Hey guys.

Currently in process of installing Nismo intank fuel pump on the 33. Working off the tute in the diy section. Everything was going to plan until i put the new pump back in the hole. I cant find the spot to actually mount the bracket inside. When i pulled the original pump out it didnt appear to have the mount part holding onto anything either. It is sitting right at the bottom of the tank part. Am i pretty safe to close it all up and leave it go? Or is there issues this could cause (maybe like fuel surge if the pump moves (even though it seems fairly steady).

Secondly. With the black ring that you have to tap around (with wood and mallet by the tutorial). A few of the tab bits are starting to dent a bit. Has anyone come across a better method to tighten the ring over the lid???

Thanks for any help.

ps if anything doesnt make sense im a bit "fuelled up" atm. :) lol.

Cheers Luke

the bracket has like 2 forks on the bit thats at rigth angles to the main bracket . these slide into 2 slots on the front wall of the tank just inside the whole .

get a blunter screw driver

ive seen pics of people using big multigrisp on the ring thing. god that gave me the shits putting it back on. too fiddly to get off centre.

also, it may take a lil while to get it on the mount. took me around 10mins of constant trying. you'll get it eventually :)

Thanks for the help guys.

Pump is in. Car is running again (cant take it out of the street to test as No interior or seatbelts atm. and i dont have a milkcrate to use as a makeshift seat :(

For peoples future reference. My ring was getting a knocked about trying to get it back on. (No funny comments there please ;) ). Ended up putting a bit of inox on the inside thread of the ring. Went on like a dream, then secured fine once tightened.

Literally took about 2 minutes to finish off.

Cheers. Luke

Well. The car finally left the garage with the new pump in tonight. Running fine. Ive read the nismos are fairly quiet. This thing sort of howls. lol. Admittedly with no back seat or sound deadening. But wow. Sounded pretty tough though i must add.

Is it normal for nismo pumps to be approx double as loud as standard??

Secondly. I know i dont need a tune straight after getting the pump done. But if the car was running perfect before the pump. Am i fairly safe to be revving it right out on the new pump without affecting tune at all???

Thirdly (full of questions tonight). With a power goal of approx 250rwkw. On the Nismo pump should i be doing the wiring upgrades to make the most of it??

With a power goal of 250rwkws, you'll be fine with that pump as is, no wire upgrades.

As far as tunes go, if your tune was fine before, and you've upgraded your pump.....all i can see happenning (and that's a maybe) is you'll be getting slightly more fuel which is actually safer so rev to your hearts content.

just make sure you did secure the pump to the bracket inside the tank. otherwise you are going to get fuel surge issues and possibly damaged/dead pump eventually.

    • Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.
    • Does the scanner do all the CUs in the car, or only the ECU?
    • @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man
    • Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?
    • Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
