Thank you so much for the help Stinger. I think I finally "almost" have this stuff down. Here's a T04E 57 trim compressor map that I plotted. . The t61 compressor looked to be a really nice fit for 25-30 psi with full boost at 4000rpm. But since it's a street car, I would like the boost to come on around 3000. Time to look for a new turbo. Thanks again!!!

Yeah, you see the "issue" some 2.3T setups have with the 57 trim, it gets closer or goes left of the surge line, causing the turbo to surge as the turbo reaches full boost.
A T04E 50 trim has a much more favorable surge line, can produce ~35psi, and will support about 420rwhp on a 2.3T engine. Paired with a stg 3 .63 a/r exhaust housing, it will reach full boost around 3100 on a 2.3 capable of 350+rwhp.

The photos of your progress are great, nice work! I'm a little confused on one item, your location? The post address is Fort Stockton, TX but, the tags are from PA?

How do you think a Precision 6262 Cea would do on the 2.3? I know there's no compressor maps available, but a few other 2.3 guys are running them with good results.

It's fine if you're looking to make as much power as the 6262 supports. It will spool slower than the smaller 50 trim mentioned above though.

Well I'd like to do a street tune for 375whp, and a race gas tune for 465whp, so I think the to4e 50 trim would be a bit small. I cant seem to find many compressor maps with a favorable surge line for the 2.3, but maybe some of my calculations are still off. Would you be able to suggest a turbo that can get me to my goals, and still be pretty efficient?

The 6262 is fine for those goals.

Do you think I can get away with using a .63 A/r exhaust housing and not have surge issues?

I think that turbo has a stg 5 exhaust wheel (my 63mm does) so it shouldn't be an issue. Bo wouldn't sell it if it wasn't 2.3 compatible.

Well, I'm not buying the turbo from Bo, and I haven't had the chance to talk to him about it to see what he thinks. I just wanted to ask you're opinion about it, as I'm having a hard time finding a turbo that will be somewhat efficient at the power levels I want to produce.

It's certainly a bit large for your goals (680hp capable) but it's highly efficient. You can always get the anti-surge housing for a little extra protection, or use electronic boost control to taper in the boost a bit slower to keep it from surging if you do find it to be an issue. It shouldn't be though.
