difference between G16A and G16B?

[speedracer006]

sorry guys, wanna do a 1.6 conversoin from my 88 sierra, just need 2 know where to start.

and input is much appreciated

cheers

g16a carby 8 valve
g16b efi 16valve - much better

thought so cheers

There is also a g16a throttle body injected motor and a port injected version the same as the g16b

Can't remember the REAL differences between G16A and G16B, but it is NOT 8v/carb vs. 16v/EFI.

I've seen several different G16A's running MPFI, Throttlr Body, Carb, etc., etc.

The blocks are all the same between the years......

G16a is avalible in 8v carb , 8v TBI and 16v multi point efi . The g16b is 16v efi , has slightly different wiring and sensors are in a different place on the efi manifold . The later g16b had crank sensors etc but these were in the sedans etc and at some stage they went to coils on plugs .

ive noticed a few import G16A's that are MPFI,

G16B's have notched pistons to allow room for the valves to drop without hitting the pistons if you get the timing all wrong

8v have 4 counter weights on the crank vs 8 on 16v but thats about all I know.

The whole G16a / b thing can be a bit misleading. Don't worry too much wether it is a G16a or G16b.

The options you have to choose from, going from easiest to hardest (and worst to best) are:

1. 1600 block with your 1300 head and carb. Pro's - easy install, con's - least power of all 1600's.

2. 1600 8 valve carbed Vitara engine. Pro's - easy install, no wiring etc, con's - again, power - less than EFI versions.

3. 1600 8 valve TBI (throttle body / single point injection) Vitara. Pro's - EFI! more power. Better off idle torque than 16 valve (good offroad), but less power. Con's - wiring to install, less power than 16 valve

4. 1600 16 valve multipoint injected Vitara. Pro's - EFI, most power. Con's less off idle torque, wiring to install.

5. 1600 16 valve Baleno engine. Pro's - late model engine, EFI, power, low manifold height means good bonnet clearance. Con's - same as 1600 16 valve Vitara, plus water pipe fabrication required to get water from back of head to radiator, or use Jimny manifold.

They are all much the same to physically install. All require sump swapping and oil pickup cut & shut. The Baleno also needs a crank angle sensor in the front of the sump - another cut & shut job.
All need the 1600 narrow body starter and 1300 clutch.

Obviously the EFI ones need a bit more work sorting wiring and installing high pressure fuel pumps, but its well worth it in my opinion, EFI drives so much nicer.

PM me if you want an adaptor kit My adaptor works for all these engines. See the pic in my sig.

ummm...yes it IS!.......16b is aussie spec for 16 valve efi, not jap spec.
