has any one decided to go with a balance shaft delete kit on there lsj, i know theres a couple that have in jbodies on there 2.2 just seeing if u have any do's or dont's.

mine are pressed in now, so no more balanc e shafts for me, now time to get my car runnning

 

I'm running neutral shafts, but not much of a difference in installation compared to stockers.

I'm interested in how you "pressed" them in. The only issue I know of when doing a full delete is making sure you plug the oil holes or theres a part of the engine that will be starved of oil (can't remember which).

 

Arent the neutral shafts basically a balance shaft delete...bc they become neutral(?)

 

No its a replacement shaft thats not counterweighted. Hes talking about removing them entirely.

 

removed, u have to press a sleeve into the back part of the the oiling for the balance shafts so u keep oil pressure up, time will tell, i know it removed a lot of weight from the motor

 

What did you use to press them in?

 

when i built my LSJ, i did the balance shaft delete their entirely gone, you feel a ton of vibrations but are easily over looks cause of the performance gains

 

The performance gains are not great ~10hp. I did the GM racing kit, bushings were made and pressed in by my engine builder. There is a UK forum that showed how to get the bushings in without a press. A friend of mine did it that way

(check the dyno towards the end that showed no gain)

 

I am interested in a BSD for the LNF. I would assume its the same as the LSJ. Just a couple Q's. Is this permanent, since the bushings need pressed in?

 

whats the gm race kit?

 

IIRC the part that blocks off the oil passages is .040 oversized, so it needs to be pressed in.
