Huh i would have never guessed milage doesn't care abt rpm. So why do car makers keep adding overdrive gears again?

I mean you can do 155 in 5 th gear so whats the point of 6th since it doesn't have the power to use ut.

logalinipoo

For that matter 3 rd is all the rx8 needs

LSXREX

You're right. Maybe I was too extreme on that last statement. Rpm is important, sure, but load is far more important. If that was the case they would put the worlds tallest gears in those lil Eco cars. I'm positive I'll see 30 mpg with more tuning.

Comment was to show that this statement is not true. Hilarious how you'll edit my comments but not his. Whatever.

Oooooh I'm gonna tell the mods...... Oh that's right, you drive roturdy. I know the literacy rate is low in Arizona but if you sound out all the letters you can make out the sentence in the post above yours.

Maybe if you tried using your brain you would realize that there's a possibility you posted your response only seconds before I hit submit on mine, but apparently that's too difficult for you.

I must have missed something here. I was referring to engine cost itself, if you are comparing complete swap cost to simply replacing the renesis then obviously the swap is significantly more expensive in both dollars and time.

But every thread ive seen where guys are chasing 500hp in a rotary, it is a extremely involved build of just as much time, thought and money as a LS swap, but in the end is not nearly as reliable, or as fuel efficient if you care about that.

Cost per hp, when referring to engine modifications only, LS motors are way easier to make power.

The rest is preference, I like V8 engines, because I think their badass and,.. I dunno, maybe I need to compensate since I also have a tuned up duramax and a Camaro, but torque is pretty badass so I give 0 *****.

LSXREX

thats cool I didn't take it personally. I know you're just bummed you put it that REW instead of the LS. I completely understand.

Whatever you say chief.

Yeah, I'm sure he's bummed....


So much talk and zero action.
When you guys gonna run at the track?

Joker_andthe_thief

he should be costs about the same and makes way less torque and hes gonna have to rebuild it from normal use

Arca_ex

iTrader: (10)

First off, I will make more torque than he does. Second, my application is not "normal" use anyways.

Sorry bro, it's not a Renesis its a REW!
He'll be fine.

Educate yourself prior to making statments that make you look ignorant.

negative


REW with $5000 in upgrades < LS with $5000 in upgrades

no replacement for displacement = FACT

educate yourself bruh

LSXREX

REWs dont have a reputation for reliability either.

LSXREX

Whats funny is an FD will lose weight with an LS swap. So wouod that make an REW swapped RX8 hesvier than an LS swapped one?

Oy vey. Well, duh. But that just shows you haven't read up much on the FD now. The twin turbo setup is extremely heavy and the FD came with a ton of stuff. In fact, the engine bay is so packed that airflow is impeded. Its not uncommon to drop weight when going to a single larger turbo setup. Mazda made some sacrifices to display other advances. Most cars with REWs swapped in will not suffer as much from weight from that stock REW.

Literally take a look at the equation for density.

Density = Mass/Volume

So it is fact that you are wrong. It is also a fact we learned that in elementary school.

LSXREX

Lol I don't think density really takes reliability and drivability into consideration. you cant say with an objective view that a 500 hp rotor will have better drive ability and be as reliable as a 500 hp ls motor? And whether you like to believe it or not, the rotor along with all the turbo piping and oil cooler crap weighs as much or more than an LS. The V8 is simpler, stronger per lb (you would call that density), and has more potential to make reliable, streetable hp.

If only they made a car that came with the LSx motor in it already. That would be one hell of a vehicle.

Lsx blocks are a thing of the past. Many companies are modifying aluminum LS2/3 blocks for 450+ ci and 6 bolt head capability. Those motors often see 2000+ hp duty

He is talking about LS engines in general...........

LSXREX

Oh i see. Stay tuned for imminent disappointment.......

It was my understanding that LSx means anything in the LS family while LSX means a particular offshoot of the family tree. I drive a rotary though so I dunno
