[Trypt]

I'm doing some future planning for when Bruno goes bang.
Now I can't really go without my car for anymore then a week.

I was thinking of doing a g16 Carb conversion to cut down on costs, don't really need loads of power and cbf with FI

Now I was just had a brainwave. What if a buy a second g13 and put a g16 head on it??
Will this have any performance gain?
My thinking is I can buy and rebuild the second engine over a month or so then just swap em one weekend.
And I won't have to worry about engineering?

Opionions, thoughts and ideas would be greatly appreciated

g13b is gti btw thats twin cam efi

Did I miss something, what has that got to do with what he just asked??

And isn't a coily engine a G13B (G13Ba) which is a single cam 8 valve

[Trypt]

sorry i always thought it was a 13b. my bad its 13ba.

[KEENSY85]

I don't think it will much difference there might be for flow thou I'm not sure how diffrent the g16a head is I havnt had experience with the 1.6 head ,I do know the g13 head has some hidden power in it if u put the work and shave the head and port and polish it also there some dead spots within the head wich if u fill or weld (were the valve guide s run through ) and reshape could possible realy help ,the g13ba is a non interference engine so u can actually in theory shave a lot off the head but only if the bottom end can with stand the extra comp. Who knows about the g16 head are they better in many ways.

[2stroker]

You will spend a lot of money trying to get a 1300 head to flow anywhere near as well as a 1600 head. Unless you really know what you are doing (read performance cylinder head specialist) don't waste your time wrecking a head.

Where did you get that idea from?

What makes an engine a G13B - the engine number prefix?

What would you say if I told you I have two 1.3 engines here, both have G13B engine number prefixes - one IS a 16V DOHC EFI from a '90 Swift GTi, the other is an 8V SOHC carburetted in a 93 5 door Swift hatch, yes, it is the original engine, yes, I've owned it from new?

What would you say if I told you I've seen a Swift GTi where the engine number started with a G13K prefix?

That was my thinking exactly. Id rather not mess around too much with a head.
Maybe just a port and polish of a 1600 head.

Will a 1300 block with a 1600 head be more efficient?

Err because he is right?

They may use the same block, but the general term for a Gti motor is g13b, g13bb for jimny(early models), g13a for nt and g13ba for wt and g13collapse.at.90k for coilies.

Generalization isn't necessarily 100% right. All sorts of oddball stuff has come out of the Suzuki factory.

[Brenno]

That is true JrZook, but the reason I am making the connection is because in his original post and topic heading he mentions G13B vs G16a, which most guys on here would think as GTI, therefore he isnt going to get correct answers until someone points it out, as Jonno has done. My CA has L18 stamped on the engine block.

[2stroker]

The confusion comes from the heading which does say G13B V G16A and you are right in saying that when someone says G13B people usually think twin cam GTI, but when you read what he says in the post he is explains that he is talking about non efi engines not twin cam efi gti.

To be precise the coily single cam 8 valve 1298cc engine is a G13B, it is cast with G13B on the block, but unlike the G13B Gti Twin Cam the coily G13B has an extra letter stamped in the engine number and the letter is an "A" so it is commonly known as a G13BA.

Sounds like a good idea can u post pics of the head throughout so o can look at for my next engine build:)

[KEENSY85]

I think the block I have is a g13b and it came out of a 92 auto golden barina. And its was its original engine I may be wrong its been built since but its still only got 8 valves for know any way

Seriously mate if you don't know what you are doing don't mess with the 1600 head either, you are more likely to make it worse not better.

And yes the 1600 head, manifold and carbie will improve the 1300 but don't expect it to be better than a 1600.

[Trypt]

my plan is to buy another engine and do the work on it, so i can learn.
i dont expect a 1300 to perform better i just dont want to do a 1600 conversion as it will need engineering and that will mean i cant drive it on my p's

[2stroker]

I am not saying don't do up an engine what I am saying is there are lots of things you can do while still staying within the means of a home workshop, modifying cylinder heads is a specialist field, there are a handfull of people around the country that really know what they are doing in this field, you can read all the books you like but it takes years of experience and specialist equipment to modify cylinder heads for performance, it is done by trial and error and can cost thousands of dollars in labour to get results. I know of a fellow who spent around over $1000 on a 1300 head and in the end it flowed nearly as good as a 1600 head and that was at a place in Brisbane that specialised in cylinder heads. I am saying dont try running before you can walk, forget porting, polishing etc, bolt on a good 1600 head, mild cam, carbie and extractors and enjoy.

[KEENSY85]

Just a thought u recon it would be cheaper to do gti conversion or a 1.8 transplant

[2stroker]

what 1.8?

[KEENSY85]

Baleno motor apparently

[Trypt]

Like i said, dont want to do a transplant as that requires engineering then makes it illegal to drive on p's

Ok thanks 2stroker. i will go down that path. will 1.3 extractors fit the 1.6 or will i need to modify some

[KEENSY85]

Sorry mate I missed that

[Trypt]

I will start hunting down a second 1.3 block

Two questions for you ...

First - what makes him right?

And if you feel he is right, perhaps you (or he), would care to explain the anomalies I described - I own, and have owned from new, a Swift with an 8V SOHC, carburetted engine, with a G13B engine number prefix - you can take my word for it, this is the original engine, original head, original carburettor - if you have access to the Suzuki dealer databases, I'll provide you with the chassis number, and you can look that up, and get from the manufacturer, the engine number and the specification of the vehicle as shipped from the factory.

Second - do you really think that a g13a from an nt and a g13b from a GTi use the same engine block - or was that a slip?

[Rhinoman]

If you go for the G16A 8V head then get the cam too as it has a little more duration and lift.

To be precise, the G13A block is designed to run a 77mm stroke crank for a 1324cc displacement, while the G13B block is designed for a 75.5mm stroke giving 1298cc. The blocks are different castings to allow the 1.5mm difference in deck height and are NOT a designation of the specific type of head (8V/16V, Carb/Efi, SOHC/DOHC) fitted, although there were only certain combinations factory fitted.

You'll get no argument from me there - I will however point out that the "factory fitted" combinations may vary from one market to the next.

Brenno? jonno_racing??

the 1.8 is a different fish, Its a J motor.
