Mine is gtt r34 with 500 bhp looking to boost up to 650 as it is forge so think having heavy might not be that bad at the end due to power.

 

just worried it won’t shift in cold morning

It's not just the horsepower figure, it's the torque and drivetrain. You may be able to get away with lightweight, try it first and see if it grinds at all.

If the synchros are on the way out some lightweight shockproof will help but only delay the inevitable. Don't shift quickly, double-clutch your downshifts. You will be able to get a bit more out of the transmission before rebuild. Don't try to DIY a transmission rebuild unless you feel like taking the transmission out multiple times. You will save a lot of money if you're willing and able to drop the transmission yourself, that's a good chunk of change right there.

It's been 8 years now, ~80000km, and no change in shift quality on my box from the first time it managed to change gears with smurf's blood in it.

i take it your box was worn so it won't shift and redline brought it back ?

Yes. I bought it for Neo my engine conversion and it changed gears nicely when not spinning, but would not while the engine ran. Changed to lightweight and it would change gears straight away.

new refurb one is around £1300 and want to kill this, buy one next year and then swap.

I can never understand the "kill this" mentality. I bet you I could happily drive your gearbox for the next 10 years.

      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.
