Troy, Sky30 is using rb20det tomei cams i believe in his rb25de head, so id say they are interchangeable. (10.25 cams require slight mods for clearance)

From what i understand as well (it aint much..lol) increasig the lift extends the power band as well.....so wouldnt this shift the redline on the rb20 up as well? You may make more power, but it may require revving it more to get more?......am i far off?..LOL

greater duration increases torque, lift shifts the redline up.....or am i wrong again ;) (all in the process of learning i spose :))

My fiddlings with the Engine Dyno sim tell me the increased lift increases power over the current power curve, increased duration is what shifts the powerband  higher in the rev range.

Yeh, thats mt limited understanding...thats why i like the idea of only 260deg, but the much higher lift.

i just thought that i would post this up here as these parts are perfict for your RB20 power up, i have a HKS GT2535, GTR injectors and GTR fuel pump for sale. I want $1300 for the lot. All is in good working condition as i have just been making 240.6rwkw with these pieces (and a few other things)

I just thought i would let the other RB20 owners know this stuff is avaliable from me. This is a reasonable price.

As for my car just waiting on the fitment of the new injectors then its off to be tuned and i have my fingers crossed for some good numbers.

wish i had $1300 im in newy aswell so id pickup.

Alright, time for this weeks update:)

First track day with 18psi and about 235rwkws today:thumbsup: In the morning it was 36 according to the climate control, water temps saw a max of 102deg C adn the car still didnt miss a beat, shame the same cant be said about the driver. Credit to the tune in this thing, 36 degree ambient temps, high water temps and the car didnt ping, didnt miss a beat, it didnt even feel noticeably down on power , it pulled / drove really well.

Did 1 x 20min practice session where i took it pretty easy as i had never been to Sandown before. Then did 5 sessions of warm up, 4 sprint laps and a cool down lap. Car didnt miss a beat, and in the wet session proved to be a barrel of laughs, i was driving around the track giggling, it was so much fun trying to get out of the corners...i must have looked like the village idiot as i was walking around the pits with the cheasiest grin ever.

I dont think i will be able to sell this car, perhaps ill borrow some coin to top of the coffers for my holiday:)

Engine Oil: Castrol Formula R10W60

Engine Coolant: Tectaloy 100 Plus

Diff: Castrol SAF-XA, 80w-140

Gearbox: Castrol Syntrax 75W/90

And im running a 19 row Serck oil cooler in driver side gueard, ducting / airflow could be improved as the cooler piping sit about 6 inches in front of it

...and im in Adelaide Wed/Thu/Fri. I have to show you the vid from today, its only a cheap camera so the brightness thru the screen caused a few focus problems, but you still get an idea of the grunt its now got and how well it hooks up:)

thats great news that i all held together on a hot day like today with 102deg water temps and no pinging :P

I know where i'm going for my next tune :P

were you not worried about the coolant boiling over? i would be considering a upgrade radiator at these temps...pwr make a good ones.

Yeh, i could do two laps and the water temps would creep into the low 90s, at which point i normally back off for a slow lap, but in one instance i kept into it for 3 laps and the temps just kept rising, all the way to 103de C:(

... if on a cooler day i had similar temp probs then yeh, but i put it down to the fact that today was as stinker, followed by torrential showers...ah Melbourne weather:) Plus i dont want to go to the expense of a radiator, if i keep the car ill get one for sure:)

i was running 1bar, the engine can handle alot more but i just like to play it safe. As for the running the strokeretc hense "(and a few other things)" lol. But as an upgrade these three things should be able to get any standard RB20 producing reasonable numbers.

Hey i was just wondering if you could possible give out some info on wat you used for your stroker.. and wat it got taken out to and so so.. also wat it performs like (obviously pritty bloody good cause its a rb20) but yer i'd like to do this to my rb20

I can see whats going to happen. Your going to keep the car, and cut the holiday short as your going to start missing the car too much and hooning around at the track in it, and come home :P

Hey, if it works like that, you wont even need to borrow money to go on the holiday! :(:D

Otherwise, feel free to bring it to Brisbane for me, and I shall lease/hire it off you for $1 a day until your return ;) How does THAT sound for a deal! I'll even throw in a roll of carpet or a half pallet of tiles for ya on your return! :D

WAZZ, the kit comprises of a Tomi poston and ring set and GTR crank and rods. at least this is what i have been told, it was like that when it came from japan but so far everything i have pulled off the car is what is said to be on it.

      Stock rb25det neo questions

      By Wazmond · Posted

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      By 25RBGT · Posted

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
