Dont mind at all 
On the back of engine just above the water pump outlet there's a blanking plug in the oil gallery i'll take the feed from there and weld a return into the sump, it's a kkk k-14 turbo off a 2.8 iveco daily, I'm not after too many ponies (180-190) i'm more interested in a responcive engine so i'm keep the pipe work short by making a charge cooler over the gearbox and a new inlet manifold with the throttle body on the other side.

Nice project 
Wish i could turn my car into out and out track car, the girl friend would moan far to much though

True, although i can barely hear her as it is now, the 3" turbo back exhaust is pretty good at ending any conversation im not interested in

hmmm interesting. ive never noticed that blanking plug. ill have a look the next one i work on.
what boost pressure are you thinking of running to get the 180-190 mark.
i think you will be better off putting a front mount on there than one over the gearbox. it will lower the charge temps so much more and will equal more responce/power. unless you want the turbo conversion to remain a secret from the outside of course!!
are you doing any internal work

Tis very true my old car was totaly stripped as well no sound deadning, can be a bit much on long runs
It's going to be charge cooler (water filled) with a motor bike rad at the front of the main rad and a small pump to circulate.
Looking around 14.5 psi boost any more and the turbo will start to surge, internaly i've ported the head i've got some xe rods (forged rather than cast) piston wise i might try to machine the xe ones to lower the cr (need to have a good look at them first) or get some out of a let or somthing else suitable?
new bearing's ect, metal headgasket stronger rod bolts. I'm in the process of learning how to tig weld as i'm baffling the sump at the moment.
It's all going to be running on my megasquirt2
I want the outside to still look the same as standard, I'm using the standard 14" wheels

Be careful machining the pistons! And if you do, match their weights as close as you can (im sure you know this, but better to say it than not). Also, if you just want to lower the cr, can you not just fit a thicker hg? Or will this not be enough of a reduction?
For a 1.8, 180bhp is a pretty moddest figure, so wouldnt think you'd need to reduce the cr that much, especially as i dont think the original na setup would be that high of a cr anyway?
I must admit, ive not worked with vauxhall's, just applying the theories aquired with jap cars ive owned.

You lose too much squish with a thicker head gasket and these engine like a good bit of squish, i only need a little out of the pistons (forged 16v ones) but it might be too much i'll have to look into it, but i'll take a bit out of the combustion chamber as well to unshroud the back of valve to try to improve the swirl. As standard it's 10-1 cr so pretty high. Getting it down to 8.5 - 1 will give more room for error with my mapping and being able to deal with hot days on the track (or b road)
Better to aim for a modest figure and be suprised than be disapointed

Yes of course, didnt mean it like that, just thought you may want to retain some cr for off boost performance, especailly as your not going crazy with the boost Not sure on the size of the turbo, when are you expecting it to be fully spooled? And whats your rev limit going to be?
Releaving the chamber is definately a wise move, especially around the back of the valves.
Sounds like a great project, certainly something i wish i could afford to do with my own car.

Not 100% certain but hopfully full boost around 4k but i've only got compressor maps and nothing on the turbine rev limit will be 6.5 to start with (standard) but should be good for 7k but it's the followers that seem to be the weak part (they fall out) stonger valve springs will help but i'll have to see what happens...
rattle rattle clatter bang
I'm not spending too much on the engine internaly to start with to see what happens.
The turbo was free (nearly new) and the manifold was made out of a couple of old tubular manifolds, all in all i havent spent alot just a lot of time waiting to find right parts and making bits fit.

So where to start with a update??
It's almost done, but on the second engine as it ate the crankshaft before it hit the road! Note to self dont buy a stripped engine that been partly put back together!
Finished up the paint.

Painted in the logos and tailgate strip.

Astra Gte by ben a.k.a me, on Flickr
Then put lots of bits back on..

Made some ITBS direct to the manifold, used some durafix rods and the OA set. But bonded the bodies onto the manifold to stop the heat damaging the seals
Astra GTE by ben a.k.a me, on Flickr
Made a airbox to go on the bodies
Astra GTE by ben a.k.a me, on Flickr
Whipped up a side exit exhaust out of several other unused ones and made a XE manifold fit my later XEV engine.

Added a few spherical bearings to the front end, turned up some delrin ones for the rear. Moved the suspention pick ups around a bit to add a lot more caster. Mostly in short it's all been either stripped, rebuilt or made
Lots more pics here.

Years ago when I started the project, yes I was sticking with the 8v with a turbo nailed on the side. But recently I went for a 16v ecotec instead as it's easier to get parts for now off the shelf compaired to the 8v . That and the head can flow a lot more than the 8v ever will.
