I decide to upgrade my old Jetta 2.5 engine, but I found that a c2 turbocharger Kit stage 3 are much more expensive than change the engine by an audi tt 2.5tfsi one(used of course). Even if I include the intercooler and transmission its still cheaper than a turbo kit. Once the engines are very simillar, I think that I won't have many trouble doing that. Do you guys know what should I need to acomplish this engine replacement? I think I will need a stronger transmission because for what I know the jetta automatic transmission handles up to 250nm(some say 350nm) so I thought about the tt rs s-tronic automatic 7-speed transmission(600nm). I also know that the tt battery are on the trunk because of the extra room the turbo system needs, so I thought about doing the same with the jetta one or replace it for a slim profile lithium battery. What else do I need? Does the engine mounts fit the 2.5tfsi? Please I need some help.

if im hearing you right, you want to try and swap in the 2.5TFSI motor over tuboing your regular 2.5 motor? in the end i think the 2.5 with turbo kit will be cheaper bc of all the parts needed to swap to fsi, unless you already have a full donor 2.5 tfsi engine bay at your disposal, it's not just an easy swap. plus if youre not talking about swapping, the engine itself can b converted to standard injection but you'd need custom pistons, custom feuling, custom fuel rail, custom intake manifold, though you could probably get away with some components from the 2.5 standard injection engine, ur stil looking at a pretty tough job if you aren't good at fabrication or don't have deep pockets. I'm not gonna lie, this is almost every vw fan's dream engine, but it will cost you. It has really cool stuff in it that the regular 2.5 doesn't have, but if you really want the cheapest route, i'd say 2.5, port and polish the head, throw in some +1mm intake valves, forged rods and pistons, intake manifold turbo manifold etc you know, all the turbo goodies, but in the end you'll have an engine that will perform almost as good as the tfsi engine, you'lljust be losing out on a little extra power from direct injection and a little better timing as you won't have vvt on the regular 2.5... people have been making huge power witout both those options for a very long time, no biggie
The only guys really doing anything with the 2.5 motor are those swamping them into R32's and other various platforms. Trying to retrofit TT-RS components onto the regular motor is a complete waste of time. Better off starting from scratch.
thats what i was thinking, you could take a 2.0 tfsi engine and all its components to swap it into a mk3 and have a cool high performing engine. or for the cheaper cost, you could take a 20v head on top of a 2.0 block and have a pretty high performing engine and swap it into a mk3. the 2020 is going to be cheaper and pretty much just as good, but the tfsi into a mk3 does kind of give your car that extra cool factor or status. the 2.5tfsi is expensive, and for the next 10 to 15years will probably still be expensive. it comes in a $6x,xxx+ car that is pretty rare (never seen on in person), and then taking the price of everything else needed... its cool, when someone pulls it off well all be crazy excited andbow down, but if youre just trying to make power and have an effecient engine, there's no need for all that. look at it this way, a mk4 r32 has 241hp 237tq and a mk5 has 247hp and 237 tq, so a 6 hp and 0 tq gain is made from direct injection, is that worth every dollar youre going to spend on each little component to get it to work for that small of a gain? i think not. tech is cool, but not necessary. plus what if something blows? would you rather pay thousands of dollars for your really cool engine, or $500 for another 2.5 out of a rabbit or jetta?
By the time you make the adapter plate (you need to remove the top row of exhaust manifolds studs from the cylinder head) a downpipe that joins to the OEM exhaust system , oil & coolant lines AND you factor in the cost of a TTRS turbocharger you are DOUBLE what a C2 motorsport kit would cost.
OR...you could just do it to be cool.

"2.5 20V TFSI Turbolader - 07K145701B - Your price = $2344.19 USD"
That price is my price without shipping , duty or taxes.
Not doubting that you can make an affordable kit out of this but even used turbochargers still fetch a fair coin on ebay.de and other breakers around the globe.
Then you will need:
- Oil & Coolant line kit - $350
- Modified OEM oil pan w/10-AN oil return - 125
- Downpipe adapter to OEM 2.5 Rabbit exhaust system - $250-300
- Custom inlet kit - $300?$350?
- Adapter kit for FSI flange to 2.5 cylinder head - $200?$300?
I fail to see how this can be achieved for less than $3000 let alone less than $2000!?
If you can source TT-RS replacement turbochargers for under $2000 USD then sign me up as I would buy 5 today
A welded manifold like blue waters only costs about $100 to make, out the door. An intake, figure $50. Downpipe adapter would be $100ish. Charge piping would be about 100-150 for aluminum.
It'd be very easy to put together (manufacture) a kit for 1500-2000. But that's not retail. My time, at least, is worth more than manufacturing a kit at 1500 and selling at 2000.

After a long time of patience I have buy an TT-RS engine with LOBA LO500P Turbo, CNC Machine intake pipe and Fuel pump etc.
I will put this engine into my Seat Leon Supercopa and thougt that I didn't have work on this engine, but I whas disappoint when I take a look at the inlet valves
This engine have driven only 11K km and there is a'lot dirt on this inlet valves becouse there is no fuel anymore what will cool and clean his inlet valves.
I have chosen for rebuild this engine and I want 5 injectors extra for into the inlet manifold so I will have more fuel and it will clean and cool the inlet valves.
On this way I will pit in other (Lower compresion) pistons in it and other/stronger rods etc.
I think that this engine is not for the big power but it have an very wide powerband with a lot torque at low rpm what is perfect for my Supercopa wat is for race track and not for the 1/4 mile
The engine with all parts like wiring and ECU etc:
The stock and the Loba turbo (Stock is Left and the Loba is Right) :
The stock turbo intake is above and the CNC Machine is below:
The Carbon covers what can buy as option:
The part what we are making for an extra row injectors:

Not all parts will be in production because we can draw nice parts like you can also but you will know that sometimes the production is or to expensive or not possible with the machines etc.
When you can let me know what you mean, maybe I have still have the drawings ?
I am talking about the $1400+ USD belonging to INA Engineering Inc. that was paid for services / parts that we are still waiting for that you have asked us to keep private and off the forums under the assumption that you were given enough time to make it right.
If you want to advertise your products in this forum or on VWVortex then get an advertising account.Peddling for more work or showing off "cool" parts to entice new customers when you have old customers to take care of is frowned upon.
Do what is right.
