Hey all, anyone fitted one of these EPAS kits to their GTR? I am going to get rid of my r32 ps pump. I couldnt believe how heavy it was when i pulled the motor out. Looking at how else to optimise the power steering system.

Any feedback on how good they work? How easy to setup for racing purposes? Issues with front wheel drive?

cheers

Have you ever driven a car with factory electric power steer? Ever noticed how it has absolutely no feeling at all and how you'd be better off whacking a bowl full of custard with a horse whip?

What makes you think an aftermarket EPS is going to have any gope of feeling even a fraction as good as those horrible factory affairs?

LOL at the custard!!!!! I Didnt think of it in those terms. I noticed the bc auto car replaced his factory pump with a merc electric pump successfully. That gave me inspiration to do the same. Then when looking for a elec pump I stumbled on this. I dont have an opinion on it having never experienced it. Perhaps a simple electric hydraulic pump exchange is best?

I think it would be best IF you are dead set on upgrading. I thought that's what the link was all about of first then realized it was actually electrically assisting the steering shaft. I think you would definitely lose a bit of feel through the wheel with this

So is the reason behind pulling the power steering pump out to save weight? If so I would suggest considering a pump that eliminates HICAS (unless you are using it, wouldn't think so but) because the P/S pump in my R33 doesn't feel awful heavy

Have you driven a vf?

You would be hard pressed knowing it's an electric rack. Granted the commodore aren't the best handling things out there, but our Calais wagon is great to drive even with its woefully small rear sway bar.

I've driven an old BMW with no power steering or power assisted brakes and once I got used to it was one of the funnest cars I've driven. No power steering has its down sides of course but the steering feel was great.

I'm not a fan at all of electronic steering, it is personal preference to a degree though. I hate electronic throttles though, I haven't driven a car with an electronic throttle that I have liked yet. None of them can quite keep up (or the way the engine management works with it) enough for me to enjoy it

Doubt you'd compare this to a road car system!

Once you add the ECU, harness plus the power assist unit, probably closer to 10 than 5k on price too. Believe the Cootes have one in their car, so high downforce and lots of castor is probably where it would shine.

      Misfire/stalling issues

      By Duncan · Posted

      well, to check fuel pressure all you need is a gauge and a 8mm joiner with a gauge port in the inlet fuel line; if it stalls at idle when hot you can open the bonnet and check pressure at that time; the fuel pump is a potential cause for what you are describing but it could also be wiring to the pump getting hot. You haven't mentioned that the factory fuel flow control on the fuel pump earth is removed. So either way, it is worth running a suitably sized and fused wire from the battery to pin 30 in a new relay in the boot.  Use the ECU trigger wire into the standard fuel relay to pin 86. Earth relay pin 85 and the Fuel Pump negative (nice big wire for the latter too). Run relay pin 86 pin to Fuel Pump +. That will remove multiple possible fuel pump wiring issues in a 30+ year old car

      I've been running a 525 for years with the standard hat and FPR in the stagea (mine has a 32 gtr fuel rail and stagea and 32 hat and tank setup are the same) without an issue with base fuel pressure. You said when you disconnected the return it is OK, did you do so at the fuel rail or the fuel hat? Either way I'd be looking for blockages or in the case of the tank kinks in the lines downstream Note I did however have an issue with the current required for the 460 melting the fuel hat.

      I'm trying to maintain stock appearance . Hicas is still installed (although has lockout kit) did you retain factory fuel pump hat? If so I assume you used a bulkhead fitting or similar ?  I was also trying to avoid a full re design as it was previously dynoed at 426kw atw with same setup but different pump. Changing return line would also mean having to change ethanol sensor and fpr and possibly fuel rail. Not chasing more power in any way just reliability of the setup

      Misfire/stalling issues

      I do think it's weird I had it for 2 weeks then the issue came up out of nowhere and progressively got worse. I would've imagined changing everything in the ignition system would've resolved any ignition related misfires but still has the high rpm and idle misfires that seem unchanged. I would've thought if it was fuel related it would happen all the time unless it's the pump losing pressure when it gets hot. If it was the ecu I would think it would do it all of the time.  Something I noticed when I had it all apart was a pretty decent coating of oil in the J pipe coming from the throttle body. The weird thing about that is the pcv that goes to the intake is blocked off. So that has me wondering if the oil is coming from the turbo because that's the only thing that could get oil in there. This thing does sound like it spools like a mofo like I'm a former dsm guy and the only stock turbo I've ever heard spool this loud (to only go up to about 5psi) is on a diesel truck. And the recirculated bov is really loud too I had a TurboXS RFL and this thing is just as loud and being so low on psi seems a little weird. I don't know if any of this is or isn't related but just trying to make sure I'm not leaving any potentially helpful information out.

      So latest update. I replaced the ignitor with a jspec unit from enjuku. It felt a lot better at first although it is a little bit cooler of a day than it has been. Warming up didn't have as much misfire sputtering as before. Went on a 10m test drive. Felt good, a lot stronger though I was taking it easy on the boost. On the return trip started getting the cutting out at higher rpm again and was getting worse the longer I was driving. Took it easy the rest of the way home. Before turning the car off was getting the normal idle sputtering I was getting before.  So where I'm at now, entire ignition system has been replaced with upgraded components. Plugs still gapped at .8mm. Removed the fuel cap in case it was building too much reverse pressure I'm the tank, didn't help at all. Now I'm still on the same tank of gas the fuel treatment was in, I'm thinking if I can run that out and then refill with fresh 93 maybe  the treatment is too concentrated in some areas but doesn't explain that it only does it once the car is warm. I'm leaning towards fuel pump or injectors but if the injector was clogging I don't think it would make it shut off like it has but then fire right back up like nothing happened. So my current guess would be the pump. Without a fuel pressure guage no way to test or check it while it's running.  So that's kind of where I'm at. Need to start testing fuel components and ecu/wiring but I'm at a loss of what's the next logical step and procedure for testing it.
