For my ls motor, and gsr trans swapped 97 hatch i was advised to get a T3/T4 -57 tim .60 comp .63 exhaust by numerous people when i mentioned my goal of 250whp tuned with Crome Pro or hondata. Stock internals for now, and a full 3'' exhaust.
Some mentioned to expect a full spool time at 5k? Is this true? So that means if im running say 8lbs boost i wont hit 8lbs boost until 5k when my motor redlines at 6800?
If thats true what other turbo should i look into? I prefer something where i wont have to constantly hit redline to get some power, but also be able to lay down some good numbers. After i get all the turbo situated and out of college ill be building this block, or swapping it with a GSR motor but still use the same turbo setup in a 300whp car.

 

i will say 4500rpm fullboost at 8psi

 

When I had no exhaust leaks I had full boost on the same turbo at about 4300.

 

sorry for my lack of knowledge but whats the difference between the t3/t4 and the t3/to4E?

 

i think its the compressor housing

if you have the money and want something that will spool quick
i would get the gt28rs

that would give you a really nice powerband

 

between 4000 to 4500

 

I you want to stick with the t3/t04e, then get a small turbine houseing, the .48 AR one.

I personally would get a greddy 18g. You would probably get full spool before 3 grand, and you will be able to make 250 easy on that turbo.

 

i have a .48 ar housing on a t3/t04e 54 trim comp and i get 14 psi by 3200 rpm. i wouldnt trade the power band for anything. .48 ar on the ls is freaking sweet for a street driven car

 

with the .48ar i shouldnt stick with a 57 trim?

Im just lookin for a turbo that i can hit 250whp just at the track ever once and again on a stock internal ls, but still have room for improvment when i upgrade or go GSR motor and dont want it to fall on its face revving to almost 9k.

thats got 57 trim .63 written all over it.

i had it on my ls, 10 psi by just about 4500. upgraded to an lsvtec and it still pulled real hard to redline. dont bother with the .48. when you shift at 7k with a gsr tranny you come back into gear at like 5200rpms, so you will be spooled with either exhaust, but make more power with the .63. trust me, ive been there

 

ok, not real turbo savy here, only ever been in one other car that me and my buddy swapped which was a 240sx with sr20det, which spooled at about 3k fully, maybe a little under.

But ill still be making more power than stock even though it wont be fully spooled correct or no? Like is it going to be major lag up till 4000-4500 then pull like mad?

 

no it shouldn't be that bad...at least i hope not! I'm going to be using a T3T4E 60 trim .63AR on my GSR and i'm looking for full boost pre-4500rpm (8-13psi depeding on the day)....looking for around 240ish daily and 300+ at the track on the stock engine!

 

running same trim in stock gsr @ 5psi and it would reach 5 psi @ about 3800 or 3900rpm, 4500rpm turbo would spool really loud.

 

f22b1 here...
LSD Motorsports Mini tubular manifold
Garret t3/04e 48/50 a/r 57 trim stage 3 wheel.
Full boost by like 3300 and it pulls HARD till 6300.
268 whp/273 tq @ 10 PSI (daily driven)
ALL STOCK internals

Daddy like, and reccomend. ditch the 63 and go with the 48 if you want a more usable powerband (My opiNION)... This thing is reallly really fun with power just about everywhere. Spools quick and I cant keep my tires hooked up stabbing it in 3rd from a roll!!! And its in a cd5 accord.

 

Thats something more what im looking for i would like to be fully boosted at about 3500. For my ls motor at least since stock redline is at 6800. If it was a GSR that i could revv stock to 8100 then that would not be bad at all fully boosted at 4500.

So many turbo options here its hard to make a choice really. I guess if i ever went and did the gsr swap i could always upgrade my turbo and sell this one. I wont be doing the gsr swap at the soonest until after college so the LS will have to do.

Then again with my gsr trans in 4th gear at 4k im doin only 60mph...on the highway i dont want to be in full boost all the time.

So im still torn between my original 57trim .63, or the 57 trim .48

Go with the 50 trim or the 60 trim, if you look @ the comp maps the 54 and 57 trims poop out b4 the 50 and 60 trims do. I haven't ever plotted an ls engines flow, but for what you are doing you should be fine with these. Also if you are looking for faster spool, and go with the smaller a/r you should use a boost controller so that you don't just sit there and spin your tires. Or get a good ems and solenoid to boot. It doesn't matter how much hp you put to the wheels if you cant hook up.

And ls' engines are known for torque, that means traction issues.

In reality for what you are doing pretty much any of the t3/t04e turbos will do you just fine. GL.

 

didnt know that, so the .48 in pretty much any trim is kinda what im looking for huh?

 

Its kind of weird but this is the same thing im looking for once I drop my ls in. Im still debating too which trim to go for. either a 54 or 57 and the hotside. need more researching

 

it would probably be easier if i knew how to read the maps, but im pretty lost when looking at that. It dosent help that every other tuner/ person / thread i see reccomends a totally different turbo.

 

you will be happy with a .57 trim!! (unless you want super fast spool up go for a smaller turbo)

 

The .57trim on my B20 spool is definetly later, but it pulls HARD up top. Ive had lots of cars beat me off the line by 4 or 5 lengths and I think that Ive lost the race. Then I hit 15psi in 3rd and walk by them like they are standing still.... Trq steer @ 65mph = crazy tryin to keep it straight. If you do a lot of stoplight to stoplight racing, this isnt the turbo for you cause by the time you hook up you'll be to the next light. If you do some longer stretch or freeway racing.... This is definetly for you. Corky Bell once said: "If you have no lag, you have no trq increase to look forward to."

I hate lag but love getting full spool.... Its a love hate relationship. lol

I dont really do much street racing, for the fact i cant afford to loose my liscense and besides my old GSR i never had a car that owuld last against the worked 3000gt's, 5.0 stangs and some built srt-4's.

Just looking for that extra umpfffff really and take it to the track every once and again. The people up here who typically street race are the type that highway race or like 30mph rollers.

I have that exact setup. I will post up some datalogging runs to show you the RPM and what boost I am pulling when I get home tonight.

 

running 15 psi and losing 4-5 lengths off the start? who you be racing or is it traction control? the .57 trim or even .60 offers a lot of top end power and once that turbo is full boost, it will pull hard to redline. i've been in smaller turbos where it's the other way around where they spool really fast and hard and then don't seem to pull at high rpms. 3.8krpm @5psi i wouldn't say it's too late of a spool, besides 60mph on a stock gsr tranny is like 3krpm and it doesn't take much to hit full boost.

 

There is no way that you will run out of turbo on any of these t3/to4e turbos. Any trim will do you just fine, the smaller the trim and a/r the faster the spool, you WILL have traction issues. You only want 250 so they wont be horrible, but you will have them. All of these turbos are good for 400+ hp.

Your engine only flows 13.8lb/min (assuming 90% eff), and even @ a pr of 2.02 (15psi of boost) you will be right in the sweet spot of most of these compressors. You don't need to worry about running out of turbo.........believe it or not, ur choice.
