Swapping 2F with B motor

[DIRTY ROCK STAR]

Hey there need some advice please...

Thinking about putting a B motor in to replace my 2F?
Wondering the following:
*any general tips?
*are the bellhousings the same? is it a simple engine, and starter motor swap?
* How much wiring would there be to swap over?
going from a 1974 with 2F, to a 79 with a B motor.
so the petrol tanks are in the same spot, i think they should be near identical vehicles except for motor?
* are the alternators the same?

and how does a B motor push 35s or 38s? highway speeds??

cheers in advance

Wouldn't a 2F have better figures than a B? Power and torque wise?

[DIRTY ROCK STAR]

man, im thinking fuel economy and side angle wise?

but yeah, 2F craps all over the B in those stakes i believe.

but its a B or gas for my truck.
I have half a gas kit as it is....

so just wondering how much work to do an engine swap, could possibly turbo the B??

[WICKED]

dude i have a B. it's alright with 34's, if i was you i'd do a turbo'd 3B. I want to do some thing similar in the near future.

if you can get a very cheap B work it and turbo it.

ditto...

seen 3b's around for about $700, slap a turbo on and you should have enuff grunt for 35+'s.

Good economy n stuff probably about another grand or 2 depending on which turbo option you go (junkyard or off the shelf).

[Ice]

Twon you know i got a 3b and 5 speed here dont you ?

[+dj_hansen+]

Find yourself a 13-bt dude.. by far the best of the b series engines...

AFAIK, should mate up to the gearbox....

[simo toyo]

on a similar subject. are the diff ratios the same in bj as fj? ie same diff???

[plowy]

a better option would be to jam a 14bt motor in it
if you just go a 3b you will be kickin yourself majorly for it

i replaced my tired 3b with the same motor ,i was advised on the 14bt and did not listen today id do anything to trade my 3b for a 14bt after driving my mates dual cab dyna thats had 60 series diffs n auto fitted to it and a 14bt as well the thing absolutely hauls


have you driven a 40 with a 3b if not pm me or someone with one in the truck n try it first before you do all the hard work

3b's are shit and slow. gas your 2f, it's cheaper to run than an oiler... fark, pcman and my 40's are cheaper to run than an old corrolla/civic. and pcman on straight gas has killer range with 2 tanks, and a 2f pushes 35's along alot better than a 3b will...

oh and the input shaft on a 2f gearbox is different to that from the b series of engines, so either factor in a new gearbox, or some way of converting it.

2f on gas... your pocket will luv ya... do you have any doubts about gas?

[pcman]

yep go gas you wont go back

straight gas in my 40
i run twin lpg tanks with chopped rear floor get 650kays safe range from about 130l of gas (about 65 @50cpl)

im about to get mine dyno tuned in the near future and im hoping to improve the gas consumption slightly


my 1.3l 1980 honda civic costs me more to drive than my 40 goddam petrol drinking pos


dunno about tyres with a 2f ill tell you when i get some real tyres in the near future

[shorty_f0rty]

in regards to your questions..

Hey there need some advice please...

Thinking about putting a B motor in to replace my 2F?
Wondering the following:
*any general tips?

In my opinion:
- mechanical, can run with no electrics
- its a diesel!
- can convert to vegi oil or biodiesel relatively easily
- almost indestructible
- good fuel economy

* How much wiring would there be to swap over?

well.. from what i have figured from my tinkering with my electrics you'd probly need at least the followign;
- glow timers and relays
- edic motor relay
- starter relays
- few fusable links n stuff.

and how does a B motor push 35s or 38s? highway speeds??

i struggle to maintain the speed limit (100-120kph) with the jt2's depending on the landscape.. downhill everythings good. as soon as there is a hint of a incline you loose speed..

i can still use 5th on the freeway with the 33's but only on the flats and hills with a good run up.

im hoping a turbo will make this more bareable on the hwy. cos thats the only area i find it lacking.. for overtaking n stuff at speed its dodge with a 3b. turbo-ing the 3b has a few options with fliped exhaust manifolds and aftermarket kits. oil skirt cooling, piston skirt cooling or some other funky thing makes the 3b respond pretty well to turboing.

if you can find a factory turbo you'll save yourself a bit of work...
hence all the recommendations for more power with a 13b-t or 14bt if you can find them or afford them.

i was thinking that with the 3b its probably cheaper to buy another instead of get it rebuilt if it ever comes to that. i haven't been able to kill my 3b yet except for frying some wiring and it just keeps on going. reliability has been top notch.

for offroading i love my 3b. no issues with it so far at all.. been on some nasty angles waiting for a recovery with the motor just ticking way.. torque and std gearing manage 33's ok .. you'll need better gearing for the bigger rubber for sure.

theres my 10c.. so spend it wisely!

[bj42turbo]

Ignore the petrol sniffers, go turbo'd 3B
Nothing constructive to say though

X2 Turbo 3b

Dont need no electric's to run.
Dont need no fancy glow start system (12volts and glow plugs is all you need)
Dont need no edic, just an old choke cable.

If ya dont need no space for camping gear, esky, or almost anything else then go for gas.

