Don't swap... Rotary > Pistons. (If you maintain it well)

Do the swap, don't listen to the rotary fanboiz.

atruerx8racer

Buy/trade the rx8 for a nissan car and then swap that engine in there if you want to. Don't change what the Rx8 came with. Rotary enthusiasts = Rx7/Rx8 owners. Its like being like one of those "aholes" who swap an LS1 into an Rx7 (A Single/twin turbo rotary will put the LS1 into shame we all know that!) Please don't be like one of em. (Dont change what the car came with, change the car if you want to get a different engine) Peace.

It is your ride so do what you want. I hope you have lots of money saved for all the issues that will arise though. Do you live in a state that permits swaps? If you do not know then be sure to check.

If you want the car running soon, buy a new renesis. I dont care what the shop tells you, it will take quite a while to get this project done properly. The other thread was going for well over 4 months without being completed.

If you check the thread it is more like over a year now without completion . Just checked - he started the thread 23/01/08

I've seen guys on here up and running in less than a week after buying a second hand renesis . How long do you plan on keeping the car ? I would take a bet that says your installation guys wont hand you a completed car back within 6 months .

He says he needs his car up now

Wants to do a swap....

DOES NOT COMPUTE

i feel you on this. I love the Renesis and everything but lets stop being niave. THEY ARE UNRELIABLE. They say "take care of it!!" There are "rotary experts" who's engine dont last. I would name a few from this forum but i wont cuz it not my business. But lets all be real. How many solid running Renesis engines are at 150,000?? I've heard of a couple.

Do the swap. More power & reliability is always a plus.

^well 1 I think you would b surprised at the amount of high mileage 8's that are running arond here on this forum and ppl that have no clue about this forum....as for 150k yes there are ppl out there but this car is only 5 yrs old we haven't had the time for most ppl to get up to that mileage 100k yes alot of ppl are rolling that over but 150k is about 30k miles a year when the average person only puts on like 12k a yr....

me I drive ALOT and only manage about 22k a yr or so....give it another 2 or 3 yrs and you'll see plenty of 8's in that range...yes you still hve the ppl that dont' don't know the difference between a car and a truck let along a rotary and a piston engine..there is the factor that they don't know how to take care of it....

almost every normal person get's in their car and drive is no warm up just drives it and tried to change the oil within 10k miles.....well with the 13bMSP(or rotaries at all for that fact) that just doesn't work......yes I will be the first to admit that some 04's and 05's had problems with motors going early but that is because mazda's OMP rate was TERRIBLE it was not a design flaw. It was a programming flaw......

BTW i'm not being a rotary fanboi! haha

freaklinkmusic

yeh you're right.. but compare than number to other cars..

our car is only 5 years old... so how would comparing this car to others prove anything?

m477

They haven't made the sr20 for many years now, so you really think some old used turbo engine that needs a hack job to be put into a car it wasn't designed for is going to be any more reliable than a brand new OEM engine? good luck with that

If you're going to put a banger in, at least go for an LSx.

If Mazda is giving you a free motor replacement I would take it. I can understand if you want to work on a swap, but why not take the free motor and at least keep it as a back up, or sell the damn thing on eBay. If you are planning on really modding your car I could understand the swap. If you blow a reman-rotary that has been modded the dealer will tell you to get lost.

oh, my mistake. I didn't pay attention to the year. In that case, it's even less realistic to get this done anytime soon.

He was joking I believe. Swaps bring up problems of their own. Even if the renesis goes bad, it would be quicker, cheaper and easier to replace it and turbocharge it. It doesn't sound like the point of this swap is to increase potential power... He hasn't stated what kind of power he wants... but if he was looking for something in the 350 range, then he'd be much better off with turbo renny. If he's looking for upwards of 400, then sure, a swap might be a good idea.

They arent. They should, and he should either go to another dealer or contact MNAO and complain. You don't need all your oil change records to still have warranty. So either his dealer is retarded or he's making it up. But I've seen enough retarded dealers to lean more towards that answer.

off the topic.

how can you sit here say the engine is unrealiable?
for starters, we dont even know if the engine failed due to the owner not maintaing the car correctly, or the engine just failed on its own.

i am not here defending the engine, but please use some common sense. if you are baseing statistics on how many " I have a new engine "thread then i really dotn know what to say. because most of those threads dont even explain what caused their engine to fail. but yes some of those guys most likely had legit reasons why their engine failed. but its hard for me to believe that all of them maintained their car correctly, and this goes for any car.


and to answer your last questions about being real,and how many solid 150k 8 are running. well it is a 5 year old car. but lets be REAL, if you had any sense before posting that last comment , i dont think you will find to many 8's at 150k. but that is just me being real

back to the topic.
op you do whats best for you, and gl to you.

While I 110% agree that he should keep the rotary, you can get an SR20DE (not DET) shipped from Japan with < 20,000 miles on it. I think he should do a little more research on what kind of SR20 he wants if he has his heart set on it. There are a quite a few (http://en.wikipedia.org/wiki/Nissan_SR20DET) versions of the engine (mostly turbo upgrades), and even 3 blacktop versions.

If you go with an SR20 and you have a large amount of money to burn, get an SR20VET, it would require some huge mods (AWD platform to start with) but 276hp AWD Turbo and its built from 2002-present, or go with an SR20VE and then tack on a turbo, 204hp 2001-Present (roughly $1000-$2500 for the VE engine alone).

Stick with the rotary (if its replaceable for free from the dealer), buy an S13-15 and spend the extra money on that if you want to run an SR20 (or RB26DETT )... Just my $0.02

To me this swap is cool if you're going to do it yourself, know what you're doing, rebuild your engine yourself etc. Because remember, just because you have a recently rebuilt sr20, does not mean it is suitable for much turbo gain in its factory form. Which means you'll spend an arm and a leg just rebuilding the engine to handle your boost. This means new pistons should be forged, new rods, knife-edged crankshaft, and then the whole head which includes springs, valves, etc.
Lots of money.

Plus if you hire someone to do this swap for you it will cost way too much money.

Also, if you hire someone to do the swap, you have to really make sure they know what they're doing. Otherwise you could be out a lot of script.

what makes a car interesting is what the owner has done to it. I would like to encourage doing something different from everyone else but use some common sense. Dont go just throwing money around causing new issues for yourself.

I still have no idea why someone would want to swap an SR20 motor into an RX-8. I can understand people who swap LSx motors for gobs of low end torque despite the fact that I would never do that to a rotary. It just doesn't make sense to take an older, peaky, Nissan piston motor and spending the insane amount of money and time to get it swapped to an RX-8. If you have that kind of money why not swap in something GOOD. Swap a 20B or a LSx if you are dead set on getting away from the rotary motor. Or ...here's a thought, buy a car suited to a piston motor that *gasp* has a piston motor in it already. This is one of those swaps that I can only imagine being done by someone with more money than sense, or a really badass gearhead who wants to try something new. Guess which one is more likely.
