  1. what power did it make with the new turbo ?

    I havent got a dyno figure since the turbo was rebuilt and hiflowed.

    It was 204 KW at the wheels prior to the work, and going from seat of the pants feel, (and the speedo) there has been a decent jump in the top end.

  2. Well time has come to put old faithful up for sale.

    Its a 1998 R34 GT-T with the following features;

    • Apexi Power FC + Hand controller
    • Turbosmart e-Boost
    • Hiflowed Turbo

    • Grade pack
    • Climate control
    • Power mirrors / windows
    • Remote central locking
    • 2 way factory fitted sunroof

  3. For anyone who is intrested I had it rebuilt by hypergear and hiflowed.

    Seemed to be the best option for what I wanted to spend.

    Boost comes on a tad later, but does not feel laggey and now there is no dropoff after 4200 when running at 1bar so im happy with that tradeoff.

    Attached pics show what was stopped from flying out the exhaust by the cat.

  4. and since you have an Eboost you either need to have it set up properly or replace your wastegate, it should not be dropping off boost at 4200, maybe around 5500 with the restrictive exhaust housing but 4200 is too low.

    I was told by a few people the stock turbo being unable to maintain the higher boost (double stock) as the revs increased is to be expected, not an issue with the wastegate or Eboost. It seemed logical to me, but I guess that was just an assumption I made that suited the facts and backedup what others said, lol.

    When people say get a highflow thats what htey mean, rebuild stock turbo with bigger spec wheels. Hypergear, gcg, lots of places do it. Once again you need all the parts listed above if you go a bigger turbo though.

    Thanks.

    Am getting Hypergear to rebuild and highflow my turbo.

    It seems to be the better option when you take my requirements into account.

  5. but even something like a Hypergear bolt-on highflow (not one of their huge ones with custom housings) would be an excellent bang-for-buck upgrade. Should be able to get an easy 220-240rwkw out of the standard injectors, was only running 15psi through mine but it certainly made the 2t bus get up and boogy.

    In the end Ive decided to send by old turbo to hypergear to be rebuilt and highflowed.

    Seems to be the easiest and most cost effective option given that I dont want to change injecters, AFM, etc.

  6. You were running 15psi through the stock turbo?

    No wonder it shat itself... No more than 11-12psi should be run.

    Its been that for the last 8 years or so.

    And yes, hi-flowing will make it laggier, you are putting in larger wheels.

    Ok thanks, had never really thought about what hi-flowing entailed, I thought it was just porting and polishing or something like that.

    $350 is for second hand stock turbo.

    Realistically to put a decent hi-flow, ball bearing etc, $1600 is the cheapest you'll get. You can get bush bearing ones for around $800 but their performance is not as good and for 220rwkw there is little point in spending $800, then $500+ for the tune only to gain 20rwkw and more lag.

    I would not get a bush bearing one, may be me but I dont think they last as long.

    Hey, is it possible to get my turbo rebuilt? If so where?

  7. to solve your situation Ive got to say hypergear hiflow...

    Thanks
    stock turbo wins for economy though

    Considering the Ks I do thats a consideration. Is there any rule of thumb on differences in fuel use when highway cruising?

    i think he ment including turbo which sounds about right. honestly mate if you dont want to spend the bucks and happy with 200kw then buy a stock turbo and run 12 pound max and it should last

    From some of the info posted so far I may just end up doing that.

    I got about 8 years out of the old one with the boost wound up.

    Unigroup supply fit tune of a Nistune board.

    Cant just tune a stock ECU now can we? LOL need to buy the tunable bit :whistling:

    Guys, Im not running a stock board.

    I have a PFC fitted and am factoring a tune no matter what I end up doing.

  8. hypergear, your pretty much either limited to the smallest hi flow he has or a bigger one with less boost as your injectors, afm and fuel pump are going to be at there limit, i maxed my injectors and afm out at 230 rwkw but that was over tuning the afm and hitting 100% duty cycle on the injectors neither of which is recomended.

    I wouldant mind another 20 rwkw, as long as the difference between that and a stock item isant silly.

    GT2835 Pro S or Hypergear come to mind quickly.

    Thanks

    Hiflowed stock turbo such as the GCG hiflow are the only true bolt on turbos everything else requires more work to fit. There are no catches or hidden surprises if you bolt your rebuilt turbo back in the same spot.

    Never considered hiflowing the existing turbo.

    Of course that means I would have to have my current one rebuilt.

    Anyone have an idea on what it costs to have a turbo rebuilt and hiflowed?

    Also whats the downsides?

    Put a stock turbo back on there and setup the boost control better.

    There is no way the turbo should be falling over from 4200rpm for a start. That's just a poor setup.

    Interesting....

    Its not falling over as such, just boost drifting off as revs rise. I was told by several sources that is to be expected with a stock turbo when uppped to 1bar. (have attached dyno chart with boost if anyone wants to comment)

    And if you don't wanna upgrade fuel pump, AFM, injectors - forget upgrading the turbo. You can't do one, without the others.

    Was told by several sources I can upgrade slightly without doing the rest hence asking for advice in this thread.

    For my current use I would like some more power, but cant justify a large cost for a big jump.

    +1 on highflowing what you got.

