tdi upgrades i need help with

[80andyb]

hi guy and gals.iv just bought my very first audi it's a 93 audi 80 1.9 tdi and im after some info on upgrades.i know this is old news but iv been looking for the past 2 days on google and the info seems to be all over the place and its realy starting to hurt my head lol.
so far iv orded some 40mm springs,decat the exhaust,blanked the egr valve,cut the small plastic pipe out and drilled holes in the air box,

right my question are:-
what cars and years can i get the bigger injectors out off ???(110 hp)or can i go bigger

can i up the boost on the turbo without getting it chipped(boost valve control)???if not what would be better chip or a tunning box (seen some on fleabay)

any help would be great

cheers andy

Hi,

Bigger Nozzles are: Fratelli Bosio RACE520, or DSS Ultimate, or Power Plus Race ...etc.. all have 0.260mm.

Turbo: Can you put Garrett GT1852V, GT2052V, GT2256V, GT1756VK...etcc...

I recomend Big FMIC.

Good clutch to more that 450Nm, Map sensor of 300kPa, with head of 11mm..

And some parts

Example of my costumer that i remap..

thanks guys for your replys iv got a spare standard head in the shed as you do lol so ill have a look at getting it ported.i want to replace the head gasket anyway if im going to start uping the power

i will recomend to change the conrods, before the engine goes "bananas".......

[80andyb]

is that a weak point on these engines???

[caterpillar]

all audi vw have weak conrods, how mutch effekt you want?? the tdi forum does have 230hp 1,9tdi's.. and i have seen a audi a3 with 430hp with 2,0 PD engine

[80andyb]

id be happy if i could get upto 150hp but then i can never stop messing about.230hp sounds amazing, i only bought the car to pull a car trailer so i can take me m3 evo to track days etc.......its turning into alittle more than that now though lol

always the way
