1.9 tdi ASV 81 kw

[1M Tuner]

Hello everyone from Croatia, I have one question for you tuners, I bought the first car for the project Seat Leon 2004 1.9 tdi ASV 81 Kw, for the beginning my goal is to raise the engine power to about 200 hp and insert a 6-speed gearbox, what I need from parts to get 200 hp and would the engine last that long, otherwise the engine is in very good condition and runs like new

Engine will be fine at those sort of power levels.

You will need larger injectors, like .240/.260 nozzles, stock 10mm pump is OK for this application.
For cheap turbo, you can take one from a PD150 ARL, GT1749VB. It will see 200hp. Better option is a GT1752 hybrid or a larger turbo (GTB/GTD series) but these do not come OEM on these vehicles.

Of course normal modifications like exhaust, downpipe, intercooler, clutch will also be required!

would a 6-speed gearbox from a Golf tdi 96 kw fit?

Yes, take gearbox, driveshaft, clutch pipe, flywheel, clutch, starter motor, shifter bracket and ends.

All direct fitment as long as you have all parts

I know that I'm late to the "party" but if you haven't gotten the upgrades done yet, here are the parts you need to reach 200hp.

The PD Injectors that'll easily get you to 200hp and beyond if you wanna push it a little bit beyond that.

The turbo I'd recommend is a GTD1752VRK.

Then you'll probably wanna upgrade to a better clutch, like this one.

Hopefully some of that info will help you out.
