Impreza Group-N project.

Update!

So last time we removed the roof so we could start peeling of the skin of the a pillars.






But the fitment of the window was still terrible so I decided we did all this work for nothing and tear down the car even more.
Total roof replacement!!!

This guy does not have a clue of what is about to happen to him...




WTF just happened!!??



Scalped him Indian style!!




Of course the yellow car needed some more work aswell.








The cage needed some patching up too:






Made some extra gussets:









There they are, the two headless horsemen.





For the roof to fit nicely there was a lot of skinning and gutting needed:












Trial fitting:








It is close to being ready to get welded back on, the fit is near perfect!
More of that later.


The car will be about 40/45mm wider than standard so I need to adress the wheels and suspension.
It is really difficult to find out what is posssible and decide what to do.

A well known fact is that if the offset changes to much it will affect the handling of your car.
So how far can you change it without negativly influencing the handling, and the latest I have heard is that with my 2005/6 STI hubs (114.3x5) I can go from ET53 to ET35 maximum.

That means a 18mm gain outwards, and I want to have wider wheels than standard, maybe 9 or 9.5J wide rims.
If I would choose 9.5J I will gain an inch of width outwards again, that is 18+25mm so 43mm, that just might be the ticket.
If it is in fact possible to have an ET35 offset and still have the car handling well this would by far be the best option for me, because anything else will involve making new lower wishbones, new drive shafts etc etc, loads of work!

I will investigate more on this, becuase I want to be 100% sure the car will handle the best it can.

Anyway, a set of camberplates won't hurt anything:






While dicking around the car looking for more damage we actually did find some more:



Brilliant!

I already had the fiber 22B rear quarters but I never felt comfortable with them, because in the end they will crack when they are glued to the car.
So I bit the bullit and ordered a set of steel rear quarters from a guy in Croatia, a real master in panel beating.

It will be a mix between 22B and WRC, so a larger wheel arch and the WRC steel sills incorperated.

He sends me pictures of the progress every one or two weeks:












I am REALLY happy with them, as you can imaging.


More when there is more to tell!

[robokill]

Tops really nice job there!

[oldskull]

the panels look very nice! masterpiece!

Well, the roof is on!

I am also working on this, I drew it on Inventor.




And news on the rear quarters, they are almost done!!











More later!

Looking good, keep up the progress, it's going to be a beast.

Looks like a lot of work. Great skills have to say

Nice project!

Only a remark...the TPS at the pedal box, if it's the tps to be used by ecu for enrichment and load calculation, then it's a bad idea, due to the cable slack.

I suppose it's for some kind of data logging? or you are going drive by wire? What ecu you will use?

Hi Mech

It is the orginal tps frrom the Impreza, and when I drove the response was as good as a cable driven throttle.
This sensor always sat on the throttle pedal btw, I didn't move it from the engine to the pedals or anything.

So yeah, this car was always a dbw car.

It will be mapped on the stock ECU via EcuTek, this program works best for me.

Thanks.

Hi guys,

After wasting another year, let's pick it up again.

Replaced the rear left box section with the on from the silver spare chassis.















Why not put in some better bodywork aswell.









Then this arrived from kroatia:






And these from Japan:




So I started with the inner tubs:
















I am not even close to beeing a pro at this so I am satisfied with how it turned out.

With the fenders and new wheels:
