521turbo Posted June 6, 2018 Report Share Posted June 6, 2018 Hi, I just joined the forum when I bought my ‘71 521 pickup. Im a car guy/mechanic/nissan enthusiast. I previously owned a ‘96 200sx with GTi-R Pulsar motor which I regretted selling. I picked up this truck because I always liked the jap mini trucks and Im a nissan fanatic. The idea is to SR swap it ratty style and do body work little by little. So far Im working on it on my spare time until I collect all the parts, tow it to my shop and get r done! Pics coming soon!! 3 Quote Link to comment

521turbo Posted June 6, 2018 Author Report Share Posted June 6, 2018 Thanks bro..I will as soon as I figure out how, lol. I need a pedal box too. If anyone has one laying around or knows anyone that does would be greatly appreciated! The ones on the truck now are chopped up due to the last swap. Looks like they had a v8 in there bc the tunnel was worked on, has dual exhaust, and a Ford 9”. Right now its a roller. 2 Quote Link to comment

521turbo Posted June 7, 2018 Author Report Share Posted June 7, 2018 Ok...she's not preety but here she is.... Cutting out the old welded SB mounts.... Hope you like the pics....more to come as soon as I make more progress :thumbup: 6 Quote Link to comment
521turbo Posted July 7, 2018 Author Report Share Posted July 7, 2018 Finally towed the car to my shop and I have made some progress...I got my sr20 swap in its an s15 motor with 6 speed ?. I dropped in and pulled the motor out a couple times already as I hit some bumps. The truck had the pedal box mashed up as the previous owner had an automatic and chopped off the clutch pedal. The MC hole on the firewall was torched out to fit a ford MC ?. Tunnel was opened up way too much and no room for foot for gas pedal. luckily I bought a pedal box from a forum member and Im cutting and welding the fuck out of this thing to make it right. Here are some pics..... I reindexed it bout 3 notches. These are my Explorer wheels I had laying around..They fit perfect and got some Neo gens I got the sr20 521 mounts from redeye. But since its a 6speed, tranny mount is a little short. I have to modify the tranny mount. I will post some pics as soon as I do. Parking brake bracket has got to go.... wastegate sitting on steering column..... Got these from Jegs. Ford 9" disc upgrade. Rear discs and KYBs Feel free to post comments, opinions, suggestions, critisize, correct my grammer....Im open and dont give a f*** 3 Quote Link to comment
]2eDeYe Posted July 8, 2018 Report Share Posted July 8, 2018 Truck looks good. How short are they for the 6-speed? I can make sure my next run has enough adjustment. 2 Quote Link to comment
Charlie69 Posted July 8, 2018 Report Share Posted July 8, 2018 The bell cramk assembly for the e brake can be completely removed and you can use a 620/720 e brake cable and handle mechanism instead. a little mod work to get ebrake handle bracket to fit 521. I also swapped out the chassis to a 80 720 reg cab short bed chassis. This gave me the removable trans mount and the e brake and also disk brakes. Another benefit was it moved the pitman arm and the idler arm out of the way, also a rag joint steering column. Some down falls are the tank mounts on the right side which I removed and will have to add back the ebrake cable bracket and the hydraulic brake hose bracket that was on the rear tank mount. Check out my 66 520 build for more build mods that might help you in you build. Link below in my signature. 1 1 Quote Link to comment

Charlie69 Posted July 8, 2018 Report Share Posted July 8, 2018 This what I did to my 66 520 frame to get the engine as low and at the proper angle. This also helped with tunnel clearance but I still had to do the tunnel mod. 1 1 Quote Link to comment

I just wanted the L20B automatic sitting like a stock motor. I used the new style trans mount and that raised th tail of the trans about 2". It is not neccesary on the 80 720 chassis as it uses the new style transmount and has a removable trans crossmember. Old truck trans mount with bracket Newer trans mount As far as your tank goes there is kits available that make your carbed tank into a in tank pump fuel injection. 2 Quote Link to comment

Charlie69 Posted July 11, 2018 Report Share Posted July 11, 2018 65 to 72 520 and 521 tanks will fit. There is a 520 tank on ebay been there off and on for months. Many guys are removing the spare tire and installing a fuel cell there between the frame rails and installing the filler neck in the bed. Quote Link to comment
521turbo Posted July 11, 2018 Author Report Share Posted July 11, 2018 I think Im going to go with a fuel cell in stock location. The truck has one mounted in the bed now but its old and got to go. 1 Quote Link to comment
datzenmike Posted July 11, 2018 Report Share Posted July 11, 2018 There's more room behind the differential where the spare would be. A fuel cell would have to be very narrow and long to fit between the frame and the driveshaft. Does anyone in this age carry a spare? On a long trip like to Canby I carry plugs and I have a 12 compressor. More than enough to get me to a garage. The rest of the time I'm 5 miles from home. 1 Quote Link to comment

Yea you're right I measured and there is no room in stock location. I am going to mount behind the diff. Anybody done this? 1 Quote Link to comment

mrbigtanker Posted July 23, 2018 Report Share Posted July 23, 2018 (edited) Where is the intercooler going, it's a very tight fit. I went water to air. Edited July 23, 2018 by mrbigtanker 1 Quote Link to comment
