The mk3 1.9L TD power-quest

Aren't Kart engines 2 stroke engines ? (ie very, very different to 4 cycle diesels with compression ignition, valves and turbochargers)

I seem to remember burning holes in a piston or two from running 2 stroke motorcycle engines too lean for too long at sustained high revs (but I agree, more torque and power on the lean side rather than rich).

Yes they are 2 strokes, but you are still compressing and burning a charge the same as everything else. It was mainly a comparison, i'm not saying 2 stroke tuning directly relates to diesels..

Ideally, with a 2 stroke, you want the faintest sign of detonation pitting juuuust around the edge of the piston and combustion chamber. BUT, you have to get that without the engine getting too hot. Very tricky, and i'm not going to say much more. Wrong thread, wrong time, and it takes a lot of time and money to learn such things.

so ,some porn for you diesel heads....

i hope you all know what this is started to clean it up today


to give you an idea of sizing

left, k14 compressor housing, right k04 compressor housing

EGT probe mounted in the old EGR blanking plate

oil catch can i made up at work the other night. i ended up going with mild steel (it was handy) and painted black... not sure about the location yet, hence the cable ties

bad picture of the installed guages in the centre console.... from left to right - oil pressure, EGT and boost

another bad pic of the guages when ignition OFF

new 'cooler piping...

where the "magic" happens


and a little off topic - my front yard a couple of weeks ago:


my sisters GLD - used to be GLS, converted and painted by my dear old Dad

Everything is looking good!

That's mine.. Oh wait...

[gldgti]

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

use every good engineers favourite tools,

WD-40 and a hammer

Hahaha nah only 9. And only when i need to!

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.
