would it be safe to bore out my motor to 84mm on stock sleeves for a semi daily driver. this is wut my block has:

ls block

acl bearings
block guard
main girlde kit
itr oil pump
arp rod bolts
arp head bolts
balanced crank shaft
p30 pistons

stock b16 head
chipped p28 ecu

 

How are you going to use P30 pistons with an 84mm bore? The P30's are 81mm pistons. Honestly, I'd spend the money to get the block sleeved.

 

You will need aftermarket pistons and sleeves for an 84mm bore.

 

sleeve it....

 

You got alot to learn kid, you cant bore an ls to 84 mm on the stock sleves, nor can you run a p30 piston in an 84 mm bore. Send you block to bensons, golden eagle, or rs machines and have them sleve and bore your block set aside a grand for that. Now your gonna need after market pistons, cp, arias, import builders sd's, set aside 450-550. Aftermarket rods, eagle, crower ect 300-600. New bearings ect.

 

the p30 pistons are wut i have running in the block right now. im not planning on using those pistons cause i know they wont fit.
