I just received a 2554 in a trade and am trying to decide if i'm gonna end up running it or selling it.

If you run one, please let me know what you think.

My goals will eventually be for power but not for another 6 months.

What turbo did you have before? How much power are you looking forward to in the future? I am running a 2554 on my 1.8 and make 200hp at 9psi.

Well, I'm not worried about power goals now. Im gonna eventually buy a 2871 before I move but, thats gonna be like a half-year.

The turbo I had before was an sr20 t25g(I know, I know, LITERALLY the same turbo) but I sold it to my bud for his tdi caddy project. I never got a chance to run the 25g.

Threw some events and a parts trade I ended up with this turbo.

I just wanna know what some owners think of it and whether or not I should sell it or just run it for now.

I am making somewhere around 230whp with 15psi. It makes an excellent track turbo since there is absolutely no delay. Roll into the power, and the boost gauge sweeps right up with your foot.

It really depends on your power goals. If you're a highway/drag guy, sell it. If it's an autocross car, or a track car, definitely keep it.

I am tuning a forged 1.92 liter BP with a Bell manifold/DP and a 2560R later tonight. It'll be interesting to see what the spool numbers look like with that combo.

I am actually running a sr20 t25.

Its exactly as Savington describes it. The spool is instant, as soon as I mash the pedal im at 5 psi. But it runs out of steam when you get into triple digit speeds.

Running a T25G.

Plenty for me driving on the street, 14 psi by 3k rpm. Its great for flying around the city, not really good for top end.

iTrader: (24)

Allright, I guess i'll keep it for now. sounds like a fun turbo for city driving.

I appreciate the info guys. i'm just lookin for to make around 12-14 psi for now.

With my motor it should spool super ****** fast.

update?

my gt2860rs is hitting 10psi at 3600 pre-tune, for reference.

Savington

iTrader: (31)

Just finished. Maxed the damn 460cc injectors at like 11psi. The car pulls HARD, mabye 240whp+ at 11psi. I told him to get a Walbro 190lph and 750s and we can tune for a lot of boost.

We took a ride in his car and my car back to back, and there's a huge response difference. My car feels like a supercharger compared to his. His turbo is also MUCH larger in physical size. 2

So watcha think man, just sell the 25R and go for a 2560?

Or should I just hold out and get a 28RS or 2871

Savington

iTrader: (31)

It depends on what you want. My turbo spools like a lightswitch. It seriously feels like a supercharger. The 2560R takes a moment to come online, but once it's on the pull is smooth and hard and it pulls straight into the rev limiter.

When I move to Orlando I am going to want great top-end as I wont be autocrossing any more.

Oh well.....I guess i'll quit bitchin and just run this turbo until I buy a bigger one.

Thanks for all the input guys!

I may consider a gt2560r if dyno time doesn't move some hp up sooner. My motor is probably moving a bit more air than yours though. I'm sure my dyno will get posted up by next weekend.

Savington

iTrader: (31)

Hustler, you won't regret downsizing the turbo. Thesnowboarder's 2560 (the car I just tuned) pulls hard straight into the limiter.

viperormiata

iTrader: (24)

It really sounds like a 2560 is the choice turbo for our motors even with headwork.

I think i'll keep a look out for one or either a pulsar gtir turbo.

Please don't waste a built motor on the 2560r. I will say on my stock motor I love the 2560r compared to the gt2860rs. Much broader power. But it's maxed at ~300hp (which also requires more stuff than you have, intake manifold, etc.) Since you're motor is built shouldn't you be thinking 350hp at least? If I could turn the boost up/get a bigger turbo and had the engine to make it happen I would. You will get tired of sub-300hp.

FWIW I got mine up to a GPS indicated 132 and it was still pulling.

Savington

iTrader: (31)

350whp is damn near useless on track. I would MUCH rather have 280-300whp out of a 2560 than 350whp out of a 2860RS.

hustler

iTrader: (6)

corky recommended the DP for EGT considerations. We'll see what happens on the dyno. The extra displacement may help spin it up.

As for 350whp, I don't know that I'd be able to keep it cool or keep a transmission in it.
