TTT Posted May 31, 2012 Share Posted May 31, 2012 so was no restrictions.. just more boost and tune needed? Link to comment https://www.sau.com.au/forums/topic/58229-top-rb20-club-do-you-have-over-260rwkw/page/91/#findComment-6378765 Share on other sites More sharing options...
Roy Posted May 31, 2012 Share Posted May 31, 2012 Nothing was changed that would make a difference. It blew out the turbo to mani gasket mid tuning so that had to be replaced. The areas of concern still need to be looked at but with tuner busy before he goes on holidays we had to focus on the tuning and fiddly bits. So when I get it back this weekend I am going to redo all the piping with Wiggins clamps as once the undertrays and brake ducts etc go back on buggered if I will ever be able to get to a blown cooler hose Link to comment https://www.sau.com.au/forums/topic/58229-top-rb20-club-do-you-have-over-260rwkw/page/91/#findComment-6379268 Share on other sites More sharing options...
Roy Posted June 13, 2012 Share Posted June 13, 2012 Thought I would post the dyno run. Got Phillip island in 10 days, then play with trying to optimise boost with a controller. May throw the bigger turbo on to see if I cant get 330-340rwks out of the std RB20 I really have no idea how long its going to last at this boost and power, I was mega comfortable at 260-270 but I am kind of in uncharted waters here Link to comment https://www.sau.com.au/forums/topic/58229-top-rb20-club-do-you-have-over-260rwkw/page/91/#findComment-6398161 Share on other sites More sharing options...
SimonR32 Posted June 14, 2012 Share Posted June 14, 2012 That's big power Roy, even when I pushed my RB20 as hard as I could I didn't get that much Do you still have the standard RB20 box? God knows how that is holding up, I had a wack less power and managed to break a RB25 box In saying that I don't actually think you will have issues with reliability, pistons, rod and crank should be fine, E85 is the juice of Gods... The bearings may take a beating but who knows, time will tell.

Roy Posted June 14, 2012 Share Posted June 14, 2012 Yeh std 210,000km gearbox. I take it pretty easy with shifts and only run a spring centre puck Exedy clutch and only run top of the shelf Castrol gearbox fluid. I feel as though I am living on borrowed time at present with the engine and the box. It has served me well IF it goes the way of the Dodo. Hope not, would be funny if it hangs around for a little while longer and gets some improved track times to boot.

SimonR32 Posted June 14, 2012 Share Posted June 14, 2012 (edited) The motors just don't seem to die! I'm running the Castrol good stuff in my box at the moment but changing it out for some Redline shockproof because my syncros don't like keeping up all the time. People think Redlines shit for boxes but when it's likely to break sooner or later I really don't give a shit as long as it stops crunching haha Edited June 14, 2012 by SimonR32 Link to comment https://www.sau.com.au/forums/topic/58229-top-rb20-club-do-you-have-over-260rwkw/page/91/#findComment-6398947 Share on other sites More sharing options...
GTScotT Posted June 14, 2012 Share Posted June 14, 2012 lol the redline will stop the crunching, and take the syncros with it (from what I have seen) its an oil with abrasive qualities which end up deglazing your synchros and in theory keep everything in tip top form. On an old gearbox though it will generally strip away more than you want to. If you want to try deglaze the synchros before you give it a try, do this: with the motor on and car stopped hold the clutch on the verge of friction point (so it wont actually let you into gear) then try to select the gear you want to fix, as you firmly attempt to select the gear you will notice the revs drop (if they dont drop your not doing it right) only do it for 2 or 3 seconds at a time and i dont recommend doing it forever in a day. I got this from a high level gearbox fab guy, this trick fixed the box in my old Evo 4 to perfection.

Rolls Posted June 18, 2012 Share Posted June 18, 2012 Interesting, I thought that would just make the syncros worse, might try it in my next shitbox.

Wheezy Posted June 19, 2012 Share Posted June 19, 2012 (edited) It sounds like I need some injectors and some corn syrup. Luckily I'm about to move 10mins from a supply. But way further from my tuner. Roy, what are the specifics of the new injectors and the nismo pump if I may ask? I'm thinking my Bosch 023 would be better replaced by a stock fitting pump (ala nismo) and the injectors aren't upto the task anyway.

Roy Posted June 19, 2012 Share Posted June 19, 2012 Its just a Nismo in-tank pump. Injectors are something or others around 800cc I think and for giggles Nismo fuel pressure reg. Nothing exotic about the fuel system at all. I am reading some of this stuff may not be E85 compatible but meh...I am also running 95 on the street so system is getting regularly flushed Link to comment https://www.sau.com.au/forums/topic/58229-top-rb20-club-do-you-have-over-260rwkw/page/91/#findComment-6407104 Share on other sites More sharing options...
rx-line Posted July 12, 2014 Share Posted July 12, 2014 Anyone ever experience their rb20det running in and out of rich 10 afrs and then 12s switching back and forth? I am assuming it runs 10's on cold start up map but will it go rich when too hot as well? Or is it my fan drawing to much power. All of this was noted on idle.

rx-line Posted July 12, 2014 Share Posted July 12, 2014 Also experiencing it want to die after any amount of revving, vaccum related?

R_34 Posted July 12, 2014 Share Posted July 12, 2014 Vaccum leak would make it lean not rich. And you run very rich, on cold startup I have 12 and the engine enter close loop pretty quickly if the engine sees some lights revs/work. Blown fuel reg maybe. Clean you AAC valve for your dying symptom after some revving.

rx-line Posted July 13, 2014 Share Posted July 13, 2014 (edited) Plugs were fouled so I changed them with the bcpr6es and the idle surging/spiking to almost dieing went away. Cleaned iacv, and messed with the tps, set it too .5v closed and it 4.2v wot. Ordered a new maf. Has a small miss and still runs 10's in afrs while cold. For is set at 46psi not running and 36psi at idle with vacuum on. Not sure what the deal is.
