93B17A

just thought i would let people know first hand they don't work, even though eagle claims the ls rods will work. this is totally untrue, yes the do have the same crank pin (1.772), piston pin (.826), and b.e. width (.935). however the c-c lenths are different, on the eagle rods it is 5.394, but the B17 rod has a c-c length of 5.208
i found this out today when putting my block back together, the piston stuck out of the sleeve about 3/16". now i have to spend the extra money to get crower rods

Bummer, man. I'm sure someone will pick those rods up from you though.

Yep, had the same thing happen to me a couple weeks ago. I had a couple posts up about the problem, too bad you didn't see it and you might have been able to avoid this. Where did you get the eagle rods from?

93B17A

i bought the rods back in january........from jeff at import builders

Aeka GSR

id let eagle know that **** doesnt work.

according to eagle there are two different models of the b17. the earlier models have a shorter deck height. the later ones have the same deck height as an ls 1.8
they can not tell you when the switch took place.they suggest disassembly of the motor first and measuring yours before ordering.

I got the same story from Eagle about two different blocks being made with different deck heights. I would really think that if it was true, something would be mentioned somewhere in the helms manual. I've been through that book so many times I certainly would have seen it.

speedworks

i agree, but that is there story

dustin

Heh, there is only one version of the B17.... sounds like a "cover up" story to me. Isn't it just the B17 crank that causes the problem ?

93B17A

yeah i have both a 92 and 93 B17 cranks, rods, and blocks. they are the same..........like dustin says "sounds like a cover up"

"Yep, had the same thing happen to me a couple weeks ago. I had a couple posts up about the problem, too bad you didn't see it and you might have been able to avoid this" Brian_92GSR

by the way what kind of rods did you get instead? and hows your set up coming?

Well on a side note, I'm looking forward to building my '93 B17 sometime soon too.. any suggestion on rods that fit??

ENDYN

Endyn just made pistons for a friend so he could use the B16 Eagle rods in his B17 turbo and they're supposed to be a stock item now.

B17A did have 2 different deck heights, don't know what years tho.
1- deck height = 8.014" which uses the B17A only rod 5.208", r/s ratio 1.62-1
2- deck height = 8.200" which uses the B18AorB sized rod 5.934", r/s ratio 1.68-1

Stock deck clr for either B17A is .026"

B16A rods are 5.290", .082" taller than your stock setup.

You need a taller block or custom pieces.

Best bet would be to buy a B18AorB block and have it bored, honed, and use the components you already have. Probably cheaper than custom rods or pistons.

I ended up going with Crower rods. Everything ran pretty well for the week I had it working, then some valves hit some pistons on Monday night. I'm going to replace the valve train and get some head work done now.

i don't think so cause i have my 93 B17 that i'm working on now and i have a spare 92 B17 on the side and the rods pistons and crank are the same
