GT2876 on a 105 1hz

[Feass]

Hey

Just wondering if anyone else has strapped one of these on a 105 1hz?


Cheers

[ledgend80]

mate have a look at z()ltan's thread in the members area or pm him

[Z()LTAN]

u cheeky bastard

He knows my build, i was the one who convinced him to put this turbo on his car lol.

He just wants to know if hes the only one with a 2876r on a 105 series Cruiser.

[ledgend80]

duck put one on his 80 series 1hz

[Feass]

Yeah zoltan and i have had many chats about the setup, he was the one that inspired the idea just wondering if there are any one any 105's around the place.

[rowenb]

What are these turbo's like compared to standard factory ones ie. response, low down boost ect?

[flyology]

I would be interested in some pictures of Garrett turbo set ups on cruisers... any one got pics to post??

[80's_delirious]

What are these turbo's like compared to standard factory ones ie. response, low down boost ect?

I'd be interested to know some figures too, ie how much boost at 1800rpm, 2000rpm, 2500rpm

edit: oops, double post. In case you cant tell, I am REALLY interested

[ledgend80]

my gt2871r makes 10 psi at 2300 rpm with no tune at all

[rowenb]

There sounds like so many variations of these garrets so what seems to be the standard? My mate has one on his 100 DX(don't know the no.), nothin special but it drives a dream.

[Z()LTAN]

Gt2876r

2psi @ idle (800rpm)
10psi @ 1200rpm
17psi @ 1700rpm
20psi @ 2100rpm
25psi @ 2500rpm

Keeps pulling to 4800rpm

This is 1st gear...

[Feass]

i got mine back today, got a gt2876 on a 105 1hz with 220 on the clock. i had a dts kit on it and i was piece of shit. this unit makes a shit load more power, earlier and stronger, on 7psi and a 3" than the dts did on 15psi....

need not say anymore.....

[flyology]

What turbo did the DTS kit have?

[fumduk3]

should be a mitsu td05..... the 1 on my 80 is piss poor (laggy) worse than an axt t3 on my otha 1

[duck]

yer i put one on my 80, makes 10 pound at 2000 RPM not max fuel but gets hot on long climbs coss of no cooler, will be putting more in when i get the cooler on.

mine has a 1HDT manafold with an adaptor flange made but Matt McInnes. all bolted up very well, here is some picks





and the flange made by matt

[matt.mcinnes]

Above Pic

Top left T25-T3
Top Right CT26-T25 as is Ducks
Bottom Left T3-T4
Bottom Right CT26-T3

All 14mm thick 3D CNC/CAD smooth blending radius between the flange faces.

Also have a CT20-T25 on the drawing board for 22R-TE I think it is.



Drop me a PM if you need one.

[fumduk3]

shit those adapters look nice wish id seen that t25 to t3 before i bought mine.

[Paul Smith]

hey guys just wondering how much is it costing you to put your own kit together, I am interested in turboing my 105 series but not sure what the outlay will be, also where are you getting your parts, the turbo mentioned what do they cost.

Paul

[Feass]

Turbo cost me about $1320
3" Exhaust with twin tips was $1250 bout a $1000 with single tip
Labor was about $1000

My fuel hasn't been touched from the previous DTS kit tune and i get a strong 7psi, EGT's stay below 500 aswell. Was towing about 2.4t yesterday and even under full load it was still under 500..

Shoot me a PM if you want to know more Paul.

Hi feass what was the main problem you were having with the DTS set up?
I have a HZJ105 with dts turbo which seems ok but would like to have a bit more, like we all do.

Matt

[Feass]

The only reason i really changed turbos is the TD05 DTS turbo shat itself... only 5 year old too. After investigating it more, i found it would cheaper and more reliable if i were to by a new turbo in the long term. Which then bought me to speak to Zoltan on this forum about his setup.. so then i just got that. He, naturally, runs lots more boost and has an unreal ICooler too..

[hdj105]

25psi @ 2500rpm
Keeps pulling to 4800rpm

Does it maintain that 25psi at 4000 - 4800rpm?

[Z()LTAN]

yep doesn't change at all.

Ive seen 5200 rpm a few times by accident when i get carried away.

Exhaust note and power never changes

Any idea how the GT2876 would compare to the GT2860 and GT2871 on a 1HZ?

From reading other comments, it seems like the smaller GT2860 might be a better choice to spool up lower in the limited rev range of the 1HZ.

[Z()LTAN]

The GT2876R , 71 and 60 all have the same turbine choices, the 76R is the only one with the huge .70 compressor ar, 4" inlet and 2.5" outlet. Thus flowing more air at lower revs, thus producing a quicker and more intense boost rise.

[SimonInAustralia]

I really don't know anything about them myself.

But from reading about them, I thought that a smaller AR would give faster spool up at lower revs...

http://www.turbobygarrett.com/turbobyga ... onyms.html

Turbine A/R - Turbine performance is greatly affected by changing the A/R of the housing. Turbine A/R is used to adjust the flow capacity of the turbine. Using a smaller A/R will increase the exhaust gas velocity into the turbine wheel, causing the wheel to spin faster at lower engine RPMs giving a quicker boost rise. This will also tend to increase exhaust backpressure and reduce the max power at high RPM. Conversely, using a larger A/R will lower exhaust gas velocity and delay boost rise, but the lower backpressure will give better high-RPM power. When deciding between A/R options, be realistic with the intended vehicle use and use the A/R to bias the performance toward the desired powerband.

Like Feass, I'd like better performance than my DTS setup is giving me, something that kicks in and pulls hard before 2000-2200 rpm like the DTS Mitsubishi TD05 does.

[Feass]

I spent loooots of time talking to Zoltan about heaps of different setups and it all came back to the 2876RS.. and i dont look back.

There is one hill that i could never get up in third, and because there is a tight bend at the bottom, you couldnt get more than 40kph run up, now i can hit it in third at 30kph and make it up with out an issue at all! the amout of torque increase is amazing. the TD05 may be good for a 2.0 petrol but not for a 4.2 diesel..

[SimonInAustralia]

I don't doubt that it goes great on Zoltan's truck, with big boost, intercooler (and possibly heavy right foot) like he has, I am just wondering if it is the best choice for a daily driver running less boost, with much more km's and looking for a little more longevity that what is required for a low km comp style truck.

From reading turbo definitions, it seems like a smaller AR is better for more boost quickly at lower revs.

Your setup seems to increase performance for you, over the standard DTS setup, but it could possibly have even less lag, and even better low rev performance, with a smaller AR turbo than what Zoltan chooses for his application.

It seems like it would be a tradeoff between low revs response/longevity and max power, but maybe someone like Zoltan is looking for max power and high revs, and maybe not necessarily considering low rev performance/lag.

I don't know myself, just asking the questions, which I suppose can only be really answered by someone that really knows what they are talking about in turbo theory, or has actually compared the options on the same engine.

The definitions seem to suggest that smaller AR is better for low revs.

It seems to make sense, less air required to get the turbo spinning, which is what you have at lower revs, but then a greater restriction at higher revs, for less maximum power.
