I am at the turbonetics site and i have decided on this

HC-TURBO 60-1 Hi-Fi TURBO ASSY. BIG SHAFT - BALL BRG. 1,493.00

but a bunch of options are available

NOTE: All standard 60 Series turbochargers include your choice of O or P trim turbine: .58, .69, .81, .96 A/R “on-center” turbine housing; dynamic or carbon (except “Big Shaft”) seal; wet or dry bearing housing - specify when ordering. 1.30 A/R “on-center” and a full range of tangential-style Turbine Housings are available as options

It is for a street application 10-14 psi mostly with the occasional few higher runs, I am looking for around 350 - 400 for the wheels, that being said which options should I go with? O or P trim? I was thinking .96 a/r but I don't know about the rest of it. I was looking at the hks standard manifold and hks standard wastegate (14.2psi spring) to go along with it. I don't know what to do, but I gotta decide quick before dad finds out

I have everything built up already in prep for the turbo, greddy 2 row, e6k, 1600x2, fluidyne rad etc.

Seems that most people get the P trim turbine. What kind of manifold are you going to run? divided or non divided? ( I don't know what the "standard hks" manifold is.) If you get a divided manifold I'd deff get a divided tang/divided turbine housing to match it. If you get a collected (non divided) manifold I'd get a regular tang/undivided turbine housing.

If you want to run as low 10psi you need a spring that will be at or lower then 10psi. The 14.2 psi one won't allow you to run any lower than 14.2 psi before the wastegate starts to open.

Suds,

I have a T60-1 Garrett turbo...For starters I woudln't mess with the ball bearing turbos....I had one and it was off more than it was on. My spindles keep'd warping and the wheels hitting the housings....ugly! anyway,

I got a .70 compressor w/ 1.00 A/R turbine. It puts out 400-475 depending on boost etc. I would recommend this turbo to anyone. Its great at the track and still streetable....

I would consider the 1.15 A/R if I were to do it again but for auto x the 1.00 works great..... Also the HKS manifolds are superior in quality. I have the tangential divided model... Keep us informed on what you decide....

i've got a Garret 60-1 P trim .55 front a/r and 1.32 rear a/r with a divided housing. i dont have in installed yet so I don't know what type of power i'll be putting down but so far everyone seems to think it will be a good turbo for my car. At first I though 1.32 would be too large but my motor is streetported so I think it will be ok.

I'd suggest P trim with 1.00 a/r for your application.

Thanks for the replies everybody!

not 1.15 as brad has considered?

Rotarys (while prone to blow up) amaze me with the amount of exhaust energy they produce. Us Supra guys usually stick to the .7 A/R exhaust... if you're feeling really bad-*** you get a .81 (or .96 if you're racing with nitrous).

1.32?!?!?! I don't think it would EVER spool on my car!!!

Have fun... the 60 sounds like a very fun turbo.

bkapold@aol.com

My motor is street ported and the 1.00 spools pretty fast....full boost around 34-3600rpms @ 18-20psi....Its not the fastest spool I've seen but it happens so fast I don't have time to care, because I usually looking at guages.....Its nerv-racking
Prone to blowing you got that right, but I have 6 hard years on this motor and I want to see how much abuse it will take, because its days gotta be numbered....hope I'm wrong

1.32 A/R ...thats pretty big. My friend has that on his 3 rotor....I'm not much of a drag racer but when that kicks in you better hold on...let us know how it runs...cool?

I bought the 60-1 Big shaft turbo P trim from turbonetics.com for $1100, and 40mm 5.9psi hks wastegate and hks manifold, oh and a kaaz lsd

What should I do for oil lines?

setzep

What a/r ratios did you get and what manifold did you get (undivided or divided)?

For the oil line, you can make your own with adapters. did you get a wet center section or dry?

bkapold@aol.com

I actually used the stock top oil feed line and tweeked it in place of the T60-1. The flange pattern was the same and it was easy to do, so why not! The bottom dump I went to a Diesel repair joint here in MPLS and found one to fit the bottom turbo flange. Then I bought some somewhat bendable braid'd line going back to the motor. I did have to cut the little "S" tube on the dump side because it got kinda tight....
I didn't get a coolant turbo. I'm pretty patient on letting it cool down etc. No problems as of yet anyway...besides if the bearings go bad any rebuild shop will do that turbo for 200.00 and less why should I care?

I have a 1.15 A/R with a P-trim hot side, and it spools fast enough for me. The engine is also street ported.
