I would personally leave the stock pump in and fit the new pump in line. The stock pump would work as a helper. I would also suggest fitting a light pre-pump filter to save your new pump from any risk of damage!

But then again, there is more than one way to skin a dog (or cat for that matter :laugh: !)

I did my Bosch 044 myself a few years ago because my mechanic didn't want to do it. Hard to get the right fittings etc. Also it was very difficult to get the pickup right down into the bottom of the tank. A dodgy install will pickup about 1/4 of the way off the bottom, so you tend to run out of petrol at that point and get fuel surge (read: leaning out) at more than that when you corner fast.

In fact when I first installed mine I had that problem (but at just below the Empty line) and I could first tell it was a problem when I went around a corner and the engine cut out momentarily. I wasn't flooring it though so luckily no leaning out problem. But I ripped it out and installed it properly. I had deliberately run it low to test and see if I would get this problem.

I don't have any photos because I lost them, but the exact same pump is doing a transplant within the next few weeks so I'll definitely make sure I get photos and post them up while it's out.

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      Coolant leak?

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.

      Is it alright to top up with just another green coolant?
