A lot of people gave this guy **** over on the RX7 forums when he first started this. Then when he posted when it was nearly complete he was getting all these praises :confused: .

I'm waiting for all you people who opposed to the SR in the Civic, to oppose to this, but I am sure after I said this you will say you hate it now, just to prove a stupid point.

its kind of odd were they put the turbo, isent it usualy on the right

The RX7 has a narrow engine bay, there are more pics of the engine bay, if I find them you will see that there isn't much room to keep it in its usual location.

I can't really tell by the angle of the picture, but they may have placed it there because of a room issue. The inner strut wall may have been too close to the block for there to be enough room. Who knows:p

It's an interesting swap though.

The only reason you think that is becuase of the valve cover, but it looks that way to match the color of the car. Trust me it's an SR, unless there is another car that looks exactly the same, it used to have a red top back in the installation days.

simple - notice the location of the oil cap?

SR oc is on left side
KA oc is on right side

not to mention the valve cover design is different, but the oil cap is most obvious.... looks like he just had it bead/sand blasted? is it painted?

Overall I think this is a really COOL idea... I think the RX7 is a sweet platform, but the rotary reliability and repair expense (given that they are not very popular and not many people really know how to work on them)

I want one :)

KiDyNomiTe, I can't hate on anything until I see how it perfoms.

I think swapping between cars is the coolest thing when done right. It brings the sportcompact world just a little closer to the Hot Rod community we will all inevitably become a part of.

This one looks good and depending on the power that it is pushing, I bet it drives great. All that I read on the RX7 tells me bad things about the engine durability so this has a bit of common sense in it. Sort of.

I like it.

As for that civic with the SR. that could be cool. I just question anyone that does swaps just for show. I think that is what a lot of people do in the states and so that is why people are skeptical. Why honda? It is the most popular brand in the import scene for show. People just put their guard up against "ricer crap."

oh of course. "they'll do the whole, nissan engines belong in nissan cars" deal. or "why take out a perfectly good engine and put in a lower revving engine". well, because he wanted to i guess. there are many fast rx7's out there, this guy's just going a different route. if someone doesn't like it, i'm sure there are a thousand other rx7's that are fast who have all done the same thing that they can gawk at.

That is basically how I feel about swaps.

About the RX7 reliabilty, it is reliable if you take real good care of it, it just takes a whole lot more work, to keep an RX7 running good and long. Any car can break, or blow, some last longer than others, but either way you have to take good care of it.

I wonder how it handles....but either way its pretty sweet.Although, I think I like the "supra-7" a little better. Just because the engine is larger.....but I think its ugly! :confused:

ONI-- you have mail.

The supra7 is f***ing cool. I bet that would haul a**.

Isn' t that engine heavy?? Might handle like crap. Again, great idea though. And again, I wonder if it is just a show car:confused:

Meh, I have no major beef with the project, just doesn't make a great deal of sense to me. Reliability issues aside, the rotary from the rx7 is generally regarded as a more capable powerplant. Custom exhaust manifold, intake manifold. . . Lots of time and effort went into the car, which I can respect, though I personally wouldn't have laid down my money on it. 'Course, it wasn't my money, so I don't give a damn :-)

My friend used to have a second gen rx7 FC3S. The engine didnt last to long on it. I think the sr in a FC would have been nice. Ive always thought if the FC had a more reliable engine it would be a nice ride.

now that i've seen rx7 with sr
i wanna see some rx7 with KA-T :D LOL :rolleyes:

02-02-2003, 08:33 PM

hmmm...why would anyone want to do that.....think about it the car was made and balanced to have a rotory engine in it...the rotory is a far lighter and far smaller engine...dropping an sr into a perfectly good FD totally ruins the weight ratio amongst other important factors that designers at mazda took into consideration when designing the rx-7...the sr is no more powerful then the turbo rotory the car comes with...so why then would you drop a heavier motor into your rx7, because its cool?:confused:

whateverjames

02-02-2003, 11:05 PM

he probably blew his engine. and probably didn't want another rotory. so his car handles 90% as good and is 40% more reliable, if he made a mistake he'll realize.

The cars owners own words:

"the 13b weighs 65lbs more, the back of the det sits about an inch further back and the front is is only 2.5" further forward....

