Any pics of where your air filter is located? Seen it just on the inner wing on Corsas, but batt's in the way on a Astra.
What IC is that?
Ive got a fooking massive IC(i.e. the size of the astra radiator), but think it might give problems with lag...
best place for the filter imo is up in the inner arch. boost pipes are easy to make, just buy a length of 2" exhaust pipe and make it from that.
the IC is off a focus i think
where could i find a n/a manifold had a look on ebay but none about? also where do you get the silicone hoses or are they just cut to fit??
Cut to fit basically, use any pipe/tubing to join some silicone pipes together....
NA manifold is off a 1.5NA diesel, corsa/nova
go to the scrappy to get the inlet. theres loads of them about
the N/A intake manifold it's a good choice.

"Mark the start position of the screw, then undo the lock nut (while hold the screw) now turn the screw 90degress (quarter of a turn) clockwise"
See, clockwise...
But just looked at the throttle linkage and turning it clockwise puts more thread out of the bracket, which restricts how far the linkage can travel on the pump.... So it seems a bit ermm, wrong???? Undoing it will let the linkage move further?
easiest way adam is turn it both ways and see which gives you more fuel. cant get a more deffinet answer than that
Hi guys, bought myself a 1.7 N/A Corsa Combo van a little while ago and even with the pump turned up a bit till it smokes like a chimney its epically slow :(
After a quick search on ebay I found a whole Astra3 1.7TD for sale, the guy was new to ebay (only 10 pos. feedback) and had listed the engine for sale with a whole car (to avoid the car listing fees). The listing was very breif and no one bidded so I won it for 99p!!!!
I stripped the car on saturday removing all engine components followed by the engine itself, but I have a few questions.
Q1: The engine is from a 1995 Astra which has an immobiliser. I removed the two parts of the loom (one seems to be for the starter/alternator, but it also goes into the cabin to a small black box and also a little yellow relay and the other seems to be just for things like temp sensor etc...). Considering the pumps are mechanical can I not just use the corsa's N/A loom??
Q2: The engine has been sitting for a few years and the turbo is seized (I suspect this is why the engine had been left), I am going to try an Isuzu Trooper turbo (I have found many people breaking the 3.1TD's on ebay), but if I can't has anyone got a spare turbo in good order??
Mines a '96 astra and has a immobiliser pickup/chip in the key, so mines immoblised too but i really dont know what it immobilises as everything is mechanical???
Theres loads of 1.7 td's about in scrappies to rob a turbo off
Judging by the wiring i'd say its just a very basic setup where the little black box waits to sense the chip and when it does it allows the starter solenoid wire to be powered up (via the yellow relay?)Quote:

Makes sense really going by your explanation.
I remember speaking to Count Vaux about gearboxes, I assume you use the big block gearbox thats attached to the turbo engine??
So I need some bigblock shafts??
What about the clutch?
1.7td are small block f17 box's iirc
Hey,
I currently have a 1.5TD Corsa and am going to mod the engine. I want to change the inlet to the 1.5 one and re-route through a intercooler as in Count's old GSi rep Corsa.
Just a couple of questions,
What size is the inlet?
Do I need to modify it in anyway?
Would a Sierra Cosworth intercooler fit?
Cheers.
Kel
My combo's N/A 1.7 is smallblock, but a brief look at the Astra's 1.7TD setup shows big block driveshafts and CV'sQuote:

indeed 1.7 gearboxes are big block boxesQuote:

How come my combo uses small block CV's and driveshafts then? I know this for certain because I bought the car with a gearbox on the verge of failure and replaced it with another 1.7 combo box.Quote:

i dunno. i just know the 1.7td's i have worked on out of cavvy's and astras are big block.
yes that's correct, It would be much easier to use the smallblock 1.7 combo box on the TD engine but I suspect the clutch will tell me to sod off
quite possibly. easiest way is to try it as your not loosing anything as youve already got it
This is very true, if it can't handle it I will fit the (I am assuming) larger flywheel/clutch and use the bigblock gearbox with a big block conversion kit.
yes i think they are bigger as i know someone once said you can use the small block boxes on the 17td but you have to run the 1.5 flywheel or something lol
Has anyone any info on this 3.1TD Isuzu trooper turbo conversion? I have found one for £60
no point in fitting a bigger turbo, the stds are more then enough to power itQuote:

32psi :p
might have been 33 even lol
Only thing is, they are tiny turbos, pressure and volume/flow are 2 different things :p
thats why i had 2 lol
We shall have to take plenty of pictures doing mine then nick, end of sept i reckon, should give me time to get a boost guage and bleed valve sorted!
Mine is doing 16psi atm, standard ic etc.
Cant get it to make no more boost no matter what i do
so you managed 32psi out of the standard turbo? Thats 2.2 bar!
well it boosted 63psi, from a 1.5 and a 1.7 turbo lol
i had 25 psi out of the standard turbo with no drop off so they are plenty capable
and so why are we not running these pressures all the time? Has anyone managed a rod out the block by running too much boost?
