Hallo aus Deutschland :wave:

My name's Dominik, located in Germany, and I'm currently driving a 2008 Hatchback STi.
Over the last 2 years, the hatch turned into a racecar. :lol:

I bought it completely stock January 2016. After a first mapping in May '16 i got the first blown engine --> spun rod bearings.

After that, we rebuilt it with some better internals, like Mahle pistons, ACL main + rod bearings, ARP head stuts,...
Together with a upgraded DW65c fuelpump, DW injectors, Blouch TD05-18G XT-R turbo we made around 400hp.

After a leaking intercooler i replaced the TMIC with a mishimoto FMIC. Some other things have also been added or replaced.
I installed a bolt in roll cage (built under DMSB license). DMSB = german motorsport association.

The car is built for trackdays and hillclimb, so the engine doesn't know slow driving and something like that. Everything was running fine till May 2018...
I recognized the engine burns some oil, more than the last 1,5 years. After a compression test, the result was 8-8.5 bar on cyl. 1-3 and only around 5 bar on cyl. 4.
Maybe ringland failure or something else, i don't know.
Now the engine is replaced with a JDM EJ207 W20C engine from a JDM Hatchback V10.

Some new stuff for the racecar :naughty:

Selfmade acrylic windows (Macrolon) with sliders from plastics4performance (UK):

I also cut out the doors and saved 3.6kg on each rear door and 4.7kg per front door.

A CAE ultra shifter found its way to the car, together with a custom centre console and 3D printed shift knob.

And i finally got my new dress, DIY cusco wrap.

so you fitted 8x18 et 40 with 20mm spacers? with AD08R in 245/40
i thought even 8,5x18 et 35 ist rly tight to manage.

rolled the fenders?

~1460kg incl. driver (74kg) and fueled up 95%.
That’s more reduction than I excepted, but less than I hoped. I love your setup!

I have a goal of getting under 3klbs, or 1360kg. If your interested, I’ll post up once I have everything back together.

Btw, how much work is installing that CAE. I have one coming, but not entirely sure what I’m in for?

Do you have any videos of you using it?

CAE Shifter is easy to install but requires some modification.
You have to extend the stick to the transmission around 45-50mm. Also the holes in the mounting plate will not fit, you have to drill new ones.

Sorry i have no video of using the shifter.
