Completely different motor, and I doubt they'd fit for depth or design. You'll need to find connectors, tip's, the wiring diagram for them, etc...

And there's no such thing as a PnP COP. The Toyota ones are a perfect fit for their depth, but still require some slight Dremel'ing to fit in the valve-cover channel (on my 1.6 at least). And you still need to fab the wiring harness.

Don't make this thing harder than it is. Look on eBay, find Toyota 1ZZ-FE 2000+ COP's, Dremel to fit, fab up a harness, install resistor into diagnostics box, fabricate hold-down plate, install, turn key.

Read this, it's easy to do it:

Go back and read post #1027. It's not sourcing the COP's that is the problem... it's that there are at least 4 different 1.8 valve covers (maybe as many as 5). The 1.6's are all the same, but the wiring for the years of 1.8's are different as well.

This thing IS EASY!!! It's a great mod you can do yourself on your kitchen table. Why pay somebody three times as much when all it takes is a little sack to attempt something new. Go out and buy a soldering iron and make it happen! DIY BABY!!!

i back sams attitude on this, i was friggin scared as hell, i dont know anything about wiring etc. the i build two harnesses and even though i have not installed mine yet, it was confirmed that the way i build mine works great (ask Saml01)
just give it a shot, you'll be happy you did it yourself and saved $100 and spent it on hookers and blow

The different coils have different distances? Or just angles? The one I have has a different angle from the four I used, but the distance looked very similar.

And buying a 1" drill bit was awesome. :-P get a stepped bit, then put in a rollbar to justify the expense.

You need to be introduced to the hole saw

That's what I ended up with, a hole saw. But I still like the stepped bits, they work so well so much of the time.

Smile Dibs

Whoooo, Just read all 55 pages in one afternoon. God bless these reeeeally slow office afternoons

I really like the look of these COP setups and anything that boasts more power, smoother driving, better MPG and clinicly proven to look 190% cooler than stock is on my list of things to do (especially if its cheap!)

Well seeing as someone has let the magic white smoke out of my stock coil now would seem to be the perfect time to do this conversion

Ive found these, can I call Dibs?

http://cgi.ebay.com/ebaymotors/Toyot...spagenameZWDVW

Brainy listed these as working nicely, how much should I be looking to pay?

These coils are HARD to find in the UK so if anyone has a nice set of 4 pref with connectors for sale and wouldn't mind shipping to the "United Kingdom of expensive and unavailable parts" please let me know as I dont really want to wait for 9 days on ebay only to be outbid by some tosser in the last 0.1 of a second.

Or are there any more group buys going on? I know I came a little late to this thread but I only got my car 2 weeks ago. What ya gonna do

Thanks in advance

Tom

I have those same ones, the fit is perfect and they seem to be the most common ones on here...
look at car-part.com and see if you find anyone who will ship to UK.
Anything under $100 for COPs is a decent deal, since you are in the UK you will obviously pay premium due to shipping. Do you not have Corollas in the UK or what? lol
go to a local junk yard and just gid around.

We have plenty of them but there just doesn't seem to be any deals to be had. None of my local junk yards have anything usable. (I reccon thats down to Brits being as tight as Mother Theresa's..... and fixing anything younger than 20 years old) The only way to buy used coils in the UK is to pay $80 each (penny pinching ripoff merchants)

Anyhoo Ill get me a bid on those ebay ones (especially as they have bonus conns)

Those coils are mine!! Any one who tries to steal them from me will be killed untill they die from it!!!

I know I should search all 55 million pages for an answer, but I'm just gonna ask... Does anyone have the wiring diagram for the OEM COP for my 2001? I want to switch it to the real COPs.

I paid $70 shipped for mine, but they've become VERY popular in recent weeks. I'd expect to pay over $100, and I'd send a message to the seller to see if he'll ship to England cause it doesn't indicate that he will.

The last thing you need to do is upgrade your ignition. Get boosted and get tuned first. Y8s did the swap though so he would know.

Nothing wrong with making plans for the future. I would have already bought coils and such if it was an immediate plan. I would not do it all at the same time, that just would be unintelligent.

yes
you got a ground power and trigger. lol
the middle one is the ground if i am not mistaking and you just give ignition to find your 12v with a basic volt meter or something. and the third is the trigger which is the only on left.
if you are looking at your pins inside the connector. they are facing you from left to right

Sorry, I didn't know that it was funny being unsure which pins were which.

Thanks.

Yay!! I got my COPS gonna have me a solderathon tonight to get em up and sparking. I'll post some pics when they're done.

Also Whilst taking apart my old coil setup I think I found another source for the plugs to go to the stock harness rather than chopping up old coils. On my 94 1.8 S Special the plug that goes into the CAS is identical to the coils. The socket on the CAS also looks like it could be removed without excessive "dremeling". So if you have 2 old CAS you're laughing.

Also a small question about timing guns, I want to set my timing to 14 BTDC and I borrowed a timing gun from a freind. Its quite old and has a **** on the back that adjusts the delay so if you dont have a scale then lining up the spot on the TDC mark the gun will show you the advance. My concern is that the accuracy of this **** is in question. Do you reccon if I short out the pot it will show 0 degrees shift? Or should I get a different gun?

Thanks

Tom

Hole saws will work, but I like precision.

That is not at all un-nice. Do you have any pics of the bottom of the plate (i.e. how far down does the screw head protrude)? What's the material, how thick?
