VW TD HYBRID 1.6 HEAD & 1.9 bLOCK??

[Tiago PSS]

hI PEOPLE, im from portugal and i have a 1.6 td vw mk2 and i want to know if a hibrid engine(1.6 head and 1.9 block) with a PD130  air intake and exauhst intake from an PD or a GTTDI with a vnt20 turbo and mercedes injectors with a 1.6td fuel pump and a 1.9td transmisson work's good?
that's my question! Hep please.

Hi, unfortunately, your compression ratio will be way too high with that combination.  The reason is because the the swirl chambers on the 1.6 head aren't big enough to handle a 1.9's worth of displacement squished into them.  Even using a thicker head gasket to compensate (which generally isn't considered a good idea on an IDI engine) won't be able to bring it in line.

1.9 head on a 1.6 works great, but a 1.6 head on a 1.9 is just pointless, i bet the engine would lose power.
the 1.9 head flows way better than a 1.6 head. and lowers the compression so we can build more boost.

hummm..but with a gasket more thicker i will able to lower de compression ratio...and the 1.6 i will increase the air flow and put bigger valves. Lose power i dont think so ,the risks
 ,is the engine crash, like in every modification is. I know a guy has done well and resulted.

The 1.9 head has bigger valves then the 1.6.

Putting a thicker head gasket in won't significantly reduce the compression ratio, but it will certainly screw up squish, quench, and the turbulence in the swirl chambers.

Good luck with your project

hillfolk has a mk2 coupe with a 1.9 block and 1.6 head he said it runs good, i think it's just na.  either way theres no way it runs as good as a regular 1.9 considering the valves and ports.

yea, not a chance in hell it will do as good w/ a 1.6 head. the valves are bigger, the ports are bigger, and i think the cam may even have more lift than a 1.6 cam. sure it will work, but why would you want to make it harder for your engine to breathe? that just sounds stupid. and you will probably have like 30:1 compression. thicker/more head gaskets work on gas engines, but they arent as critical on the squish, quench and turbulence in the combustion chamber.

tHanks for your opinion, im gonna think and shearch more about it...With a hybrid engine how many hp you can get in a vw mk2 with a block 1.6 and 1.9 head.

1.9 head on 1.6 will do as much as the rest of the mods will support. The head allows better breathing, so you can do more with fuel, intake, boost, exhaust, etc. than what you could have before. This is all to a point, I don't think anyone has made over 300HP with one of the 1.6s. I know I have heard of some that were in the 250 range.

[Tiago PSS]

250Hp?? I can belive it! can you show me some videos??? the 1.9 head stock and 1.6 block stock?
tell me what i have to do to the head an to the block to reach at least 220hp!
I want to put an VNT turbo to i´m tinking about vnt22 help me to put power in my mk2 ,was the first mk2 turbo diesel in portugal to reah that power!!! it´s insane man!! Please teach me!

[burn_your_money]

Just read the FAQ, search the archives and read the build threads. You'll find the info you are after

[Rabbit on Roids]

220 horsepower is going to be hard, well, rather, expensive to build.

[Tiago PSS]

expensive ?? tell me more about it

ve o mjf e os tipos dos paises nordicos...é de la que vêm os motores mais potentes.
o meu tinha quase 140 e só tinha debito e pressao de turbo,além de ic e afinaçoes na bomba....


sorry for the strange language text for the rest of the guys
