Nice curve. Do they make them for men?

Picked the car up yesterday. Unfortunately I wasn't able to drive it due to a leaky brake line I grabbed from wreckers as a temporary measure. Dyno chart shows normal tune (032) and against the fina

In all it's glory - following for AC's 1:25 then my creative line through 1

bout bloody time you overtook that pesky R31 Paul :P

Great onboard footage and nice driving mate :thumbsup:

PS your Nismo tachometer is disconnected because your using other means to track your speed aside from the electronic tachometer displayed?

Yeah the speedo cable broke recently so in the process of getting another one. Hopefully cable isn't too hard to R&R, but I am guessing it will be...

im not sure on that one Paul but I can't imagine it being as much as a PITA to change compared to changing / replacing a clutch and gearbox

Hehe nah all good Ant's, I only push the braking markers where I have run off, pretty much T1 only at Sandown. Always able to wash off enough speed.

Tyres were too hot after a couple of faster laps and just didn't want to turn in, so I decided to straighten up and was going quite slow once I actually left the track. Brakes are unpredictable too with the ABS unit in there, really inconsistent so once I sort that.

Sandown yesterday, cracked into the 19's. Can certainly see more time in there too which is good - particularly around the sweeper (and fixing the ABS issues!).

Put some high density foam around the radiator which works a treat, big difference. Could keep going for the entire session with water temps not getting any higher than 90c and good oil temps. Going to get trackart / Andrew to make up some proper alloy ducting and it should be good all year round. So I am happy with the oil cooler sitting in the radiator end tank - seems like a good solution and easy / tidy from a packaging perspective.

very nice Paul

Was the radiator moving around before the foam was installed causing the increase in water temps?

Nah just air escaping around the sides and top and not passing through the radiator. More is now forced through the radiator. Can definitely improve further with some proper alloy ducting, would probably just want to knock another 5 or so degrees off max water temp, oil was happy around 100-110c. The ducting would bring both down a touch.

Paul, sub 1.20s is getting quick. Well done. Be interested so see the rad set up you're considering as track temps are always an issue...Maybe let me know when you're down at Trackart next as I've got to go there too?

Cheers.

Cheers. Got a touch more weight I can take out here and there. Compliance intrusion bars being an obvious one, could also do carbon / glass boot lid and wing. Don't need the passenger seat & mount either.

Hence why I reckon an 18 would be achievable with a few tweaks. Can see time in my driving as well, but you know... always good to leave a bit of fat make sure you bring it home in one piece!

There would be some easy time had in moving away from the stock diffs and modifying the transfer case but happy to get there on a standard drive line from the gearbox on for now.

For sure will let you know re: track art.

did u retain factory power steering? I am looking at a EPAS electric kit for my build.....any thoughts?

Do u find the steering really heavy when tracking the car and the front wheel drive is engaged. Almost to the point of being exhausting after five or six laps at pi?

Thinking the epas kit will strip a fair bit of weight and maybe give me a better overall steering package? What do you recon?

Yeah steering is quite heavy - still factory, I think because of messing with the HICAS it no longer lightens up at lower speed. It also seems a bit variable - seems to get quite heavy for no obvious reason.

Just watched an EPAS vid would be a nice solution for sure. Could definitely cut down some weight there getting rid of the reservoir & pump etc.

And yeah itching to have a crack at PI with it, will be good fun!

Yes mine get heavy for no apparant reason. Some times it is like u have to wrestle the car at PI.

I am definately going to do something funky. At the very least an mr2 electric hydraulic pump plumbed into the system.

Maybe a full electric servo system like epas. This looks to require a whole new manual rack though.

      RB25DET with solid lifters - which cams ?

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

      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.

      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.
