mk2 or mk3 unsure which to use...

[bobmaf]

i have a mk2 1.6 gtd and i have a mk3 1.9td (aaz engine)
which would better the mk2 with the aaz engine installed into it
or leave the mk3 and tweak that ?

[burn_your_money]

They are both good engines but with pretty different characteristics. What are your goals for the car?

[bobmaf]

well either way they are better than petrol in costs/mpg so mpg isnt an issue
but yeh i`m after top end speed and set off speed

my mk2 1.6gtd tuned is quick but not quick enough

[LoneWolf]

mk2 with the mk3 engine, but use the mk2 turbo setup, thats what im running, its pretty economical and a good bit of fun to drive

[bobmaf]

i spotted something about upgrading the injectors do u know anything about that ??

[LoneWolf]

TBH im not too well clued up on injector swapping, but ive been lead to believe that for mild tuning the AAZ (mk3) injectors are good to go

[bobmaf]

well i collect my aaz mk3 next week so al see how she drives still in the mk3 body first and then see if she wants an older shell to ride in 
cheers

you will love the torque of the 1.9.  the only thing i would recommend is a taller transmission as the 1.9 doesn't like to rev like the 1.6.

[bobmaf]

which transmission would be best ?

[rallydiesel]

Or put the 1.9 head on the GTD. If you go with the AAZ in the mk2, use the GTD pump and take the camplate out of the AAZ pump and put it in the 1.6 pump. The 1.6 pump has more adjustability than the AAZ pump. Don't bother messing with the nozzles, the GTD pump with the 1.9 camplate will put out more than enough fuel.

[bobmaf]

ok well i wont be doing anything just yet as i`m going to get the mk2 body all repaired and resprayed before i do any changes to the engine
cheers

[LoneWolf]

You got any pics then Bob m'laddo?

[bobmaf]

i use a freinds tinterweb so i dont have any pics
ive got loads on my phone lol

well i got my mk3 (aaz) yesterday and she drives quite nice i`m suprised but i am still going to drop the aaz into my mk2 and shuv the gtd into my mk3 and use it for a while until i get everything sorted on the mk2  ... aaz requires a clutch desperatly and i aint sure if the 1.6 clutch will fit the 1.9

1.9 head on the GTD gets my vote!!!

well ive changed the boost pin i swapped it with the one out of my gtd and it made a hell of a difference ive turned the fuel up, blocked the wastegate/dumpvalve thing and its lovely now
next job is to do the gov mod and install the intercooler....... wow its going to be lovely when i put the engine into my mk2
