It is clearly just a normal GT3076R, which come with "GT3037" on the core - and a "Garrett cover" Ie, an HKS GT3037 without the HKS housings put on it

No that kind of thing can't work, DP said so!

Lol you KNOW that wasn't a fluke, right? :-P

You know I don't lie!

Of course. For the same old reasons! HTA GT3582R = 59mm inducer, 82mm exducer - ~74lb/min GT3582R = 61mm inducer, 82mm exducer - ~65lb/min GTX3582R = 63mm inducer, 83mm exducer,- ~76lb/min Normally you have to decide between the laggiest and the most powerful, In this case an HTA all but lets you have your cake and eat it too

^ the above, except instead of GTX3582R - HTA GT3582R

Wow, this was over a month ago!

That is just crazy, man! Nice work Was the 6766 totally maxed out?

Didn't see that in the listings, and the car it is going on already had a BOV plumbed up that works well. A billet 16G is something we were talking about that we thought would be good, didn't know they had them! Nonetheless price was a concern and it would be good to see how the billet ones perform and lasts before taking a punt at them, I am sure the 16G will be good for the time being

Hello new kid on the block - lets see if you can handle life on the track better than your Garrett and IHI buddies

That is a hell of a power delivery, very nice - should be a monster to drive! Did the other car get a go? Sent from my GT-I9505 using Tapatalk 2

What my car didn't drink in ethanol, I have made up for

I wish it were true for mine, I had Nismo 555cc and they behaved exactly like you would expect 555cc injectors to behave - as I mentioned earlier... meant I wouldn't get away with ethanol

Very cool, cheers for sharing the experiment - love that you are trying these things out! I am a bit dubious about the potential reliability issues, but I love it that someone has the nuts to put the effort it and no doubt market it if you can make it work. My hat is off to you for going even this far

Really anything you have which can shed light on what is happening would be interesting to look over for clues, if you are happy sharing

Do you have a dyno plot for this? With AFR etc?

Yeah fair enough, a GT2835 for an unopened RB25 does seem like a sensible proposition - it was a serious consideration for me when I did my extensive researching and pondering. At the time I got my GT3076R I had been concerned about response, engine stretch etc etc and it was not initially my top choice. I decided in the end that I was probably going to strengthen the internals later down the line so I don't want to have to redo the whole turbo purchase thing etc, and the lag difference between the GT2835/GT3071R (probably would have been the 3071R tbf) and the GT3076R seemed existent but negligable in the grand scheme so I went with the .63 GT3076R. When I first drove it my expectations in regards to response were exceeded quite substantially - it built boost quite effortlessly, I was well impressed. I would have been totally rapt with it, except I ended up with boost control issues and also early indications that exhaust pressure was going to start soaring as I started leaning on it. I ended up making reasonable changes and went with the .82a/r as part of it (given how much work was needed to fix boost creep) which I had previously steered clear of because I was worried it was going to be a lag monster. First time I drove it, truth be told I was a bit worried at the noticeable amount more doughiness under 3000rpm - but the way it came alive after 3000rpm started feeling much like the .63, if not identical from 3500rpm. After that point came years of happy motoring and not looking back, and strangely enough I never ended up building the motor. So yeah, it was my choice for future proofing - the GT2835 could easily have been "it" if I didn't think I might want more in future and end up building a new motor. They sound like an awesome unit, though in all fairness I don't think that'd be an option for me now - even for that application, some awesome stuff has come out. I'd probably use a GTX3067R in it's place, or really ... imagine a GTX 67mm compressor frankensteined onto your turbo? Funnily enough my motor was unopened and I had a 7200rpm re limit and never had any issues keeping it on boil - though you are right in the fact I was definitely wasting potential flow, while with the GT2835 I'd have probably fully utilized it's limits with a bit better response.... how much better I'd actually LOVE to have been able to find out. I was never left needing more, so was content with it and again I had the option of going cams, more boost etc etc and not choking it.

Absolutely, we're not expecting magic. The old PE1420 delivered all that was needed of it - so as long as the 16G at least matches it's flow (no doubt it won't match it's response) it will be considered a success. Turbo is ordered, hoping it will be here next week

Yes, be very interesting to see how the retune goes - I'm an unashamed 3076 fan and this car flies the flag very nicely Good luck, and I hope they get into it, I thought it was going to be done a couple of weeks ago!

Absolutely, there is no right or wrong. Anyone that thinks a GT3076R (let alone something that potentially spools better) is a lag monster seriously needs to harden the f**k up though R33/R34 RB25s are one of the LEAST laggy turbocharged cars ever made due to seriously undersized turbochargers, some people upgrade them to slightly less undersized turbochargers and get a very nice performance boost. There are people who have "upgraded" to HKS GT2535 turbochargers, which is a turbo which flows similar to a stock EVO turbocharger - ie, putting a turbo similar to a turbo which goes on a stock 2litre turbocharged motor build for midrange onto a 2.5litre turbocharged motor which is inclined to deliver it's best in the higher rpm. I facepalm whenever I hear about people on a mission to fit GT28 based turbos on them - the cropped GT30s like your own I definitely find much more bareable to be fair, but then still only just tolerate the idea. A full 56-trim cast GT3076R spools roughly the same as a late model twin scroll EVO TD05 does on a 2litre Mitsi. I know this, I've tested it with mates. While I can't say it's wrong to want silly response down low, I can I fart in the general direction of anyone who considers such a thing as a lag monster - sure, there IS lag... welcome to having a PROPER turbocharged performance car, not one destined for commuter peppiness and exponentially increasing intake/exhaust pressure ratios. Oh yeah, in regards to what is more or less my "ideal" RB25 turbo: http://store.forcedperformance.net/merchant2/merchant.mvc?Screen=PROD&Store_Code=FP&Product_Code=NTGT3076HTA&Category_Code=Turbo-FP From memory the price is more or less comparable to a GTX3076R when you factor in the price of the turbine housings which come included with the HTA, but frequently additional cost with the GTX.

What do you mean by that? Their performance? Where to get them? Or what they are? The short of it is the HTA GT3076R is typically a Garrett turbo which has a modified Garrett compressor housing and FP designed compressor wheel as an upgraded equivalent. In a most cases the comp wheels are smaller (or at worst, the same size) as the equivalent Garrett GT, and flow around 15% more than the previous cast Garrett wheels. They've actually been around for quite a number of years and quite well proven, in circles where they have been used and distributed they are very well regarded - and imho make the GTX wheels Garrett released a bit redundant... especially seeing as the HTAs seem to perform at least as well given they seem to make similar power but the HTAs spool better than the GTs while the GTX were if anything a backwards step in response.

You mean actual variable nozzle tech? If so, I love the innovation but there is no way I'd run or recommend one until they start showing any sign of realistic longevity - no doubt about performance gains, but even in OEM they just don't seem reliable.
