Check out www.turbochargedpower.com that`s where I got my setup, lot`s of big power mustangs with stock blocks

You would be spending too much dough and going through too much hassle with turbos that size to make such average gains 5point. If you want those numbers just go single turbo. IMHO.

a pair of .63ar T3's will support around 580+ hp I believe...enough power to split a stock block

Aaaaaand... Phenomenal torque. The low end would be amazing, I dont understand why anyone would NOT recommend doing this. I only went single because I didnt want to worry about the IC plumbing and a blow through MAF. If I had my choice i would have gone twins.

I should get some pretty good bottom end grunt...I'm planning on using a pair of t3's with a .48 housing. It won't pull much past 5k but it's a street car...I'd rather have them spool up quickly.

Stang Seller

Absolutely, those will still pull great and make tons of low end. You would be best off running 3.27s or 3.08s with those small turbos, and make sure you've got some nice rear suspension to hook up all that grunt . Even the .63's will spool up very quickly, you'd probably have full boost by 2700-2900RPM with those depending on your combo. Turbo's ruuuuuuuuuuuule!!!

I'm probably going to start out with my 2.73's...I can always upgrade later. I should see full boost around 2300- 2500 and top out around 5200.

I mentioned the single option for these reasons. You eliminate the cost of 1 wastegate, 1 bov, 1 oil line, 1 IC core plus end tank, 1 pipe, etc. Turbo torque is legendary but useless in a free wheelin 5.0. Like Stang Seller said I would do rear end work to compliment your set up. Small twins usually compliment a motor that lacks low end torque. This does not include the 5.0. So as you said some will offset this issue by changing the gear, thus offsetting some of your gains. See where I'm going with this. If you want 400-500hp get a decent sized single turbo put some dough in your pocket and get it too spool throughout the higher rpm scale. With a little rear end work you will pull all the way to red line and maximize your gains. I still love a twin set up but if you are budget conscious I would still consider the above mentioned.

Trust me, I'm crazy! Lol.

Using a pair of turbocoupe T3 turbo's, you dont have to buy an extra wastegate as they come wastegated. You only run a single intercooler. Sure there's more piping, but I'm sure Mark here is leaning towards a JYTT setup which will probably cost just as much if not less than a comparable single setup. And low end torque will be higher, although you wont hit the same top end power as a proper sized single. You're right about the gearing in a sense, but the reason for such a high gear is not to offset the power but to increase the "power band" to the tires. If you're running out of steam at 5000RPM then why run a short gear? I know where you're coming from and if we were talking a new twin setup I would totally agree. But a simple JYTT setup would allways be pretty darn cheap!

Maybe I should have read closer. I know he mentioned JYturbo but I did not realize he was using turbocoupe turbos, my bad. Yes T3's normally come with internal wastegates, and that usually works for those units. I myself would never do it. Thats why a lot of guys weld the internal wastegates closed and choose a more reliable and easily tuneable exterior unit. As far as intercooler goes I said IC, meaning Intercooler Cores. Sorry for the mix up. Gearing does not change your power band. Gearing only affects speed in relation to engine rpm and tire revolutions. Not power band. Stang Seller I love your passion for turbos, maybe we will meet some time at a show and continue chatting about various turbo techniques.
