leesfer Posted February 26, 2012 Report Share Posted February 26, 2012 What's the logo on the bottom of the piston? Looks like there is something under the rod there Quote Link to comment Share on other sites More sharing options...

leesfer Posted February 26, 2012 Report Share Posted February 26, 2012 If they were Wiseco, Ross, JE, etc they would have the logo stamped on the bottom there You might be in the same boat as me, I still haven't figured out what my pistons are... Yours look like they are forged though Quote Link to comment Share on other sites More sharing options...
89BananaQuest Posted February 26, 2012 Author Report Share Posted February 26, 2012 Yea, well then its just the issue of how far do i push them? Quote Link to comment Share on other sites More sharing options...
leesfer Posted February 26, 2012 Report Share Posted February 26, 2012 As long as your tune is good then push them as far as you want If you are TBI then you won't be able to push them to their limits anyway, you'll maxing out at some where around 350WHP I'm going to be pushing my hyper-u's over 400WHP but as long as the tune is spot on, there wont be a problem Quote Link to comment Share on other sites More sharing options...
Indiana Posted February 27, 2012 Report Share Posted February 27, 2012 What goes here????http://i142.photobucket.com/albums/r120/mattwallace6/677d105d.jpg Those four circular points were likely some mounting point that had to do with it being machined at the factory. http://www.b2600turbo.com/images/82heads.jpghttp://www.b2600turbo.com/images/82paint.jpg Quote Link to comment Share on other sites More sharing options...
89BananaQuest Posted February 29, 2012 Author Report Share Posted February 29, 2012 Ok. What about tthat lil spot that looks like it would have something bolted to it? Thats exactly how it looked when i pulled the pan. Also with the talk of not knowing what the pistions are, but that the bottom end and crank are balanced i really wanna know how far this can be pushed and what exactly it will take to get it there?

Frenchi934 Posted February 29, 2012 Report Share Posted February 29, 2012 thats for the oil pickup on other models of the g54b... but what im wondering... wt.... happened to the rod caps on cyls 2 and 4...?? Quote Link to comment Share on other sites More sharing options...
89BananaQuest Posted February 29, 2012 Author Report Share Posted February 29, 2012 I have two friends who are mechanics at a local dealer ship and i have had both of them look at it and they said that it looks like the bottom end the rods were balanced. And from my reading and people i have talked to thats the common consensus. When they balance the rods they have to grind them down to make the weight equal. The crank counter weights have had the same thing done to them. I can get some more pics if need be. What i saw weird is the pistions are out of order. A,c,d, then b... Not sure if its something to do with balancing or not. Quote Link to comment Share on other sites More sharing options...
Frenchi934 Posted February 29, 2012 Report Share Posted February 29, 2012 ahh i see, if thats the case (and it was balanced) im sure the pistons being in a different order is part of that process. Quote Link to comment Share on other sites More sharing options...
89BananaQuest Posted February 29, 2012 Author Report Share Posted February 29, 2012 Yea, Thats what im going to assume. That the abcd was part of the manufactuer markings and that who ever put it to gether re arranged them as part of balancing. But what i cant figure out is the pistions.... Mitch looked at it when he came to pic up parts and said they look like his wisco's and that his had hand engraved numbers.... Any one know if this is true? Also does any know know any thing about the number on them? I just wanna know what i have and what i can put to them. Dont wanna get it back together and push it past its breaking point. But i wanna be able to get the most i can from it. Quote Link to comment Share on other sites More sharing options...
