Jalj47 Posted May 1, 2018 Report Share Posted May 1, 2018 I’m in the process of swapping my 73 620 with a s13 SR20, someone is trying to selling me a swap kit from CXracing for a 510 and I was just wondering if the transmission and engine mounts would also fit the 620. 1 Quote Link to comment
flatcat19 Posted May 1, 2018 Report Share Posted May 1, 2018 Won't fit. 510 mounts bilt to that xmember they're trying to sell. 620 has the mount provisions on the frame. Quote Link to comment
Jalj47 Posted May 1, 2018 Author Report Share Posted May 1, 2018 What’s the best way to go about it, I’m stuck and I don’t know where to go from here. Quote Link to comment
flatcat19 Posted May 1, 2018 Report Share Posted May 1, 2018 You will need to fab metal mounts from motor to the rubber 620 mounts. There is an old issue of Project Car Magazine that swapped an SR in to a 620. NA motor though. You could try searching for archives of that. There is a member here(Redeye) that sells KA to 620 mounts. That is if you haven't already purchased the SR... That's just some places to start. You will need to be resourceful with a project like this. Get to it. 2 Quote Link to comment
]2eDeYe Posted May 1, 2018 Report Share Posted May 1, 2018 I make mounts that allow you to essentially bolt that SR into the 620. You still have to deal with the steering and the alternator needs to be moved to clear the idler arm. 2 Quote Link to comment

paradime Posted May 1, 2018 Report Share Posted May 1, 2018 I built an SR swapped autocross 510, and if I had it to do over again, I'd strongly consider a KA. If you haven't bought an SR, here are very valid reasons for considering a KA24 on a purely functional level, especially in a 620. * Torque, until it comes into boost an SR is a 2.0L mouse. Once it hits boost though, hold on... * Cheeper, obviously depending on your power goals or if you plan on turbo-ing it. In terms of control, there's lots to be said for a flat power curve. * More parts out there new from a Nissan dealer and used at any pick and pull. * Simpler mechanically and electronically. * Oh, and did I mention Torque. Not trying to raze doubts, diss your vision, or confuse the matter, just something to consider. Best of luck on your project. 3 Quote Link to comment

I agree, the KA24e in my 620 is more than enough, torque is an understatement, very fast off the line and can spin my wheels 1-3, I don't even need to down shift from 5th to get around anyone, just put the pedal on the floor and feel your body get pulled back into the seat, hell ya she's plenty :thumbup: 2 Quote Link to comment
Jalj47 Posted May 3, 2018 Author Report Share Posted May 3, 2018 I already bought the sr20, where I live the KA was impossible to find. 1 Quote Link to comment

MantisX620 Posted May 3, 2018 Report Share Posted May 3, 2018 With a T25 turbo, lightly grazing the gas pedal should build 45psi in 1st gear. I feel your pain Jalj47, I gave up on finding a KA where I live as well. SR20 it is! MantisX Quote Link to comment
paradime Posted May 3, 2018 Report Share Posted May 3, 2018 Come on guys, the KA was imported into the States in huge numbers, and you can still get parts from a Nissan dealer. KA24e is in 1998-2005 Nissan xterra 1989–1990 Nissan 240sx1990–1997 D21 Truck ("Hardbody")1990-1995 Pathfinder KA24DE is in 2000-2004 Xterra1991-1998 240SX 2001-2004 Forester KA24DE-A Nissan Altima 1993-1999 Don't get me wrong though, the SR is a serious hunk of kick ass, when it hits boost. Just say'n for the money and torque, KA all the way. 1 Quote Link to comment

paradime Posted May 3, 2018 Report Share Posted May 3, 2018 1998-2008 Nissan Navara/Frontier (D22) Japan. Being imported for as little as $800 1 Quote Link to comment
flatcat19 Posted May 3, 2018 Report Share Posted May 3, 2018 You can buy a while hardbody/frontier fairly cheap. Don't matter. SR was bought...for the price of 3 hardbody pickups. Quote Link to comment
]2eDeYe Posted May 3, 2018 Report Share Posted May 3, 2018 has about the crossmember for the transmission? If you read through the KA swap thread it shows pictures of slotting the mount. http://community.ratsun.net/topic/39780-620-ka24-motor-mount-brackets/ The SR swap and KA swap are essentially the same other than the SR alternator hitting the idler arm for the steering, that will need to be relocated. You can use the alt bracket from a G20 to move it to the power steering pump location. BEEBANI, a member here sells a slotted tube crossmember for mounting pretty much any transmission into a 620, if you wanted to go that route. 2 Quote Link to comment
hosestop@msn.com Posted May 3, 2018 Report Share Posted May 3, 2018 Sorry but most Ka24 out there probably need a rebuild after all the drifter boys beat them or TRUCK MOTORS ARE VERY different Blocks starter cams intake I am not going there again ! . Regarding SR20s I prefer because there supposed low miles and run really smooth and get way better mileage than a KA and really our cars are old and most people drive on weekends and don't use for work and believe me the SR20de NA in the last 510 ran strong ,So consider SR20de NA for a reasonable conversion smooth and dependable ,now where do get parts ? Feel free to ask questions S14na 1400 bucks here in LA/Oc areas. 1 Quote Link to comment
hosestop@msn.com Posted May 3, 2018 Report Share Posted May 3, 2018 620 or 521 Also something to consider is that Ka or SR trans are stuck under cab on top of xmember for torsion bars so must remove motor and trans for a clutch job , I recently made tunnel removable remove seat to pull trans tail into cabin to allow clutch service , so there is a lot of pros and cons either way just my snags ect . Not easy 1 SR20 NA while available last made 2002 s15na is what these are . 2 Quote Link to comment
2wheel-lee Posted May 3, 2018 Report Share Posted May 3, 2018 I hate to sound like a d!ck, but I can't help but think if he needed to post here to get commonly available information (Google), the rest of the install is going to be a huge problem. I foresee another 620 chassis and SR20 being parted out in Bakersfield in the coming future. There's certainly no shortage of these "packages" for sale on facebook and craigslist. I think people don't do enough research or overestimating their abilities before jumping in. And those who do manage to actually get them running, so many I've seen are total hack jobs and sold for various reasons with text something like "runs great but needs tuning" or "extra block included." 1 Quote Link to comment

KoHeartsGPA Posted May 3, 2018 Report Share Posted May 3, 2018 Nice. Looks like I should move crossmember design up on my list of things to do. How far back did the holes move? About the same distance as if I were to slot it (I believe) I don't recall the exact distance....I'll have to measure next time I'm underneath to give you an accurate #, the nice thing about this setup is that I can remove both (the mount and cross member) by unbolting. Would be awesome if you can recreate a mount, definitely! 1 Quote Link to comment
