Hi everyone ok I rebuild my enging something went wrong! now i got a hole in the engine block im having a hard time findine a block is a G13A is there maybe another block I could use! I'm on a budget.

If you're planning to rebuild your current engine into another block than I think you'll need to stick with the G13A.

Alternatively - you could probably use a G13B/BA short block - which will bolt up to your transmission and can use your clutch, head, etc.

The difference between the two engines is that the A is a 74mm bore x 77mm stroke giving 1326cc and the B/BA is 74mm x 75.5 giving 1298cc.

OK! but the blocks are the same? I'm going to use everything from my engine, I just need a block.

No, they are not the same...  One uses a LONGER stroke to make more displacement.  If you try and use shorter rods in a longer stroke motor, you won't get the compression needed to fire.  If you try to use longer rods in a shorter stroke motor, you'll destroy pistons and probably heads, rods, crank, etc...  Other than that, you should be OK...

A block out of a 1.3 Geo Metro will work.