    Bolt it back on retune it with some more boost maybe expect 230kw atw max id imagine

    Who would repair and hiflow a turbo?

    Yeah but so what?

    You get a turbo that will have all the lag, but no power because you are limited to 220-230rwkw (or so) due to needing ALL the other supporting modifications.

    Kando/hi-flow - all will go over 250rwkw with ease. No point having a bigger huffer for no gains.

    Cheap or not, its pointless when the OP has clearly stated he doesn't want spend anything more on any supporting mods when a stock turbo is $350.

    Also change the turbo = need a retune $$

    Ok, so hiflowing will make it laggy?

    I would not call an extra 20 to 30 rwkw no gain (depending on the cost above putting a stock one back on)

    While I dont want to get cought up in upgrading everything, I did factor a retune in, I assumed it would be necessary if I put a stock or different turbo back on.

    Thanks for all the opinions guys, they are apprecieated.

  9. Well the turbo on my R34GT-T has bit the dust and I need to get a replacement fairly quick.

    Rather than replace it with a stock turbo I was thinking of something with a little more performance, but Im not sure where what so I would apprecieate some advice. This car is my daily drive and I do a fair bit of open road crusing so I dont want anything that is laggy or peaky or sucks the juice down. So a bit more performance but not at the sake of useability.

    Current Specs

    - RB25 NEO DET

    - eBoost

    - FMIC

    - PowerFC

    - Pod

    - Hi flow exhaust

    - Spitfire coil packs

    What I want

    - Bolt on, no messing with makeing custom mounts or anything

    - Mild performance improvement (currently 200kw at the wheels)

    - Works with current mods, dont want to upgrade other bits like fuel pump, internals

    - Dont want it to use a lot more fuel

    - Dont run out of puff (old turbo started to loose boost from 4200)

    - Daily driver so not peaky or laggy. Smooth with boost over most of the range is good

    So guys, fire away with the suggestions!

  10. Pull the dump off and have a look at you turbine if there is one.

    If there is one. had to laugh at that.

    Will do that when I have some time on the weekend.

    Like mafia said check cooler piping.

    Had already had a look at the plumbing, could not see anything obvious.

    Don't drive it untill you find the problem if it is a blown turbo there will be bits of ceramic everywhere if some gets into the motor then hello rebuild.

    Ouch.

    I have already driven it over 300km (problem happend far from home).

    If the impeller breaks up can it actually make its way past the the FMIC? I would have thought it would have got stuck there?

    Also is it a rb34 strocker or did you mean r34? Guessing it's a rb25 neo.

    Doh!!!

    Yes its a R34 with a RB25. Silly slip there.

    Check list

    Check for split /popped silicone hoses

    Remove dump check turbo turbine wheel if gone remove turbo and manifold also cat converter

    If its neither of these drop the cat it may be blocked and will cause little or no boost

    These are my experiences in the past they may help otherwise I'm not sure

    Thanks, will run through the rest of these over the weekend.

  11. Just after peoples opinions on this.

    I was out driving yesterday and about 1/2 hour into the trip I tried to acellerate up a hill and noticed I had bugger all power.

    It feels like I have 1/3 or less the power that I normally have, it takes over 5 seconds to acellerate from 90 to 100 :blink:

    I didnt hear or feel anything happen, the motor still runs and idles smoothly but has bugger all power.

    The boost guages (factory and eBoost) both show vaccume but neither will rise above zero when under load.

    When the load / revs is in the area where it would normally produce boost it emits some white smoke. I guess this is cause its now running quite rich without the extra air?

    So my questions are, what can I look for that may indicate what the problem is? Does a blown turbo exhibit these symptoms?

    Could it be something else like the eBoost?

    Some basics

    - RB34 GT-T

    - FMIC

    - PowerFC

    - eBoost

  12. Evening all,

    I have a problem with my R34 GT-T where the TCS Off and SLIP lights are lit on occasions. The time between starting the motor and the lights coming on is varies, sometimes a couple of minutes, other times it may be an hour or more.

    Restarting the motor will turn those lights off for a random period again.

    My totally random guess is that its a sensor somewhere playing silly buggers (hope its not the PFC). Does that seem like a reasonable?

    If so, where and what should I look for?

    Is there anything I can do myself to see if I can fix it like clean sensors, or remove sensor wiring plugs and clean, check sensor cables for visable damage?

    Failing all that, who should I take the car to for this to be fixed? Nissan dealer, auto electrician or skyline specialist?

  13. **yawn**

    send a PM to r31nismoid he will luv to hear from you concerning that question....... lol whistling.gif

    or you could just save writing the PM and use the search function... or you could entertain me by posting up the reply you get from nismoid...

    Hmmm.....

    Did search first but didnt find anything.

    Tried again with less specific search terms (should not have had acrylic in there) and have now found what I was looking for.

  14. Hi Guys,

    I need to replace a couple of bits on my R34GTT.

    Second hand or new is fine by me.

    Or if any one knows of a store that socks these thats good too.

    • Headlight Housing Cover
    • Rubber bump stop - Boot
    • Trim Screws - Boot

    To make things a little more clear here are some pictures.

    Circled in red is where the missing cover should be.
