Lighten the **** up. We were kidding.

With all this information you must clearly own a 400rwhp SR20DET and drive it every day. Maybe we should all shut up and listen to you?

It's 8am here Pub doesnt open until 10 Nah I just worry about guys who think a 400rwhp SR20 is reliable and totally driveable on pump gas.

rpm_pwr

That's true... down here in Aus it's rare to even hear about an SR20 that can produce that sort of power. There are some with around that kind of power but they are very rare... only a couple/few.

Don't get me wrong - I love some Nissans... the Silvia's and Skyline's but I just think that engine going into an RX7 is wrong.

Do you guys get S15 Silvia's in the States?

iTrader: (1)

S15 Silvias are not sold in the States.......the latest model of the Silvia we have is the S14

i dont agree with the swap but its better than a V8 in my opionion

if it was me i would have stayed with the rotary....its always nice being asked "whats the CC on that?" and when i tell them "654X2" they get so confused i love it

rotary for life

Would this nissan swap have anything to do with that high dollar 13b tt locking up more than once or twice ?

tnt

No the 13b was running fine when i pulled it and began this project, I felt that i wnated to do something different that was fairly affordable and i felt more comfortable and familiar with, not to mention the amount of SR swaps that we do and get calls on is growing exponentially so i figured let me see how it works out in the FD

I have more oics that i will post tommorrow for those that care...

the only reason the RX-7 is used for these types of swaps (i.e v8,2jz,sr20) is because if its superior body.. suspension, weight,and characteristics that those cars lack. It is his car let him do whatever he wants to it, but if i was gonna do a swap i would have gone 3 rotor.

I was gonna wish that Santa brought all you nay-sayers a lump of coal, but I think I will ask him to place a piston in each of your stockings.
Although I said great gas mileage and 400rwhp in the same sentence, I never said 400RWHP on pump gas. However, what is the problem with creating that kind of power on 93octane? My buddies 280 turbo made the following on 94octane gas. BTW, this is at the wheels.

Come on folks, what is key when trying to make power in turbo applications?
-Can my turbo flow enough to make 500hp?
it will have to flow roughly (500*1.6*.07)=56lb/min
-Can the intercooler flow enough and provide the necessary efficiency with a pressure drop below 1psi(core)?
it will have to have a flow of (500*1.6)=800cfm with a desired efficiency in the 80%+++ range
-Intake manifold
greddy jobber works well
-turbo header
how about our custom 321SS header
Don't act as if this is rocket science and I also used to think it was difficult. 400rwhp is not an overly ambitious goal, but does require some knowledge and skill. Hell, I am getting about 475@wheels from technology developed in the late 1960's. I don't even have the advantages of cross-flow heads, 4 valves per cylinder, pent-roof combustion chambers, aluminum block, yada yada yada.
Dear Santa, please do not deliver these folks any more Ricer mags, they are beginning to believe everything they read!

Hey this reminds me of a post from 2 months ago.

I can't believe people that own and love their rotories can be considered as not "thinking outside the box". Its good to do what you want with your car, thats what makes things interesting. But I'm not sure what kind of response you were expecting, the responses I see are what I expected when I read the title. I hope the project goes well. (or you put the rotory back in).

240z:
Wow what a truck!
90% of max torque between 3750 and 4750!!!
Hope he has one hell of a close ratio box behind that thing!

for comparason purposes here's a massively ported, over-turbo'd all-out 13b dyno (it was the 1st i found):

That there is a powerband 3x wider than your friend's motor.

Now dont get upset. I'm not saying the rotary is the best motor on the planet (hell it's not even close) but on the same fuel with the same turbo the engine with more displacement will have a wider powerband. What your friend's excuse is I dont know!

Cheuk in Seoul

If you really want to be different... why not swap in a Hyundai 2.0 Beta engine... I've seen them make 680+ Wheel HP.

This is a swap I don't really understand. A bigger engine with more room for power I understand... ie ... LS1, LT1, Supra or Skyline engine.

"They will be led to believe that 7's are 4 bangers" Here in missouri everyone thinks that already. and shaun, good luck with your car, but don't expect a bunch of rotary enthusiasts to be too excited about it. i also thought it was kinda funny that 240 z chastized all of us because we feared something we don't understand, and you stated one of the reasons you're swapping out the rotary is because you're more familiar with the SR20. as long as you don't put altezzas on it, we'll still be able to get along

Definately an interesting swap, but since you preach of reliability. How reliable is that engine when pumping out 400rwhp? That is quite a lot of horsepower for a 4 cylinder when you think long term mileage.
Any engine will not last as long with more power.
What engine internals are you upgrading?

Good luck with the swap.

My problem is that i understand this is a place where rotaries are loved, but by the same token there are to many closed minded remarks and stupid things that are said, I run a business and as such I have to be open to new ideas the reason I am not doing a 2JZ is because it has already been done and secondly it unbelievable expensive, on the other hand I would love to do the RB26 but once again I can not afford that kind of pricetag.. This swap is affordable, very close to the rotary in wieght (50/50 weight dist. that you guys bitch about when someone puts a big motor in), i am retaining the the sway bar in its factory location etc.... The car should still handle well and match the rotaries HP and have greater longevity IMO.... Yes I did put a piston motor in because I feel more comfortable with it but i also explored the possibilities of my 13b, you all seem to forget it was single turbo, streetported with a haltech and was making 386whp @14psi, so it is not like I just bought my seven and chucked the motor... I am having fun doing this and watching the replies because it is better than the normal posts on this board like 82,xxx and I blew my motor who should do the rebuild.... For all who have an open mind thanx for the interest for those that do not thank you also because every post you make shows what is wrong with this board!

Start of the manifold..

Brad

Yeah, except crispeed is running ALCOHOL, a custom sheet metal/tubular intake manifold and no intercooler!

I don't think that is a valid comparison to a street driven SR20...

This one is probably better




BTW, that was on 108 octane...

What's with all this close-minded, open-minded stuff? It's not like dropping an SR20 engine into an FD has never been done before, neither does it make the person(s) doing it any more open-minded than the rest of us rotary owners. It's just that rotary engines make the car special, and people are voicing their opinions on why it should be kept special. Agreeing or disagreeing with the swap has nothing to do with being open/close minded. It just comes across as a blow to 7 lovers, when you remove the heart of the car. However, it is your car, and you are the one who matters when it comes to driving it. So good luck on the swap, but don't be upset when you read replies that don't favor it.

stevecod

TNT, let us know when this is all done. looks very very good so far. at least it's not a V8 in a FD.

tnt

I guess you would call this an opinion and not a dumbass remark that serves no purpose... I have no problem with constructive criticizm just stupid remarks.. That type of remark is what i meant about being close-minded I apoligize if I offended you that was not my intent...

Thanx,
Shaun

Also I have never seen an Sr in an FD in fact I put that very question on this forum and no one said they had seen it, but if you have point me in the direction I would like to see pics...

I think it's all about origionality. I think it's a great idea. Who really cares anyway? It's not your car he's swapping. Good luck with the project!
