93 rx7 should i go 2 jz or put back the rotary back?
 

So im new to this i just got my first fd its a 93 auto shell . So here am i thinking, i was just gonna buy a swap in just drop it in, my friend saying i need to change the interior harness as well a new exterior stick harness need to match, in he told me not to buy a jdm swap cause if the coolant seats to long in Those engine the seals get bad in i would start loosing hair quick cause those car could get you going crazy if not done right ? So help plz guys should i go 2 jz in call it the day or little by little get all the right parts to convert it from auto to stick in put back the rotary? So plz any advice would be nice thanks.

If I were you I'd go chevy 350. Any motor bigger and your adding dead weight and smaller doesn't give you the same hp to $ payoff. Really cheap, really common, unlimited potential. But you don't have to listen to the wankel nazis or me, follow your gut

Keep it rotary, the ls is good for drifting-handling wise its not the better choice.

I think v8s are for people that fail with rotaries

Rotary > Pistons

I'm not anti-engine swap, especially if done well. Nor am I a spelling, punctuation and grammar nazi. But sheesh....I got tired of trying to figure our what you were trying to say by the second line. And it doesn't appear English is a second language.

Rotary over piston I agree, otherwise I wouldn't own one, but switching to an 8 has nothing to do with failure. Just google the difference between the torque in the 350 and the 13b. Make sure if you do go with the patriotic option, upgrade your springs as well on your front axle and you're handling will not change

it was hard to read what you wrote. im with sgtblue on this on i gave up about half way thru. i pretty sure your asking for advice on which engine to put in.

i would say really think about what you want out of the car and go from there. each engine/trans/rearend has its own pros and cons. go 2jz and call it a day? if it were only that simple, im currently building this swap right now and def not cheap or easy. My guess is going with a rotary would be the simpliest because the car is meant to be that way. but just my 2 cents... Good luck with whatever you choose!

i would do a rotary man. engine swaps are cool but i give mad respect to everyone that does rotary's

and if youre a baller do a 3 rotor!

or even a 4 rotor!!!

I've never met an FC owner that is a hard enough cored Financial wiz to do that ..
For an average FC owner Surf and Turf usually consists of Spam slices and Sardines!
$20k engine in a 500 dollar car..It would be a Nice "sleeper" though..heh!

I say stick with the rotors, that is make the whole rx thing a thing.

I say stick with the rotary.

LS swap it!

Put in a JDM M/T rotary first. Enjoy the car the way as it was meant to be first. Then if/when that blows up, decide for yourself if going rotary is worth it. You probably want to drive it with a manual anyway regardless of what engine goes into it so you'll spend for that regardless.

2JZ is going to be BIG bucks to put in your FD. Not even worth it. Just buy a Supra.

Coming from the Toyota world, I think if you're not going to go with a rotary then you should consider a 1jz. You can get a full longblock including trans and wiring harness for around $2K, sell the auto trans and go r154 (rebuilt with Marlin Crawler parts) for another $1500 or so + clutch and flywheel - so add another $400-$500. Then all you need to do is decide if you want to go APU or keep the stock twins...If all you're trying to do is have enough to slide, then the stock twins will be more than enough potential. But as the other members have been saying, it's not a simple drop the motor and call it a day situation. It's always going to cost more to swap a motor that wasn't designed to be in your car, and there is also much more room for error in this scenario as well.

Personally, I'd like to see a 1JZ swap ;)

It comes down to a few things..

Money, Power and Reliability.

Now your rotary is going to be cheaper, as you can just pop it back in, do a gearbox and pedal box swap to manual, and spend the rest of the money you would of used for the conversion on performance parts..

So thats the money part of it..

Rotary's are very easy to get power from with less modifications than your V8 Or 2Jz, which will again cost less..

Theres the power part..

Rotarys are built for power and not for reliability, so if your chasing high Hp your going to have to put a bit of time and knowledge into learning to rebuild it, id suggest every 5,000miles..

Where as your V8 or 2j swap will be more reliable and last longer with high power..

My two cents worth.. Hope that could help.

I would do 1jz vvti/r154 only for the fact that the vvti 1jz is the smallest/lightest motor out of the jz family.

It's up to you
Ask ur self this
how much do i know about rotor engines or piston engines and go from there..
I took the hardest way IJZGTE and more expensive way but down the road is goin to b worth itand less expensive... :nod:
Jst adding my .02 cents

I think rotaries are very reliable motors, it's how people maintain them that makes them reliable or not.

i would not do the 1/2Jz swap unless you just long, heavy engines. For the prices described above, you could have had a V8!

seriously. You could have an LS1 for now too bad of a gig, and they sell the kits to bolt it. Better still, there is no change in weight over the front axle line, and just mine changes in the Y and X plane for the engines center of gravity.

It's your car do what you want at the end of the day.

If it were me, I'd stay with the rotary platform.

I would also stay with the rotary. It is just that something that makes these cars more special. No additional fabrication required so more money for other performance parts.

my brother and i just bought fds about a month ago i bought mine as a shell with plans to swap ls2 into it my brother bought a complete car running yes its cool and sounds great but now he got code 20,26,27 oil meatering pump failure so now he has to spend alot of cash to fix. he plans on getting power fc and omp delete kit but if i was him i would just 2jz swap it and be done with future problems

I would say keep it rotary. Nothing sounds quite like a built rotary around 9k rpm
Besides it's what makes the rx7 different from other cars
