Subarian Posted February 13, 2006 Share Posted February 13, 2006 I know some of you have done this. I've got a turbo motor I'm thinking about putting NA pistons in for better bottom end. Have you run into any issues running stock boost, like shortened life or need to buy premium gas? Link to comment Share on other sites More sharing options...
calebz Posted February 13, 2006 Share Posted February 13, 2006 I used the whole NA shortblock with mine. It goes pretty well.. Has aabout6k miles on it like that.. Premium gas? I have driven mostly turbo cars for the past 10 or so years.. they alllll get premium Link to comment Share on other sites More sharing options...
Subarian Posted February 13, 2006 Author Share Posted February 13, 2006 So what did it do for your performance? Link to comment Share on other sites More sharing options...
Subarian Posted February 14, 2006 Author Share Posted February 14, 2006 Bump. I really want to know if it's worthwhile. Thanks. Link to comment Share on other sites More sharing options...
calebz Posted February 14, 2006 Share Posted February 14, 2006 Hard to tell what the improvement was. I did the shortblock, Intercooler, TD04 and 2.5 inch TBE all at the same time. As a whole, it kicks rump roast:D Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted February 14, 2006 Share Posted February 14, 2006 Even with 7.7 pistons you need premium gas. Im in the middle of building my EA82T using a N/A block. Hopefully, if all goes well, i will be dropping the motor back into my RX and i can let you know what kinda difference its made. -Brian Link to comment Share on other sites More sharing options...
MilesFox Posted February 14, 2006 Share Posted February 14, 2006 i would go the route of using a n/ block. less work and likely less stressed as well as far as carb and spfi blocks go you will have to bypass the pcv outlet on the back of the block because its not present on spfi and carb if you were to find a n/a xt motor with spider intake , the block WILL have this pcv the knock sensor will fit on the carb and spfi as the threaded hole is present my buils was on a carb block 9.0 compression. ported heads and stock management. regular 87 octane and 20-23 deg tiing caleb has pretty much the same build withthe carb block Link to comment Share on other sites More sharing options...
