We need a complete list

[supra8903]

We need a complete list on how to rebuild a 7m corectly. Everything that should be done, and things that should be left alone. From HG to oil sump, what needs to be done to build a bulletproof 7m, all in 1 thread. Theirs pieces out there, but it needs to be put together. I want a complete how to build a bulletproof 7mgte.

Also we should have a where to get the work done: shop, location, price

 

[Supra]

Too many different opinions on this to ever make it happen.

 

[mkIIIman089]

Umm, I don't think we need a complete list.

 

[supra8903]

im not saying use brand x pistons, im saying work that needs to be done... to build a monster, like alter the oil sump, or options for a new one,

I was looking for: THESE ARE THE WEEKNESSES, AND THIS IS HOW TO FIX THEM.
a complete list...

 

[jdub]

I got an idea...you read the TRSM, research this site, make a list, post it and we can add what you missed!:joshers:

 

[supra8903]

I have searched there are a ton of: "this needs to be done"... I was hoping for someone who has done it to say, this is what needs to be addressed when rebuilding a 7m...

 

[JustAnotherVictim]

That doesn't stop you from starting a list yourself.
Take some initiative, people have already offered to fill in things you miss.

 

[jdub]

What you're asking for takes a lot of time. A suggestion...research the head and make your "to-do" list...post it with your questions and modify your list. This does two things...it gets you very familiar with the workings of the head and it sets your "path" firmly in your mind. Do the same for the bottom end, but use a different thread.

Once the guys on here see you've thought this out, you'll get all the help you need. Keep in mind you will see various opinions on what to do or parts to use. For example pistons...forged or not, the brand, what rings. Guess what? They all will work depending on your HP goals...that leaves the decision up to you and a lot of times $$$ will be a big part of that decision.

To get you started, I posted this on our local site...it talks about some of the stuff you're looking for:

On this site (SM), focus on the Rebuild and Reference section...a lot of info to help you.

 

[TurboWarrior]

Did you read the faq. Theres a thread in there that is very very informative on what to do for a complete rebuild. Also on SOGI under "General Headgasket Info" or something

 

[Justin727]

read a few build threads mang

 

[supra8903]

ok well what about the second part of my post... where to get the work done...who does a good job

 

[RTA Supra]

I know what Supra8903's getting at, but like everyone is saying....the info is out there. The FAQ section is a great tool that has a lot of the time already devoted to some of the biggest issues with our car. Anyhing else can be searched, and if needed you can start a thread. That's what SM's here for

 

[RTA Supra]

As far as where to get work done, start a thread in your region section. SupraForums has something similar to what you're looking for.

 

[TurboWarrior]

Its hard to say where you should get it done. Youll have to find out which local machine shops are equiped enough and skilled enough to do the job properly. Unless you want to ship it somewhere.

EDIT: ^what RTA said

Theres more but I found these the most helpful

If you're looking at local shops, the biggest consideration is "do they have the equipment capable for achieving an RA spec in the 30-50 range for decking the head/block?" That's what a MHG requires to seal properly...most shops do not have the equipment that can do it. And don't listen to them when they say "you don't need it that smooth"...they want your $$$...just walk away.

Most all other machine work can be done properly by a competent shop. If you are planning to over size on the bore, make sure they use a torque plate.

 

[JustAnotherVictim]

What's the torque plate for?

 

[jdub]

What's the torque plate for?

Quote from a tech library:

Lightweight block castings have become very prevalent in our market. Since the overall mass has been reduced, the controlled stresses have become an important factor in the block's integrity. To ensure integrity, we must recreate that stress by using a Torque Plate when boring and honing.

Always begin by torquing your main caps in place to correct specifications. Next, install a torque plate and torque in place using final assembly torque specifications. Also, we recommend using correct length bolts. If they are too long or too short, they may abnormally stress the block. The future will even dictate correctly torquing all external motor mounts and related accessory brackets.

Allow .003" minimum material in the cylinder bore. Remove broken and partially severed material by honing after the boring operation.


Short version: A correctly installed torque plate takes the place of the cylinder head, which "moves" the block into the position it will occupy with the heads installed. This improves accuracy when overboring the cylinders.

Ohhh...
That makes sense.
Thanks jdub
