Subaru xt6 owner Posted December 4, 2014 Share Posted December 4, 2014 Hello all, I have an xt6 with the 6 cylinder er27 engine in it. The engine needs a rebuild due to major oil leakage. while I'm at it with the rebuild I was wondering, what are some options to upgrade the power of the engine. Originally has only 145hp and want to get closer to 200hp. I Preferably would like to stay away from the turbo suggestions. Quote Link to comment Share on other sites More sharing options...
Crawlerdan Posted December 5, 2014 Share Posted December 5, 2014 delta cams custom grind, intake, exhaust. larger injectors, thats about it. cams will make the most difference though Quote Link to comment Share on other sites More sharing options...
Subaru xt6 owner Posted December 5, 2014 Author Share Posted December 5, 2014 Do you know a website where I could get those parts. Parts for the xt6 and its engine are fairly difficult to get 1 Quote Link to comment Share on other sites More sharing options...
Gloyale Posted December 5, 2014 Share Posted December 5, 2014 You don't need a rebuiold to seal oil leaks. I would suggest a headgasket set.......reaseal the oil pump, and put a new Front and rear Crank seal, rear seperator seal and reseal the oil pan. If you REALLY want to improv eit a bit get new rings..... Oitherwise you aren't gonna upgrade ewasily. Quote Link to comment Share on other sites More sharing options...
Subaru xt6 owner Posted December 5, 2014 Author Share Posted December 5, 2014 Well the engine has about 230,000 miles on it so its gonna need a rebuild sooner or later anyway. I figured I'd do it now. How much more power could I get out of a custom cam? Quote Link to comment Share on other sites More sharing options...
Crawlerdan Posted December 5, 2014 Share Posted December 5, 2014 You hav to call delta and ask for the custom grind , they don't advertise er27 parts. The last set I bought they advertised 12-15% increase, intake will add 2-3, exhaust the same, get rid of cats if you can Quote Link to comment Share on other sites More sharing options...
Subaru xt6 owner Posted December 5, 2014 Author Share Posted December 5, 2014 How much did you spend on the cam? Quote Link to comment Share on other sites More sharing options...
Crawlerdan Posted December 5, 2014 Share Posted December 5, 2014 175$ I think. It's been a while and I am old and retarded 2 Quote Link to comment Share on other sites More sharing options...

john in KY Posted December 5, 2014 Share Posted December 5, 2014 (edited) If you decide swapping in another engine rather than fooling with yours, I have an ER27 engine with only 11K miles on it. Been in dry storage for years. Forgot to mention this is a JDM engine. Has more HP than the US version. How much, I don't know.
