Hi, im currently looking to upgrade my T25 and ive got the opportunity to get a real bargain on a GT3071 which i understand has the T25 flange
My concern is though what sort of lag would a turbo of this size bring and would i be safe running 12psi on this turbo on a stock motor?? i will have to upgrade my fueling system and get my megasquirt remapped i know!!
any advice would be greatly appreciated![](https://www.miataturbo.net/images/smilies/smile.gif)
thanks

* These wastegated versions of the GT3071R use specially-modified GT30 turbine wheels for use in the T25-style turbine housing
* The GT3071R wastegated units are the highest-flowing ball-bearing turbochargers in our range employing the "T25"-style wastegated turbine housing

There are also some nice v-band outlet and externally wastegated t25 housings available through ATPTurbo.

a 3071 is a pretty desirable turbo. i'll bet you could swap somebody for a 2860 (maybe even this guy http://forums.nicoclub.com/fs-garret...o-t505829.html) plus cash.
ou should be able to pick up a ball bearing gt28 (from a nissan s15). check the nissan forums.

I would run less than 12psi on a 3071. You're liable to make a lot of power, even at low boost levels, and you don't want to push a factory longblock past ~250whp for any appreciable amount of time.
If you have plans to build a motor for the car down the road, pick it up and keep the boost low. If you never want to build a motor, I would keep your T25.

you will need to "remap"? I hope you're not talking about the stock ECU. The stock ECU has no way of sensing boost, and I sure as hell know you can't "remap" it. With the amount most shops charge, it would be cheaper to just buy an MS anyways.

lol I wouldn't imagine it hitting full boost any earlier than 5k.
But when it does, OH BOY will it feel good.
And its not like the car will be completely dead up to that point. just a couple psi from that turbo at 3-4k will already generate some decent grunt
If you want to rape face the power is just an upshift away
