I know, I know, most people are gonna say search for it but the search wont take the words s4 and s5. Well anyway I was wondering if it is possible because I have a 1986 n/a rex, to drop in a 1991 s5 tII engine in. Are the mounts the same would i have to get a new tranny, how much would it cost, is it worth it, is it possibe , should i just sell my car and buy a tII or keep it and drop it in. And is it ture that the s4 models are lighter than the s5s.

 

Jesus christ.

It will cost you from 500 bucks to 40k dollars. I just depends on what you want to do. And it won't be easy. We see this kind of thread every week more than once. I am just a memeber I can't imagine how sick and tired the mods are about seeing this posted so friggin often.

 

Sell Your car and buy a TII.... OR Buy a RUNNING, wrecked TII and steal EVERY engine component, drivetrain component and electrical component and interior component off of it!!!!!

 

Hint: nexttime search for S4* and S5* works for me

yes its possible, engine mounts are the same, however tranny and rear end mounts differ IIRC (maby im wrong)

you will need all Turbo engine wiring and sensors etc

Its cheaper to fix N/a, Sell n/a buy TII but if your a do-it-yourselfer like many of us here you can do it for under a couple K

The S5 TII engine bolts right in. You can use your stock non-turbo transmission/clutch/flywheel etc. if the engine is not making a lot of power and you don't drag race. If you want the better TII transmission, then you will also need the rest of the TII drivetrain, which is a rather large undertaking. The main problem with this conversion is the electrical harness doesn't work, and it's a real pain to fix.

You should sell your car and buy a TII because they are only a couple hundered dollars more than a comparable non-turbo car. The conversion costs more than the price difference, the conversion ruins the resale value, and the conversion is therefore unnecessary work.

Yes, and the S5 suspension has a "dead" feel when compared to the S4.

BTW, I removed your duplicate thread in the Other Engine Conversions forum. That forum is really more for non-rotary engine conversions, but I guess it is difficult to know that from the title of the forum.

 

Dude, that swap isnt as hard as people are making it out to be...

 

Man is this forum getting friendlier by the minute. You may spend a good deal of time on this forum Santiago, but some people are new to RX-7s and this forum, and are unaware of the task at hand. And for Gods sake the first thing he said was that he tried to search for it, but he had problems with the search. So cut him a break.

 

But if you make more than $3/hour, it's not worth your time.

 

Not to mention that putting an S5 TII motor in an N/A car isnt that friggin hard.... Where the 40k price for the conversion came from, I will never know.

 

Were you to buy all new parts from the Mazda dealership for a 100% S4 NA to S5 TII conversion, and have them perform the labor, it would probably be about $40K.

 

Whoops, lol, s4->s5 swap, forgot that. My bad.

If anyone is dumb enough to do that, then they deserve to lose that kind of money.

 

note thats a gtus we put a turbo into, not a normal s5

 

Note I removed my post because I'm a dumbass.

dude you can do it, you dont have to have everything "store" bought.... you can make your own motor mounts, drive shaft and other things(with the right tools). you will have to change the wire harness and ecu for sure to have the engine run good. i am not sure about the coils but you may have to change them. also dont listen to these people i posted a thread about 3-4 weeks ago about a 3rd generation engine into a 2nd generation rx and all i heard was bla bla bla your dumb for posting that it will cost to much bla bla bla and i did it for a total of $300 not counting the price of the engine.

 

so if I'm getting a cheap parts car with everything I need for the conversion it wouldn't be worth my time? even though I can't find a freakin turbo in good condition for under 4 grand. And probably couldn't get more than 2 for mine, most likely less than 1600 due to some cosmetic stuff. Look guys, why is it that in every other thread people talk about how turbos are so much harder to find and soo much more expensive but in this one everyone says sell the N/A and buy one it's not much more??? I'm driving an N/A right now because I couldn't find one I could afford (read, at all in the SE) and now I'm doing a turbo conversion becuase I STILL can't find one that would be worth the money for the difference and don't have the capital to buy a whole second car right now..... >

Ok, I'm sorry to rant but reading this thread really pissed me off. Yes, it has been covered before and yes most of us have seen it before but it's worth bringing up every once in a while for people to read. I brought up a similar thread but I had specific questions. I say support the guy in what he wants to do. As for resale, what about people ripping out the inside for "weight reduction" eh? How many of us are actually planning on EVER selling these toys?

...........I'm done.

 

If you look, I posted that it was easy, and the whole store bought thing was a JOKE...You know? J O K E???



Your not very smart, are you?

 

I think its a very worthwhile conversion. Especially if the parts are cheap and readily available.

 

thanks J-Rat, I just got a little upset from reading the first few posts. keep up the good work

 

Ah yeah... $300 + engine for a 13BREW installed and running... and you don't even know what coils to use... uh yeah.. okay. I sure believe that.

 

Putting an engine into an engine bay does not constitute accomplishing a swap. It needs to run, and you obviously don't have the knowledge to accomplish this.

My guess: you're lying. There is enough doubt present that you have to now prove this, or forever be branded for your lies.

oh, and bla bla bla you're dumb for thinking you can get away with bullshit on here.

 

Any competent performance shop should tackle the N/A - TII swap (specially the half swap meaning just a motor swap) with relative easy provided you give them the right parts (wiring harness, AFM etc...) and the right info (these forums = cha ching hehe) and a FSM. Many people on these forums who are NOT mechanics but rather motivated people who are comfy with tools have done the swap with the help of a knowledgable friend or two...for the more experienced wrenchers familiar with FC's a swap can be accomplished in 2 days start to finish. It's really not that tough...
