The mk3 1.9L TD power-quest

That's mine.. Oh wait...

if only i can get mine to go as fast as yours will

i'll need twice the torque of your 16V for the first 5000rpm... since you will be revving out to 10!

well, finally replaced clutch/pressure plate assy on saturday.

friction disk seemed ok - not too worn - but clearly contaminated with oil. shock springs stuffed as usual (180,000km). inspection of rear main seal yeilded it to be fine. im sure oil got in to the bell-housing from an oil pressure sender leak.

cleaned up the gearbox/flywheel. new pressure plate on with new bolts and new friction disk.

chucked the old original "self adjusting" crap heap of a clutch cable for brand new manually adjustable unit. woot!

i now have POWER TRANSMISSION to the ROAD!

i cant believe what a difference it is... i can actually get the benefit of my 20 odd pounds of boost now!

pulls like a freight train from 1800-3700. its still a diesel. its still not fast... but it is definately getting faster

having trouble pulling the T3 apart for rebuild..... its all siezed up. i'll get there

ZEP 400 craps all over WD40 if you can get it.. My old man never goes without a can!

Good to see you finally got the clutch done.. It needed it.

where does he get it?

sure did - abysmal before really!

btw - also put in some urethane eccentric rear wishbone bushings to correct that castor issue i had - coupled with some new rubber and yet another wheel alignment (pedders in hornsby look after me now the car finally drives DEAD STRAIGHT!

pedders actually took the time to think about it and set camber to 2.5deg neg on both front wheels with a little toe in just like i asked, and finally i'm happy with the results. plenty of grip and turn in, not too extreme for the highway. looks smart too with some decent neg on both front wheels

oooohhhhh! wheres my camera....

I'll find out for you when he gets back from the US..

about to get banned...

just played around with my "springs and levers" a bit more this morning... hello horsies

mananged to change the on boost fuel adjustment spring to a stiffer one, so that as boost comes on, fuel delivery is a little LESS - so i can set the peak delivery HIGHER than before, i now get less smoke as boost comes on, but more fuel when boost gets above 12psi - so less smoke, more power! also means i could wind the max fuel screw in a bit more to get a little better top end.

Very nice. I take it that it has given the engine a more progressive fuel delivery, and therefore a better burn right through the rev range?

Top end in a diesel?? Hehehe sorry had to say it.

thats right - basically the fuel delivery more closely matches the air delivery now. top end? whats that?

cant wait to get the little tiny k14 off it and stick the t3 on - then we'll talk about top end. kurrent turbo is SOOO restrictive.

at the moment, i have the smallest turbo i posess on the largest, heaviest breathing engine i posess.... not the best combo.

more boost

well, after noticing that over the past week the peak boost that i've been hitting has been gradually decreasing (down to 15psi :-o !!! ) i was convincing myself that this was it - turbo going west.

but, nay! saturday allowed me to take a look under the bonnet and not able to see anyhting much interesting, i decided maybe i needed to turn up the fuel a bit...

after a drive, where-upon i was only able to hit 18psi once, i was back to being dissappointed....

to try to bring back some of my nerve i tried a 0-100 time to see just how the car was feeling when giving it heaps - ended up at 9 seconds to 100km/h and egt peaked at only about 550C.

got home, had another look around, and then noticed that revving at idle made little puffs of smoke in he engine bay.... then i found the culprit - leaky plate where i'd mounted my EGT probe in the exhaust manifold!

decided to go all out today, and made from scratch a whole new blanking plate for the egt probe out of some nice 5mm plate.... bolted it up and went for a run.... WHOOSH!

now i have a peak boost around 22-23psi, and notably quicker right across the rev range on boost - wooo!

feeling pleased, i spent the last 4 hours cleaning her up

[Preen59]

Congrats on the progress! Hurry up and bash that bigger turrrrbo on it!

[Jarred]

Bloody looks tops I reckon. love the colour, and it's so clean! (not a fan of the head lights though..)

Best of all DIESEL POWER! Good stuff.

I would have looked at buying that one in (QLD?) that was for sale, except, I already have 3 cars. bugger.

keep up the good stuff.
