Well, as the saying goes... you gotta pay to play. EVERYTHING is a risk, so know that before you mod it, otherwise, no sympathy or whining allowed when you blow up.

i still think a 28 tuned to 20 psi and my driving habits, which are severe btw, will survive. On a 35R, i guarantee i would blow.

so does this mean dog man wants to help me install in a few weeks???

:Banane35:


:stupido2:

Not with pot in your property line, no.

everyone knows i just smoke all of bab`s weed.. haha, so looks like your helpin me? haha...

seriously though if you were to come over and drink all the beer in the fridge and guide me a bit. i would be stoked and you could have some beer. haha

Im sure that can be arranged.

I'm surviving so far at 20psi since Julyish. Been wondering about 22~24psi. But I might wait till I get some rods first. Winter is coming, so I won't be getting on it much. Cold asphalt and summer tires don't mix. I think the 2871r is great for those who want to replace the stock turbo, but are not looking to make big big drag car power.

I also agree with Haltech on the cam issue. I'm sure the GT30 and GT35 series are great, and makes tons of power. But they can't be used to it's full potential until some cams come out to support a different power band to make use of it's spool time, rpm, power, etc, etc.

ah! the never ending battle between the 2871 and the 3071........deja vu from my SRT days. Technology has come a long way and that 2871 can produce 350-380whp on the srt easily, and im guessing thats not too far from us either. I've seen plenty of well tuned srt's running both turbos and from a low punch, that 2871 easily holds off the bigger turbo up until the 130-140ish mph range when the 3071 starts breathing. our problem ofcourse with that would be spool but it would make for one mean ass ms3 running that turbo if we had fuel under control.

I'm sold on the 3076. I want the later spool and the possibility of going over 400whp at some point. Plus that turbo will hit and power numbers I want at a moderate amount of boost.

My opinion: Because too many people are caught up in "bigger is better" logic.

Probably 95% of the people on this forum have no need of anything bigger than the 28, but most with aftermarket turbos have 30's or 35's.

The smaller turbo will be more streetable (spool earlier), at the expense of max power potential naturally. There is always a tradeoff.

But seriously, how many people are really planing for the supporting mods likely required beyond the ~380whp the 28 can supply? My guess isn't too many.

I understand that people like Laloosh and Whoosh that wish to push the envelope and don't care much about low/mid RPM characteristics might see the 28 as a silly saladshooter, but the reality is that it would be great for most people.

It is all about individual goals. I personally would like to end up in the ~320-350whp range reliably without breaking the bank. After everyone does the R&D over the next year or two, I expect to be there.

:veryhappy:

You also have to be able to recognize problems before they cause catastrophes...

lol dreaming a little too big there.:nutkick:

Anyway I just helped my buddy install a 28 on his speed3. This thing is no comparison to the stock turbo the 28 is much better then the stock turbo. I agree with many others in this post that without building the motor this turbo is way more then the stock motor can handle. If you cant build the motor or dont want to then why not get this turbo? spools fast gets you the power when you want it.
:wiggle:

I appreciate the input here. Looks like the Gt2871R would be the ideal turbo for myself.

my gt2871r is now on...
DD is nice.. you can stay outta boost if you like or let the powah come out.
go for it.

Mine is on too...gonna start driving it tomorrow after 5 weeks of downtime. I'm excited. xD

Hope you guys give us some more input soon.

^^^+1

Can't wait to see some dyno numbers as well as longevity reports.

cant wait to put it back on ...fucken ceramic coat DP take forever to finish LOL

Yeah my ceramic coated mani took 3 weeks to get back to me lol

now we got a bunch of gt28 MS6's.

horaaay!

honestly what would happen if i just bolted it on and used the cobb beta map with it?? would it run ok? would it boost the same, higher, lower????

well.... your going to want to tune it if your going to run WOT... shit will likely knock and scream bad numbers at you.

also, i might consider a MBC, unless you want to change all your boost settings on ATR to compensate for the WG spring pressure... (which varies)

t3 turbooo all the way

atenza freak or MPS?
me confused?
t3= easier said than done.

will a gt2871 bolt on p&p to the stock exhaust manifold? and what about the downpipe? could a stock like dp, like cp-e or whatever, be reused for it?

if so, the oil support, inlet and hot pipe were the only things to care about for the installation or what?

if ur gonna buy a mazdaspeed specific kit from atp then it's pretty much pnp.

Yes BUT. The issue with the ATP turbos flanged for our cars is that they boost creep like mother fuckers. You either need to do some porting to run the IWG or better yet use an EWG. Besides that it's a straight swap.

to do some porting where?

but going with an ewg meaned to use an aftermarket exhaust manifold and i couldnt ruse my cp-e dp. am i right?

Wrong. First off the manifold has nothing to do with DP except that both connect to the turbo. Secondly, you certainly can run a CPE DP, aftermarket mani with EWG, and a gt871r (that's exactly what I'm running...CPE DP + DNP mani w/ EWG + GT2871r).

I think it was P3 that at some point opted to fight the boost creep issue by porting out the IWG with some sort of success. IMO the right way to do it is to just go the EWG route.

thank u man!

but i am always a lil confused about the shortcuts u all use. i have to excuse.

whats a "dnp" manifold? is that the brand???
