2f fj55 transplant - suggestions please!

[foodie]

Hey everyone,

I have a nice FJ55 with a not so nice guzzling 2F.

It runs perfectly and suits the car, but does not suit todays fuel prices nor does the 4spd suit todays highways.

I am after suggestions on what engine to transplant into this baby.

I have my heart set on an a lexus alloy v8(how do these run on gas?) due to the technology behind it, would be smooth and economical without a lead foot.

Please spam what you would do, but specifiy if it's what you would be dreaming about or what is actualy possible without a huge expense.

Thanks!

Dude!

Small block Chev , the most common transplant, put it on gas and you will never look back.
350 for a wagon, 5 klms to the litre on gas , bucket loads of power.

Cheers

I'd say much of the 'high tech' benefit of the 1UZ would be lost on gas. Still a good motor though.

[mule75]

if your gonna put it on gas there is no need to get a efi v8. bung a chev in it, they've been around for ever and there is a massive range of parts avail.

I have a nice FJ55

never knew there was such a thing.. the ugly duckling of cruisers..

[joeblow]

mmmmmmmmmm.....toyota alloy quad cam multivalve 6 bolt mains v8 mmmmmmmmm........oops.

[HotFourOk]

You said you want a motor to suit the car.... a newer Lexus V8 wouldn't suit it at all!!

Put an older carby 350 chev in it as GUEEY said.. lots of them on gas, and you can do mods so easily to them. It has been done so many times...

Also a great choice of boxes to go behind them.

Might be a bit easier with the "higher powers" also with the older motor

[Stackson45]

Go the chev - a good way to go about it is to buy a cruiser already V8'd - seen em on ebay for buy it now prices as low as $2000, so once you count conversion kit prices, and all the other little bits and pieces, plus you can sell the rest of the car as spares. I did my first chev2cruiser conversion buying the engine 283 chev $300, rebuild $1500, 2nd hand coversion kit $350, clutch bits $300, disc front (back then) $950, etc...

This time, bought a ute with 350 chev, pto winch, on gas, 35's for $2800, then sold panels and bits and pieces.

My 2c.

[bad_religion_au]

easiest and cheapest would be to throw the 2f on straight gas then you can tune it purely for gas...

my 2f on gas (dual fuel) is as cheap to run as my brothers corolla on petrol

[foodie]

i doubt the 2f on gas is ecconomical.

It's old technology with very bad characteristics mad to suck fuel.

I like the idea of getting another vehicle to be the donor.

I started to add up all the little bits here and there and it does add up.

chev is nice, however it's 5.7 lt and would use on gas what the 2f does on petrol currently.

308holden or 307chev would be the largest capacity I would go.

Any inline 6 options? Turbo 6 ?

[FourSpin]

i had a 2f in my forty series, purely on gas, tuned for gas, with a valve-lube setup...80lt gas tank would get me 300 - 340 km depending on how much i gave it the right foot

Not correct mate.Unless the motors very badly tuned etc.Ive had some very strong ford engines that returned pretty good fuel figures when taking it easy.(850 double pumpers carbs etc)The 350 would be working easier that a 5 liter and would return as good if not better fuel consumption figures.

Have you thought about a straight 6 out of a late model ford.Good power,light and pretty cheap.No idea on how hard to fit it up though.

My 2F on Gas is pretty good with heaps of power, but if it's economy your looking for, a 4x4 is not the answer V8, 2F or a six are all thrirsty at the end of the day.
I'd go with the 2F on stright gas. I get 4.6km pre Ltr out of mine.
Really depends on what budget you have to rebuild with?

[dibbz]

stop driving with yer stilettos on....

Every option costs more than you paid for the car, just get a 3 cyl charade and drive that to work instead

[Sixty's Guy]

How about a 13BT? Didn't the 40 series come out with the 3B? If so, I would think that it would be a fairly easy swap. And it stays all Toyota too. Roothy in 4wdmonthly did this conversion. Better power and better fuel economy.

doubt all you like, i just drive the thing every fucking day. when on gas "technology" doesn't mean that much, as the biggest step forward, economy wise, was the move to fuel injection instead of carbies.

my 2f, tuned for dual fuel (more gains to be had) gets 300-350 k's out of 75 litres of LPG. averaged over 5 years. and i don't drive like a grandpa.

as for the 13bt, you need a gearbox out of a 3b equiped cruiser, so there's another expense... radiator inlets might have to be swapped...

really... 3 grand or so for whatever swap you do is alot of fuel to use

[Sixty's Guy]

Reading the original post I think that replacing the gearbox is part of the plan.

[foodie]

piss off dibbz, least my car gets out of the garage!


ok okok, economy is 1 thing, revs and better highway cruising is another.

2f + 4spd + 4.1 gears = revving tits off at 100.

looking at 33's to replace the 31.5's I have - this should help a bit...

5spd and gas conversion, 33's would be nice!

I heard you can get a 5spd for a 2f, but am I dreaming that this would fit in a 55 without major cost?

Worked 2F + 5 Speed + 4.556 turning 35x12.5x15 AT's or 35x10.5x15 Simexes on Gas and for those that have seen it power is not an issue, breaking CV's was how ever, mmmm Chromoly 30 spline

busted link

so what 5spd have you got behind the 2f?

mines in an fj55 - are all 2f's the same?

