TIII billet aluminum mechanical rockers being tested.

[MOPAR2YA]

Been working on this for a while. They are going through testing to check wear/geometry etc. Afterwards will get additional lightening etc and a group buy in will be announced. Pricing not set, but should be in the area of the price of replacement hyd lifters.

I know of someone else that has been working on these, as well. What's the roller diameter and rocker ratio?

Still cool to see someone else working on products for these cars.

Looking forward to your vendor status

subscribed! good luck with the project

Ratio is same as stock with a .739 roller.

I think Simon going to have a chubby reading this!!!

How far off are these? I need to work on my rockers and lifters and if these aren't too far off, I'll wait and get these!

Boing, lol.

I'd be interested for sure, not sure If I need them as I do have the updated lifters, but the price sounds wicked,

What about an option to reuse the stock lifter?

Any pics?

I'd suggest using the lifter/lash adjuster from a SOHC Neon engine, they are very close to stock, but (currently) plentiful in the JY, just have to drill a hole in the rocker arm and push them out...

Good idea,

.739 is somewhat close to what the original diameter is. In talks with UltraDyne last year about my cams, we found that a larger diameter wheel would be beneficial in the T-III (like in the step you are taking) but.... if increasing the wheel diameter, then the cam should be ground in accordance. Changing the wheel diameter changes the timing events and ratio. But you might get lucky and it might be a good thing... or a step in the other direction.

I already beat you to it last year http://www.turbo-mopar.com/forums/sh...n+lifter+t-iii

If it's not too late Wallace, you probably really should consider using the sohc lifters as they are super close. Not sure what they cost new, though.... But there are actually a LOT of small lifters out there similar to the T-III from what I have seen on other heads.

If I was a betting man... I bet Wallace also has some solid lifter/rockers in the works with the matching cams. But if this is true... then maybe he oughta invest in reproducing T-III VC seals, too.

I don't think you will ever have to worry about replacing lifters again with Wallace's design.

[shackwrrr]

I would much rather have mechanical adjusters. No worries, adjustment should last over 60,000 as long as the rockers don't deform. Look at the Suzuki 1.6 motor its mechanical.

Steve, I discussed the larger roller with Elgin Cams, he said it would work quite well, doing what you described. It would be like a Stage .25 cam. The rockers are mechanical, but I can look into what a hydraulic version would be. I have to admit I dont know much about Neon lifters, would they handle the larger TIII mass? The mechanical set up is set to rev to 10,000 rpm and has a replaceable roller. The prototypes are pretty basic, are in raw aluminum and havent gont on a diet for lightening like the production pieces will, so they look, well, frumpy. We are going to put some miles on them and see if everything checks out. Updates to follow....

The mechanical set up...has a replaceable roller.

I'm excited; and will start budgeting.

[turbovanman²]

Replaceable roller, that's the best part,

well whats the scoop

Takes a while dude! R&D should be more than just a couple weeks on a car, as I'd prefer more like several months. Then, they need to make a final design as I think he said the current ones are a bit rough/crude.
