weekend and post up the specifics.
bump for any info on your set up

Spring rates are about 500lb. I did have much lighter ones in a couple of years ago, it handles much better with the heavier springs and the lap times at winton were a few seconds quicker.
Last time I had a run it was still running standard RA swaybars. I've got a 24mm and 27mm rear bar and a 22mm and 24mm front bar, all three way adjustable, to trial next time I go for a practice.
With the adjustable lower arms I also have much greater scope for camber and toe angles on the rear as well.

I'm an idiot and forgot to take my camera. Its in the car park out the front of his shop and looks like my car's shell but much rounder!

What do you run?
What do you run?
Currently have Eibach springs with Koni inserts with a 22mm rsb
Just picked up a 22 fsb and 24 rsb both adj, fitting them up on the weekend.
Have been recommended the following combination by 2 different people:
24 F 25 R and
22 F 27 R (he did admit this was a bit twitchy in the rear)
Looking to upgrade to coilovers, hence the questions, trying to find out what works for other people.

One of the ex GTP guys I was talking to recommended a 27mm front sway bar so everyone seems to have their own opinion.
I've found the front LSD helped a lot with the understeer and the ability to add a little toe in on the rear felt good.
I've picked up a performance box so my intention is to go to the track and try different combinations to see what works and what doesn't. I've even picked up a new bootlid to try it with the WRC wing and without.
I'm by no means an expert at setting it up so it will be largely hit and miss.
Happy to share the results but how relevant it is to cars with different setups is anyones guess.

So, finally organised a week off work and have prepared the car for painting. Decided to go with Satin black inside and a green similar to Kawasaki green for the exterior, with black wheels and graphics.
Also replacing the turbo that has been a bit smokey lately. The turbo that is on it at the moment is a garrett GT30 based AVO turbo.
Anyone have any opinions on the sizing of the turbo if running a 36mm restrictor? I'm thinking a twist mount GT3088 but I'm hardly an expert on these things.
Also going with an external wastegate with V-band connections so I can easliy change turbos for unrestricted days.
Liam if you read this my understanding of the restrictor regs are within 50mm of the impeller wheel and for a minimum of 5mm. Is this correct? Anything else I need to factor in before getting one made?
Cheers

Bit of un update, car is now very green. This is off the gun so will get a polish up next week then I'll get into it and clean up the dust out of the interior.
Next week order the turbo and restrictor then hopefully get it log booked before christmas.

Thanks for the comments.
Its a Holden colour currently available on the SS. Was going to go non metallic being a track car and all but I reckoned this would look much better. :D
Looks good. How will you get it log booked for IPRA with that wing though?

Pretty sure all the Subaru stuff was listed as optional equipment on the road cars to allow this sort of shit to happen. I dunno exactly how they got around it though.
Dont think its for ipra guys....

Try Ideal seat company in vic, they are the recaro distributors. I purchased 3 mtrs for about $180 i think.

Won't be doing IRPA but would like to have the option in the future, from what I can see of their regulations the only non compliant items are the wing and tyres. Anyone know how the log book system works if you want to use the car in different classes?
I've had my spare bootlid painted in the same colour already so could use that one rather than this one. It currently doesn't have a wing on it.

as long as your car complies to the rules of the event you want to run, it doesnt matter what it says in your logbook.
Nobody can say they didn't see you in their mirrors :)

Rear of the car is all reassembled, need to do the front end then the dash and windows.
Unfortunately work is very busy so can't take days off and the car currently at a mates workshop that isn't open weekends. Makes it difficult to work on it. We'll be putting in a few days between christmas and new year to get it finished. :)

Slowly, slowly getting there. Turbo, dash and windows after chrissy.

Let me know if you want another set of those wheels :)
Looking good!!!!!!!!

Yeh the wing is an acquired taste, I still don't know if I've acquired it yet either. :) I had the other bootlid painted as well so not a difficult job changing it to go wingless or GT wing.
Looking good!!!!!!!!

At this stage it will be a GT30 of some kind, haven't spent too much time yet narrowing it down. My mates know a bloke that is supposed to be a bit of a guru so going to talk it through with him early in the new year.
Do you have any opinion on turbo sizing?
I was going to go twist mount with external wastegate but don't think I will now. I just want to drive it now rather than continuing to spending money on it :knock:
Somewhere around a gt28 is the go.

Will the alcon brakes fit under Standard rims or are they like STI brembos and you need the correct offset wheel to fit under ?

The Alcons fit under standard WRX (and Liberty) 17" wheels. The face of the caliper clears by about 2mm and the top of the caliper clears by about 1mm. I need to be careful where the tyre shops put the wheel weights otherwise they snag :)

It lives :D
Hasn't been started in 6 months and all of the wiring has been moved and disconnected by the roll cage builder so thought we might be in for a bit of electrical gremlins.
Connected everything together, hit the key and fired first go :D I know it's supposed to happen like that but it was still nice to hear it start up.
Dash has been modified to fit around the roll cage, just need to install the water and oil temp guages and the interior is pretty much done.

Unfortunately new wheels may have to wait. It appears that we will be receiving a new bundle of joy in September which means the racing master plan is in jeopardy :knock:
I'm pretty stoked though :yup:
I'll get to a few rounds of the 2 litres this year though. Profi, will see you on 2 Feb as would like to get involved with helping run rounds.

Wing will most likely be coming off as I'm not convinced either. As for the paint job being too pretty I have access to a sticker machine for zip so any rough bits can be covered pretty easily. Just thought I'd start with something nice rather than the tired +10 year old white paint job that was on it, and believe me the paint was definitely showing its age!
Also as its a dedicated track car, if I bin it bad enough I'll just park it for a while. :)
