There is only one GT3040R in that thread which I have seen, and it was making ~300kw @ wheels with stock fuel system - the guy never came back (that I am aware of) with a result using the 555cc injectors he promised. Do you know of any others? I know people making well over 300rwkw with GT3076Rs on RB25s, so presumably people would make even more on GT3082Rs.

I think that'd probably be the way I'd go, especially if you have it in a RWD - I think lack of power isn't going to be your biggest problem For interests sake, if I read it correctly the 1.06a/r GT30 turbine actually flows better than a .82a/r GT35 turbine, and if that is correct and I am not missing something else (which is entirely possible) then using the 1.06a/r you will actually be able to make more power at higher boost than the typical .82a/r GT3582R. Given that the GT design is fairly well suited to bigger a/r housings, and that there is less rotating mass, it makes me wonder if you could end up with a combination almost capable of making similar power AND better response to with a GT35R. I hope Discopotato03 finds this, and enlightens... or shares an opinion

Well my personal opinion/what I would do in your position would be run with the .82a/r with the stock cams and pour a bunch of boost into it make the most of it being a punchy set up. Regardless of how much power it makes, it will be quite punchy though you probably won't have the full top end monster you could have. I reckon it could be quite a fun car though If I remember rightly the .82a/r GT30 turbine side has very similar exhaust flow to a .63 GT35R, and runs exactly the same compressor housing and wheel - so I can't see why it'd not do anything a .63a/r GT3582R would do, maybe SLIGHTLY less flow and better response. Its when you start getting into .82a/r and 1.06a/r GT3582Rs where you will start losing out in my opinion, I'm no expert though haha. If you intend on later on down the track upgrading cams etc, then you'll have a good idea of if the GT30 turbo is going to be sufficient - going GT2860s or GT2530s would probably be a waste when you already have the turbo and don't have the cams to really justify the extra flow up top. Again, only my opinion.

Hiya, sounds like quite a neat build - though I'm not sure why you'd go to so much effort and stick with the stock cams, I'm not entirely sure if or how much that may conspire against you in going for your power goal. Which turbine housing are you running on it, the .82 or the 1.06?? Also I'm not sure what dyno you will be running on, some of the aggressively low reading dynos over there you may struggle to get that out of a GT3082R though 340kw SHOULD be achieveable on most I'd imagine though no matter what you will be pushing the higher end of what a GT3082R can do. I know someone over here (NZ) running one on his RB25DET R32 GTSt and on slicks he has run 10.1 with a small shot of NOS.

Precision SC61 or Garrett GT3582R is fine for mid tens - they are much of a muchness power wise but the Garrett spools better. One of my mates did 10.6 on MickyT drag radials with a full weight R33 GTS25t using Jun ~260deg cams on an RB25, 272deg are pretty overkill in my opinion. You should be able to make do with 260deg Tomei Cams, and not revving over 8000rpm - another mate of mine was running 500whp with a .82a/r GT3582R on 1.4bar with those cams on an RB26, trapped over 120mph with a full weight R32 GTR on his first outing. With a S13, pure rwd, much less weight and exactly the same setup with decent suspension and tires you should be well into the tens and >130mph.

Have a look at their website www.htlracing.co.nz and get in touch with them there, or at least have a look there. The car will be racing again at Jamboree in Oz this year.

Looks laggier than mine :|

I thought dredging up this old thread would be the best way out pointing this "new" turbo out to see if the masses (ie, DiscoPotato...) have any say on this new thing ForcedPerformance have started playing with - their new "HTA" design turbos. Of most relevance to this thread, the GT3076HTA which claims to both spool better and pump more air than the old 56Trim GT3076R - it seems to use a 7blade 52trim 76mm wheel of some sort, which I thought is the bad juju? Its an interesting looking inducer though. Thoughts? http://store.forcedperformance.net/merchan...y_Code=Turbo-FP

Very nice pics, and bummer to see it went wrong first time - gotta gut you. I was sure I've heard that unless you're going mental with it, theres no point doing any more than maybe a basic tidy up of the ports - no reprofiling or anything as they're so good stock. I know not everything you hear is true, but sure that I've heard that its not uncommon for RH9 cars to not have had any work done to the ports on the cars - just big cams and whatever is needed to fit them and actuate the valves correctly.

