Mr.DC2TurBo

Here is my situation, I have NO money at this moment for pistons, rods and install but I do have enough to upgrade my turbo.

My plans are to run 10-11psi on stock b18b motor with a bigger turbo but I don't know what is the difference and will these give me the same hp at this low of a psi?

Here are my choices: 1) Garrett T3/60-1 w/.63 A/r turbine (TURBINE SPECS:T3 .63 A/R housing, HIGH FLOW 76 TRIM stg 3 wheel, 360 degree) or 2) Garrett T3/T4E (.63 A/R housing, 60 TRIM, 360 degree)

Which one is better for my setup. My GOAL is to hit ~270hp at 11psi on stock interns. Will this be possible?

My setup right now:
rev hard manifold
t3/t4b
440cc injectors
s200b
power extreme 2 exhaust
a-vcr

Mr.DC2TurBo

anyone?? also, anyone know when I would hit full boost on these turbos? remember I have LS so is this worth it?

redboost10

on number 2 youll hit boost probably around 3500-4k rpm, thats all i can know

.63 T3/T04e.....or maybe look into a .60/.63 T3.....good turbo for the money

Mr. Softee

both too big

too big?? what should I go for? I was afraid it might be.

sc32 is a good turbo, easily capable of mid 300 whp.

is this good on an LS and what is it compared to the t3/t4e or t3 60-1?

Mr. Softee

like a 50ish trim .48 a/r would be pretty efficient at 10-12psi for an ls motor.

I have a .48 a/r right now and ppl keep telling me at 10psi ill only make around 230hp but ppl with t3/t4e would make around 250+ with the same psi. My goal is to get the most out of my stock interns as possible without blowing it

Mr. Softee

um the a/r is just your turbine housing. what about your entire current compressor side, that is far more important in determining peak power.

also area under the curve is more important than peak, especially with ls motors that can be generally overly peaky from 5k to 7k.

id keep your .48 housing and just make sure you pick up a compressor wheel that is comparable to like a 50ishtrim t04e wheel.

not sure exactly the trim. When I bought my rev hard kit I didn't know there was a difference in turbo so the only info I can remember is that it was a t3/t4b. Anyway to find it without taking my turbo apart? I never dynoed my car bc I didnt want to pay twice for the tunning until I make sure what turbo is good for my LS.

Mr.DC2TurBo

I read some where that ppl prefer t3/t4 60trim with .63a/r i believe. I'm just afraid the lag will be too great in a LS when compare to gsr or type r where they can rev pass 7K. so would u recommand a 57trim with .63 a/r for a LS?

bigwig

.48 T3/T04e is a great turbo for an LS...but some of the T3s arent too bad either. .60/.63 can do a good job on an LS or a "super 60" T3 also can do a good job. if you have a turbo out of a revhard kit i think they are .48a/r 50 trim .60a/r compressor house...i think that turbo is great w/ an LS....honestly...i think you should be able to make more than 230 w/ that turbo....

no, thats still a little too big for 10-12psi.

bigwig

.63 ar on a t3/t04e can be okay if you have 3 inch DP and exhaust...but you are going to have a lot of lag and maybe 2000-3000rpm of boost...it will pull like hell and you might get a higher WHP number but all in all...its not the best turbo on a 100% stock B18b1 block....all in all i would say my first choice would be a t3/t04e w/ a 54 or 57 trim .48a/r...2nd choice would be a T3 .60/.63...the T3 will pull damn hard aswell and has a bigger efficency range and is cheaper...but isnt as powerful as the t3/t4.....its all what you want. also a "super 60" w/ a .48a/r and a .60 a/r and a 51 or 54 trim...i forget what they come in....arent too bad of turbos for the LS either......

I would stay w/ the turbo you have now. its fine. dont listen to what everyone tells you. dyno tune it w/ a good tuner and if at 11psi it gets 238whp and you want 250...turn the boost up....LS can boost a decent about as long as its well tuned...

Mr. Softee

my ls put down over 250 at 10-11psi and i had a 57 trim, but the powerband wasnt desirable. i had no power until 5000 rpm, showing the poor choice in turbo. I could have easily have made 250+whp and had usable power from the late 3000s and up if I would have appropriately chosen my turbo.

Mr.DC2TurBo

I just talked to my installer and he still believes the Garrett T3/60-1 w/.63 A/r turbine will make some nice numbers on my car and that I should hit full boost no later than 4K. My question is why do you guys think this is way too big for an LS turbo? If I hit full boost around 4K i'm still pretty much in the pw range and it's not too laggy. Let me hear some inputs on why I shouldnt get this.

Mr. Softee

full boost at 4k LOL

your "installer" sounds a little misinformed.

I didnt hit full boost (10-12psi) until about 5k with open 3" downpipe, equal length manifold, and a 57 trim E.

In all honesty it sounds to me like you want the biggest turbo possible, and are ignoring the truth of the matter. All the advice you need is in this thread its up to you to make the non-riceboy decision and get the right turbo for your application- something hardly anyone does becuase its far more fun to gloat about having a really big turbo like 9 and 10 second cars.

with a T3 super 60 i get full boost at 3500 ( 9psi)

bigwig

i agree w/ what 94goldjungsr is saying. Seriously your installer is full of ****...if you are boosting 6psi you might get full boost at 4k rpm...but 9-12 psi you are looking at 5k plus. like i said before you are lucky to get 2500k rpm of boost and its going to be all top end which kills the thing the ls has going for it....the low end torque. I think the t3/t04e is a little over kill for sub 300whp....but it handles very well regardless. since you think T3/T4 is the greatest **** in the world...buy the .48a/r atleast....personally i would be looking at a nice junkyard turbo that is oil and water cooled that is a .60/.63 or a "super 60" which is .48/.60...either turbo is cheaper and perfect for an LS. i dont think there is anything else we can say to change your mind. the choice is yours....you have our advice....now its your call.

Mr.DC2TurBo

94goldjungsr, you make a good pt but the turbo I have right now is probably a .48a/r and it doesn't seem to pull really hard. The Garrett T3/60-1, is that the same as a super t3 60? If so 3500K at 9psi is pretty good.

99lspwr

Well most people will bash this comment....But the greddy 18g is working out very nicely with my b18b in my 92 h/b...If u choose this it will work great for what u are trying to do...The car has a very usable torque band from 3-7k...definetly a very fun turbo for the street, and puttin down some decent 1/4 times on 11-12ish psi..

Mr.DC2TurBo

What is the difference in t3/t4e and t3/t4b? I really dont no the spec of a t3/t4b but if I have a .48a/r my trim should be either a .50/.57/.63 right. so what makes my turbo so different than a t3/t4e which has a .48a/r? Sorry for the totally noobie question.
