I agree with Cam, dump/front pipe, EMU and tune for 20psi on the stock turbo. As long as the oil restrictor doesnt get blocked it should last, mine did for over 4 months. Then save for the turbo rebuild...

(Aaron, I think 2.5mm would be better)

i was talking opening it up in general. mines open 2.5 if i remember right.

Alright. This is the smarts I like to hear. Anywhere that you guys can link me to more info on the oil restrictor? Dunc told me to do that too, so I'm guessing it should be at the top of the priority list.

iamhe77, ended up getting the black Aero kitted one from Wodonga.

Yeah, that and the dump/front pipe.

Is the Nismo the one with the two square tips? If so leave it. It is a damn good design and a lovely note :)

i dont think theres an exact write up. its the banjo bolt on the oil line from to the turbo

If memory serves, its actually the Nissan Sports Muffler - not the nismo one actually

Oh, if that's the case.... upgrade it.

2.5" exhausts have no place on our cars. Bang for buck is the Blitz NUR. Quiet as stock and free flowing 80mm pipe.

Yeah I'm just going by what I've been told. It's the one where you can press a button and it becomes quieter/louder. Not a twin tip.

Has anyone had an Emanage tuned in SA from here?

Yep, Nissan Sports Muffler. Its what I've got in my car.

No ones tuned with e-manage in SA yet; Ive got one sitting on my shelf for, Im slowly organising all my parts & funds to get that done at Willall

A good bet would be to take a road trip to melbourne to get an eManage tuned.... or get a group together and put Cihan (www.etuner.com.au) up for the night so he can tune a few while there ;)

I made over 200awkw on a 2.5 inch dump/front pipe mate, with the stock turbo... :whistling:

and here I was thinking that your initial 200kw was made with the Kamikazee turbo back that came with your car.

So if you had to start again, would you leave the 2.5" pipe on the car?

What are you guys basing the oil restrictor needing to be enlarged on? Has anyone measured the oil flow out of the turbo? Im assuming if its enlarged to much it will get too much flow and possibly blow the oil seals in the turbo. Im interested in this mod if it helps and if this is in fact a problem with the turbo.

I wouldn't have thought Nissan would run a smaller restrictor than needed.

What is the standard size of the restrictor? Is it easy to get that banjo bolt out while turbo still fitted in the car?

Cheers

So don't do it, no-one is forcing you.

Fact: Aaron blew up two turbos because his restrictor was blocked.

Fact: I ran 20psi on the stock turbo just to prove it wasn't going to crap its self or shear the ceramic off the shaft.

Nissan don't care what happens after the warranty has expired and cant be held responsible for sub-standard servicing or oil selection causing a build-up of crap on the inside of you engine. The stock restrictor is 1mm and obviously blocks very easily.

The front banjo bolt is the restrictor and can be removed with a little patience. The turbo seals are steel so I dont understand how you would think they will "blow out". Drilling it out is mandatory if upgrading to a bush core highflow btw. :thumbsup:

Take it easy mate, Im not attacking anyone here, just asking.

I read the link that Jetwreck supplied and noticed they are talking about a Garrett BB core. The guy was increasing the size of the restrictor when all Garrett BB cores have a restrictor built into the oil feed in the core. This makes it pointless to drill out the banjo for that turbo as Garrett have already set the flow needed.

If the standard turbo is high flowed with a new bush bearing core I can understand why you need to check the flow and adjust the restrictor to suit the manufacturers flow rates.

Just working out what circumstance it was advised in this thread to do it. If the turbo is stock I don't see the need. Just remove the banjo and clean.

Just gathering more info for myself cheers.gif

It's more of a safety issue.....a 1mm hole is a lot easier to block than a 2mm ect......cleaning it may not fix the problem as there may be more shit sitting around the engine that will block it at a latter stage(e.g. Aarons oil filter res)

I was told by my turbo builder to open up the hole as the Garrett BB set I have already has a restrictor in it.

BTW.

P.S. Chill pill guy's.....ffs the guy(radaladelaidian) was only asking a question about why we were doing it......there has been a lot of what I would call rude response's lately(I know I am one to speak!!blush.gif)......I know there are a lot of new guys coming on here now and maybe its the way they write responses but I am sure they did not wake up in the morning having the objective of pissing you off by the end of the day.....

well maybe Aaron and Iain wake up with that thought towards each other....I think it's just sexual tension though! :P

yeh i had an oil blockage near the pump. and it couldve been the reason it kept blowing. but ive fixed that since, and got more power after another tune.

i'd suggest doing it, but as scott says no ones forcing you, but your turbo

      Looks like they've been through a few versions of the kit; that is not the one I had trouble with (it had the level sender attached to baffles on the floor, the one you linked the level sender is hung from the hat). One obvious point about that kit is it has no baffles at all, not even the factory setup (although it looks like you can retain the factory setup if you want).  Not sure if that will be an issue or not, the good news is it looks like you can get the pump nice and low in the tank, but that doesn't help if the fuel is all sloshing to one side of a wide flat tank

      One more question if you don't mind. Is the first kit you tried the same one as they currently sell as their fuel-pump-hanger kit? https://frenchysperformancegarage.com/collections/fuel-system-kits/products/fpg-bnr32-fuel-pump-hanger-kit-single-fits-stagea-c34-nissan-skyline-gt-r-r32-fpg-087?variant=42131478315186 Because according to their video the low fuel warning thing can be taken from the OEM hanger and attached to their new hanger. Just wondering whether this is the kit you weren't happy with, or whether it's a different revision. Thanks again!

      That's the thing....the basics of fuel and ignition are deceptively simple.....getting it to behave like factory in all conditions after airflow mods is way more complex. Newer cars like the V37 are all about modifying the standard ECU which is about a billion times more complex than they were 20 years ago, with a bunch of parameters affecting others

      The larger TB I had on the SS was a pain to get to idle right, but, that was cable In the end they just raised the idle up a couple of hundred RPM so it was happy idling away either in gear or in park (slush box life) I'm curious on how my NC will idle with the new intake, larger TB, and cams that are currently going in/on, but I have faith that MX5 Mania will sort this "electronical" "black magic" out the best they can in the tune with a electronic TB Sometimes I wish I knew more about the intricacies of tuning, but most of the time I don't because I know it would hurt my brain 馃ぃ

      That's the thing. Cam is smaller than before.. though the old cam was +6 degrees advanced. We're talking huge changes here, the narrowbands want to trim out 20% of fuel and pull the (wideband) idle to like 16.0 AFR or such. One side is a little more trimmy than the other. Think along the lines of ~20% to ~15-18%. Unfortunately my scouring of the internet hasn't really found anyone with this issue. People either just disable NB's or have them wildly different, where one is -20% and the other is +20 or 0 (i.e a sensor is just dead/wiring is just busted). Turning them off and relying on the base map only results in the wideband reporting at about 14.0 with the Varex closed. It'd be a little leaner (closer to 14.7ish) with the Varex open. I know I can just change the switch points so that the narrowbands agree with the wideband, but it's still odd. Both of them are reading voltage, it's just that they're reading quite high mv, in the ~800 region. It's just odd. This was with the IAT fudged to report it was about ~22 degrees which is my guesstimation of the temperature in the room. I have an OEM sensor ready to try tonight, which is slow and crap - but .. worked last time I used it. Sadly I am aware that idle tuning with the big TB is going to be a PITA and I look 'forward' to many hours spent stalling or stumbling idle or delving into drivability things.
