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.

      RB20DET lean on cold start

      By MidnightR32 · Posted

      Ah, fair enough. For the IAT, I'm using a legit GM sensor that was used on the car prior to my current build. I'll get another wideband and IAT ordered and follow up when they show up. Thanks for the help.

      You shouldn't need to massively fatten up the mixtures for cold conditions. For one thing - 0°C is not that cold. For another, the Haltech will be using the IAT sensor to tell it how dense the air air, and calculate the correct amount of fuelling. Then the cold start enrichment is added as a % on top of that, so it should scale with the main fuelling. You might also doubt the IAT sensor at this time. You're not using one from an RB26 are you? Using a nice Bosch sensor or similar? Happens. Some wideband units take great pleasure in killing their sensors. Put another wideband in the tailpipe and compare. Or just swap the sensor to a brand new one and see.

      Oh, my misunderstand. When the car was running, it sounded ok, but if I gave it any gas it wanted to die but caught itself afterwards. It's very different from how it was a couple months ago when it was warmer outside. The logs show that the AFRs are better during, what I assume, is warmup enrichment. Because it's cold, and air is more dense, should I work on the enrichment bit?

      Rb20e and RB20DET parts

      By A31Skyline · Posted

      yess of course im not using 2nd hand parts from my spare engine, but the place where i live is hard to find parts for the RB20DET ,but for the RB20E is everywhere including new ones and a lot cheaper ,because for the RB20DET you have to order it overseas to get one and it cost a lot of money 3x the price to be exact. so i ask this topic because if i can use the new ones but for RB20E is it compatible or not. if not im screwed haha, not totally screwed but i have to save a lot of money first before i can begin repairing my engine, thanks for the information before.

      Unless my sensor just died, was only a couple months old, I strongly believe it didn't. How can I test it? I never mentioned it being 20:1+?
