Default Turbo downpipe flange, where to find for td04 9b?

I had bought a 14b/16g flange thinking it would be the same as it looks similar, but turns out the flange is quite a bit smaller. Any ideas on where I can find the correct flange. I've done quite a bit of searching. Turbo is from a 3000gt (one of the pair) for my 1st gen crx 1.5. The only thing I've found is from time to time a precat/O2 housing comes up for grabs on fleabay. Usually they go for about $50. The funny part is that OBX and others make precat delete pipes that use the exact flange I need. Any insiders get me one?

Im planing on doing a similar setup on a buddies crx except its gonna be a twin 9b. but i can get you a good price on some front manifolds that have the flange on them and some o2 pipes but probaly not the flanges them self (they are rare to find). they would have to be cut off though. but thats fro 3si.org or local 3s group.

LMK if interested and i can give you some peoples emails and see if you can work something out with them

She's standing still at the moment while I search my *** off for this part. The link to the part in post #4 somehow isn't the right flange for the turbo outlet. The shape and bolt pattern is the same as a 14b, but the flange size is about 30% smaller. Here's the option I have on the table, but I'm too cheap to want to spring for this. It's actually a pair which would have to be re-welded anyhow.

That flange is possibly used for turbos with welded wastegates, which mine is not although I guess it could be. I'd rather use a stock wastegate actuator if possible.

Confirmed that this is the correct 9b flange, the Weirtech link. Cyote, you are awesome!

well if its a galant vr4 turbo i have no clue but if its a 3000gt vr4 turbo then its a 9b and the bastards gonna spool if you even look at the petal lol but i guess thats good

what size injectors are you going with?? im thinkig of running the stock 3000gt vr4 360cc injectors but not sure if i want to get some bigger dsm ones or not. and the stock vr4 fuel pump lol . im planning on running the exact some setup as you. d15 with a 9b pushing 6psi (because 6psi is wastegate pressure). but the engine is about to die on me some im thinking a swap or something but ... idl yet lol + i just got a bigger turbo off a truck thats a little bigger then a 14b but im thinking of staying with a single 9b or twin 9b.... im thinking single 9b lol

what are your plans?? and specs and stuff??

pretty much im swapping all my leftover parts from my vr4 into my buddies crx lol
