enough talk, overlay the dyno plots.... lets see which has more under the curve...

and not using some demo car thats been tweaked to get a curve.

Problem with that is it’s not always telling the true story.

Take Garrett -9 & -5

-5 being the larger, more power… However…

Loaded in 4th, they come on almost around the same RPM, about 200-300rpm different. However on the street, on/off throttle you can clearly tell there is a massive difference between the two and it is much more than 200-300rpm.

Trent is a very experienced and reputable tuner here, he's not going to modify his dyno for me getting happy results and this is not what I'm after either. There is no tweaked demo car, what mods has been put into it is clearly listed in my thread. Have a read through it, pretty much every one's getting similar or better end results and there are also few whom are working through their builds.

The SS1PU billet comp wheel FNT layout is also in my thread, its a good idea to read.

Im not saying the dyno is being happy for you or anything like that, but your setup has obviously been gone over so many times and rejigged to get consistency its better to see results from people who have chosen a turbo, installed it and got it tuned so thats its totally not biased and a real world example, like were not grabbing results from the HKS demo car are we imagine the argument we would have if we did...

no here is saying anything bad about HG turbos themselves... just laying out the differences between the choice in turbo selection and whats involved to get the setups right.

I have never rejiged the car for better result, I always rejiged the turbo for better result.

I specifically did not build a "demo" car for showing, I'm aware no one will get that sort of result with a every day car. My car's mods are basic and clearly listed, its just a healthy motor with stock head, cams, cam gears and manifolds, typical what most people has. Just Every thing working the way they should.

How ever diagnose what causes power lose is some thing that I'm in the process of sorting out, as every one runs different parts and have a mind of their own. Pretty much all customers whom have sorted their issues or followed my modification guide do end up getting similar end results.

Im not having a go at you or your product and I didnt mean it to sound that way at all...

but I did say 'rejigged to get consistency' not better results

whether you like it or not your car that you post up results from using your turbos is your demo car...

and we've all read how you've set it up to be a normal reliable skyline that any run of the mill owner may have, and I thinks thats great.

but I still prefer the HKS turbo, no if or buts, I like what it does and I dont mind paying for what it offers, and no one can put forward and figures or controversy to say Im wrong in my opinion....

Yeh because you're not.

The HKS 2835ProS is a great turbo, no doubt about it. It's horses for courses, as much as I would love a 2835, I simply can't afford one nor can I find one. So I went with the Hypergear. Simple as that.

I almost went for a hypergear as well...

so why is it that whenever a 'what turbo should I get for my rb25' comes up all the HG fans and mr HG himself come in and diss every other suggestion..???

I think the 2835 pro s looks great,

However price and hard to find.... Also have to change exhast, not that it's a big deal.

Am I wrong in thinking the atr43ss -2 is quite similar as the hks 2835 pro s?

But at the end of the day with either turbo I'm sure it will still go fair well :)

^^^^^^^^^^ this has been my point for months 75 (post 89), glad I'm not the only one who thinks it.

I do kind of feel sorry for Stao in a way, he has in no doubt done great things for the rb25 community, and he often feels as though he needs todefend his product. There is nothing "wrong" with his turbos, I just believe In Some instances you get what you pay for.

I have admitted before that we have paid an inflated price for the hks tag but in the scheme of things it's really not tha much compared to say a Garrett equivalent when you take into account all the extra bits and peices you need to get the car running with a new turbo setup.

If I was to go back and do the whole highflow thing again (which I wouldn't) I would still by a HG, but when you get to a point of chasing bigger numbers I think the hks does come out on top, it's the HG fanboys that seem to get the sh1ts with these types of comments but as ash said above there is sooooooo much more than a dyno graph.

Those of us that are fortunate enough to have been able to get our hands on the 2835 know all too well just how good the car drive with this turbo, VERY fast but still transient and not snappy, and great off boost. IMO and it is just my opinion I believe that is what makes for the perfect turbo, not just having 300 killerwasps and getting thrown back in your seat, you still want a degree of controllability.

any turbo you choose will be better than what you have, it all depends what you want and how particular you are with your choice.

other places to find a 2835

and I actually scored a brand new 2835 ProS turbo for $1600 delivered....

I found the HKS intake pipe, for practically nothing (cant remember) and had a dump custom made for $250...

done... search, be patient and you will find...

I personally think its wrong to compare the hks and the HG turbos as they arent even remotely in the same price league!:whistling:

No doubt Mr HG offers great bang for ya buck its great to compare dynographs but is it like comparing an R35 to a Lamborgini????:blink: quote name='Irwin123' timestamp='1323337455' post='6144921']

I think the 2835 pro s looks great,

      Duncan's V37.......race car?

      By MBS206 · Posted

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
