Turbo setup Route n54

[henrydavison]

Hey everyone, I cant get myself to stop reading about turbos and the most I read the more torn I get on which route to take regarding turbos.
What turbos would be the most cost effective for a reliable 600-625whp, I dont beat on my car but I have fun time to time. I like the price of the v3 VIV 19ts and see very mixed reviews from being saying they have no issues and others saying they only lasted 1k miles. I love to go with pure stage 2 High flows but those are very expensive, Ive also read only gopod things about the Hydra turbos and they look well priced, but I havent seen that many reviews. That beiong said, should I just shell out the money for a good set of new turbos if so which ones? Maybe a lightly used set of good ones to save money? Are the China turbos now good? Need help, I'm going insane
Current parts: 7.5in VRSF FMIC, BMS Charge pipe and BOV, Catless DPs, NO secondary Cats, DCIs, Have the following but not installed. Stage 3 x2 450 walbro LPFP which Hobbs and wiring, Motiv Reflex LITE, 2in Inlets and Outlets, ekpm3, and I will be buying 750cc Port injection. also might buy flex fuel wiring and sensor if needed.

If you want twins RB turbos are the best quality.

In the 600hp+ you really want a single turbo setup but you wont get the down low torque of twins.

Hail Hydra!

Know a few people running them and not one failure.

That's a good setup you have so far, I'd say the only thing missing for right now is just installing one of the 450 pumps you have, then 2" inlets + outlets with whatever upgraded twins you buy. If you're going after an upgraded twin setup you want to watch yourself past 600whp, running a twin pump + port injection for full E85 may put you in that caution zone only because the TT's love to generate lots of torque, especially early-on in the RPMs. Unless you're smart with your powerband and don't get on it until ~4500rpm then your chances of failure are lower. Otherwise, the majority of stock-motor N54 owners run that fueling setup with a single turbo.

19t-sized turbos can get you nearly 600whp reliably with just a ~22psi E40 map, no twin pump / port-injection needed. That's what I've been running daily on my Viv V3 "6+6 Blade" 19t's for right around a year / 10k miles now with no smoke or wastegate rattle at all. On a warm day at the local DynoJet last summer, it put down 533whp and that was with a botched tune containing bad fueling hiccups + lots of big timing drops, which the tuner even admitted it robbing me of ~50whp. Ever since then, I switched tuners and should definitely be around the 580whp mark now with how my boost and timing is dialed, along with zero timing corrections or fueling hiccups anymore.

As much as I can vouch for the Viv turbos, I'm sure people will say otherwise. But, the same could go for some who have ran Pure's for 30k miles and others who'd write a horror story about them after 5k miles. I was in the same boat and just took the chance with the Viv's, but made sure I was as precautious as I could be by making sure to do a vacuum test on the wastegates before install, priming them with oil before first startup, and then from there just making sure the oil is up to temp before doing any pulls along with ensuring no boost leaks / restrictions so they don't have to work extra hard

I run this set up on PS2. No issues.
You gotta pay to play.

Are you running the High flows or regular stage 2s?

I've been running a set of TPC Stg 2 turbos pretty hard on 24lbs of boost for the last year and have not had any issues with the turbo. Spools quick and makes good power. I daily this thing on e85 w/ drag radials and the rear end will step out on me if I'm going any slower than 80mph... SilentN54 is running the same set @650whp running mid to high 9s. Price point is around $2500 shipped if you use SilentN54's discount code.

HOWEVER, I would advise you to go with a single turbo kit. You'll thank me later because you'll get the boost bug and will eventually want more power. Buy once cry once instead of forking all the money for twins and then having to redo/rebuy everything.

Hail Hydra!

40k miles of hard use and I had one wear component issue (silicone outlet pipe) which was unfortunate but updated on future designs by Hydra, and one weeping turbo seal that just started recently, but that's a nitpick. I think that's pretty good!

Better reliability than my factory mitsis which physically failed totally in that same mileage window and then developed wastegate issues on the replacement set within the next 40k miles on the car.

Don't need to go single for the boost bug. Fairly confident I could run my setup well north of 800 as is if I ran E85. Though, I don't agree that anyone needs more than 600 on the street. Personal preference is 550-600 on readily available pump gas and power to the ground.
