My concern is my motor is built for 10k, is the .48 a/r going to run out of its effeciency zone?

I would hate to get this turbo and have to swap it out later. I am shooting for 350whp

 

I don't know if it's going to still have anything left at 10k for you, but I love mine to 7800rpm.

Why set an rpm goal? Why not just stick with your hp goal and rev to what you need to. You can make 350whp with that turbo without revving to 10k.

 

future plans

I'd like to "turn it up" a little on slicks, and so i don't have to shift to 5th

Honestly, yes, with that particular motor, hp goal, and setup that you have, the 50 trim T3/T04E or B with the .48A/R will seriously lose efficiency after about 380, and that's when its pushed pretty high. The way that the VTEC head flows (which is wonderful) will cause additional heat issues.

This is where you would want to look at something a bit more efficient on both the turbine and compressor wheels, and not simply a "change of housing" issue.

 

I would definatly go with the .63ar on your application since it will be a high revving engine. I dont think that you will need to go to 10000rpm but im 100% sure that you need the .63ar.

I have a SC50 .63ar on my D16Z6 and this turbo is really made to be used above 5000rpm just like your engine so it will be the perfect match.

Mine is for sale btw but I would prefer to sell it to someone local.

 

If you are gonna be spinning your motor 10k do a .82a/r hotside or at least a 63.

 

why not look into the Sc34 the .57 trim over the .50 trim SC50 they make alot more power up high

or a SC61 for that matter

The 50trim is a good turbo to say the least.

SC61 is way too big for 350whp.

 

I'd like to get your turbo...things just won't allow it right now

I think i am going to swallow it and pick up the sc4431e with BB for 850$. It seems better suited for my goal and still in my 900$ price range.

I was trying to hold out for a gt30r...but, i am impatient

 

SC34 all day

 

I in no way wanna sound ignored. But if the Cost of the SC44/SC34/SC50/SC61 is the same. IMO, It would make enough scene to get the SC61 just incase later down the road u want more power.

Even a ball bearing SC61 would spool pretty nice, He'd prolly be crapping his pants by 4500RPM and still have 5500RPM of PULL to go

 

^^ u have never been in a car with a SC61 that lag is bad man, it doesn't make **** power till 5k and then it's like nothing but tire spin if your runing over 12 psi, it hits hard, but the lag is there most def

Ive rode in a few actually. My friend had a 1.8L GSR with SC61 and it was getting 10psi by 4500RPM. At 10psi he was making alittle over 290whp on 94 pump gas..

But either turbo in this thread will make 350whp.

 

There is a reason Precision makes the smaller turbos and not just the SC61. It's so you can size the correct turbo for your goals. Throwing the biggest snail on your engine that you never plan to use the full potential of is a waste when you could be spooling faster and going faster.

well said dude !

 

You won't need to rev anywhere close to 10k to make 350whp.

 

^^ that's true. i believe most people just rev to stock i think i'd go with a sc34, but whatever you prefer

 

Pick a turbo inbetween the 60 trim and the SC61 like i did, FR T3/T61! Still has better spool than the SC61, but cranks out more power than the t3/t4 60 trim

 

Thought at all about a GT30e or GT35e non-ballbearing? Even though they dont have the BB CHRA, they still use the superior housings and wheels than their T-series cousins. I've been *very* impressed with the results from the GT35e in particular. Sure, you sacrifice a little spool time, but the price can't be beat (I can lay my paws on both GT30e and 35e for WELL under your budget)

You're right, but with a 4.7fd i do need to rev that high to not shift to 5th gear in the 1/4

The sc61 sounds to much like the t3 60-1 i ran before, 0-4500 = 28.8 dial up....45-9000 rpm = t3 fiber. I could never hold traction on the street...i want something with less transition, smoother onset...eg: gt30


I used to have the gt3251e non BB, it was nearly perfect, i just can't find them anymore

There is a gt3076r for 900$ but it's internally gated, are new turbine housings costly?

peak powerband will likeliy be around 8krpm with .48 a/r.. i'm running t04b 50 trim w/ .48 ar stage 2 wheel. it peaks ~8k.. so probably around 7.5-8krpm if pushed all the way.

Get a taller tire.
