thats like saying how much hp can i hold in my hand. There are alot of variances dude. to list them all you would need to spends hours upon hours searching and reading, etc. That being said i would get a t3s60 it seems to be a very nice turbo with decent spool time and good breathing charecteristics. Wich car do you have? you might pick up a mitsu kit like me, or maybe a 16g and get corky to make you some Manifold and DP to go with it shouldnt be alot more than a t3 or anything else. A greddy will hit that and up to 280 without realy kiling the turbo.

 

Not really, my question was more like, What's the most power you've seen done on a T25 for the miata? you could have said.. oh the most i've seen so far is 267rwhp.

 

If i ran a garret turbo i might.
