Was wondering the other day. With aero catches might be a bit hard to pull if there is a fire under the bonnet..

looking sweet man!!

You guys are hilarious. I am kind of fond of the screwdrivers.

I have fitted the bonnet pin setup from the steel bonnet for the time being, and have hedged my bets by ordering both the aero style and some new black 'Sparco' bonnet catches. The main issue I see with the aero style, is due to the size of the hole you have to cut to fit them, once they are in you are stuck with them.

You have the aero catches on yours don't you Aaron? I will have a look at them when they turn up. Aero wise they will be significantly better than the conventional style. I plan to run four pins, not the two I have now just to make sure the bonnet is good and secured.

I will be ditching the steel bonnet I think. I don't really have the motivation of cleaning it up and repainting it to sell it. Might offer it free to local guys if they come take it away.

I still haven't fitted the boot. I am not entirely happy with my wing mounts. I would prefer they went through the rear bumper area direct to the sub-frame, rather than through the boot as they currently are. That means I don't really want to cut slots in a perfectly fine carbon boot. I might look at it in the new year.

Yeah ben I have aerocatches on mine. Make sure buy genuine some mates bought the cheap ones and quality isnt there. All the hex countersunk bolts stripped out when tightening. Is a bit more to fit but looks and works alot better. If you have a look on my thread should be pics there or ill pm some pics over fb

Car is loaded upon the trailer ready for my final outing at Mallala tomorrow. It is just open practice so it will probably be hectic and hard to find space to turn some good laps.

Basically looking to test the bonnet and roof, and see if gapping the plugs down has helped with the misfire. I will be taking the 20 year old cracked coils as well, and will swap back to them if the Supersparks are still no good.

Sorry I couldn't help you out in time! I've been studying basically all my waking hours (dynamics and control exam tomorrow, mechatronics exam next friday) so yeah... :-(

But that said, I'd be totally keen to help you out remotely if you want le cheap coilpack upgrade. My plan was to measure it up myself and make the loom and give it to you but fitment is really very easy, no reason why you couldn't plug it in yourself. Only thing I can't do remotely is find your fused power + ground (of min 16A capacity) and connect it to the ECU. That said, it's pretty damn easy; Could just use crimped spade connectors if you wanted...

Either way, good luck have fun tomorrow!

I am still keen to do it. I would like you to see the car before you make something. I had the entire engine bay rewired from scratch, so I am not so sure it is even remotely similar to stock.

Well to be fair my plan was just to make it very long and give you the freedom to make the cut where you see fit. I mean, all I'm really doing is splicing some connectors onto a bundle of wires - I can make them as long as you need them to be. I promise to call my favorite wreckers next week and get prices on COPs for you; I built this system because I like cheapness and I don't want to encourage you to spend more than you would on another guaranteed solution (like the driftmotion std 1jz coils @ $750US+post)

SPent the day at the track. Car ran pretty good with the plugs gapped right down, but it really needs to be sorted in the long run.

In the first session I was basically just shaking the car down. I still bettered my PB with a 1min19.0s so that was a good start. The car was very loose in the rear. I didn't go flat through the kink, and had both lift off and power oversteer. I need to run a string around the car and check that my 1mm rear toe is in not out. I am suspecting it is out.

Second session, no changes, the car ran a 1min18.4 seconds. Still loose in the rear.

Took a pound out of the tyres for the third session. On my first flying lap of the third session I heard a knock or tap from the motor. Pulled it straight into the pits and it is definitely coming from the engine, likely from the head. That ended the day before it really started. The car would have run 1:17, because the optimal lap of session two was 1:18.0 and the track usually grips up as the day goes on.

That time would have placed you 15th on the grid at this year's nationals sports sedan round at Mallala, just so you know.

I have 8 spare COPs, if you want them, with the plugs from the loom.

I really don't see the point in going for a jerry rigged setup, when you can buy the real deal at a reasonable price.

Thanks fellas.

