- The basics you need to know to put a astra electric power steering pump in your car.
Pump size 28x22x14cm
Wiring:
Big brown - ground
Big red - power (use 70 amp breaker)
Little brown - not used
Little black - ignition power, switched
Little blue - switched power, best to wire to get power just after the little black, this will turn the pump on faster. (factory off alt charge light)
High pressure bump tube to -6 fitting off pump, m16 x 1.5, Raceworks rwf-741-06ss
Use LDAS fluid in pump
Nissan rack fittings, m16 x 1.5 low pressure, m14 x1.5 high pressure
FC Rack fittings, m16 x 1.5, Raceworks rwf-741-06ss
Use PTFE line for the high pressure
Push lock rubber line for low pressure

I used Astra/Zafira pump in a CRX a decade ago, I've learned couple of things back then. If you daily your car do not connect both wires to ignition, you'll have like 10 seconds with no power steering as the pump slowly ramps up the speed. When you connect the alternator wire it jumps into action instantly. Added benefit is that it will shut down if you ever loose alternator giving you bit more reserve power. Also do not mount it on a firewall and definitely not just with a rubber washer as you'll hear the loud pump whine all the time. Other thing is not running the reservoir half empty as the pump itself is inside it and top of it would be dry. I think this is what seized my 1st pump. Not mentioned in the video, but maybe it's just obvious is that you can loosen that large clamp and rotate the reservoir to point the return line in a direction you want. also I recall I've measured less than 10 A draw at idle and up to 30-40 A peaks when turning tires at standstill. I bet it may vary from car to car.
Exactly the video we need, I wish all auto videos were this professional and informative. Cheers
Straight to the point no fluff,, Thank you!
Thanks for the vid man. About to buy one of these for my car and your video took a tonne of the guess work out.
pretty awesome ive used volvo and mr2 pumps before for similar results. love the vids just picked up an s13 your black one was quite the inspiration keep it up!
Appriciste it bro
Great video, but im having an issue where when the steering is heavy and i turn, it is a bit slow to react to turn the pressure up. I have a cooler and temps aren't hot, i have good wiring and big alternator.
I wish it was quicker to react or there was a was to keep it on higher pressure.
Try a restrictor in the return line
Looks great, just a couple of questions for my street car...
1. Do they run noticeably loud?
2. How's the return to center on your steering wheel when travelling?
Return is purely set from caster and toe so doesn’t effect it
They are noisy but if mounted at front of car you can’t hear it when the engine is running
@LogansSpeedShop cheers for the swift reply lads. I had my last street car almost fail engineering due to return to center issue. My s13 kswap will be running something simular to yours. Now I'm just weighing up, would I rather a volt drop from running a cable from the boot or running pressure lines along the chassis rail haha
@@alexwinterz if you wire it correctly you won’t see any voltage drop
@@alexwinterz also centring issues any good wheel alignment shops should sort you out , 7 degree caster ,2mm overall toe out is a good base for drift car
Just don't mount it on a firewall like I did, constant whine in cabin...
I am still confused in electric connection please make video on how to connect ignition or alternator ...or it works on pulse or current... explain
All the wiring notes are in the description too for you
Thanks for the vid. how long do they take to turn on if i connect both the small wires to acc power?
Its not quick and you can hear the pump struggling this way
Ok thabk you. I'll find a way to delay it, even if it's done manually.
Doing my first LS conversion, so im hoping there is an output there for the tuning gurus.
hey man I'm planning on doing an astra power steering pump conversion on my vt commodore, I know with commodores they are abit somewhat easier but is it all the same like wiring?
Yup the wiring will be the same
Such a great video!
Can they be modified to increase pressure?
I haven’t tried
I guess an oil cooler is on the return/low pressure line?
I haven’t ran a oil cooler with one of these pumps on multiple cars and never had a issue
ALMOST AT..
1K!
So close now !!!
Great video
Does the pump not need the control box that runs them in the factory car ?
Are they ok to be hard wired in with out the control box and will they work with aftermarket ecu
correct, no need for any other controller
Good video. Is the ZF pump also good?
I’ve never tried it , only this model
Great tutorial. Can you advise on what breaker you used. Brand specifically
Just one from my wholesaler
Hey mate thanks for puting the info in description im going to do the same on my FC rx7 just wondering did you just block off the other thread hole thats on the rack i think it was for a cooler line maybe, if so what did you use an thread size etc please ?
yup i did and i think its m12x1.5 from memory, best to double check
@@LogansSpeedShop thanks mate, appreciate it
Hey do you think need to run the oem cooler for the power steering fluid ?
I never have
@@LogansSpeedShop and worked fine ye ?
