Mugabetown - Whoretownin' At It's Worst.


Recommended Posts

Nismo fuel pumps are only 275lph or something silly. Sure they bolt in but thats about it. 450lph walbro pump will also cost ~150 bucks less IIRC. If the R33gtst fuel pump mount setup is similar to the R32gtst it's a peice of piss to modify it to fit, though getting to the tank may be harder due to 33's being less likely to combust in a rear end accident.

You could probably easily go smaller injectors (720cc?) and shave off a hundred bucks. Also make sure you buy side feed injectors to suite your fuel rail, with the right size holes etc.

Really need a FPR? Making 300kw's here without one, but maybe there's different stuff on the GTR fuel system?

I wouldn't double the tuning, maybe add only 50%, for flex. You're basically getting two tunes in there. That's assuming you have no issues however, which can quickly add up unfortunately. I mean, best case, just a 98 tune, 500 bucks maybe. Worst case, things to wrong, flex tune, 2000 bucks isn't out of the question, so be ware.

you're also just missing little stuff. Turbo gaskets, new studs, fittings for Ethanol sensor and the like can add up to a few hundred bucks

You'll need to figure out how you're going to get the car to the tuner aswell, Everything you need to do is easy enough to DIY at home (and... satisfying to do, i'd recommend it), but with bigger injectors the car will be undrivable unless you can get the tune adjusted for the injectors. Not sure how easy haltec is to modify

Not compatible? So Walbro over Bosch 040?

If you say so. You've done it recently.

yeah, the Walbro pump is E85 ready and as Pete said flows more than nismo pumps.

It can be fitted in tank too (just like mine)

Yeah, budget for at minimum 2k in tuning costs with eflex

R33 fuel tank is completely different to R32, just FYI.

Not sure how simple it is to mount a walbro/040 in tank in an R33

well as long is its not mounted to the tank floor it'd be easy enough :woot:

    • I thought that might be the case, thats what I'll start saving for. Thanks for the info 
    • Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.
    • Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
    • My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
    • There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
