Rallycross supercar build - gc8

sihorton

Well i thought it was about time i put up some information on my current build project for this year.

I'm in the process of building a supercar class rallycross gc8 impreza for the british rallycross championship. The collected the donor shell about 7-8 months ago, but due to incidents last year the time scale got put back and back and back. But now we are well and truely on with the project and only 63 days to the start of the new season, so it's all hands to the pump and time to burn the midnight oil.

The basic spec will be to use a 2ltr closed deck to produce circa 500bhp, but we will be less to begin with till we get the car through it's first few events and we learn to drive the thing , PPG straight cut dogbox, 4.44 diffs, proflex 3 way adjustables and a set of big balls!!

Various members of scoobynet have been helping me and are awaire of the project, and i've no doubt i'll be calling on the help from some of the others over the coming weeks.

We are turning this..


into this..


The car is being fitted with a complicated rear radiator system which has take quite a while to figure out properly, but is almost finished now. This has been done to reduce the chance of front raditor damage, which does happen due to the nature of rallycross.

This is were we are at the moment with the inside,


and from the front


As i said, there is a lot of work to happen in the next few weeks, but watch this space as i'll keep you all updated.

Really interested in the rear rad setup mate. Deffo keep us posted on that one.

Rear rad set-up looks very similar to mine, also solves the problem of the rear firewall in a wagon shell

Good luck with this, it's about time we have a competitive rallycross Scooby

Cheers for all the comments

Had another big weekend on the scooby and managed to get it back on it's wheels for the first time in months.

The prep work for spraying will take part this week with a view to having it fully sprayed by 2 weekends time.. hopefully!

Here's a few pic's of the progress.


and the rear

and the rear rad and fuel cell installation


rear rad needs the elecy water pump fitting and the return pipes to the engine bay, but give you the idea.

Going to be another busy week to say the least!

Lateral rad and intercooler combo, seperated.

Si, box is in progress, waiting on a call

sihorton

well spotted Steve. Extra browny points for you.

btw, spoke to Paul at zen about a few other bits & pieces last week, he mentioned about the box then. ta

Another weekend, another couple of milestones.

Managed to get the rear diff, shafts and hub's finally sorted.
Had to fabricate our own brackets for the wilwood rear 4 pots as they where designed for r160 rear hub's rather that my larger r180. However the work is now done and they look the mutts nut's, hopefully they will do the business on track, going to get a hard life with the flyoff handbrake!




The rear door vents and roof vents got a final layer of filler to smooth them perfectly to ensure proper airflow into the rear rad. The dimensions for the rear NACA ducts where taken from official aerodynamic documents and scalled up, so they are not just big holes in the back doors





Also fitted the adjustable rear tie bars, slightly larger rear ARB, h/duty droplinks and now we are all ready for the proflex shockers to go up later this week when they arrive back from been serviced.



Looking to do final bits of bodywork before spraying the car, weather permitting, mid next week. Then the rear fun with the rest of the mechanical bits and pieces.

I think you'll find it will be a rallycross car

Great project, where abouts does this Rally-X take place in the UK, seen it on the tv occasionally but not aware of any meets or circuits.
