im looking into a new turbo setup. i have a brand new stock ported motor coming in, and i want to get 400whp by 14-15psi. i am either thinking a pt67 dbb .81 a/r, or a gt35r t4 .84 a/r. i know there is a good size difference between the 2 turbos but i am trying to compare responce vs. output between them. i want fast spool but i would like to reach my goal also. anyone here have a t66 or t67 bb? i would like to see the boost responce with the bb option. i had an rx6 turbo and i was used to seeing 12psi by 3k rpms. i would like to hit that boost by 3.5k rpms if possible. any imput appreciated.

 

You may want to look at A-Spec's GT35rs(500R) looks like it may be exactly what your looking for.

 

i was going to buy the 35rs, seems like it puts out the power of a t66, but a-spec is not selling the turbo seperatly...

 

I would say the 35RS(500R) from A-Spec as well. That will let you reach your goals without a doubt. Well worth the money spent considering how good their customer service is and that they offer a lifetime warranty on the manifold and DP. Just my .02 though.

I would run the GT35R. Nice turbo and we use them on several rotary setups with good luck, and they spool up quite quick for their size (61mm). We have some customers that swear by them.

 

ttt anyone have some more imput on this.

 

Another vote for A-Spec's 500R here. Great kit and it's made really good power for me.

 

I tried to order a 500R 2 weeks ago from Shaun and he would not take my order but told me he would call me back within a week,that was two weeks ago!!
Now he doesnt even return my phone calls,so good luck getting that turbo.

 

I was in A-spec's shop a couple days ago. Sean is very busy working on getting kits out the door. He had a delay getting Tial wastegates, but I think hes got them now and is busy making manifolds for the kits. Send him a PM he WILL get back to you. I think its about a 4 weeks wait on the kits.

 

I just wish you could buy only the 500r turbo..

 

Well since you're sticking with a BB setup, I suppose a AF61r is out of the question. I am also interested in the 500r. Aaron, whats the deal man? Are you ever going to be done with your car... I know when it is done it's going to be a monster... but damn... lol.

 

35rs?

 

35rs = 500r

 

The reason I asked for the dyno graph website is because I thought there was gt35rs graph on there. I just looked and it isn't there. Also, I thought I remembered a thread in this section of the forum (maybe it was posted in A-Spec section), which had broken09s gt35rs dyno sheet posted. I can't seem to locate that dyno sheet and I swear I remember seeing it. Does anybody else remember that? or am I cracking up? If it was posted and someone saved it, would you please put it up here?

 

There was a dyno graph for the GT35RS in the original GT35RS thread. That thread has since been deleted and the 500r thread was created when they renamed the turbo. I suppose if someone asks for the dyno sheet in the 500r thread that he will repost it. He does have video of some dyno runs in the 500r thread that show the dyno graph briefly at the end.

 

I don't know much about the 35r but the pt67 is hot. I made 430 @16psi . I do not have the ball bearing one though. I have the .81 turbine housing. It makes 15 psi at about 4100 rpm. I ordered the .73 housing to get it spooled up faster. It's a nice turbo either way.

 

Yeah, its getting closer. Intake manifold is all done, motor's in the car, but the thumper hot side on the turbo won't fit w/ my intake mani so I'm just going to get it running n/a until I figure out the turbo situation..
