Phase II - saab head + 11:1 CR

vocky

so with the plugs removed from the engine I cranked the engine with the starter to build up the oil pressure, it seemed to take ages before the oil pressure built up (glad I primed that oil pump)

once I had a healthy 75 psi I checked for any leaks, the usual vx220 filter lid had a small leak, a minor tweak with a ratchet had that sealed 🙂

the old favorite returned, no clutch :o but that was simply the connector clip hadn't quite engaged and the pedal pressure 'popped' the joint apart, so that was easily sorted :thumbup:

then I fitted the saab NGK Iridium spark plugs and modified the coil pack to ensure the extensions reached the plugs, life is never easy is it :eh:

finally it was time to start the engine, started first time woohoo.gif

That looks great vocky very OE, when do you think it is going to be done, Was the cover that baby blue from OE or have you had it sprayed that way?

I'm still getting the air out of the cooling system, it's not an easy task on the vx220 and takes several hours :wtf:

Due to some other mods I need to fit I'm not sure when the clam will go back on dunno..

I painted the z20net cam cover myself, the colour is usually found on ceratin RS model's of the 1970's :lol:

next job was to fit the head, then set up the cam timing, normally that would take a few minutes but I've used GM vernier sprockets so it took over one hour :eh:

the inlet cam had to be adjusted about 6 degrees and the exhaust just 1 degree,

Which method did you use for the timing ?
On a freshly built engine you have no oil and no pressure at all in all the hydro tensioner and lifters, there is normally no reliable way to have it done with a good precision without using "fake" solid lifters and a mech chain tensioner

I know what you mean, but all you can do is set it up the best you can, even if you used 'fake' lifters changing back to hydraulic would alter the timing anyway dunno..

Just in case anyone wants to know how to set up vernier sprockets....
(sorry no pics as my camera batteries died when setting the timing up, bought some new ones now)

I fitted a degree wheel to a spare crank pulley, made a suitable bracket so I could mark the timing positions. Next set up the tdc by marking 0.1mm before tdc and 0.1mm after tdc (using a dial test indicator), then marked the centre position to get tdc.

then used the same method but on the spring retainer, example stage 3 cams; 112 degrees for the inlet cam, so measure 0.1mm before maximum lift and then check the degrees (perhaps 100 degrees) then measure 0.1mm after maximum lift (perhaps 124 degrees) 124 - 100 = 24 / 2 = 12, so 112 degrees = spot on

The bolts were loose on the vernier sprockets, so I just tightened them. Strangely the inlet was spot on at 6 degrees :wtf: so I double checked to confirm, then I set up the exhaust which took a while :lol:

a pic of the modified webcon wiring loom, I have changed it to make it look more factory fit 🙂

Looks smart Vocky how do you know all you do about engines??

wow thats amazing vocky.
well done to you.
i bet when u first tuned the key you was shitting your self.
nice one 😃 😃

great work.. but baby blue? :sick:

it matches my brake calipers :lol:

it will look better when the clam is on 8)

Outstanding work neil......Know when this is finsihed are u actually goin to use it lol....

I suppose it's just experience, but engines are not really that difficult, especially compared with some of the equipment I've fixed at work over the years :lol:

I did so many checks before firing it up that I wasn't bothered, which is a first for me :eh:
Normally I panic when the engine oil light stays on, but I cranked the engine until the oil pressure was good, then fitted the plugs and started it up 😃

hopefully it will get more use in 2009, I have no plans to modify it at all next year :o

well only a few minor mods :lol:

Sjdickso

I do like the baby blue, its just different.

Look forward to seeing at some shows next year.

Absolutely fabulous Neil. Really pleased for you. It looks so right. I reckon we need a winter mini meet at your house to come and drool over your work.

;-)

vocky

and the (almost) finished pic :clap:

alanoo

Next time, do it in pink :lol:

Matt

Fantastic work Neil, looks great, and I really hope to see your 220 at some point in 2009 😃

sdbutler10

that looks amazing under there 😃

blue_se2

Looks awesome neil well done now is all ya need is some sun to take it for a test drive lol

a rather poor video, the sound is muffled compared to 'real life' :think:
