yes! That is the only reason I bought a sard reg over the nismo one. I wanted to have a fuel pressure gauge tucked away with a warning light. a fuel pump has died on me once before, and I'm paranoid about it now (and fuel surge too). the beauty of my sard reg is the defi sensor just plugs into the side, and when setting it up I can hit a switch on the defi controller which eliminates boost/vacum from the reading so I can accurately see the base pressure withiout having to unplug the vac line etc. :)

but yes, you can t one in, just a bit of mucking around.

I'm guessing with the NISMO one you can't install a pressure gauge and a warning light/device?

Nice choice of hardware :D

Interested in which button you press on the controller and its effect? Shouldn't turning key to "accessory's" give you a base pressure

turning key to accessory wont give you anything sadly. turning the key to on will prime the pump, but only for around 2 seconds and i think only once every 5 min or so. (ie you can't keep doing it over and over).

on the controller you press both the up and down button at the same time and it gives you what they call 'differential pressure' which is fuel pressure - manifold pressure (either positive or negative pressure). This gives you the same effect as removing the vac line from the reg to set the base pressure. but you need the defi boost gauge installed too to use that feature (which I do anyway).

marco, the nismo reg does not have a gauge port sadly. so to install a guage you will need to cut the fuel line and install a T-piece and a gauge off that.

The R34 should be no different to the R33, if so it will be so marginal you won't care.

Just read the R33 thread.

The pics speak for themselves.

Price on Tomei pump (Someone asked) was $340 deilvered from nengun and i suspect it's now cheaper as the dollar has gone higher.

Good luck peeps.

Cheers Birnie for the help, nice pics you posted too. Should be very helpful when i buy the pump!

Beer Baron is that a feature with the DEFI II controller or the earlier one too knowing that I might be tempted to go sard anyway.

Wasnt aware they did differential as well!! Thats damn cool really am running a defi boost too only I have the early controller.

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Could be falling edge/rising edge is set wrong. Are you getting sync errors?

      Jacks that fit under GTR lips that can reach the subframe?

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Mistakes were made, my R34 Story

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
