Hey guys, i got a little bit of an issue. A few days back i decided to get my car mildly tuned (after some minor modifications) for 98 ron fuel and driveablitiy. Towards the end of the tune, the car was making much more power across the rev range however, the tuner stated it should be much higher provided the amount of boost the car was running. He then checked a few bits a pieces and then noticed the compressor wheel on the turbo was damaged, it had a few pieces missing and looked like it shaved a bit of the turbo housing.

So basically i need a new turbo, however this tune cost me 880 dollars, Seeing as the boost is adjusted via the solenoid, will getting the exact same second hand turbo throw this tune out the window?

If your swapping a stock turbo for another stock turbo, then it wont be too bad.... just not ideal. Of your running anything other than a stock turbo, then yes, your tune will need to be adjusted.

Will you be replacing with the same model turbo? A 'touch-up' tune should cost less than $200 to check for knock, AFR's and so on...

If it's an entirely different snail, then it might be debatable. $880 is steep though.

Yep. One of my mates is getting stung with the 'oh there was a foreseeable problem, but I didn't bother telling you. Come in for another tune for $700'

You'll need another tune if it was really down on power for the amount of boost he was putting in. Think about it... Once you put a new turbo on it will run lean.

Yea most like be the exact same turbo, only thing different would be the nozzle are going from 9.0t to 9.8t (seeing as i cant find 9.0t anywhere).

If its just an extra couple 100 for the tune up then ill probably do it asap, another 880 then ill just stick with my current setup =='

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      By Rezz · Posted

      Starting with issues 1 - 5, we have already run into a problem...!  Issue #4 contained 2x front brake calipers, instead of 1 caliper and 1x steering knuckle. Will have to call DeAgostini on Monday to sort it out. Anyway here's some photos.  Issue #1 is the front bumper, headlights and number plate. Issue #2 is the front wheel (with "We produced with spartan air." text on the centre cap!) and tyre, the front lip spoiler and cylinder head cover with ignition coils under the centre cover... which will never be seen again. Issue #3 is the bonnet and cylinder head. Issue #4 is the front strut, brake disc (with laser etched metal discs) and brake caliper. I stopped here because of the issue with the missing steering knuckle.  Next update will be #5 - #10 in a few weeks.

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      DeAgostini is one of a few companies that release quite large (the largest commonly available size actually) 1/8 scale models in a series of weekly issues over 100 - 110 instalments.  They release different models for different markets and DeAgostini Japan have release the BNR32 Skyline GT-R Nismo last month. I've made two of these 1/8 scale sized cars (one an R35 GT-R from 2012 - 2014, the other I'm just about halfway through, a BNR34 Skyline GT-R from the 2Fast 2Furious movie) so when this R32 was announced there was no way I could ignore it as it's my favourite out of all Nissans.  Each issue costs around $20 so it costs about $2.2K when completed. I suppose it is very expensive for what it is, but the quality and details are really very good, and there are many "gimmicks" like fully functioning exterior and interior lights operated with a remote control, working steering, all doors/bonnet/boot/fuel lid open and close, the side mirrors fold in and it even has a speaker for the engine revving sounds when you turn the lights on.  Each issue comes with a magazine that tells the story of the BNR32 Skyline GT-R Nismo from the first design stages of the BNR32 to Group A homologation and the various racing version that were run in the Japanese Group A and JGTC, and Australian Group A.  So I plan to update the build in this thread 5 issues at a time.  https://deagostini.jp/r32/?srsltid=AfmBOooKjxDc4EUK2rmXqMBPgyHfFJ24s4oEPJBNpnF-lFlsRoW0PE6P

      Help Understand GTT Boost Setup

      By joshuaho96 · Posted

      This would be a new pump with new gears. I'm just unclear on whether it's a good idea to run more oil pump flow if you don't actually need said flow. Oil level is set a minute or so after shutting off a warm engine so wouldn't the high RPM oil level in the sump end up lower all things equal? Plan is OEM clearances, main concern in my mind is whether the OEM pump can keep up with the flow requirements of any additional oil coolers.
