Who told you that you need to change the blow off valve ? Stock ones are pretty good... There's a GTR on here making over 600rwkw on stock GTR BOVs... the GTSt ones are pretty good as well...

300rwkw+ is possible on stock internals, but it won't last long.. either your mates are lying about having 300rwkw, or thier dyno is reading high, or thier engine is about to go bang very soon ...

As i just mentioned, one dyno may say you have 300rwkw, another may say 250rwkw....

300rwkw will run 10s in Commodores, a well setup Skyline will do better than that I would think. 250rwkw in a well setup Skyline would probably run an 11 or go close.

If you want 300rwkw, just get the dyno operator to put the temp probe next to the exhaust...

yeah you could manage mid 11's on drag radials i would expect

depends, is stripping weight an option? is it a dedicated drag car only?

will it be street registered?

Its street registered i guess i could pull out the rear seat.

No one told me I know the stock bov is good for that. I said A BOV IS A MUST ON A TURBO CAR....

Mates are not lying was their when the cars were dynoed, dyno is calibrated regulary. Their engine could be ready to go bang true i hope not though. So would it be fair to say that a constant 250rwkw is alot alot alot alot more safer than 300. The answer is obviously yes but is their that much of a stress on the engine putting that extra 50 kw into it

Apart from asking a commonly asked question...why give the guy a hard time.

And 300rwks car will spank a 250rwkw car at the drags...thats like sayign a 200rwkws RB20 will be quicker then my laggy 235rwkws...who give a damn about mid range when you have top end and lookimg to run a good qtr mile time. You leave the lien at 4,500rpm and the engine never drops below 5,000rpm

Throw the 30R on it, get a very good clutch, some good drag radials and with plenty of practice you will end up running in the 11s...

Finally someone on these forums that knows what they are talking about, Cheers.

I don't know of any .63AR ratio housing for the GT30R but it would be a bit small (as in lacking gas flow capacity) for the compressors performance potential . Realistically you should be thinking of the .82 AR ratio Garrett housing or HKS's .87AR ratio GT30 housing as minimums for that compressor and power output .

Cheers A .

LOL, wake up. I read the posts you linked up and the information was vague to say the least. What is the point of having these forums if you cant even ask a question. Dissapointed to say the least.

uh oh! youve back chatted to mussolini!

seriously nismoid, do you have to answer EVERY post with a "STFU and use the search button" post?

lighten up dude. is this a forum or a dictatorship?

:D

that should fire him up.

:D

:D Maybe.

But no point asking what others have done IMO

Cant say none of those dont contain the info.

I've read them all, they all do.

3" is not enough in reality.

Anyway, 3037 with .63 will not get you to 300rwkw

Why do you want 300rwkw? Any reason or does it sound cool in the pub?

But my search found a just a couple of results.

I mean this took around 3 mins.

I highly doubt the search button is broken again :D

If you take the time, there is loads more info which will tell you

Yes Ive noticed this "advice" in a few threads.

Now you posted 15 URLs which require 20 seconds between each search (as flood control is enabled) which equates to something more like 5 minutes + client server lag time + typing search criteria time + scanning results time == a lot more than 3 minutes...

Maybe you should post your search criteria in plain english instead of the URL as it may actually teach people to use the search button.

Also, shen I read this thread I cant believe how many of you did not read the question, rather jumped down this guys throat for stating a clear goal = 300 rwkws.

300rwkw and minimal lag are not possible

cheers

Now my suggestion is a HKS 2835 ProS - while not rated at 300rwkws there are a few people that have done it. Im getting around 270rwkw on an average tune and it has hardly any lag whatsoever and good mid range too and is perfect for street.

Anyway, thats my 2 cents worths ;-)

I used 3037* as one search option

3540* as one search option

The first two, took me about 2 mins. As the same bunch of links was posted last week when this very similar question arose

Then *300rwkw* as the 3rd in my more recent post

Thats all, no bullshit, no tricky options.

One must remember to change the default search days from 30-day to "any date", thats really the only trick to it.

Hope that helps you use the button to its ability

cheers

I would decompress the engine if I were you... 300rwkw is fine on a stock healthy RB25, HEAPS of japanese guys have done it. JMS R33 did it for years, my 33 did it no probs BUT the big thing (and this is according to japanese experts) decompress the engine first - HKS 1.6mm headgasket gives an 8.6:1 CR - which is safe accoding to the experts :D

The 3037S would go close I recon, I ended up getting 290rwkw at 1.2 bar, at 1.4 it made 321. That was with the 0.87 turbine housing, had around 1.2 bar at 4000rpm. When I initially put the turbo on, it had the 0.61 housing, and boost hit so hard at 3000rpm, I never even bothered trying to see what it would do, anything above 1 bar was unstreetable, but with a basic (15 minute) matrin donnon tune it turned out 256 at 1 bar.

3" exhaust will be fine, as long as there are minimal bends and not much else :D

good luck.

Decompressing the engine is a cheap and good idea, i hadnt thought of that, thx. Is there any difference in the HKS 3037 compared to the GT3037? I thought they were the same its just that HKS are more expensive. Appreciate all the positive comments and the people that actually read my 1st post and didnt try to cut my)throat. To the people that did you made an arse of yourselves :cheers:

the compressor wheel is different, as is the compressor cover and the inducer - which you can only buy from HKS. The HKS turbo has a split type inducer to prevent surge, and a 0.6 AR compressor Vs the garret 0.7 on the gt30

I have seen a few people try and get the same results from garret gt30 turbos, but none have I seen that can compare, both in how early they come on boost, overall power top end, midrange, infact everywhere - chalk and cheese.

My HKS 3037 was coming on boost with a 0.87 turbine housing earlier than guys I know who were using the gt30 with the 0.63 - with the 0.61 housing on the HKS turbo, boost was hitting very, very hard at 3000rpm - anything over 1 bar and I just couldnt keep traction - in any gear at any speed - it just ramped up so qiuickly. With the 0.87 it was a little laggier, but you could control boost with the throttle. At WOT in 4th gear, made 1.2 bar under 4000rpm all the same.

bottom line, IMO, spend a bit extra

Im starting to like the sounds of this hks3037 with .87 rear. Steve have you had the chance to run your car down the 1/4. I d be happy with 290rwkw on stock internals.

    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
