Sup guys my mate Avacardo is gosting a cruise (quite a big long one about 2hrs) for anyone interested

I'm in for it Dean if nothing crops up! How's the recovery going? Not trying to get me arrested again? [emoji23] Seen a beast exactly like your 34 parked in Bennett Springs today but a coupe. Same colour and rims. Put some pics of your car in my screen saver at work. The boys loved it! She's a tidy machiene. Hope all is well with the wife and baby!

Car stereo will never compete. 901's, gale gs401a, dual mordant short centres, 301 rears. 2x Yamaha 1x marantz and a 140wpc nad from the early 80s either watt meters.


Just a thought! Might have fitted the Nissan:-o DSC_0265.JPG.84668072bdd034387456de3d5f9f2ac4.JPGDSC_0268.JPG.6418231729271f783d2fbd5962b365e0.JPG

901's 250wpc at 8ohms, so beautifully efficient chained to the rafters. Running gale g's 401a's as subs. Audiophile at home. Got 2 Yamaha 1 marantz and a 140wpc nad with watt meters from the early 80's.
Anyone ready any of the hypergeat turbo thread? Currently up to page 539 since friday night, my head hurts


If you want the best balance, smaller highflow good for 250ish on 98 then run it on e85 for high 200s and minimal lag for everyday Street use. Enough go to get you solidly moving but without the 3500+ rpm boost threshold.

I'm not sold on the benefits of the 300kw+ ones vs off the shelf big buck engineering jobs. Surely a gtx3071/3076 will perform better for transient and response even if they make the same peak power.

Yep. I normally go to Whiteman park and Malaga every year. 3 mins from home both directions. Followed every stage a few years back.

Went to the zig zag stage ages ago. Got all set up over the 3rd hairpin. Set up my camp chair got out the esky with some beers and chicken sandwiches. Looked down after about 15 mins to see I'd disturbed some Kalamunda locals being massive bull ants. All over the chair esky shoes and sandwiches were totally null in void with ants. Had to do a massive f##k dance shake everything down and spent the rest of the day with full paranoia and little itches that might have been more ants in the pants! Leeusseer:-)

I'm laggy up to 3500 with the SS2 but it doesn't affect it too much with the 4:1.1 and 5 speed if your in the right gear at the right time. With more power I'd definitely be looking at a lower ratio. So 115-120kph isn't 3000rpm cruising. Having said that the exhaust planes out pretty quiet for a 3" straight through and now we can give it "justice." On the stereo. Even 3-4 at 18psi didn't lag at the drags and it kept pulling hard at about 6750rpm over the line at 177kmph. Have shifted 5 at about 195kmph and it is always over 3500rpm in the rev range when you pull the next gear. With a kizza motor and tuning I couldn't see it being a problem?

Yep. Agreed. How did it run after the clean?


Same same. It starts better on cool mornings but only marginally. Perhaps a touch pokier taking off but maybe just my imagination. Fuel economy appears unchanged. I'll know by Friday when I refuel

There isnt a whole lot of info on rb30dets in my desired relms of use. Most rb30dets area drag monsters...

Im thinking atr43ss4/5. Ss2 mite chocke my rb30


Right rb30.

3076/3071 minimum. Anything that uses a stock rear housing isn't going to flow enough exhaust and will choke hard up top.

Gtx3071 with a 0.82 hot side should have full mumbo at 2500 but with 300kw potential. All the meaty ass midrange without making so much power that it's unreliable and laggy, if you want power more progressively use a 1.06 hot side.

Gtx3582r with an 50mm external gate is what i was also thinking. Either way i think external gates gonna be better



Ss2 would be punchy on a 3.0l. What's your top end power goal?


High flows have been tried on an rb30 years ago. It was a cheap build basically stock Na bottom end with the 25 head and it came on like a light switch but come 5000 it hit a wall, by 5500 it had dropped about 100kw from memory.

    • Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.
    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
