Maybe this topic has come up before and maybe not. I generally never do mods to my car that I cannot undue and resale before I sell the car. I am debating on upgrading my stock turbos to hybrids and I am curious if there is a resale market for either of these vendors turbos.

I would most likely pay the core charge, keep my stock turbos and put them back on upon the decision to sell my car. I have no immediate plans to get rid of my Z4 and I can see myself keeping the car for at least 3 or 4 more years.

Sorry, I am a financial advisor and I always debate these types of decisions in my own mind and I would like to hear some opinions from someone else.

There's a market but you'll be taking quite a bath. It's tough to trust hybrid twins - keep in mind at the end of the day they're stock housings that have been ported like crazy to accept a larger wheel combination. Factor in that your average user is pushing them quite hard....You don't see many RB/STG2 users at 480WHP, they usually go towards the bleeding edge. Reliability will suffer as a result, that's just the way it is.

What do you mean?

I mean the vast majority of hybrid twin users spin the turbos for max power. It's rare you see them being operated in "moderate" conditions. 520WHP from a set of RBs is pushing them. Will they make the power? Sure. Will they last? Probably not. There's nothing wrong with doing this, to each their own. But absolutely, the case-usage for most of these is going to have a negative effect on resale.

Would you trust a set of RBs/STG2s that had been on a car for 15K miles? I wouldn't.

Its more about the PR and WGDC than WHP that implicates how hard turbos are pushed. 520Whp is very mild tune with well flowing inlets. Brian has dynoed 640 WHP with RBs which is pushing it. 520 WHP with his TFT inlets is far from "pushing it".

Chances are 2nd hand turbos are not good to be installed without full maintenance though. The good news is that you can do the maintenance for RBs with parts commonly available.

Absolutely, I was just relaying those measurements in a manner that would be digestible to a more casual reader. Backpressure ratios and duty cycle clearly aren't what the OP was interested in discussing. Though if you are genuinely concerned about backpressure, juiced up stock frames are not what you should be exploring.

I politely disagree that a 520WHP RB setup will last for a "long time", regardless of inlet choice. That's just my opinion mixed with prior experience. YMMV.

I see used RBs go anywhere from $1700-2200 (not rebuilt) to around 3k rebuilt, with with some options.

If you are looking to pick up a set of Rb or vtt, inlets IMO is a must as well, so factor that into the purchase price + install.

It's by no means a "cheap" undertaking to upgrade your turbos, but IMO it's well worth it if you plan on keeping the car for 3-4 years.

That being said, the market is changing so Quickly (single kits, stock frames + inlets, larger twins) who knows what pricing will be...

Your last statement is a great point. The market could be much different in a few years.

My debate is, do I eat the $600 and keep my stock turbos with the hopes of recouping $1,500 to $2,000 when I decide to part out my car.

or

Would I be better off to take the $600 now and then sell the car with the upgraded hybrids. If I decide to go this route, will either of these hybrids work with stock tuning?

You can find stock turbos for $300-$400 bucks all day....

Trade them in, and buy a set of used OEM turbos when u decide to sell.

RBs or Vtt would "work" with stock tuning, just not near their full potential. But I'd personally take em off the car and recoup some of the money.

Side note- having an Rb + inlet combo, I smile every time I hit the gas

Enjoying my car made the investment worth it. Cmon you are in finance, car stuff financially is suicide, but being an enthusiast, and enjoying your car makes it worth it

The money you'll receive back just have your car in stock form when you sell it would probably fill most of that void. So it would definitely be more beneficial to keep the stockers. I guess it depends what price you put on your time to do all the work.

On a side note, i dont think the OP is trying to go out and set HP records, he's very realistic in his goals. I think a pair of RB's and some inlets would be a great addition to the Z4. It would be one hell of a fun good-all-round car.

True. If I could not afford it then I would not own a BMW. lol At the end of the day this is a hobby to most of us but I am always thinking ahead and trying to save a $ if I can. I am pretty sure that I am going to go with RB's and some inlet setup, probably VTT but I am not sure. The Z4 has much more room in the front and rear of the engine so I could use piping that is much larger than what is available but I don't want to try to put together a kit myself. I have access to a lift in my garage so I will do the turbo install myself and my labor is free.

If you are a financial advisor, I suggest you do as I do and treat all mod money (and even the car itself) as sunk cost. When I sell my cars, I part the mods out and get what I can treating that money as a bonus (I assume they have no value). Otherwise, you'll stress about the depreciating vehicle with super depreciating modifications. His is why I don't care about how many miles I put on my car.

Hell, many of us used to pay $900 for down pipes, lol ($300 shipped now).

Totally agree. It's not an investment, it's a sunk cost towards a consumable good. Treating as anything else will just lead to stress.

Ah yes, the $900 downpipe days....Do you remember the $1,300 Akra DPs? That was

What is the whp potential for RB's or VTT Stage 2 with inlets on 93? I am most interested in getting a setup that can give me 500 to 550 at the wheels without using E85 or Meth. What are my best options?

no meth and no e85 is going to be pushing the turbos to the max if you want to get to 500/550 whp.

As far as resale, like the ghost said, treat it like sunk cost and then bonus cash if you sell them. Its the less stressful way of modding.

I would say you would be around high 400's on 93, maybe 480ish, just a guess though.
