and well i'll still have the 0.82 so ill see how i like this for the while
let us know the "seat-of-the-pants" difference!

I heard today, that Slowboy racing has a wicked set up comming SOON! can't wait to see THAT! GT35R, as well as every other "flavor".

i would strongly recommend switching back to the .82 and upping your 2 step to make more boost off the line. The problem isnt the turbo, its that you have too much traction for the car to not accelerate fast enough... if that makes sense.

bump the 2 step up, make 18 psi at the line, launch the car and then let me know how the car did

it makes a tonnn of sense actually!
i should have indicated in my previous post that I'm using just a SAFCII....i know..sad! even at 5200-5500rpms i have bogged.

but standalone is my next step and would most likely be AEM. but i've already ordered the next back end..but it's no prob...i will try it out for the while and someday(soon hopefully)when i do have 2 step launch control capabilities, i will get the 0.82 back in there.

thanks man

I have a 4 bolt turbine housing... will cutting it to put a V band for the downpipe affect performance? Btw thanks for all your responses.

Its easily available and fits a wide range of turbo kits. 4 bolt outlet is ideal as 5 bolt is more on center (Doesnt flow as well) and doesnt fit nearly as many applications.

That being said, in the coming year, i expect the GT3567R to be more popular as it will exhibit identical spool characteristics with the same boost threshold, yet be capable of even more power. This turbo is very sensitive to proper turbine housing size and is very rare, but is amazing what can be done in the t3 frame
If spool is good on the 3567 does it make sense for me to go with a turbo like that over a .82ar 35? I am currently building a 2.3 bottom with a Pauter machined crank, pauter rods, JE stroker pistons, fully built head, Piper race cams, and AEM for managment. Have you found a really good manifold yet?

Isn't this the same turbo that Topspeed used on there 761awhp run?

Which 4 bolt turbine housing do you have? If you have the 3" outlet 4 bolt housing, its perfectly fine to cut and convert to vband, just make sure you preheat the housing before TIG welding, and using a high nickel rod is an excellent idea.

if you have the 2.5" outlet 4 bolt housing, i would recommend not converting it to vband, just get the proper housing

I would definatley prefer the 3567 over a standard 35R, particularly since you have the 2.3L. The larger displacement will definatley benefit from the increased volume of air. Going to a big turbine housing is also worth considering on that setup.

Our manifold would work very well with this motor/turbo combination.

Are you saying I should look at a 42r (gulp)

We haven't seen a difference in power going from a .63 to .82 AR on a 35R. Even on our 2.4 motors we don't think it worth the trade off. I am also interested in testing out the 3567R this year along with the 42R.


Geoff, do you think you can make the same power at the same boost level with a 40R versus a 42R? Just wondering because we are in the process of doing (2) 42R kits for customer cars. We have done the 40R's in the past, but they were just off the shelf units. I know when we talked at Sema you said something out about the turbine housing being a problem with the 40's.

What is a 3567R? is it a modified version of the GT35R? I haven't heard of this turbo. who has one? any feedback and/or dyno graphs? is this the new HOT turbo? The 42R is too big to go to church with correct? I hear you have to take the AC out for that anyway. I cant see spending all that extra dough for the 42R, which is 60-80 more AWHP. I wouldn't think it would be practical unless you use it for DRAG ONLY. correct? Thanks for all the great input, and I am glad to see you on here chatting RNR! Keep talk'n the turbos, you are helping alot of us decide which way to go.

The 3567R is a 67mm compressor wheel instead of a 61mm wheel that comes in the 35R. Garrett recently released this new turbo. The 42R can work with AC as this is what we are doing with my car. It will make a heck a lot more power than 60-80whp more, but at a huge price tag and expense. I wouldn't really recommend it to anyone looking for a street car.

Thanks for the info. do you have any of those in stock? 3567R's? does it help with boost? more streetable I assume.

In theory it will be laggier than the 35R, but make more power. I don't know of anyone that has them in stock. I could get one from Precision probably pretty quick if you are interested.
