question about b18a1 motors
So I'm build LS/VTEC, but the block I bought is bare I have tore down a b18b motor but not a b18a1 I know both are basically the same.. but I don't recall a girdle being there I thought I saw somewhere that there is girdle on b18b and b18a1. My question is there? can one be installed??? what does the girdle do??

Re: question about b18a1 motors (ITRiWISH)
The main thing the girdle does is strengthen the bottom end of the block. I would think that a girdle from one B18 block might fit the next B18 block. There's one way to find out...

Re: (prplhrtcivic)
I may be wrong but I thought only VTEC engines have girdles? Are you talking about the metal plate that bolts to the main caps? If so it wouldn't hurt to get one. I know some company's make aftermarket for LS engines. I believe they help to stop the oil from air-ating or foaming.
BTW A1 and B1 engines are identical.

Re: (SirRevvs)
The only difference between a1 and b1's are where they put the radiator fan switch from the factory and even then these can be plugged/switched. Neither of these use a girdle. A gsr/type-r girdle can be used, but the dowels won't line up, so you will need a machine shop to drill out the other holes. Yes, a gsr/ itr crank will fit in a b18a1/b1 block AS LONG AS YOU USE GSR/ITR RODS , and the correct bearings
