20b Conversion questions.
Lol! That's not mine! Pic is nearly 9yrs old and courtesy of Alamorotary. Here's the new owner of that engine.

Seriously though, your car now has a shop mate at Kilo and the work on your car looks great. Jesus was running the ac lines yesterday. Mine is in for the methanol injection kit setup and a few other things before DGRR in two weeks.
Speaking of unfinished projects, how's that car coming along bewtew?

Thanks for the pictures by the way. when i called Jesus to tell him that i sent him the pictures he said.. "i'm one step ahead of u, i got David's car in the shop"
.. a Van Gogh, or possibly a Da Vinci ... no no no, its a Debacle... yeah, it's a Debacle
Come on dude! Cut the OP some slack.
Give him some credit for actually getting the conversion up and running. Many DIY dreamers haven't been so fortunate. He has all the time in the world to improve on the fabrication.
- not everybody's got the resources to do exhaust work. I was amazed to see/hear a running product!
No, the meth will be for safety only. It might allow me to run more boost though and if so, yes more power. And I saw Jesus running your lines. They will be very similar to mine I think.

So I know my welding, or fabrication isn't the best, but with what I had at hand it's the best I could do. Now if I had a tubing bender, and a true mig/tig (whatever is best for welding exhaust) welder, and took the time to do the math to make even runners, then I'd have a manifold just as good as the other pictures. Considering I only have the ability to do the math, that's all I could do. If you want to bash my work be my guest. It's still not going to deter me from getting this finished. If anything it's going to make me want to finish it all the more. As for the comment that the car is dangerous, at the moment it is dangerous. That's only because it's not finished. So I don't drive it. When it's finished then it'll be just as safe, if not more so than when it came off the factory assembly line. Thanks for the support from the rest of you though.

Good job on going N/A, when I first read you were going to use one of the twins, I shuddered a bit. Sounds good though, time to get familiar with the Microtech, make sure the motor mounts are welded a little nicer than the exhaust manifold (seriously.) and get it running smoothly. I agree with one of the posts above, it would be a great idea to get a compression test on it to make sure all the seals are intact. Otherwise, you're off to a decent start.
But for the love of god, melt that old manifold down to scrap and never think about it again. LOL

So, I've been playing around with my microtech ltx12, and the new software. Anyways I think I might have screwed up my base map, so I was wondering if there was anyone here that might be able to help, maybe let me know where the settings should be. I started a thread over in the microtech section also. https://www.rx7club.com/showthread.p...7#post10686537

So, it's been a little while since i've had the time or energy to work on the beast. My bigest thing was having issues starting the thing. Which brings me to my latest question that i hope someone can answer for me. would a vacuum leak cause a hard start, and a fouling out of the spark plugs with an after market ecu? I thought that i had pluged all of the many vacuum ports on the manifold, but tonight i decided to take the uim off and clean and put the brake vacuum port into it. Lo and behold when i go to take it off though all of the uim bolts are loose, and there's 3 vacuum ports that aren't plugged, and not connected to anything. So, i have since blocked off those pesky ports, and am now waiting to bring my uim to the shop to clean the inside out of all of the metal shavings from drilling my vacuum port. (sucks not having my own compressor!!!)

oh that looks so clean great job
wow! i don't even know what to say...
Is this your first time welding? if so i recommend you getting help from somebody that knows how to.. Please don't take this the wrong way.
granted we had all the tools to do it and still took us about a week to do.
your attempt to make a manifold looks like you put a bunch of scrap pieces of pipes you had laying around and slapped them together.
this is what a manifold should look like..
