Message composed and structured manuals I've come across. The EM section is pretty decent and I would only make a few alterations to the order and add a number of additional work check steps.

On this, I'm working with another fellow to construct a video documentary of a complete engine build. We've already shot all of the video for the bottom end, which details a step-by-step procedure I use in building these motors, including redundant checks on previous steps along the way and additional processes and tricks not mentioned in the book. It will likely be something of value to you if you are serious about building one of these motors.

My first TT engine I built was originally an NA motor I tore down to pieces, went through the parts fishe with the local Nissan dealer's part dept manager who I had befriended, found all of the different parts between the NA and TT motor, and built the NA motor with all of the TT parts. One of the first documented conversions done this way. And I did it all by the FSM. I also sheared several rod bolts in the process as the FSM I had specified 43-48ftlbs for the cap nuts and that was a misprint - supposed to be 28-32. So lookout for this. :)

That was the first automotive engine I had ever built. That car put down 411RWHP and held the record for stock turbos for some time. :)

I had built countless numbers of 2-stroke moto-x engines before that, model airplane engines, lawnmower engines, chainsaws, etc etc, but the biggest difference is that you've got 6 cylinders to deal with. 6 pistons, 12 compression rings, 12 pin locks, 12 rod cap bolts/nuts, 12 rod bearings, 12 main bearings, 8 main girdle bolts, 20 camshaft caps that MUST go back into the identical position and orientation, 40 cam cap bolts, etc etc.. and the part count starts messing with your memory as you will have difficulty remembering every single part's installation as they tend to run together in memory. So you have to take everything in steps with triple checks spread apart over the entire build.

Cleaning is critical and certain steps must be taken to ensure that no debris is in the critical areas.

Laying all of your parts out in an organized fashion according to the process flow as well as organizing the tools required for a particular step is key to process.

Absolutely do not try to build a motor with your buddies or any audience - you will screw up. Its a one-on-one with the VG. Cool quiet environment, no cell phone, no visitors.

The level of experience with precision mechanical systems/components/tools, attention to detail and ability to identify flaws in parts all plays into a successful build and in all honesty I would not recommend any novice or moderately experience "wrench turner" to build one of these motors. These are precision machines with lots of parts both big and small that ALL must be defect free and installed properly. There are a number of basic engine building processes that are shared when building any engine but there are also some particulars with each of them. Knowing those that are specific to these engines will make a big difference in the success of your build. Steps and tricks that are not mentioned in the FSM along with the step by step video to show the process is something I think every car owner should have for their toys. :)

Will be shooting the video for assembling the heads soon to complete the second phase of the video and then following to the third phase for longblock assembly and final assembly to installation state.

Not trying to throw a sales pitch here, LOL. Just letting you know what is coming down the pipeline soon. In the meantime I would suggest studying the FSM, EM Section, beginning to end. IF you have a dead motor laying around, put it on the stand, take it completely apart, and then reassemble it to the specs in the book. :) Do that a few times in your spare time - remember you have to take it COMPLETELY apart. PArt of the process is simply dealing with the part count itself. :)
