Got round to wrapping the exhaust this weekend, which is always a nasty job… the glass fibres in this stuff go everywhere no matter how careful you are, but it’s worth it once it’s done.
The main aim was to protect the Carbon Fibre Propshaft, especially the U-Joint connections from heat, so fingers crossed this will help.
A few tweaks to the roll bars front and rear, and we’re nearly ready for the track end of the month.
Next job is to install a 2psi residual brake valve into the front line, to help with pad knock off.

Enjoy the weekend folks!
Hey Dude, its been a long time. I just came back to this thread to remind myself of your car.
Hope its still going well? Whats the latest update?
Apologies for the lack of contact, and not replying sooner…
It’s been a very busy few years, with job changes, some health challenges and many projects on the go at once! I think I can see some light in that tunnel, either that or a train!! 🫣
I’ve decided to go all in on the Impreza, and embarked on a journey of design and development for a full carbon fibre time attack kit. This will include all standard panels replicated in carbon (roof, doors, bonnet & boot etc), then the purpose designed bumpers, front/rear wings/fenders, side skirts, front splitter and rear diffuser.
The design is nearly complete, just a few manufacturing tweeks to do and I can begin to create the plugs. I have included a couple of CAD shots… let me know your thoughts? (Ignore the bonnet scoop, just haven't got round to removing it)
Well hasn't this project escalated?!
Looking incredible too. Its a bit like a hybrid of Gob Stopper and Richard White's Time Attack GC8.
Do keep us posted on progress please. Unless there's another way to follow along like instagram or youtube?
And yes Jonny, I will be keeping a picture/video diary of the whole process… and hope to update a YouTube and Instagram channel, will post links when they’re up and running. 👍🏼
The concept is actually based off the Tilton Evo… I do like that car!

Well consider me subscribed once you've got your media channel up and running.
Thinking of doing an insta and YT series for my V8 Volvo 240 build I'm just starting. Nervous about being on camera though!
Was looking at your models again, and I was wondering if the opening for the intercooler might be a bit big? I know its not the final design but thought I'd throw in my 2p out of interest.
Now I'm not an aerodynamicist, and by the look of this project so far I know you know far more about it than I...
But with a big opening for the heat exchangers, the air wont be slowed down at all and I believe the ideal design principle to follow is to try and slow the air (or water!) down through a heat exchanger. So it can have longer to do its heat exchanging.
By ducting the incoming air from an opening about 30% the size of the heat exchanger it will slow the air and improve its effeciancy.
I've just dug up some videos that explain the theory and application far better than I can!
Yeah, I’m not sure about being on camera either! Sounds like an interesting project you’re about to start, have you moved on from Subarus or just expanding the stable?
Well spotted on the intercooler opening, you are correct regarding air flow through heat exchangers… which is why there will be a separate insert fitted to the intercooler opening which will reduce the inlet size and gradually increase it leading up to the core itself.
It can’t be part of the bumper as I wouldn’t be able to release the part from the mould, hence it will be a separate part. Just haven’t finished designing it yet!
The openings either side of the intercooler will be for an engine oil cooler and gearbox oil cooler.
Hi Kim,
I was 99% you’d have considered the ducting. But thought I’d mention it as there’s often lots of people silently reading build threads, looking to learn things.
Don’t worry, I’ve still got the subaru’s* too! Can’t imagine ever selling the classic.
This summer was its first time back out on the roads and track after a full strip down and nut & bolt rebuild over 2 years;
Welded in new cills, arches, rear turrets etc and all the suspension was re-powder coated.
But the biggest thing was slotting in a fully forged 2.1 and 6speed box.
Paired with new RCM headers, a SC42+ turbo, Full 3” cobra exhaust with a cat, Link G4+ ECU, and a new intercooler/ rad / oil cooler package.
So its now running between 380-450 bhp depending on the map selected and it just eats up the miles on track without overheating like it used to.
*Pural as my daily driver is a 3.0R Spec.B Legacy wagon. Might sell this soon though as I need a van for other hobbies.
As for the Volvo, that’s going to be my ‘sleeper’ car for shows, road trips, run what you brung etc.
I've actually just taken delivery of a Haltech VCU for it, so its getting quite exciting now!
New Exhaust Time!
