i currently have a t3/4 .48 a/r 50 trim.

debating if i should keep this or go with something else for my goals.

i want the quickest spooling turbo that will get me to 8000 - 8500 with ~400whp.

im not just looking for HP either. i want some decent torque

i was looking at the sc32 and sc50's or just getting the turbo i have with a 57 trim.

any suggestions

bump for some info

USDM 4G VTEC

i can always get this one;






just kidding....

IMO the SC50 should suit ur needs

platinum00

haha, i want the top one.

what is the primary differences between the turbo i have and the sc50

platinum.

quicksol95

why you get a tubro so damn small

lol
j/k the hell is that turbo off of

USDM 4G VTEC

the SC50
Precision's line of T3/T4 turbos for Sport Compact vehicles comes standard with Precision's TA31 style exhaust housings with a 5-bolt discharge side in A/R's of .48 or .63. SC50 comes with T31 wheel with either a 2.559" Inducer and 2.121" exducer (69 trim) or 2.559" inducer and 2.229" exducer (76 trim) Available with or without internal wastegate. Each turbo comes with a 360-degree race bearing center section and a T04E compressor cover with a 3-inch inlet and 2-inch outlet. Larger T04S cover with 4-inch inlet and 2.5-inch outlet available at an extra charge. SC50 has a 54mm compressor wheel that has a 2.123" inducer ans 3.000" exducer (50 trim) Supports up to 450-hp at the flwheel with proper tuning.\


as u can see the trim level will allow a better flow (depends also what trim u get) at top end
this kind of turbo spools full boost around 4800 rpms.... wich will give great top end... IMO i will get something with a little better mid to top end power... like what u got....

remember once u start pushing over 330whp... u will start the traction issues, and on the st will be a pain

platinum00

yea for sure want something with some mid power. im most likley not going to run on the street with 400whp. just nice to have on the track with some slicks.

so you saying the turbo i have will give me a little better mid rev power, and the sc50 will be real nice up top.

well for your need it also depend of the psi that you want... my tuner doesnt want to tune a street car with 91 octane over 15 psi....

Think about it too... to get your 350+ whp you will have to boost like 25 psi ?? Do you plan to boost 25 psi on pump gas ??

Your T3/TO4E 50-trim is the exact same thing as a PTE SC50, only the PTE turbos use PTE's own Turbine housings, which are a little bit ported IIRC. To make 400 WHP I would step up to a .63 A/R exhaust housing.

so if i just get the sc50 .48, that basicly is not going to do much for me over what i have. and if i got to the .63 a/r that is going to increase my lag and take away from my midrange power band which sucks for the street.

i hate to have my engine built to **** and back and only run 300 -350 whp. but it looks like that's what i might be doing.

how about this GT28RS. it seems to spool real nice and has great TQ numbers. but i think it max's out at like 300 ;(

I honestly think that just going to a .63 A/R on that turbo is not going to be enough. Even for the D16.

There's one individual that has used a GT35 (though a bit large) with a fully built d-series motor and is getting some good results under 15psi. Give me a shout, I believe I have a few turbo alternatives you can use from the Precision Line..

platinum00

so far from what i have noticed. the GT28RS has the best powerband.

is there anything that will give me a similar powerband with just a little more HP.

Twin T88's...

jk GT28 or T3 60-1 is my vote

kabaroo

sc50 .63 a/r, seems like that might be an option. if i recall "yellowturbo" is running one on his d16?

i plan on using a SC50 .48a/r on my mildly built d16...

jmal1919

Have you thought about going with a slightly larger setup but in ball bearing configuration. That way, even with the potential lag of a larger wheel, the spool time may be the same as what you have now, or even less.

yellowturbo is runing the sc50 .68, and he mentioned he wishes he went with the gt28rs. so that's why im kinda woried about that route.

yellowturbo. what are you reving to. i think im going to go 8000 -8500 so that might help me out a bit.

the SC50's are non ball bearing right.

what would you suggest.

Ball bearing turbos really don't make much of a difference, a couple hundred RPM's at best.

A .63 A/R 50-trim should be capable of 400 WHP. We made 370 AWHP (on an AWD dynojet) at 19 psi on a friends DSM on pump gas with a 50-trim in a mitsu housing which is smaller than a T3 housing. On race gas and 26 psi we made 430 AWHP, so unless you have blown seals or something, 400 WHP in a FWD configuration should be very attainable.

platinum00

its not the problem of getting to 400whp, its usable powerband.

400 is really easy with my setup. but i want this beast to be nicly streetable. ( power below 5k and torque )

He uses the .63 AR same as me. I thought the next size up is .82 ar. He reves to 8200 but doesn't make power that far. Think his graph peak around 7800rpm. Don't get all hung up on what power you want. Drive your car first with 300whp and then decide if you want more. Believe me, it plenty fast on the street with teh turbo you have now.

It shouldn't take 25 psi to make 350whp with that turbo.

Hey Platinum,

Since you were considering my turbo i'll post a link of my dyno graph which I feel has very strong mid-range power (for the D series).

For anyone that isnt aware, it is a .63 exhaust, 54 trim, SC32



at 5k rpm i'm making 160whp and 170wtq. On other dyno runs I was making about 180whp and 190wtq at 5k rpm.




Maybe this will help,

platinum00

that does not look to bad.
how much boost was that on, and what motor.

depends on the motor setup and tune i'd think. remember ar fab's d16... did 400whp @ 32psi or something like that on an SC50.

platinum00

on what kinda gas.
32psi is really high.
