TB42 vs TB42E

[jhetland]

Hi All,

Im considering buying a SWB GQ/Mav, and had a look at a 88 Mav today. Looked very neat, but diff lock got stuck in the on position, so took it back to the dealer. I noted that it was a carby, and was wondering what that meant in terms of $$$.

I got these figures out of 4WDMonthly:

TB42 4169cc petrol, carb 125kW@4200rpm, 323Nm@2800rpm
TB42E 4169cc petrol, EFI 129kW@4000rpm, 330Nm@3200rpm

I dont realy understant what that means in terms of efficiency...

Is there much difference in the fuel economy running petrol on these two? Not too keen on lpg. I want to put my 33" on as well, will that make a significant difference? And finally, how big is the stock fuel tank?

Thanks,

Jo (Going from Toyota HJ47 troopy to a SQB GQ/MAV)

That can happen, rolling back a few feet can release them.

EFI should be better depending on what you want to do with it.

EFI will be better petrol gets 20/100 or worse... 95ltr stock tank.. 33's will make it worse on economy

I bought a carby because it's easier to fix in the bush. Can be a PITA to get running right.

[jhetland]

Wow! 2 minutes and replies allready!

It will mainly be used for the bimonthly long highway trips, weekly shopping, and the bimonthly camping/4wd trip. It wont be a daily driver, or used for hard core 4WD stuff. But with the fuel prices going up, Id try and go for the better option. Id buy the TD42, if I could find it, but not sure if its worth it with the higher price.

work it out

14/100 diesel
v
20/100 petrol

[blkmav]

In that case go EFI

gqmad has a diesel shorty for sale

Iv had a look at all the adds, but I have been instructed that body or suspension llifts are no go. Bit suspect of buying a lifted one to lower it.

20/100 petrol

Im not in a rush to buy, still searching. 20l/100km goes for both TB42 and TB42E?

Thanks for the help!

why no lift ??? find one with 2 " spring lift as one that hasnt been lifted being that old will have shagged springs anyhow

save ya buying new ones after ya find a car

Well, the misses doesnt want anything lifted, as she is concerned it will roll when she drives it, and im sick of not beeing able to fit in multistories, If it makes the car higher than 1.8m, im sceptical. The Mav I had a look at today, looked like stock suspension, and I could only just see over the roof. Must be 1.75m tall?! Apreciating the advice and thoughts guys!

I have an EFI GQ. It is very smooth. I dont have to worry about setting jets on carbies etc. Easy.

Fuel consumption probably isnt that different between the two.

I figure 99% of cars went EFI for a reason

[turps]

Most car parks are 2.1m high. My SWB GQ has 50mm bodylift, 10-40mm susp lift and 35" tyres and it goes into alll the carparks I have found.
And as much as I dont like it, it leans over a long way when pushed and it hasnt fallen other yet. A lift GQ will be more stable than the old cruiser.

[awill4x4]

I'm pretty sure none of the shorties came out with efi anyway, I think all the petrol ones were carby.

Why would you lower it? 2in lift is perfect for general duties.

I must admit, every GQ I know of with a 2-3-4in lift rolls onto roof every time they go out of the driveway... maybe she should look at a few photos of the side angles a GQ can get to that are safe as houses.. if she can find a road thats 1/10th that side angle then post up the subject here, it would require a road trip.

jhetland any coil sprung truck will feel super weird to drive for the first couple of days
mine has a 2'' spring lift and 32's and is still stable as on and off road with the swaybars on

i felt uncomfortable for a week in the GQ LWB after getting outta a 85 dualcab lux with h/duty 2'' leafs.

the GQ felt like it was all over the road for the first week but after having it for 2 yrs now i'll never go back to leaf sprung 4 x 4 's

the coils are just to comfy

u should take a few for test drives with 2'' spring lift with the other half as u she may be suprised how steady they are on road
check out the link at the bottom of bogged's post unsure of his lift but u can see how level the cab is off road
hope this helps

True, but I've never had to set carby jets in any of the cars I've owned except when I've increased the motor size or other mods. If he can find a diesel great, but then may want to spend another $2k on a turbo.

I just used 80l to do 400km mostly freeway and hard sand use with some 2wd soft sand playtime included. The EFI would have to be a bit better I imagine.

And you also have to remember diesel is more expensive than petrol in some places. I doesn't sound like he is doing high milage so the fuel cost difference probably won't bother him, he can always convert it to diesel later. I only do 6000km a year so don't really worry about fuel cost.

They must have serious driveways, road trip?

Shortys did come with EFI have have seen a couple. They do seem to be the later models though. And at least 12mths after the LWB's get EFI.

[gq4200]

I have both Carby and EFI, and the EFI uses 25% less than the carby. Carby 20L/100km EFI 15L/100km (at best), oh and both Auto also.

EFI always runs nicer than the carby, but expect to do EFI pump and Injectors at this age.

Go the EFI!

[Beastmavster]

My shorty has 2" dobinson spring lift and is about 175cm high on 33" muddies (285/75/16"). A little taller than a normal 33x12.5x15" and less sidewall so better onroad.

It's a close fit in a couple of carparks marked 1.8m but ok even with the sunroof open.

I fitted the softest springs I could get for flex and it's still pretty good to drive with no swaybars on. Having the front refitted with disconnects did make an improvement though.... a lot of guys dont care about that since they're the only ones who drive their truck but in my mind it's worth it.

I think with medium rate springs instead of the softest you can get she'll have no problems. I was punting on wet roads around the hills this morning doing 90kph on those advisory 60kph signposted corners so it can't handle too bad.

Of course... in the sedan I probably would have felt comfortable at 100 instead (speed limit 100)

I've had EFI and carby. EFI was a bit better on fuel, but not enough to warrant the extra dollars. Just remember the EFI is big bucks to fix if you have dramas. Carby is simple and its dirt cheap to get another carby if you do have problems. The extended rotor and extractors/bigger exhaust made a huge difference to the power and fuel consumption in my carby shortie.

Tyre (brand and size) and running swaybars are as important as the the lift, for good on road driving. Anything over 2 inch lift, and the mrs will really notice the difference on road, even with sway bars. My mrs won't even drive mine to the shops now its been lifted, but its alot higher than 2 inchs.

So what sort of economy are you seeing now? And what did you pay for these mods?

Thanks,

i have a gq ute with carby petrol, it came with carby which annoyed me heaps as i want to put my turbo on it, so i went out and bought fuel injection for it big $$$ it has 5 inch lift 2 inch in the body 36 simexs running soft rate spring all round so smooth in the bush i put up with alittle lean on the road for that, of course i dont run sway bars this is the 3rd patrol i have had and this one is the second ute all have been 4 inchs and taller all with body lifts my wagon ran a heavire spring rate then this ute but still soft it had no sway or lean over at all and my wife loved it she said it was great to see over all the traffic that was in front of her, and the fact that she was so much bigger then everyone else, of course she new it was big so didnt bother with under ground car parks she just parker out side no big deal, she did park underground once no trouble so you can go big but just keep in mind the poundage rate of your coils. all that and i cant remember my point to all of it..

Interested too - never heard about this extended rotor stuff.... but already have the extractors and she still way thirsty....

[tuff dog]

G'day Jo

If you got the cash go for a EFI over a carby. You will get a little better fuel economy but above all go for one with low kms.
Now don't let the misses hold you back. I have 4" spring lift in my GQ ute with 35" tyres no sway bars and I can't roll it on the road.(touch wood)
I suggest buy the misses a Nissan Pulsar and you buy the shorty and go NUTS!
