Frankenturbo F23 K04 hybrid swap

[jesse500]

So Im thinking of doing a little power upgrade on my 04 USP, car has 125K on it. I can get a F23L, k04 hybrid for a good price (genuine BW turbo). I have 410cc RS6 OEM injectors right now. Could those injectors push enough fuel for that turbo? Even with a conservative tune? Will my stock exhaust & intake manifolds work for that turbo?

I have 3" TP, stock downpipe, soon to have stock exhaust with mufflers & no resonators. already have a Forge DV valve.

Stock intercooler right now. It is about 20 below celsius here, and will be below 0 for the next 2 months. I dont race my car, just spirited street driving. Do I have to worry about intercool atall, or at least when summer comes, for heat soak issues?

What all would I need? the turbo, TIP?

is my stock MAF large enough? Or do I need a 3" MAF?

will a stock clutch handle that power level? Stock clutch, almost brand new (12K on it).

any difference in plugs to run over my BKR7E's?

the answers to all your questions are the same ones that apply to the F21, so just read that thread.

Cannot find mention of the answers I am looking for in any thread. Just what people installed, and how much they liked it.

Go to Frankenturbos website. See what they suggest in their kits.

First off, the F23 is for transversely mounted 1.8ts found in VWs and the audi TT. Not the longitudinally mounted audis. We get the F21L. So get your shit straight, a F23 wont fit without some serious serious modifications which make it pointless when you can get a F21.

1) You will need a 3" Maf housing - just pop ur current maf sensor out of your old MAF housing and put it in the new 3"
2) The injectors you have could work but you will need a custom tune. You may be better off selling those and getting the correct injectors for the turbo and an off the shelf tune
3) Frankenturbos come with a TIP
4) Your intercooler will probably heatsoak rather quickly
5) Stock clutch should be okay but it will probably wear out at an excelerated pace. ECS makes a few good "RA4" clutch kits that will hold your new found power.
6) Use the FUCKING search function. This shit has been gone over over and over and over and over again. Its like beating a dead horse.

Take it easy on the guy, he's only been here since November. This stuff may have been covered numerous times but the search function isn't always friendly. A quick link for the guy would have been a huge help.

FrankenTurbo customer service sucks, go with them if you potentially want to be left out to dry if you ever needed him. I sent him dyno sheets and my data logs off my k04 setup and the only gratitude I received was ignored phone calls. Buy a borg warner k04 you will not be unsatisfied.

cranky.

I did search, and I didn't find the advice I was looking for. And I did not know the 23 was for transverse, just thought it was the Frankenturbo version of K04.

And if everyone with any question, only ever used the search function, they wouldn't be too many new posts on the forum. Thats what leads to slow, or dying forums. New posts, keep the forum constantly busy. Which is good! So Dont be too quick to tell people to search everything.

I may end up trying to find a stock K04. Would be enough power for me, and better suited to my clutch. Just found new F23's locally for $600

[PreciseD]

Stay away from the Chinese junk turbos. Just go with a K-04 and call it a day.

I was as fast as a stock full exhaust 04 gto 5.7L LS1. I made 256/ 293. The car scooted nicely.

Are the Frankenturbo's Chinese made?

[DiertyEuroSpec]

I told you a Borg Warner K04 is the only way to go if you want to have a hassle free reliable turbo now buy mine already!!! LOL

[jesse500]

These were OEM bog werner turbos, with the upgraded internals. And was a local sale.

If the exchange rate was not 1.4516 right now, I would have.

How much are you asking / how many miles are on it?

FT and OEM doesn't sound right to me.

Borg Warner's are made in China..... FYI

[DiertyEuroSpec]

And your point is? Its a Borg Warner which I have for sale, and is from the turbo manufacturer which outfitted our cars from the factory. That said our A4's consistently run 150k miles on these turbos and keep on ticking. What was your point about the orgin of them exactly?

Also wondering where you obtained this information? A link for me/us to read would be interesting.

BW has a a Production facility in China, for the Chinese market. Still facilities here to make us real 'merican turbos

Frankenturbo does not use BW turbos, unless you are now talking about a different turbo? It also sounds like they have S4 turbos if there are two of them and they are not compatible with our 1.8t.

As for the China thing didn't know our K03's were made in China haha go figure. Also the fact they are made in China really doesn't mean anything. It's the factory they come out of and the quality controls the factory is using. China is notorious for their cheap copied crap because that is what they are good at and can make money off of. If someone is willing to run a factory and pay for quality manufacturing it makes no different if it is in China or US especially because of something called ISO9000. They follow rules that are set across the board.

You will not be disappointed with the FrankenTurbo.
I've been running mine for a few years, and it's amazing. went with the Motoza tune, upgraded intercooler, etc, etc
I do have the stock throttle body and MAF


the original stock clutch held up fine for a few years and about 50k but finally replaced it with a performance one, even though the stock one would have held on a while longer

This is exactly right. They did this so they didn't knock off the turbos. It was a smart move by BW. This is the same move that Audi did. They have a Plant in China and build Audi for the Chinese market only.

When I was over there I saw so many BMW X5s and Lexus Rxs. Come to find out they are knock off cars. This is what Audi didn't want to happen.

Now they do this

Yes, however, genuine BW turbos are not counterfeit junk sold at ridiculously low prices. I am amazed how many counterfeit K-04s there are on eBay selling for less than $300.

Theoretically, eBay policy prohibits counterfeit items. eBay does a lousy job reviewing and enforcing listings for policy violations. The poor enforcement of policy associated with the flood of counterfeit merchandise damages eBay's reputation. eBay is close to being universally known as eBay = counterfeit junk, especially in some categories more than others.
