Godspeed T25/28 vs Used Garrett Turbo from SR20
 

I know you shouldn't build a turbo setup around one peice. But I HAD a running turbo setup that used a fleabay T25/T28 that pretty much fucking exploded. My manifold and DP are good quality parts (BEGi Log Manifold and S downpipe). However, I need a new turbo. I can get a used Garrett for ~$250, or new Godspeed turbo for ~$275.

I don't want to hear people talking shit about the godspeed turbo, or what the fuck ever. If you've never owned one...STFU & GTFO.

Guess the real question is, How does the Godspeed stack up against the Garrett. I searched (don't think I haven't) and have only found where people say the Godspeed turbo is good for the price. But has anyone ever started out with a Godspeed turbo then switched to a Garrett or vice versa?

If so,
Spool characteristics/differences between the two?
WG operation, did it hold advertised psi?
Durability, Mileage of Godspeed turbo vs Used Garrett?

Also; I've heard of rebuilding Chinachargers with REAL Garrett parts and it makes them pretty fucking awesome..Any truth to this?

Thanks for your responses in advance,

Had a godspeed 3076. loved it. new owner is enjoying it now and its still running like a champ. I don't think there are many here that have t25 godspeeds. Most have the 28/30. The results are really inconsistent, so I doubt you'll get ONE overwhelming answer here. Some have made REALLY good power, and some not so much.

Bought the shit from BEGi to solve issue with cracked manifold; ran great for ~300 more miles then this happened;

Discovered that the turbo was POURING oil into my exhaust; so this happened;

Car never made boost again, I couldn't find a fitting for the turbo oil inlet. Car went back N/A and all turbo parts sit in a corner.

and the car sits like this now;

Does the 28/30 use the same DP bolt pattern and flange as the 25/28?

The car mainly gets used for AutoX and driving to work once or twice a month. Because of the AutoX side of life the car enjoys I need something that spools pretty fast to ~8-10psi. Does the 28/30 spool fast enough that I wont be left holding my dick on corner exits praying for boost?

How much power are you looking for? At 9psi from a sr20 2554 I made right under 200hp and 200ft/lbs of torque. It was almost a perfect an Autox setup. I would personally go with a genuine garrett if you are using the car for Autox.

But is a USED Garrett better than a NEW Godspeed turbo?

I'm just scared to buy used shit I guess.

I bought my sr20 2554 off a guy for $100 and put something like 20k on it, then sold it to another user on here. He has since sold it again and I think it is still in use. Just make sure the real garrett has no shaft play and you should be fine.

I thought the OE turbo was a 2560R?

Thanks, will do. They are the same price, so i guess I'll go with the real McCoy.

Yes, I would have to say it is better. I've driven a chinacharged car and it was not "Zomg! Uber slow spoool!" but the transition into boost was noticeably different. It was a T25 equivalent of my gt2554. I think it's more of a quality control issue than anything. Some are great, some are meh.

Don't be scared of used parts. Every part you put on your car instantly becomes a used item. I traded parts to get my used gt2554 and it's fine. Just know what you're looking for if you inspect it before you buy it.

EDIT: The SR20 T25 is also known as the T25G and it's a great turbo. I used to run one, before I ended up with the gt2554. They can be rebuilt for dirt fucking cheap (if ever needed)

I agree: if you're going to beat on the car constantly (autox) I'd definitely go with a good condition authentic garrett or something else that's brand name.
And there's nothing wrong with a used turbo as long as its in good shape.

the godspeeds use a weird 5 bolt turbine outlet that's ALMOST like a regular t25 5 bolt but just a bit off, so you have to make your own dp or have a godspeed specific flange welded to it. At least that was the case with my 3076.

It was perfect for my driving style and I loved it, but I'd say a 30 would be quite a bit laggy for auto-x use.


Get a brand name 2560 or equivelant. I think it would be the perfect turbo for your goals.

Journal vs BB will also effect spool.

BB = $$$$$$$, and I only have $$$

Found some T25Gs on Ebay, price range from 191 - 300, used. says they're in "good shape, with little or no shaft play and turbine spins freely" https://www.miataturbo.net/forum/images/smilies/gay.gif

On small turbos like the t25's the bb vs jb spool difference really isn't that drastic IMHO.

thats good to know, because i'm going with the JB to save meh greenbacks.

Vlad, what ecu/injectors/other mods are you running?
build page?

diypnp, 1000cc, bunch of other stuff
Not running anymore tho, car is sold :cry:
my build thread is in the builds section.

If you don't mind me asking why did you sell it?

Sometime in the near (hopefully) future Im going to start on another one just like it but with more cylinders under the hood. No replacement for displacement.;)
