I'm sure this is a noob question even though I can't find anything with the search. Whats the difference between the two engines? Do they share the same bolt pattern or is an adapter required? How hard is the swap into a sierra?

Cheers

Jimny G13BB is a bolt in to Sierra gearbox and engine mounts.
Sump needs to be changed.


BB is 16V EFI.
A is 8V carby.

BB being EFI will need loom and ECM from donor car.
Superduki had one in his red tintop.
I don't know why there aren't more Sierra's with Jimny G series motors in them.

Thanks Jase, I can get a jimny pretty cheap up here so i was thinking of swapping it over and putting the power steering in. Is it the same gearbox internally or is one stronger than the other?

[want33s]

As far as I know Jimny and Sierra box use same internals with a different case and shift setup.

[sprungupcruiser]

Beautiful, thanks Jase. Is there much of a market for Jimny parts?

[Gwagensteve]

Only the bits you'd want - motor, power steer.

Unbroken front CV's for Jimny's are priceless

For the average daily driven/weekend wheeler it makes a lot of sense. If I wasnt going auto I'd definitely do it if I could easily get a hold of a motor/loom.

Are they coil pack like the some of the balenos?

can feel an idea brewing.....

Do it

[Shansh]

in all seriousness, whats the pros and cons?

obvious pro is 16v & EFI............

[SierraDan]

No adaptor. EFI, 16v
With that wreck, jimny power steering.

[Shansh]

cons other than not same power as a 1.6? it sounds like a good way to get EFI, etc without having to get engineer cert, etc for a G16B

[SierraDan]

I'd imagine it'd still need approval.

[whincup]

how would the jimny engines handle light boost (5-7psi)? internals i mean, ignore the computer side of it

[SierraDan]

Someone on here has a boosted jimny. Not sure if it was G series or M series but.

[want33s]

I doubt the G13BB would handle boost any better than a G13A or B or G16A or B.
It is a just a G13 block with a G16B head.
Suzuki engines were just never meant to be boosted.
(Yeah yeah except F6A).

[Brenno]

I boosted mine 5psi, and disregarding the computer side of things the internals were up to the task, then I sold
It to superduki who drove it to qld and sa. You don't need to change the sump over when fitting a g13bb to a sierra.

[sprungupcruiser]

I had a look at the jimny this morning. It didn't have power steering so it really defeated half the purpose of doing the conversion and it had 260k on the clock, not 200k like she told me. Shame.

[zooky08]

What year model you looking at. Don't forget not all Jimnys are g series engine.

[Shansh]

how much difference is there between the g and m series?

Different everything.

Ive driven a G16B Vitara with bigger tyres almost every day for 6 years, ive been driving a G13bb Jimny with bigger tyres on it for a few days

Its just as nice an engine on the highway though its revving more in the Jimny
its tractable enough around town and traffic, for sure a lot better than an 8 valve 1.3
Its a royal pain in the ass to get going, it might be the shorter throw of the clutch but you have to give it quite a bit more revs to get it moving without it bogging and stalling

x2

And there are 2 different 'M' Series motor's as well which are M13A and M13A VVT.

if your takling about a the jimny im going to agree with you. im running 30 with stock gearing in my jimny
on the high it just drives smothely through the rev range and sit on a 110km/h with no hasle.
yea it does bog down and takes a bit to get going but once your up in the ideal revs, it runs so smooth

thanks, good to hear from someone with experience of both g16 & g13bb

[Fatzook]

I've driven quite a few combos in sierras, and here is how I rank them in order of best to worst, judged on overall performance/ reliability/ easy of conversion.

G16B
G16A 8v TBI
G13BA auto (16v EFI coily import )
G13BB
M13a (non-VVT) (great power upgrade for a sierra, but totally not woth the effort when the above options are available)
F10a
G13a
Holden V6.

The problem I have with the G13BB is that most times, they cost as much to buy a a G16B, have as many kms, but have 14kw less, and only a few more Nm torque than the carby 1.3. So unless you pick it up for a song, you are trading off the much needed power/torque of the G16B for the saving of a few dollars not spent on an adapter kit for the gearbox.

another informed and calm non biased reply based on experience, thanks pete

Where's the GTI?

The only GTi powered zook I have been in was a hybrid G16B/gti head jobbie, and I think its fair to say, not a good example.
