Got the pump from the UK today finally.

I found some great info on this install. There are people with all kinds of cars using these things.

Firstly, here's the pump (cleaned up). Complete with pigtails for the harnesses:
Image
I have had a couple hoses made for my existing pump and I now have hard fittings on the rack and the pump with a hose in between - all connecting with 6 AN fittings.

So I found a fitting that uses 6AN for my existing hose and 16mm x 1.5 for the pump:
http://www.summitracing.com/parts/rus-670531

I also bought a 90* fitting so I could route the hose down:
Image
Image

So now I will get it wired up and try to install. I found these diagrams for the wiring:
Image
Image

I bought this relay kit and hope to get everything working this weekend:
http://www.amazon.com/Fastronix-Weather ... ge_o01_s00

Lastly, it occurs to me that with the PS pump eliminated, I will have eliminated my Viscous Fan, Power Steering Pump and AC Compressor.
The Fan pulley and AC Compressor are currently on the engine as rollers but I now will just have the alternator on the serpentine belt. I'd love to get rid of the extra stuff and make some more room for air movement.

See here:
Image
I can pretty easily get rid of all the stuff in the Red X's but the Blue one is tougher. I'll need to figure out how to tension the serpentine belt by likely moving the tensioner.
I will need to cut off the little bracket that the timing tools fit into so I guess I'll just source another belt cover if I ever decide to change the timing belt again.

Found Marc's solution to the same problem on his V8TT Coupe:
This would be PERFECT.

A turnbuckle as a tensioner.

Thats a great idea for sure. You could always get a machine shop to make something up more OEM like if need be.

I ran mine with the factory tensioner and kept the fan pulley as an idler. Will post up a pic.

Thanks Kieron,

You are using the viscous pulley though- I'd love to omit that too. My fan sits right on it. If it were gone I'd get a pretty big increase in airflow.

Kieron, do you happen to know the belt you used here? I may well use this setup until I figure out a way to omit the other pulley

The more I look at this, I think I can do it without relocating the pulley like Marc did in his pic above.

Image

If I use the yellow line routing, I just need to turn the tensioner into a pusher rather than a puller which can be done with a turnbuckle!

I have a lot of work to do this weekend to get ready for Carlisle.

The MR2 Power Steering Pump
re-routing the serpentine belt and removal of the AC compressor, PS Pump and two other pulleys

That will not work well, the tensioner needs to be on the slack side of the belt right before the crank pulley. You have it on the drive side where it will just compress and everything will slip. Marc using a solid turnbuckle would not have this problem

Made some progress today

Got the 80* thermostat installed. It has no hole - I know some people swear by the hole and even drill a small hole in thermostats that come without. What do you guys think?

Also, got the serpentine belt re-route done. It was right at 100cm
Image

Image

How tight should I make the belt with the turnbuckle?

I also got the euro bumper fitted up finally
Image

I have almost everything ready for the MR2 PS pump install. I need a couple AN fittings and he bracket to mount it and I'll be good.

I hope to wire it all up tomorrow in advance.

The belt in the B6 S4 is kinda similar, and the tension pulley doesn't have a spring of any sort. That application you just make it taught with your hand strength and then tighten the adjustment bolt.

I made some more headway today.

Got the Power Steering Pump wired and relayed. Tested it and it fires up. I have it triggered by the ignition switch so it will be always on.

From what I understand about this later version, it senses the resistance on its own and dials back the pressure when it's not called for anyway.

I decided to drill a 1.8" hole in the thermostat and got it all back in there. Loaded it all up with coolant and bled the system and ran it a bit.
The Alternator and new serpentine belt seem to be working just fine.

Unfortunately, The Euro Bumper isn't going to work on this car. It was fitted up yesterday with the radiator out and with it back in I would need to do a lot more cutting than I want to.

So back goes the old ugly bumper.

I did finally get around to figuring a way to install the strips below the headlights. With the large radiator in this car I had to cut off the ends of the headlights that hold them in.
I cut the ends of the strips off and put a screw through the little tab on the bottom into the headlight itself.

Small victory I guess, but a victory no less.

Once the fittings for the PS hose and a bracket I ordered show up I hope to be done screwing around with the engine bay for a while.

Looks great with the trims! And of course nice work on the belts, interested to see the long term results.

Seems like you'll have to go R/S2 or Euro V6 for your bumper needs if the Euro Coupe is no good?

Thanks!
That's what I'm thinking too. Since this car is really an ugly duckling, I'll likely just leave the NA spec bumpers on it.

I made more progress today on the PS pump install.
The bracket I ordered showed up today from a guy in Montreal that made a few:
Image

I painted it Tornado Red (with my trusty paintscratch.com spray can) and put it in place:
Image
Image
Image

It's a little close to the exhaust manifold for my taste so I took some spare sheet metal and cut out a little heat shield. It's a little hard to see as it got dark:
Image

I'm all done other than a couple fittings to finish the install. They arrive tomorrow and I hope to god this works.

cool! I'm interested to see how it works. Maybe you said this earlier, but given that you got a bracket that was pre-made I'm guessing someone has done this before for this application?

I know some people have used the earlier version of this pump that doesn't have a reservoir on their cars - (Marc, Greg W).

The writeup I used for info and the source of the bracket was this guy who was installing it into an Acura I think: http://www.k20a.org/forum/showthread.php?t=58599
I'm guessing he makes the brackets. From that thread, It looks like he had some kind of pattern for it.

Actually, I don't have one in my car. Jim Green does. I know Marc used one due to limited space with the twin turbos. Jim Green uses one to eliminate the need for making a bracket off the motor. If I am not mistaken, I think Petar used one too.

I hope to bring this to Carlisle assuming everything is working well. It's a 7 hour drive and I REALLY don't want to get stranded in between here and there. If it's being difficult I'll have to bring the Cabriolet again.

Re: Re: Ben's V8 CQ - MR2 pump Success!

Postby Grillage » Wed May 04, 2016 5:25 pm

It all works!

I finally got the last piece I needed today. I ended up going to a local hydraulic shop and having them make a long hose that would replace my existing hose and an 8" extension for the hose in the car rather than a whole new line. I didn't want to make two trips if one approach didn't work.

I ended up using the extension first because I didn't want to pull the intake manifold and all associated stuff again to get to the other end of the hose.

After a quick bleed (all with the engine off too!) I was good to go!
It's a little stiffer steering than stock but no noise and very smooth!

Makes a BIG difference in the way the car drives. Carlisle here I come!
