Shop with Torque honing plate

Post by katrecipe »

Alright i have searched and i cannot seem to find a machine shop around the New Mexico or Phoenix area that carries a torque plate for my Ka24DE i really am not interested in paying 558.00 for a torque plate for myself. If anybody knows of a good shop that has a torque plate i will send my block there....

you can get a shop to make one, but everyone recommends that you pay more and keep it, as most shops may just make you pay for the material and then keep the torque plate for themselves.

Wait till smracing replies. Maybe his services are no longer available but it is better to know early than later.

Take a spare cylinder head to a machine shop and get them to continue the bores right through the head. Done.

Seriously now though, is there any companies that sell a torque plate for the KA? I've looked around but havent been able to find any and I want to get my block machined here shortly.

Probably not, a solid piece of 2" plate with a couple holes on it is gonna cost a couple hundred bucks to ship around. Its probably easier for shops that machine blocks, to just machine their own torque plate.

Most people dont use torque plates when machining/honing their blocks, I personally wouldnt worry about it. I did mine without a torque plate and my compression was perfect. Although on my next build I might try machining the bores through on a spare head, would only take an hour or two in the shop.

Generally no, you probably won't find a torque plate you can 'add to cart'

Reason: its usually a one time use item for most people, hence why people rent them out. To try to cover the cost of having it built in the first place. The only people that have torque plates around are companies that rebuild that engine often. Like a racing team or shop like AMS might.

Believe it or not, but SR torque plates are also not all that common, but you do hear of them more just because of popularity.

also, the fact the SR is aluminum makes a big difference too. Its a softer metal and really should have one, ka's dont 'need' it.

I'll sell you one :wink: Anyone will sell you anything for the right price.

Like walper said, no one will have a stock of KA torque plates. Any machine job shop will sell you one if you take them a head gasket and tell them to machine a plate with the bores and head bolt holes. Just be prepared to pay $500+.

my shop rejected the idea being that by the time they bore out the head, it would lose enough structural rigidity that the torque applied to the bolts would result in no difference.

i don't think many of the rebuilds on this site have ever seen a torque plate. if you are that concerned wait to you hear back from srmracing or just tell the machinist to bore and hone it very slowly and make make small passes each time. Of course with you not actually being there he's probably just going to bore it as fast as any other cast block.

If you can torque the bolts to spec, you've achieved your goal. To say that the head would lose structural integrity would mean that the head would crush under the force of the bolts, highly doubt it.

When you load up the threads in the block they expand ever so slightly. All you're doing with a torque plate is loading up the threads to simulate this so they can bore the block to compensate for it. Not having a torque plate when boring/honing creates potential high spots where the studs are, but like someone just said, usually no one uses them anyways. The high spots would be measured in the tens of thousands of an inch, no where near the clearances any of us are building too. IMO its not an issue unless you're building a full out race engine with zero clearance bores etc.

The only way boring through a head would not work is if the column of aluminum around the head stud caved into the bore you just machined, I personally dont think it would, but I havent tried it... yet.

If you wanna save some money but dont want to bore a head. Go to a local metal supermarket and order in a block of 2" plate and do the holes yourself. If you had a drill press and a 4" hole saw you could go in 1" from either side and get the bores and drill the other holes. Then just use a sander to do a decent finish and you're gold.

The block would weigh approx 19lbs, so with cutting charges etc you'd probably pay $50 for the block and $15 for the hole saw. As long as you have the time, you're good.

When the economy goes down, rare metals go up in value, lol. 8)

I'm just amazed that Jordan got the cost correct within $2.88

the cost needs to go up. It's going to take more than one hole saw to drill 4 holes through 2" plate. and dont forget a lot of coolant for the tool.

Aluminum would never dull a bimetal hole saw, it would just gum up in the teeth. If you use lots of coolant this wont be an issue.

Thanks Daigle, and yeah I'll probably end up picking it up after i buy my exhaust manifold. When I do it will be out for rent when it's not in use.

By the way I answered the OP right away. Guess he didn't like my price. No problem it stays rented out 90% of the time. Mine is made from 3" 6061 aluminum. $200 in material at the time. I used to rent it out with just a small deposit, but someone kept one.