@@karolisskudra1681 no issues
Hello, I am going to install this steering pump in a car that has red steering fluid, in this case, what fluid should I use? Green or red? Thank you! 😀
I’ve found both to work now
Hello, I would like to install the pump in my R32 GTR. How is the steering behavior? Is there a problem with the carrier reaction or something like that?
It feels pretty good , I can’t fault the feel how I’ve got it in this video
I have one in drift car that I can’t figure out why at full rev it’s gets super heavy but normally diving it’s fine
Your alternator might be dying dude ?
How do I wire it to the ecu?
Use two hbo stepper outputs , conditional stage how they turn on
Thanks for the great info. Where can i get the M16x1.5 to -6 fittings?
Any good fittings store should stock them
Great video. I noticed there are restrictors, approx. Ø2mm in both the pressure and return lines. Do you run these? And if not, why not?
I don’t , and found that the pressure is good without
What hose ID would you recommend for the high pressure side?
I no always use 6an ptfe line
What size fuses do you need on the smaller electrical wires? (If any)
No fuses needed on these
Do you know how much pressure can that pump make? and can it be tuned/modified to make higher pressure than stock?
It is single pressure only and I have a sensor to put in to check but haven’t had a chance
Hey mate, what size front mount intercooler have you ran with this set up?
It’s a fg Ford falcon upgraded intercooler
What gauge wire would you recommend for power and earth
Minimum 8 , but I’d go 6 to be safe
@LogansSpeedShop much appreciated thank you
is it essential to use a relay on the little blue wire ? can I just wire this to a normal switch?
If you’d like you can but then you need to turn it on
Good day to you sir, love the video but i have a question, i have an 04' astra convertible and i run it in a slalom/autocross championship. I am continuously having problems with the steering getting heavy when steering repeatedly from left to right and i am losing time because of that. Any ideea what i can do or if i can upgrade the pump? If i put a vectra pump on the steering rack, will the seals blow?
sorry im not sure there, you may just have to have a look at how yours is powered currently
Sounds like overheating fluid
Run a cooler on the low pressure return back to the pump
Did you manage to fix your issue? My issue is the steering gets very heavy and the pump seems slow to react to turn up pressure and make steering easier.
Hi, how can I control the power(speed) of the pump?
Thanks
I haven’t heard of people controlling the pump flow on this model , why would you need to ?
You’d need to control the voltage to the pump through some kind of variable resistor. The higher the voltage the faster the pump with pump increasing the pressure in the system. Assuming you’re doing this to alter the feel of the system.
Reckon this’ll work on a YB swapped na MX5?
Can’t see why it wouldn’t
@@LogansSpeedShop weighing up this or a mk3 mr2 pump.
Love the tutorial mate! Just curious what oil you ran in yours and whether you had any issues? I’ve read mixed reviews and some say it’s better to run whatever the rack from the car needs and some say to run the oil specified for the Astra for the pump. Does it really matter? I’m on the tail-end of mounting this in my 1JZ 180
I have run both normal power steering fluid and ldas and seen no difference
@@LogansSpeedShop awesome thanks! After I commented I noticed you put it in the description but thanks for replying! What do you usually do with the belt-driven ps pump when you do the conversion?
@@jamesdude666 haha chuck it in a draw and hope I remember what engine it’s off
@@LogansSpeedShop hahaha nah that’s fair I just mean what do you do to replace the OEM pump in your system? Can’t remember what engine is in your 15 or your FC but I just did the conversion in my 1J 180 and because it’s a serpentine style belt system I have to fab something up to bring the belt back up high enough to go around the water pump pulley without fouling on the tensioner
@@jamesdude666 in your case I would just make a tensioner pulley up to replace it
Hi there quick question.i have a 2008 astra twintop 1.8 ... steering heavy an faint smell of rubber any ideas...much appreciated 👍
Mmm I’d be looking at getting a wheel alignment first
Ive done this conversation on my FC circuit car. Having problems with the pump speeding up and slowing down mid corner causing front wheels to turn slightly. This makes the back kick out. Is there a way to have the pump stay at a constant speed and pressure?
I’d be checking on your fluid temps , thst you don’t have any air in the system, and the voltage to pump is consistent
Did you manage to fix your issue? My issue is the steering gets very heavy and the pump seems slow to react to turn up pressure and make steering easier.
@@kennyconomos5222 yep ripped it out and put factory power steering pump in lol
Hey bud is there a specific astra pump you use ? Like a certain yet or model ?
98-06 ts astra
Mate you have a spare fc rack for sale?
I don’t sorry man
why are people doing this? are the indestructible?
They can be mounted where you want , fresh lines , work better than stock pumps in most situations and they are consistent
as there's no belt driven pump also less rotating mass on engine for better response, which also means better fuel economy as the electric pump is more efficient. Plus, you can make variable-assistance steering so heavy or light when you want.
