how did you find using the vacuum pump after drawing from inlet with the brakes? something i'm thinking of doing when i build the next car and scrap the red corsa.

it was an improvement its still piped to the inlet also just as a fail safe if the pump goes also helps with the 370mm disc and brembos

corsaZ22se

might see if i have room for one then.
cheers (y)

at last some progress
cams timed in

new 6rib crank pulley and a20nht tensioner

6rib belt to check it out need to space the alternator out more

a20nht 140amp alternator and a/c pump with 6rim pulleys on

bit by bit it coming together

corsaZ22se

how well do those alternators fit with the charge cooler manifold?

ob_one

I had alternator built smaller than my original 170amp 120 on tickover

fit straight under 2.4 manifold no cutting or spacers

ive been running one for ages far better than the cutting the bolt off and it fits with just 3 bolts some pics below of it altho the one from the a20nht is 140amp the one i imported was a 5 rib 120amp 🙂

the work continues
a/c pumps left (astra g) middle (vectra c) right (insignia) notice the larger hole is at the front on the insignia and also square cut like the vectra c

i had previously tried to fit the vec c pump and had a set of z20let pipes it was a failed attempt back then but now after turning both pipe 180* in the fitting the let pipes fitted the insignia pump and missed the rad and inlet

and still a bit of room left down there lol

the 1st try with the alternator on the cs bracket the 6 rib belt hit the alternator pulley it was then apparent something else needed to be done

@[deleted] heres the gap on the inlet from the front

after much arse scratching i decided to try again with the a20nht alternator bracket i had to make some modifications the the bracket to get the alternator off the rad pack but the belt run is now how i have always wanted it to be (need a shorter belt in the pic)

another pic of the alternator gap

you can get a 300amp alternator on a z22se 🙂 i fitted one to an "audio car" about 4years ago

corsaZ22se

Thanks Carl.
I know you fitted a 300amp one to an Astra G, I went to have a look at it to buy it but it was way to big to fit the Corsa without heavy cutting/welding to subframe 🙁
2x 140's will be better than just a single 100 amp.
should be able to get some bigger power cables on one of those as well?? 🙂
Is there a part number on it please?

that thing was a whopper the bracket i made was perfect for mounting to the a/c pump holes

made a tool for the tensioner

works 🙂

measured the difference with the a20nht belt and figured it was 90mm to long that ment it was a 6pk 1903

the modded alternator bracket

boom the 1st 6rib setup 🙂

plenty of gap from the rad 🙂

corsaZ22se

it was a bit chunky! :LOL:
would have been great for the audio car with the variable output regulator as well.
cheers for the part number, will order one soon.
that tool you made looks a lot like the one i made up. standard 3/8" bar will not go in between chassis leg and adjuster on the Corsa 🙁 small ratchet strap and engine lift bar works too :LOL:

It all looks a bit tight in there now.

(That's also what I said to my wife 23 years ago... ouch!) :LOL:

i would get a slap for saying something like that especially to your wife lol 🙂

bit more done on the astra not much progress was just not feeling the mojo
wet sanded the rocker cover
2k

g3 with a buffer much better 🙂

inlet was washed out and the laminovers reinstalled dipstick moved to fit the new alternator location
lower pump and bracket fitted then the lower wiring looms

more soon

evocarlos

got a warm fuzzy feeling now 🙂

That's what the 'ouch' was. :LOL:

(Of course I never said that to her really... I think)

KevinH

Incidentally, have you had to reroute your air-con pipes on the Astra Carl?

I know with the supercharger conversion for the Vectra B, Courtenay's do this.

originally no the pipe was just bent out of the way of the inlet on the new setup with the insignia pump ive had to changed the pipes to astra g 2l turbo pipes and turn the pipes 180 in the fitting to match the pump
with the time and effort that went into the climate control retro fit it was worth keeping the a/c 🙂

few of the little bits done today
water pipes to the inlet

top part of the loom plugged in and the charger bolted down the belts on and its staying on now lol

next up water loop and then ex manifold

evocarlos

so finally got round to doing the cooling loop
decided to keep the thermostat and mount the pump in the link tube side to retain the standard loop this way i wont need the booster pump for the heaters
added a tube to the thermostat housing

going to be tight

mock up of the 2nd tube

test fit

hole to link to the inlet of the elec pump

blank added to stop water flowing thru the link tube

installed

its close to the manifold but i will have to add a heat shield

tested the pump off a battery its noisy as the pipes in the silicon couplers are touching and i think its touching on the gearbox mount
at some point i will shorten the pipes so the pump has some dapening from the silicon couplers

evocarlos

not much done i did fit a heat shield to the water tube but after getting the engine running it set on fire ive taken it off and replaced it with a bit of alloy exhaust heat shield from the insignia

very few settings changed in the aem ecu just set from 2.0 to 2.2 and it ran needed some fine tuning of the ignition offset with the timing light it started with 530* off set and then after getting the lamp on the crank pulley it zeroed in at 554*

evocarlos

corsaZ22se

Whats the problem with them?
