Thread: SR20 Turbo 02 Housing R&D

Very nice, a tip, make the 3-bolt flange out of the thickest stuff you can order...one I got from Aussie land was too thin and warped quickly...

Cool, I figured you knew what was up. Another option (the best IMO) is to use a '93 NX line to keep more clearance. There are lots of great pics and an explanation of how this works in this thread: http://www.sr20-forum.com/forced-induction-turbo/19989-ac-lines-turbo.html

I am so glad someone is finally following through on this, I tried to come up with a prototype years ago, but gave up because everyone wanted a/c and it was just too tight.

The 3 bolt on these is as thick as the OEM flange. We use this thickness on all our down pipes and they are good to go!



Thanks for the link!

Bluebird/Avenir divorced waste gate w/ screamer pipe is complete!

Stainless steel version, fully TIG welded.






AC and Alternator friendly!


Turbine flow fully divided from waste gate flow

Where and when can I pay

• Avenir w/ Stock T25
• Divorced Screamer
• Stainless
  

Let us know when there ready to ship.

Avenir stock t25, internal W/G
screamer,

where can i send $ for the prototype

If you expand the non-wastegate pipe to fit sungly inside of the respective turbo, then that would seal well too, but you'd need a t25 and t28 to trim and fit the pipe, that would be best exhaust flow.

Man that thing is nice... will you be making one that recirculates the screamer pipe back in?

These are awesome make a gtir one and I will buy one, and a 3 inch down pipe once you make one. Oh and will the final version have a bung for the 02 sesnor?

I am going to make a couple of mods to the part pictured....add an 02 bung along with a sheet metal brace that ties the screamer pipe to the exhaust pipe. This first one is yours , I'll let you know when it's done, most likely tomorrow.



I'm out of flanges. More scheduled for delivery by the end of next week. Your next on the list. I most likely will make these one at a time unless their is a large enough demand for them. If you prefer, I can send you an estimate which will convert into an invoice once the part is done.



That's something I might try in the future since I am in the market for a hydraulic swager/expander/tooling. Also looking for a GTIR mani and turbo for mockup. If any has one, let me know!



Yes, recirculated bluebird/avenir setup is next. Material will be here tomorrow, but I won't have flanges till the end of next week. I'll post it up as soon as it's done!



GTIR is in the works...I'm searching for a GTIR mani/jpipe/turbo now. These will all include a 18X1.5mm 02 bung. If anyone uses the "skinny" 02 sensor, you can also run it with an adapter.