Just tried the link works fine.
5 speed is a stock Toyota one for the 2F from a 60 serise.

[foodie]

Did you have to adjust the input shaft length?

crossmmber mods?

5spd would help massivley on the highway.

You have heated up your 2f, what's it's topend like now and what have you done to it - got a working link

www.3rdrock4x4.com seems to be down.

[FourSpin]

2F's came with 5 spd in 82+ LX FJ40's from memory...I know nothing about 55 series...as they are just hideous and don't want any of that to rub off on my retinas ....but yeah, deffinately available from LX model FJ40's

Five speed bolts stright up no problem. Would love to have a look at a late FJ40 sometime with a factory five speed in it as I know it's a real shoe horn job to get mine in. Tail shaft lengths change front and rear and there are a few minor issues with clearance but nothing huge. Also with the 5 speed you need to alter the floor pan slightly to allow the shifters to come through in a different spot. Again no huge task just a pian in the arse but that comes with all mods.

Highway flatout can touch about 130 on the flat and that's with the 4.556 diffs and 35's

As for your model I can not say, what year is it? Does it have a 4 speed without the split transfer case or the later 4 speed with split transfer case?

How much room is there around the gearbox tunnel to put a longer box in, you need around 90mm from memory. The 5 speed is the same size as the 4 speed just has the extra length and a fraction more in hight as the top of the box is different where the shifter goes in.

One of the links at the bottom will take you to my members page but as photos are off line sorry no pic's.

The link works just need to be patient you get a blank screen for a while and will need Appples quick time I think it is to run the clip.

My 2F was build to suit gas with low down torque so cam and head were changed, engine was fully re built and balanced I also run electronic ignition and cerramic coated extractors.

By no means is this a cheap sloution but a V8 or any engine change needs a engineers ticket plus a lot of work and dollers. It depends on what you want and your budget is. I,m a purist so the 2F stays.

Think of it this way an engine rebuild and 5 speed well done well cost $7,000+ unless you do it yourself (not easy) a V8 conversion no less plus all the hassle of engineering tickets. You can do it on the cheap but at what cost in the long run.

So for me if its fuel your tring to save how long will 5000+ ltr last your if you stayed as you are and spent the money on fuel?


It's great fun putting big V8's to shame with a 2F

still a consideration... 5 speeds to suit the B motor would be harder to find than petrol 5 speeds

[bad_religion_au]

a 60 series 5 speed should bolt straight up, or a 5 speed out of a late 40 series... might have to enlargen holes for shifters... they have a T case crossmember, you can mod the 60 one to suit, get a 40 series one (i think chassis width is the same between 40 and 55) or just run without one (yours is doing it now right?)

it'll be a single piece case, the 55's never came with split cases.

oh and drive shafts will need to be lengthened (front) and shortened (rear), but in a 55 won't be a problem. from my hazy memory, you don't have any chassis crossmembers or anything to get in the way of the extra length present in the 5 speed...

ooh and the drive shaft flanges will most likely be a different bolt pattern to the 4 speed ones... simple solution, get the female 1/2 from both the driveshafts that came with the 60... the d-shaft splines will match up to your existing shafts, meaning they'll still bolt up to your diffs.

and matt, i don't know what your doing wrong, my stock, H powered troopy with 31's and 4.11:1's and a 4 speed saw 160 on the flat once... to be young and stupid again

out of interest matt, is your 5 speed an ex 60 series one, or a genuine 40 series one? i've been told the shift plates on the top are different between the two, and that'd explain why yours might have been a shoehorn job.

[shorty_f0rty]

the 5spd in my 84 bj is a h55f, so maybe thats the one your should keep an eye out for. i have used a 55# 4spd front shaft for my rear and the flanges matched up fine.. so you should be cool.

got both of mine from 4x4parts.com.au, give em a call and see if they have any and get a ball park price. i guess it makes sense that there could be two diff types? of gearbox for swb and lwb and same goes for diesel vs petrol, if they have any, go in with a tape measure and check em out. i think i paid approx 60-70$/each for the shafts to help with your budgeting.

not sure but would gearbox mounts/crossmembers be an issue? i know i have one under my 5spd.. and i think i can see a one sided mount on the 4spd.

heres some crap pics from under foodies 55..
the only other issue i can forsee is the long range tank being in the way..

55 4spd

40 5spd


my 5spd crossmember/gearbox pix for ya:


55 4spd crossmember in top right corner?


55 4spd 2nd tank

1st point, yours is a h55F, same gearbox, but they have a different input shaft to make up the length difference, 4 cyl - 6 cyl, so not all h55f's would necisarrily match up to a B series engine. again, the flanges DID change, not sure what year, so if the original poster is using a 60 series box, the flanges MAY BE DIFFERENT. i know because i've tried using driveshafts off a 60 series h55f before and they haven't matched the 4 speed pattern. any h55f from a 6 cylinder (petrol or diesel) will be easy to use behind a 2f. the later ones MAY need a different clutch disk (dunno, have to measure one when we get one in at work) but they also have a lower low range (2.25:1 instead of 1.9:1)

those "crossmembers" are the bellhousing mounts, and they are the only thing supporting a 4 speed. it's the same for non-splitcase 4 speeds in 40 series...
