1.6 cy TD bottom end 1.9 aaz head project

[Rabbit on Roids]

hey kev, stick to our side of the board... the IDI section. you wont get much help in the direct injection side of the board. TDI specifies Turbo Direct Injected. IDI specifies In-Direct Injection. when we say TD, we are talking about turbo idi engines.

OK, so noooow I understand a little better just have to move the ol thread, got it.  I am using a Turbo 1.6 block I know I'll need different pistons because the block is bored and still has visible cross hatching.  I also dont want my pistons "under turbo pressures" to melt or explode "let's just say it would be a bad day" I REALLY! want to do this I don't have a good junkyard or a machine shop anywhere nearby out here in the desert.  This coumpounds my problems, also, thanks everyone for your VERY! valuable input you can't really put a price on this stuff.  Just goes to show ya, I'm still learning and am not to high on the hog to come down and admit that I don't know everything.

Thanks,

Kevin

P.S. adversely how exactly can I "MOVE" a thread? moderator anyone?

In case the PM was not recieved, Thanks Vince, "the moderator".

so there is no such thing as a tdi aaz? I have seen them elsewhere too on the vortex.

thats an AAZ TD head. still indirect injected. turbo does not specify TDI.

yes, i keep trying to tell him that. he keeps trying to get all these parts and stuff before he even knows what he needs. just chill out for a while kev. get things sorted out and find all the parts. theres alot of parts that are gonna be pretty hard for you to find.

sorry guys I am just soo stoked about this build, I went up to Sac CA and just got back "check the date stamp" anywho I bought a 1.6 TD block crank and pistons from another member who posted on craigslist for $200.00 THAT I know I'll need regardless 1.5 block cracks easily, got it. Research first, I tend to jup rather head long into these thing not so much a leap before looking sort of thing I am just getting laid that often

you are probably going to need a 1.6 head too. and everything else on a TD motor that is specific. you are a lot of parts away from a finished engine.

[thedeezel]

You can do a 1.6l td bottom end, with a 1.9l AAZ head. It is an IDI engine, as the fuel is not injected directly into the combustion chamber, also the IDI head has a pre-combeustion chamber built in, whereas the TDI has it in the piston itself.
I am building the exact same engine, 1.6TD block and rotating assembly with a 1.9l AAZ head. You will have to modify the head a little for it to work properly, but these mods are fairly simple. You will also have to make sure you measure for the proper head gasket to ease with starting, even though the cold starts will be litle more difficult than a normal 1.6td.
The major benefit of this combo is the ability to run more boost, due to the lower static compression with the larger cc volume in the head.

this I understand, but i still need a 1.9 aaz head I'll use my 1.5 head "12mm holes drilled in" on the 1.6 td block for now N/A "higher static comp." just to get up and going I need a stronger fuel pump, new pistons, injectors, turbo, intercooler, piping, metal head gasket, ARP studs,oil pump, water pump, "the block is bare so I need a lot"  I also need all new well basically everything fuel lines, belt, dipstick, and the list goes on, Wohever said it was right hat I need is a complete 1.6 TD engine, just don't have the money now, will have to wait.  I am going to get a re-ring kit for now and head studs and gaskets, to build this to drive for the time being.

Thanks,

Kevin

i told you that you should have waited a little longer. you dont have near the pieces you need huh? its barely gonna work. i wouldnt ruin that 1.5 head if i were you. just get a n/a 1.6 head. this is turning into something band-aided together i would expect from a tweeker. something like the guy that bought the 1.8 16v gasser with a AAZ head on it. that motor was most likely built by a tweeker. why dont you wait and just do it right? i told you that it was pretty much pointless buying just a turbo block by its self. you need EVERYTHING ELSE besides the block. you can get away with a stock 1.6 block if you want. if you dont have piston coolers, just run enough air to keep things cool. thats why i like my VNT so much. plenty of air. trust me dude, i tried to do projects like you. "try and finish them before you even have enough parts to start". well, im here to tell ya that it works so much nicer when you wait to do something till you have all the right pieces to build it and install it.

^^^^  X2   If you don;t have the money for a 1.6 TD now, why not save what you'll be spending on a mess and put that towards doing the job right??   Buying alot of random parts that won;t work well together isn't going to be of much help...

   A starting point could be if your 1.5 head is good, sell it!  THere are those who are looking for those from time to time...

[theman53]

would the precups from a 1.5 fit in a 1.9 head to get about right for a 1.6 bottom???

[rabbitman]

1.5 pre-chambers are proportionately smaller than 1.6 pre-chambers in order to achieve the same compression ratio.

Actually my bentley says the 1.5 is 23.5:1 while the 1.6 is 23:1

Does anyone have any 1.6 and 1.9 precups. to measure if they can be swaped?