Gah wtf I'm sure I wrote more in that post. What I must have deleted was that while its a good idea, and many forums have done so - I suspect if someone isn't going to search the forum or use Google to find the information, how much of a pain in the arse would it be if people (I'd be willing to help if a team effort was going to be put together to write stuff up) never actually used the data compiled?

I suspect I'm still under that post count I got this for $350 - does anyone know if this turbo will make a decent upgrade to my old VG30 turbo (housing pictured on the left)? Will I get full boost by 3000rpm? Chur: (j/k)

Goddamn - congratulations!!! Awesome to hear someone getting really close to the 7s. Be neat if it gets there soon, when Heat Treatments get over there it could be a particularly epic show - may be the first time the world has seen side by side 7s from GTRs

Nevermind, I just discovered this deserved two threads.

Nice numbers! What is the car/engine?

Looks like the next time this car runs down the 1/4 will be on Australian soil Fingers crossed you get to see some silly fast passes.

Not sure what their target is - I think they just reckon they can go quicker than they did and would like a mid/low 7. I guess there is the hint that people might be intending on giving them some competition so good to keep it on form haha. Lots of fun seeing it get quicker, nonetheless. Seeing a R32 GTR charge down the track in sub 8s really is a sight to behold, a lot more exciting than your typical tube RWD etc - looks a lot angrier.

Last weekend HT finally got the thing out for a meet without any niggles, and managed a 7.80 @ 182mph on its now getting old slicks. Looks like they are quickly coming to grips with the new setup, should be very interesting when they decide to start winding the power up!!

Awesome! Congrats The crystal ball has at least one new GTR (in the world) doing 7s in the next 6 months to a year...

Thats a very nice setup man, I look forward to seeing how it comes out. Its basically what I'd like mine to end up being like - capable of a LOT of very useable power.

I put a video response on that youtube vid of my Skyline (and a mates Supra - unfortunately I don't have video editing software to remove that bit ) blatting up the road in a similar kind of way, you can hear my Garrett 56T GT3076R with .82a/r rear housing doing the same thing. Definitely has a noticeable difference in spool sound etc. Exhaust note sounds a bit different though there are a few differences in setup between mine and Jasons - one of the majors being his being tuned on 17psi with 95 octane and mine being on ~1bar on 98 octane.

Given its essentially a TD08 which is an old Mitsubishi truck turbo, it fits into the same umbrella in my opinion. Even a modern Borg Warner S372 (rough equivalent to T88-34D) will be laggier than a T04Z though. Its still plain bearing, and its still bigger.

They're both rather laggy, but the T88 is VERY laggy. You get that with a bigger turbo which is only plain bearing, and its also overkill for 440kw @ wheels.

Good luck with that Granthem Cheers, I'd really like to think it could be done though I have never seen anyone get anywhere near that quick on street tires. I've not let anyone else drive my car, I actually done fairly well in other peoples cars though. Other people have driven my car (not experienced drag cars) and succeeded in doing impressive burnouts hahaha. Runs are that few and far between that its hard to convince yourself to give the car to someone else to have a go, especially when most of the experienced/fast guys here are running AWDs or drag radials so the launch etc isn't really comparative. Again, I know of hardly any Skylines here which have gone faster than I have on full street tires - even with more power than me. The only ones that have are trapping >115mph. If you're ever in NZ, you're most welcome to give it a shot - I'm always keen to learn haha. Otherwise, any tips on launching an R33 with a solid single plate clutch and a .82a/r GT3076R on street tires and/or drag radials please let me know The car was piece of piss to launch with the stock turbo, I just never actually managed to get to a drag meet where the track was actually dry. I got the thing down the strip with catback exhaust and pod filter (stock intercooler and boost) in 14.1 on a greasy damp track.

Looks like a boost leak to me. Turbo is drawing air in through the AFM but the air isn't making it to the engine as it is escaping somewhere - so the ECU is pouring fuel in to suit the amount of power you SHOULD be making/the amount of air that should be making it to the motor but since the airs not there you are just running really rich. Times like this I wish I had an AFM, as I think I *might* have a boost leak though not too sure.

Maybe T517Zs or something of that sort.
