tb42 into 5 speed mq patrol petrol

[ron]

hi all

how would a tb42 go into a 5 speed mq patrol petrol 6 cylinder?

can i use my gearbox or do i need 1 from the tb42 series?

anything else that i might need to know.

thansk

ron

[Screwy]

need TB42 gearbox also.

will need to cut ur gearbox tunnel out and re make a new peice for the wider gearbox and new shifter holes.
u will need all new gearbox and engine mounts and front and and rear driveshaft modifications......

at least

thanks

i might gfive that 1 a miss and see what else is around

thanks again

hi
what sort of ciosts are involved?
what needs to be changed?

thanks

[Screwy]

there is an abundance of V8 conversion into MQ/MK patrol information in the bible.
easiest motor replacement option.

there is also a massive amount of information about this topic if u use the search option.

HI,

Have you thougt of a falcon crossflow 6cly.

xf type alloy head? cheap and pleantyfull.
a/c, pwr steer ect all there.not to heavy.
parts everywhere.

castlemain rod shop do a kit.

just an idea.

[ron]

hi
how hard would it be to adapt the falcon 6 onto the gearbox of the MQ?
what about exhaust?

sorry i do know nothing about this stuff yet

cheers

there's a gearbox that's wider than the mq tranny tunnel

i've never driven a more unergonomic pos than my mq - that tranny tunnel takes up better than half the floor!!!

[Beastmavster]

Exactly what are you looking to achieve?

The other things worth considering are later Nissan RB engines - more along the size of the L series and a very common swap in the streetcar scene.

However, you need to be aware that they will run on a more canted angle than they do in the passenger car.


L series 6s can be made to put out bulk horsepower - ask a Z workshop. L28's also came out in EFI and even turbo EFI in 280ZX's - good luck trying to find a ZX turbo though.


Even the standard 280ZX motor put more than 50% more power out than the L28 in the Patrol, and can put out quite a bit more again with appropriate mods.

They can also be taken out well beyond 3 litres too.


Since these are basically the same engine they're as easy as swaps go.


In the end though for bulk torque, other things like V8s and Falcon 4 litres (eg EB-EL falcon) are going to be a better bet.

hi
thanks all

i just email newcastle rod shop about their conversion bits and will wait ands see what they have available.
and at what cost


thanks again

GQ box... the transfer shifter is on the other side to the mq one and the top section of the box is much much taller.... so if you want to put a GQ box in and keep it sorta half high up out of the way then you need to cut a big ass hole in the top of the tunnel on the left and side for the new shifter and on the back of it for the high shift covers....



HONESTLY.... All of you guys that are sitting there thinking that you want to put Ford 6 cylenders or GQ motors in yout rigs are really wasting some MEGA MEGA dollars.....

If you put a TB42 in your patrol.... why not sell your patrol for 3 grand and buy a GQ for $4500 with coil springs nicer interior, the option of rockhoppers and a TB42....

with regards to the ford motor.... You can pick up a 5 litre Holden V8 for about $400. I think the ford motor wouldnt be much cheaper than that.

its hard to get all the bits for a ford kit, whereas a V8 kit is all on the shelf stuff. millions have been done and there is loads of advice about the conversion to be had.

if you put a bigger 6 in a patrol that has a 6 already you are not going to improve your rig a HUGE amount. A V8 will be much better, and same cost and easier because of the advice...... and honestly.... the fuel bill will not be much worse for a 5 litre Holden V8 compared to a 4.2 litre or 4 litre massive ass six cylender motor out of a car not a 4x4....
TB42s get about 4km per litre out of petrol... a V8 will not be any worse than that.

hey dude i have been lookin into a el falcon 6cyl engine for my mk cost
Quoted: engine $950.00
g-box adaptor: $1100.00
engineers cert: $ 400.00
misc: $200.00
thats just a rundown of the basics if u need new clutch on engine and such obviousley theres more to consider also this is what i was quoted and im doin the work myself and so if u have to have some 1 do the work for you theres a SH!T load money right there this is not an exact figure and you may be able to get it cheaper or perhaps dearer this is just the cost throught the people i enquired through
Cheers Bourkey

Ok - As has been said by Screwy and others - check the search function - much easier.

V8 is cheap option..... pick up adaptor kit off Ebay for about $200 and a V8 motor from wreckers/smashed car(can usually sell other parts off from wreck to offset initial cost) and make some engine mounts easy enough, exhaust can be from donated car too or a new one is pretty cheap etc.... V8 over TB42, head cracking 4.1 x-flo, RB head cracking motor (I notice a trend on engines and the heads cracking etc) or what ever.... plus - in the end there is no replacement for displacement.

Except if you're talking a 5 litre carby V8, an EL 6 cylinder falcon will sh1t all over it for power and torque.

Dunno why people underestimate these engines so much..... They put out about the same power as a wrx motor and heaps of torque.

For those who remember the early EB XR6's were EVERY bit as fast as EFI XR8's, and even a little bit extra. And that means they were significantly faster than the Holden VP an VR SS as well, by about 0.7 of a second over the quarter

By the way, that also meant that they sh1t all over the famed Monaro 350 GTS as well, by the way. And the SLR5000 torana. And even the Production version of the famous A9X.*

So much for the Holden lovers. Until the Gen 3 came here, only the limited production Group 3 and Group A SS's could beat an EB XR6, and a couple of the HSV's. All limited numbers builds.

Ooops. Go back and get your quarter mile times boys.



If you pay $400 for a 5 litre v8 (believable for a flogged out 253 maybe, but not any 308 in good nick). Unless you win the lottery, it'll be completely rooted for that price, so factor in a rebuild. And a few more hundred each to get a decent carby, extractors, radiator and thermo fans, etc etc.

If you think you'll get it done, even doing all the labour yourself, for under $3k you have no chance.

