well it has a 'decent' twin scroll on it now we hope. though really twin turbos are the ultimate twin scroll set-up! can't get a more divided hosuing than that and the firing order on a RB26 lends itself to twin parallel turbos very well. tuning will have to be completed bloody soon as WTAC is in a scant 2 weeks!!!

a few reasons. one I really wanted to try the new EFR gear so I pushed hard for that avenue and came to an arrangement with Borg Warner. We have been very happy with twins on that car and their performance was unquestionable. The downside was weight and packaging constraints. even on a full house race car removing and replacing a standard style twin turbo set-up is many hours work. a single turbo set-up with v-band can have the turbo off in minutes and the whole lot in maybe an hour or so. Another reason was quest for a bit more power and also hopefully smooth out the transition onto boost as the midrange was pretty savage with twins to the point where we thought traction might benefit from a slightly smooth curve. the 9180 flows 96lb/min which is more than the -10s could supply. yet another reason was simplicity of piping and plumbing which again saves time in remove/replace and also saves some weight.

nismoid. that test is a bit off. no way does a nismo pump flow the same as a stock GTR pump..... they flow 276l/ph stock around 200 and bosch 044 around 230.

nice one mate. 1:06 for a first test day is pretty rapid. should be very quick once dialled in. looks bloody quick for 270kw too. they must be real kw not the inflated kw everyone talks about... hope it goes well for you at WTAC.

yep, driftt is the one to talk to. knows importing and local to perth. the basic mods you describe wont be any hurdle. and yes you can import it and not register it for as long as you want.

holy crap PJ!!! that is awesome mate. love that it's not super loud either. would love to see the specs? even a basic outline? great stuff mate.

yeah it's definitely true that results are often the sum of their parts. this car with the 9180 (no real secret I'm talking about the Advan/Hi-Octane RGM R34) is a maximum effort car so has the best gear where possible. nicely built RB30/26, ARC intercooler, hypertune plenum, full race manifold, twin turbo-smart gates, EFR 9180, beautifully made piping, hollinger, dry sump, autronic ecu and CDI etc etc. so if ever a 9180 is going to be pushed it will be on a car like this. we have very high hopes.

bingo. they are a VG30 sensor in a RB26 housing. the airflow vs voltage curve is slightly different to a VG30 AFM but not significantly so. I'm sure it can be dealt with in nistune.

I reckon it's all the twin retarders marlin..... or perhaps just twin retards? either way. top read.

I'll tune it troy with my dividing rod and geiger counter. just buy me 10 pints before we start. so what's up with the boost control? don't tell me you've gone soft and want to turn it down?

yeah I agree. $25-$30K is the more realistic budget for a really nice GTR. but I still think it's worth doing. sell your car for $10K, then you just need $15-$20K to get yourself into a really neat lightly modded GTR. better brakes, better driveline, better interior, better wheels, better bodywork, better resale, better engine, better diff, do I need to go on???

hmm, my advice. save a bit more cash and then do the following: by second hand 3inch (or bigger) turbo back exhaust (or if you have catback just the bits you need). you can get good used gear pretty cheap. get a front mount. again, if you go used you can get one nice and cheap. even better you might be able to score a used blitz or other jap brand cooler used for the same price as a new china one ($500 or so). add a high flow panel filter to the airbox (K+N are very good and last forever) or if you want get a pod (if fitting a pod get a alloy intake pipe made up at the same time). edit: just saw you have a pod, ok just add the metal intake pipe. the manual boost controller is fine for this level. once you have the full exhaust and the FMIC it's time to get it tuned. either get a nistune or get a used power FC. unfortunately R33 power FCs can be pricey so in your case nistune is probably the way to go. all up to buy the nistune and have it fitted and tuned should be around or just under $1000. the used exhaust and high flow cat less than $500 alloy intake pipe $200 used jap front mount in good nick $500 (or china kit $350) The other big thing is tyres. no use having 180rwkw if you're on linglings. save up some dough and get some good tyres. you can get a full set of dunlop Z1* for under $1,000 from tirerack in the US. they will turn that wheelspin into forward motion and give you a good edge on your mate. I'd say all of that including tyres will be under $3K. and possibly as low as $2500 if you do it slow and hunt out some real bargains.

