noone:dang: can help

I think the phatshaft 62 would be a good choice. From what I've been hearing about ATS's warranty issues, I would stay away from them.

ATS = warranty problems... had a friend go through that once. I swore I would never buy anything purple

I wouldn't go with the 62 unless your planning larger injectors int he future I would do a S300G

do you mean larger than my 370 marines i have right now

Yes

Sent with a Droid RAZR in one hand and 14,000 volts in the other.

5x.012 is a good match for the 62mm. the ats3000 is closer to the s300g 57mm and is kind of expensive for not being a wastegated turbo.

5x.013 and a 63mm is a good match too.

with your marine 370 you will want to keep timing under 16.5* so you do not spray out of the bowl

I would go with the 62/65/12 with the mods you have , I think with a 71/14 you would have a hard time spooling it, you can also turn the boost elbow down on it if you start exceeding 35-40psi, just my 0.02

I' m looking into the S300GX from airworks .. $1080.00 .... will support upto 400 hp .. they unfortunatly could not give the exact sizes and or dimentions but the airworks web page does have the map for these turbo's .... fyi ...

It is the same thing as a super B turbo but it does not have the adjustable wastegatge and you may need to adjust the actuator rod by bending it so it will clear the oil drain line.

specs are 57/65/14 flows 61lbs. great for 400hp. The BD one is better as it has some upgrades to it.
