Nissan KA swap For 1st gen.
Hi there all. I already know I'm going to get the "zomgz Ur not KeepIng Ir 7 a Rotary? WTFBBQPIZZA" from alot of people. Well basically I'm buying another 7, and I want to use my first one as a drift project. I read somewhere on here a long time ago about someone having a kit to do this swap. Does anyone have a link or anything? I just want the ka because it has gobs of torque, ample power, and a little more aftermarket support vs. the 12a. Any Help would be greatly appreciated. Thhanks!

You want your first gen rx-7 to be powered by a single or dual cam truck engine that can't hold drifts because it runs out of breath at 5500 rpms? Go with an SR or a 1.8L Miata engine if you want a recipro engine so bad.
Where do you see this "ample" aftermarket support? Most properly built KA engines have a lot of money put into them, and people keep them for class restrictions if they actually compete.
Most of the good parts are discontinued and the rest is made by cheap junk or is custom fabricated (quality time)
If you still think this is a good idea, please swap your brain first.

Wow to the douche bag above me. Hmm let's see, I don't have the money to dump into an sr, and as for the miata motor, I've looked, there are none in my area. I want to build a cheap drift project, not dump 10 of thousands of dollars into something I'm more than likely going to wreck. If your going to be such a ******* *****, keep your elitist comments to yourself, or just keep your mouth shut period.

I don't care if you think i am an ******* or not. I am telling you the truth. There is a reason why most 240SX owners don't want the KA's in their cars. It was never built as a performance engine in the first place.
If you want so much help with your KA Swap go to a Nissan forum and see how much support you get....or better yet...go to a Nissan Frontier/Hardbody forum. They build their KA's for performance because that is the engine they got in their vehicles and what the engine was designed as (a truck engine). They know how to fabricate parts for the KA, do strokers, turbo kits, and all the goodies right. That is probably the way you need to go because a stock KA24 dual cam puts out a WHOPPING 110 whp.
No one said playing with cars was cheap. If you want to fabricate, and build a KA for performance, by all means do it. It's not going to be cheap unless you want to build it with Megan Racing, OBX, and cheap knockoff parts. In that case, you don't need to crash it for it to fall apart.

If you didnt buy the car yet, and you want a drift car, why not get something else that requires less work and less time to go out there and do what you want right away?
If you want a KA, why not just get a 240?
If you want a 7 but dont want the rotary, do it once and do it right, and get the SR like the others said.
You're gonna be saving pennies if you go the KA route.
Might as well make it worth it. If you dont have the funds for an SR, then you shouldnt be doing this drift car project to begin with.
You have to pay to play. Thats like wanting to get laid from a stripper but not bringing any money.

I was talking about a stock one. In stock form they have a bit of peppy torque, enough horses to make it somewhat move a little. They dyno about 110~ whp in stock twin cam form as i have seen.
With enough money, and the right/quality parts...you can make any engine do what you want it to do reliably. I have seen plenty of build KA-T's perform incredibly (450-550 whp). They were built on larger budgets, and built right to make power (turbo, custom manifold, headwork, pistons, rods, prepping the crank, standalone etc)
Considering that 10,000 is a lot of money for this guys's "drift car", it will probably take him that much, and time to first source the engine, then inspect it and maybe overhaul it if needed....drop it in and THEN modify it to make power, and extra revs. Since it was not a turbo motor in the first place, A LOT has to be done to do it right. He is better off turbocharging his 12A and building a nice carburated turbo engine...or, swapping in a reciprocal engine that is already at a high potential in the first place.

You know, I kind of agree, I just figured it'd be cheap because my friend has a freshly rebuilt KA in his garage, tranny, ecu, and wiring harness he'd sell me for 500. But, if it's as much work as you say I'd be better off picking up a 13b. I didn't mean to be such a dick, but you came off as one of those elitist ******, and I'm just not cool with that. So my apologies. That being said...does anyone Have a pair of illuminas for the front of a 79, and an LCA?

^ You should go to some of the Nissan Frontier forums, and Nissan 240 forums (Freshalloy is a good one) and peek around (if you already have not). See what it takes to properly build/with quality parts... a KA24 Dual cam to your desired power levels.
Not saying you should take what i say literally, but if you prepare for the worst (which is what i stated above)...then you are always better off in the end.
In the end, regardless of what power levels you are at and what engine you have.....if you really want to enjoy driving the car, then you need to beef up everything around it (caging the chassis as it's old as hell, good adjustable coilover suspension, brakes, bushings, alignment parts, etc). If the project has an open timeline and if you can take your time / money to build it right then no problem. But if it needs to run ASAP, you need funds allocated for that (chassis prep and other stuff), and restoration/repairs too.

^^^ dont be stupid, i live in south dakota and can get ANY part for an SR (besides rare aftermarket) in less than a week. Most autopart stores dont even carry parts for the ka motor and you have to wait atleast 2 days for them to ship them in usually.
Just because it was made in the USA doesnt make it easier to get.

A strongly rebuilt KA done properly will cost your right in the ball park of 3 grand (the cost of an SR swap.)
