T.D

Yeah, the Walbro does use a sock but I've read more negatives than positives from other people's experiances. Otherwise, I woulda went the the Walbro hehe Anywayy, I called up Bosch and they don't recommend that the 044 be used in-tank as it can't be submerged in fuel and to go the 040, yet there's quite a few people who have done so with no problems. All these dilemmas on me wanting just an upgraded fuel pump. FML. Oh, and the 040 is the same diameter as the 044 (60mm). Only difference in size is that the 044 is 196mm versus the 040 at 169mm.

Oh ok then, fairrr enough. Yeah, the 044 is slightly larger and it's meant for external mounting but the only reason I've gone for it was because I get to use the sock attachment lol Hmmm..... that's kinda annoying for me then, cos after reading other people's experiences with them, they were complaing about it so I opted for the 044 LOL DAMN IT!! Hahahaha I've got the 044 on order but it hasn't been dispatched yet, so do you think I should get them to change it over for the 040 instead, provided it's possible by them? Or should I just stick with the 044 and get it to fit by working at the bracket? I highly doubt I'd find the limits of the 040, let alone the 044 (aiming for only 200rwkw until the turbo gives way and a high flow is needed). Like I said, only reason I went the 044 over the 040 (and Walbro) was because I could use the sock attachment lol

I've read that some people get problems with running with 1/4 tank or conrnering as the pick up isn't low enough so it starves and cuts out. The mesh on the sock of standard pump is much finer than the metal gauze of the 040 isnt it?

I'm not sure to be honest! But I'd presume it would be slightly bigger as the 044 weighs 1030grams whilst the 040 weighs 930grams. Ahhhh k the, yeah I read one way to get around the 1/4 tank problem is to run the 040 lower, but you run the risk of sucking up all the crap on the bottom of the tank?

Oh ok then, I'll give them a try then. I'll also give autobarn a try cos apparently they can do Bosch stuff on order too (Y) Hahaha sounded like me at the very beginning of my research If you follow the tutorial, it seems pretty straight forward, but I understand what you mean though, cos I'm lacking the confidence to tackle it myself hahaha maybe try someone on the forum who has done it to give you a hand. That way you get to watch and learn, and also not have to pay the extra amount for a workshop to do it

Hey mate, thanks for the heads up, but I've read through the DIY/Tutorials (before I began researching, I had ZERO idea on fuel pumps and how to do anything regarding it, but after scouring the forums, I know how to do it but need that little bit of confidence that someone experienced can bring lol). Cheers for the suggestion anyway Hey mate, yep it's an external one but I'm mounting it in tank. Quite a few people are getting great results using it in tank as it allows you to use a standard sock arrangement (would of chose 040 but I'm not a fan of the metal gauze bottom, which can't use the standard sock arrangment). So for me, it was either the 044 in tank or the Walbro...... (p.s I've read ALOT of topics about Walbros and in almost all of them, you always appear and mention how it failed on you LOL )

I say its a compromise because I get to use the sock, but not having the ease of fitting like the Walbro unit lol Oh ok then, what sort of fittings do I need? LOL yeah I realise the 044 is overkill for 240-250rwkw, but I thought that any un-used fuel would come back to the pump anyway, as Yeedogga mentioned above. Thanks for the input though Thanks for the info, I'll look up more regarding cavitation as I haven't read too much about it before

Hey, I need some help installing a Bosch 044 (in-tank) into a S2 R33 GTSt. I know roughly what needs to be done, but would like some help from someone who has done a pump install themselves. Obviously, I'm happy to reimburse you for the time taken ($$$ OR ). I'm located in S.E of VIC but I'm happy to drive to you (unless you're on the border of NSW and VIC, which in that case I'm going to decline unfortunatley) Either reply or PM me if you're able to help me out

Ok, so I've made up my mind to get a Bosch 044 and mount it in-tank. Reason being I can use the standard sock arrangement and not have surge problems when running low on fuel and/or cornering. From what I've read, will take abit of wiggling to get it fitted but I guess it's abit of a compromise between the 040 and Walbro lol Now my new problem is, is there anyone in VIC who has done a pump install into a R33 GTSt and can offer assistance? I'm happy to pay in cash or beer, whatever suits you lol I'm not too keen on getting a workshop to install it because: 1) I want to be able to see what and how everything is done, so if later on down the track I need to remove the pump, I can do so confidentley. 2) I'm gonna get charged a decent amount of coin by the workshop. So if you can help, let me know

