Wondering if any of you had this turbo on their RX7, and your opinions of it.

 

tons of guys use them. a little small for my taste, but good blend of spoolup vs hp.

good for around 400whp @ 16psi on stock ports in an rx7.

 

Cool, I have decided to get rid of the stock Greddy turbo. The guy that is doing my car is getting me a 60-1. I have custom made low compression rotors, ported motor, walbro fuel pump and 720cc injectors for my secondaries - Thank you Scott from Mazport, the fit right in! I'm taking my car in on Monday.

 

how much for the low comp rotors? Just curious.

 

What compression ratio are they?

 

Not sure, I'll ask him on Monday. I drove the car NA and it was definitely less powerful than when I was NA w/high compression.

 

I'll ask him on Monday as well. We are focused on getting the turbo done and taking it to the dyno.

 

Are you planning on putting the 60-1 in the same location as the greddy turbo?

 

No, I don't think anything fits down there. I believe he is putting it up on top.

 

i'm putting a t70 right alongside the engine, but i had to build a new motor mount bracket.

 

yessir, i am

 

turbonetics sucks.

this is actually a semi-custom turbo. i had the shop stuff the t70 compressor into a smaller t04s housing. kinda like the 60-1 hifi's in the t04b housings.

not as efficient, but more space conservative.

 

guitarjunkie28, can u give us some details on your setup... or is it a secret for now?

 

I love the 60-1. It's a good turbo that is realistic for street use. BDC on the 7 forum has put down 425 rwhp with a street port at 15 psi of boost using the smaller version of that turbo the 60-1 HiFi. I don't think it's too small at all. In fact I think anything larger is a waste of time unless you have a dedicated race car but I also don't like having the powerband of a Supra. That's just me though.

 

i hit full boost at 3200 rpm with my t66 on a small streetport... nothing racecar about that.

 

secret for now, but i'll post up when i'm done with that one.

 

my rx7 hits full boost at about 2500 when i stomp on it. 13-14psi 60-1hifi. other rx7 people here where im at like to show off their big turbos but get spanked on the street. 60-1 is a good street turbo.

 

street racing is for kids

 

Update:

I saw the car today. They were just done with the down pipe and installing the wastegate. Here are the pics. The turbo brand is Precision and the wastegate is Tial. I am looking at early next week to get it tuned.

 

Just for the record, how fast a turbo reaches full boost has nothing to do with whether or not it is a good turbo for the job. When I say I like the 60-1 over larger turbos such as T-66's or higher, I say that from an efficiency standpoint at a certain boost level. At 15 psi, that turbo will put out more power than a T-66 or larger turbo can on a rotary. Even the smaller 60-1 HiFi will. If you want to go up over this boost pressure up to 20 psi or more, a larger turbo is in order as they have the efficiency up there at the neccessary flow rate.

Many RX-7 people just hit the 400 rwhp mark with T66 turbos at 15 psi. Some do a little better. A 60-1HiFi (the small one) can get up to about 425 rwhp at 15 psi. That makes it a better turbo for that boost level. What it does lack is the efficiency to push it much higher and this is where the larger turbos start to gain the advantage. This is why I like it. I consider 15 psi to be my personal street limit and 400 rwhp is nothing to be ashamed of. There is no need for a larger turbo on the street.

 

point taken, but that example is wrong. even though a 66 doesn't really wake up until you're almost in the 20's, it'll still put out more at 12-13+ than the 60-1.
