    I sold that car way too cheap. I used the money to buy this used 2019 Tacoma Sr5 (before used cars got stupid expensive) it still has less than 50k miles on it. Most of the fun money I would of spent on the e30 goes to boat gas and tackle/bait. I do get a lot of enjoyment from fishing and boating in general.

ID:	10107854 My wife now drives this truck and I'm driving a 1999 Tacoma with over 300k on it.
    I'm playing around with the idea putting a K24 in it with a TH400, and a ford 8.8 axle. I probably won't though. Everything on the truck works perfect despite the mileage.

    maaaaan what a sad ending. I was very close to buying it from apartment complex kid when he listed it for sale, but had too many projects going at the time so i bailed. It was listed as needing a trans at that point, i think. I thought he sold it, but apparently he sold it to the salvage yard. what a shame. thanks for the update!

    I have a bit of bad news for you guys.

    While working on my pool salt system today I got a random FB messenger message from a complete stranger.
    A guy found my e30 sedan in a junkyard and found an my registration in the glovebox. He then found me on FB. He wanted to know more about the car.

    I sold this car in early 2021. I lost interest in it, even though nothing was really wrong with the car, and it was in it fastest form it ever had been.
    In the last 6 months of ownership I only went on a handful of joyrides to scare the shit out of my friends and relatives. Which, I really did enjoy. Having close to 600ftlbs of torque at 3000 rpm was crazy. The cost of nitrous didn't even bother me. I figured ever 10 seconds of nitrous time cost me about $12.

    I really got into fishing during covid and lost interest in wrenching on cars. Pursuing both hobbies to the level I found acceptable was a financial impossibility. Fishing offshore on a boat is pretty expensive.

    I sold my car to probably the worst possible person I could if sold it to. A young man with no place to wrench on cars (lived in a complex) that had no skills working on cars. He told me he planned to put the interior back in it, which I had removed because the drag strip insisted I weld in a roll cage to continue racing. I was running consecutive 7.0 second 1/8 miles at 100mph. I dipped into the 6.9 once and they freaked out because I wasn't wearing a fire jacket.

    I tried to tell the kid that this car was basically a race car at this point and any attempt to return it to a full interior street car wouldn't be worth the effort.

    The kid messaged me saying that he had to pull the transmission because while attempting to change the transmission oil, he fucked up the fill plug port so bad that a machine shop had to get it out, and he had already emptied out oil from the drain plug.

    He then struggled to get the car in a driving condition after this failed repair. I think he got it back together but couldn't get the clutch to work or something dumb like that.
    I imagine he then ran out of time/money/or the patience of his apartment complex and was forced to get rid of my 10 second, 3.6L, cammed, M30 swapped, beater sauraus.

    I'm glad the guy at the junkyard found me, so that I could explain all the stuff in this junkyard car. Someone I'm sure will end up with my engine in thier car one day. I'm also really glad that I took the time to document all the things I've done to the car on R3V.
    that was the first thing I told the guy. Read my car thread.

    I'm having a lot of fun with just the nitrous. It hits way harder than any turbo car, however it lacks the up top power of a turbo car. I took my car back to the 1/8th a couple weeks ago and pulled off 7.03 second at 99.67mph with a 1.5 60 foot! That is as fast a stock Dodge Hellcat!!!! Second best pass of the night, still not bad. A short video. This pass was only a 7.3. https://m.youtube.com/watch?v=shDFh_KpMUE I'm gonna keep slowly increasing the nitrous till it seems unsafe. I data log every run and adjust the tune as necessary. It would be insane if I could get this thing to run a 6.4 (9second 1/4 mile!) Sent from my SM-G960U using Tapatalk

    Just finished my second nitrous stage. I added an additional dry nozzle before my throttle body This is my first main stage. Currently jetted for 175hp And my second I had to upgrade my line going back under the car and into the trunk to a -6 AN. The -4an can't flow more than 200hp especially with my long run to the trunk. I then Y the main feed right before the 2 solenoids. This line is -4 AN. My setup right now is 175hp right out of the hole. I have it setup to activate at 2800RPM and WOT, but I launch at 4000RPM so it's on immediately when I floor it for launch. Then I have my second stage activate at 3800RPM. It's currently jetted for 100hp but I can increase it to 175hp. I may have to increase the stage 2 on RPMs but it will require fine tuning at the track. Here are my current settings. I haven't tested the system yet because I am on the stock fuel pump, and am afraid I will lean it out with a 275 shot. I'm thinking it will be close to 450-500whp. The goal is to get into the ten second 1/4 mile range. As you can tell, I'm addicted to drag racing. Sent from my SM-G960U using Tapatalk

    Took the car to the local 1/8th mile last night. Ran 3 consecutive 7 second passes. I changed my launch technique and increased the nitrous from 160hp to 175hp. This thing launches so! hard! Sent from my SM-G960U using Tapatalk

    Took only a week to get my machine work done. I had the block bored up 2mm to accept my larger pistons. The engine displacement went from 3430cc to 3581cc by increasing the bore to 94mm. I also had the crankshaft and entire rotating assembly balanced. I was so excited to drive my e30 again I assembled the engine in 1 day. Just to make sure I checked the valve to piston clearance by bolting the head on with an old head gasket and modeling clay on the pistons. I didn't measure the exact amount, but it appeared to be ample. I gapped all my top rings at .023" and second rings at .026". I wanted to make sure the ring gap was large enough for a significant amount of nitrous. I bought a S38B38 head gasket because the bore is now 94mm and the S38B38 is 94.5mm. I slapped everything together and didn't take any pictures. I drove the car all week to work, changed the oil and took it to the drag strip. It did pretty well with only 160hp of nitrous. Time to build a multi stage nitrous system. Sent from my SM-G960U using Tapatalk
