Hello,
I have 2 turbos in my hands and I am wondering which turbo I might be happier with and was wanting some opinions from all of you'll in here. Here are the specs on the 2 turbos I currently have. Turbonetics T3/T4E 60 trim .82 A/R Stage 5 Extrude Honed and Polished.
Turbonetics T3/T4 60-1 .63 A/R Stage 3 Ball Bearing.

Let the opinions begin and maybe I can get some advice from those of you'll that actually have one of these turbo's?
BTW, which ever one I don't use is already sold.......:D

I'm no turbo expert, but I'd say the .60 trim is to big for a street driven car. I also think the lag would be unbearable. As far as the 60-1, its probably the better. But I beleive 60-1 are To4b's. Correct me if I'm wrong Rob. To4b's flow poorly in comparison to the To4e. Turbomiata gained almost 50 ft. lb. of torque in the mid range by changing from a 60-1 To4b to a .46 trim To4e as per Rob's recommendation. I am only looking for a 350 hp or so application and my distributor was on backorder for the .50 trim, so I plotted VE on the maps of the .54 and decided to go the .54 trim in a 50 A/R housing with stage 3 wheel and extrudehoned .63 housing. I was hoping to have everything rollng for the convention, but I have had to work more than I thought (I work offshore) and havn't had time to finish. Hopefully I will have it running and dyno'd withtin a couple of weeks after the convention and be able to post impressions and numbers. Hope this helps.

I guess I really nevver gave an answer. My answer is sell them both and get the .50 trim with 50A/R and Stage 3 in a .63. Good luck!

Shaggy drives such a beast daily, and he's happy with it :-)

The 0.82 A/R Stage V turbine/60 trim T-04E compressor is a good turbo if you have to make 500+ hp, but if your needs are more modest, it is way overkill and you will have a lot more lag to deal with. On the other hand, Shaggy's car makes something like 365 whp at 16 psi boost on pump gas. Try that with a smaller turbo :-)

The 60-1 is the same wheel design as a T04B, but it is a larger diameter, 'scaled up' version of the T-04B wheel. T-04B's are usually in the 2.7x inch size range (IIRC), and T-04E's are 3". The 60-1 is essentially a 3" T-04B. This is a bad way to look at it, though. The 60-1 is a 3" BCI-2 compressor wheel (name for the design).

I think that Danny had a T-04B (2.7x inch diameter BCI-2 wheel), not a 60-1 (3" diameter BCI-2).

A T-04E is typically a 3" BCI-4 or BCI-8 wheel. The 60-1 will actually flow more than a 60 trim T-04E (either BCI-4 or BCI-8) at lower boost levels, but the efficiency falls off very badly above 14 psi. This makes the 60-1 pretty good for big displacement low-boost motors, but unsuited for high boost small displacement high power motors.

I agree, except that I would go with the 0.82 A/R turbine housing over the 0.63.

he is buying my 60-1 high flow .83 on the intake side and .63 on the turbine side it is a stage 5 exahust side. i made 424whp and 409tq at 20psi with pump gas. and i drove it daily, and never had any problems with it. spool up was incredible. on race fuel and retuning the tech it was over 510whp and almost 490tq.

Ok, my question is what T3/T4 sized turbo should someone go with to achieve 375-400 hp with a newer style BB DET, with S4 cams and one of Big Boost's intake manifolds. I would prefer something that is starting to make boost somewhere around 3500 rpm. Also I would really like to accomplish this without the aid of water injection or race fuel on 93 octane pump gas. Is this even possible? TIA

I don' t think this is achievable as the main problem is detonation.

Chris,

You might be a bit power hungry. I am not sure if you realize, but putting down 375 to 400 WHP in a FWD car can get crazy at times. I am assuming, that if you are wanting to run non race fuel, than you expect to accomplish this feat on the street. This amount of power will just roast your tires in 1st, 2nd and 3rd gear. You will have virtually no traction, and will most likely be zinging your rev limiter with reckless abandon. I think that a more reasonable goal, might be to get a setup that has 300WHP on pump, and 400+ on the strip. That is just my opinion! Maybe you are a STreet Racer and need all the HP you can get to bring home da, Skrilla and da hoes!

