Crank pully questions

[Tofuball]

I have a 3.4HT, and I was trying to find a way to affix an 60-2 ignition wheel to it, as I am looking to upgrade my ignition system (I have a MegaSquirt ECU, so I don't need to really worry about what pickup is compatible with what)

But then I read that the 2006 Monte Carlo's V6 engine already has that.

Does anyone know if they are interchangeable?

Failing that, know any crank wheels that have a ignition pickup in them?

Then, finally failing that, anyone with the right tools capable of cutting one into my stock pulley for some cash?

Thanks in advance!

im guessing you are going to run 3 ignition drivers in the megasquirt and controll the coils directly. you can find generic 30-1 and 60-2 trigger wheels on e-bay, you just would need to make it fit the crank pully. another option would be to use the external trigger wheel sold from the 60v6 store and run a gm coil module (the trigger wheel is 7x).

the 06 monte, im guessing a 3500 or 3900, has an internal 58x crank trigger (60-2) built into the crankshaft, so its not easily used.

If you have the HT 3.4L check if the reluctor wheel is machined with groves on the crank. Then you could use the stock sensor. Easy to do and cheep.

If it's the crank that came in the motor from the factory, you should have a reluctor wheel on it along with the mounting location.

Are you able to get the oil pan out with the motor (in that VW of yours,lol)?

Are you considering a top end swap? If so, I have a complete 3400 top end I might want to trade/sell.

Correct!

Thats a pain to do accurately, and mounting that sensor, but I'll do it if I have to :P

I was about to! But they're sold out. Also, I don't get as fine control over things as with a 60-2 wheel.

Well, crap. :P Thanks for the info.

Hrm. you think my block comes with it? What exactly am I looking for, do you have a picture? Is this under the front cover or do I have to pop off the oil pan?

SWEET.

Yeh, I can drop the engine out of this thing really easy. I have four really long bolts that lower the whole engine cradle to the ground and then let go. I don't need an engine lift or anything, it's great.

Yes, I am considering a top end swap, this Fiero intake is garbage. I got a 3100 engine for free out of a 95 Lumina so I'm doing a heads, intake, and ignition swap.

What has the 3400 top end got that I could use? I could definitely be interested if it ment I could keep my "iron head" pistons and still switch to the better, lighter head and the lower profile, better flowing intake manifold.





Thanks for the responses so far everyone!

The top end I have is similar to the one you have, except larger valves and ports (170 casting). The top you have won't flow as good as the late 3100 heads, but you will see a big improvement over the iron heads.

You are still going to have to change the pistons unless you don't mind high compression. The 3.4 comes with 8cc dished pistons, in combination with 27cc chambers, well...

4qs

1) How much bigger are your ports? really worth the effort?
2) What do you want for it? (Wanna trade parts? )
3) how high compression are we talkin? Would the pistons from the 3100 work or would I need to buy yet another set of pistons?
4) Would the UIM from my 3100 work with your 3400, or are you including that?

Thanks!

That article shows the location of the Crank sensor.

1. A few mm's, but the valves are also larger
2. Depends on the trade, but if I sell, i would like at least what I paid
3. 3.4's have 8cc dishes, 3400 heads have 27cc chambers, IIRC 13.x:1. No the 3100 pistons are smaller than the 3400 bore (you could sleeve if you wanted).
4. I would rather sell the upper end as a unit

The upper I have will flow better, but you will see a big gain over the iron heads. Here sre some comparison pics...

That compression is way too high :P

I just need to figure out where to get a set of 3400 pistons then. Would they fit my 3.4HT? Any idea on a good place to get some?

I'm looking also, but since you need them before me...

Sweet! My block has the provisions on the side for the knock sensor and the pickup sensor. I'll just steal those off my 3100 block.

Thanks everyone for your answers, now all I have to do is check the crank for the pickup.

ForceFirebird: Want an Eaton M90 in trade for those heads? What engine did those heads come off of?

PM'ed back.



Anyone happen to know offhand what size freeze plug I'll need to plug the dizzy hole? Do I have to plug that oil hole too?

You will need to replace the dizzy with the oil pump drive assembly from a DIS motor.
