I have a 2.0 Duratec, stock internals with no intention to upgrade internals.
I'm looking to upgrade the IHI turbo I have to a larger T3 from a Thunderbird/SVO.
They come in 2 sizes: .48 turbine and .63 turbine, both with a .60 comprsesor.
Looking at a compressor map either of these will work perfectly for my moderate 10-12psi and not run out of breath early like the IHI.

I'm leaning towards the .48 for a the faster spool vs the .63, but I'd like to hear what the folks here have to say.
I would think either would push air all the way to 7k rpm.

I'm pleased with the power the IHI made (204whp/224tq), but after 5k rpm it drops off very quickly because it's way out of it's efficiency range.
I want to see that power all the way to 7k rpm.

Here is a .60 compressor map.

Sure go ahead and post up your dyno if you don't mind.

Thanks! What is your low boost setting, and what size is your compressor?

In all the years I have been doing turbos for years I allways though a t3 s60 was just that and it didnt matter who or how it was built a t3 s60 was just that , about 10 years ago I got playing on the dyno just changing turbos from one co to another and all had the same trims and build specs yet I was seeing from best to worst turbos spooling 800 rpm quicker making in the range of 45 pound foot more tq down low some would reach 370hp some would fall off at 340

There are Co out there BIG NAME ONES that do nothing to move forward keep the same crap throw ball bearing at it , give it a stupid name and wana be turbo experts suck them up , I look around , test things and so far Comp turbo is a new and hungry Co and I have been very pleased with there work to date , I would see if Justin at Comp has anything you like then give me a call and I am a dealer for them now , I use there stuff because it works and it has shown that on here

So Tom, would you suggest the .48 or .63?
I appreciate your suggestion for the Comp turbo, and will look into them if I go that route.
Right now I'm just interested in the best choice between these two turbos.

i would go .63 im running that on my GTK-450 which is a 60trim t3/t4. you will get a fast spool up either way because the svo turbos are small

That's good to know.
I figured if the Tbird guys with the pushrod 2.3 prefer the .63 then I could run it without much problem.
Surely the Duratec head outflows the older 2.3 pushrod.

the .63 looks like it spools at 4500?

Personally I want a turbo that spools close to 2700. So if I were choosing I would go with the .48 It will spool sooner and still be in the power range I am wishing for.


But if your shooting for big numbers the .63 is the way to go.


In the end its your car, your call.

YAY!! A subject I know a thing or two about! lol The Tbird 2.3's are SOHC, no push rods. Here are some flow numbers of the stock 2.3 Turbo Coupe head:
-Lift"--Turbo D--
.050"--27.8
.100"--54.5
.150"--75.4
.200"--100.6
.250"--120.7
.300"--132.3
.350"--140.1
.400"--144.0
.450"--149.2
.500"--154.4
.550"--159.5
.600"--160.8

The duratec head in stock form flow only slightly better. I can't find the numbers in my files right now(LONG DAY!). On my turbo coupe, the .63 was at full boost by 3100rpm and pulled hard to 6k. The .48 was at full boost at 2700 but ran out of breath at ~5300rpm. I would say with a good tune you would love the .63! Boost should be full on by 3200 if not sooner(depending on mods) and would allow you to pull to 6500-7k. Hope this helps.[cheers]

Excellent info DSGcoupe, that was excactly what I was looking for!
The .63 is the way I'll be going.
It won't spool as fast on the Focus because of the weight difference between cars, but I figure full boost should be around 3600 rpm which is fine with me, especially if it breathes up to 7k rpm.
I stand corrected on the pushrod comment.

I've been told the T3's are pretty reliable and last a long time. What is your exprience?
I'll keep an eye on turbofords.net and ebay, but what are some other places I could look?

focusguy87, Turbo Turtle is running a more agressive turbo that I will be.
The one from a Tbird will spool a good bit earlier than his, but won't flow nearly as well as his.

That has been my experience with them as well. If you find one that is in good shape and used, I do recommend rebuilding it to be safe. You can usually get the rebuild kit for ~$125. These aren't necessarily as nice as some of your higher end turbo's but there rugged dependability makes up for it in my eyes with what you(and myself) are aiming to do.

I would definetly keep an eye out on Turboford(my home away from home. lol) and ebay you may also watch any of the following sites:

and don't forget about watching craigslist(the indy area always has them popping up)

Keep us updated!!

I don't know what happened to the last post but here is what I posted:

Aha there it is.
I appreciate the help, and if you happen to come across a .63 T3 feel free to PM me.
I'm also a member on the NATO board with the same screen name.
