Hey Guys, I'm in need of a preferably used K04-15, Frankenturbo or GPOP K03/K04 Hybrid. My turbo is very much on it's way out, and I'd rather upgrade now then spend more money later. Trying to see if anyone has a used one that they need out their garage before I buy a new one. Shipping to...

So I am preparing to purchase the F21L kit for my 1999 AEB Passat. I'm currently looking for a tune and would like to get your input! The tune I'm currently looking at is the Stage 3 tune from United Motorsport for the B5 A4 found here. Do you think the 630cc injectors are overkill for this...

Hey guys! My stock turbo just bit the dust, so i'm looking to go with a frankenturbo. The car is a 2003 B5.5 Passat AWM FWD automatic. I'm going with the F21L kit w/ the C2 Motorsports tune w/ 440cc injectors and 3" MAF. I already have an upgraded DV so no need to worry about that. I have been...

Just wondering if anyone has a good clutch laying around with plenty of meat left on it that they're ready to part with. Lemme know please!

Living down under in Australia and with an older style ECU I have as some of you already know, found it difficult to get a tune for my B5 Frankenturbo install. I gave up on local and UK tuners - complete waste of time - and most US tuners were not interested either tuning for an older style ECU...

My stock turbo on my GTI is dying, so I have some spare parts laying around I'm trying to get rid of to fund my next project :) OEM FSI HPFP (120K) - 85$ High Mileage, but not a thing wrong with it. I changed my cam follower every 35k-40k, and there aren't any signs of wear on the internals...

This is all stuff coming off my car because I'm upgrading to a GT2871r setup. Shipping is not included. Shipping will be whatever shipping costs. SOLD: genuine Borg Warner K04-15 from 034 Motorsports. SOLD: Cast, high flow exhaust manifold for longitudinal 1.8t engine with K03, K04 or Hybrid...

If been researching a ton on upgrading to a frankenturbo but keep worrying. I ask people with this Turbo. Did you have to replace your center cart? I know slappy offers them for 150 which is awesome but it seems like most threads I read say something about tTurbo needing to be replaced. I...

Spoke with guys over at um. I think I'm gunna go with their tune. They have a 440 file that produces 250 whp and a 630 file that produces 290 whp. They said either tune would work nicely. He favors the 630. What would you run? Both tunes require stock fpr. Price difference of tune is...

So I hit up k0mpressed and he said he has a file for aeb frankenturbo...anyone ever run this tune?

2000 1.8t 5speed 140,xxx Okay so I haven't been active here in a while since I've been building my race car but I've finally found time to give the passat some love. I've decided I'm going to go with a frankenturbo and I have all of the supporting mods I need (exhaust, fmic, clutch etc) the...

So first I have a 2000 passat 1.8t atw with the wideband conversion with a frankenturbo f21. At first I had a tune made for my car and I was able to hit full boost (26 psi) by 3200-3300 rpm. Now I switched tunes since the last tuner disappeared and wouldent respond to pm's and had some issues...

Hey whats up everyone? It's been awhile!! I have a Frankenturbo installed 2.5" CIA with a k&n filter, catch can, all the other supporting mods. So my valve cover is constantly leaking at the rear of the VC on the exhaust side, Ive replaced VCG several times with OEM gaskets and black RVT in...

My cheap china turbos wastegate blew off... I'm looking for a replacement that will last longer then 40k.. my turbo only lasted 10k miles , I currently have the pc16 upgrade kit with all the needed mods. Main question how long do the franken turbos last? And how long can the borg warner k04...

Ive been searching for a while but I'm looking for some newer/current feedback. Has anyone been running a frankenturbo or gpop without much effort? I am not a mechanic and cannot troubleshoot myself. I need a Turbo for my aeb that will be as turnkey reliable as it is now. I read that k04...

I am selling a hardly used Frankenturbo F4H-L Center Housing Rotational Assembly (CHRA), for use in Frankenturbo 1.8T Longitudinal applications. For those who may not know, this is the internal guts of the turbo, shaft, bearings, wheels, all in one piece. The CHRA is straight out of the...

I am starting this thread to publish a conversation and invite others to weigh in if able. With tools and code blocks for tuning our B5 and B5.5 ECUs becoming more and more accessible every day to the tinkerer and tuner alike, I think this forum needs a few conversations or perhaps a whole...

At the beginning of 2012 this was pretty much a stock K03 setup albeit with an Austrian Stage 1 chip I bought off eBay for about $120 and installed by soldering a socket adapter in place of the stock EPROM. Yes I can hear the jeering condemnation and assertions that a chip off eBay couldn't be...