I have spent quite literally hours searching through threads regarding fuel pumps. I'm not interested in a 044, but am considering between a 040 and a Walbro 255LPH. Thanks for the link anyway Thanks for the info regarding your experience with the 040. I read that the Bosch unit will be too big for the cradle without cutting and bending the cradle. The other thing is, I want to run the standard nissan sock as it sits at the optimum angle and depth, hence why I'm leaning towards the Walbro unit as it can re-use it without too may dramas

Still looking

Alright then, no worries. I'll keep the sock reg and injectors for now then. If my budget extended to it, I'd go the Tomei as after searching through the forums, they're a perfect replacement. Unfortunatley, it's abit out of reach so I'm just going to have to make do lol Is there any reason why you choose the bosch over Walbro (personal preference or is one inferior to the other)? After scouting through the RB25 dyno sheets topic, I noticed alot of people using either of the two. Oh ok then, but doesn't that mean the fuel pump is likely to burn out if it's running at a higher voltage constantly? Yep, looks like I'm keeping the stock reg and injectors until I decide to push the envolope further with a Hypergear high-flow, Yeah that's what I've been reading too and is why I'm sorta leaning more towards it. So with the Walbro, I can use the stock nissan sock (no mods required) and it will give me the same fuel pickup as if I was using the standard pump (that is, I'm not going to have problems with having 1/4 tank of fuel or going around corners)? If so, then my mind is pretty much made up on the Walbro LOL Any idea if the Bosch can use the standard nissan sock or does the dimensions of it require me to modify the bracket to get it working? But if I mount it too low, won't I end up sucking up all the crap at the bottom of my tank?

Hey, I'm about to do my next round of mods to my manual S2 R33 GTS-t but after searching through various topics, I still have a few questions regarding replacing the stock fuel pump. My current mods are as follows: - Blitz turnflow front mount - Blitz Sus Power pod - JJR 3" dump/front pipe - 3" X-force high flow cat - Kakimoto 3.5" cat back Upcoming mods: - Greddy E-manage I'm chasing roughly 190-200rwkw (trying to stay at 10psi for the turbos sake) and long term plan includes a high flowed turbo (~240-250rwkw) and after reasearching, I'm tussling between a Bosch 040 and a Walbro 255lph pump because they are both within my budget. I played with the idea of a tomei or a nismo straight drop in pump, but decided to go with either the bosch or walbro. Now my questions are: 1) Between the bosch and walbro, which one is more "plug and play"? I want something that will drop in with little to no modifications and without too much messing around of the wires. 2) I hear about people having problems when running low fuel or taking corners with an aftermarket pump. I read that the Walbro drops in to more or less the stock position, cos I wouldn't have the low fuel/cornering problem. True? 3) What is this mod that I see in threads regarding about a constant power feed to the pump (12v mod r 14v mod or something like that)? 4) For my current power level goals of 190-200rwkw, will the stock fuel reg and injectors be sufficient? I'm sort of leaning towards the Walbro because alot of people say it slots in pretty easily, can handle the power I'm chasing now (and in future) and I won't have such problems with the engine cutting out due to cornering or low fuel. If anyone thinks what I've wrote is wrong, please enlighten me before I make a purchase on either of these pumps. Cheers.

BUMP!! Surely somebody must have one lying around or knows someone who does lol

Yeah it does seem like an earthing cable but I couldn't figure out what it's trying to earth lol no worries, I'll fix it tomorrow. Since you mention it, I've used 1m thick galvanised steel for my turbo heat shield, and one of the mounting points is using the same bolt as the above grounding cable (can see it in the pics). Is that going to be a problem?

