What is the car used for?

If its just a daily driver then in all honesty neither are really required at all and you are just burning money for no reason.

Basically daily, but here and there i do go to the strip.. So just ditch these 2 mods u reckon?? So when is it become necessary to upgrade It to these mods??

Upgrade when the factory stuff isnt performing properly.

The stock radiator if in good condition will cope with the track work with the stock Turbo setup, and it will cope perfectly for drag racing. Your only on the throttle for up to 14 seconds:) .

I track mine alot, and everything is fine, with the stock radiator.

I did throw an oil cooler in mind you, because i was in the USA and pieced it together there. Worked out very cheap. I have upgraded to a GT30 recently, so will be keeping a close watch on temps next time to see how they look.

Strip as in drag strip?

Definately no need. You are only running for 13 seconds or so. You won't get enough heat into anything to be of concern.

Upgrade when you need.

When do you need? When your temps start getting hot. They shouldn't be with your current setup at all. If they are then a good radiator flush should fix it :)

If you start circuit racing or whatever then a oil cooler is mandatory. But for street driving, stock turbo etc. No need at all.

well i think at least get an oil cooler if you can afford it. can only give positive results.

dont they prolong the life of your oil?

Cheers... I know a lot of cars with mild mods , upgraded oil cooler, i guess it wont do anything bad.. Whats the ball park of an oil cooler this days?? And whats the common household name?

Mmmm, can also cause problems. I would only ever run an oil cooler with an inline thermostat. Lots of people run them without thermostats so it takes ages to get up to operating temperature, which increases motor wear and tear. So in my opinion, if you have a largely daily driven car using an oil cooler with no thermostat, you're doing more harm than good.

Any good Jap brand. Don't get Chinese. You're probably looking at $700 upwards for a new kit. Which is why if you don't really need it, don't waste the money on it.

You could also take a look at the Hel oil cooler kit which looks like some decent gear. Phil (PM-R33) did a group buy for these; though I doubt he will be doing another one based on how this one went: http://www.skylinesaustralia.com/forums/topic/357901-hel-thermostatic-oil-cooler-kit-group-buy/

Oil is the primary cooling system of the motor, I would upgrade this before the radiator and would run quality lubricants and coolant products before bothering to change the stock rad OR adding an oil cooler.

As stated already, you really need to consider whats necessary based on what you use the car for.

Cheers guys, as i stated before, my oil temp went up pretty quickly if i had 5-10 runs ... I just had my rad flushed.. Oil temp seems to be stable now... I have stock gauges except boost..is it worth changing my gauges too??Which only read boost , oil temp, battery voltage..

My water temps have been hitting about 89c(its happened twice only, on cool days and easy driving too). On average its 78 - 82C. Ill give her a flush and see how she goes otherwise Ill be upgrading my radiator soon. Bare in mind, I do have aftermarket everything on a stock motor.

As others have said, until it dies or can't do what it should, don't change it.

Defi gauges.... 600 for something a $50 gauge can do. I know what I'll be choosing. Ive got some Auto Platonium gauges. Payed like $200 for a complete set plus holder and all senders. All gauges seem accurate enough.

i bought a set of autometer guages. they are accurate and they are no where near as much as defi's and they work an absolute treat

No love for Defi's, they are so hot though :P

To compromise, I've got these:

Shadow Pro BF Series. I've got the smoked face (white illumination) on my A-Pillar and the white face (red illumination) in the triple gauge cluster. Read exactly the same as my tuners gauges so they are accurate enough for me. Not exactly cheap, just cheap compared to Defi's :P

The wonders of modern society - any stepper motor auto ranging gauge is as accurate as you could want and for $50-100 on ebay they are a bargain really. Defi are the pinnacle, but just too exe, you can buy 5 to 10 chinese ebay specials for the price of a Defi. And lately you can still do this and have the Defi name - yep, the china's have made defi copies/knock off's. Even the box they come in looks Defi.

      Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.

      Oil pan for RB25DET NEO Stagea "version"

      meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)

      I'd love a Haltech ECU, and Haltech 10 dash. Was having a chat with Rob and Andy @ Haltech when Rob put one in his MR2. First one I'm kind of interested in too, as you can dim it RIGHT down. Andy was saying bright dashes is one of his peeves too!
