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.
-
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!
-
Just read the FAQ, search the archives and read the build threads. You'll find the info you are after :)
-
220 horsepower is going to be hard, well, rather, expensive to build.
-
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 ;D
-
you pretty much need a giles pump for 220 horses. or be able to build a giles pump by yourself. and you need a nice big turbo. im pretty sure no stock turbo would be happy singin along at 220 horsepower. you NEED head studs and a metal head gasket. and you gotta get a good intake that will flow plenty of air. and port the head. build a big exhaust. you know what, im gonna stop here...
go look in the FAQ section, theres topics how to build power. they tell you everything you need to know, and alot better than i can.
-
Yes i know that but in the FAQ dont talk about hibrid engines...I just want to know if the block stays stock and the head too...the rest i know a little about it...
-
stud the block. if you use main studs and head studs with some good ARP rod bolts, it should be good to go for any horsepower.
do a search for 1.6/1.9 hybrid. there are pages on here detailing a build of one. i know for a fact, ive read about it. just remember to plug the spare oil drain in the front of the head.
-
thanks rabbit!!what is the turbo that you advise for 220hp? vnt22? i´m think im gonna put the gt2052v of the 2.5 tdi audi.its a good choice???
-
i think it would work great. i just have a VNT 17 on my car and i love it. spools up like a tiny turbo, but boost like a big turbo.
-
for more than 200hp the vnt20 would be too small.
i would put one on my passat but not trying to reach tha kind of hp...
i thing mjf had one and remember he said that would top out at 180hp, give or take
-
i thought he was closer to 250, but he has a 1.7
-
humm...so what turbo can reach the +200hp???vnt22?
-
i thought he was closer to 250, but he has a 1.7
thats now,i think.
on the begining he used a vnt20
-
a 22 would probably be closer. how big is your wallet? or your brain? you are going to need a huge one of those 2 things to make this thing have 250 horsepower. you either gotta have access to a machine shop and know how to use it, ir have a wallet big enough to pay the guys inside it to do the work. lol.
or you could always put an HX30 or HX35 on there, they would push out 250 horses worth of air no problem! and they are super cheap since everyone is taking them off there 12 valve cummins engines.
-
Yes i´ve have acess to an machine shop if the vnt22 it´s closer maybe the gt23 or gt25 are the best option.the hostel turbos here in portugal are hard to find. I´ve to modify the pistons to get more hp ??
please tell me more about it.
-
i thought he was closer to 250, but he has a 1.7
thats now,i think.
on the begining he used a vnt20
its dead now

dude, seriously, do some reading, the search function is your friend. people on here have done big horsepower builds on here, and detailed every aspect of them. andy2 has compounds, dyrtybyl or boostedblktruck was going to build a turbo/super charged engine. if you are gonna wait around for people to hold your hand, you may be waiting a while. now go get friendly with that search function. there are only like 400 pages of good information on this forum. how do you think all of us on here got so smart? real life experiences and reading posts on here from others.
-
Ok man! cool down i´m only asked for help if you are too smart to share it, to i´m done.
Thanks

im not being a dick, you are just asking un necessary questions. that are asked QUITE FREQUENTLY. so redrotors put a "frequently asked questions" section. its for the people who come in here and say "i want more power, how do i get more power out of my engine?" all the super common modifications are there. basically the necessary one. use the search function. read. dude, dont get butt hurt, the veterans on here told me the same damn thing when i first showed up on the board. you dont need someone to tell you something. you just have to find the bit of info you want on the website. like i said, theres almost 400 pages of GOOD MATERIAL in just the IDI section alone. build ups of EVERYTHING. turbo this, supercharged that, natural aspirated, anything you can think of. people have built it and talked about it.
and just so you know, i wasnt being mean to you. i was just telling you where you can find the answers. think of it, do you think we like typing the same thing over and over again? cause usually we get quite a few people every week that ask the same thing "how do i make more power?" you gotta look at it from my point of view too.
FAQ section and search function are your friends :)
sorry, my bad, theres only 328 pages of good useful material.
