Most Reliable Twin Upgrades

syntax · 12-23-2021, 10:37 AM

I know answers will vary, I would like to upgrade my own turbos and stay twins, nobody will change my mind don't bother suggesting single. Im looking to have 500-550whp, which is fully achievable even on small ebay turbos. What I would like to ask is suggestions for the most reliable and long lasting twin upgrades. I wouldn't mind buying Pure 600's and keeping them down at 500 whp. Ebay turbos will definitely be more stressed and pushed after some time compared to Pure 600's at only 500 whp, as they are better quality and are known to have higher power capabilities. So let me know, the price and "stage" doesn't matter. I would just like to know who has lasted the longest and how much power they've been making for x amount of time. Thanks!

I was thinking of twin upgrades with power capabilities closer to 600 hp for when I decide to up the ante in the future.

I was thinking Pure600's for a while, but wanted to see if anyone had long term issues with them over other brands before pulling the trigger. This build will prioritize reliability over anything, would like to keep it detuned and dump more money into maintenance. Going to be redoing OPG, VCG, Waterpump, rear main, belt + pulleys, OFG, etc. you name it.

We have been offering Pure600 for years, its a reliable kit

I personally know someone who has RBs GF 17t for about a year making around 600whp on full e85 without any issues. I know it's not really long term, but those turbos haven't been out very long. I will say that the quality of RBs are far greater than those typical eBay turbos especially with the enlarged turbine housing.

I believe he is also looking for reliability. Aren't the Vargas product bad when it comes to that?

Vargas are known for unreliability,

The only reliable twin upgrades are RB and Pure.

Yes agreed, that's also my conclusion from my research around the forums. Furthermore all the bad customer support stories with Vargas is another reason not to.

I have been talking with Rob these past few weeks and am purchasing some RB Twos, they are a great option that can easily run 500-550whp on a light ethanol blend or meth. The Twos Plus could probably hit those numbers without breaking a sweat on 93. He's great to work with, and I have heard nothing but great things.

I've had RB GF at 27 psi and it's only at 50% WGDC it's no where near maxed out and Rob encouraged me to push them further, but I rather keep things safe. RB hands down is the best and my next option would be Pure Stage 2 standard and/or high flows.

big_ed · 12-23-2021, 01:35 PM

I've had Vargas Stage 2+ since they released, running them at 28 psi with full e85.
Ran them for 50k miles with no issues except for some rattle after some years.... But that's what stock frame turbos do.
Just had them refurbished/rebuilt out of precaution and they are solid.
I'll prob keep these on my car forever if they last another 50 and can get rebuilt again.

E90lmao · 12-23-2021, 02:07 PM

I know of one person personally who went with Vargas turbos and has wastegate rattle within less than a year of running them, sorry I don't have the miles on them though.

Currently running Vargas turbos going on 40k miles. Has rattled since installation. Mike or whoever the guy is everybody talks to says rattle on the turbos is normal and to adjust the wastegate actuator with MHD...which introduces turbo lag...and didn't even work! Horrible quality control. PLEASE avoid at all costs.

I always thought the wastegate actuators were supposed to be adjusted before installing by pulling -5.9inhg of vacuum and that's where they start seating and then around -6 -7 is when they should be fully closed. But yeah, I'm definitely avoiding Vargas myself.

He was referring to the wastegate rattle fix function within MHD. Which is not supposed to be needed on brand new turbos.

Oh yeah definitely not needed on new proper turbos

big_ed · 12-23-2021, 06:12 PM

Been on this platform since 2012 and the consensus is that stock frame turbos will rattle eventually due to the type of waste gates used.

Tbh once you're pushing that amount of power you will prob have a loud exhaust or a single mass flywheel making just as much noise as the rattle.

Safest bet if you don't want rattle is to get a single turbo.

Face-palm, He's selling new turbos with wastegate rattle?

MHD wastegate rattle fix introduces lag when it works,

So what he's saying is... Enjoy brand new rattling and laggy Vargas turbos

Lmao.

VTT should stand for Vargas Trash Turbos.

New turbos should have no rattle, unless they are Vargas Trash Turbos lol.

In all honesty, I knew the general consensus would come down to Pure and RB. I was hoping to hear people argue over the two of the most prominent brands who deserve "Tier 1" titles in the terms of twin upgrades in terms of reliability in order to make my personal decision. Precision used to have poor quality turbos back in the day compared to the quality they output today, but this scenario won't change that I have decided to pass on Vargas for now, at least in this present day application.
Would love to hear people argue over the higher output options of the RB's and Pure 600.
