hey guys am ordering a 3'' v band flange for my turbo but i read somewhere that universal v band flanges don't fit the ex housing ans that a precision v band flange is needed..

can any one confirm this to be true?

 

i dont think this is true.. i just tried the universal v band clamp on my 67-68 and it fit like a glove.. just make sure you have the right size v-band clamp i guess

 

thaks alot..was worried for a moment.

 

you need 2.5"

 

ATP sells flanges that have always fit up to anything ive have. Ive had 2.5, 3" and 4" flanges from there, all fit perfect. I had an ebay flange once and i had to grind it down because it was way to big. Probably an 1/8th inch larger on the diameter. When i tightened the clamp tight to the exhaust flange it wouldnt even grip the turbine housing. It was a pain. Do it right and get a good, well made flange. Dont go with eBay.

 

actually mine measure 3''...just wanted to make sure though

 

the t3's use 2.5" and the t4's use 3". universals will work fine, made a downpipe for one yesterday. the flanges PTE sells for the T4 can use a t3 tube (fits like crap) or a 3.5" tube that fits well. their flanges are pretty pricey

 

that makes sense. mine is definitely 2.5" and its t3. i did buy an atp stainless flange that allows a 3" pipe to be welded to the 2.5" flange without a transition. very convenient

 

For the t3 housing you have to use the "2.5" atp clamp and flange (even though its actually a bit larger than 2.5). I had to buy a clamp from them but the flange I got from Precision already so I didnt have to mess with buying that part.

The T4 housings use the "3.0" atp clamp and flange.

guess i made a lucky choice haha

 

wow, perfect timing for this thread! hahaha i was just shopping for v-band flange for my 6262 t3, almost ordered the ebay flange.

i was told that the t3 was 3" v-band but i guess not.

 

They call it a 2.5" on ATP and alot of other sites but it is a bit larger, its just shy of a 3" really.

 

not 2.5" not 3" i'am running the 6262 sp it's 2.75 vband i ordered a dp from maxworz 3" when i got me it was to big i called precision they told me 2.75 v band,hence my manifold had to get cut and reweld the 2.75 vband worked like a glove.

hope this helps

 

also mine is a t3



ps. for the record the 6262 is to me the best turbo ive ever used.

 

so the atp 2.5" flange/clamp is actually the 2.75 that the 6262 needs?

 

I ordered and am using this ATP vband clamp (as I linked above) for my t3 6265... it is indeed the one they call 2.5" despite it being actually slightly larger size. Fits perfect.

This is the matching flange to it per ATP, although I have not used this one since I already had one from Precision that shipped with my turbo.

I bought the genuine Precision flange for my 6265, and I was glad I did. It is a super nice piece that 3" tube fits over like a glove, with a nice overlap for easy welding by a hack like me. For an extra 10 bucks or whatever it may have been, it was worth it!

Oh, I just looked at that link to ATP, and I think the Precision one was cheaper than that by quite a bit. Now I'm really glad I chose that option.

 

i order those from ATP also, fits perfect on my 6262 with .82 v-band t3.

 

Correct.

 

is atp still the only option on this, I put one flange and one clamp shipped is 70 bucks

and they told me they won't even offer to do me a modular pipe they sell 3" but with the 2.5 flanges, said no one off's

like this but with the needed flanges for the 6262

No Limit Motorsports in the Sponsor's Only section also carries the "2.5 inch" flange & clamp assembly, that's where I ordered mine from for my T3 6262.

 

My 6262 uses a 3in vband I got the vband clamp and weld on piece from RC it would accommodate a 2.5 or 3in dp. I remember talking to Danz and his was a 2.5 kind of wierd this is a t3 82

 

atp now offers the modular the way I need

 

my 6262 has a 2.5inch v-band.

i think they are available with 3 inch and 2.5inch. i would have preferred 3in but oh well.