And to answer question, it would take a lot of praying and boost to make 400WHP with 93 Octane. I wouldn't reccomend it, because your engine might be able to do it, but it would be on the ragged edge.

Jim made 424 hp on 93 octane with is 60-1 turbo using stock internals and a Tec 2 stand alone. Is it possible? Obviously cause it's been done.

Actually the question concerning this type of HP comes from pure competition with my friends. It would be nice to have a dyno chart of this power, but the car would not be asked to produce it on the street, only on the track. I would like to accomplish that goal as sort of a bench mark. That's all, the car would usually tool around town around 300 or lower, depending on how much wheel spin I would be willing to accept. I don't want to live with water injection or race gas as my only solution. I am not willing to go to a Tec II set up initially but (if I had to) I am not afraid to go to it eventually(preferably when the Tec III is out with externally mounted coils). I would just like to know which turbo is comfotable around 375-400 whp, but could also be livable on the street at lower boost levels, where it would still be efficient and I would not be anywhere near it's surge limit. I just want a flexible set up that is really all. I didn't really want to rely on any crutches, but would accept them if need be. Thanks for the response guys.

would 91 octane be safe for a 300whp street setup, on a DET or maybe a turbo-ed DE? from where i live (so cal), the highest pump gas ive seen is 91. i know places that sell race gas, but honestly dont want to be running that every time i fill up, ill be broke so quick :eek:

U don't have to use a garret to make 500hp.

u can read up on this page http://www.forcedperformance.net/dsm_turbo_green.htm They have a bigger version called the red thats rated for 600+hp. A guy named Andre on the east cost has the green turbo and made 420hp at the wheels in his GSX on pump gas 93 with that turbo. Stock ECU no he has aftermarket fuel injection.

FWIW:

You can dyno 270's to the wheels( both hp and lbs) running race gas on a sr20det with the t25, water injection and a sds managment system... :)

aznvirus, as for the 300whp on pump gas, i did 320whp on pump gas with a t28.

Lyn Labahn, you don't need to pray for 400+whp on pump gas and alot of boost. nah don't think so at all. i made 424whp at 20psi. and had alot more where that came from, just ran out of the 550cc injectors. 510+whp is not power hungry, its called quater mile tuning on a stand alone program that you can load at a click of a mouse then back to the normal program after a run. and your right everyone is entitled to your opinion, os please don't think i am coming across as a jerk, i have no intention of doing that.

Chris Colburn, you don't need water injection to make big numbers. you just need the right tuning/tuner to set up your car. and have all the right parts working together. well i have all the tech 3 software on the way, and i am itching to get it, and all my new goodies together to see what kind of numbers i have coming out.

PNWser, i think 270whp *** race gas, water injection and management i feel is very possible. however the t25 will definately have a short life.

yo mike collins, you da man

Wish we had 93 on this side of the country, we get 91 pee water
:( good #'s jim let us know how that TEC3 software works out.

Yellow4g63, thanks. yeah i will definately let you know how the tech 3 software is. i also have a protech manifold and sleeper motorsport t4 turbo as well as 1000hp fuel pump, matching fuel filter and my jun 280 cams waiting to go on my car. bryan and aaron from sleeper are going to fly over here for 4 days or so to tune my car and street race. bryan and aaron are expecting hugh numbers from the new set up. we will have to wait and see. i am buying a d-cam this weekend and once the new dyno chart are take i will post them for everyone ot check out

Do u have the Knock Sensor hooked up on your TEC unit? damn didn't know they made house calls lol good shit.

i am not quite sure if it does have a knock sensor. i dunno if they make house calls. i told bryan and aaron i would pay for their flights to maryland if they would do some work and tune the tech on my car. they are staying here and eating at my house cause i didn't want them to be in some b.s. hotel.

Jimbo,

No offense taken man! I forgot about your setup, and your numbers are very very, impressive! I think that without stand alone engine management, and a T4 it would be pretty hard. None the less, apparently it can be done. How is the lag with the T4? Any times at the strip? Broken any trannies?

good deal, make a vid with your car on the dyno I want to see that manifold glow redhot.
