Finally time to go big turbo. Either Eliminator or T Series Garett Turbo.. Whatcha gu
 
I'm trying to go as cheap as possible with this build guys :(
I know you guys are probably ganna be pissy at me for wanting to be cheap, but I want a little more fun out of my car without having to pay great costs ! I has no money.

Anyway, ATP Turbo sells just the eliminator, and from what I understand, thats all bolt on. After that all you need is a tune correct ? I have a unitronic tune now, so I'm assuming it would be cheaper. I already have a custom downpipe fitted and a stage 1+ unitronic tune.

Then theres the T series Garett turbos.. From what I understand I would also need a manifold correct ? These turbos are actually pretty cheap so the cost of the manifold added on to the cost of the turbo isnt so bad. How do the tunes for these work ? Unitronic has them ? What else do I have to buy to complete the project if I just buy the manifold and the turbo ? Just hoses ?

I'm still kind of noobish at all this, but would certainly appreciate your guys' advice !!

Labor would all be done by me.

Thanks !

P.S. I tried searching for something like this, but nothing really included the T series turbos.

The elims suck. They spool slower than a much larger turbo due to the poor housings and stock manifold while providing less power also. You need a real T3 manifold. I have a atp clone manifold im not using, its yours for $50.

as for T3T4 info, you have to know where to look

These turbos are all journal/thrust bearing turbos unless the chra (center cartrage) is changed to a DBB unit. They are often just oil cooled unless again, upgraded. You can also get the T series turbo in two versions, 270 or 360 thrust bearings. The 360's oil far better and since the T series turbos use more oil, it is a good idea to get the $50 upgrade. If it doesnt say 360, it is a 270 thrust bearing. Pagparts.com is the only place off the top of my head that i know of that sells both. As stated before, journal bearings spool slower which isnt always a negative. A t3t4 turbo can make more power on the stock rods than a faster spooling GT turbo. Not to mention that since they use older tech, they are about 1/2 the cost of a GT turbo. You can however decrease lag on a T series with a smaller housing (using a .48 instead of a .63). The T3T4 stands for a T3 turbine wheel matched to a T4 compressor wheel. These turbos are most often matched to a balanced stg3 wheel and a stg5 as an option. Turbonetics often match theres up with a stg2 for slightly faster spool with less top end. The lower the number, the smaller the wheel for faster spooling, the larger the number, the bigger the wheel for more top end and flow. In most cases, a stg3 wheel would be best. Another thing to be noted is that different manufactors recommend to use a restrictor disigned to limit some oil pressure while others do not. Please consult your turbo supplier to get the correct specs otherwise your turbo's life will be shortened greatly


T3s60 - 270-310whp - 3400rpms
T3T4 50trim .48 - 300-375whp - ~3800rpms
T3T4 50trim .63 - 300-400whp - ~4200rpms
T3T4 57trim - not a very efficient turbo, surges above 20psi. Avoid use.
T3T4 60trim - .63 - 320-425whp - ~4400rpms
T3/GT40 - .63 - 375-600whp ~4600rpms (GT35/40 82mm wheel with stg 3 turbine wheel)
SC61 - .63 - 375-600whp ~4800rpms (GT35/40 82mm wheel with ptrim turbine wheel)
TURBINE WHEELS
stage 1 ( 1.916 / 2.320 )
stage 2 ( 2.120 / 2.555 )
stage 3 ( 2.227 / 2.555 )
stage 4 ( ????? / ????? )
stage 5 ( 2.437 / 2.795 )

Same applies as above, to max out these turbo, you will need to rods. Also when you choose, you can upgrade the chra to a DBB unit and have faster spool and higher power potential. Take into account, if you were using a .48 housing, you need to swap to a .63 housing with it also.

As for tunes, you want a eurodyne/tapp tune. They are cheaper and better than a Uni tune. Plenty of parts can be found used to save you a ton, just best to buy new turbos.

Yeah I actually read over your sticky multiple times and thats how I even knew about the T-series turbos. From you.

Anyway, are there any write-ups on the internet where people have actually made a setup like this ? I only ask because I don't really know what parts to buy. And a little buying guide would really help me out a lot.

People use 50trims all the time. Its probably the 2nd most popular turbo on a 1.8t.

btw, if you have no money, going with a larger turbo isnt the smartest thing to do.

SupraSkylineSTI 04-01-2010 10:54 PM

Which one should I go with if I generally don't want to change my rods ?

cincyTT 04-02-2010 10:46 AM

50trim with a .48 would provide decent spool and make 300hp at about 19psi
