Let me start out with this and say I just want alittle more power than stock and don't plan on tearing into the motor.

I bought a GT25R Garrett dual ball bearing turbo at a steal.

I went with this turbo for the size and quick spooling, I just plan to use it as a daily driver and do alot of city driving.

Of course I have the normal, BOV,intercooler and injecters and I am going to tune it.

I added this to a log manifold (Same thing as a Pfab type)

Has anyone run a GT25R or heard of someone running one?

Just looking for thoughts

The GT2560R is the perfect turbo for 99% of stock-bottom-end Ds.
The GT2554R is a fast spooling little mofo, but its too small for the D imo, but would still meet a lot of peoples goals.

The reason everybody runs T3 flanged turbos is because all the cheap and available manifolds are T3. At ~200 hp, they would be better off T25 flanged.

I was contemplating running something like this on a B, to try and make 300whp. I need to brush up on my compressor map reading...

My friend had a gt25r in a 92 eg hatch with a d16z6 few years back. He was running around 10psi with water injection on stock head and block. Mid to low 13s in the quarter and reliable too. Good luck

Order the T25 to T3 Adapter (Low Profile)... WOW! that wasn't cheap..

Then had to order the bango fittings for the water lines and oil lines... Found a nice kit on ebay for a company that says it made in the USA...

I just hope with a Log Manifold and the low profile adapter the turbo clears the AC lines

I really like the t25 for a DD, power instantly, but can make 35+mpg.

Had a T2554: made 230hp 220tq on 15psi
Spooled by 2.2k
(Blew oil seals after 30k+ miles)
Now a T2560: should be close to 260hp (havnt been to the dyno)
Spools by 2.3k ( not much slower at all)
Pulls better on the top end

This was on my d16y8 vitara build, 9.6:1 comp, 3" exhaust, z6 cam(stock), t3 mani w/ 0.75" adapter plate(found on ebay yrs ago~$65)

The t2554 is what I would chose for a stock block, just have a good flowing WG and large exhaust.

How do you plan to bolt that to a pfab-style log? That adapter needs the T3 bolts to come from above/thru the manifold's flange, while a pfab type manifold needs the bolts to thread up thru the turbine housing. There is another style that is a bit taller, but allows you to put bolts in thru the adater's flange so it can bolt to a log manifold that uses close-ended (blind) bolt holes.

Drill the Manifold or the adpater plate?

Looking at the plate I go coming could I drill all the way through it so I could add bolts?

You're going to need a tubular manifold to use that adapter. The kind that uses bolts, bot studs.
The problem is that they will all be expensive or super shitty.
You should have just gotten a cast t25 manifold. China makes t25 drag manifolds now.

I have two options right now...

One is I have a PFab Log manifold (New) with a td03 flange and I have a China Cast Manifold with TD03 flange...

I ordered a Mild steel td25 flange that I can weld on to the Cast or log manifold...

Kind of don't want to weld the log since they $300... I was going to weld it to the cast and sell the log..

I know welding to cast can be a problem but I have decent skills as a welder...

Was told to maybe heat the cast up pretty good then weld withthe mig at the highest setting...
