1.6l G32 EFI ?

[VGJONO]

So while looking through the wiki on the Saturn engines i noticed that some saturn engines were used in 80's mirages with EFI, has anyone tried to use the efi setup on a RWD configured motor? if its possible to track one down would it be worth doing?

From what I have seen during my own research, none of the cars released into aus had the EFI 4G32. You'd have to import at least the intake+loom+ECU. The other option is a custom intake and after market ECU. After converting my GN Sigma's 4G54 from carbie to EFI, I would say it is worth it.

I doubt you're going to get one of these. Importers won't bother with them as they are a no demand item and they were never available locally. If you want to go down a similar path check out the FWD Galants with the G63B EFI engine or something like the EFI engines in L200 express vans (2 litre). Easier to source, easy to get spares for. And more kW's. If you do decide to do it, make sure you get something that has an exhaust manifold suitable for a RWD install (the L200 has this sorted out) to save you buying panadol.

If it has to be a 1.6 he could have a look at a 4G61. They come in several variations: SOHC, DOHC, EFI, MPI, N/A, Turbo,...
Maybe also easier to source parts for?

i believe they were in early to mid model lancers (aus) in a DOHC + EFI format

[geezer101]

They were the 1.8 DOHC engines (G62B) No rwd exhaust manifolds that I know of are available for it - it wll have to be a full custom thing.

[75glnt]

Oooh... Custom efi g32?? That's another upgrade I may do/get done hmmm, more electrical s... Maybe not??

ive seen many CA/CB GSR lancers with the 1600 dohc efi engine

Maybe those had the 4g61 engine?

[siggyloverWA]

yea sorry thats what i meant, i thought scorpma said the early to mid lancers had the 4g61 that you were talking about and geezer "corrected" him and said they were a 1.8

[VGJONO]

thanks for the replies guys, the only reason i ask is that i was going to do a 2.6 Efi conversion in my galant but picked up a cheap worked 1600 that is ready for a turbo, so if this engine turns out to be ok i might look into EFI and turbo options. might have to do some ringing around to import companies if i do decide that its something i want to do

[75glnt]

Keep me updated!! Please.. Lol I'm interested in it to. Maybe not turbo. I like n/a

[siggyloverWA]

Twin weber side draught throttle bodies would look awesome

[75glnt]

Hmm. That it would!

[siggyloverWA]

Might be easier to source in Australia, see weber manifolds all the time.. might not be cheaper though. Sure would look the part

[75glnt]

I'd love to have the skills and tools some of you guys have! to make a custom intake for my g32. Some say its not worth it. Go 2.6. But I love the sound of a g32. Not to mention its already in there. So no mods for engine mounts, thermostats and so on just my opinion although I'm considering 2.6 efi in my ga

[VGJONO]

Sooooo, i just picked up some motors, one of which is apparently a 4G32 out of a Cordia, That has a single point ECi or efi system, now im wondering what would i have to do to put this onto my chain drive motor for when i run a turbo ??

Sorry for the photos worthy of some bigfoot conspiracy theory




the first thing that i can see is the plumbing for the cooling system, manifold would need to be modified and a thermostat housing and what not made to fit to the front of the head instead of the rear like this is setup, maybe even i can make an adaptor to fit the ECI/EFI to a normal carby 4G32 manifold???

[geezer101]

The single injector is off a Sirius G62B single cam turbo engine. And, it is super crap. It's not going to bolt up to a Saturn engine without some heavy modifications. The single ECI caused lean outs when the boost was played with - it eventually caused the exhaust manifolds to run so hot they'd crack. But in light of my earlier comments they are a good way to cut your teeth on turbo charging basics and were really easy to trick up for a bit of extra boost.

[VGJONO]

Fair enough, what other options do i have in any form of fuel injection for a 4G32, i would be running a TD04 turbo of which ran on this injection setup prior and i would only be playing with the boost a little for the time being.

[geezer101]

I haven't had a good look at this yet but it 'might' be possible to unbolt the injector and throttle housing and fit it onto the stock Saturn manifold. It will simplify the set up a bit by not having to have the 2 manifolds cut up and modded into one...

[geezer101]

O.k. I had a look at the injector and throttle body housing and it looks like a bloody 4 barrel (big square pattern for the bolt holes). Might be able to make an adapter/spacer plate similar to the ones used for down draught Webers and have the inner plenum port through the spacer cut on an angle + remove the bridge between the primary and secondary port in the manifold. Fiddly but nowhere near as bad as trying to chop up and weld 2 different manifolds together...

[RaptorReed]

on the topic of EFI, has no one installed the g32's big brother the g37?

Unless that isn't a common motor over there of course?

[VGJONO]

Have a 4G37 fitted in my new Wagon, just with a carby though, not the EFI one.

[RaptorReed]

How does she run?

[VGJONO]

Havent driven it yet but seems to run pretty good also it isnt a common motor to find i dont beleive, pretty sure this one was converted from east-west configuration and was in a Hyaundai when they found it

EDIT: just realised the link i left on here messed up and linked people to a picture

Must've been out of an X1 Excel as they were the only Hyundais that ran a complete Mitsubishi drivetrain

[Scorpma82]

Look for a Hundai S Coupe from the very early 90's....they ran a 4G32.....any they might be an EFI setup too

[75glnt]

X3 excel had a 4g15, same as a lancer... Wonder what they're like for interchangeability?

[geezer101]

The manifolds are on opposite sides of the engine compared to standard so this will cause you the first head ache. And if you're using the single cam engine, the inlet manifold is really tall so I reckon it will have clearance issues and will need the Magna mod treatment of cut and shut. Then there's the coil packs on the back of the head (they should be easy enough to mount on the side of the engine bay somewhere) but the coolant hoses will be a killer...
It's a shame they are such hard work (if at all possible) to set up for RWD as they are an affordable engine to get a hold of.

[Scorpma82]

Its looking like ur going to have to stick to carbies i think mate
