+1 for staying with 920! Ive agonized over colour and still reckon that a good 920 car looks smashing. Clearly you don't scare off easily.....and having the smarts to buy other cars to steal bits form will work well. very keen to watch how this progresses. Good luck with it!

Excellent....weekend OK for you?

Thanks Mossy!

Hi all. I'm after a front crossmember 240 or 260, I don't think it matters which. I need it so I can bolt my front suspension back in and get the car off the hoist. My current crossmember is being used to hold my engine on its revised stand. Eastern suburbs Melbourne preferably. Thanks. David

I don't doubt for a minute that the twin plate wont cope, its more for those people who may want to go with a cheaper single plate setup.....they wont be able to.

And me!

Yep, that is small! Confirms that dual plate will be the only option for anyone doing this conversion.

Thanks guys. Nice to know I dont need to buy anything else!

That's sweet as bro! Bellhousing looks really small diameter, whats the flywheel size? Only ask because I reckon a large enough single plate to handle the torque wont fit.

Techflex is definitely the way to go but I need to de-pin everything to do that so its not an option. Ive ordered some 3M Super33+ as well as some Tesa cloth tape and will try both. Ive also ordered some heat shrink as well and wondering if an electric heat gun will provide sufficient heat to shrink or do I need to buy a gas burner one ?

Hi all. I'm working on tidying up my wiring harness which is a big fat bastard with muchos wires and I'm looking for suggestions on the best tape to pull it together tight and that will look good and wont turn to a sticky gooey mess in a hot engine bay. Ive used some standard black electrical tape that I had lying just to do some preliminary sorting and bunching but already after a hot day in the shed on Saturday its coming undone. Ive done a bit of research and it looks like many people use cloth tape like this http://www.ebay.com.au/itm/Cloth-Wiring-Loom-Harness-Insulating-Tape-TUFF-External-/350654058577#vi-content as opposed to vinyl tape. Does anyone have any experience with this type of cloth tape or and other recommendations? Cheers.

No, youre right. You are certifiable!

OK, dredging this one up again because I'm at a stage where I need to actually start building the exhaust. Ive done lots of research and with help from members here I'm pretty well decided on which way I'm going, key factors which are driving my decisions: Car must meet 94DB for engineers and rego Needs to be dual system right to the back, all advice says that its the only way to get the "BMW" sound they are renowned for Must have good ground clearance There are off the shelf systems from Fujitsubo and Rein Hard that look really good but Fujitsubo quote 105DB, Rein Hard don't quote DB but its a sure bet theirs is similar and at the quoted price of $2,300 its stupid money. So my preferred option is to build something myself. Key to getting the system to work, sound good and be quiet enough is going to be the resonator and rear muffler size and design. I haven't found an off the shelf resonator that will fit the bill so its going to have to be a custom jobie, pretty much like the tamiya model the Dimitri posted that runs the full length of the tunnel under the tail shaft. As far as choices Ive really only found http://www.dpe.net.au/ and http://www.surefloexhaust.com.au/frame1024x768.htm does anyone have experience with or know of customer muffler builders? Thanks.

You're wahhhhhht.......going to buy CF and then cover it up! That's one for the books.

Pete. What is the diameter of the Magnaflow resonator and do does the system go for ground clearance ?

Could be in....Hybridz linky?

.....and nomination for quiet achieve of the year is Mossy. Had a good look at this today and it will blow your socks off. Mossy has been very humble about the goings on in his garage, this will be one of the best Z's on the road when its finished. Great foresight, workmanship and attention to detail. Well done Mark, cant wait to see the finished product.

Drag Week 2012. Read a lot about this over the years and found this very cool!

Well done Simon! Lurch is correct....and the wife will kill you when she sees the picture you've posted. Good luck with that.

Peter. Its scary how similarly we think! That's pretty well what I'm envisaging doing, dependent on how visible the cables are once everything else is in place. I still reckon they will barely be noticeable given how low down the firewall they are. PS. Love your gate fabrication....and I don't mean garden gate.

I could, but as stated from the word go I'm trying to keep the car as original as possible and try and make the whole conversion as reversible as possible. I did cringe when I took the grinder to the tunnel but half an hour to cut a piece of sheet and weld it back in will see it rectified back to original. Cutting holes in the plenum isn't something I want to do just for the sake of hiding the battery cables. The -ve cable also carries all the wires for the diagnostic plug which is massive and while I could make a connector plug so I could unplug it and draw it back through the plenum for engine removals it just isn't warranted. They battery cables will be barely seen anyway once the airbox is in place.

....approximate location of battery cables.

I still need to do a final tidy up of the harness and add some split conduit but it all sits well and will look OK when its all done. Once the airbox is in place the only thing you will see in the engine bay is the battery cables running across to the battery in the approximate position of the last photo. The next thing will be to mount the ECU, relays and all the EWS security bits on an aluminium panel above the passenger foot well.

Wiring time! In the first pic below you can see how the standard engine wiring harness is housed in a big ugly plastic box, which in the M3 engine bay hangs from the firewall and sits over the back of the cylinder head. The box doesn't look out of place in the M3 engine bay as there are plenty of other plastic trims and covers but its wrong in the Z bay. I want to keep the engine bay as clean as possible without going to the extent of completely hiding all the wiring, in addition the +ve and -ve cables to the battery are on the wrong side and the other issue is that the plastic box sits right where my bonnet catch bracket is......so time to redo the harness. I need to bring the battery cables across to the correct side, route the main harness down and behind the cylinder head so it cant be seen and then bring the main ECU plug, relays and the plug that normally connects the engine harness to the body harness inside the cabin. These also need to be easily unplugged for engine removal. On the M3 the ECU, relays and harness plugs are all in waterproof compartments in the engine bay and understandably so as there is probably 120 wires all up, this results in a very thick harness that I need to bring through a grommet and like Peter Allen the trans tunnel is the best place to do it. After lots of research on the interwebs and 3 trips to pick a part I found a good grommet which came from a 2002 BMW 535. The shape and OD is big enough to get the bulky plugs and relays through and the ID is just the right size for the harness.
