LS1 and LS2 Injector O-ring Confusion (Manifold) Hey,
I bought the kit from CBM and noticed a possible issue with the O-rings.
http://www.ebay.com/itm/221103821632...ht_2040wt_1161
Comparing them to the stock LS1 O-rings, CBM O-rings are thicker as described in the auction, but the inner diameter is smaller that the LS1 stocker and the outer diameter is the same. My research tells me the LS2 O-ring is about 15.5mm in diameter vs the LS1's 14mm.
So I beleive the correct injector O-ring should have the the same outer diameter as the LS2 O-ring to run it on the LS2 manifold. Is this assumption correct?
Also My LSXR manifold came with O-rings aswell. They have the same inner diameter as the LS1, but a larger outer diameter...
Does CBM have this O-ring wrong for LS2 applications? I'm just not sure which O-rings to run...CBMs retro O-rings or FAST O-rings.
