Get over it dude.

I edited the post to say *oops double post again* cost i f**ked up and posted twice.

I'm over it though, thanks for your support man. It was a tough time, big brother chick with fake titties was a struggle for the old concentration to stay on the forum.

thanks for taking the time to right all that hakai, your a legend mate, ill check that out as well :)

Um where abouts is the fuel filter on these things?

No problem at all :)

I have no idea where the fuel filter is, never changed one in a skyline so it'll be a first for me too. I'll do a bit of looking around tonight and see what I can find if I get time.

Good luck with the coils/plugs.

Just a note about taping the coils though, on my coils I noticed that the brace that bolts them to the coil rail is solid and runs around the entire pack, not like in that guide to taping them, those are R33 coils which I believe are a bit different, they only have screw holes at each corner or maybe that's just his?

Mine have the band running all the way around which makes it a bit tedious to tape the top and bottom, I haven't inspected the bottom of my packs since I taped them because I am too lazy to take them out, but literally one drive after taping them the heat seems to have melted the glue on the tape and the top part has just shrunk and pulled itself off the coilpacks. Not sure if this will happen on the underside, I'll find out when I get unlazy for a few minutes lol.

Good luck mate :)

Yep so you have experienced it clean up over 6k?

My experience wasn't the same, they simply crapped out and stayed crapped out big time. :laugh:

I have. The car would be shocking from about 3.5-4.5k and then pull to redline like you wouldn't beleive. I didn't think it was coils either, so i played with the tune and sometimes it would drive perfectly (usually only a quick fang up the street to get an af reading, followed shortly after by a quick test drive) and other times it was a bucket of crap (drive to work).

side note, mine does that. When i just start it it seems fine accelerating but once it warms up or ive been driving it a while it starts screwin it. Taking it to ultratune tonight, will pay for machine hire for diagnosis but thats about it. Anything spark related is to dam tiring to get to

thanks for the help and thx GTST for the diagram, your a legend.

Took it to a guy we know and he did an assessment for $60. Unfortunately this didnt include spark assessment but. he found fuel flow to be very low and pressure to be about a quarter of what it should be. Also my VAC was slightly low (no idea) and he thinks that when they replaced my timing belt they miss adjusted it by a gear. Also a possible MAF sensor fault.

What do you guys think? truthfulness, how much they would effect me, would they effect me in the way i described, is it still likely to be spark issues

ill try change the fuel filter (if it looks shoddy or clogged) tomorrow and see if that helps, otherwise if you guys reckon pump is a likely cause and that the guys not just being dodgey, ill probably just get a standard pump, as it should be sufficient to hold the 33 turbo im putting on soon.

thx

Edited by r32 gts-turbo

ok cool thanks dude, you think the standard pump is good enough? ive been seeing recond ones for about $120 i think ( or im tripping) and the gtr ones for $250 (tripping?) and although im upgrading turbo id be tempted to stick with the standard 1

Why do you suggest going with a 040 or 044? I was looking at the 040 and they go for about $230. A stock r32 one recond (or new?) is worth like $120 according to a mechanic or 2 i know and will be easily enough to run 14 psi on a 33 turbo with minor mods wouldnt it? From what i read the standard pumps are good for 300 bhp and id be getting like 220 max with those mods methinks

thx :(

Edited by r32 gts-turbo

Why would you bother going with another R32 pump or a recond one, when like you said for another $100 or so you can get a pump that is easily capable of handling that power, plus you know it won't crap out straight away, plus leaves room for more power upgrades in the future?

You may very well be able to support those mods and power from an R32 unit, but wy risk it? Better to go for a bit of overkill when it comes to fueling.

Completely up to you though, just what i'd do though.

FYI on ebay they range in price from $160 to $220 for a 040

Edited by insu

ohhh thats cheaper than i thought, saw the price of $230 in one of the trader pages on this forum, thx for all the research to :( Ill have a look at the walbro or the 040's on ebay. Im assuming the walbros and the 040's dont need any mod'ing to fit on, ive seen some pictures they look easy enough, assuming you dont need ecu retuned to cope with it (maybe a reset) or a new fuel pressur regulator? Just cut some crap off the mounting brackets right? Alot of people seem to be having problems with the walbro's leaning out so ill avoid them and go the 040, what model number should i look at? all 040's are the same? can you get a Aftermarket mounting kit for 040's?

Edited by r32 gts-turbo

You'll find that the problem with the walbro's seem to be that they are designed to flow their max amount at a voltage higher than that of the standard wiring loom.

If you sort that problem out, they should be good.

There isn't really that much you have to do to get them to fit, but you will need to do things like, replace the pick-up sleeve, lines from the sleeve to the pump, wiring, making the unit fit the bracket properly etc.

Alot of people seem to disregard the ecu controlled downstep in voltage on idle to reduce the amount of flow the pumps produce when idling, and just wire the pump straight in.

Check it out man, search button's you friend!: http://www.skylinesaustralia.com/forums/in...=67683&hl=bosch

hey ive already had a look at the diy on self installation and a couple of other topics on pumps, sucks that so much changing is needed i guess ill go with one of the tomei ones that doesnt require any editing

Edited by r32 gts-turbo

just thought id update this because it might be helpful to some one some where. Mechanic had a look told me i had bad flow bad pressure, so i replaced the filter and got him to chuck a walbro in for me ($300 all up, with a crazy pump price). Car is a helluva lot faster than it has ever been, even before the misfiring, when i had it running 12 psi. It has absolutely no splutters or anything like that, even droping it into 2nd from 1st @7k rpm nothing. Really rams u into your seat accelerating in 2nd (never had it happen before) and had absolutely no flat spot or power loss all the way to 6.2k, it kept moving didnt slow up at all like lots of people say happens rb20's, due to the turboes capabilities. So yeh my cars finally working and its maddd :(

Edit - 2 weeks later problem is back hehe

Edited by r32 gts-turbo
  • 3 weeks later...

Really? Is the problem back?

I have had similar problems, and were initially solved by splitfire coil packs however, the flat spot is still occuring between certain revs and am in the process this week of installing a walbro pump. Ive been advised by a few mechanics that this will cure it!!

Dont tell me otherwise, hahaha

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
