1.6 vs 1.9

[carrizog60]

i am going to convert a 1.6D to TD.
will have i.c. and oil cooler to pull the temp a bit down.
is the 1.6D head the same as the gtd?
as soon the car works i will give some news

Would the 1.9TD bolt up to say a 1.6D tranny, and what would the deal be on the engine mounts :?:

I'd go with the 1.6 if I were you since the 1.9 is notorious for crankshaft sprocket keyway failure.  An extra .3 litres of displacement will hardly make a difference in power.

Since I have the same turbo and boostenrichment on my 1.9 as the 1.6 has (KKK K24) I can say that every comparable tuned 1.6 eats my dust 300cc of displacement is a LOT, almost 19%! The faulty crancksprocket is easy to spot (flat bolt head instead of a small bulge) and changed in 15 minutes when the engine is out of the car.

The 1.9 bolts up to any 020, 02A or 02J tranny except the V5/V6 trannys, just like any other VW 4 cyl does.

For the distributionside you need the mount from a mk1 gasser, the holes are already in the engineblock, the others just bolt on from your old engine.

The crankshaft sprocket on the 1.9 can still come loose with the new style bolt.  If the sprocket does come loose, it will do damage to the crankshaft.  If it comes right off, valves will hit pistons.

If torqued to spec with the OEM bolt? Then you could say that every engine with the same design has that fault...  :?

Thanks for the heads-up on the crankshaft bolt. I heard of it before and was intending on doing the mod mentioned on vwquebec.ca.
A couple guys there solved that problem. I'll have the engine out of the car anyhow and can do somewhat of a rebuild.
Actually am now leaning on the 1.9TD as donor motor of choice over the 1.6TD. I want to do it right the first time :wink:
Thanks,
Hugh

Yes. My 1.6D tranny also bolted right up to a 1.9 TDI from a 2000 Jetta. Yes I know that's recipe for destruction (for the tranny).

Yep

ok,so i am going with the 1.6D engine and tranny,so what power can i squeeze reliabily?
the only problem could be overheating?or should i look for others^?

reliably? you are adding a turbo to an engine that was never intended to have one, keep that in mind.

first thing i would do is get it setup and running smoothly with the boost turned way down. get an EGT probe hooked up. drive it like that for a while and get a feel for it, work out any issues that may come up. once you are confident with the motor, i'd start turning things up... but keep a close eye on EGT numbers when you are in the boost. the IC will help.

if it were my car i'd just find an MF code 1.6L TD from a jetta and swap it all over. have fun  

[Maarten]

I suggest you sell the 1.6D and buy a TD engine.. the 1.6D does not have oilsquirters to cool the pistons. Look what happens when a squirter fails:

my mechanic said that i can run boost as a normal engine(gtd) and no problem if tuned up well.

one of it s last creations is a renault clio 1.9d that become 1.9 TD.
1.2 bar and still running fine with no overheating... :?

[larry104]

Is parts availability a problem for 1.9 L TDs in the U.S.? Do parts cost alot more than for a 1.6 L TD? Is the difference in power between a  1.6 TD and 1.9 TD that noticable to justify a swap?

[Maarten]

Overheating is not the problem.. heat management in the engine is different between the 1.6D and TD. I can't say anything about the renault, could be that those are the same engines apart from the turbo.

But I wish you good luck with the mod

[BlackTieTD]

i want to reply without sounding like i'm starting a pissing match...

just be careful and don't be foolish with your money. 1.6L TDs are not that expensive. by the time you go through the work to make your own TD from a naturally aspirated diesel, you certainly wont be any further ahead than just starting with a 1.6L TD in the first place... and thats best case scenario.

if it is for the learning value, do it! (but it sounds like you are going to have a mechanic do the work). i'd like to try to turbo a NA diesel, and blow the motor sky-high when i pushed it too far, just for the experience (and so i'd have pictures to show you why not to do this  :lol: ). but for a daily driver, i'd swap in proven 1.6L TDs from mkIIs all day long before i'd tackle the D>TD project.

either way, good luck.
