GT2871 AR .86 for 1.6. Keep or return?
I got a good deal on a China GT2871 with a .64 AR hot side for my 1.6. Unfortunately when I got the new turbo, it had a .86 AR hot side instead of the .64 AR it was listed as. The turbo is on the big side for my 1.6. Do you guys think I should try to return the .86 AR for a .64 AR or try it out. My current setup is a T28, megasquirt, and injectors. Runs good. Looking to upsize my turbo but not have massive turbo lag. Not my daily driver.
Thanks, Del |
It will not spool well in the slightest.

The turbo I have now has a .86 AR hot side and a .42 AR cold side. Not sure of the wheel sizes. Feels a little laggy but doesn't run out of boost. |
Would you be interested in a Twisted motion gt2871 with better specs?

and your 2871 is not any better at all |
You need a 2560.

I guess it depends on his definition of "lag".
but I'd agree with Ryan that anything past a 2560 on a 1.6 is going to be laggy chinachargers especially so since they tend to come on really lazy |
Noted. And why so serious? But in theory shouldn't it be since it has the AR number he was looking for?

Because a 2871 on a 1.6 is a stupid idea and will spool horribly. No AR will fix that.
|
Not that serious, just don't like opening the "new threads" to see you offering your stuff to everyone and their mother.
As for the last part: it might be a teensy bit quicker to spool than his current one, but likely won't make any difference at all since that's not his main problem. Like Lars said |

Sorry about that lol I changed my setup up and realized I'm sitting on quite a few extra parts. And wandered out of the WTB section when exploring the forum.
And I agree with you guys on going with the smaller turbo I thought I wanted bigger power then the GT2554 gave me but 2 months into the 2871 and Im learning power definately is nice but spool was more important to me. Just didn't know what OPs goal with the car was

Thanks guys and thanks for not roasting me on my first post. GT2560 it will be. It's actually going in a project car that is hopefully several hundred pounds lighter than a stock Miata. should be fun. Almost done. I'm picking up the chassis and body panels from the powdercoater tomorrow. Here are a few pictures of what was one of my Miatas. These are pre Powdercoat, bare metal. |
Wasn't there a user on here that ran a 2871r on his 1.6 powered RX7? Anyways his peak hp was pretty crazy (I think it was a relatively stock motor?), but about 2k of useable powerband before redline.

The 2560R is a far better choice. :party: |
Greg's 2554r with the billet wheel did some impressive numbers as well.
Just playing devils advocate :party: |
is your current t28 a ball bearing unit? From my understanding, a 2560 is a t28? 2560s/t28 journal bearing and 2560r/t28r ball bearing?
