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?

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

So what did it do for your performance?

Bump. I really want to know if it's worthwhile. Thanks.

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

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.

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
