GT2871R T3 vs T25

[theskuh]

looking at some manifolds it seems like there is better cast options with a t3 flange.

Is a t3 inlet too big for a GT2871R? Will it cause boost to come on later?

[Don Supreme]

T3 ftw! - trust me.

T3 hands down. Boost will come a few hundred rpms later but the power won't fall off at all. The t3 hot side is much easier to work with as well since you can easily get to all the bolts to the manifold. The t25 is a tight fit.

[theskuh]

No doubt. but what AR the .48?

Looking over the web for stuff and found a site sying the t3 .64 will act like a t25 .86

[Poopie]

get the .63. The combo makes a great street set up. Still has a pretty early spool and great top end.

My rule of thumb is if you are already trying to use the smallest hot side you can, then your compressor is already too large.

I didn't think GT2871Rs come in a T3 flange

Garrett's website doesn't show any T3s...

That must be something custom that ATP does then.

[Don Supreme]

They do come with a t3 (not the usual setup, but better IMHO).

Amen. Amen. A-fucking-men!!!!

What manifold suppliers are you looking at

[theskuh]

I was looking at the SPA cast one. It sits the turbo high. Still in the way preplanning stages for sure.

[sean1.8t]

if you change to any other manifold you're going to have to redo the exhaust setup. even if get an adapter plate, you probably will

[t1demont1]

Just get the spa, its a beauty.

[onemoremile]

Spa T3 top mount with a 2871 or 3071. That is a great plan.

[TQMB5]

i couldnt find a spa manifold in t25 flange, anyone got a link?

I don't think one exists. He was going to run a 2871r with t3 housing.

They have one with T25 but it isn't the one that bassed runs.

[Squarrl]

The guy on ebay bob something is the dealer. He has the T25 for $325 shipped to Canada last time I asked.

[Wizard-of-OD]

Not for the SPA manifold he wants.

He wants this one:

[bassed]

TM A 04 is what he wants for the top mouting T3 flange.

[theskuh]

issam when is the downpipe going to be available? Will it have the high flow cat option? cost?
