Fuel Pump Uprgades For R33gts25t ?


Recommended Posts

Hi all , I'm a bit confused about R32/33 GTR fuel pumps and std internal tank surge chamber . I one saw a picture of the R32GTR's surge chamber and need to know if the R33 GTST has this as well . I understand the R32/3 GTR pump goes into normal R33's and is a common upgrade . Are the GTR pumps poisonous to buy new and is the 33 version a higher volume pump ?

BTW don't need anything over the top just for absolute max 270/280 Kw .

Cheers A .

Hey thanks for that crack , the Nengun ask seems pretty reasonable I reckon . I'll PM Performance Wise as they gave real good price on my PFC/Boost control kit . If his ask is sort of similar I'll have one .

Can you keep me posted when you fit yours

Cheers Adrian .

PS. Id like to see that "pressure relief valve" because to me it looks like a pulse damper sort of like what VL's have on the external pumps mounting bracket .

I did the same thing, but got a nismo in tank pump (from nengun). It comes already fitted on a bracket etc, it was just plug and play really. Just slide the old one out and slide the new one in. I had fitted a walbro but when everyone started bagging them I thought I'd upgrade.

Only if you manage to get the pump cradle.

The problem with the gtr pumps is that you're replacing an old pump with another old one. Unless if you get one off a car with very low genuine kays, it's not worth it.

A pump is verey important. If the pump dies suddenly when you're wot, you'll kill the motor. If it reduces in flow over time, it can also make the motor run lean for a period of time and also kill it.

Keep in mind, that the reason why we're upgrading pumps is because we want to put out more power. We're going to need more fuel flow than stock becuase of the extra power, so if it dies, it'll be more dnagerous.

A new gtr pump wouldl be an excellent choice, but from nissan, the price is similar to the nismo/tomei pump.

    • Done few measures to work out how I'm going to fit the Thermotec Exhaust Jackets to my headers, the kit comes with 8 steel zip ties and 80 clips, enough sleeve to cover each primary 600mm(24"), thus having a clip every 75mm. I test fit one of the primaries, the sleeve covers my 1 7/8 primaries well, and when the clips are on (I didnt use the clips, I used some small stationary fold back clips), there isn't any gaps which is nice. Looks the goods so far. Just need time to do final fit up, and then take it for the typical "smokey drive" until the sleeves "cook off" the manufacturing residue like the normal heat wrap smoke show. The hard part is covering the No1 primary on the 4:1 headers that obviously is bolted to the car and ducks behind the other primaries, I assume I'll be laying on my back playing "elastic man" with my arms Also purchased a few electrical glands to run the RaceTCS wiring thru my firewall as I cannot see a neat and easy way to jam the cables through any existing "holes", 3 x 16mm glands to suit 5-10mm cable, the CAT6 cable is 5.5mm and the 2 ten cores are just on 9.5mm, tight enough to keep the moisture and engine bay fumes out. They will hopefully fit on the firewall on the passenger side without to much fuss, I've had a quick look, but there will be alot more looking before the 16mm holesaw gets to to play. I'm still waiting on a rough quote from Autotech for the actual termination into the PCM and ABS modules, whilst the actual job isn't rocket science I would prefer to "pay cash" to someone with more wiring skills and proper tools for the job than me. My wiring skills stop at buying the wiring, the Deutsch connectors, drilling the holes in the firewall, and fitting the glands, any more could result in fire, or possibly bay windows in the block. Why am I drill holes, I need to feed in 1 x CAT6 from the ABS module into the cabin, and 2 x 10 core, 1 x 10 core of 8 injector out, and 2 earths, and 1 for 8 injector  in for the injector interceptor wiring and a power. I will be heading into Autotech to get approval for my cunning plan. So many coloured wires and tapping into to ABS and PCM makes Mark's head hurt......... I pay cash now..
    • https://www.jdmgarage.com.au/shop/engine/engine-accessories/oil-caps/genuine-r32-gtr-oil-cap-15255-d5501/ That says non neo rb25, I just though maybe it didn't clear the plastic cover or something 
    • Now with a fresh alignment, a lot less toe in at the rear now as it's no longer needed (subframe offset by 10mm upwards). Front toe touched up and I think I'm some what ready for All Jap Day, which might end up being cancelled due to the rain.
    • 4D table allows you to say have the slider at 0%, 25%, 60%, 80% ethanol as an example, giving you multiple maps if you will. Also removes the need to do arithmetic when you're tuning, no need to go ahh I need to add 11 to my base table cell of 8 to give me 19. I "think" it makes tuning a bit easier, however still yields exactly the same results as using the conventional compensation tables as you and I are both well versed on.
    • We're setting the backlash. "Shouldn't" need to change it as the same front centre, crown wheel and pinion are going back in that came out of it but we will see.
