Hello from Canada, new member here!

I imported an r34 sedan in the summer of 2020, it is an hr34 (rb20de) but the previous owner swapped in the rb25det neo and trans. I am now wanting more power, around the 350ish mark. So far I have r35 gtr 570cc injectors and high flow turbo. I just have a few questions:

1) For the fuel pump, can I get an r34 gtt fuel pump or is it different from a non turbo (hr34)?

2) ECU wise, I'm thinking of going Nistune type 4 board as a standalone is above my budget, good choice?

3) How much torque can a stock r34 gtt clutch handle? 

Any answers are greatly appreciated 🙂

Just put a Walbro 255 or similar in it. You need more than the stock GTT pump anyway.

Nistune is the correct choice for a not-expensive-but-capable ECU.

You will need to upgrade the clutch, the brakes, and the diff. If you still have the open diff, it will suck.

My bad, didn't mean put a stock gtt fuel pump in. I was looking at the Walbro 255 made for the gtt and just wondered if it would work on an hr34

Its worth mentioning that this is one of the things that don't really have write ups as they are generally pretty trivial. Don't necessarily go overboard because if you really need to beef up the wiring the stock fittings may not handle the amperage that an upgraded pump will draw.

Generally however the stuff is fairly trivial to fit unless you're really going for a BIG pump.

I never noticed any difference in the plug/wiring/general setup between the non turbo 34 and turbo 34 (but my non turbo base car was a 2.5).

Either way, it'll become apparent when you pull the current pump out as to what needs to happen by holding them side by side. It's always a good idea to get 14V to whatever pump you do choose, which is a seperate task but again not overly complicated and should* be documented here.. somewhere..

      Mistakes were made, my R34 Story

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

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

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.

      ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.
