It's one for the rear differential and one for the gearbox.

Things isn't moving so fast as I wish, but is has been some progress this week to...

Finally I've got the time to put the most of the engine togheter:

Measurring the heads so I can calculate the volume and see what cp I got after I had some work done to my block.

Check of valve clarences:

Pistons in place:

Some modified oilpump housing in place:

Block ready for heads:

Heads mounted:

Test mounting of dry sump pump to see how I should make and route the hoses:

Timingbelt in place:

Timing of exhaust cams:

The most of the work on the engine is done, so hopefully I can get it into the car this weekend.

simply stunning mate dedication to the max

Sjobing · 06 April 2009, 19:52

Engine is ready! (I think...)

I got a new idea so I had to do little more work before I could put the engine back in the car, but now (I think) it's ready to go back in...

TurboAndy · 06 April 2009, 20:31

Wow, defo going to keep my eye on this thread.

Keep up the good work.

Sjobing · 14 April 2009, 21:57

I've done some work on the car the last couple of days as well.

Engine mounted in the car:

Engine/transmission in place:

My friend is making some changes on my downpipe:

Making of the new intercooler piping:

Thats how far I got on the ic piping for now, I'm waiting to get my new trottlebody from the machine shop so I can make sure it will fit togheter.

I also made the exhaust 99% ready but I forgot to take any pictures of it today.

Great project thread! You're using some top of the range stuff m8. If you're stuck for parts contact Mark at Lateral P - he's helping me with my parts and has lots of contacts.

**STI_Baly** · 14 April 2009, 23:45

Indeed a build to follow, love the car mate keep it up!.

Thank's for the kind words!

I try to make this build as reliable as possible, and that what I try to make the right choices for.
The circuit races I participate in with this car is about 45 to 55 minutes long, and this is not kind to the car...

So hopefully it will keep togheter well this season and I can get some time out in the fresh air and not in the garage all summer.

is there any links to the series you race in mate? any more pics

Sjobing · 12 May 2009, 19:49

Hi, no I dont think there is any god sites about this series I race in. This is a new class that started last year and there is not so much about it on the internet yet.

There has been some progres, but it's so much to do at work now so I don't have to much time in the garage.

Turbo restoration:

The turbo got a new center piece, becouse the old one got slightly damaged under last season.

Exhaust ready:

The exhaust is made form 3,5" to 2 x 3" in the rear. Hopefully this will give good flow and be quiet enough...

**mneame** · 15 May 2009, 20:31

exhaust looks interesting and nice to see something different. any pics of the exit?

**trails** · 16 May 2009, 12:30

what a car, this really is a no expense spared build...is that a Cosworth IM, what size TB are you going to be using?

**B0DSKI** · 16 May 2009, 14:03

Totally stunning attention to detail

very nice, you may be interested in post #263 here then; eyebal mes neu ingine -no disin it -enit

Sjobing · 21 May 2009, 22:11

Things are moving (slowly) forward:

Engine bay 98% complete, I'm just missing an airfilter and some hose for the cooling water.

Transmission cooling, fuel and oil system completed:

The start of a new center console:

Hopefully I can finish the center console and the rest of the wiring this weekend

**bioforger** · 21 May 2009, 23:44

That engine bay is brutal

Here's a link to some pictures of the first round of the series this year:

Special Saloon Norge • View topic - Bilder fra NM/NC runde 1 & 2 Våler

I didn't participate here becouse I didn't manage to finish my car in time.
Hopefully I will be ready for the next race in the beginning of June.

Sjobing · 23 May 2009, 19:39

Just a few more wires to sort out, and I will be ready to start some testing to see if I've done everything right.

If everything goes my way tomorrow and I dont't run into some problems can I hopefully do some testing in the evening.

Sjobing · 05 June 2009, 23:40

There has been some progress the last weeks, but things takes a lot more time than I wish it should do...

Centerconsole is 97% finished:

Some initial tuning:

Yesterdays result on the dyno:

This is first adjustment so i can put some miles in it for brake in on a safe level. Boost is about 17 psi.

Peak power at 6950 rpm: 415 kw (565 hk) @ 17,2 psi boost
Maks torque: 580 nm v/6330 rpm.

When I've put some miles on it I will do a new tuning and try with 25 - 27 psi boost. I will also moeve the rpm limit to 8500 or 9000.

This is a conservative reading dyno, my car had 227 ps when it was stock and a new 2009 STi had 257 hp on this dyno.

**mneame** · 06 June 2009, 14:11

looks like it's coming along nicely.

Sjobing · 06 June 2009, 22:16

I had a few hour's in the garage today as well, and now it starts to look like a car again. . .

Hopefully I can get the rest togheter tomorrow so I can make a test run.

71/200 · 07 June 2009, 12:28

Amazing work, just a few £K thrown into that car lol

Sjobing · 12 June 2009, 21:50

Here's the latest week's progress to get the car ready for a big tracday event in the north of Norway on Artic Circle Raceway.

This event last for 3 days and the track time is from 9 am to 11 pm each day so you can drive as much as you want these days for about 90$.

My only drawback is that I live 1100 km from this track...

Making of skidplate under the drysump:

And then I modified a Cusco undertray to fit:

The car is almost finished:

Rear end:

Wheel alignment(taken 1030 pm wedensday night at a local shop):

Enginebay completed:

Car on the trailer, ready for a long trip to ACR:

Parked in the pitgarage after the first day on the track:

I didn't have any time for testing before I left for this event except the hour's we spent on the dyno, where everything worked fine.

Today I've had some problems with a sensor reading so the car won't run properly over 4500 - 5000 rpm. Hopefully I can sort this out tomorrow, so I can get some full speed rounds up here on this track.

**coops78** · 13 June 2009, 15:11

Awesome

Sjobing · 15 June 2009, 06:47

Here is me taking a nap in the pit, when I wait for the drifters to finish their competition:

Here is a video from the first rounds on the track after I have fixed the small problems that I've got:
