I have recently come across a deal with a new GARRET dual ball bearing TA45 with my choice of turbine housings (1.05 ,1.15 , 1.22 or 1.32) , question is how would this turbo work compared to my T66 1.15a/r in terms of overall power and response ? , I plan to run 25+ psi with a monster street port , hurley race seals , water/ methanol injection etc, etc.

 

The only thing I have to say is, contrary to conventional wisdom, ALL ball bearing Turbos (not just Apex IHIs) are essentially non-rebuildable when meeting with catastrophic turbine or compressor damage. Although the Garret (unlike the IHI) may have part replacements available so you can purchase an entire center section (bearings, housing, turbine shaft etc) the cost of that unit is likely to be VERY high. Think long and hard about the use of ball bearing turbos. Yes they are very dependable and long living, unless and until the day when an apex seal goes bye-bye. Trust me, you don't want to be looking at another $1500-$2200 expenditure on top of the engine you will be replacing.

Good Luck

 

I know some of you can answer me........ ,RICE ,CRISPEED,ReTed , Greg ,Gmonsen and others . Please reply the deal is to go down this Friday!!!.

 

It's hard to say...
"TA45" is a family of Garrett turbos, and it's the same thing as telling us you have a "T04B" or a "T04E" turbo.&nbsp Can you get specs on what the compressor wheel size is?&nbsp Another member had a "T51", but after measuring compressor wheel size, it turned out to be a T66 compressor wheel.

In general, the TA45 sizes run in the T66 - T72 equvalent sizes, so you might not be picking up any gains with the exception of the BB center.

The exducer is actually smaller than the T66 , which is 3.48 as compared to 3.67 ".

 

Correction , the exducer on the TA45 is 3.04" and the T66 is 3.85" , I know the T66 would make more peak power overall but I am a bit cincerned with the overall power band ( responce) through the various RPM ranges, since the TA45 is BB I know it would respond faster but what would the overall performance be since the compressor wheel is soo much smaller , would it make just a good traffic light racer or would I have a good bit of both worlds (response and power)?

 

I dont beleive the TA series are BB at all. Only the GT series are. A few guys here in Oz are running them and i am 99% sure they are standard bushings...

I could be wrong though.

 

Ballistic Concepts has been teasing the SEMA goers for the past several years with a TA45 BB turbo cut-away.&nbsp Everytime I ask them about availablity, they say they have no clue.&nbsp Maybe it was finally released?

Yeah, the comp wheel measurements should be similar, but the wheel profile is a bit taller than the T04 stuff.&nbsp The TA45 is a bit more newer in technology, so the wheels are supposed to flow better.&nbsp You can get a rough estimate on power potential by comparing inducer and exducer/major sizes across with the T04 stuff, but the TA45 should flow 10% - 15% more on similarly sized comp wheels.

guys 4SFED is correct the TA-45 garretts do NOT have a ball bearing centre, I have a TA-45 garret and can assure you it isn't BB, also i think you will find there are many different shapes and sizes of the TA-45, and i have been told that the sizing is different example
TA-45 1.32 ex housing will be bigger than a T-04 1.32 ex housing

I guess Garrett mislabeled their display or you guys in Aussie have no clue what you're talking about.

I wouldnt rule out either option! hehehe

AJC13B had/has a hybrid TA45 i beleive and that is definately not BB.

Garrett could of released a BB versoin but i would of thought this would of been the GT42/45 series.

 

Mine is definitly a standard bearing turbo... If your going to run high boost I think you'll like it better than the T-66... buy it and try it.. at the least you'll have a spare turbo so when one ****'s you'll be ready..

 

I have a TA45 and it is not BB. As far as i know the TA series is NOT bb.
