is a t04/t3 a good size turbo to run on a ls with stock internals and upgraded fuel

 

specifics?

 

such as

 

Sure.

 

depends what your goal is. Top end power with turbo lag? Low end power with a faster spool but with lower top end? It all depends on what your looking for. But if you have the money, Id say a hybrid would be best, you can achieve an all around power band type turbo with reliability, but then again, if you have the money.

 

oh yeah, fergot to add.... when running high boost (which you might have the tendacy to do witha t03 or 04) you lean out your cylinders which means you have a higher chance of detonation (detonation= boom). Getting a a/f ratio controller or something similar is probally a god idea if youre going to run stock internals.

the above will help you understand which compressor to run..

information about turbine side: https://honda-tech.com/zerothread?id=153810

it wasn't easy to select which turbine to run.. since no formulas really available.. more like trial and error..

 

i couldnt do all the math too confusing for me but thanks Id rather go with a little bit of turbo lag and good top end w/ spool up at around 4500 or 5000

 

ahh.. found the link for the calculator that does it for you.. - thats only for compressor -

yes, we need specifics. what kinda t3/t04 are u looking at?

there are many too choose from.

for the exhaust you can have a T3 w/ either .36, .48, .63, or .82AR. you can then choose between a stage 2, 3, or 5 wheel in corresponding trims.

for the compressor you can have a T04 w/ either a T04b, t04e, or T04s housing. depending on the housing you can choose your wheel trim between a 40, 46, 50, 54, 57, 60, 60-1, 62-1, stave V, stage S, and stage H.

then you have "hybrid" hybrid T3/T4's like the "hifi" 60-1 which uses a t04e housing rather then the standard t04s. you also have precision turbo's which are also T3/T4's and then innovative makes a 55trim etc etc. lots of T3/T04's
to choose from.

the drag 3 turbo kit one i dont know what size it is exactly

 

well i have a t3/04e on my type r, 60 trim and 63 hot side.
the turbo is a bit on the laggy side, but keeps spooling up thru my whole rpm band plus . . . . so i dela with the lag to knwo i will keep boosting up top .
my friend with his R has the same tuerbo but diff trim , he has 60 trim with 53 hot side i think and he said it loses power 8k and up .
so it depends what your looking for.
