Guest dan4011 Posted November 22, 2006 Share Posted November 22, 2006 well my motors in the machine shop, and i need to go ahead and make a decision on a piston choise, im not yet sure weather or not i want to go back to turbo or not tho. could i just throw a set of turbo zx pistons in there and use it either way, or are they lower compression pistons? any suggestions, should i use flat tops if i want to do n/a for higher compression? thanks guys Quote Link to comment Share on other sites More sharing options...
2003z Posted November 23, 2006 Share Posted November 23, 2006 yes, you can. it will have 7.3:1 compression and won't want to go much above 4700 rpms under load, but amazingly, will have a bit of low end grunt. At least mine did before I disassembled it to rebuild with better pistons. (former owner was planning a turbo upgrade, so rebuilt it with turbo pistons. I am replacing them with Nissan Motorsports Euro pistons). Quote Link to comment Share on other sites More sharing options...
Alex_V Posted November 23, 2006 Share Posted November 23, 2006 You couldnt go above 4700rpm with 7.3:1 pistons? There was somthing else wrong with your engine/ecu. You should be able to go to redline with 5:1 comp pistons. You wont have crap for power but you'll still make egnough to move the car. ~Alex Quote Link to comment Share on other sites More sharing options...

It did run a little rich though. Quote Link to comment Share on other sites More sharing options...
