I know I'm late to the party but I thought I'd show the new muscle
Yes, it's under a deck, yes, those are old ski's on the bottom of the pallet, and yes, there was like a foot of snow when it made the trip from the donor car to where it sits now. Shout out to my buddy Alex for helping me get this thing into a safe spot until my spring semester is over, and to my 4Runner, to which we attached a tow rope and used to pull the "Sled" out back

I'm trying to figure out a way to do an electric PS pump in hopes of keeping those. There's a guy on here who I think used either an MR2 or TRW electric pump with fitting conversions.

The part I cut off is where the factory engine mount attached in the transverse application . The power steering pump mounts where the AC compressor used to be now . My AC has not worked in the 3 years I have owned this car and I have not really missed it . Besides , don’t need AC because of two words ,,,,,, race car 😆

Actually by sheer happenstance, looking at all the electric PS equipment in online stores, I saw the S40 pump along with the Mazda 3 and Mini pumps. Thanks for the bump in the right direction!

the real problem with E-PS is the electronic **** they use...
but some of those motors might be able to be disassembled and "hotwired".
years ago i put a fan from a volvo S60 onto my 944...it came with a PWM controller box.
but if you opened the box up there was all the fancy circuitry and purple wires...and 2 big stonkin power/ground leads.
wired it to battery via relay and 944 fan switch, worked just fine.
a standard belt-driven PS pump runs 100% of the time at low pressure since youre mostly driving in a straight line.
it only makes real pressure when you're going slow on the steering locks.
since the 944 PS rack has valving to assist based on the direction the wheel is turned, i'd think you could just run an electric pump 100% of the time (maybe put a resistor to slow the speed, like the fans?) and it'd just bypass flow like standard until you turn the wheel. would probably need a decent PS cooler though.

It looks promising. Hook up 12V & ground to the input and one 12v to one of the CANBUS pins (I forget which one) and it runs drawing around 6-7 amps under no load, and 20-25 amps under turning.
With a decent cooler like you said, and run it around 70-75%, I think it's a viable option.

7. I do not recommend installing the stock 07K coils. They could potentially hit the bottom of your hood. They just barely clear the hood on my car, but for a better fit, I recommend getting the shorter coils from an Audi S4 V8 (B6 or B7), which are about 7 mm shorter. PN is 077905115T. You need to trim the rubber boot to fit the valve cover. This will be detailed in the instructions.
[and vr6 TB stuff]
Alan, are you planning to sell the throttle body and coils as part of a future phase or these parts we should get hold of on our own please? if we're sourcing them, might you have a part number for the VR6 TB please? (Looks like it was fitted to a few different years and models of cars and don't know if there are any differences). Thank you! The quality of the kit parts is absolutely incredible by the way.

I'm thinking the same thing. Been reading this thread here:

I don’t plan to sell the coils or TB since they are standard parts that can be sourced easily elsewhere. Same goes for the 1.8T PS pump (PN 1J0422152G).
Thanks so much for the feedback, really glad you like the kit.

Edit: Maybe something like this?

And like stated before, use something to control the potentiometer for pump speed like an Arduino.

Aaron, the PN for the throttle body I’m using is 021133064A. I believe it’s from a ‘96 to ‘98 VW Golf, Jetta, or Passat VR6.
