I'm piecing together a turbo kit right now and not sure as to what turbo to go with.
I've seen alot of people happy with their garrett t3/to4e 57 trim, so at first thats what I was leaning towards getting.

Right now im going to boost a stock gsr motor and hope to get around 300whp, but I have a gsr longblock in my backyard on a stand that I plan to build (bore,forged internals,ect) but I just dont have the money to do both right now and I really want to go turbo soon.

So my question is should I get a sc61 and run it at 7psi on my stock motor until I get the built motor done and then I can use that turbo to get alot more out of it. Or should I get the garrett t3/to4e 57 trim and run it at about 10 psi and have better spool for now but I will most likely have to ditch it when I build the motor and up the boost, or will I be good on that turbo til about 450??

Also will 7psi on a sc61 get me around 300whp? (specifically a Precision SC61 a/r .70 rear housing .63, because some guy around here is selling one)

 

If you're on the stock bottom end, there's no reason to get a turbo like the SC61. That's totally overkill for your goals. There are people making over 500whp with that turbo. I would go towards the 57 trim or a variant of it. I know that TheShodan still carries the turbo i used to use...the GT3255b. Its a smaller version of the 57 trim that spools faster yet still has the power capability you need...

 

honestly get the 57 trim now and upgrade to something much better than a SC61 WHEN THE TIME COMES. it may sound like a waste money but its really not

or get a HX35 and change the exhaust housing thats a cheap solution to get what you want now and later

 

I have a sc61 i started using this turbo on a stock b16 made 305 to the wheels at like 11-12 psi. now on a built gsr it is making over 500 hp. I can tell you the sc61 turns into a beast after about 12-15psi on the stock motor the spool was not that bad. I been there done that and had no regrets!!! Good Luck!!!

 

The spool wasn't bad?? On a stock B16 you should have full boost around 5-5200 rpm whereas my GT3255 had full boost (11psi) at 37-3900 and still made 315whp. I dont see why you'd want to buy something significantly larger than necessary at this point.

I dont know about other people, but i buy turbos that fit my setup. I've had 6 different setups now and about 4 different turbos. I think that when its time to build the motor and upgrade the setup, you can upgrade the turbo. For now, get something that fits your needs and goals...plan for the future when the time comes. Also, with the new turbos on the market, the SC61 isn't the end all anymore

 

me personally I buy things so I don't have to buy things twice. the sc61 was good on my street setup and on my drag car it is running strong. I plan to push the turbo and car to see if it can run a 10.10 or 9.99. there is not much left really maybe about another 4-5 psi then I think it will be overspinning the turbo.

 

To the OP, what kind of powerband are you looking for? What kinda driving do you do? is this your DD, or are you gonna drag race it or a little bit of both?

I agree with Tony on this one.

 

Daily driver, I drive to school and work everyday about 50 miles round trip. I will probably go to the track like a couple times a year if im lucky.

 

Well if that's the case, error on the small side. The last thing you want is a car that only has power at 5k+ for a DD. I loved having full boost at 3800rpm on the street. If you want, i can post up the dyno graph and show you just how streetable it really is...It might sway you towards the 57 trim or even something a little smaller

 

ok OP look the HX35 is about the same as the SC61 compressor wise. BUT you can get different exhaust housing and limit power that way. plus its more affordable.

if you wanna rape people on the street use your 9cm^2 or 12cm^ exhaust housing and make 300-450 wheel hp.

if you wanna be a demon at the track use your 14cm^2 housing or 16cm^2 housing and make 450-600 wheel hp.

 

Thanks for all the help guys, yeah Schister i would appreciate it if you posted your dyno graph.

 

Here you are

 

Get the SC61, you will like it.

Spool isnt that bad

 

that graph looks good. i've never liked 57trims. power fell off on the top end. i would race my friend with the same set up by the same tuner. i would pull him on the lower end and he would kill me up top. i will sacrifice spool on the lower end to have a strong top end.

I defiantly did not need a t3t67 but when it was tuned the motor loves that turbo a makes good power with and a good spool.

I vote sc61 if you only have 2 options. otherwise. Adams power band looks really good. or the hx35.

EDIT: 7psi on a GSR motor you will not see 300. It really depends on how efficient your set up is. My turbo at 9 or 10psi saw 300 and that's a t67.

you live in DFW let tony tune it

well if I get the garrett 57 trim I will boost around 10psi to hopefully get around 300.

Yeah I am getting it tuned by Tony

the SC61 and HX35 are very very close cousins and make about the same hp. the biggest difference and advantage goes to the HX35 becuase of price and upgrades. performance is about the same.

 

then HX35 all the way. IMO not a 57. you wont be happy. that is from experience and my personal likes. I think back and wonder why did i even buy those turbos....i know why becuase of people say spool time. screw that. I cant feel it anyway.

 

i have a sc61 on my b20vtec stock daily drivin and i like it alot made 284whp at 10psi full boost is at about 5000 but i still like it

 

i made 341whp on a stock b16 at 8 psi with a gt3076R.

 

Way more choices than the 2 turbos the OP listed. *tsk tsk*

haha atleast i kept it close sc61 &lt; hx35

 

^^ True.. Very True

 

This is with a t3/t04e 60trim, pretty much the same as a 57trim.

pump gas (91oct) 15psi...


112 oct at 20psi


I think its an awesome turbo. I am going to try to up the boost until it stops making power. I still think it has more in it. I'll will try to get my best E.T. on this before I step it up a little to an SC61 or similar sized turbo but for now this is more than plenty.

As you can see from my graphs my top end is still pretty strong at 8500+rpms. This is a stock port head too! I might have something to do with the setup but its not much different than most on here.
