Have you had a chance to measure temps yet Hayden?

Considering doing this and trying to work out if the size you've picked is big enough, and if it's not where to fit something bigger :unsure:

I'm halfway through fitting up the temp gauge, so I should have some info soon (finding time is the problem unfortunately)

One temperature variation I have noticed is the outside ambient temperature display in the dash...

After the car's been driven & parked for a short time, the outside temperature shows high 30's or low 40's thanks to the temp sensor sitting directly above the oil cooler core. :O

I'll get around to relocating it one day.

My oil sits around 87-90 degrees, and the water 76-80 on the freeway with the Nismo thermostat. That is with a 30 row 12an oil cooler. I guess the Greddy oil thermostat is set a little high. I wonder if the water-oil cooler is affecting it's operation...

I have still seen 118 degree oil temps at PI, even though the oil cooler has a 14 inch thermo running flat out. You can never have enough cooling at the track as I found out.

Great story. Was quite entertained!

Hows it go; Greedy pays twice!

AND

You get what you pay for!

Made in YumCha not so good, not so love you long time....lol...

Well done on sorting it all out in the end.

Years ago I was told that cooling the oil is more efficient than a radiator at keeping an engine from cooking. I never believed it till I put one on a V8 with chronic overheating issues. The core was approx 200 x 300mm (sold by a truck spare parts place to "cool a Mack" - I lol'd at him). So put it in & it instantly fixed my overheating problem. In fact I reckon I could've run without coolant, except I wanted the heater to work. Had to block the airflow (to the cooler) in winter so the engine had a chance to get to operating temp.

The one Hayden chose looks plenty big enough to me.

Edit: to clarify, mine didn't have a thermostat. That would've been a better idea, but meh, cardboard worked ok.

Cheers Hayden. Be good to see how it goes.

Where did you mount it mate? Got a photo?

No I don't, but I also don't have cooling issues, yet. If there was such a thing as a finned sump, it would probably provide all the extra cooling a modified road car would need. (Not talking track days here.)

Is there room somewhere out of the front airstream to mount a cooler? That would radiate a fair amount of heat by itself, or a small fan (or 2) could help (thinking computer case sized). I don't think there's room in front of the radiator in my car either, so one day could have to look for alternatives.

Anyone else noticing a slight handling change everytime they add more weight ahead of the front axles?

Nah thats cool Craig. I'll pull the bumper off when I get back and see what's what.

Tells me we only need a little one, which should be easier to mount. Say a 10-13 row. Just Jap have some really good pricing on the ones that Hayden used here, and there are some decent adaptors on ebay. Should be able to get something half decent for ~$150 plus hoses.

Look for a sandwich plate that allows you to angle the lines to/from it at 45deg like the Greddy ones.

Try to buy one similar to this: http://bit.ly/TJfXJw

If the adapter is one that only has the inlet/outlet coming out at 90deg to the filter, chances are you'll foul the hoses on something like the aircon lines...

You can get the grex thermo plate with a the two sensor bolts for about $140 delivered from the US. Scott has the details. Or do what I did and wait for a good deal to pop up. I think there is a hks cooler with sandwich plate for a pm35(same thing) on IM ATM......works out to be about $450 delivered.

I'll check out the US deal Craig, thanks. The one Hayden linked to looks like it'll be fine too.

GCG have them locally, but a bit pricier: http://gcg.com.au/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=1132&category_id=201&option=com_virtuemart&Itemid=101

      RB25DET with solid lifters - which cams ?

      They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required.

      RB25DET with solid lifters - which cams ?

      By GTSBoy · Posted

      I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.

      RB25DET with solid lifters - which cams ?

      By TurboTapin · Posted

      I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something?

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states that I need the Tomei solid buckets, solid lifter cams and upgraded springs.
