I think it's heavier, no?

 

Ls1's dont weigh anymore then a 13b (maybe 20lbs, you can leave out 2 gallons of gas if thats a big weght concern)
Ls2's are a hair lighter
Ls6's are around 50lbs heavier...

Why bother going with something thatll be tricky to get running and maintain with limited support when you can get a motor that puts down solid numbers with a really cheap after market and every mechanic under the sun can work on it.

 

go for it

 

its like a 9k swap :[ but ILOVE LSX MOTORS into anything... LOL so i heard even an ls1 in a 240 with t56 all stock no governers, no limiters could hit 200mph

 

its a grate swap... seen it done in pleanty of car 350z 240sx rx7 even a 328i bmw there all rockits the mount kits are cheap its all on what ls u want? like car-berated or fuel injected... seen them all... they are monsters and just think like this YOU star the key and u have 500 hp off the rip no turbo lag no spooling nothing just a turn of the key and its there... hole thing should cost 9k witha shell of your choice my boy did it on his e36 4door m3 and i cant stop beating the **** out of it its just all there but be has a 05 zo6 motor i think with a100shot and othere thing but hope u can wire cuz he said he couldnt find a harness for it but he mad something from scratch not 2 hard but takes some time but thats a beemer... just tune it and put an A1000 fuel pump 2 be safe... but i would say go for this all day

 

heavier the a rotary yeas but like an RB no and a sr20 no the block is aluminum its nothing... just be sure your tranny and the rearend gearing mach up... like u can get a long tranny gears and a long rear and the car will go no where till top end... now not 100% sure if i worded that right but u have 2 gear it right or it will be a dog...

this was going2 be my same build for road racing

Or you could buy a camaro? Or would a vette be more your thing? Think of the time and money you'd save?


People regularly spend $10k to hack a LS v8 into a car. Why? Spend half that money to get the same HP on the FD's REW as a LS has out of the box. Reliable? The rotary's lack of reliability comes from the lack of knowledge on tuning/building/maintenance.

People are just flocking to the bandwagon on this, I don't understand the point of doing a full drivetrain conversion, when the stock drivetrain can be made just as capable for less. Use to think people did it to be different, but now its normal...

 

Well Iono if it's the same as a fd, but I know that fc's stock steering angle isn't the greatest and to get crazy angle would involve alot of modification/ custom fabrication if your really trying to drift it... Also in regards to the oil pan, the clearance possibly may be an issue which may need you to use a dry sump if necessary, which would be beneficial for especially drifting anyways. Honestly posting in this forum, you won't get that specific feedback, just merely hear say/incorrect info, u should hit up specific rx7 forums, ls forums, and real drifting forums to get more detailed and experienced feedback

 

Was just in a RHD FD3S with a Ls6 swap drift car, it's ****ing great. Car still has great balance as well, 1/4 of the money into an ls motor will blow the rotary out of the water why is that even a thought? Car with just I/h/e/cam+tune is putting out 510/505wtq and is basically a 100% stock motor never opened motor. It doesn't cost 10k for the swap tho i'd say more 6-7 you can sell the rotary and recoup alot of the costs.

Last I checked the going rate of 3 rotor 20b is close to the price of the whole swap said and done. 5k~ for motor if you find a good one that doesn't need a huge refresh.

 

Where you getting your numbers from?

Pulling them out of your *** isn't the most convincing source. lol

 

in my opinion its a horrible idea, the rotary will do just fine built properly and for all the extrat work it is to put an ls2 in, itll be cheaper, that just my 2 cents its your car build it how you want

 

Beast!!.LS powered rx-7 build is something id like to do eventully.

 

LS2's are Sick!!! Do it!!

 

i totally agree i think a well tuned 20b will perform very well....

but i cannot disagree lsx series engines' torque is an amazing thing!


heres a video

I was gonna do a LQ9 S14 then I found a 2jzgte FD rx7 and sold my s14 and bought the Rex. Love it!!! Makes 500whp on pump haha!

Both ls/lq and 2jz swaps are common and a few companies makes parts to make the conversion easy. My 2jz fits in my Rx7 like it came from the factory, minus a ugly radiator support bracket and the fuse boxes in my opinion could have been positioned better but Im cleaning all that up anyways...

 

What does your average LS6 I/H/E + Cams + headwork and tune make according to you? 12rwhp?

If you're complaining about my 2 rotor prices maybe they are different here in Canada but we have ****ing boat loads FD3S and FC3S and 20Bs all over the place so what is that you don't agree with?

What's your price on a 3 rotor? Because for 5k you have yourself a 7.0L stroked LS6 making boat loads more than 3 rotor. Hell you can buy one an LSx out of GM's performance catalog with a 4 year warranty for a 1/3 of the price of a 3 rotor. You can buy full LQ9's for 1-1,5k all day too if you're a on a budget (my buddy picked one up for 700 for a local scrap yard)

 

Heres my 2cents on all this. Its your car, its your imagination, its your money. No one should "tell" you how to build your car. LS2, 2j, SR, 20b....A car/motor combo is just a car/motor combo. They have all been thought of, or done already. Build your car to your liking man.

but, since you asked for opinions...
FD rx7s are just...shmexy. Why not make that awesome shell of a platform more badass with a badass motor? Since its going to be multi-purpose, why not build something with power, but not anything too retarded... Like the rwd evo mentioned above. Nothing like putting 10k into a car, and having to buy tires after every time you drive it? (figure of speech, not literal). Me being a Nissan guy, I have never seen a mild built S14 SR20det with VVT in a rx7. Speaking of that, ive never seen a S14 SR20 in anything, besides the S14 silvias they came in...o.0... anyways, I personally think that would be a rather unique build. Costing a bit less than your LS2 idea, and possibly making the same power, depending on how you build the motor, Maybe more. I already know im going to take a rash of **** for my suggestion, but, youll have that. People like different things. Me personally, love the rx7, but am not a huge fan of the rotaries...

Hell, since this is a "honda" forum.....F20C swap that ****!

/end rant.

 

For a 427ci LS6, $5k will only buy you the shortblock.

 

I call bullshit.

 

Find yourself a 351 clevland out of a 71 to 73 stang toss it in there and hang on. You will get whip lash out of those things. But like he said its your car biuld it the way you want.

 

NAAAWW! keep it jdm

 

Go for it

 

id say go for it, that video of the rx7 rapin around the roadcourse passin everything in sight made a believer outta my black ***!!!!!

 

im stil shittin myself bout that

check that site out, they seem to have a pretty good idea of what's going on. I thought about the RX7 LS1 Route. the LS1 only add's 150 pounds so not a big deal with 3 times the torque of the 13b, 3 rotor would be a decent idea, but LS1 is better, and a 2JZ in an RX7 is stupid, 2JZ isn't near as driveable with high HP as the LS1 would be. power band on the LS1 is alot better, and hinson makes turbo kits for an LSX FD's. I'd do it if you had the budget to back it for sure!
