Re: 1300cc swift twin cam , what I need?
They are not the same, although the blocks may be dimensionally the same. The dimension I haven't
been able to confirm is the mains on the crank. This informaiton is to the best of my belief, if someone
can confirm or correct any of this please do so, but please have a reference.
Generally, (with at least one exception...) (1.3 bore = 2.91(3) in all cases)
G13A cast crank, standard rod Sami (3.030 stroke) and Std swift/Geo (2.970 stroke)
G13B Steel crank, Standard rod Sami and std swift/ Geo Sami (3.030 stroke)
and Std swift/Geo (2.970 stroke)
G13K steel crank, Heavy duty rod, this is the GTI/GT block crank assembly (3.030 stroke). The
exception is in '89 (early?) at least, the GTI was built with blocks marked G13B, but were the
dual overhead cam (DOHC) GTI with the good crank and rods. Probably Suzuki using what was
available till new stock was available.
The GTI engine was built for high performance aplications and can take punishment that will destroy the
standard 1.3 bottom ends. Don't expect to slap on a GTI head and induction and run it to/past
GTI specs without risk.
