There's just something to be said for an engine that with only bolt ons (heads ,cam intake, exhaust) can make 475whp NA all day every day and get 28mpg on the highway. I was always a proponent of japanese engines, still am actually. The only American engine I'm a real fan of is the Chevy small block variants. But damn, you can't beat the bang for the buck of the LS series engines. Throw a turbo on an ls1 and you've got stupid power with very low boost levels. And I also hate that super loud monster truck sound that alot of those engies make, but you can make them sound much better if you put the right catback on it.

 

i got the rotary, with 90k when i did gt35r single turbo conversion...and i just broke 100k last week and engine is strong as ever...never rebuilt or ported.... and with my tune i got over 600 miles on one gas tank... from columbus OH rx7store to rochester NY...

Jason did relay good job tuning it...

i made 346 RWHP and 290ft @ 12psi on 93 pump gas with 4x850cc injectors

recently i raced with dsm eclipse that was running 22psi same turbo... 40mph roll and he couldn't get in front of me he was keeping up i couldn't pull away.... i let of at 130mph
...
i do not think any stock corvette would keep up or any rx7 with stock ls1 swap...
i raced rx7 with ls1 60mph roll when the car was stock and we where even

and my car is not setup for drag racing...

so i do not see any point in swapping out the rotary for a v8...

+ rotary was one of the reasons i got the car in the first place....

 

Rotors, and will never have anything different. I've already owned a Z06, so if I wanted to have an LS in my RWD car, I would have just kept it. The V8 swap doesn't make any logical sense to me. Rotaries are as reliable as anything else when treated right. I understand people get frustrated or just don't comprehend the rotary, but there are literally thousands upon thousands of Corvettes, Mustangs, Camaros, etc for the same or cheaper price than a FD, so if you want a V8, just skip the swap and buy one of those.

 

thats right

 

That's about 34 mpg. I'm throwing the bs flag.

Edit, I looked this up on yahoo maps and it's 395 miles in reality....more believable, I've gotten 320-330 miles on a tank freeway cruising with occasional boost

 

Im not giving you any crap and I am not against rotories but come on" Rotaries are as reliable as anything else when treated right"... You rebuild your engine and I'll rebuild my v8 and let's see who's lasts longer

That's just my opinion

 

no bs man.... i drove the car my self ... from OH to my home one gas tank....
i was thinking my level Sensor was not working ...

 

I've routinely been getting 360+ miles a tank driving between SD and LA. That's at 85mph, AC on and driving aggressively. I've achieved 24-->26mpg on the same trip while driving 'nice'.

I don't know think one is any less reliable than the other. It seems likely that it is highly dependent upon usage and how the engine is maintained.

I've built and raced V8's for years and over time I've embraced the rotary as being generally more reliable and needing less attention, at least for my style of driving. I like to do a lot of high RPM & power shifting and you will eventually kill the valvetrain in any piston motor with a lot this. Valve train components and valve springs in particular do wear out and eventually need to be replaced to maintain best performance. Float the valves a few times, especially with roller tappets, and see which motor is more reliable.

Another myth is that piston engines are immune to detonation. Untrue, they just don't necessarily show damage right away (and it is cumulative). Collapsed ring lands and piston skirts are very common; enough pounding and you'll pound the rod bearings out and/or walk the main caps. A few weeks later, when you start it up and spin a bearing or have chunks of a piston falling out for an unknown reasons--you will likely never attribute it to the detonation that caused it.

 

That's not an apple to oranges comparison. The LS1's have double the displacement of the 13b and therefore are half as stressed for any given power level. There biggest advantage is having more power in the low end. You don't have to drive them hard to get decent performance out of them. I've notived this with my 2000 model BMW M5.

Oh and FYI where not going to turn thread into a hp per liter dispute. 13b breaths like a 2.6 L engine and that's a fact. That's why I said it's virtually half the displacment of an Ls1. Displacment wise, an NA 4 rotor would be a more fare comparison.

 

fair

 

 

Your slipping because I also mis-spelled displacement the 2nd time around also.

 

A lot of money into my rotary, wish I had gone LSV8.

 

DAMNIT!
lulz, good catch. fair/fare is one of my biggest pet peaves, as is you're/your, there/their, etc... dunno why I didn't catch displacement tho.
/grammarant

ANYWAYS
here's mine almost a year ago, I blew it up a month and a half ago

and here's my friends


and another friend with a v8 in his FC just blew it up...

 

Wow, i'm all for cool projects but that looks like a gigantic PITA. I think that picture is giving me indigestion right now. I have to go.

 

 

I have nothing against other people sticking another engine in their car...

Modified rotaries can and are a pain...

I love my rotary and I love forced induction, it has been super reliable and takes everything I give it. I'd love to have a 3 rotor over any v8/2jz/rb swap.

I will probably never run more than 480-500whp with the 2 rotor simply because I dont wanna worry about the transmission every time I give it the business.

When I want more than 500whp Ill probably go with an LS swap and a procharger/turbocharger and run 600whp all day and never have a worry in the world.

 

Work-in-progress

MMMMmmmmmm....taste the rainbow...
