Advice on GTX upgrade
Hi all,
I am going through the single turbo phase but wanted your opinions on what route to go.
Just for info: I have a completely stock 13B, stock injectors, 3” full exhaust, upgraded IC and Rad setup.
So the options:
1. GTX3076 .82 A/R
2. GTX3582RS 1.01 A/R
Getting conflicting info. One tuner is saying the 3076 is more than capable for what I want, anywhere from 300-400. A second tuner/rotary shop is saying the 3076 is way too small and will have issues with back pressure, and the 3582 won’t be laggy and will make that power easily. Now I am confused on what route to go. I would be running dual WGs as well and upgraded manifold etc... all part of the kit but the decision is on the turbo.
What are your thoughts ? I can provide further info if needed. Thanks much
Cheers

option 3...
stock injectors arent going to work with either of those turbos and a gtx30 is too small for the REW. do they even come in a t4?
gtx35 and supporting fuel. if you dont upgrade your injectors then you will hit max duty as soon as you get into boost and then be asking for rebuild recommendations

Xpsi is not Xpsi.
I doubt you will be able to get a gtx35 to boost any amount without maxing the stock injectors. You NEED to upgrade your fuel system before running that turbo. Trying to tell you now. If I see your next thread asking for rebuild recommendations I WILL roast you like an almond and feed you to an elephant.

Get all the bits and stuff need it for the change first, man. Then get the turbo kit or put it together yourself. Keep in mind you cant just slap the new turbo and expect it work as plug and play.
what EMS are you going to run?
There is a lot of information for anybody doing this the best way possible. You have to Look it up , read read and read some more.

Fair enough cr-rex lol. I am in no rush to bolt up this kit, so changing the injectors and upgrading the fuel system will be done. Any recommendations for injectors? Not trying to make 600HP here, 300 - 400 and I am fine. Cheers

I would look at the Borg Warner EFR 8374 IWG as well. They spool as fast as twins and can do 400hp easy. Also built-in internal waste gate and blow off valve so you don't have those additional expenses and hassle.
May also want to read up/post in the single turbo section, lots of good info there.

the noise is epic lol!! I also have experience with Garrett so decided to stick with them. I read a lot on the Borg Warner turbos and they are definitely a fine setup, no denying that. Will check out the single turbo section as well.

The noise of an open dump waste gate is fun for 1-2 weeks then it gets REALLY old. But, I also started a thread on old man suspension 
.
Regardless I think you're heading in a good direction for a single setup.

. Again these are not daily cars so it never gets old for me! Lol @ old man suspension!!!
I appreciate all the advice from everyone. Heading in the 35RS direction. Upgraded fuel options as well. Still researching posts, videos, articles etc.

yes... my current set up is stock 550/1600. you will have to be careful with your boost level though. just keep an eye on your duty cycle. i would advise upgrading anyway though. no point in running a really nice turbo and not being able to actually use it because youre using "ok" fueling. you can stick with the twins for that

Thanks cr-rex, appreciate the feedback as always. What duty cycles are you seeing on your 550s ? Do you have a thread on your build, I would just go look there?
Will look into fueling further. And definitely plan to keep the boost under control and monitor the duty cycles

im running a power fc so it only shows collective duty and with that im somewhere in the ~60% range. i have a build thread but i havent updated it in many years. to get it up to speed with where i am now would be a tremendous task. i may or may not venture down that road one day

Thanks cr-rex, appreciate the info.
Thinking to run the IR Performance Fuel kit - with 750/2000cc. If anyone had experience with that kit please share. Here is a link to the product
https://www.irperformance.com/produc...n-fuel-system/
This kit does eliminate the FPD but has the FPR, I believe its Fuel Lab. Any concerns there?

the fpd is not needed. there is argument that it is but no real data proving one way or the other. one thing that is agreed on is that they fail and cause fires.
the fuel lab fpr is widely used and not a problem. anything you get from IRP is going to work

While it's true that many entry-level hobby setups can get away with deleting the FPD that doesn't mean that they aren't beneficial. Suggesting that there isn't any "real" information to support their benefit is laughably ignorant. Simply because you can't see a difference with your PFC doesn't mean it isn't there 
I have a sneaking suspicion that Andre has a slightly better insight on the subject than you do..

everything is beneficial in theory... where is the data that shows the benefits. ACTUAL benefits to keeping/adding it.
im looking for the data that he suggests exists in the video. i would like to see these oscillations causing actual issues and then the fpd fixing them.

I'm not an engineer, so I can't/won't pay to access this paper: https://www.sae.org/publications/tec.../2000-01-1086/
But it's safe to say this topic has been studied quite a bit. Since, as a result of these studies, OEMs see fit to run FPDs than I think it's safe to say they work.
Just because you're cool in a Dunning-Kruger world doesn't mean it's beneficial for everybody else to follow along.
As for tangible evidence... I'll be running a high-end ECU with pretty extensive data collection, along with a CJ rail that has the FPD integrated. Once my build is complete I may consider running some back-to-back tests with, and without, the FPD. Hell, I may ask my tuner for a rant on it as well and share the video. If anybody is going to have the off-hand knowledge than Shane will.

i would be forever grateful for that information. a with and without comparison would do the entire community good. cant say anyone else has performed the test, not that i've seen anyway. what are your power goals going to be? i would image, it would have more or less of an effect with varying levels of power. realistically, i would imagine fuel pressure and injector performance would be the largest factors.
