I searched and came up with nothing.

Has anyone gone single turbo and regretted it?

[SlimE92]

Not sure if serious....

[blaster3500]

I have seen a couple people regret it. For the most part I don't think so. I think the biggest complaint would probably be o2 issues.

[JM98]

Pretty sure anyone with a Jpworkz kit has some regrets

The only regret when going single is the lack of money in your wallet after

Completely serious. My biggest concern is changing the powerband.

You wouldn't have many issues as long as you keep a conservative powerband.

Let's say you get a turbo rated for 750hp, if you keep it below that threshold it'll last you longer than someone pushing that same turbo at 700-750hp all the time.

Overall from years of reading these threads and other forums it seems that the people who regret upgrading turbos are the guys who get hybrid twins over the single turbo guys since they can't seem to last long with companies coming out with different "revisions" every week.

Me personally I'm going single top mount soon..

I used to be against single turbo because of the "lag" you hear about. I was 100% set on twins and making the most HP I could. I went through a couple sets of turbos blowing before I finally couldn't take it and decided to just go single because at this point, reliability was more important that the lag issue.

First single turbo kit was a ACF top mount with 6266. It wasn't my cup of tea. Open dumps are annoying and sound dumb. To much stuff has to be moved around. To much heat up top where it shouldn't be. O2 sensors required removing the turbo. Overall was just a mess. Sure it worked but I wasn't comfortable with it.

Next kit I went with Speedtech 6466. Overall everything is awesome. Some parts of it are cheaper but tbh it is parts that don't matter and if you wanted you could go buy more expensive parts to replace it. But the overall hot side of that kit is perfect.

As far as the lag, I have to say "What lag?". It really depends on the tuner you have. The 6266 top mount was hitting 20 psi faster than my twins. When it comes to single turbos I think Motiv is the best in that game.

Curious what twins you were running when they blew?

Do you guys who daily your car with a single turbo kit actually get to enjoy all the power? If so, do you have a radar detector? Personally I'm starting to doubt my ability to enjoy owning a high HP vehicle in the area that I live in. Traffic is shit and cops are most likely hiding around somewhere. First week I got my car I floored it up to 85mph getting on the highway and got pulled over.

I think that would be my regret, going ST and not being able to use it. I also have an 1990 twin turbo 300zx with upgraded turbos that dynoed at 489whp so I'm kinda tied up with two pretty fast cars rather than one monster. Would probably have to sell the Z if I wanted to go single turbo.

Do the single turbo kits have a lot of lag before the boost starts to build? That's the one thing I like about the twins....next to no lag. I've been in some single turbo LS cars that had horrible lag......it took a few seconds before the motors started to make power. That sucks for a daily driver.

That's what I've been wondering. Even with 400-ish HP at the wheels, it's hard to really use much of the power.....unless I'm wanting to do something stupid and/or get a ticket.

For those of you who are making 700-ish HP.....can you even get into the throttle much on the streets, or do you mainly drag/track your cars? I've thought about doing a single turbo.....but I think for a daily driver, it's kind of a waste of money except for the few times you might actually get to use the power.

Depends on how you tune it...

[woodex m.e.]

i think the only regret was not buying a car in better shape before doing the conversion. The drivetrain is solid, but a lot of little stuff had to be replaced due to corrosion from where i live. Also the body is fairly beat. Now i have this monster awd car that pulls like hell, but looks like a clapped out pos. Function over form as def the motto on this build.

I had much more fun with my stock turbos with tune/exhaust at 375whp than over 600whp on mmp twins.

I'm sure there are a lot of people the feel that way. On the dragstip....awesome! On the streets.....it just can't be used much.

[Jeef]

If you drive in the correct rpm, there shouldn't be any lag. If you want to stomp on the car at 1500 rpm and expect instant power then of course you'll be disappointed. Even upgraded stock frame turbos have noticable "lag".

Doesn't matter if you are 400whp or 600whp, the car will still be fine to drive at light throttle. When you lay in it for a WOT pull is when you feel the big difference.

[Torgus]

I never regretted it. As said above the people who regret it probably tried to cheap out with the JPworks kit or some other cheap kit like the On3 where you have to replace everything and then you have spent as much as a DR/ACF.

My ACF single turbo sounds fucking amazing, pulls straight to redline, haven't burnt up an 02 sensor yet, zero heat related issues, and zero gold reflective tape lol. A single turbo will make more power on pump gas than any twins will. Most of the country does not have E85 access. If you want to make power on pump a single is your ONLY option. If you want the most top end power a ST is your only option.

Yes it's fun making gobs of tq down low for hooning around town with the stock twins. Even upgraded, but with upgraded you probably want to tune out some of that rod bending low end tq anyways unless you have a fully built motor(10k) that will not break when it's making 600wtq at 2.5k rpms, but can your car actually put down 600wtq at 2.5rpms and have traction? I will still take the single turbo any day of the week. Is there lag? Yes, but if you downshift like a normal person you will be just fine. The STs are highway monsters and their power comes on much more linear vs. twins and is easier to drive and MUCH more predictable when you put your foot down to have some fun.

Also, you don't have to worry about the upgraded twins and a failure, so many horror stories and questionable vendors(VTT, DAW, Hexon, MMP, ASR, Frankenfuckup) over the years. It's $1,500 in labor when one of the twins fails + there is a good chance your turbo will not be covered under warranty. This is where the twin manufacturers have you by the short and curlies, you only have to buy one new turbo now and they will give you a discount otherwise it's rip it all out for a single or change to a reliable twin manufacturer(RB or PURE) which is $$$. It's 10 minutes in labor if my top mount turbo goes bad, you just pop the hood.

After you factor in inlets, outlets, and downpipes upgraded quality twins cost basically the same as a single turbo. A single turbo is inherently twice as reliable and can provide more top end power than any twins on the market as well as making more power on pump gas. Also, if you want to compare dynos of twins vs. singles do NOT use the vendor's dynos. No one can hit their numbers.

Wow that was well said Torgus. Personally I would ONLY consider RB's or Pure's for twin upgrades.

I agree wholeheartedly. Rob and the guys at pure have the best reputation and customer service to back.

[okayboomer]

I have some miles on my RBs and they're great but I do sometimes wish I went with a single turbo option. At the end of the day I didn't save that much money by sticking with twins and a single turbo from a good manufacturer has better further upgrade ability and serviceability
