Gets tricky, depends on weight of cars and how hard they are being pushed etc. There are R33s and Soarers running mid 11s with GT3076Rs, SimonR32 here has run a very low 11 with his lighter R32, and

as for something with more potential I agree, get a good clutch and big injectors, good manifold etc... get good supporting mods.... and spend time on setup your rear end to handle it all etc... as

I dont know... with the .82 rear and larger front the power delivery is still not going to be as brutal as the 2835...

however in saying this I have not driven a 3076 .82 with external gate on an RB25... but i still cant see it having the agression of the HKS unit, which for me is where the fun is at.

(i have driven an ex gate 3076 .82 on an RB25/30 however... shit was like driving on ice)

you would like mine...I dunno if you been in BIrds car, its pretty quick and very smooth, but mines alot more aggresive :devil:

its a bit more nice without the screamer now..

definately more fun if you ask me though it is hard to tell which will be faster without racing em though

Like for like the cast GT compressor wheels are typically apparently nearly 30% heavier than the HTA ones - I'd go out on a limb and say that the GT3076R-HTA wheel is probably lighter than the GT3071R (and GT2835) wheel. Obviously you then have the .82 (as you mentioned) to factor in, but then you also have the greater wheel efficiency of the more modern design... quite a few swings and roundabouts there - but I am more thinking about the net result of the conversion than the initial spool. I personally loved the .82a/r GT3076R, and the HTA is only likely to be an improvement :)

Dyno shows 4000ish on high boost runs..... Feels more lively on the street that what the graph shows though :)

that's what I meant... 2835 was up and running by about 3250...

I dont doubt the 3076 makes the power... but i reckon it's never going to be as responsive as the smaller 2835 no matter what the configuration

No argument there... :)

Some info on the one result Lithium mentioned was in here -

And there was another thread too "370kw" in the title i think it was! Interesting!

I also noticed there was a VQ result to be expected but i never saw anything posted about it since...

Do you have a dyno plot of full boost by 3250? How much boost was that?

not on me... I can show you one of my old engine with 98 and e85 that is pretty close, but that was a 200,000+ motor and eventually spun a biggie.

lol thanks! ill look it up!

Looking at the plazmaman plenum, the different size throttle bodies. How big is to big? or is needed etc?

I run the smallest one they have! I think 66mm or something from memory!

That is not a bad innings! Mine is making the power on a 150k unopened motor :ph34r:

VQ is still sitting on workshop floor, but we have since turned back to utilising the existing SR instead :) Wanting something more brutal than linear.

      The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.

      R33 GTR running -9 with no tune

      By joshuaho96 · Posted

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.

      I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋

      Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
