Hey guys i was reading through threads about aftermarket radiators and was thinking of getting one before summer hit as my system needs a flush anyways and the cooling pro ones are nice and cheap. But it doesn't seem there are any for auto cars with a cooler in the radiator for the auto tranny, so i wanna know if anyone has one (i think the r33/34 one is direct fit from memory) and you are running your car without it and just you the front mount tranny cooler (upgraded obviously) bypassing the one in the radiator.

Thanks for any help, i have two weeks off work coming up so i planning heaps of maintainence/mods in that time and this is one of them.

just if it's cool to bypass it and just run an upgraded front mount kind of cool inplace of the crap factory front mount oil cooler. will it cause damage etc. I see the radiator one as more assisting with warm up anyway rather than cooling, i was just wonding if other people are already doing this without problems.

There is a noticeable difference with getting the trans up to operating temp... during a Melbourne winter (re: F**king cold).

As such, I would like to get my OE one put into my radiator, but cooling wise, I think you would need more than just 1 trans cooler if you deleted the in-tank one... especially for a Perth summer.

Go to supa cheap and buy the Davies Craig trans cooler, which comes with all lines etc.... Pull off the Davies Craig sticker, and voila! You'll find it's a PWR unit for HEAPS cheaper than PWR sell it for... Just helped GreenGhost fit one to his Stagea: heaps better than the factory (RB25NEO) one...

S1 Stagea has auto fluid going through the radiator and then through a tiny little bar cooler. If you are going to upgrade the radiator you should get one (they are available) with the connections for the auto trans fluid. Running two aftermarket trans coolers will not do the same job as the radiator initially helps bring the auto trans up to operating temperature more quickly and statistically the majority of trips are short ones.

I replaced my radiator with a thicker one with the auto trans still running through it and got the largest (V8) Davies Craig (Supercheap) trans cooler as well.

I won't be much help to you being in NZ because I didn't buy a Japanese racing radiator but just got a generic National Radiators unit from my local repair shop for about $150 (he just looks in the catalogue for one with the same dimensions only thicker and with the auto fluid and rad hoses connections in the right place).

now thats not a bad idea, the other thing i was thinking of was it cant be that hard to add a pipe running through the bottom tank of an aftermarket one, might cost a couple of hundred bucks but would be well worth it. what does everyone else think?

i emailed PWR they do one for an auto R33 would be direct fit, comes to $990 delivered, pretty steep for a street car so i think ill be steering clear of this one although im sure the quality would be awsome.

$990 OUCH.

However, working by that logic a R33 auto radiator will fit??? That means there are lots more options; and there are group buys open on SAU from time to time as well.

      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

      Help Understand GTT Boost Setup

      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.