Do need a bit more time to get anyware on the highway, but im not in any hurry.

my 2c.

Gearbox has a different input shaft (not sure what the difference is but it dont fit!)
H/2H will bolt it, B motor need to change the box as well.

[Bighazza]

How about a 2H deisel

[joel HJ60]

12H-T For Sale on eBay for around $5000...

[matt.mcinnes]

How about a 2H deisel

Depends on budget but for me Gas the 2F and have it rebuilt to suit.
I have 70Kw at the wheels and just under 500Nm of Torque
Spins 35's up no problem on 3.556 Diff Ratios
With the 5 speed it will sit on 100kh all day long

Only reson i would go Deisel is for out back touring due to better availability and range.

[DIRTY ROCK STAR]

well cheers everyone for all the feedback...
after reading more on HP etc of a B motor that option is goooone.... shame too cos its cheap enough, if anyone wants one HnM is selling one on here cheap...

i have heard of a cheap 2H so i am goign to investigate that now...
and yeah if that flops then LPG me up... i already have a mixer, and an out of date tank, so a few more bits and im off...

cheers...
how will a 2H go in a 40??? mounts etc???bellhousing?

guy on 4wdmonthly.com.au forum did this swap (from memory)

a 2h is still sluggish
still slow
still more expensive to run
about the same HP and torque figures as a 3b.
have a lurverly habit of cracking heads... and diesel heads are $$$
edic motors (or realays?) go out to lunch with time.

i think the mounts lineup
your gearbox will 99% bolt up (unless there's a wierd year combo out there i don't know about)

really think about your options:

gas your 2f. you got a fair bit of the kit. you have the motor (and it's installed already) it's factory.. factory = less teathing problems... replacement 2f;s are cheap if you lunch it.

they run for a long long time. have reasonable torque. push bigger tires better than your diesel options.

so gas it. it'll pay itself off in a year or so.

OR...

Diesel conversion... initial outlay for motor.

fiddling around, pull a motor, put in another one, wire up glowplug relays, edic motor, run the appropriate fuel lines blah blah blah

parts are more expensive (2h head is worth more than an entire running 2f) glow plugs are more expensive than spark plugs (and for the record, i've changed 2 sets of glowplugs in the troopy, 1 set of spark plugs in the shorty. both have done similar distances). ownership cost and running cost for the 2f on petrol is heaps cheaper.

and: end up with less power that you started with. and it'll cost more to run than a 2f on petrol. so your spending money, and alot of time for what improvement?

you can run biodiesel?

well yes, if you can be fucked making it, and if you can source the sheite to do it, and if it actually works out cheaper due to the gov putting excise on the raw materials (if you crack it/ distill it for use) otherwise you have to set up a preheat system and stuff around with all that... all just to have an unroadworthy car (running on a non DOT approved fuel). do you honestly think the gov and the fuel companies will allow you to get out of paying your dues?

you can run underwater....

well i know a few 2f;s that'll run till they suck water. matt.mcinness's will

mines wet the airfilter a few times and not stopped...

greater outback touring range... < this is the only good reason for your application to run diesel.

so you can get the rest of your gas kit, a tube of silastic (for the dizzy) and call it good, and start saving money

or you can pour all that time and effort into a less powerful engine that costs more to run and maintain... or if you want similar power to what you've already got, throw a turbo on it for a few more grand.

or if you want to throw money at something, stay with what you've got, throw the money and time at the 2f, and rebuild it similar to matts... or throw a turbo on it (turbo and straight LPG rocks)..

go full electronic ignition for 200 bux and run till you swamp the motor... your still ahead of the 8 ball compared with a diesel swap... in other words, unless you do alot of outback touring, why bother going to diesel?

[DIRTY ROCK STAR]

Yeah roger that, cheap dodgy gas conversion it is...

it kinda suits my 40 i think... cheap.....dodgy....

Yeah...

CHEERS ALL!! hearing all the different opinions gave me things to think of..
and i wont be touring in the 40 so cheers guys
to ya all!

and 40 on!!!!

[Ruggers]

id go a 2h diesel engines should line up and gearbox is the same input shaft and bellhousing is the same. edics can be a bit of a problem but they can be fixed with a cable setup and turbo it will give you more power.

[DIRTY ROCK STAR]

ahhh the 2H has turned out to be non running.
i cant afford the $$ to rebuild a 2H...

shame too its a good price.

[high n mighty]

Back to buying my BJ for $300 then Twon

[4sum4]

I just sold my LPG complete for $150

[CanberraMav]

Turbo4t is selling a complete gas sut up for $400 bucks.
Go with that. Bargain at that price.

Canberra Mav, bargain ya reckon????
i have bought stuff from him before. but soem of his prices are shall i say "optimistic" but he does have the goods.
but no, i wont be paying anywhere near that much... so far i have a tank lined up, 92litre, for a case. comes with lines and brackets to fit in a 40. and i bought a mixer, $40.
so im cruising along ok so far.

4Sum4, yeah man we can talk.


Pauwolf, cheers for headsup. out of my $ but worth a stickybeak.
