does a smaller hot side ar mean that it will spooll up faster?

 

yes it does, but be careful, our engines suffocate quite easily, and then your top end will suffer, and i believe if it's an extreme enough case you can damage things.

i'm not a pro at these things, but i saw no one had answered and figured i'd throw my 2cents in.

 

yeah i have a t3/t4 .so cold and hot .63 and i think its suffering really bad

 

wow! .63 T3 hotside is fuggin smaaaaalllllll! if i am forced to use t3 i try to run atleast a 1.0

 

well the t70 should make some good power then and to think i tear up turbo integras and sti's on 8lbs of boost no prob i cant wait to see the outcome. i have a friend with a 1.15 hot side and i do nt like the lag and how long the boost comes on at

 

Pardon my ignorance but is a T3/t4 larger than stock, or is it roughly the same size, just a more efficient turbo?

 

hmm i dont really know??? i just know it spools up really fast and it seems to act like i just have a high hp built n/a its always there with the boost but i hope the t70 makes a huge difference

 

if the turbo itself is small then running the small turbine housing isn't so bad. you get a larger compressor side on there and maintain the same little turbine and you will start to have issues.

nothing bad really but it becomes a choke. your top end won't be as strong as it should be and egt's start to climb.

just try it and see how it does .... oh and you should hang with sti's on a stock turbo

i thought this will be a good read.....

 

thsi motor i built is a 6port a crazy ported combined 6th and 6th ports adn welded to add no dead ends in the port 6port motor i want to see 400 out of this and i was just wondering if a t70 would be a good turbo for my app i would like a 35r or a 40r but its pretty spendy so here is the question how welll would a t70 work over my t3/t4?
