Bl4cK32 Posted April 7, 2005 Share Posted April 7, 2005 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 ) Link to comment https://www.sau.com.au/forums/topic/58229-top-rb20-club-do-you-have-over-260rwkw/page/16/#findComment-1288261 Share on other sites More sharing options...
Cubes Posted April 7, 2005 Share Posted April 7, 2005 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.

wizard2k Posted April 8, 2005 Share Posted April 8, 2005 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.

Roy Posted April 10, 2005 Share Posted April 10, 2005 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:) Link to comment https://www.sau.com.au/forums/topic/58229-top-rb20-club-do-you-have-over-260rwkw/page/16/#findComment-1291815 Share on other sites More sharing options...

Roy Posted April 10, 2005 Share Posted April 10, 2005 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:) Link to comment https://www.sau.com.au/forums/topic/58229-top-rb20-club-do-you-have-over-260rwkw/page/16/#findComment-1292025 Share on other sites More sharing options...
Wazz Posted April 10, 2005 Share Posted April 10, 2005 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 Link to comment https://www.sau.com.au/forums/topic/58229-top-rb20-club-do-you-have-over-260rwkw/page/16/#findComment-1292043 Share on other sites More sharing options...

I have to have a long hard think about what im going to do with the car. 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 Hey, if it works like that, you wont even need to borrow money to go on the holiday! 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! ???
