turbos 3071r vs 3076r

[mjrstar]

Well i have a t3 flanged manifold and i'm on the lookout for a new turbo, i think i have narrowed it down to either a 3071 or 3076.
looking at probably a .63 exh housing,

does anyone have any actual experience with these turbos.

I will be looking to make the same power level as my last plain bearing turbo (245kw atw).

not too worried about lag as it is a light car but also i have no need for more power( yes you did read that correctly) any +ves or -ves with these turbos would be of great help.

engine is stock 2 litre 1ggte with only external mods ecu, fueling, manifolds, i/c etc...

[Dell'Orto]

Lith has a 3076 on his car, he'll fill you in more. I think it'd be a bit big for a 2 litre myself.

[matt dunn]

I run a gt3076r on my 1800.

[DRFTIN]

if you dont want more power why go for a big turbo?
i've got a gt2871r on my sr making 260kw@wheels and it probably comes in 500-1000rpm earlier than a 3076

im guessing matt runs that turbo to get the most out of the sports saloons class rules? otherwise its really overkill i think

as for the 2871 i'd prefer to stay t3 flange as it'll be a mission getting 7 pipes to fit in to a t2 flange.
what other mode does the engine have to make 260kw and at what boost level?

[DRFTIN]

i just used my turbo as en example, i think they can be had in t3 flange anyway? but there must be a similar turbo commonly available in t3 flange?
my engine has just the basic stuff to get that, injectors bigger afm and tune
i have got mild cams too, so i get that power at 16psi, other guys run standard cams and 18-20psi to get the same power

You should talk to me and get a masterpower turbo.
They do garret equivalents. (wheels sizing etc)

alot more affordable than a garrett.

well no - I believe they're more offordable than a garrett......once......

[Bazda]

what do u mean by that?

[cat007]

well - aren't they made of inferior materials?

Inferior? I dont know about that..

Garrett is a good brand, dont get me wrong! but I certainly wouldnt pay the money for a garrett when I can get a master power turbo to produce the same results at a much less cost. + you can rebuild a master power turbo. Once a garrett core dies you have to buy a whole new core which is around $800+gst.

I know a few guys who have had their garretts fail without any reason. And it was just too $ to rebuild it.

I rate Master power power turbos highly! and have been running one on my car now with great results .

Garrett plain bearing turbos are every bit as cheaply rebuildable as Master Power. Actually most people who I know of who have blown their Master Power turbos have either had them rebuilt with Garrett T-series parts, or replaced them with genuine Garrett equivalents.

I reckon a GT3071R and more so a GT3076R are overkill for your target, especially on a 2litre. You can get a GT2871R with a T3 flange these days, they will make the power you are after with much better response and boost threshold.

Just checking - but I don't understand what you mean the master power turbo cores can be rebuilt but the garrett ones cant???

I can understand that you wouldn't want to buy a garrett for the initial purchase price, and then the possible repair price.

I guess I've just had it drummed into me to not by cheap turbo's - but maybe the master power ones are different to the regular "chinese special" you find on ebay/trademe?

interesting i didn't know the 2871 came with a T3, i think the little bit of extra lag may prevent wheelspin which is failry prevalent in my car..
there are so many varaying opinions on what to do but i guess it all just comes down to personal preferance. i guess the cheapest most sensible option is to rebuild my old one as i was happy enough with it... it just seems like a good opportunity to go to newer technoligy for not a lot more cash outlay.
the other side of the coin is it might be handy to have a bit more flow left if there was ever the urge to build a better engine...

[molex]

It seems to me that more turbo lag as a cure for wheelspin seems a bit backwards, if the goal is to go as fast as possible surely you'd be wanting boost (and thus torque) across the widest rev range possible? If you can attain your power goals (and it certainly sounds like you can) with a smaller turbo then I'd say go for it.

Master power turbos sound like a pretty good deal to me, interchangeability of parts and ability to rebuild appeals.

If wheelspin is a problem, lift right foot?

[cat007]

torque = wheelspin

lag = lack of torque

by the time the HP comes in higher in the rev range, you're already going to fast for the wheels to spin

Im talking about the Garrett ball bearing series.

Master Power is def not from China. They are made in Brasil and have been making turbos for years!!! Since 1970s!

Its a bit of a shame that alot of people think its just another cheap chinese turbo. Even some guy at the drags asked me the same question!

[Dell'Orto]

Weren't there a bunch of Master Power turbos made in China? I do recall a few years back some nasty failures from Master Power turbos.
