The great engine build project begins
Well, it is official. The project is off and running. I go from being really excited, to asking myself what the heck am I getting into.
I was searching for a high mileage 993, when I came across an engine, so I figured I would build the engine, and then find a car. I found a car shortly thereafter, and decided I would still like the engine as a project.
The plan was/is to rebuild an engine out of a 97, and put it in my 95. The new engine will have RS intakes valves, RS cams, and of course varioram.
I probably would not have attempted this if it were not for this great site and Mike J's site pcarworkshop.
I know most of this has been covered either by Mike's rebuild, or JMarch's varioram transplant in a 95, so mine will be a little of both. I will try and keep it simple, yet informative. Maybe it will inspire someone else, or maybe it will allow someone to point out what I am doing wrong.
I started with a long block and boxes of parts, so I have quite the learning curve. Let me know if there are more photos of something particular you would like to see, and I will try and add them. Enough chatter.... let's begin.
I removed the heads and P&C's, and then removed the rods and sent them to Steve Weiner. Steve examined the bearings, and advised that he would not split the case. I had him redo the rods and add ARP bolts. He sent them to me rebuilt with the bolts installed and instructions on torque.
I then sent him my heads and had him rebuild them and after lengthy discussions, he added RS intake valves. They are pretty. He sent them back along with a set of RS cams he had. I do not believe there is anyone more knowledgeable or friendlier than Steve and feel we are lucky to have him as part of our community. I also have been thankful for the great service and help from the guys at FDMotorsports.
I have now started putting it back together, so here are a few photos.

Nice project. Should be well worth the effort when you get in for the first drive.
Will be watching this thread when you update.

Atta boy Emerald, keep it going! If you have questions, you can post here but the best spot to play when it gets really technical is the Pelican rebuilding engine site...lots of good info.
If you did not split the case, and replaced the rod bolts, you must of used the torque method to tighten the rod bolts, rather than a stretch gauge? Nothing wrong with that, but I am just interesting in knowing.
Do you have the timing specifications for the RS cams? I am curious on the lift TDC, what is it? I assume you will use a mechanical lifter for this measurement? ( I found I used a few used mechanical lifters, but I had to grind the sides given the cam carrier design is a bit different).
Did you have any problems putting in the rings? You got the orientation right, correct?(gap on the oil ring to the top of the barrel). The rings will rotate anyways, but its good to get that right from the beginning.
A spot that is really crucial is the cam timing, especially with the RS cams. Are you going to check the clearance between the valves and the pistons?
Anyways, be carefull, go slow, and it should work all out....like I said the more nerve wracking part is the startup....LOL!
Cheers,
Mike

Thanks for all the support. I am sure there will be times that will be more fun than others. It sure gives me an appreciation for Mike and Joe's projects, and the detail they had in there write ups.
Mike, you are correct about the rods. Steve sent them back with instructions to apply ARP lube on the threads, and then torque them to 37 ft/lbs.
The rings were not much of a problem, more tedious than technical. I followed the directions, and made sure about orientation. I have been going real slow, and double checking myself.
I do not have the timing specs for the RS cams yet. I will be glad to share when I get them. Right now, the most daunting aspect is the cam installations and then timing. I have a set of mechanical lifters for this.
I have not checked clearance of pistons and valves, is this something you would recommend?
Thanks,
Emerald

I've been over to Emeralds to watch the build. It is coming along nicely. I can't wait to see how it feels from the passenger's seat. Keep us abreast of the build.
