can any one tell me...?


Thanks Fluffy

[tanshi]

in short, G16a is a carbie motor
g16b is efi

[Fluffy]

hmm but physicaly...
will a g16a head bolt to a g16b
will a g16b bolt up to a g16a bellhousing mounts.
will a carbie manifold bolt sraight up to a 16b?

[tanshi]

I think the bell housing pattern is the same, ie will bolt to the same gearboxes. I dont think the head patterns are the same, and im not sure why you would wanna bolt a carby head to an efi block

[Fluffy]

just purely to satisfy my curiosity...it seems 16bs are abit easier to get hold of
I found a little bit of info
HERE on outerlimits

[royce]

I have 16valve G16a at home so thats incorrect

I dont know the exacts of it all but may be something to do with years like the G13a and G13b

afaik its all mostly interchangeable

Suzuki Engine block and head data: G13- G16

This information comes from many posters world wide. Not me.
If you find an error, please contact me.

G16A = Made in Japan actual. ( surely isnt number of cams or valves)
G16B = Made overseas (not Japan)

The 16V DOHC swift GT , had forced everything: pistions, rods, and crank.
The non GT has nothing forged.
The G16A heads are weaker.
The G16B crank has counterweights on each lobe , unlike the 2 ends of the former. Better crank.
The Crank and cam are hollow, on many. ( so called weight savings).

The back of the bock is marked G16A and has no meaning at all , A or B.
The vehicle will have a plate showing the truth. A or B. Same plate as color code and veh. weight.
The engine serial number will say G16B too , if it is.
The G16A /B bocks can have a number of different pistions, 2 or 4 dish valve slots.
All regular G16A/B engines have weak cast rods, (except GT variant). (Turbo issue).
All G series blocks are very strong, thanks to their pressure die cast design and webbing.


Oil Sumps and pans vary.
-----------------------------------------------Heads----------------------------------------------------


The G16B 16V SOHC head has more casting webbing than the G16A SOHC head has, all heads are essentially interchangable between the G13A/B G15A and G16A/B as the bore variation is so minor, the G13B 16V head is the same head found on the G16A/B; it even has the same Casting numbers in it, from the molds used.


-------------------------------------block raw data -----------------------------------------------

G13/16 - 84mm bore spacings

deck height (block height)--------------
Suzuki G16 = 215mm
Suzuki G15 = 205mm
Suzuki G13 = 200mm?


Main journal diameters---------------
G16a/b = 52mm

Crankpin diameters-------------------
Suzuki G16a/b = 44mm

Rod Lengths --------------------------
G16= 138.5mm

Valve sizes ---------------------------
G13/16-a/b/bb SOHC 16v all same
G16 16v
inlet = 30.1mm X 5.5 X 92.3 1R
G13b 16v
inlet = 29.1mm X 5.5 X 92.3 1R
exhaust = 24.9mm (all 16v)

capacities------------------------------------------------------------------
G13B and BB
1298cc - 74mm bore x 75.5mm stroke
G13A?
1324cc - 74mm bore x 77mm stroke
G15
1493cc - 75mm bore x 84.5mm stroke?
g16a/b
1590cc - 75mm bore and 90mm stroke
90mm stroke is not a problem:
The fiat and lancia engines have shown this with their 10,000rpm 90mm stroked 4 cylinder engines.

Crank-----------------------------------------------------------------------X
Stroke
G13B - 75.5 and 77mm (forged and cast respectively)
G13bb - (cast with solid journals - very strong compared to hollow)
G16B - 90mm (cast with hollow journals)
G15 - 84.5mm? (cast with hollow journals)

Pistons-----------------------------------------------------------------------X

Gudgeon pins
All 19mm ?

Piston Pin heights-----------------------------------------------------------
G13b 29.1 mm
G15 ??mm
G16b 28.5 mm


Engine weights-------------------------------------------------------------X
G16b = Total 131.75 lbs 60kgs!

G13B crank has a 75.5mm stroke, 45mm mains, and 42mm rod journals?

update: g16a/b block height 215mm
measured from crank centerLINE , to deck

is a 16 valve cross flow?

[royce]

they all are

[cj_zuki]

Most refer to the 8v carby engine as a G16A and the 16v efi engine as aG16B even though you can find G16A on the 16v block. As mentioned the 16v has a better balanced crank and the pistons are different to suit 4 valves per cylinder instead of 2.
