i'm asking because i'm planning a rebuild w/ je pistons and crower rods but was wondering if the tolerances were very close...

 

Crowers come balanced already. Not sure about the JE's...

 

thanks vaportrail,well after making some phone calls and seeing what a dent all the materials are going to cost ive deciced to go w/ EAGLE rods instead. not a bad compromise.

my concern is the balancing of these components,has anyone in here dropped some rods/pistons in w/ out having them balanced?

im basicaly doing a standard rebuilt w/ aftermarket rods and pistons,and MAYBE (BIG maybe) sending the head off to portflow (depending on if i get my raise)

the setup will be:

95 GSR motor
DRAG 3 kit w/ Tial wg
JE pistons-EAGLE rods
portflow head w/ titanium valve srings
440 cc RC injectors
Hondata stage 3b
Bosch fp
Greddy ebc
Greddy tt
Greddy A/F gauge
CM stage 3 w/ JUN 10lb fw

i'm trying to make it as reliable as possible,thats my main goal.(10-12 psi reliably) i'm tearing down the engine soon anyhow thats why im going w/ the upgraded internals...

sounds like a good setup. If you can't afford the head work, try a skunk2 intake manifold on there, it makes good power!

 

you know i like the gains ive seen w/ the skunk manifold but the drag piping i bought is for a gsr. id like to redo the head anyhow (just a matter of time and money) cause the motor has about 100k miles.

 

Aftermarket parts are supposed to be balanced, but there is a small error and when you combine it with the bearing, rod/piston, wristpin and ring pack you can get a setup that's more than 1.0 grams off of one another.

I picked up an analytical scale and a rod balancer (looks like a seesaw), about $400 for the pair, probably well worth it because getting a shop to balance your parts is $$$$. Though you'll still need to have a shop balance the crank.
