BADime

My bad. Been busy with other projects, but you'll definitely get a laugh out of what was going on. I installed the walbro fuel pump and checked pressure at the feed line after the fuel filter. Awesome pressure and my return line was working. Fired it up. Runs really rough and after a few minutes the manifold was glowing. Then I remember this thing called timing! Got out the trusty timing gun and fired it up and just couldn't get it close enough to the 20 mark. I WAS 1 TOOTH OFF WHEN I INSTALLED THE F@&$ING DISTRIBUTOR! This thing runs like id always hoped and spins tires like crazy. Thanks everyone for all the help. Next is to do a shakedown (basically just drive it for a while) and then get it out to the track.

i tried installing a regulator but it didnt seem to help. I just picked up a fuel pressure testing kit and i'll be messing around with it a little more. Thanks guys!

I had an account here years back when I started this project but I guess since my profile remained idle for so long, it is no longer. Some of you may remember my car, but if not, here we go again! My stepfather surprised me with this 1972 2dr 510 when I was 15 years old as a shell from a junkyard with literally nothing in it. No doors, hood, trunk, anything. It was merely rolling metal. He owned an auto body shop and wanted to pass on his trade and passion of cars, and 510s. First we started gathering the body parts and sanding, and sanding, and sanding, and I remember a lot of sanding (this was about 7 years ago) before we started to assemble the car. Next I was challenged with forming fender flares to the original rear flares and it was the biggest pain in the ass, but I did it. Then it was into the paint booth for a shiny metallic silver finish. I wish I had pictures of how this project started. (maybe it's archived somewhere on here?) We went on to building a motor and putting in together. I originally built it with an L18 and drove it as my first car when I got my license at 16. I drove it daily until i started getting into fixing up other cars and flipping/trading them. Eventually in 2009 I joined the military and was sent overseas for 13 months while this car sat in my garage. My stepfather passed away in march of 2010 in a snowmobile accident, and I keep his eulogy posted on the window of my 510. RIP Fast forward a couple years and here we are. I recently bought a 240sx to teach my wife drifting and as a donor KA for my 510. I started by posting my L18 on craigslist which was promptly purchased by a local dimer who needed it. About 10 days ago I finally pulled the motor and trans out of the 240sx and started cleaning it up. It took me an evening to pull it, and it was sitting in my 510 the next day. I guess you could say I was a little eager to get this going. I followed a couple build threads I found here and on NICOCLUB and it really wasnt too bad. I even had Inline4 come out to help with the wiring (thanks again). Got it all buttoned up, flipped crossmember, brand new driveshaft built from scratch, and fired it up. https://www.facebook.com/photo.php?v=10202700994235670&l=201951282937683414 It had no problem idling but if I gave it more than 1/4 throttle it would cut out and die. I drove it to a close exhaust shop and had the exhaust welded up from the headers back, then drove it back home to assess the cutout situation. I figured it could be a few things; spark plugs/wires (one wire was always problematic), O2 senson (i ripped off the wire during the exhaust manifold install and soldered it back on), or the fuel pump (rated to flow at 105gph or 398lph). New spark plugs, wires, and O2 sensor in hand I started to replace the easy items. Or so I thought. O2 sensor was no problem, spark plug wires were as easy as 12345, and then came the spark plugs. 1,2,3 was tight as fuck and 4... Oh number 4! Snapped my 3/8 socket extension and broke the spark plug off inside the cylinder head. F@#*! So I did what anyone who wasnt trying to rip the head off would do and got out my easy out set. What happens next you probably already saw coming. I tap it in, no prob. Turning it, it bites! Keep turning it, SNAP. Now it's a party! Of course next is pulling the head and taking it to a machine shop and they laugh at me and get it out no problem. Rebuilt it, new gaskets and head bolts and blahblah. Did research on the torque specs for the head bolts and was really being careful to follow the tightening pattern. Still somehow ended up snapping one off in the block (it hadnt even reached 60ft/lbs). At this point i'm just pissed! Luckily after removing the head again I am able to spin the remainder of the bolt out with some tweezers. I go back to the auto parts store and grab another set and try again, this time not trusting my torque wrench as much as my instinct. Put it all back together and fired it up. Runs even worse now but atleast I know the internals are clean. This is where I'm at now. I think whats going on is the stock FPR is being over ran by a 105gph fuel pump. I know I shouldve just ordered the walbro to begin with but i had this one laying around and figured more fuel was better than not enough. I just ordered a walbro as suggested by many other threads and it should be here early next week at the latest. If anyone has any other suggestions, input or experience with this swap let me know. Especially in the socal area, because if this fuel pump change doesnt work I'll probably want to have it towed to a shop who can help me get it running like it did before I pulled it. I'm frustrated but also proud. I'll keep this thread updated as best I can. Thanks for reading!

Got it figured out! Thanks

Anybody have a wiring diagram for where the 510 harness alternator wires go on the KA alt?

Close to SDSU. I built this car when I was 15 and recently pulled the old L18 and sold it and bought a 240sx with a rebuilt motor as a donor. I just got the crossmember modified and the engine bay prepped and painted today. Something is just making me nervous about pulling this well running KA out and not f*cking anything up. It sounds like you may be able to help with wiring? (which I'm terrible at)

Starting my KA swap on the 510 and was wondering if there is anyone local that has experience with this swap and would like to come help out! I would greatly appreciate it. PM me.
