| Post subject: | g13b single point injection on a g16a? |
Hi all. I'm new to the forum. But have seen some cool stuff/helpful stuff on here I'm after some advice/help. I have a 94 jimny sierra with original 36000 km on her:) (x japan) which had a 1.3 single point injection motor in her, and I want to see if I can put the single point injection on to a g16a carbed motor from a vitara and put the 1.6 in the jimny. I still have the imu and wiring loom on the jimny. Is it possible? Any help would be great:) Many thanks josh |

A) Probably swapping the manifold will work, but you'll also have to swap the distributor, assuming the cam drive is compatible and determine if there are any other sensors etc that also need to swap. B) swapping the cylinder heads would probably work assuming the cam sprockets have the same tooth profile (this is not guaranteed) C) It probably won't run that great, but at least it shouldn't do all the carby things that make carbies suck. In my opinion the tuning on early 90's JDM suzuki stuff was pretty coarse, you might get away with it. I'd probably tun a wideband 02 sensor on it to see what the fuelling looks like and short of retuning it, you might be able to fiddle with fuel pressure a little to trim the mixture. G16A Escudo's (Japan) and Sidekick/ Geo trackers (US) were sold with single point injection. |

OK thanks for the info:) I think I may go towards maybe doing a SU carb setup on the g16a, can you or someoun else tell me anything o that setup (or should I start another thread?) Thanks again:) |

I don’t think I’ve ever heard of anyone running an SU on a Suzuki motor. Interesting, but it’s not 1988 and the advantages of EFI are well known. Odds are the time and money involved in getting an SU to work will exceed getting the efi system to work properly. |

A mate of mine had an SU HS6 on his Sierra, it never worked all that well but it wasn't set up properly. We replaced it with a 4K carby. The SU had a simple adapter, just a 90° exhaust tube with a flange welded to each end. |

Yer that's what I'm thinking of doing (but just making the adapter out of stainless) I like the idea of a car. 1 cos I don't have the donned 1.3 efi motor. and 2 cos I like the simplicity of a carb:) Can anyone help with ideas on carb setups that run good and are simple on the g16a? And readily available parts wise (I'm in NZ if that helps for yous to get a idea on part availability) Thanks lots |

I'm just whingeing up carb options. I don't actually have efi of the doner motor, so I would have to buy one. which in of itself is a bit of work, not even getting into seting it up:) For the 4x4ing/driving I do, I don't really need efi. If any of yous can help me to figure out a good simple reliable carb setup that I can make work with the 1.6 I'm in nz so not 100% sure what carbs I can get that will work on the 1.6 Any help will be great:) Thanks heaps. josh |

If you want to go down the carb route, Just get a stock mikuni G16A carb and set the car up exactly as per a carby G16A. Then you can use the factory service manual to confirm setup and operation instead of being on your own. When you have an issue you can follow the troubleshooting guide to check whichever system/circuit is faulty and step through repair. I don't understand what "needing" EFI means. EFI cars start and run consistently and reliably in all conditions and if there is a problem it will typically diagnose it for you itself. I mean, I guess not everyone needs that but it's pretty convenient. EFI is far simpler to diagnose and repair than a carb. You already have the hard work done, the car is wired for EFI and has an EFI fuel system. You can pull all that out and put a carb in and then deal with all the "theres something wrong with my carb" and "can anyone tell me which carb rebuild kit to buy" and "I got a bad batch of fuel and now my car won't idle" etc. My ~260K old 1991 G16B is smoky, most likely has a cracked head, and has never been opened. I change the oil about once a year and recently did plugs, cap and leads because they'd got too old. It starts every hit of the key. I've put fuel in it that was so stale it wouldn't run my lawnmower. It didn't care. I can unplug all the sensors and it still starts. (and then it tells me which sensors I've unplugged) I can follow troubleshooting charts for everything if needed but I don't need to because it all works*. Every sensor is from 1991. I like it because I don't want to be messing with a carby, I'd rather be working on other things to make my car work better. I'm the first person to admit I'm prejudiced against the G16A. In my opinion they're lacklustre and marginally reliable and by now they're also rare and worn out. I even bought a "reconditioned" G16A back in the day (at which point it couldn't have been more than 6-7 years old, which tells you how durable they are) and when it was installed in a car it lasted months before it ate itself. *yes, some of you may know I had a long run where I couldn't get my car to start properly. Which was the dead leads/plugs/cap, and the hall effect sensor too far from the distrubutor shaft. Nothing to do with the EFI system - these are all faults which could befall a carby car with electronic ignition, like a G16A. |
