.42/.49 a/r CX racing T25 - was that a mistake?
Guys,
Hoping I didn't make a mistake. . . Wanted a turbo that would provide maximum response (autox), and be roughly 200whp capable on 91oct. Looked at sr20 T25's and GT25r, but in a moment of haste bought this:
http://www.cxracing.com/mm5/merchant...ry_Code=T25T28
Link says 250-300 hp, which I thought would be perfect for my whp goals.. However, after reading the max achieved on an sr20 t25 and a gt25r, I'm a bit skeptical this little guy can do it. What do you guys think?
For context - Car is a '96 w/ a stock motor. MSPNP (gen1), and a standard cast BEGI kit w/ intercooler. E85 is an option, but the idea was 200 whp on pump, and 220 on E85..

subscribed...I just bought the same POS and would like to see 200 ponies as wel on 1.6 NB...but nearing a point which I am close to take it back and get a propper GT2560(full boost at 3300rpm) of a SR 20 motor...I asked the same qeustion and 18psi was kind enough to tell me that I would see 200 maybe a little over at 14 psi but that would be stretching the turbo's limits and you wouldn't see more after that...the spool(reckon should be close to full boost @ little over 2000rpm,just my geuss though) in this POS should be wicked though,reckon for auto X it should be kick ***....just my 2c.

Are all CX racing DP flanges not standard Garrett flanges? I know some chinachargers were, and I had issues with this one:

but it's a "new" design, and I figured some of the others would fit.
I think a lot of people don't have issues with Godspeed turbos, search for them on ebay. Or buy my greddy turbo, it's a genuine Garrett and exactly what you're looking for. Abe quoted me $710 for a gorgeous manifold/3" downpipe, but sounds like you already have something.

Even godspeed turbos don't have the "regular" t25 flange.
Look at this pic I sent to Godspeed:
It appears that many, if not most, chinachargers have their own weird version of a 5 bolt downpipe flange, which is just a few mm off (at best) from the regular ol one

Post #68 shows the difference between the CX racing flange and a Garrett flange.

The SR20 is very very appealing. Standard 5 bolt flange...my FM cast turbine outlet bolts right up to it. I could include that outlet with sale of my turbo as a package.

hi bro,
I recently purchased two used SR20 T25s with all the factory accoutrements for $50. Deals like that are rare, but if you look around, you can ball out on a budget.
I also bought this to solve my downpipe woes:
http://www.ebay.com/itm/180753514045
Hopefully my DP will be less than $100 to have mandrel bent.
:-)
Again, no reason to fret. You should be able to return that turbo to CX Racing if you change your mind. I know what it feels like to impulse buy

fwiw, it's the same exact compressor wheel I have in my china T3.
but my turbine is much larger, and has a .48 A/R T3 turbine housing...so it would be like a .64 a/r t25 sized.
I hit 240hp/240tq.
I'd expect this turbo to spool fast as crap and achieve 200rwhp, but have no top end wahtsoever.

Frankly, I'm starting to think it may be best to avoid CX Racing turbos.
I've been playing around with one, and testing a thread's fit by hand, we're not even talking finger tight, we're talking I just threaded the fitting in by fingers....it stripped the threads in the oil feed.
Poor quality is poor quality. Although I love their idea for a turbine housing.

Not sure about those, but my godspeed oil feed and return has very strong threads that never had issues.
Also as Brain said: id probably rock this on a 1.6 with auto-x in mind, definitely not a 1.8 though.
OP is returning it though so who cares lol.
I thought the only chinachargers somewhat decent these days are godspeed and speedyracer or something like that.

My first turbo was a .48/.49 T25, an OEM Garrett part from some Pontiac. Standard T25 flanges. Made 13psi at 3000rpm, 200whp and 205wtq. Hilariously good boost response. If I were looking for 200whp and no more, that's definitely what I would try to find again.

Doesn't sound too far off from my T3 piece together... .42a/r with 50trim, T3 housing with .48? turbine
Was good for 231 on my 1.6 - added a 60trim and I'm at 274, but much slower spool, fwiw.