And then factor in another 3k for the LPG that you'll probably need for an old v8 thats earlier than your Patrol to meet emissions compliance.



All that stuff you'll pick up easily in a crashed EF or EL at the auctions for about $1k. About $2k for an XR6 or XR8....




As for parts not being available, falcon v8 and inline 6 transplant kits can be bought off the shelf just as easily, although a little less likely to score one on ebay..





* Cant find a genuine figure on the L34 LH SLR 5000, but doubt its noticably different form the A9X anyway.

i personally bought a 5 litre out of a VC commodore for $300 and it is in good nick. i have put new exaust, LPG and everything on the car personally myself and put all that in a MQ that had a L28 motor and the entire car with 12 months rego now on it ( was unreg when i bought it ) , including the purchase price of the car stock as. owes me $2700.

dont tell me what can and cant be done when you know how to do things yourself.

[rockrover]

got quoted today 2200 for a 5.0L commo v8 with computer loom alt dizzy the lot and 900 for a 8 pot carby out of a tunna factor in bout 300-600 for adaptor and shite lookin at bout 3-5k

Thanks screwy - I wasn't wanting to be the one to burst his bubble on this one. If you spend time and ask questions and ring about rather than get first theing you come across there are plenty of bargains to be had. 5 litres are common as, just spend some time looking - personally I wouldn't pay $5 for a 253..... its like chalk and cheese, everytime I look on ebay there are conversions for $150 - $200 with everything included, engine mounts won't cost you much in materials - just labour, radiator can be used stock, just turn the drivers side inlet around and make up a hose spacer, exhaust - you can get one of them done pretty cheap depengin on size etc - Gas - not sure - you can buy second hand stuff as its pretty common on older V8's so second hand kit won't cost you much it would seem.... Having seen Screwy do most of it in a weekend on his own for dirt cheap I would say its the best option.

As for EB/EL conversion etc - Radiator needs mods, as do engine mounts, exhaust etc - just like V8 - adaptor kits have been scarse to be honest and then you have the wiring to do also.... Its not so much about power and torque figures (Bestmaster - not having a go at you or your figures here) but I think its a case of USABLE power and where the figs are that count..... low down torque is good.....

I can say - I have owned one or two of these patrols in my time and I would say the V8 is far more common conversion for obvious reasons, I have seen a few XF 4.1 crossflow conversions but only a couple....

Ron - go with what suits you best - only one way to learn I guess....

I thought we are talking about 4x4's here not quarter mile drag cars??



All good but - everyones opinion is valued and ervyone has their own ideas.... plus I learnt something - something to rub in holden fans faces.....

[pongo]

i've never driven a more unergonomic pos than my mq - that tranny tunnel takes up better than half the floor!!!

A series III XJ6 jag. the floor tunnel is wide and then runs on angles to the foot well. Very tight indeed . Id rather my patrol than my wifes 4runner and my jag anyday

Its not so much about power and torque figures (Bestmaster - not having a go at you or your figures here) but I think its a case of USABLE power and where the figs are that count..... low down torque is good.....

To which I can only show you the EF-EL torque figures... peak torque at 3000 rpm - 600 rpm lower than the "supposedly" grunty VR SS V8. And you wont buy a VR SS V8 engine cheap.

And as for an earlier VC-VH carby 308... well at about 121-126kw.....they're not even in the ballpark of even the standard taxi EF falcon 6.

(Plus of course, like for like the XC-XD 302's and 351's killed them for power anyway)

Chopped from elsewhere...

VR/VS SS V8:
Max power: 165 kW@4400 RPM Max torque: 385 Nm @ 3600 RPM

ED Falcon XR6
Power: 161kW at 4600rpm
Torque: 365Nm at 3650rpm

Ooohhh.. max power within 200rpm, peak torque within 50 rpm. Wrong torque and power curve for the VR SS V8 too I guess then.... if a falocn 6 has the wrong power curve....


Of course when the EF came out, the Falcon got even better for 4wd applications:

XR6 XR8
Power: 164kW at 5000rpm 170kw at 4500rpm
Torque: 366Nm at 3000rpm 398Nm at 3000rpm

Mmmmm peak torque 600 rpm *below* the EFI Holden SS V8 now...

Once again oops for holden.

That looks to me to be a lower peak torque, near identical top end power in a very broad spread. Pretty hard to see how that's a worse power curve for offroad, especially when we're realistically comparing old 120kw carby 308's not later EFI SS Commodore ones at that price point anyway.


Since I am not in either camp (owned both but Japcrap or Eurotrash are the go) I'm not blinded by one over the other....

At the moment, since the GenIII came out, the Holdens have been on top for power (although theres not much in it now with the 5.4 Falcon). But before the GenIII (which is what we're looking at for this guy's budget), Holdens were behind the eightball.


In the end, buyers choice, and yes Holden adaptor kits are a bit easier to score secondhand. But just consider there *are* other options out there than a Holden V8 and variety is the spice of life.


I've never seen anyone try and bolt a V6 Nissan 300ZX in there but I'd love to see it


My initial point was more the fact that he was looking at a few adaptor bits and thinkning that was all that is needed. There's all the issues to do with hoses, radiator fitment, rewiring etc. And of course the maintainance stuff you'd be mad not to do on any used engine while it's out (clutch plate, rear main seal etc).

If you have the time and space to collect the right bits at the right price. And you know what you're doing and have all the bits you need (like an engine crane). And you dont make any mistakes or have any setbacks. And you either wait until everything is on hand before starting, certainly it can be done cheaper than 3k, but it needs you to have luck buying things at the right price in the right condition at the right time.

As I put it - winning the lottery.

Most people run well over budget on an engine swap... keep it in mind.

Think I will stick with my old SD33 and work this motor.
