Can someone tell me how much hp this turbo would be good for on a streetported 13b? And at what kind of boost levels? I'm shooting for around 330-34f0 rwhp at approx 12 psi


t04b HI-FI turbocharger. Equivalent of the Turbonetics Super S trim. The turbo comes with a .60A/R hi flow version for the compressor wheel and a 1.15 turbine wheel for very little back pressure. Can handle upwards of 30psi perfect for big engine twin turbos or drag racing small displacement engines. Turbine is P-Trim for quick spool up and response. Tang divided turbine housing for universal applications and divided for better airflow.

 

330-350 rwhpn@12psi sounds about right. 375-415 rwhp @15-18 psi. That turbo is an excellent choice, if of couse its a t04b 60-1 compressor wheel, you might want to switch the compressor housing from a HiFi to a standard .7 a/r T04B housing. The HiFi has slightly less flow with its 2.75" inlet and 2" outlet, the standard housing I believe is 3-4" inlet and 2.25-2.5" outlet.

Thanks for the reply Mike. Could you explain changing the HiFi compressor housing to a .7a/r T04B housing?

 

What he is saying, is to get the standard T04B housing with the larger inlet/outlet, rather than the HiFi.

So, you would get the T04B with the 60-1 compressor, rather than the T04 60-1 with the HiFi housing.

If you already have this turbo though, remember BDC is making 425whp at 15psi with the HiFi version.

 

cool thanks evil. I need another opinion and some info on another turbo if anyone wants to chime in.

Garrett Turbocharger. The P/N is 409770-5019 and the model number is TO4B25. The compressor A/R is .60 and the turbine A/R is 1.15 . The compressor has a 2.13 inducer and a 2.75 backwall and the turbine wheel has a P trim.

What is this one capable of? i think the .60 ar is holding back hp potential.

I have a couple of options and i'm trying to find the best deal

 

BDC is making 425RWHP with a full 60-1 hifi, not a to4b 60-1

oh and you probably want .7 on the cold side

 

that turbo with a .70 comp cover is pretty similer to the turbo i used to push my 1st gen into the 10's, good for 20psi and not much more, made 410rwhp on our dynos which is about 490on yours, if you want more go for a T66 with a 1.32 hot side with the P trim as well.

Dale,

So your saying change the .60 A/R comp to a .70 A/R comp? Thats it? I'm really only looking for about 350whp at around 12-13 psi on a ported motor. BTW this is in a first gen. I'm sick of the stock turbo.

 

What's the difference between the 60-1 and the T04B 60-1??

 

and who is BDC anyways?

 

Brain D. Cain. 425whp, daily driven, emissions legal FC

 

A friend of mine bought one of these to put on his FD. When he sent it off to be checked over, he told the guy what it was going to be used on, and was told that it wont take the heat that an FD produces for very long.

Better looking at the T04E or S.

Yes change to a .70 comp cover, much better than the .60, i personally would be sticking to a garrett 60-1 comp wheel , with a 1.15 p trim hot side, this will make around 360rwhp on 11-12psi on your dynos.
perfect street turbo.

Dale I'm sorry but I'm a little confused. What part of :...

"Garrett Turbocharger. The P/N is 409770-5019 and the model number is TO4B25. The compressor A/R is .60 and the turbine A/R is 1.15 . The compressor has a 2.13 inducer and a 2.75 backwall and the turbine wheel has a P trim. "

....would the 60-1 comp wheel be? I hope i'm not confusing you now. lol I'll put it another way. Does this turbo have a 60-1 wheel or if it doesn't what part of the description dictates the comp wheel?

I'm not finding any wheels that match that inducer diameter in the t04b standard Garrett line up of wheels. The closest I could find is the T04b "V" trim. Its a small compressor wheel, not really worth it for a rotary, I wouldnt spend money on it, UNLESS the turbo is so cheap, that once buying it and getting the compressor side upgraded to a t04b 60-1 and housing is still cheaper then buying the proper spec turbo first off. FYI t04b 60-1 has a 2.324" inducer and 3.000" exducer.

~Mike........

 

thanks

 

You guys are missing the point. The turbo has 2.13 inducer 2.75 major, this is not a high flowing wheel! His housing is the 2.75" inlet w/ .6 a/r. Basically he needs to change his compressor wheel AND housing.

Edit: I now see racerxtreme7 caught on. Good job

 

just posting to say i love you avitar. CAMEL TOES... CAMEL TOES!!!!

 

hehe ya but its getting old. got to change it

 

Sorry about this second post. What's up w/ the server? Please delete this as I can't.

 

Ok, I add another question. It seems the turbine A/R is all over the board when it comes to recommendations. Some people say .84, some .96 and some go all out and recommend the 1.15. Wouldn't the .84 be MORE streetable and still produce 350+ rwhp. Oh, I'm referring to the T04 60-1 .70A/R compressor.

I like my hybrid's low/midrange hp and hate to give it all up.

yea im looking for some sort of turbo that would make good low/mid power 3k and up and still have some steam to pull 350-400hp
