Title: T3 Replacement Turbo ????
Post by: stewardc on September 20, 2008, 06:10:38 pm

Does anyone have any ideas on a good NEW turbo to replace my tiring Garrett T-3 ?  I need a direct boltup that will give me power a little lower in the rpm range, but still give me 20-25 psi reliably.

I'm pretty sure Giles can get you a new T3 or K24

Wow, I thought they were obsolete. I'll try him.

a VNT if you have money to burn?
I don't know if a VNT is just an easy swap someone will chime in but if you want a big upgrade a VNT would do it for your.

But they're expensive

Sorry, but for my money a VNT is unnecessarily complex. It also has an electronically controlled linkage with no way to control nor activate it on my engine. A simple turbo is what I crave.

Why not just order a high performance rebuild kit and do it up?  Or send it off for full rebuild and balance,  it's like 400 bucks.

What a great site. It will be done on Maine, but I wonder if there's anyone that does this in Canada????

Steward, call this guy, he is awesome:

http://www.timsturbos.com/

1-866-3Turbos

Talk to him about your application.  I think it is a one man operation, and Tim is a real cool dude and may have some good advice.  He rebuilt my T3 very affordably if you wish to go that route, he also balances and does all the other stuff, it was like brand new when it came back.

I guess I'm really looking for a "better" turbo. A ball bearing unit that spins up earlier.

Looks like you have a couple options then.  Go to something like the ko3 / k14 for faster spool. You know the deal there, more down low, less up top.  Go the VNT route with it assorted control systems. Fast response and power through the whole range.  Newer ball bearing setup, faster response but costly.   Kind of the big catch-22.  Perhaps the addition of a water / meth system would help?  Different direction, but it may achieve the results you are looking for.  Sell the IC setup and go with water / meth into the manifold.  Prices might offset each other.  Faster spool for sure, your whole loop will be like 6".  Just a thought.

I had a K14, don't want the troubles of a VNT. I just need the ball bearing unit, but does anyone make a direct-bolt-on for these manifolds?

I don't know of any other engines that used the trapezoidal flange except I think I saw one on a nissan once.  Short of finding one to bolt on, you could choose the one you want and make it fit.  Adapter plates aren't hard to make.  I've made quite a few with 3/8" steel, a drill press, hole saw and a power jigsaw with metal cutting blades.  Just made one yesterday for a VNT 17.

Got any pics of the plate?

If you really want ball bearing you can get a standard T3-T4 flanged manifold off E bay then get what ever you want.

Are there flanged manifolds for an AAZ on eBay ????
A manifold must be matched to the head it's to be used on.

WOW!!
REALLY!?!???

You cant just bolt any old manifold to the head??


Good hell man give me some credit.   :lol:

AAZ is the same as the 1.6 from what I remember.

There are manifolds available.

I have the same manifold here (waiting to be used currently.)


The down side, it does not have a port for an external wastegate (I also have a tial 38mm waiting to be used...) I'm going to machine one in, since Cast iron is VERY tough to weld to and not have cracks develop.


Bigger wastegates control low boost better. I'm gonna be pushing 20psi through my merc t3/STI intercooler setup/

You could make a small say 1" spacer to pull outof between the turbo and manifold?

I fear it may cause some lag.


the casting is thick enough to clean a flat area off and machine in the hole pattern and port.


I have to wait to see how everythings going to sit before machining, I dont feel like doing it twice...

i'm gonna argu that point cast iron is very easy to weld! knowing the process is the key!
pre-heat and stick weld with nickel rod ! the reason for nickel rod is it still can be machined! if it don't need any machining then 7018HR4 will do fine!
i'm a Ironworker by trade welding is my game

To much time and effort  I can machine it in in very little time, and for free.
