Same here, Nismo lift, 2x044s, surge tank, twin entry rail, ID2000s, lines front to back etc etc.

My mates GTR made high 500awkw before they put a 3rd one in. Now makes 720awkw :P

Well thats a little comforting!

You should be able to fit 3 in (I've got 3 in mine), how is it currently setup?

Nismo lift into surge and both 044's mounted on the surge. I was discussing with Steve today that IF it comes to it we might have to make a bracket and mount one next to the surge. Thing is how do we merge the 3rd pump into the 2 lines? Hmm?

^^^ with any luck I will have the results on Friday arvo. The good thing about this is there will be two maps done.... 98 and E85. Same dyno, same tuner, same setup 1 day apart.

I did a 98 map and one for avgas mix same dyno about 25mins apart. dont remember injector dc tho.

Went from 420rwkw @ 19psi to 475rwkw @ 24psi. And then we picked up on the oil problem that resulted in a bent crank...

RB30 crank. Nothing special. The workshop that fitted the engine here in Tassie hooked the oil cooler lines backwards so oil was pumped to the wrong side of the filter relocation kit and things were a little starved of oil.

Thats what I said. When its marked "in" and "out".

Its a shame as the engine was going to make some good power. The engine was built and shipped here so only needed to be fitted. I was going to fit it myself but didnt have the time. I wish I made time now. lol

Its been sent back to the builder for a new crank and whatever else is needed to get it up and running again.

Next tune will be on E85. Thats why im interested to see what everyone else is doing.

If I need a 3rd 044 then so be it. :)

Ok so Paul and I were talking about this in depth tonight.

We are both concerned about max flow for big power but the empty surge tank thing is a huge concern aswel so we will test that first

We are going to take the pump off and test the flow properly, we will post up accurate results (will be on e85) as it seems no one else has this info.

There is another option from 3 or even 4 044's. I use 2 x Pierburg pumps on my GTR. out of 1 dash 6 line (my return from my reg) at 40psi I get 12.5 liters a min. The also are a sucker and a pusher so no need to have them fed by other pumps. Has seen around 610rwhp with no dramas at all. They are ethanol/methanol friendly as well.

I actually have no surge tank, but have 2 x Dash 10 lines feed into my tank with strainers connected directly to the fuel line.

Obviously if I have descent G's and under a 1/4 of a tank I will have issues but until then I can hold it flat for ages and not have a drama.

Always handy if you are towing a trailer, up a hill in the sand :)

does anyone run a low level switch in their surge? if there was a spot inch or so above pickup connected to a simple warning light might give piece of mind down the strip?

i think on circuit it would be a good idea , but just for strip i reckon u have some massive problems if u can empty ur surge in 11 secs or less

Here is a new issue. Over filling over the surge tank. Now having 2 044's feeding the engine not all the fuel is going to be used. The fuel heats up and expands..... Has anyone split a tank due to excessive pressure?

There is a thread on the pommie forum about this. The line back to my main tank from the surge is the same as the incoming return..... Maybe I should have made it a few sizes bigger!!! BAH!

i have a small tranny cooler from super shit in my return line, works well. before that the pump used to start cavitating on hot days after half an hour or so of light driving, now it takes a really really hot day for it to do it.

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      R33 GTR running -9 with no tune

      By Murray_Calavera · Posted

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      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
