Thanks Guys If you read my thread, then the build is strong enough for about 550 brake Currently running around 360, but pushing for around 430 on a budget. Got a great mechanic at Predator, and Im sure he will see me fine! (Really good!!) Just wondered what anyone else is running - as apparently Subaru will not produce anymore of the STIs after the end of 2018!! Cheers all

Who's running big, and what is your build?

very nice!!

Again, havnt made up my mind yet, but the engines built for a good 500 + I ran one some 10 years ago at 400 and that was fun. Been in HSVs since then and just returned to Subaru, so any suggestions welcome!

Havnt decided yet. Only changed the pipes from front to back, AEM intake and remapped for now - need to be careful running in first! suggestions? cheers

Sounds good! Strengthening done - Closed deck Mahle 4032 pistons New EJ257 heat treated crankshaft ACL race series main and big end bearings Williams H beam rods ARP head studs new 11mm oil pump Cosworth head gaskets high capacity EJ20 125 sump EJ20 oil pick up pipe RCM sump baffle plate up-rated Exedy clutch Hoping this will do the job!

Yeh< painful Tokyo cheap engine!! have to spend so much money to build a decent strong engine to run reasonable Subaru power!!

Up and running in - and looking good! Wondering if anyone else has embarked on a build yet, and what you have gone for? cheers

Hello All Wondered if anyone has changed their air filter yet - and what you think? cheers

10 years ago I was running an STI which I gave to Zen Performance to up-grade after blowing the original engine. We went for a 2.5 version with larger Garret turbo, 650 top injectors, forged pistons/rods, de-cat pipe and re-map - and it made around the 400bhp mark. That was a pretty quick car!!

Just saying hello - although technically my new 2015 WRX STI isnt called an Impreza anymore!! Any advise on power up-grades and who you have used for what gains would be very welcome thanks Stubbsey

Rubbish!! I just got the same reply when I asked if they had a test car on the go!!

Exactly!! Facebook Subaru Uk and let them know your thoughts via messenger

Still worth badgering Subaru UK to get the Pro R 340 up-grade approved by Japan!! Basically the same engine that has been approved on the last few years models, and it means you keep your Subaru warranty!! surely it can only be a matter of time?
