i found some results with that turbo and they werent to flash..

As i said ultimate power would be nice but for the price and extra stuffing around im happy to trade power for response if I can..I am not looking at the td06 JUST because it is smaller but because it is more suitable for the application all round...

Trying not to rush into turbo choice this time Scott, did that last time and look where it got me...I though I was getting a 3071 didnt I :/

Thats a completely different can of worms.

Im going to go there again and say, maybe you should send your turbo to Hypergear. You already have the right bearing cartridge, turbine and shaft. He can redo the cold side for you to a proper 3071 spec and make you a skyline specific rear housing that will actually work.

Hey I bet you can do it cheaper than buying a kando! And you wont need to consider changing anything that isnt already there. Ask him to make the new front cover the same dimensions as your current one! Just send PM dude.

yeah i have spoken to him, in person he has seen my turbo and he told me to sell it and buy another one :laugh:

by the time I sell this it will almost cover the costs so it will be cheaper to go Kando ;)

f*k it its all going on ebay when i get home...lol

doesnt work that way that turbo has proven to not so successful. As i said its too much power on a stock mani..

Of course i would like t67 power but itstoo many extra coat and i would like my engine to last so 260ish would be fine..now seeing as im going smaller may as well trade some power for response. So while it may not have the ultimate top end of the t67 it should be better everywhere else..

So they are no good with a 3inch housing versus 4 inch?

cheers

lol ..i'm actually trying to find them but no luck :(

I did find this though :)

but anyway Im not saying the 3 inch cover is no good It may be fine my main point as stated by Trent was the manifold being too restrictive for the turbo so I dont see the point in putting a turbo on that the manifold cant flow, may as well go a size down if wishing to retain standard manifold..

Do you think its a better choice than the sl2-20g?

Are you gonna run E85? if not then going off my bp98 results you should be right on the manifold limits...

I dont need over 300kw ;)

thats what I thought until I got there!

Naa i think the SL2 will be great on the street!

The only time i'd like more response from my setup is at really really low speed corners in 2nd gear IE Intersections or roundabouts, with the stock setup you can get the thing sideways with a flick and some power the T67 is still spooling so you can either clutch or wait till your through the corner for the boost to build, then you just fry the tires in a straight line haha

Its perfectly matched everywhere else though eats the twistiest hills for breakfast!!! Can't wait to get it to the track!

Arthur T3..damn you and your external gate video's..lol, i keep going back and forward between the T67 25G and the hypergear ATR43 SS2.

I already have a few turbosmart gates laying around. i want 290-320rwkw thorugh a auto,(probally lose 20rwkw with standard torque converter over manual) so the kando is probally a better choice for peak power,

but the hypergear can be fitted up in a day easily, and its going in the wifes stagea so i am not sure how much downtime i will have..lol

But its tempting to jam a 3 inch cover T67 on a standard mani with a gate hanging of the exhuast housing

I also want to be able to tow my R31 with it..lol

cheers

A T67 is another name for a TD06SL2 (they both refer to the same rear end), just to confuse you some more...

Think of a TD06SL2-20G as similar to a GT3071R and a T67-25G as a GT3076R!!!

Unless you are desperate for every tiny rpm of response I would suggest a T67-25G

We are yet to test the SL2 but it definitely looks promising. It wont be no 10 second turbo, like the T67, but it will make for a formidable street car.

The Idea behind the SL2 is to have a SUB 300kw car with AS MUCH midrange power with the widest band as possible.

First decide what you want, then pick the parts to do it.

cheers guys , i know what i want to do with the car :ph34r: (r34) , i'm looking for the best street track setup for the least $$ :whistling: , i'm not looking for peak power , more good/strong midrange , watching simonR32's vids though it looks like the t67 is pretty good for the size, the next killer is i'm going to be running it on 98ron fuel (daily driver) so it will be sub 300rwk either way . i do have another project i was planning on putting a t67 on , so i could just try it on the 25 first (yes i'm talking myself into it lol)

Wow, 27 pages and 6 days later, I finally finished reading this entire thread. A lot of information to take in, and the different wheel sizes, etc, and different turbo names just add to the confusion! But, I think I've made a relatively informed decision as to my plan of attack, basing a few things off other members rides.

Looking at the T67, I cant really fail it at all on any large notes. Reliability and response are my only two ..... drawbacks. However, putting these into account in a Cost vs. Outcome ratio, its hard to fault the turbo. The response side of things I think can be overcome, or atleast assisted greatly with the smart use of certain parts. Herein lies my next question :)

Firstly, let me state that I'm 110% buying the T67 (I was actually looking at going a GT3582R, or a GT3788R, but the cost has held me back) . Now, I've read a little on Twin Scroll manifolds, and am seriously contemplating including one in my setup. Should the [claimed] increase in spool time (Between 300 - 500rpm) from the Twin Scroll manifold, not bring the T67 on par with me more expensive (and, presumably, 'better' turbos) ?