Yeah I don't have anything really bad to say about 6boost manifolds. they are a great product. I have recommended them to friends of mine as far back as 5 years ago (or more). I can't say I've tested the same turbo back to back on the same car with a full race vs a 6boost. maybe one day. but I have looked carefully at both. They are both great products but I personally feel the full race is a little more advanced. they are so nicely finished too.

yes serious about considering a bigger turbo. but we are not nearly finished with this one yet. like TheKeeper said we have not really stretched the legs on this one yet and the thought was pretty much like you said. it's response was so much better than expected that we'd be willing to sacrifice some of that for even more top end. but we'll have to see how much top end it has yet... if it makes a power number that is in kw at the wheels and starts with a 6 then we'll probably be satisfied. the biggest thing the 9180 response has done for me is make me even more excited about the twin 6258s. they sit between a single 8374 and a 9180 in terms of flow (88lb/min combined). my thinking now is they'll probably be at least as responsive as -5s (maybe even -7s/GTSS?) and should outperform -10s up top. to early to stake my life on such predictions yet but it no longer seems impossible.

yep there will be graphs I'm sure. we have agreed to provide the graphs to Borg Warner and Full Race and I'm sure they will want to share them. I don't know if the scale will be intact but I don't see why not. A certain power figure at just 1 point in time one 1 dyno doesn't really give the game away....

cool. that makes sense. I know the cores are super light, it's the fluid inside them that's heavy! and yeah I know with bodywork on and proper ducting frontal area as presented to the airflow is much reduced. I still think you'll find you just don't need that much cooling. having said that I'm sure the guys are on top of things and have done their sums. either way can't wait to see it. time is ticking away!!

I'd like to see a garden hose that can flow as much as that top fuel set-up! lol, more like a fire hose! even at idle it's crazy. no wonder they have 6ft flames out the headers....

they are big cams. exact spec doesn't matter too much. I would suggest something around 280 10.5mm if it's a track car. the thing is lots of the jap cams are a bit too big on duration and too small on lift to enable them to be bolt in cams. honestly the way it's looking it would be an ok turbo on a 26. with the 8374 on your RB30 you might find you want something bigger, though for a road car it should be fantastic.

nice mate. I must say I'm a bit shocked by the size of the coolers!! will be a fair bit of weight up front. is it really necessary to have that much core? for a big power street car I could see it but for a track car that really seems like a lot. love the custom front end etc though.

you're kidding right? even ths original dunlops (and the bridgestones for that matter) were miles quicker on a track than 19inch R888s. the new SII dunlops will be faster again. R888s on a R35 is not a happy combo. you will go slower on them than on the standard run-flats. unless somethings changed since I tried them in 2008?

yeah like duncan said. I personally would replace it. you've done everything humanly possible and as flow goes cooler to filter you should be fine (most systems go filter then cooler though so double check that?) but it's a big risk. there must be a better option for replacement. we are probably all being a bit over cautious especially given the nature of your failure but I can't help but think if it were my car, i'd keep hunting out that replacement....

S3 have a much deeper front lip. they have dual airbags, they have the red stiching, they have projector headlights, they have the improved gearbox etc. they are almost all 1998 models. some 1997. 1995 is 100% series 1. no doubt about it. the holes in the front bar are a popular option. some people fitted them, some didn't. they don't indicate anything.

agreed. I've personally looked at both and both are excellent but not sure I'd choose a 6boost over a full race manifold. also have now had the pleasure of a good look at the full race RB26 twin turbo manifolds for the EFR twins and the collectors on them are outstanding. even more so when you consider the space restraints they have to work with. Full Race have also experimented a lot with different grades and different wall thickness of steel and I think their manifolds are fairly robust now. I certainly have no problem in using or recommending them. I have also recommended 6 boost in the past too. seriously though, don't comment too much on Full race gear till you've seen it in the flesh. it's hard to capture properly in pics just how nice it is.

well anyone who reckoned the 9180 might be too big was way off. preliminary testing has been done and if anything we are thinking we might want a BIGGER one!! response is amazing for such a large turbo. thoughts are that on a track car it would be a good thing even on a 2.6L. yes ours is a 3L it's way more responsive than the -10s it replaced. getting the car set-up on the dyno at part throttle the thing is coming onto boost in the 3,000-4,000rpm range! my memory is hazy so don't quote me but off the top of my head at 4,000rpm it made 60kw more than the -10s. final results coming soon. the 6258 car is having the turbos installed as we speak but just having a few issues getting them fitted. but once done we'll have graphs to show. and yes 450kw+ is the aim. if the car needs more fuel pump i'm sure it will get it. no point leaving the car below it's potential just for the sake of a fuel system. so, guys. can you make us a bigger EFR or what????? maybe a 100/90? even a 100/80 would probably do it.

yes as chef certainly. piece of cake to import and register one. finding one that's worth buying on the other hand is a bit of a tall order. most are half fked by now and even finding those is tough. finding a good one is nigh on impossible.
