So that was the disaster I call "talk to your tuner before buying parts". I still have not learnt my lesson.

Basically Racepace tuned the car to a nice , safe and reliable 234rwkws. After about a year I wanted more grunt and everybody says cams do that for you on an RB. So i grabbed some Apexi, 260/9.00mm cams, threw them in with a new timing belt, idler bearings and water pump and tuned away. Hours of dyno time later, the thing was las laggy and didnt respond to fuel and ignition whislt tuning as well as it did with std cams, suggesting the engine was now over cam'd. So back went the std cams and voila....engine was a lot more responsive and because I had an appetite for more power Racepace just leaned on the tune a little to give it another 30rwkws odd at the same boost, just with ignition and fuel changes, perhaps a further tweak of the cam gears.

Tune is still rock solid with no issues, having run as high as 22psi boost with no issue and engine still has no blow by. Std cams seem to be the way to go when you have a small little 8cm exhaust housing...even with the cams the engine seems to just choke on its exhaust gases. I will try soem 256/8.5 or 26/10.25cams if the Plazmaman plenum gives a performance increase sufficient enough for me to go to a 10cm exhaust housing.

i am ssuming you are running the td06 20g l2

no more grunt cause the f**ker will not make more that 260-80rwkw

you need larger

the 25g should open it up for ya fag!

Ok, so with he body work requiring attention, she sat around at a workshop for a while waiting for time, parts and the biggest factor me coming back to Australia and actually needing it back on the road.

So with some to and fro over how much to pump guards, how to mod the R34 spoiler for the right rake...and all the other usual stuff that goes with re-spraying a car...

So , after plenty of patience and hard work from the panel beater...

So at the moment car has almost got its new 6boost manifold installed, meaning its time to tinker with some more of the bolt ons I have sitting around.

The Trust Ti exhaust I want to run may not get the nod. It seems my HKS Hyper exhaust is quieter and with the gate being plumbed back with the new setup I need the thing to be as quiet as possible so that I actually get some running on the track….AND NOT black flagged after only a handful of laps

Having thrown a few brake setups at the old girl, I am hoping this will be my last brake setup that I run for a while

med_gallery_462_50_294104.jpg

Just need to machine up the mounts so that I can use the callipers with the new 343 x 32mm 32 vane rotors I have on order. Also waiting for Performance Friction to release the new compound of pad I am waiting to run.

Also waiting in the wings is a set of 256/8.5mm Poncams. It’s a huge waste of money because the engine-turbo setup is already a pretty good setup. But I am hoping that the new 6boost manifold, E85 fuel, will give me a bump in response and allow me to trial the TD06-25G 8cm and TD06-20G 10cm and see which setup works best, and whether with the bigger hotsides I can get more benefit from some baby cams

Yes it would be easier to throw a bigger RB in there….but still keen to see how much you can get out an RB20 setup. But with new Plazmaman plenum and new rockers covers, fuel rail etc, may as well trial the cams and see if we can stumble onto a 280-310rwkws RB20 setup ;)

Just stumbled across this Roy.... I feel unloved!

Great thread mate, I have so much love for the 20's, without a doubt, the most reliable and fun car I've ever owned!

Your old white Weds wheels could tell some stories, amongst many other things, they've been on fire with you, and through fences in Tassie with me ;)

And your new 'ARC cooler looks very familiar, I remember tracing and cutting the stencils to spray on the ARC logo back in 2000. That 'cooler cost me $2800 landed back then, and it was 2nd hand! lol

Here it is on my gtr that I built from nothin;

GTR.jpg

Grabbed them locally, was tempted to grab a set of the 332 setups a few weeks back but knowing how good the F40s are on my car I am concerned that Stoptech only use a 38 and 34mm piston in their R32 GTSt kit. Plus I went to all that trouble with wheels to make sure I can clear a 343mm rotor, it would be a crime to go back to a 332mm rotor. With my upgraded rears I would prefer a little more front bias in my kit. So the ST40s i grabbed have the same piston size as the R33 GTR Brembo / F40

The Stoptechs have a bolted bridge that you remove, then they are basically a cross between Brembo F40/50s and Porsche 4 pots. The Stoptech calipers have a large and confusing number of piston combinations where they use the bigger rotor to give you more front braking torque and thermal capacity, but use smaller pistons so that they work with the std rear brakes, master cylinder and dont make the car much more front biased.

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