I currently have a GTRS, and the response is fantastic! However, the little fella's power output is somewhat.. 'old' now :) I'm looking for upwards of 300rwkw (340 - 360 would be nice ;) ..) . So, the T67 looks an awesome choice. If boost can be achieved by 3500rpm - 4000rpm, I'll be over the moon for the power it can push. At the moment, I'm seeing 20psi through the GTRS at around 2800 - 3000rpm, which is pretty amazing. So I'm willing to lose a few hundred rpm response for another [almost] 100rwkw.

2 more weeks and its shopping spree time! Lol :)

Only issue with twin scroll is the manifold needs two gates, or clever plumbing. I would certainly do it though.

Thanks for that tid-bit of info! It never occured to me.. Im guessing the twin gate option would be easier, even if more expensive.

battery, the car is currently used for street driving, however my thirst for more power is getting a little too much ;) After which time, it will slowly turn into a weekend warrior/occasional strip, track car . I would love to have the E85 advantage, but as far as my knowledge goes, it is not readily available here in Sydney. As for cams, after speaking with some very respected tuners and builders, they said it wouldnt really make that much of a difference considering the current output of the motor, and the fact that the little GTRS doesnt really flow enough to make it worthwhile.

However, a little of my own 'reading-up' has led me to believe that a set of Exhaust Cam Gears would be the better option..

Thought you were in melb from the "tuned by racepace" in your sig...

Sounds like you have done your research but i think the biggest result i have seen on 98 was 320-330kw.

    • Yuck. But it's kinda the same principle, moving timing around to make car run bad but sound good.... I went for a more spirited tuning drive to iron out a few things. Car no longer stalls, and it loved to dip RPM low when you clutch in. After tuning this (and the 4-5 tables that HPTuners/LS1 OEM ECU wants for idle air correction) it's now behaving somewhat normal. All expected because there's a new TB, new Intake manifold and that new TB which is 102mm vs 78... has an entirely different IAC passage which is smaller because ????? Unfortunately at this point I went to make further fine tuning changes to avoid it flaring up, you know... _tuning_ the HPTuners dongle died. Well to be more accurate - The USB cable died in a fashion that anyone who has ever charged a phone will recognize. After the app demanding I resync it 50 or so times (which all 'succeeded' but all failed) the device does not want to sync and I've logged a ticket with support to see if it's fixable. US Support said it was a 'storage issue' but after removing the SD card inside it and formatting it/fixing it the issue does persist. Unfortunately usually the fix is "Turn in your old dongle and pay $700 for the upgraded one" it's cheaper because I get some free licence credits I unfortunately don't need. However I'm 10 minutes down the road from HP Tuners AUS/VCM so at least I won't need to post it, and logged a new ticket for support over here. Definitely drives different. My SOTP dyno believes it's probably making 310-320kw instead of the 280 before.  It scrambles for traction a little now whereas it previously different. It drives like a bigger cam car up top even though the cam is smaller, likely due to the cam not being advanced 6 degrees. The timing is deliberately low and the fuel is very rich so who knows if this will improve on the dyno. It may, imperceptably. Also funny is removing the pineapples definitely makes the car squat more and axle tramp less. So this behavior of having more top end, squatting more, and scrabbling for traction more makes me think = more power. But I could have just been sitting on the threshold of that kind of behavior before. Time will tell if my butt dyno is calibrated right. I need the exhaust leaks fixed before dyno tune for obvious AFR related reasons - I repositioned the pipes but I'm not confident it's fully sealed even if it is better. At least the car does drive around while I cannot tweak/tune it for now. And I have aircon again. medium success!
    • Don't use that manifold. Please don't use that manifold. Sunk cost fallacy is not worth the later pain. None of these will be relevant to the change that will come from the different turbo and manifold. As in, the effect of the exhaust will be nil, regardless of what else is changed. And all the cam and fuel system stuff is not changing either way, so has no effect. The turbo and manifold (and to a small extent the wastegate)....big change.
    • Just wanted to say thank you for your input   my man (lead mechanic by trade) and I have done a heap of work as you can imagine just to make the hot side work with the dump pipe, stupid massive intake on turbo, trying to get the waste gate on was not fun.  I’m kinda getting to the point where I don’t know if I try and make this work and not throw all this cash and time away or do I scrap the lot and start again? the Apexi I’ve got was tuned for a few slight differences:   Tomei pon cams (mine are stock neo) Turbo smart 38mm external waste gate (mines 45mm replumbed) with stainless screamer pipe  3inch turbo back exhaust with high flow cat Sard 800cc top feed injectors Sard adjustable fuel pressure reg
