I was wondering what engine swap for the FD chassis is the best when all things are considered such as cost, ease of install/drop in kits availability, and keeping the chassis as balanced as in is stock? I'm pretty much torn between 2jz and ls1...

This thread will have the ability go on for eternity!!
The best advice I can give you is to research further in the other engines and V8 Sections and choose for yourself.
It's a Big can of worms to ask which is better even though you want to go Boinger engine.. as some guys will say Stay Rotary and others will say that they went Piston and never looked back..blah,blah..blah..............blah!...

I'm not saying search!..what I am saying is It is YOUR car,and your Prerogative to put whatever you want in it.If you own it,you should be able to make decisions as to what you have in it.
The info you receive on a Rotary Car Forum may be a "little biased"!

Does anyone happen to know which of those two are easier to install, cheaper, and which has the least negative effect on the cars balance and handling? The answers aren't subjective like the thread title. These are factual questions with factual answers.

My guess would be the v8 swap would be easier and handle better.

this Nissan sounds funny

every person will have a different answer. It depends on your intended use. I wouldn't advocate a swap except for either freak factor or because your rotisserie is popped and you got a crazy deal on whatever you are thinking about dropping in.

the best engine swap ive seen so far that produces GREAT power and really suits the fd is a 13b.

2jz is a LOOONG heavy motor.

2jz is best after 20b

First thing, Set a number aside. $8,000? 10,000? $15k? then find a swap to meet your budget.. Engine/Trans/Wiring/Ecu/Mounts/Fuelsetup/Things to make your ac/ps work/swap parts etc....


v8 SUCH AS AN LS1, yes a great motor but what people fail to realize after they spend at least 5-6K for a swap ALONE. What if the trans take a ****? um at least $1300-1500 for a Good USED one. Ls1 engine long block $1800-2000.. smh Now lets get into the swap kit how much is it again? a couple thousand..

2jz swap there are a few ways to go about the swap just a sc300 2j for $400, Supra tranny $600-700 another 3-5k in turbo parts, ecu upgrade, mounts, inter cooler etc.. If the engine breaks oh $300 for another one. With the right turbo setup and tune easy 500-600hp.. Stock block. This goes for an Rb25 and rb26 but the exhaust would be close to the steering shaft.

There are alot of engine choices and any engine setup you go with, you can always do things to balance the car around your setup. Just an FYI.


No matter what kind of swap you go with make sure you do your research down to the letter.. Always by your mount kit and supporting mods before the engine itself so when u get the engine you can install it right away and see if its good bc most warranty's are 15-30days.


If you have any questions pm ive done many swaps in almost every kinda car out there.

Good luck bud.

is it cheaper to swap than just building a good Rotary?

Dumb question....what is the reliability between a 2Jz vs a LSx? Can I get 150,000 miles on a 2jz without major maintenance?

LSX By far. the 2jz is a very stout Motor . and will make more power then Most LSX's , but it is also very long and heavy so the handling WILL be affected, the support to swap isnt as readily available ..

now an LSX depending on the X you can make from Stock FD motor power out of a stock LS1 , to quite a bit more with upgraded cams and such . and you will have alot of torque . all over the place .

there are alot of kits to swap it in . premade stuff so you dont have to measure cut measure cut , weld

they even sell kits to use the A/C from the LSX in the FD .

Also the LSX can actually give you decently ok MPG's and its very reliable just make sure you give the motor a look over before you install replace any seals that may need it.

you need ot take all of these things into account .


As for comparing it to a rotary rebuild again it depends howmuch power you wanna make what your goals are for the car. its normally cheaper to make a 13b But you can go crazy with a motor rebuild LOL

if you are worried about maintenance costs you may not be in the right field there is always maintenance specially with rx7'sand swaps my friend's LSX fd he's had quite a few things to do maint wise . but thats just normal with any modded car.

when you replace something a new part becomes the weakest link in the system.

Well I expecte some maintenance of course. your right any modded vehicle will require maintenance. I guess what I meant was drivetrain maintenance. You can't tell me if I drop in a crate LS2 or LS3 engine and tranny that I am to expect things to break on these parts within a few thousand miles? I highly doubt it. What would be the point in buying them?

Now I see all the accesories that required to do a V8 swap might break here and there because there are a lot of parts to be modified. Then I am willing to take that risk.

Whizbang

im curious where all this 2JZ everything! fad is coming from. I understand that the engine is pretty good for making a lot of power. But its long and heavy and the delievery of said power isn't that condusive towards what the Rx-7 is meant for, handling. And for a 3.0L the non turbo model is basically asthmastic @ 220 crank hp.

the LS1 is lighter, compact, and strong as you need it to be.
