[Exogy1]

who makes em, and for how much....i found some for a really nice price...and ill pick em up this weekend if i can get manifolds for decent as well...lemme know asap please

dynamic racing has a kit - you might be able to get just the manifolds. If I do a turbo upgrade those will be the ones I go with. Good luck

yup DR has t3/t4 manifolds

other than that you would go with DNP which is alot more expensive

u lookn to do the GT2871r's? I wonder which exhaust a/r it comes with? .48 ?

The DR kit hot side is .86 I believe. DR kit is the only kit that uses T3 flange manifold instead of the common T25/T28 flange. I would go with .63 on the hot side for those turbos with our cars.

quicker spool perhaps ?
the smaller a/r is good for ~330whp on just one of them (2.0liter)

The 63 hot side will spool quicker than the 81 but the trade off will be in top end which the 81 will win. In the end of the day what are going to be goals for the car? I won't personally go with the 81 hot side unless I have the breathing mods behind to it such as Stage 3 heads, cams, cam gears, upgraded valve train, intake manifold, and TB to take full advantage of wider power band the 81 will give you.
