Default Dominik's 2008 EUDM STi Hatch - JDM EJ207 swap

Hallo aus Deutschland

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.

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.
