out with the EFI in with the carby

[RockyV]

Just something I have been pondering for 86 Rangie

just finding it hard to locate the parts, I already have a 650 Holley ready to chuck on, just need the rest

what do you guys think?

[gibpeewee]

haven`t tried a holley on a v8 but a standard v8 carby has about 130hp and the efi has about 160hp.on my carby v8s iv`e allways prefered su carbys, they allways seemed to run better than the strombergs.
one of my rangies i converted from carbs to efi and it was a huge improvement, but as i said i`ve never tried a holley

[RockyV]

I just found everything I need for under $500 including new low pressure fuel pump

I think I will go for it, no more ecu's to get wet, as for power I am sure it will be enough for me

I am going to attempt this conversion myself...should be fun

[gibpeewee]

tell us how it works out

on the rangy i converted to efi i mounted the ecu under the passenger dashboard to keep it out of the water but that car didnt have aircon so i had room to do it.

A 650 Holley is a tad large don't ya think

Holleys suck on hills, even with extended vents

Fix the EFI

X2, a bit more exxy but less headaches later. Holleys are a 4WD nightmare, I know I had one a while back :confused: :confused:

Strombergs are the only thing to fit to a Rangie regards to carbies. I just can't see why people hate 'em :(

thanks for the info guys, Looks like the manifold I had to fit the holley wont work, So I sourced a std manifold with strombergs

I just had the 650 sitting here, it was off my mates XY GT...it was too small for him

The carby won't work anywhere near so well on side slopes or steep slopes, either up or down, leaving you coughing and spluttering or even stalling out instead of driving like you can with the EFI! There is a reason that there are fewer carby comp vehicles out there, the EFI works better and on all sorts of angles! Fix it and enjoy it!

Cheers!

Peter, I love the EFI, its everything that comes with it which is letting me down. everything on my rangie that is electronic is either dead or about to die. I want to get reliability and fixabilty in the bush out of it

And if I was to fix the EFI, I have would have to spend tonnes more time and money, I have an EMS chip/computer installed which is causing most of the grief, I have started removing it all the way back to the ignition module. But even after I do that I still have to deal with std computer and set that up again. Once more I can find auto elec up here that will touch it.

my old navara 2.4 never seemed to be bothered by steep slopes, how steep are we talking? also alot of GQ's I go with are carbys and they never seem to be flustered.

Is it a V8 thing?

Shame you didn't post this a few weeks ago, I just offloaded EFI from an 86 for 2 slabs

Some carbies are fine for the bush.....just not holleys with external fuel bowls

[tpj77]

Only carbs that Rangies should have are strommies ful stop. I've owned 4 carby Range Rovers (and have one still) and never had any issues with the strommies.

At the end of the day it's a matter of economics and if you have the $$$ to spend on upgrading the EFI then it's a better option. Sometimes the vehicles simply isn't worth spending big bucks on a cheaper and easier alternative will do the job nearly as well.

I say if the efi is causing grief and is too expensive to fix then chuck it. I did just that with my 89 Rangie. the efi was a pain and would rarely run properly. The "experts" could not get it right and I was never in the RACV until I owned an efi rangie. The free towing was usefull on many occasions.
I fitted an edelbrock manifold and a quadrajet carby and have never looked back. The vehicle has more power, better economy and is dead reliable. The quadrajet works on all angles you are able to drive on without the car falling over. There is plenty of room around the engine with no pipes, hoses and wires running everywhere.
It is an easy days work to remove the efi and fit the carby and manifold.

[tpj77]

With the Quadrajet, did you have any issues with the off-road angles etc.. I know Holleys are a dead set PIA off-road, just out of interest.

My EFI is fine ATM, starts rich as buggary when cold or it has sat for about 3-4 weeks (my Rangie isn't a daily driver) but otherwise it's okay. Gives a few issues at times (surges,m stalls for no reason) but every time I go to find out what's going on it seems to dissapear funnily enough.

The quadrajet has never caused a moments problem. The vehicle is used in the Vic high country mainly so the terrain it is used on is as steep as anywhere else in the country.
Many years ago I had a Chev powered FJ40 with a quadrajet and it was equally as good on angles.

hey guys.jd loe to know what quad model and what e manifold[be nice to have in instead of being in constant fear and having lucus nigtares :]

The edelbrock manifold is specific for a Rover engine. I just bought mine from a local parts shop that had one in stock. The quadrajet was bought from Rangie Spares (LRA) many years ago as I was going to fit it to a 5 litre P76 motor but never got around to it. dont know the model but one off a 4.2 litre Holden V8 should be ok. Some jetting may be needed.If you are serious about the change over there are a few little mods and parts you need which will make the job easier if I can remember them all, it was a while ago that I did mine. I have a few pics as others have asked about the conversion so pm me if you want some sent to you.

Otherwise, look here for some info on using a Weber/Edelbrock carb.

one useful thing about holleys is that on their website they have the formula for calculating the correct size carby for your motor, as stated above 650cfm is way to big for a rangie motor...unless its running something like an 11000rpm rev limit

a stock carby off a 253 should be about the right size, most factory cars run pretty conservative tuning

depending on your rev limit (i assumed 6000rpm) a 370cfm carby would be about as big as you would want to go, so a 350cfm would be a good fit

formula for anyone who is interested

capacity in ci x maximum RPM / 3456

3.5L rangie motor is approx 214ci, 3.9L motor approx 238ci
