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.

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,

      R33 GTR running -9 with no tune

      By Murray_Calavera · Posted

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      By GTSBoy · Posted

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
