ok, i am a turbo newbie, so go easy on me. i have searched and this is what i have come up with.. i will try to be as specific as i can with my goals.... and then perhaps someone can offer me some advice.....

i have a 96 ls integra that is a daily driver..... i am looking for a turbo that will make good power, and will spool fairly quickly... because it is a street driven car and i want the boost to be responsive.... i plan on keeping stock internals and boosting at about 8psi. i would like it to remain a daily driver with the odd 1/4 run... hopefuly hitting mid/high 13's. the motor is pretty stock right now... the only mods that will remain when the turbo is installed is an ACT HDSS clutch and an apexi N1 catback.. ..

from the research i have done.... i think my goals would be fulfilled by a t3/to4e with a fairly small trim perhaps 50. as far as a/r i am pretty lost. could someone shed some light on my questions. is the t3/t04e a good choice? what about trim size and a/r?

i hope this thread takes of for i am interested also

t3/t04e served me well.

I had it on my stock gsr motor for a year and it was fast, full boost by around 4300rpm. Specs were .57 trim compressor, .63 turbine. I feel that trim is perfect for street and great pull on the freeway.

just as a referance for my turbine side i have a .48 a/r stage II and i hit 6psi by 2600.....hows that for quick spooling. downside is less top end which will hurt your 1/4 runs.

JM Performance

i have the t3/t04b s-3 which is a decent fit. for an LS i think the E 50 trim is the best.

as for turbine side...it depends what you want. if your gunna race a lot then bigger than mine would be better. i drive my around town....i like coming around a turn, gunning, then resuming normal speeds, so the super fast response is really nice. all depends on what you want.

2lowintegra

^ so let me get this straight then.... a larger turbine side a/r will provide more top end power... but at the sacrifice of lag and reponse... if that is correct then what is the next size up from a .48 a/r on the turbine side? and what is the benefit of the t3/t04e as oppposed to your t3/to4b

JM Performance

correct. next size up is .63 but you can also go up to a trim III. I think going up a trim makes a more pronounced difference, and changing the a/r is more like fine tuning

2lowintegra

ok. so are you using a 50 trim... or are you recommending a 50 trim? what exactly are your specs....and what are you recommending...(since i recall you saying that a to4e would be better than your to4b..)

JM Performance

uh i think a E 50 would be slightly better but they're both good. I'm running the B S-3. compressor w/ .48 stage 2 turbine.

2lowintegra

great thanx. so then would this make sense.... a t3/t04e 50 trim .63a/r &gt;&gt; would spool a little later than your set up, but would make a little more top end..?

instead of all this jibberish and getting confused, just read

^ thanx man, i already read that... but i'm not sure that the answer to my question is there, so if you know it.. please help me out...

intekragsr

Just get a t3/to4e, .50 trim compressor, .63 a/r turbine.

The way an LS head flows, that would be your best match. Great for street, great top end. Done.

2lowintegra

^ perfect, that as my suggestion, so i was on the right track!

there is an odd ball in the T04E family.
when we see .50 trim, we assume it flows less than the .60 trim
that is not the case

the T04E .50 trim will work for an LS, but it will be more efficient if were using a well ported head, or stock vtec head (puts you right in the best efficiency island).

Take a look.. compressor maps for the T04E family: http://www.turbofast.com.au/FlowTO4E.html

.50 trim actually out flows the .54 and .57
I think of it as a .60 trim with a surge line that allows you to spool at a lower rpm.
You can ask VaporTrail about the T04E .50 trim, he has probably seen quite a few on the dyno.

I personally would go with the T04E .46 trim if I had a stock LS. It is efficient from 10 to 23 psi. (stock 1834cc; stock head)

^ hey man, thanx for the info and link.... i had a look at those compressor maps...and i am not sure how to read them.....but it looks to me like the .50 trim flows very well, more than .54 and .57 but it seems to mak more top end then th .46 while flowing at approximately the same rate...... am i reading it correctly? if so, the .50 looks like a good choice
