the hot side look big and if it has a .89 AR it may be a T4

but if it has a .48 AR in the compresor im not sure then

It looks like a T3 flange..... most T25 turbos are internally wastegated ( this one isn't )

The compressor seems to be larger..... it depends on which picture you look at.... are the two housings roughly the same size or is the compressor larger??

It's either a large T3 or a small T3/T4 .... either way it's not that big... so it's probably usable on your Nubira engine.

+1. A good match for the Nubira.

Now go find a nice external wastegate and the rest of the turbo pieces and start boosting!

i am not a turbo expert but it looks like the t3/t4 turbo on the 2.0 nubira.

sweet, thanks

the intake size is the same size or Maybe a little bigger then the exhaust, but not Considarably.

next step i guess will be an intercooler any hints on who make a nice fitting cooler for the Nubi ?

Don't forget SRT-4 neons. Any of the fatory intercooled cars are going to have an excess of stock intercoolers around due to people upgrading.
Another place to look is ebay. SSautochrome makes absoultely sickennening turbo parts like wastegates and blow-off valves... never to be trusted ever.... Their turbos fall apart too. BUT.. they have pretty good intercoolers. I guess it's hard to mess up something with no moving parts. You may want to check them out.

Where have you heard this? Seams everyone I talked to that has a turbo car has gone through them without problems, including myself.

I'm sure they have gone fine through them... But get a few miles on the turbos and things will change. I have dealt with SSautochrome a few times. Any reputable turbo site will advise against the company but when you do custom set-ups, customers will bring you their parts a lot. The last time I dealt with them was with a D16 civic. The head flange on teh manifold was warped and I had to send it away fo rmachining. They sent cheap fittings. Two of them broke so I jsut went ahead and replaced all of them with quality earl's fittings. After I got the turbo on and all of the oil lines connected I quickly learned that the BOV flange was not welded to the charge pipes. The charge pipes also did not evern come close to fitting. I had to cut them in five places and reweld The downpipe hung the exhaust roughly6" below the oil pan... the completely wrong place. I had to cut and reweld that in two places. There was no O2 bung on the downpipe..... There were other notable things in the install that I wont mention.

Started it up... THe BOV isn't opening. I tested for vacuum at the valve and it was reading perfectly fine in all instances. Cupping my hand over the valve I could feel the vaccuum leaking past the diaphragm pull against my hand. Putting my hand over actually changed the idle... that's bad. I decided not to worry about the surge until he picked up the car. Took it for a test drive... would not get into boost. At idle I could feel the pulsing exhaust gasses coming from the dump tube off the wastegate. When I snapped the throttle it picked up... so the wastegate was dead too.

I sourced him a used tial wastegate and a 1st gen DSM bov and I put those on for him. After that the car ran great and pulled strong under 6psi with an upgraded fuel pump and a VAFC for about two weeks. After that he brought the car back and said it was smoking pretty bad. I rebuilt his turbo for him, the turbine seal had broken. I replaced the crappy aluminum bearings with brass turbonetics bearings and replaced the compressor and turbine seals with garrett parts. While in there I also noticed it had a cheap thrust collar and bearing so I replaced those with turbonetics parts I had laying around without charging.

The car has now been running fine for a few months. But in the end he bought a $600 kit and ended up spending almost $2000 to make it work reliably where-as he could have bought a Greddy kit used for more like $900 and instalation would have only been like $400 as it would have all fit and worked well the first time. Only the intercooler was any good. That was just my last experience with them.

I always make SSautochrome kit buyers sign waivers before I install their kits because they never fit so the normal $400 fee goes up pretty quickly when things start going wrong.

In the past I have had three other turbos from them fail, one other leaky wastegate, one wastegate with a torn diaphragm, two blow off valves leaked vaccuum and one blow off valve leaked boost and wouldn't even come apart so that I could find out why. They have never made an intercooler piping kit that fit. They have never given enough couplers. Only one of the downpipes ever lined up with the exhaust. The head flange being warped is hit or miss. After a few months the turbo header welds at the head always crack because they don't cut reliefs into their flanges to expand with heat.

I can dig up pictures of one of their compressor housing that actually split in two...

Just a bad company selling terrible product to people that are awe-struck by the low prices. That's why almost all of my off the shelf parts are HKS. I am currently using twin ssqv BOVS and a 40mm external wastegate from them and the quality is simply amazing. I never use anything but turbonetics or Garrett turbos (HKS rebadges garrett units)... currently using a P-trim T3/T04b garrett turbo on my sunbird and a Variable geometry GT22v on my diesel VW golf. I have never had a problem with anything from good manufacturers but is see the cruddy SSautochrome stuff every day as I build engines for a living and it never holds up. Nothing but the intercoolers... again, you can't mess up on a part that doesn't move or get really hot.
