haha so clever....

Um i decided that i have put too much money into my motor to have a carby POS hanging off it, so i want my motor injected, im just wondering if a jimny injection system would fit on my G13A. Or if not what would pretty much bolt up.... Would a 1600 efi set up fit or would i need a different head on it?
sorry if these are dumb questions but im keen to learn more and to understand....

this is going in my lwb by the way....

cheers

[want33s]

Jimny is G13BB isn't it?
If it is then you could fit Jimny manifold to an 8V Vit head and bolt the lot to your G13 Sierra motor

Multi point or TBI , Cheers Paul.

[losfer]

the port shapes are different on the jimny , wont work on an 8 valve head.

[31zook]

cheers guy's

Ahh so why can't i bolt the jimny manifold straight to a sierra head as mine is fully rebuilt with a new cam valves and everything. Im happy to spend some time with a die grinder just making minor changes to the port shape....

sorry paul, i know that that is a type of injection but Im unsure of how i can use that information....

[LAY80N]

Im guessing Paul was asking what 1600 injection you wanted to know about, the single point TPI or the Multi point MPFI. The single point is very simple to bolt up. I have single point injection on my zook, and have done a few conversions before. Pretty sure its more than just a minor change in port style too, i think its square Vs round ports, but im not 100% sure.

The ports are less of an issue, I think you'll find the bolt pattern of the G13bb's 16v head is totally different to that of the g13's 8v head.

If you want a bolt on solution, as LAY8ON said, go for a TBI setup from a 1.6 8v motor. Vit guys will be able to tell you what models had them, I have NFI.

FWIW I had the 1.6 manifold and throttle body/injector assembly on my old 1.3 engine. It's definitly a bolt on job. As with all EFI installs you'll have to put a high pressure fuel system. I removed the stock mechanical fuel pump and made a flat plate to cover the hole.

I can't really help you much with the wiring as mine ran a Megasquirt ECU, but being TBI it should be heaps simpler than a 16v. There is no AFM either, they only have a MAP sensor.

Swift sedan 1.6's also had tbi. Any Tbi is rarer then the normal mpfi path. but any mpfi you need to change the head. Tbi looks like a carb. and should be fairly simple to bolt on/adapt/wire.

Wiring the factory setup is about an hour or so. Easy work if you have a wiring diagram. I run a Haltech ECU on mine. The factory 1.6l ecu will overfuel slightly on open loop, but in closed look will fuel quite nicely. Fuel system is easy to sort out as well. I did the same as Damo with the fuel pump blanking plate, i still have the autoCAD file if anyone wants to get it lazer or plasma cut (Having a plasma deck at work makes you lazy ).

autocad is ghey. Bring on NoOb CaD !

Just a heads up, there are also Swift sedans with 16v heads, and those definitely WON'T fit. Just make sure whatever you get has an 8v head and you'll be OK.

[Brett]

the xf ford have a tbi as well its a webber bolt patten.

the hardest bit is getting it set up right with the wiring and fuel maps.

[31zook]

cheers guys you have fully blown my mind with what yall know...

I like the sound of a single point TBI, can we head down that road. Layton, how much do you think that it would cost to set this up, and where would you buy this? Do you just get it off a VIT?

If you can get a complete Vit setup then go for that. That will be the simplest because everything is there already.

They are pretty rare though, so you might need to look at other options.

One way would be to get an aftermarket ECU like me and LAY8ON, and adapt a throttle body off something else to fit.

Or another alternative, I have been working on converting a 8v manifold to using 4 separate injectors. That way you replace the carb with a throttle body of your choice and away you go. You would have to sort other sensors (O2, IAT, water temp) but that's no biggie.

[Brett]

the tbi is the easy part, getting a ecu and setting it up is what costs the most if you can't do it (i know i cant) yourself.

what did it costy you damo and lay8on to set up?

[MART]

The best way to get a TBI setup is to pull it off the car yourself making notes , diagrams and labelling the cabling , also as you remove components plug them back into the loom , anything on the engine wiring harness is required so that the check light doesn't show faults. So choose the TBI setup you want , 90 model swift sedans have a TBI setup which cost me $300 as I removed it myself , ECU"s for this model go for about 60 dollars if you release the blue smoke , ie , cook it , yojust make a adator to suit your standard manifold out of a chunk of alluminium , Cheers Paul.

if you're doing it from scratch you're probably best off just getting a EFI motor.

[31zook]

OK so from what i gather, the single point TBI setup requires finding a swift or vit, pulling the loom out of it including the ECU, making up an adapter plate to bolt onto the original manifold carby holes, then morph the wiring together (i will need allot of help) and then turn the key for a injected 1.3?

Is that the jist of it?

Man i spent ages on google looking for a TBI set up in a swift and found nothing.... this info is great keep it coming

The manifold throttle body & injector assembly should all bolt straight on. Loom will be fairly straight forward. What exhaust manifold do you have? You'll need a bung in the for the O2 sensor. And a fuel system.

[31zook]

so you take the manifold also? i forgot to add that you need a electric fuel pump...

ahh, i heard that extractors are not worth it but every bit helps so i guess ill buy a set of extractors and bung the O2 in there

Im fairly confident now... cheers guys

[Brett]

good you do yours 1st then you can come do mine

[31zook]

haha sounds like a fair deal

[nick_bj40]

hey great write up guys

im looking into doing this to mine at the moment and i would like to know would it be easyer and cheaper 2 just fit a g13bb+box out of a jimmy??

and i kno it has been asked but is the swift single point just as easy as fit plug fuel and play?? is there any other hurdles i would need to look out for so i can be prepared.. or at least try 2 b

and also how much roughly would it cost 4 this swift set up?

[BlueSuzy]

g13bb, should simply bolt up to a sierra gbox.

I have never gotten quotes for bb motors.

But single point seems the most cost effective for a new rebuilt motor.

Everyone is different. i got sick of a slow stuttering carb 1.3. So i went all out for a 1.6Baleno mpfi.

Yeah get the manifold too. On my first one I drilled and tapped the stock 1.3 manifold to accept the O2 sensor. There is allowance in the casting for it, you just have to drill & tap it to M18x1.5

[31zook]

Ok sweet, so ill add picking up the inlet mainfold to my list of things to get... M18x1.5 is huge... will have to borrow one

And a 16.5mm drill bit

why not try and buy a nut from a engineering shop or fastiner supliers then weld it on might b easyer..

Those manifolds have a tendancy to crack, welding on one isn't going to do it any favours. If you have steel extractors then yes definitely weld a bung on.

Suzuki TBI is not real easy to find, however there are other small jap cars that have TBI that could be adapted
