    1970 Nissan Laurel KC30 coupe w/ SR20DET

    Well, I'm at the start of hopefully a long love affair with a 70 Laurel coupe...

    This is it, just bought it yesterday here in Okinawa, Japan. It was a rare thing to come across and I could not pass it up. For a 70's car in Okinawa the body is in very good shape. I got the car from a local tuner/dealer of classic cars, who bought it 3 years ago from mainland (why the body is so good).

    It's a coupe, from the first year they were available, the shop owner says it's the only C30 coupe on the island, and I don't doubt it. It's got 4 spots where rust is on the verge of being in control, but I plan to ship it away from this car eating island in a few months for the old car friendly desert of New Mexico, USA.

    I was originally looking for an old car (expecting it to be beat up) that I'd put an SR20DET into. However when I came across this, it has the original G18 engine running good. So I am really leaning towards keeping it original. I can always change my mind later if the engine dies. Either way it'll be a nice ride.

    Now I'm looking at the uphill battle to find parts. Right now I'm looking for aftermarket parts for the Suspension, Intake and Exhaust.
    I have found that KYB makes shocks for it, which is on the top of the list to get. Now I need to find a company that makes springs and strut tower brace. A friend told me about a company that makes a brake steel braided line/upgrade kit for it, allowing bigger front rotors and rotor conversion for the rear. I think that is something I'm willing to depart from original form. I'll just keep the original parts on hand. I hope to find intake upgrades, but don't know if that's available for the G18, same with exhaust. At least exhaust I can have done custom at any point.

    I've been looking at Eric's 71 C30 he's modifying: viewtopic.php?t=8475
    It's been making me think of the possibilities and options down the road.

    For now I'm getting the paperwork switched over to me, and have to start looking a scheduling a shipment date, etc. Looking into the basic upgrades listed above so I can get whatever parts I'd like that are available here in Japan before I leave. And taking TLC of the body to get it through it's time here and into the desert.

    If anyone knows of any aftermarket companies that make parts for this model and engine, please share your knowledge. Also, if anyone has any experience with the G18 engine and has tips to share, please do.
    I hope to be a long term owner of this beautiful Laurel and member of this forum.

    Thanks for the compliments, I simply fell for this car the moment I saw it. Normally I preferred 4 doors (like the Skyline I had), but the lines on this just caught me. Especially the split windows without a pillar.
    I got this at a pretty good price I think, it was 390,000 Yen. Since I'm going to drive it here for awhile, it'll be a little bit more due to inspection, registration and insurance. Plus it should cost about $1000 (USD) to get it shipped when the time comes. But even with all that, I think it's still a good price.
    I think part of it may be because if the car stays here on island another year, the rust will get out of hand.

    that is a nice car def rare,,,the military wont ship for you back to the states? or are you civillian contractor? anyways if the motor dies you can always put a sr20de and you shouldnt have do much except rotate crossmember or you could go l-series or ca18 just modify pan...lots of options i wouldnt worry about engine choices ..body parts might be a consideration though.....but that is definitly a cool ride....

    Well, I picked up the Laurel a few days ago. It runs, but the carb needs to be rebuilt/tuned. Currently I have a choice, adjust it to where it idles smooth, doesn't stall, but doesn't want to start... or where it starts, but keeps stalling out and running rough. Granted, I'm not used to having a carb. I've got a guy who is and has helped, he's telling me in needs a rebuild.

    Today I found out I can get an S13 drivetrain/suspension for a good deal. I'm craving the SR20DET and have a hard choice... I put up a poll of see what you do if you were in my spot, it's here:
    viewtopic.php?t=10277

    Here are pics of my new love:

    put a weber 32/36 on it and drive it ...you will probably need adapter also...that will solve all driveability problems and will run great..i am reading that you have a month before you leave to switch over to all s13 sr20det running gear might require more time than a month....no that it cant be done ....

    Well, I'm progressing slowly on the registration change. The Laurel doesn't want to cooperate getting through inspection. The initial inspection had several faults... one reverse light out, sticker on the window, front tires protruding from fender, engine oil leak (actually residual fluid), clutch hose touching the body, P-brake cable/exhaust touching, and exhaust leak.
    I repaired things, but the tires, I could only switch front and rear (different sizes) and hope. Try two failed for the front tires protruding again (not even a mm really!) and the clutch slave cylinder that decided to start leaking.
    Now I'm waiting for the overhaul kit on the slave cyl, parts for this are hard to get. The Nissan dealer had to look at the vehicle, because they didn't think I gave them a real serial number. Took them a day to research the parts, and luckily, of the two slave cylinders used, I have the one that has an overhaul kit. 1 week wait due to only being in a warehouse on mainland Japan.
    So, in the meantime, I got a couple more pics:
    Here's the AC compressor! It's huge! About a quarter the size of the engine block!
    The interior again. The AC unit is an under dash model on the passenger side.
    The detailing on the center console.
    Just a dusk pic of the front. Just because I like how it looks.
    A pic of the rear. You can see a couple of the cancerous spots. It'll be good to get it off this island and into the desert where it'll dry out.
    The side badging... someone had put on the 2000GX badges, even though it's actually an 1800.
    The front GX badge.
    I figure if someone went through the trouble of badging it as a 2000GX, then it'll suit it to have an SR20DET and be the GX Nissan intended!
