jeep zj stroker build
Posted: May 7th, 2023, 2:53 pm
So i have decided to build a stroker for my 95 zj with ax15.
Im looking for some guidance because i have a general idea of what i have to do to build the jeep however i dont know the small details i need for it to run as i want it to.
I am looking to go to a 4.6-4.7 liter stroker. Im not looking for crazy performance or anything special, reliability among everything else. I am also wanting to be able to run from regular gas to premium without the chance of predetonation.
The main confusion i am having revolves around compression ratio and if im going to bore the cylinders to .30 over or not. Again im going for compression ratio so i can still run regular gas.
Here are a list of parts i have for it right now:
-Block is from a 96zj
-Head is brand new with rods and rockers from a 95ZJ
-crank shaft is a scat series 9000 SCA-942010 with a 3.895in stroke https://www.summitracing.com/parts/...H ... -vCcQJRfyI
-pistons are for a 4.2l and are sealed power SLP-470AP 3.750in bore pistons https://www.summitracing.com/parts/slp-470ap
-i have 4 hole injectors and accel ignition system for spark and fuel that should work well
Parts i still need:
-cam shaft is brand new factory cam however im thinking about getting an aftermarket one that will mesh well with the new stroke. However i dont know which one i should get becasue again im not looking for anything crazy just something that will help with the stroke
-piston ring/seals: i will probably stick with the same sealed power brand so it will mesh well with the piston however i dont know what bore size to get especially if i bore .30 over or not.
-piston rods: i may use the factory rods out of the block however i dont mind getting new ones while i have it all apart just dont know what brand or choice will be good.
-bearing caps: i just need to know what a good brand to choose would be again nothing crazy just something i can rely on.
Any help or information would be great, and if there’s any vital info im missing just ask. Again my goal isn’t for some crazy monster just some good torque and power while being the most reliable.