Hey, just wondering what this wire/cable thing is, cos I was fabbing up a heatshield for the turbo when I noticed some of the wiring was frayed and coming loose (my guess is that it's going to pull apart in half with a bit more driving). It looks like it just bolts to one of the bolts on the manfold heatshield on one end, and the other has a plug which connects to the strut tower through just a bolt. Car in question is a S2 R33 GTS-t. Any idea what it is and if it breaks in half is it going to be a bad thing? http://img267.images...mg0013copy.jpg/ http://img577.images...mg0014copy.jpg/ http://img97.imagesh...mg0015copy.jpg/ Cheers.

BUMP!! Still looking for one Oh, and I'm located in VIC so I can drive to you to get it, otherwise I'm happy to pay for postage too

Hey, I'm just after a Blitz Sus Power Stainless Steel pod filter. I already have the adaptors and everything, just need the filter because my one has worn down and there's a hole in it In case you don't know what it is, it has a 6" neck and looks like this: http://www.alamomotorsports.com/blitz/blitz_sus_intake.jpg Price wise, the cheaper the better I guess hahaha as long as it's in good condition then it's alright Will pay cash or if you want, I have a spare HKS mushroom filter (genuine) if you wanna trade

I have to agree that there was a problem with the search function because I couldn't find anything about "reversion" when I searched, but typed into google "reversion r33 skyline" and voila, there the thread was lol

PROBLEM SOLVED!! :D:D The problem wasn't a boost leak or anything to do with the metal pipe. It was one of the hoses running from the solenoid (the vent to atmosphere one) which I tucked and folded out of the way when I was working on fitting the metal pipe. The way I folded and tucked it was enough to block air off so the e-boost wasn't getting the right readings and was reverting back to stock boost. So in a way, lachlanw was correct Thanks for everyone's help :thanks:

Any other ideas? I've double checked all hoses and clamps but still no good. I've even chucked the old Blitz pod back on but still not getting the 10psi I used to get By any chance, could doing the metal pipe intake mod (thread in my first post) affect my boost at all?

Alright then, no worries. Won't have access to a dyno for a couple of months though, so I guess I'll needa get someone to stand behind the car haha

Ohh ok then, that does give me some comfort knowing I'm not the only one with variance lol just that my variance hasnt been this big before though. Is there any other signs of telling of a boost leak? Reason being, I can't see behind me when I'm driving and my exhaust is too loud to hear anything AT ALL hahaha can just hear the turbo spooling over my exhaust if I'm lucky.

That's what I thought at first, but I have noticed on hot days I hit in the ballpark of low 9s but on colder nights (like last night), I would consistently hit 10psi (close thereof, sometimes 9.8-9.9) I was thinking about changing the settings on the boost controller but I want to check all avenues before I move on the settings as a last resort. Reason being I don't want to feed more boost into it just to compensate for a leak or whatever, so would rather find out whats the go before upping the settings on the controller. The Eboost solenoid runs 3 lines from the solenoid: - from the cold side of the intercooler piping (the one connecting to the crossover pipe just before throttle body) - from the wastegate - vents to atmosphere I'm not sure if it's closed loop, but I'll re-set it back to 10psi if all else fails

Hey, just got a small problem that hopefully someone can clarify for me. Car in question is a S2 R33 GTS-t. Previously, my car would hit max boost between 9.8 and 10psi (E-boost peak recall tells me so). However, after doing this mod: http://www.skylinesa...d__pid__5386208 I have noticed I'm only hitting 8psi max, and I'm not sure what could be wrong. I've tightened all hose clamps, intercooler pipes and checked every line that I have touched/removed from doing that mod but still can't figure why I'm only hitting 8psi. At first I thought there might be a leak somewhere, but the car idles perfectly and still drives more or less the same as before so I'm guessing a leak is out of the question. Unless there are other tell tale sgns of a boost leak I should be checking for? Settings for the boost controller are still the same and have been untouched. The only thing which I think may affect it is the change of my pod filter, as at the same time I did the above mod, I changed the 6"-inlet Blitz Sus stainless poddy to a brand new 3"-inlet DRIFT cotton poddy (hole in the blitz one ). Any ideas? Am I being too paranoid and its just a natural thing (eg. due to ambient air temp, humidity etc.) or is something amiss and I need to check? Cheers.
