Ah ok, maybe getting all the bits from an EFI motor would work.Peter Connan wrote: ↑07 Apr 2023 05:02 I don't think that is possible.
It would be easier and better (though probably not cheaper) to create a crank position sensor setup in the bell housing using index marks on the flywheel.
The EFI TB42's use a CAS on the Dizzy I believe.
Agreed with the GQ overall look, it just works for me, a proper looking 4x4 through and through!mvcoller wrote: ↑07 Apr 2023 11:06I have had both types, a 1995 GQ and I currently own two GU Y61s.symmetry4wd wrote: ↑06 Apr 2023 14:49 Nothing against GU owners or their cars, and I hope this is taken offensively,
I just think the square, muscular, bulging arches, and lines of a GQ are just perfect for me, I also like a more simple or "basic" vehicle. The GU is much more generic SUV/Wagon/4x4 in my opinion, at least unmodified.
All just my opinion.
With that in mind, i'm still interested if anyone has any ideas on fuel injecting a TB42 Carb.
How many guys on the forum with a TB42 EFI, only ever heard of a handful in the country?
I really love the shape of the GQ, that square rugged look really makes it look what I think a real 4x4 shape should be (nearly like the old Nissan X-Trail macho square look vs the Jelly Bean lookalike new shape X-Trail).
A GQ with 10J rims and at least 33" tyres and a 3 inch lift is a stunner and looks wise, it is hard to beat, in my book at least!! (See pictures of mine). Mine could really intimidate Taxis and windgat youngsters in their pocket rockets, particularly after I fitted the Lexus V8 motor.
My biggest gripe with the GQ is the dash, console and middle row of seats.
I just don't like the whole dash-console setup. Its layout is yugh!!, and there is not much one can do to make it better. The window switches are all wrong there, as are the radio and tape-deck positions; low down it is hard to reach if you're belted into your seat and you have to take your eyes totally off the road for 5 to 10 seconds to see what you are doing, selecting a station.
The door cards of the GQ is also a total non-event, and the front ones is as much worth as tits on a tiger......
I also prefer a double din radio, my GQ had a radio and separate tape deck, a very messy layout. I much prefer the position of the GU/Y61 radio position higher up, you hardly have to take your eyes off the road to see what is happening on the dial. On the Series 4 Y61 the radio is already a double din, and on the earlier ones, it is easy to modify the dash to take one.
The middle row of seats are a real problem, you sit far too low, either the seat is too low or the floor is too high. I made 40mm spacers the lift the seats, but it was a mission to lift the clips that hold the seat in the normal seating position. The 40mm lift was still fairly uncomfortable for my two 6ft 3 in tall sons, as their heads were only about 10mm from the roof lining.
Not many people leave rear-most seats in the Patrols, I have them out in GU 3.0 GL (came without them) and left them in the GQ 4.5 GRX. I like the way the 6th and 7th seat bench folded forward in the GQ, the seats in my two GYs fold up to the side the same as the Fortuner does. It wastes too much space when folded. up.
I also prefer the total rugged strong looking front bumper replacements you get for the GUs, I have never seen a decent looking comparable replacement bumper on the GQs, they all look like a normal front bumper with cow-catching hoops.
As far as the TB42i is concerned, my Patrol had factory injection (it was a grey import from the UK with a MPH speedo, which was a problem). I do not know if it improved matters, apart from being reliable and working properly on steep inclines where a carb may have its chambers running dry. It was not at all light on fuel, on a Namib trip I got an average 2.23km per lt on the section from Solitaire through the Namib Spergebiet to Walvis. I was lucky to get 6km/lt on the open road. This despite me doing a MAUS conversion, including a chip to try and improving consumption.
Eventually I fitted a 149lt main tank from Northern Off Road and a 60lt secondary tank of my own design built by Uys van Rooyen of Stofpad 4x4. In total I could put 210lt of fuel in the system, which in 2011/12 cost me over R2500 to fill!!! This gave me a decent range between fill-ups....
Especially with some lift and some 33 or bigger tires!
The GQ interior is pretty simple, but in a way I like, I will say that the radio position isn't clever at all. I have an aftermarket double din (not touch screen as that just wouldn't be useful in the low down position and probably cause an accident), the only buttons I need to access are volume and skip track, so it works for me and I don't need to take my eyes off the road.
Other than that, I am very happy on the inside of my GQ, could be more, could be better, but not a bother to me.
Rear leg room is not the greatest for such a big car, has anyone ever moved the rear seats backwards? I bought mine with the 3rd row already removed.
There are a lot of those very rudimentary, "agricultural" looking front bumpers/bars for the GQ, but I have seen some nice ones, and will be designing and making my own sometime later this year, so will get it exactly how I want.
There's a lot of mixed reviews on the TB42 carb vs EFI, it's interesting to hear your experience.
I wouldn't be doing it for economy, I think i've come to terms with the fact that any TB won't be economical, just enjoy it. I would just be doing it to allow for a turbo, and to have better control in certain off-road situations, like mentioned on steep inclines.
My carb sounds like its getting similar economy to what you mentioned, though I would like to get it tuned by a guru and see if there is more power, smoothness and economy to be had. Your GQ looks fantastic by the way!
(it was set up by me who knows near to nothing about carbs).The more I am digging, the more a TB45 EFI conversion my suit me better...
we will see though, I think it will come down to cost, it may end up being too expensive to convert to EFI.
I love my TB42 though, and would like to figure out something that works for me, my wallet and the engine.
Any idea's anyone what a TB45 conversion would set me back if I did all the mechanical and fab work myself, and just got someone to do the wiring???
