Umm.. sorry, something happened, I recall just klicking "submit thread" just once.

Hi! I´ve searched through all Euro-shops I´ve been able to find after some exhaust valves for my R34 GTT, but no one seems to have them in stock, not even the aftermarket Ferrea and Supertech-valves, and they all have estimated delivery by at least three weeks. So, is there any Australian shop/store where I can ask for valves? I need two exhaust valves for my RB25DET Neo, doesn´t matter if they are stock, or aftermarket, I just need them quick. Thanks in advance/ Mattias@Sweden

Hi there. I'm finished with my new bottom end on my car, next week it's mapping time. Last year I got 474rwhp (353rwkw) on 1.5 bars of boost from my GTX3076R with a .82 exhaust housing, I don't want to swap for another intake as it gets a lot harder to get the car through the yearly inspection. Has someone tried to take the stock manifold to the limits? where will it stop giving more horses? HP-limits and, or boost-limits? I would be happy to push at least 530rwhp with the stock manifold now when I got a fully built bottom. Most important specs: Poncams 260/9.15 in/ex. GTX3076R .82 exhaust housing. Link G4 ECU. Ron 98. Thanks/ Mattias@Sweden

Hi! I'm building a new engine for my R34 GTT. When I started assembling it, I noticed that my current engine block (which is from an old RB25 with hydraulic valve lifters) has a oil restrictor to the VCT, while my old Neo engine block does not have one. My theory is, that maybe the Neo head has a built in restrictor, therefore not needing one in the block? So: My old shitty Neo-block does not have a restrictor for the VCT. My renovated nonNeo-block (RB25 with hydraulic valve lifters) has one (photo below). Do I need to remove the restrictor, or can I just leave it there? Help is much appriciated as my build is currently on hold because of this.

Hello! I've searched the web without some good answers. My R34 GTT is currently mapped to 474whp/560wnm at 1.5 bars, the head is ported, with Tomei 260/9.15 cams, turbo is GTX3076R with a .82 exhaust housing, + supporting mods I'm building a block with CP pistons, Eagle conrods, Reimax pump gears and Tomei oil trap (with an external oil drain from the head). I would like to make at least 550whp, but I'm not sure if the stock intake is up for the job. Most people in Sweden buy another (Greddy or Jun style) intake as fast as they hit 350whp. So, how far can I go with the stock intake manifold? Thanks/ Mattias@Sweden

Hi! My Stagea 260RS is currently mapped to 575hp (497awhp), the guy who tunes my car told me to not go higher than 1.4 bars of pressure with my GT2530 turbos when running a stock bottom. If I don't recall wrong, I've seen people here with ~600hp on stock bottoms. A friend drove his R32 GTR for 80 000 kilometers with 560hp and a rev limit set to 8500 on a stock bottom RB26 over a 5 year period, the oil pump gears finally broke due to usage of launch for 2 summers. How much boost/hp is safe? Thanks Mattias@Sweden

Hi. If I want another differential for my RS4S, what should I be looking for? I want a 1.5 or 2-way differential. Is there any Skyline differentials that fit the RS4S S2? Thanks

In Sweden, 99% of all RB26's running more than 650bhp uses E85 (and that is a few dozen). Good. It keeps the engine cooler. It keeps knock levels lower. More power and faster spool up at the same boost due to possibility of running more aggresive ignition. It's enviromentaly good. Bad. You need to change your engine oil more often, the alcohol thins out your engine oil faster than normal gas. It requires roughly 1/3 more fuel compared to normal gas. It requires more power from your coils/spark plugs. Old fuel lines might start leaking because alcohol dries gum. The standard fuel pump will break pretty fast.

Yo! Here's a few new pics now when the summer came to Sweden. I also mapped the car with the new GT2530-turbos and the HKS 264/9.1 cams. 497whp at 1.4 bar, that's really impressing power at such a low pressure (still stock bottom). Here's a movie, 50km/h to 220km/h: http://www.youtube.com/watch?v=OEAbxzyr8LQ And here's a movie from the mapping (making ~400whp at 1.1 bar): http://www.youtube.com/watch?v=lVp8rNBlRgo And here's the photos!

A few new of mine.

Commsman; 3-4 months a year we have snow, the temperature is usually around minus 15-25 celsius, our summer cars usually wait in warm storages the whole winter. Spring-time starts in a few weeks, I'm longing for it. The video in my signature is my old r33 GTR, built it from scratch. Autronic SM4, GT35R, forged bottom etc. It made 470whp/540wnm at 1.5 bars with a 0.63 turbine house, i traded it against the Stagea. Shane: That's what I'm talking about!

