ivee been trying to figure out the diffrence between these to for along time now even reading on here.

can someone please tell me the diffrence between the turbonetics t4 series t04b 60-1 and the 60-1 performance turbocharger. i dont want to have a miscommunication if im going to be buying a turbo. from what i read the 60-1 performance turbocharger is what you guys recommned, what kind of housing comes with it.

1990 turbo rx7

 

T04B 60-1 and the 60-1 are the same thing. The 60-1 has several names that people know it for. Like, the "60-1", "T04B 60-1", "T60-1", "T60", "T04S" etc. Why? I don't know. The 60-1 and 62-1 are Garrett wheels (some will say turbonetics exclusive, but their WRONG. I can get this wheel direct from Garrett and it has the same part number) and are there own breed of wheels although their listed in the T04B compressor series. They differ from T04B compressors because not only are they larger, but they run a 7 paired inducer blade set (T04B have a 8 paired inducer blade set up) and have a more effecient and modern blade design parralleling the T04E series. But unlike the T04E series which have 6 paired inducer blades. Also like the T04E the 60-1 AND 62-1 have back sweept blades. So their there own series essentually. When you order a turbo, just ask for the "60-1" (part number 20177) wheel. Your turbo supplier should know what this is. You can be more specific and spec it out at 2.324" inducer and 3.000" exducer. That way theres no mistaking what wheel you want. For max power and flow go with the T04S compressor housing in a .7 A/R. If you have space contraints you can go with the HiFi compressor cover in a .6 A/R. Its phsically smaller. You MUST spec a 60-1 HiFi compressor wheel (part number 20230) if you want the smaller HiFi compressor housing. The HiFi flows less then the T04S housing. It will have a slightly more linear boost response though.

alright let me run this by you before i start ordering a turbo. btw i have all the supporting mods already
T04B 60-1 P TRIM
OIL AND WATER COOLED
1.00 DIVIDED TANG EX HOUSING(i got divided manifold) with vband clamp
.70 comp side
360 thrust
dynamic seal

whats the diffrence with the big shaft?
am i missing anything else at all? im making sure this time because i have a ts04 i dont really want to use because i dont want to boost more then 20psi and my goal is only 400-420rwhp

Thanks

 

Specs look good. The T04S is more appropiet for your goals then would be the TS04.

The big shaft option is just that, a bigger shaft. It uses a bigger turbine shaft and appropriet bearings etc. Your TS04 should be a big shaft (the "big shaft option" is standard on the "T Series" turbos of which a TS04 is ). For the T04S and your power goals a big shaft option isn't needed. You wont be running extreme loads on the turbo, besides if you run extreme boost (over 17 psi) on the T04S you'd be out of the effiency range anyway. So its a option you won't be needing and it is a EXPENSIVE option. You could always go for the option if you wish, as it makes a overall more robust turbo. I don't know if you thought of this or not, but you can always just put a 60-1 wheel in your TS04 turbo and have the housing machined. In the end though, it may cost nearly as much as buying a new T04S, but still be a little cheaper depending on the options the TS04 has.

thanks for the help Mike, I'll see what i can do from here.

OK i did some more research and the only thing i need to know now is if i get the t04b standard does it come with the .70 comp housing or is it .60?

Thanks

 

If the standard is a 4" inlet and 2.5" disscharge its the .7 A/R. The smaller HiFi and standard T04B is 2.75" (sometimes 3") inlet and 2" disscharge. Get the 4" inlet. You need to TALK with your turbo supplier instead of trying to figure out things by reading online catalogs. Just call them and give the the specifics You already listed and what I gave you. Remeber, T04S compressor housing, 4" inlet, 2.5" disscharge in a .7 A/R.

perfect, thanks alot...

 

What is the inducer and exducer on a 62-1? A 62-1 should make more power efficiently, correct?

 

A 62-1 should be paired with the T04S compressor housing as well (4" inlet, 2.5" disscharge .7 A/R). The 62-1 does flow more air, but like anything, theres a compromise, a bit more time for spool up.
