Does anybody happen to know where i can find the specs and info of the M2 twins and the difference between that and stock?

I looked everywhere on this forum and fd3s.net, couldn't find much about any M2 product other than their IC or intake. Only thing that pointed me in any direction was a manufacturer stamp on the turbos with GCG on it (www.gcg.com.au). Unfortunately it's a discontinued product, wasn't able to get much info from their site.

Thanks!

 

I believe they were basically GT25R's worked into the stock housings. I thought i'd read that an Aussie tuner did them, and M2 just rebadged.

 

Peter is right. I drove Jason Manley's FD with that setup when it was at our shop and it spooled pretty damn quick. They were twin t25s.

The BNRs are twin t28s, so more power potential and run sequentially they'll spool just as fast as the old M2s. Anyone interested in ordering a set of BNRs, shoot me a PM for more info

 

Rich, IIRC, the M2's were full ball bearing, in other words GT25R's... are the BNR's ball bearing (I thought not)?

 

Not sure if the below info suggests full ball bearing but I don't think so.

The thrust bearings are upgraded to 360 degrees for proper lubrication of the rotating assemblies up to 180K rpm! This means you can run a tremendous amount of boost without killing thrust bearings. The stock thrust bearings are 270 degree bearings which aren't reliable to run over 15 psi of boost. 360 bearings are standard on BNR Stage 3's.

 

I have a set of these in my garage waiting to go on. They have an 'XTR & Performance' decal, which is an Australian company (now called GCG Turbos: http://www.gcg.com.au/) so they were basically just rebadged by M2.

I hope to bolt them on later this year.

 

Peter, you're correct again . The m2s were bb, the BNR3s are not. Bryan tried to machine me a prototype set of BB Stage 3s but he just couldnt get it to work, I think he had fitment issues and kept ruining housings trying to machine them out enough. That's why I ended up going 500R.

 

cool, thanks for the quick replies! seems like info on m2 stuff is far and few between

 

That's because they've been out of business for quite some time now.

 

Also, it seems that very few people installed these turbos. Is there a single board member currently running them? There are a few old threads for 2003 and 2004 but it does not seem that anybody really got these running in a properly sorted FD.

 

Would it not be possible to call them and find out if you can send them your stock turbos to perform the "M2" upgrade?

Not a bad price for $200.

 

Probably. Here is their number:

Int +61 (0) 2 9708 2122

 

Personally, I like the gt28s in the bnr's. I can't wait to get my car running with them.

 

360whp at what boost level? Stock ports?
