    i dont have the ability to tell you that answer, but i know that the people who can will need to know what youve done to the engine and what psi do you plan on running.

    What size turbin housing is on the T70? Why not get a T4 60-1 with a .84A/R?

    i think the only diff. is the t70 Has A 70A/r and the 60-1 has a 60A/r what would thew t60 come in at.. my car spools the t3/t4 up a 2300 lugging it

    If you opt for the larger turbine housing that will help to kill the quick spool up. Unfortunately I dont know the math to find the exact numbers for you.

    The A/R of the compressor housing wont effect it too too much, I believe its the turbine housing that controls most of the spool up characteristics.

    ALSO, on your T3/T4 are you using a .48A/R on the turbine housing? It sounds like it since you're getting such a quick spool. Maybe .63 or even a .84 on that turbo would be better for your needs.

    no need for an .84 housing, .63 housing will do 600whp

    Its not the power he's worried about, he wants a longer spool time.

    yeah i need a little lag... but i would like it to come in around 35-4000 rpm
    at this time i am running 28 psi on my gsr and with that turbo it just breaks the tires loose as soon as i launch ... but do you guys think my car will be able to pull that big turbo?

    What size turbine housing do you have now on the T3/T4? Prolly a .48, it should be written on the housing somewhere.

    i think it is a .48 id have to check when i get home...would my car be better off with the t70 or t60-1... i am looking for around 725 hp.. i am use to all motor and kinda new at the turbo thing but i have a full built GS-R and i am gonna run the full race top mount mani... with 4inch exhaust

    what size turbine is better for a honda.. my fried has some turbo on his hatch GT 4088-R or somthin like that..

    i want a turbo that is a little over kill but not so much that it takes me until 5000 to spool it.

    A GT series has a dual ball bearing center and will spool up quickly.

    T4 60-1 running 25psi should do the trick. 725hp is a lot of power to try and reach.

    Either will work fine. The T70 seems best with those details.

    The .84 and the 1.05 are the size of the exhaust housing. The larger the number the larger the turbine housing. The larger the turbine housing the longer the spool but with better flow.
