Tha would be a good run. But godzilla, you should run it at 10psi of boost and not full boost to make it even or else what's the point if your engine puts out twice the hp. Sinc RC's is stock at 385hp...

My engine is completely stock. The only real power adder I have is an AEM EMS that is running the base MAP. I think stock skylines running the EMS made about 280awhp @ 8psi. But then again, that car probably had engine driven fans, smaller intercooler, a/c, and larger losses through the tranny.
I was planning on probably upping the boost to at least 10...maybe a little more. I seriously doubt that I'll be at 350whp on 10psi.
Depending on how we do this, my guess is it'll all come down to who has better traction. Either way, should be a lot of fun.
I'm waiting on my over fenders to come in and be installed...I was told it would be about a month to have all my body work done.
What size/type of tires are you running?

I have a 89 240 hatchback with a 350hp 350 and its really fun except i top out at 60mph due to the hi rear end gears. It wasn't that hard to put it in. How ever i lost all cornering and i had to get bigger struts and i have to make custom headers due to the fact that theres not a lot of room in the engine compartment for now i have the pipes running forward, down, and then back. Glad to see someone is as crazy as i am. hope it works out and have fun.
OK, I guess I have to step in to EDUCATE all u nubs about this "SR is the $hit man! F the V8!"
*Rolls up sleeves*
1.) The first lesson (and easiest): www.HINSONSUPERCARS.COM. Go there, read, understand, and realize why I am saving up for an LSx swap.
2.) A stock LSx motor is 126lbs lighter than a stock KA24DE.
KA24 w/ 5 spd = 596lbs
LS1 w/ T56 6 spd tranny = 470 lbs
For all you nubs, that means the swap will make the entire car lighter and go FASTER.
3.) An LS1 w/ a larger aftermarket under pully (the crank pully) once dialed in correctly pushes out 298 rwhp (this number came out of my buddies FC RX-7 after we got it dialed in and ran it on the dyno)
4.) Brian Hinson's FD RX-7 specs are as follows:
'93 FD3S
'01 LS1 / T56 (6spd tranny) combo
Stock heads / medium cams
Factory Exhaust manifolds
Underdrive pully, Ported Throttle Body
Approx. 110 HP Dry Shot NO2
Est. 375 RWHP NA (without NO2)
Actual time on 1/4 mile w/ 5500 RPM launch = 6.71 sec
*check out the video Brian has on his website*
5.) Brian has been building LSx powered RX-7 for years successfully, now he has built two (2) fully functional LSx powered 240's. One of which was in Formula D series this year (unfortunately... the driver kissed the rear and the wall at the end of the season.)
6.) Brian has told me flat out, if you cant afford the custom parts he has already manufactured, he will tell you how to do it for a cheaper price. Which means, if you cant buy what he sells, he will tell you how to make something that is just as good and reliable if you have the resources to do it.
7.) Doing an RB swap or a 2JZ swap will ADD unnecessary weight to the car. The 2J and RB25 will add approx. 70lbs more to the current weight of the 240's front end. The RB26 will add slightly more, but not by much. So what does that mean? You will have more difficulties turning and performing weight transfers due to the added weight. Why not get a bigger power plant dropped in for cheaper and lose well over 100 lbs at the same time?
8.) For all you sav motor sport guys, for every 10 lbs u take out of the car, you gain more out of the car than trying to make one more hp out of the motor. In circuit racing, every 10 lbs you lose will take off approx. a tenth of a second per lap. Now looking at that aspect, you just lost 130 lbs just by dropping in an LSx w/ a 6 spd, do I really have to explain this one?
9.) Those small block 350s on cruising speeds have proven to yeild almost 30 MPG in Corevettes, which are heavier machines than our 240's. Brian has proven that an FD can get an average 25 mpg with an LS1 swap. The LS2 has been proven by GM to give a better gas mileage over the LS1.
10.) Money, yes, for 5K (including the motor), you can drop a stock SR into any 240. But a stock SR only produces 220 hp (Black top) for the most ppl who spend the money for the black top. And that 220 is at the crank, not the wheels. But for me, I will save up the extra $ and build a beast.
11.) Aftermarket support, all motors mentioned have a strong aftermarket support network that is unrivaled. But all JDM markets sell parts that cost $. My AFC from Apexi cost me 300 bux and that was just an AFC. For an SR to match the stock power of an LS2, you would need to change head gasket (to handle added boost) most likely cams, rocker arm stoppers, fuel pump and rail and of course, a bigger turbo. How much will that cost to drop 350 hp at the wheels? Lets see, I would say including labor, over 3000? Yeah, for the same amount of $, Id buy the LSx and spend a couple grand more to lay out 400+ to the ground and still get 28 mpg on the highway. Try getting the SR to drop 400+ rwhp and still produce 28 mpg... not likely.
Dont get me wrong, Im a fan of the SR, RB and 2J. Hell, I can get a 2J mounting kit for 1500 from Tech2 (2JZswap.com). On top of which, our RB26 swap in our S13 (Team Falken Motorsport Dynamics Gold car) has done nothing but make me wet my pants. On top of which, our first Formula D car was powered by an SR. I just personnaly think from experience that the numbers make more sense and since I live in CA, the only two legal swaps I can do are the LSx or a USDM 2JZ (which are very hard to find for a decent price) so why not go with what works best for me?
It is still your own option to choose which motor to drop in your cars engine bay, just dont go bashing other people cause they think outside of your box. Personally all this crap from other people bashing others ideas is pissing me off. Especially most of them who dont know what their talking about. Like the moderators have said, our culture (car tuning, domestic and import) is based on not only improving the car you have but also for the guys who want more, the culture is based on innovation and creation. And proof of that is also in a certain Mustang that made it into the 3rd installation of a certain car movie... think RB26 with a fat turbo.
Side note, all of you who think the VK45 and VK56 are good swaps, yes they are, but where are you going to find the manual tranny for em? Oh yeh, adapter plate and use the 2J 6 spd tranny. Oh wait, but you have to find someone who will put up with the mad stress of figuring out the wire harness since it was never done before. Oh Oh, and all the mounts, custom fabrication there, OH and what stand alone system will you run since no one has made one for sale yet?... Either VK swap will run you well over 10K not including price of the motor, dont forget that the VK56 wont fit without cutting a hole in the hood. Look at my teammates car, Chris Forsberg's VK56 powered 350 convertible, I dont remember what tranny he runs, but it sure as hell aint the tranny from the titan. BTW, the VK56 is the same block as the Triton F-150 5.6. Still, the guys working on Chris' ride still havent figured out how to manage the system correctly, but it sounds like a BMF'er from hell though... Jus wish the damn thing would run right for once.
*edit*
To the moderators, sorry for the flamming, but someone has to step up and tell the unexperienced kids who claim to be experts at tuning the actual truth about their knowledge (which is very minimal as pointed out by S13 240). To the person who posted this thread up a long long time ago, keep it up and... for God sakes put up some pics and update us dammit! LOL

It is hard to believe, but check out Brian's videos. There should only be one 240 video and it shows flat out how much MORE the KA weighs vs an LS1. And yes, an LS1 powered 240 is faster than an LS1 powered FD. Reason being, the LS1 powered S14 is about a little over 100 lbs lighter than the LS1 FD.
Mildly built LS1 S14 for teh win!

im not sure if this is true but i think it is.
the all aluminium LS1 motor weights less than the stock KA?
330hp in a lighter motor with about the same compression?
Turbo'd LS1 would be worth the trouble of swapping. The deep V8 sound with the even better sound of a turbo spolling, ya i think that would be worth the trouble.
