Thread: 6262 dyno Results and freeway vid p30

cut the 2.5 vband off and buy a 3'' and weld it on thats what i did with my 6262

Thats weird coheed, if you look at my post up there, there are multiple housings offered. The T3 in both the .63 and 82 show to be offered with the 2.5 and 3" while the t4's are all 3" This is for the 6262, the 6765 and above seem to all come standard with the 3"

I talked to the dealer and they said that the 3" is what I have. They just measure from the OD of the flange. Not the ID like the garretts. They call the T4 turbos a 3 5/8" V band, which is really just a "real" 3" vband.

Doesn't look like much options, but it is cheaper to leave the turbo alone and change the downpipe. Not a big deal to change the downpipe, as any muffler shop could really do it.

My turbo is a true 3" but I have the v-band in v-band out back housing.

did you have to modify it? When I talked to precision they said they don't offer the 3 5/8" in the T3 flanged turbos, and they list the Vband in/out housings at 3" as well. The flange they design for it is designed for a 3" exhaust pipe, but the connection is smaller.

I guess the Vband they make for it is designed for a 3" downpipe to "slip" over the vband and get welded in place. It is weird but that's how it is. I cannot find ANYONE online that sells a normal Garrett-style 3" Vband.

Not a huge deal though. I'll get it situated. I just have to buy Precision's flange kit. Which set me back almost $100 shipped to get here fast.

In the future, depending on how this works, I may be trying some other things.

I have a manifold design that is stuck in my brain that I'd like to give a shot. If it happens, I'll be selling my twin-scroll stuff and going Vband in/out.

well i bought a 2.5 to 3" v band reducer off ebay and cut off the 3'' side and welded it on the the turbo it came out like this

That looks really good.

I am going to work on the intercooler piping. I'll take my downpipe to the shop saturday and see what we can do with it.

I didn't have to do anything. All of the v-band in/out back housings are 3" out. That's why I mentioned getting that housing to u earlier in the thread. It will still perform good. I was told the v-band in/out housings flow better.

Ok, well the turbo is officially bolted on. Oil lines are hooked up, and it is bolted to the manifold. I deleted the coolant lines which took all of 2 min. And now I have to re-think my intercooler situation to get it to fit.

But it feels good to have it on. It looks complete, even though the stupid dp doesn't fit. GRRRRR!

Dayum this thing spins! the compressor blades feel so thin, I really gotta run a nice air intake setup on this thing. Suck in a bug, and these blades are toast! They feel like tin foil lol. Soooo thin.

I am going to take the downpipe in on saturday to get it welded up. Also, I am going to take in the intercooler and see if I can have another 90* welded on it to replace the 45* that it currently has.

I am going to do everything I can to get this done this weekend. I wanna drive it!

They may be thin but they are very very strong. You should be fine with it open in your area
