I found a guy selling b18a long rods from eagle used for pretty cheap, but what the hell are long rods for? They can't work with stock height pistons right? Is it just to give a better r/s ratio with the use of different pistons? If anyone knows anything about it hit me up b/c I need forged rods still and if I don't go with these it will prob be tuner toys for me.

oh and i've already got pistons (srp 10:1 comp for a b16, so it should be lower in b18b right??, i don't really care if its not i spose) so I won't be buying the long rods if different pistons are needed

 

The longer rods are used when you raise the deck height with a thick piece of aluminum welded to the block.

They won't work with a stock height block.

 

well thats kinda gay, but thanks

 

The Eagle Catalog shows 3 different long rod lengths for the B18a/b.

 

Longer rods change up the rod ratio. Plus with longer strokes you need different sized rods.

Dart tall deck block

 

more stroke or a raised piston pin



how much longer are they

 

5.394 Stock 510 CRS5394A3D
5.531 +.137 520 CRS5531A3D
5.862 +.468 N/A CRS5862A3D
5.967 +.573 555 CRS5967A3D
6.243 +.849 N/A CRS6243A3D

Yes, I will be using a set in a D series build once the bearings are made.

 

.137 longer. I heard back from the guy selling them finally and he said that for those rods they just sell a different height piston for it. Not a bad idea i guess for making more torque, but i already bought my pistons, so i think using longer rods would probably being pushing my pistons inthrough my valve cover

 

if you keep the stroke stock the only thing you get from longer rods w/ raised pin pistons is a diff R/S ratio.


having a raised pin on true stroker setups helps with wear on piston skirts
