WallRocket Posted November 28, 2017 Report Share Posted November 28, 2017 Well, after my first sr20 into datsun 620...I figured I might as well give it a try again.I have more of a budget, knowledge of the sr into 620, and better skill sets now. With so it's been going very smooth and I am very proud of its out come.So....I picked up a very nice 1972 Datsun 620 with no rust, and running well. I paid quite a bit for it, at $3500. In my own mind...it was worth every penny. I enjoyed driving it for a few months,then the speed bug bite me again. Out comes the l18!1972 Datsun 620.Me putting it to work.=) pulling it my bay at my shop. And...the parts car. =eekSr20det gt30 drift car (parting out and keeping what I want for the datsun) 4 Quote Link to comment

KELMO Posted November 28, 2017 Report Share Posted November 28, 2017 You can use imgur.....when you upload pics from your computer, you can choose from several "sizing" tabs. I usually resize to the "message board" size....if I remember to hit the tab first. 1 Quote Link to comment

WallRocket Posted November 28, 2017 Author Report Share Posted November 28, 2017 First order of business was to fit in the SR20DET. Unfortunately i had to lose the GT3071 turbocharger because..well..it was just too big. Here is what i did to fit the sr20 mounts. I used Datsun 620 rubber mounts, 1/8th inch steel plate, stock sr20det engine brackets. Cut the stock mounts like so, then just made them fit the oem Datsun 620 mounts. The mounts had to set offset as seen in pictures. Then just added bracing on the truck side. 1 Quote Link to comment
WallRocket Posted November 28, 2017 Author Report Share Posted November 28, 2017 And then..the trans mount. I just used the oem Datsun 620 transmission cross member with 1/2inch spacers to the oem sr20det trans mount. It was very efficient and easy. 2 Quote Link to comment
WallRocket Posted November 28, 2017 Author Report Share Posted November 28, 2017 Firewall clearance. I use S15 water neck to loose the coolant lines that run behind the block. The alternator was a problem for awhile. I ended up using Greddy smaller pulleys to clear the alternator to the idler arm. 1 Quote Link to comment
WallRocket Posted November 28, 2017 Author Report Share Posted November 28, 2017 Next I had some fitment issues with a new s15 t28 turbocharger. I had to cut the Megan Racing manifold and clock it toward the engine block (which makes a custom down pipe elbow necessary as well) I also had a problem with the steering shaft, although i think the stock t25 turbo i would not have to notch the steering shaft. Added a brace, I am no welder, but sometimes i do decent. SOME times haha. (I probably never even seen a decent weld haha) S15 turbo clearance (painted gold so no one in my shop uses this turbo, mock up use only) 2 Quote Link to comment
WallRocket Posted November 28, 2017 Author Report Share Posted November 28, 2017 Next up, coolant neck! So far, this has been one of the easiest swaps i have completed. It went in with no trouble what so ever. 3 Quote Link to comment

WallRocket Posted November 29, 2017 Author Report Share Posted November 29, 2017 Refinished the valve cover with the color of the truck (soon to be) 3 stage pearl white, and the engine bay will be that greyish green color. 2 Quote Link to comment
WallRocket Posted November 29, 2017 Author Report Share Posted November 29, 2017 Flipped the center link, just purchased a new center link for a older truck and tapper drilled out the holes (i might actually weld up the hole and then take to a machine shop to cut) Then just welded the 240sx pedal top to the Datsun 620 pedal bottom, and drilled 2 holes in firewall to run the factory Nissan 240sx throttle cable assembly. 2 Quote Link to comment
WallRocket Posted November 29, 2017 Author Report Share Posted November 29, 2017 Inter cooler was pretty simple. I just had this Honda FMIC laying around in the shop. It had 3 12mm bolt size holes on top to bolt it to something, I just drilled the holes out on the Datsun radiator support and called it good. Its very sturdy, and i am happy with it. To help others with this inter cooler, i think its for a Honda, has 3 bolts top and 3 bolts on bottom, inlet is 2.25 and outlet is 2.25. I will get the length and what not later for you guys. Here is one the problems i ran into with doing it my way. 2 Quote Link to comment
