Hehehe, well.... not a hell of a lot has happened since I last posted over a year ago!!! I actually got to a point of trying to start the engine, but it didn't... then for some reason the fuel pump won't turn on anymore, the computer doesn't seem to be sending the signal to the relay to turn on... C...

mines just stamped where it normally is on a Z series

my bad, I was just taking a stab at what seemed logical... and how squirt works

the computer must be getting RPM from somewhere (probably from the coil in your case)... once it sees any RPM it should be running the injectors, thats how it knows the engine is cranking, because it will be turning over at around 200rpm.

using a 2l head gasket on a 1.8l will cause the compression to drop slightly (I worked it out months ago, can't remember now, think it was around .25:1 so say you had 12:1 compression before, would drop to 11.75:1 compression) However, having a small gap there will quickly fill up with carbon deposi...

you'd need an intake air temp sensor, and a coolant temp sensor, also need efi fuel pump and all other efi gear required as a minimum. then the list goes up from there depending on if you want to run ignition, and how you run it... I also had to install a crank angle sensor... Plus do lots of wiring.

the downside of the mega squirt is that you either have to build it yourself, or pay someone else to build it (still, getting someone else to build it isn't a downside really, as it is still cheaper than others), and that it being able to be tuned in real-time it is defectable yes. Also, a sort of d...

it has also been proved by various people (main one that comes to mind is creators of the megasquirt/efi332) that sequencial injection doesn't actually provide as much benefit as it would seem. This is mainly due to the fact that on a normal engine, at revs over idle, the amount of time to squirt fu...

did some wiring on the weekend. IAT, CLT, TPS, CAS all work I had previously bought some twin tower coil packs off an ecotec commodore but found out on the weekend that they require a seperate ignition module to fire as they draw 36amps to switch! I took them back to the wreckers to swap for coil pa...

my ecu arrived this week, so I'll be working on it on the weekend, hopefully it'll start in not too long! woohoo

my engine has always run FUXS oil, but I would suppose any high grade (not cheap shit) will be fine... something like 20-50W

sorry, I don't have a stock throttle body on my engine, so don't have any of this...

ah, water doesn't go through the throttle body... I'm assuming you are confusing the idle air control valve with something to do with water because it is mounted on the water inlet manifold... it is only bolted to that so it warms up with the engine coolant temperature, but it passes air into the th...

pretty much can't get a sump gasket for the twincams

try slightly tightening the bolts (note, they should not be done up tight, just done up so the gasket is being squished a bit). or try putting some silicon instant gasket on the rubber aswell if there isn't already some on there.

the original question wasn't if I could run ULP or PULP, I've run my G200z on PULP for years... it was if legally I had to fit a catalytic converter with a G180W. I'll just ask my engineer before I get the exhaust made.

actually. its a lot easier to use the image hosting function from imageshack that poida has implemented into this forum... When you are adding a post/reply, at the bottom you will see an image hosting section with a text box and a browse button.... click browse, find the file on your computer, then ...

gem gave me two mobs to talk to a while back about things for dohcs, such as piston rings. I haven't talked to them yet because the need hasn't arison, but give them a call if you'd like.... Gem sourced his total seal gapless rings from the first mob. APEP (Australian Precision Engine Parts) in Melb...

head bolt torque is 10kgm, or 98nm

I can't remember in what way, but SOHC rings are 0.4mm different in some way... I found this by just doing a google on rings for the twincam or something, and found a catalogue for some company in japan that had different part numbers to the SOHC and DOHC and one of the measurements was different by...

my engine doesn't run yet, so no

but yes, it will definately help, the stock one is rather restrictive... the only thing is they might be a little on the too big side, but I won't be sure till I get it running, which should be soon.

since the size of the hole in the plenum is the wrong shape and size, rather than make an adapter plate by far the best choice is to bolt the tb directly to the plenum, and use a die grinder to make the hole in the plenum face match the tb size and shape. To mount the tb to the plenum you will proba...

under the assumption of it being a race engine (HA) good for about 100rwkw (HAHA) and it being ready to bolt in (HAHAHA) including him driving it up from adelaide to brisbane it cost me $1500

10.5kgm comes to mind... I'll check when I get home, but I definately have the answer at home, so don't delay taking your head off till I get back to you. I just had the head off my engine couple of months ago.

I don't know what you are going to do with visual basic and a delco 808? but I'm actually a vb.net developer by profession
