Do Eagle and JE make specific pistons for the b20?.. Or will i have to use the b18b's.. will they even fit?.. Will most parts required to build up a b18 be interchangeable with a b20?.. Thanks.

 

the rods are the same as an LS. I have a set of LS Crower rods if your interested. Barly used, ARP rod bolts included, 400 shipped

 

JE 9.1 Piston and Eagle Rod.

Rods for the B20B is the same as the LS, since they have the same crankshaft. So anything B18A/B will work. For the piston, JE/Arias/Ross/Wiseco all make the 84mm.

 

JE makes a decent number of shelf pistons for the B20. The three compression ratios(9:1, 10.5:1, 12.5:1) come in 84, 84.5, and 85mm bores. http://www.jepistons.com

 

Rods are the same pistons are diff. LB18-81mm and B20--84mm


B20B bare block---$500---have stock pistons and rods.No Crank

Used Endyne pistons 84.5mm(12:4.1)on Eagle rods (LS). 5,xxx miles on them---$650

 

just keep in mind that JE's part numbers and compression ratios are configured for the combustion chamber of a b16/c5 head with GSR head numbers will be appx .2 higher and a little lower for stock head configuration. we've got the stuff just not allowed to post on this site for some strange reason so i won't kick out any numbers
thanks,
