what are you trying to accomplish with this Jeff? wouldn't it have been easier to do as you originally attempted by adding some metal to the blacktop combustion chamber and reshaping it to add more quench then to attempt to reconstruct the intake ports? It is more ideal to have smaller combustion c...

Bingo.

Good point with the digitization. Digitizing a cylinder head is a bit more difficult, but this should be a breeze.

Holy mackerel! Wow. So much attention to detail. What car are you developing these engines for? http://i170.photobucket.com/albums/u279/killer_siller/toad/img_5163.jpg Right now it's a stock AE111 engine with AE101 throttles, as AE111 throttles are a bit on the big side for this application and I p...

Thank you very much! I took some time and started into a blacktop head as well. This one isn't as far along. You can see it's not quite symmetric yet, but that's the beauty of doing this with plasticine first. As of right now I'm happier with how the blacktop port looks than the silvertop. It was ea...

I spent time today with plasticine, shaping tools, and an untouched silvertop head. I'm starting with an untouched port. Next I'll open up a different port on the head and make changes such as the desperately needed short-side-radius, bowl, and valve-guide boss work. I'll then build up that port wit...

Aaaaand here's the difference between AE101 and AE111 intake ports! https://lh5.googleusercontent.com/-KtVfYHMylBg/UORLwnd6bgI/AAAAAAAAAOU/O5ofuU8q1nc/s800/IMG_4522.JPG https://lh5.googleusercontent.com/-DG7_Ts7PSK8/UORLw6QBmeI/AAAAAAAAAOY/KaCTJR2MJig/s800/IMG_4524.JPG https://lh5.googleusercontent....

It's hard to tell, but this is an AE111 head. So we will have molds of both 20v heads! https://lh4.googleusercontent.com/-MnBnyrK9yQI/UOGzdeN9DXI/AAAAAAAAAM0/Qq-7VBO6XHI/s800/IMG_4516.JPG I found the valves I'd used for doing valve testing. The numbers I came up with as being most ideal are VERY sim...

I ordered up some port epoxy. I'll be taking a go at modifying AE101 ports to more closely resemble AE111 ports. This should also give me some practice before I go and epoxy on tho FSAE cylinder head. I'll also be talking to a local shop about my AE111 head and we'll see what can be done with replac...

I finally openned up my cams. I got a set of their 20v PonCams for this engine. Tomei has the best timing cards I've ever seen. https://lh4.googleusercontent.com/-38AOAzw3u3Y/UMyjOv9RdoI/AAAAAAAAAIs/Tczjea_M0vg/s800/scan.jpg Cams then went into the head to map their profile. I usually have a nice se...

I was not happy with the roundness of the main bores on the block I'd deburred, so I went out to the garage and got another one! This one measured out much better and looked to be a substantially better casting. So much better, in fact, that I'm not going to bother deburring it. Anyway, I measured t...

Next I assembled the mains with ARP studs and Tomei ladder bars. https://lh3.googleusercontent.com/-8C_qCJAjwRE/UNC8_cwRglI/AAAAAAAAAJo/cKgYythDgWE/s800/IMG_4481.JPG Block didn't come out to shabby. Before I got these all torqued down I realized I missed the washer on the right on main #5. This bloc...

After I was done with the office work I took the AE111 block out to the driveway to give it ithe TechnoSquare treatment. https://lh3.googleusercontent.com/-ic-xLK_nIqA/UMvPq1rI7HI/AAAAAAAAAIM/PhMeVsUu0nA/s800/IMG_4472.JPG All of the casting flash and all of the rough parts of the casting in the cran...

I have a month or so off betweeen semesters at engineering school and thought I'd finally put some effort into a 4A-G of my own. I've been sharing it on some 4A-G communities looking for some feedback and encouragement. Please, let me know what you think! The build started the day I got home from a ...
