SR20DET Swap Into FD3S

Dj*BaM|BaM · 11-09-2001, 08:35 AM

I heard somewhere that this is possible...where I cant rememeber. Any info regarding if this is possible is greatly appreciated. I liek to leave my options open and don'get me wrong, I love the rotary engine and everything. I'm just curious.

Also heard about that V8 LS1/LT1 conversion too. Sounds also pretty interesting especially on a slick car liek the rx-7. Just wondering what you guys can make out of this.

SR20DET in an RX-7? Never Heard of it, but that would be pretty fuckin sweet

I think the LS1/LT1 would be a little heavy for the RX-7 and would probably fuck up the weight distribution pretty bad.

Yes, it's possible.. seen couple days ago it has 1000HP +!

Nahh, that's the stupidest idea I've ever heard. Put something else in and save those sweet sweet SR20DET for us guys that want to swap one into a 240sx.

If I need one and they are all gone I'm coming after ya.

Ok G-Forces...it may be a dumb idea, but you have to admit that an RX-7 with an SR20DET would be a pretty sweet ride.

The RX-7 in Turbo mag has a 2JZ supra engine.
Pitty you yanks didn't get the SR20DET engines in your 200SX (oops, 240SX) in the first place. I think its bloody strange how car companies have different set ups for different countries.
Like Australia only get 147kw in their new 200SX's, yet here in NZ and Japan we get 184kw, cool.

I looked at the page. Sure it would have alot of HP, but I still think "putting a 350 in an fc3s is stupid and will fuck everything up"

By the time your all done, you wont be able to drive the car cause u will be flat broke. Also, once you pop a sweet-ass engine in there, you are forgetting that the GB's in Mazda's arent very reliable, and they dont last all that long, especially with that kinda power behind it. Ud get maybe 6months [if ur easy on it] out of a GB with one of those big engines powering it, after that you better get some pliers, cause ur gonna be pulling chunks of tranny out of your ass. If you run it hard, you can consider a rebuild much sooner, and its not cheap. And if you are going to say to me "well then just beef up the GB?" that means more $$, and in the end, its still not gonna be all that solid of a GB.

Not that it wouldnt be cool to go for a boot around town with one, I just dont think its all that feasible. Even if I was super rich, id go and buy something just as fast, or faster, and I wouldnt have to worry about it.

My .02 for today

The engine bay on any of the RX7 series is exceptionaly wide, and has heaps of room for any small block V8. the 308 or 350 chevy make an awsome swap, the combo og high torque and light weight is deadly.

There is room to mount the engine far enough back in the chassis that handleing is not overly affected, infact the only problem is getting the extra torque to the road.

G/box strength is not a problem, as all the cars I have seen have used the manual or auto box that matchs the V8. However if you wanted to spend the money and get a custom bell housing made up im sure the stock RX7 box would handle a midly tuned V8 with out any trouble.

This is not an uncommon swap, however its not offten talked about as Rotory owners are sometimes very passionate, and dont like the idea of a rotary car being piston powered.

As for the cost? well its not as complex as you might think, espeicaly if you run the V8 on carbs. Basicly you need some custom engine mounts, and new end put on the Drive shaft. If your mechancaly minded and have access to a welder its a cheap swap.

i have an 87 rx7 with a 350 that has a ton of power. also a six speed tranny. everything bolts in nicely with proper kits. considering it has a fiberglassed wing, pearl white paint, tokico illumna suspension and a 152 db stereo, and turns everybodies head when i run a high ten second pass on a total of 15,000 canadian. try that with a very streetable rotary engine.

Ok. I retract my previous statement.

The LT1/T56 swap into an FD or FC for that matter is definately do-able. There's a guy on the RX7 forum who's been working on his conversion for a while. Granted he's going all out on his motor (he's loaded), but it's gonna retain the stock 50/50 weight distribution, weigh no more than stock, and have over 600hp. A place called Grandma's is selling a retrofit kit for V8's now too. $1500 for the kit.

The LT-1 and LS-1 swap for the RX-7 also isnt as heavy as most people think, since both chevy motors dont use turbos or intercoolers, the weight difference in actually fairly minimal. The V-8 swap in the RX-7 is the most practical thing ive heard about, plus you get better performance and gas mileage from a stock V-8 in the RX-7 than you do with the Rotary. Fuckin Awesome!!!! :smoka:

Swapping any cylinder engine into a Rex is retarded. It goes against the very essence of the car, for it was meant to have a rotary engine. The rotary keeps it uniqe and exiting. Call me a sentimentalist, but the rotary is the other half of the car, the first half being its beautiful curves.
