Stef's 7A-FE Rebuild, up and running since 12/16/07 Options

[hurley97]

So obviously my oil problem is only getting worse, I decided it's finally time to do something about it.

so I went and picked up Defgeph's old 7A...
177,000 miles and was begining to use some oil before he swapped and it sat in the garage for 2 years.
but since I was getting it for free from a friend I decided to pick it up and hope for the best...



so I picked it up Fri (8/24) and the next day it came with me to work (I work at a Toyota dealer) where they unloaded it into the brake lathe room and it stayed hidden for a while. this past Saturday (9/8) me and one of the techs began tearing it apart. I was pleasantly surprised to find that it is actually in incredibly good condition for its age...

I will be spending close to $500 in parts replacing every bearing, seal, gasket, etc that we can think of. What I need from you guys are your suggestions as to what I can do to make this motor a little stronger and better flowing. I'm keeping the stock pistons and considering bigger cams and having the head machined.

We work for about an hour each morning before customers start coming in. Between Sat, Mon, and Tues (today) we have everything pretty much apart (except for the valves since I haven't decided to send them to the machinist with the head or not yet). This is a huge learning process for me and happy to have the oppotunity to do it. I'll add more pics and info so maybe some of you can learn some things too.

hey, this is very interesting for me cuse i am on the same route, how much NA power can u get out of a 7a. Well i really look forward to seeing pics of your progress. Hope all goes well. My two cents, if you have the money send the head of to Extrude Hone, its a process where they push an abrassive material through the entire head (Intake and Exhaust) and it polishes the sharp edges, increases flow and helps for breathing, the process costs $650 for our head, ive called them before to find out. Let me know if you need more info. Good luck

wow... thats an insane price for that. we already did that this morning, took about 20 mins. I'll have pictures soon.

I spoke to a friend of another tech about machining the head and it sounded like all he was going to do was clean it and make it look pretty and charge me $70. its not that dirty, we can clean it at work. if we have the right tools to port match the intake and exhaust we'll do that ourselves too. I can't imagine a 5 angle valve job being too precise either in which case we can probably do that too. we'll see how it goes