15th on the grid. Happy with that and it puts it into perspective, even on semi slicks. I have posted times in one of the track times threads.

Jeff- I am very interested in Matt's idea. I like the idea of 20 years of development and advancement in coil design for less than the cost of a direct factory replacement. The way I see it: I am still buying OEM quality control and reliability, just 20 years newer. I would like to think that they didn't spend 20 years making the coils worse, especially the intense focus on more efficient combustion that occurred in those 20 years.

Tell you what - if it doesn't work you can say I told you so. I wish someone had spoke up when I was buying the Supersparks in the group buy, because then I would be $500 better off. Usually I wait a while and see how it turns out for others before jumping on something new. To be honest though, until I started having problems with them I had never heard of others having issues. You win some, you get ripped off some.

Yeah... I bought a Microtech once. :-(

My setup, once installed, should look much cleaner than stock setup, eradicates ignitor, shields the COPs from heat and it's using COPs that are much newer. Oh and don't be concerned that I'm doing it for the money... It takes me about 3hrs to make the loom properly and I make about $30 profit on a ~$550ish setup.

Bear in mind again that my main advertised advantage was being able to replace COPs in the future for $50 in great condition instead of $200 from Toyota or $80ish second hand gamble :-)

OK gents. I have just about reached the end of my talent. The cam covers are off, the coil packs are off. I can't see anything glaringly obvious so far.

My next step tomorrow night is to pull the plugs and see if one looks different to the rest. I am going to ask around for a bore scope to borrow to have a look inside. If I cant see anything obvious then I will have absolutely no idea what to do next.

Happy for any suggestions from those in the know. To recap: after a warm up lap in the third session of the day I dropped the hammer and got up to speed. As I went down the main straight and got on the gas in third (6800 rpm shift according to the log) I heard a tapping of knocking noise. I rolled another 100-200m to figure out if it was speed related or engine speed related. It was definitely engine revs related. In the pits there was a definite tap, tap, tap and it sounded like it was coming from the right rear top of the engine. (as best I could tell) .

What next?

Have you tried turning it over with the cam covers off? Might help identify it.

Things that go tap; exhaust leak, worn shims, big end bearings, slapping piston. Most of those would result in major loss of power, if its not down on power it's probably not so serious. How loud is it? Has it had performance valve springs fitted? Are all the shims still in?

Andrew,

did that this afternoon with some light. Could not see anything out of the ordinary. There was also no discernible sticking points as I turned it over.

Clayton,

Thanks. The valve springs etc are all standard. It was loud enough I could hear it in the cabin with a helmet. I didn't drive it far enough to figure out if it was down on power. The shims are all still sitting under the cam lobes, and there is no metal debris anywhere in the top of the head.

I pulled the plugs this arvo and they are all identical.

I borrowed a bore scope/camera snake/whatever it is called from a bloke at work. I have inspected the tops of all pistons and there is no debris or witness marks etc. All the valves seem to be moving freely, and they are all intact as best I can see through the camera.

I could have sworn the noise was coming from the top of the motor, and towards the fire wall.

I might have to put it all back together and start it again to try and narrow it down. At least I know it isn't a valve or part there of bouncing around on the top of the piston.

This may sound stupid but have you checked around the fan shroud or maybe listen to the pulleys at the front of the engine, anything that rotates.
I also had very load ticking coming from a loose plug lead arcing on the dizzy.

Don't forget to check the studs on the exhaust manifold; a slapping manifold would give the sounds and lack of sounds your hearing.

Noting the inspection that you have done, I would install the plugs and covers and without the coil packs, have someone spin the engine while you make another inspection under the hood.
Did you check for codes in the management system?

Change the oil and take the lower sump off if you want to be totally certain that the bottom end is safe. If you've chewed a bearing badly enough to make a distinct sound there WILL be debris in the oil.

Totally sounds like an exhaust leak or other peripheral though... a bad head will be relatively easy to spot.
