Hi folks.

I have just got myself a really clean low millage r33 gts-t manual

I always change all the fluid when I buy a car and use synthetic where possible.

I have been reading through catrol/nulon sites etc and have written down the recommended syn oils for the engine, gearbox which I will buy this weekend.

The confussing thing is the diff. I know these are an LSD and they are bolted into a performance car which screams for synthetic LSD oil..

however all the websites recommend a non LSD mineral oil around the 75W-90 range...

what are peoples thoughts on this? should I not be using an LSD oil? and why not recommend a mineral?

I was thinking a 85W90 full synthetic LSD oil?

really keen to get peoples insite on this

thanks!

the skylines aren't so much a "performance car". more a sporty family car. and also what the sites recommend as the oil would be based off what nissan originally specified. if you look into what engine oil is recommended you will find that a base mineral oil is probably all that is recommended as well. this doesn't mean that you have to stick with mineral oil. you can go synthetic if you want.

I've used Castrol SAF-XA 80-90 for the rear diff , if you have a look in the stickys in maintenance or do a search you will find plenty of info on diff oils.

      C-red tuning?

      Seemed to be good when Jeff owned it but they did a shit job on my car, probably worth a think before spending 10's of thousands of dollars where they might be cutting corners

      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

      By Rezz · Posted

      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
