? about GT35/40R
I recently purchased a new HKS SS T04R manifold for use with a T04R. But I'm leaning more towards a GT35R, possilby a GT40R.
I just don't know and haven't been able to find out if the HKS manifold has the correct flange for the 35 or 40. Does the 35 use a T3 flange and the 40 use a T4 flange? Or can they be ordered with what I want?
Thanks!

You are correct in your assumptions. The GT35r comes standard with a T3 flange and the GT40R comes with a T4 flange. There is a T4 turbine housing available for the GT35, but it flows the same as the T3 footprint and is an open valute (non divided). A-Spec has been working with Garrett to come out with a true T4 turbine for the GT35R (has the volute volume as a T4 instead of just a T4 footprint and I believe it will be divided). Who knows how long it will be before they are available though. I'm sure Zero R will comment (A-Spec guy)

Carl please stay out of the 35R threads as we know how much you hate them The housing is a TO4 divided, it is not a T3 housing with a T4 footprint like ATP currently sells, it is Tang. unlike the on center others are selling. And they are true Garret turbo's not a "version" some other places are selling as the same thing.

So some that sell the "Garret" GT35/40R is not really all Garret parts? Well that sucks!
Will any GT35R come with a T4 flange or just yours Sean?
I would really like to try to make my own setup, as I have the tools, welder, and some skills .
I'm also trying to learn about the turbos and what kind of flow I want for the power I want.

You going to give me a ride in your car when you get the new turbo in and what not Attila? I want to see if how much of a difference whatever you get is over the stock twins. I am thinking either 35R or 40R. If I put a supercharger on my Miata instead of a turbo then I might as well go 40R.

No any GT35R wont come with the T4 flange you will have to order it, wether you can get the one I'm going to sell from other Garrett resellers, well let's just say I'm working hard to keep mine with me. But I don't own Garrett so who knows what the end result will be. I will say I can beat anyones price on them that is for sure.

A 35R will probably be my Autocross turbo once it gets the T4 housing you are refering to. So the volume, and geomety of the ATP piece is the same as the T3 footprint? What about the one from PT?
BTW, I only said they would not make 500rwhp on a 13B, so far no one has proven me wrong

The volume on the ATP is the same exact thing as the current T3, PT turbo's are not the same as well I have had them side by side and they are different, now maybe the one I saw was optioned that way but it did not have the same size compressor cover the wheels looked slightly different as well but I wasn't "allowed" to pull the turbo apart to take a good look, I think the one we have will be a nice fit between the 40R and 35R T3.
I haven't forgotten the 500whp either,again I never made that claim.

Well, I only want 400 RWHP ...
So a T4 GT35/40R will give me what I want for a very quick responding turbo. Since I'm still a n00B33, what AR, trim, (and any other acronyms) would be the best for the turbo?
->dunce cap on..
Also, I thought that you (Sean) only sell the turbos in your kits. Are you saying that I can get one through you optioned with what I want, and try really hard to build my own setup? Maybe if I fail miserably then I can come crawling back and get the rest of the kit from you.

Attilla, a 35R is a fast spooling choice for 400rwhp, but a little small for that HP on pump gas. You have to go to 18-20psi IIRC to see that HP(not O'k on pump IMHO). A properly sized TO4S/R might be a better choice if you want 400 on pump(~15psi) Sean...?

Ihor made what looks like close to 460 Hp with his old 35/40 set up. I am not sure what fuel he was running was but it was on 20psi.
In comparison here I linked the dyno graph of that run with 1.00 a/r T04R @19PSI
and a Gotham Racing GR67 1.00 a/r also @ 20psi.
Of coarse tunning, fuel, air temps etc are all unknown but still a nice comparison.
The 35/40 seems to make better power down low.

The dyno numbers look really nice!
However, I don't plan on running more than 16psi on the street, and for track 18.
At 16 pounds, I'm sure it won't be anywhere near 400 whp, but that is okay with me. Would using them at 16 pounds be too low for the GT35?
Dare I say that I also want some semblance of reliability? That is the primary reason I am choosing 16 psi for street driving.
Carl, you said a T04R may give me more of what I am looking for at 15/16psi. What about responsiveness? I really like the way the GT35 can spool quickly, and it does quite well up top. Again, I am not looking for ultimate HP, rather an overall great responding turbo down low and have a good power curve.
So when does the lesson start about how to choose the best A/R, etc. for what I want?

I would talk to sean about the various ARs available on the 35R, and at what boost they make good power. There are alot of 35R/3540 dynos, try a search. Alot of turbos make ~8-10hp/psi until they reach there optimum efficiency, then you may see as much as 20hp/psi. my point is that since you have a very specific goal, and boost, Sean should be able to match a turbo to your goals very accurately. as far as the TO4R(pt67), a .81 p trim will get you the HP at the boost you are talking, but at the cost of low end response. So, in retrospect the 35R properly sized may be a better choice(not neccessarily the 1.06.
Most all components are reliable, it's the individuals set-up that may not be

I have a gt35r A/R 1.06 very fast spool. full boost by 3500. Im still waiting to get it fully tuned and dynoed. I have heard that 450 is posiable at 17psi with very good tuning