Sounds to me like it actually HELPED the ability of the car

I think it weighing less may be questionable but I dont see how it would sit further back then the REW motor. Giving them them the benefit of the doubt that it does, I still dont believe it sits as low as the 13B. Also, the FD's 13B is capable of gobs more power then the SR on a mod per mod basis.

I wasnt able to see the pics but still a cool swap nonetheless. Original.

If I don't sell my 88 RX-7, I'm going to put a V8 in it when I get out of college. That would be sick, the car is lighter than a 240 stock with 50/50 weight distribution.

Stee Flo

02-06-2003, 08:47 AM

well if you put a heavy v8 in the FC, wouldnt that ruin its weight distribution?

toddnappi

02-06-2003, 12:37 PM

It adds about 100-150 lbs to the front of the car, so the weight distribution goes to about 55-60% front. No big deal. On www.grannysspeedshop.com they have a V8 RX-7 that kicks ass in AutoX.

some guy

02-06-2003, 03:12 PM

With all the money and effort to drop in a V8, you're better off swapping in a 20B, it's still a lot of custome work, but at least you will still keep the good weight distribution and IT"S ALL MAZDA. But it's you car, your choice. Like someone said before as long as the owner is having fun. :cool: If I have $10k right now I would buy a S13 fastback, Sil80 Conversion, RB25DET (yes it can be done with about $5k) :D, suspension upgrade and finally smoke every SR20 or KA power 240 of course. :o

The 20B swap can get quite expensive actually. And if the weight difference of the V8 is only about 100lbs, the 20B is about the same.

toddnappi

02-06-2003, 04:35 PM

Not only is the 20b one of the rarest import engines in America, it's also one of the rarest overseas. Good luck finding parts. It is a glorified engine, I would stick with the 13b.

i know this is late in posting, but i just joined up :)

the guy is from tallahassee, where I am at. it's a very clean swap and very reliable. he broke into the 10's in the quarter not too long ago. he owns a shop here...they do horrible work though besides that one car :)

11-03-2003, 01:49 PM

its both unique and cheap. a guy who did most of the work on the car, drives a 240Z that he twin turboed himself. he did the welding on most of the parts that needed it in that SR to FC swap. even made the headers himself. i'm hoping he can help me out.

yeah mrme...mine is a 280ZX. and i've joined this forum looking to get as much info on the SR20DET that i can :) thinking of that swap in my Z. i want to go fast for cheap, and that platform seems like the best way to go :) any thoughts? anyone know of a shop in florida that will do it? i've searched through some old threads, but it doesnt seem like there are many shops out there that could do that kind of work for me :( i'm willing to travel as far as Atlanta to Z1 Motorsports if I have to. comments welcome :)

**EDIT** Argh..even Z1 wont do it. :( **EDIT**

I guess people buy them for their super sexy body and don't know much about rotaries (or do know that they blow up a lot) and they want some pistons in there.

christopher

11-03-2003, 04:15 PM

I would suggest http://www.unstable-hybrids.com/ they say they are looking for unusual swaps. I question your intent though, since you could easily put a much larger engine in your car without throwing the weight off too much. If you are looking for cheap, the SR20 is not your only option. You could get V8s in your car for the same money and there are lots of sites on the web to walk you through that. Definetly not downing the SR, I have one, but know that you have options. I should hope that this thread would cue you in to that.

Good luck with your car though.

datzun

11-03-2003, 04:28 PM

Well christopher...I want to stay in the Nissan family. That pretty much knocks out the V8. I mean there are some in the Nissan family...but the cost would kill. That leaves me with only a couple options. VG30DET or TT. The RB series engines. VQ35DE. Or SR20DET.

VG30DET is cheap. However, to get any kind of good numbers from the engine, you need a ton of mods. Mods = not cheap.

VG30DETT is higher on the price scale. Has been done before, but little documentation. Engine will eventually be limited. Space is a factor.

RB is not practical by any means. Cost is killer, hard to get parts, nobody works on them.

VQ35DE. Not done yet. Cost of engine at the moment is pretty high. Not enough wrecked ones out there to be able to get a hold of one.

This leaves the SR20. Cheap...available...parts everywhere...done before. For the price...the best option.

I'm on limited funds and resources. I only have about 3K at the moment to put towards such a project. I can get the front clip from a S13 for 1500. Power to weight would be awesome. Power period would be easily obtainable without much modification.

Let me know what you think though. I'm trying to get as much info/opinions/comments that I can :)
