I want something with a nice spool, ATLEAST full spool by 3500 RPM. This is going on my Miata & I have a 6500rpm redline. I do not want to exceed 12 PSI on the turbo & want to make right around 250whp. Stock mazdaspeed 1.8 engine. Not many guys in the mazda forums know much about turbo's & being a honda guy, I figure i'd ask here.

I personally was thinking a T3/T04E, 50 trim .48 a/r ... or

honestly there is about 50-100 different turbo's you could choose from, if budget allows a gt28rs would be nice.

I have considered the GT28RS, but im wanting to go with something cheaper. I dont want a ball bearing.

on a b16 pig rich and 6 psi i made 235. i mean like 150miles to a tank rich. (6 years ago bad chip from ard performance with my swap and an fmu.)

that was with a straight t04b with a drag kit.

im guessing that was on a dynapack cause thats way too high to be whp. im only saying that cause most drag kit set ups ive seen, even tuned at 6-7psi cant break 240bhp

good till 400whp?
If i were you, I'd go smaller. something that'll support 300whp, that way you'll have better boost repsonse, 250whp will be in it's efficiency range and you'll still have room to play. especially if you want full boost by 3.5k.
also, why have you set a boost limit? psi doesn't break stuff, horsepower does.if you choose a smaller turbo it'll take more boost.

as in a t3/t67 or the big kahuna? or is there another t3/to4r i don't know of.

t3b18b

yeah the big kahuna. its a bad *** turbo. my buddy had one on his gsr. and wow. i have a straight t3 50trim on my ls and i get full boost at like 3200 and i make power until redline. 230/195. this is at like 9.5 psi so just to give you an idea. and the ls head doesnt flow very well.

i'd say it's a liiiiiiiittle bit big for someone shooting for only 250whp and full boost by 3.5k. badass turbo nonetheless, but wouldn't be my first choice at all for this app..
