How much more power is a t3/ to4e 60-1 going to make over a te/to4E 57 trim(.63a/r stg3 whl)???????
big difference or what, in general??

earl

A real 60-1 w/T4 exh should make 75-100whp more than avg t3/t4. Spool will be slower, however.

Earl just gave you the answer. What else do you want?

boosted hybrid

The 60-1 t3 is completely different beast than the 60-1/t4 (the standard 60-1). I would say expect probably 50whp difference over the t3/t40e that you spoke of, maybe more. I know that the 60-1 t3 will make more power in the higher boost levels than the standard t3/t4oe variety, just how much more depends on tons of factors (displacement, head flow, compression, tuning, etc). Just look at both of the turbo's side by side and by shear size alone you can tell the 60-1 outflows the t3/t4.

We should get Stoopid into this thread, he has alot of experience tuning/driving 60-1 t3's. From what i read he almost exclusively uses them on all the customers cars that he builds. Now if he just will see this thread...

i was looking for the answer that boosted hybrid gave because as he stated the t3/60-1 is different than a t4/60-1. that is why i ttt'ed it.

it wasnt a very descriptive answer. I myself would like to know this as well. From what I have seen the 60-1's dont really make more power then the T3/T04e's until around 20psi. I dont know if they are T3 60-1's or T4 60-1's either.

SiRkid

thats why i made this post
I want to know if I should get a t3/60-1 or a staight t4 60-1 if I decide to get one of those turbos instead of the to4e .

I will tell you this, if you already have a T3 flanged manifold that you know you want to keep I would just get a T3/60-1 with a .82 a/r exhaust wheel that way your turbo is witholding about the same amount of power as the streight T4 unit.

But just be aware that with that bigger wheel you won't behitting full boost till you get up to about 5800rpm or 6000rpm depending on your downpipe and exhaust size.

my t3/to4e 60-1 which came from majestic will support 550 horsepower at 22 psi. they were coming out with a new wheel which would add another 50 horses to this but i do not know if it is available yet

Everyone speaks of what should happen theoretically but I did pick up 100whp on the dyno by making the change from a 54 trim stage III t3/t4 to a 60-1 all else being equal.
Now theoretically, it seems that mating a t3 exh with the big 60-1, the two sides would fight each other. The 60-1 would push all kinds of air but would then would get bound up by the t3 exhaust and build way too much backpressure and put you on the wrong side of the surge line on the compressor map. Am I wrong about that? Won't be the first time

Stock@$$GSR

What RPM was full boost for both of those Turbo's for you? I'm assuming that going from a T3/T4 to a straight T4 has to be pretty damn dramatic.

earl

Tough question to answer as we don't have data logging yet but educated guess is 4500 and 6300 rpm

i have a quick newbie question...so if you just replaced the turbo with the bigger 60-1, will you get more power even at the same Boost? or is it just able to handle more boost, therefore enabling it to make more power? sorry about this...haven't thought about "just turbos" a whole lot before..

thanks,
mike

earl

That question will bring more opinions than any other question. Bigger turbo will make more whp at same pounds than a smaller turbo.

boosted hybrid

Like I said before, we need Stoopid in this thread...he has alot of experience with these 60-1 t3's and i know that he would have all the answers.

MikeMAN

okay, thanks guys :D so for example...i buy a greddy turbo kit for my 1998 ex....lets say i am running 5-6psi and getting 160 whp.....now if I throw in a bigger turbo and run 5-6 psi still, and putting out like 200whp...is that same level of boost still safe for my engine, even though the power output has climbed?

thanks again!

BTW: how many posts do i need to be a freakin' member :D

was the switch to a t4/60-1 or a t3/60-1

Thats what I am wondering also

How can you compare those turbo without even considering the exhaust wheel? I am not a turbo expert but this is what I know.

TO4E/T3 57 trim major diameter is the same as TO4E/T3 60 trim, the difference lies in the minor diameter (inducer). Those two wheels are very similar but the 60 trim will obviously make more hp, but that depends on the exhaust wheel and housing.

You can do some stuff like add a TO4S 60-1 full size, which has a totally different compressor wheel and housing (4 inch inlet) and much bigger housing. Some people, but not many have adapted this compressor housing and wheel onto a T3 exhaust wheel and housing.

Now there is a third turbo TO4S 60-1 full size with a T4 exhaust housing and T4 wheel. There are multiple combinations of exhaust wheels and housings. This the big boy turbo, similar to what is found on many 9 second cars.

So it would be difficult to exactly predict the characteristics of each turbo. You will need to find someone that can match a good turbo for each application. A bad fitment can really suck and bigger isn't always better.

Which turbo were you speaking of?

OK guys, I can tell you in our race car when it hit full boost with the t3/t4 and the 60-1 since I drive the car. We have our VTEC switch point at about 5500rpm. It is basicly hitting full boost at this point with the 60-1. As far as the t3/t4 it has been awhile since we ran the turbo on the car. And everyone needs to remember this is on a full race car/full race motor so street driving cars may act a little different. About 4 grand and the t3/t4 54 trim turbo and it was spooled.....Mike

earl

Went to T-4. No experience with t3/60-1.

rondigs

How functional is the t3 60-1 on a (fully built LS/V) daily driven car. If your not hitting full boost till 5-6 grand that doesn't leave alot of rpm for top end power. FFgeoff uses this turbo(t3 60-1) exclusively on his projects. Wonder how well it works on the street...

SiRkid

should work fine..just have to wait for it to spool..... it will be like a typical honda..nothing down low..up high is where its at.
the t3/60-1 wont work with a 1.6 will it? it will be out of its efficiency range?
