Outer Limits 4x4 Board

Hi guys, I did a quick search but didn't come up with what I was looking for.
Has anyone put a the standard G13A head on a G16B block?
I currently have a bone standard G13A naturally aspirated engine in my Sierra, and am looking to gradually upgrade to a 1600cc engine.
$$ is a bit tight at the moment, so I was thinking I would initially use the 1600 block with the 1300 8valve head (carburated), and then as money allowed, switch to an EFI set up with an 8valve head.

Interested in any comments and feedback.

Use the G13 head, keep the g13 intake valves and get the g16 exhaust valves installed (only a couple of hundred) good for a bit more low end grunt and does not restrict the top end revability.
The g13 head has tougher rocker gear (supposedly) than the g16.

you can buy my engine set up and rebuild it..
its a VIT bottom end with a GTI head..

opnly asking 600ish

i am going to go with just a G16 EFi

Freight to Barabados might be a killer though.... Not to mention that most engines need special preparation to avoid being shipped internationally as dangerous goods.

Steve.

why not run a g16a head, won,t ping as much and is matched for the block. if suzuki thought the 13 head would have worked don't you think they would have used it?

also the16 valve pistons are dished and flycut so will reduce the compression ratio dramatically , hence why the swift guys use them to cheaply decompress their engines for turbo

Thanks for the offer, but as Gwagensteve said, shipping to Barbados maybe a bit more than you want to try.
Also don't wish to go 16valve, as the torque kicks in at high RPM as compared to the 8 valve head.

Isn't the G16A head for carburated engines? I eventually want to go EFI 8valve, but til the money comes in to buy the correct head (G16B head I assume) I was trying to save money by using what I have already available.

Yeah I noticed that as well. Will have to get the 8 valve pistons.

if your going to go efi remember the efi block has different internals, much better crank.

Tired so i am keeping this short and sweet.

Two engines + their peak torque

8v g13ba 101nm @3500rpm
16v g13bb 110 @4500rpm

I bet if you put them both on the same dyno they would both develop 101nm @ 3500rpm its just that the 16v keeps climbing due to its superior breathing and fuel mixture (multipoint instead of singlepoint injection)

The same is probably true for the 1.6l 8v---->16v

the 16 valves also have a fully counterweighted crank.

Does anyone know whether there is a difference in the Fuel Injector Intake System from a 1600 8valve EFI Geo Tracker, vs the 1600 8valve EFI Suzuki Vitara?
Would I be able to use the Tracker intake system on the vitara head?

Really? Who told you that? Have you actually seen a graph of the power and torque? The G16 16v actually has more torque at 2000rpm than the peak torque of the 8v. You might want to have rethink

For your viewing pleasure

And if you want more than that earlier then fit an adustable cam gear from occracing.com to change the cam timing.

Wow. Definately an eye opener.
Isn't that the graph for the G16A (carb) vs the G16B (Efi)
Where did you find that graph?

Farmz wrote: Isn't that the graph for the G16A (carb) vs the G16B (Efi)

It is the torque curve and the power curve for the G16B

im interest in that ajustabkle cam gear. i want to get more power form my efi G16B

that graph , something isnt quite right there ....

the g16b in the vitara only made 122 newton metres of torque at 3100 rpm , and made 74kw @5200 rpm
the g16a made 70Kw @ 5600rpm and 132Nm @ 4000rpm

looking at the graph the torque peaks at over 130 nm at 4000 rpm ?

so therefore that graph is the power and torque curve for the G16A 8 VALVE

the baleno engine on the other hand (g16b) made more torque at lower rpm than the g16a and g16b vitara engines and still had as much power as the g16b vitara (73.8 kw baleno , 74 kw vitara)

Your figures are off for the G16A 8v. It only made 55kW and 112Nm. There are a number of power/torque variations across the G16 16v engines in the Vit, GV & Baleno's generally ranging from around 69kW to 72kW with 132Nm to 138Nm. The figures from the source you have quoted have been incorrectly published.

I think the big confusion is that japanese spec g16a where ALWAYS 16v(abeilt some were single point injected) and since ppl get most of their figures from the internet north american and aussie 8v owners get mixed up.

I always though the g16a was 55kw from my research but the 112nm has got me stumped, i always though it was 127nm (or there abouts)

Now here me out

A mazda B6 8v 1.6l carb (78x83.6) has 120nm peak torque 61kw (peak hp)
A toyota 4AC 8v 1.6l carb (81x77) has 115nm peak Torque 67kw (peak hp)

granted that it occurs at different revs but its the general pattern i am trying to show

All these engines are 8 valve sohc from the 80's . The toyota has the least peak torque but the highest hp, this conforms with the idea that it is big bore and short stroke, the mazda is closer a middle engine. The 8v G16 has a much longer stroke then the mazda B6, it has less hp but more torque (assuming my 127nm is right)

Ultimately i think we need to track down a sales brochure and post it up. (even if its TBI the torque wouldn't be THAT different ) both my 8v sidekick and vitara FSM manual omit any of those figures which is not unusual since every OEM suzuki manual i have from newer engines don't have it either its the sort of information that really is irrelavent in servicing a vehicle

I mistyped It should be 122Nm for the 55kW 8v carby. The TBI 8v is 127Nm and was 59kW.

lol

dumb question time
can someone tell me the difference in
G13A
G13B
G13BA....?

also would a gasket kit for a G13A suit a BA?

thanks

i'm pretty sure the gasket are kit for A and BA are interchangeble.
B engines generally in australia refer to DOHC GTI engines (but can be 16v SOHC as well!)

single overhead cam 16 valve 1.3 litres were g13bb.

the thing is that the early ones in japan didn't have the second B just as the japan g16a where never 8v

thats funny....i've imported 2 vitara 1.6 g16a 8 valve single point injected half cuts from japan.

i can accept that, but i will ask you to accept that i have seen a g13b 16v sohc in a swift sedan
