Anyone know where I might find one of these? Its not quite a T25 flange, two of the bolts do not line up nor is it the same as a GT20 flange.

I'm talking about the downpipe flange...

 

300Z turbo?

Damnit I have no idea what I'm talking about

 

I've heard the 2nd gen 300ZX turbos referred to as T22s but I don't know if there is any similarity with what I have or not. I bought a new GT2252 a few months back from PTE. If it is the same as the 300ZX where the hell can I find one of those flanges?

I tried one of the T25 flanges with two sets of bolt holes in it with no luck, I've seen them with slotted holes and I'd like to give that a shot but I can't seen to find anyone that sells them. I can have the flange made locally but I really want to avoid that hassle.

 

Naw, I'm not saying it's the same as the 300Z, just curious. I would give PTE a call and see if they can point you in the right direction.

 

make one, or have a machine shop make you one. If you can get a template or draw a template off of the turbo it should be easy.

 

True. Having the turbo present will make it much easier.

 

yes its a t2 flange. and yes the 300zx uses that flange its a t25 variant with a 4 bolt pattern. i have yet to find one :( i think i did find one on atpturbo.com but its a cast iron peice and its i think ment to be an integrated w/g.

let me see if i can find the link. but thats the closest i have found to anaything for it. what i have had to do it use a t25 flange and move two of the holes and chop off the ones i am no longer using. :( not happy

 

Actually that sounds like the OTHER GT22 flange.


This is the one that I have.

Its so close to a T25 I've had to photocopy both housings and overlay them to convince someone that there was a difference.

 

wtf cant say i have seen that bottom one before. i hate all flanges in this series. should have just gotton a t3 or somthing so much easier

 

Yeah, but the compressor map is perfect.
