So after waiting a week in the mail for a T25 downpipe flange for my turbo, and finding that it doesn't fit, I'm once again relying on someones expertise to help me find out where I can get one of these. It's a small garrett T25 turbo off of a 91 Nissan 300ZX twin turbo. Any idea who carries these?
This is the flange I ordered:

Fits All GT25 GT28 GT-RS & Nissan Silvia S13,S14,S15 OE Garrett Turbos. I figured the S13 turbo was the same as the 300zx.

Search the nicoclub forums for one. That's where I found mine.

You might try contacting Seb or Greg at Specialty-Z

I got mine off eBay... Worked well for me.

Thanks for link. I emailed them.

Which one did you buy? What was the description.

It came with the T25 manifold flange, Downpipe flange, and Compressor outlet flange. Let see if I can find where I got it as it was a LONG time ago...

Granted mine was for the S13 Redtop T25... What didn't fit when you got the SR set?

Edit: Meant to edit my previous post... FAIL!

It looks like for the 300zx turbo, they changed the flange. It's a 4 stud mount. I'll take a picture and post it up.

That would help... I read where some guy had to buy a pre-cat for the Z32TT and then hack the flange off to make his downpipe that way. Might be worth a shot to check your local junk yards for one.

I was in the same predicament as you are now in. My turbo came off of a Nissan Twin turbo catalytic converter side of the setup. I had to have a flange made for me and then a downpipe fabricated by a local shop.

I was able to get a downpipe from a Twin turbo but it was made of cast, not too easy to weld to, so not an option to cut the flange off.

This is what I found on the internet before getting a custom made flange. I thought about contacting them to see if they could just sell me a flange, but I didn't. Their prices on the downpipes are pricey.

I ended up getting everything custom made through a local shop called:

Thanks for all the links folks. I got a hold of Greg at Specialty Z (Specialty-Z), and got a reply almost right away. They have the proper flanges (divorced gas too), and they're not that expensive. So I'm ordering the flange there, and then the fabrication is the easy part, I know a wicked stainless welder

Specialty Z is a great place with good support... My buddy has a Z32TT and has had nothing but praise for them! Can't believe I didn't think to contact them about this. Glad you found what you need though!

Glad that worked out for you. I had TTZs for 6 years and Greg was always very helpful. I got to meet him in person at a Z meet out in LA, and he was just as nice in person, and his personal cars were amazing.

I have a 3" downpipe with the proper flange made of SS that I could sell if you want it.
