    yeah i have done it on my efr8374.. no issues.. sent it to OCD Works in the US.. locally i know hi spool industries do the mod as well

    Ive heard of OCD works. Hows the spool noise before and after? Feel free to PM links or videos if you want.

    Not saying you shouldn't go with the Borg Warner EFR stuff, however have you looked at Turbosmart turbos? They're pretty much a better version of Precision turbos.

     

    I've got a good mate that works for a reputable turbo company who says to stay away from them as theyve had a few turbos that came back with lots of issues. The other reason for sticking with EFR is that its just a drop in replacement. I was looking at the g45-1500 at cost price, but that would mean new down pipe, new lines, new intake piping etc etc.

    rb26, build year ? check my math

    I've never seen this on a factory built RB26 have the screws come out, or gears break for that fact. Only once someone has touched the motor have I heard / seen it.   I've seen a few factory built Rb25's shatter gears but we talking high mileage extreme beating at drift track, constant limiter for a full season.  Well outside what it was built for.

    Def happens. Happened to mine too. Have pics to prove. Super picky, I noticed the OP slowly dropping.

    Any help appreciated

    Has the VCT bulge on the intake(Actually, you can see the VCT solenoid on the intake side, so looks like an RB25, but thats not a RB26 intake for sure. Wouldn't be surprised if its a rb25 that someone has just 'slapped' on a turbo on the factory ecu.

    If its running like a dog, then the dead giveaway is the intake.. missing the AFM.

    Should you buy cheap Chinese tyres?

    in General Automotive Discussion

    Posted

    Personally, I would, but it depends. On my everday car like a swift or corolla, I dont mind, but def not on something that has a bit of power.

    I used cheap chinese tyres on my corolla for years.. no issues. Mind you its gutless. The quality of the stuff coming out of china, and the rest of the asian countries def is getting better.

    In saying that, the NZ Wiring CAS is an excellent upgrade too from stock.. lots of guys run them. Depends how much you want to fork out really and how hard youll be pushing your setup.

    Heres one as we speak! :D

    We must be related.

    I use a NZ Cam trigger kit with an ATI balancer. I needed to get a custom PS pulley to suit the RB25 PS pump from Hi Octane Racing.

    Motor hasn't exploded yet, makes 437kW, has seen half a dozen track days at SMSP, 2x silly wannabe Power cruise events and runs AC.

    WTB: EFR9280 with 1.45 housing

    Trying my luck here to see if anyone's willing to let go, or upgrading from, before I look at buying new.

    I have a mint condition EFR9180 w 1.05(powder coated compressor cover) too for sale or swap. Done less then maybe 3-4000ks.

    Personally I'd stick with ATI.. either 750 or 1000hp version, and stick a trigger kit too while youre at it. Lots of choices for trigger kits.. dont have to get PRP if you dont want to. Either way, wont get much change from 2knz. In saying that, the NZ Wiring CAS is an excellent upgrade too from stock.. lots of guys run them. Depends how much you want to fork out really and how hard youll be pushing your setup.

    R34 GTR Clutch Feels Like It Is Not Disengaging

    p.s. don't replace your clutch on the floor of your garage unless you have a great therapist  

    Me and me friend did this on his 33R in his basement carpark only using the torch from our phones. That top starter bolt musta taken us about an hour alone. Needless to say I am now an expert in removing R boxes in a basement carpark with iphone torch and limited number of tools :D

    Dyno Results for HKS GT III - SS Sports Turbo - Twins

    That HKS turbo (or a G42 1450) would give a massive hit to response but definitely a heap more headroom too. I guess you just got to decide how much "heaps more power" or keeping some degree of down low punch matter though I think that's come up before.   Realistically expect the ability to make 800+kw @ wheels but also 1000+rpm more lag too. 

    @DVS JEZ Ran a G42 1200 on his RB30 (so size down turbo from what you are asking about on the size down engine) and that even made big numbers, but also paints a picture of how much later spool will be.  Realistically probably not terrible for the power when you factor in the stroker, but if you're picturing something that drives like the 9180 then it's going to be pretty disappointing.

    Thanks lith. Wow thats hideous haha. under 150kw by 4 and 250 by 5. In comparison, I'm making 260 by 4, and 370 by 5.. and thats in 5th gear as well. From 4k the line is almost linear. Ive been looking at the 9280... Not sure if that will get me 4 digits either. 

    I'm so addicted to the response that I dont really want to lose it.

    RB Reimax Water Pumps - High Flow Designs - Anyone used them?

    So these pumps have been out for sale now for some years

     

    has anyone here used one and whats the comparison to an oem or even n1 unit ?

    I posted one a few replies up. Before I parked her up, I did lots of highway pulls. I def noticed that the ECT was alot more stable. Did lots pulls in high gears to redline and I was def happy. Safe to say my ECT issues were completely fixed.

    Which sequential? Do you know the ratios? Assuming your first will be super long as well, making it seem more laggy. Plus you're going to be running a massive turbo, and its a precision, so will be laggy as hell on the streets. Expect to be gapped by prius's. Precisions dont do compressor maps which kinda sucks.

    What work have you done to your head? Please make sure your engine builder degree's your cams!! We just played with the cams on mine and its alot more responsive and made a wee bit more power.

    Sorry mate I didn't see this. but issue is fixed, went to the local mechanic and turns out my regular mechanic that I visited multiple times didn't tighten the alternator enough. I went to double check and the tension now seems good, not overtight. Not sure how my mechanic missed that and said that it seemed all good to him lol.

    So you went to see him 3 times, and he couldnt tighten the belts..?!!?!? Time to find a new mechanic. :banana:

    Nothing seems to change when hot with mine.
    When you did the measurements for the build, is there enough gap (end-play)in the trans tailhousing to allow for any changes with heat/flex etc?

    They asked me to measure from the 2 flanges 3 times and average it out, thats all I know of.