Commsman: I think there's ~25 or 26 Stageas in Sweden right now, 4 of them are 260RS. Actually mine is'nt a real 260RS, it's a RS4S with a Autech Swap kit, here's my car: http://www.garaget.org/?car=277039 Iamhe: I'd rather go for more power . KiwiRS4T and Dan, i will try it once the snow melts here-arounds.

Ok, thank you Dan. I'll just keep it as it is then. Sorry for me being so "bitter" earlier, had à bad morning at work .

Why is it a stupid question? why would I buy an S13? I appreciate the car and intend keeping it. What is your problem? KiwiRS4T: Thanks, that's one answer I've waited for! My car has N1 BB turbos, HKS Hardpipe kit, Mine's front pipe, Apexi PFC, larger intercooler/injectirs etcetc. It makes 420whp/492wnm at 1.4 bars, so it's far from stock. Next upgrades would be 2530 or 2860-7 turbos and Poncams, the rest supports at least 600 engine horsepowers.

Josh; they probably stretch further than yours. If you can find something that answers my question, i'm thankfull, I think I'm the first to ask this. 045HOW; Seriously, did you even read my post?

Why do people like you exist on forums? is it so damn hard to stay on the topic? I had thoughts of writing something like this but thought that wasn't neccesary on SAU..: It's my f*cking vehicle, i do whatever the f*ck i want with it so please, dont tell me why I am an idiot for wanting a 260RS, but RWD. Joking or not, it's irritating. JoshM35; 100hp? you think I am one of those stupid persons who thinks that airfilters give's 5% more power? like "aah yeah i have this BMW M5 with 510HP, I added a sports air filter, it says it gives 10% power so now i have 561HP!!!!!! then i bought iridium spark plugs and they add another 5% overall power, so now it has 588HP. I also ordered a Supersprint exhaust-system, it adds 10% power to, so it will be doing 646HP! YEAH! not to mention Shell V-power which will add 5-10%! omfg! that's easily 700HP+++!!!!!!!???!! Sigh..

Hello! I dad a discussion with a few friends about turning my Stagea 260RS into RWD, and if there's any gains in doing so. The idea was to remove the forward drive shaft and the fuse, there would be no harm to the central locking clutch, so I don't want a debate whether it will damage anything or not. Performance wise, it wouldn't become a clean RWD because of the front differential etc. But still, do I gain any performance just running it RWD? it only needs to run 2 wheels, so in my world it definately makes more power to the ground, power that the fwd normally consumes? Let say a 100-200km/h (60-120mp/h) where the 4WD start don't matter, would I see a difference in performance here? Please, enlighten and discuss!

Ok, so i won't have any fitment problems with it? seems a bit strange if the front pipes are equally long to the Skyline front pipes due to the Stagea cat-back system being longer than a Skyline cat-back. It fits R32/33/34 GT-R:s. http://www.rhdjapan....line-gt-r-11747

Here's mine. Autech Stagea 260RS, Apexi PFC, 650cc injectors, Apexi intercoller, HKS hard pipe kit, Tomei fuel pump, there's more... , unknown ball bearing turbos pushing 418hp and 492nm at 4 wheels, 1.4 bars. HKS coilovers, Works 18x9.5" wheels with 245/40-18" Dunlop.

Hello! I'm looking to buy a Mine's front pipe pro, Nengun has them for all Skylines and also the Autech Stagea. When i asked RHDJapan for it, they said that it's the same front pipes for the Skylines. Is that so? Thanks Mattias

Hello! According to the sheet i link to here: http://www.gtr.co.uk/forum/159766-what-turbos-260rs.html There's turbos called Nismo 260RS, could those turbos be the one's in an Autech 260RS? If not, what turbos with what capacities does an RS260 have? Thanks/ Mattias@Sweden

Hi there! I saw this old video today, then a friend told me that it could be an Australian Skyline, so i'm linking to the vid here: Is there more pictures of this Skyline or similar Skyline's with low wings? i think it looks astonishing, there's really no "low wing"-Skyline's in Sweden. Also, what brand or make is that wing? Regards Mattias@Sweden

Here a few of mine, the GT3582R is nowadays a large Borg Warner.

I have decided to go for poncams again, but i´ll buy both inlet and exhaust new. This time with the 260 degree exhaust cam, instead of the 252 which i have now to have some more high end power. Thanks for the answers!
