LS1 without a doubt.
in fact I'd use an all stock 2001 LS1 and just have fun with it.
a LOT of fun with it.

no need for a bazillion horsepowers y0, I just want it to ROMP and it would do just that with a basic LS1 motor, as long as you have the chassis and suspension, wheels and tires to put that power to good use.

 

In my opinion i am all rotary, but if i had to put a v8 it would defenitly be a modified 302 block, cuz they can take a hp and spray them and they still keep on running hard, but that just my opinion and my taste.

 

Ok, BTW quit bashing the rotary engine already, its immature. this is more or less a dream thread anyways. Now, i have played with conventional engines and rotaries, and im here to tell you they both have their ups and downs; Rotaries have ultra smooth power bands, light wieght, less reciprocating parts, and will fit in ANY application. On the down side, they tend to wear a bit more because of the given up moving parts, they are relatively high maintenance(personal experiance with THREE engines) and difficult to boost high levels. The downside to the piston engines has to be the fact that YOU GET WHAT YOU PAY FOR. LS1's are cheap and powerful, but a race mechanic could tell you that their build quality is cheap, Not to say that ALL forms of LS1's are cheaply made, but the popular inexpensive swaps ARE. The upside to piston engines is the massive amount of existing knowlege about them. 90% of race mechanics could tell you how they work in their sleep. When i bought my first RX-7 it took a few attempts to understand it. On top of everything, THERE ARE CRAP PISTON ENGINES AS WELL AS CRAP ROTARIES. Its an even playing field in my mind.

 

4g63 six bolt with about 25 lbs of boost, making 500 horsepower. that ought to get things pretty quick.

 

lol.
you have some funny ideas/beliefs/opinions.

I would believe that truck motor LS1s can have a hard time with a roadrace use if left all stock, but who does enduros with a completely unmodded truck motor? nobody.

 

.....My beliefs are about as close to the real thing as possible. There is no such thing as a perfect engine...... it all comes down to what you want. And because the thread is titled "what v-8 would you stick in your rx7?" Im going to have to say....A CUSTOM CNC MACHINED 400 CI MODULAR V-8. With non- sequential twin turbo's(the 110mm variety) and all kinds of carbon fiber ****. Then even the v-8 guys would feah meh.

 

or shafferof racings 472 ci small block chevy engine. body of a mouse power of a rat

 

i like the lt5 for no other reason than its different

 

+1 couldnt have said it better myself!

 

if funds were unlimited I would without question drop in a 1997 Ferrari 355 engine and have an RX7 that sounds like this... http://youtube.com/watch?v=4LdaNknrWxs

and this. (skip to 1 minute and 36 seconds)

I do, hes a douche bag with a nice car he thinks is unbeatable. "thinks"being the operative word.

 

and near impossible to find. Those arent really even GM motors.

 

this ones for all the boohooers about how much they think v8's weigh.
400hp, 200lbs (put that in an rx7- it now has MR balance).

/\ win.

 

The LS1 is bigger, lighter, can take way more hp, you can spray more, and they will keep running harder. I lost faith in any Ford motor thats not at least 32v. My friend has an 04 GT with heads/cam full exhaust, full bolt ones and he made 313rwhp. He made 281 with just cams. My other friend has a bullet mustang with heads/cam and hes makin 318rwhp. My LT1 made more power cam only. And an LS1 cam only will make more power than a heads/cam LT1. Also,there are guys whove hit their stock bottom end with a 200 shot plenty of times. The stock LS1 crank is safe to 1000hp as is the block. A 302 block I think hits its limit at around 500whp.

 

seems to me like you think guys who own rotarys are idiots. its in your signature. I dont think im unbeatable. but i am going to beat you if we ever line up on the street. ill make sure of that. the only douche bag is the one whos talkin and doesnt even have their car running.

 

So your saying anyone who owns a rotary is an idiot? I guess you didn't learn how to read properly. And you'll make sure of that huh? You sound REAL bad *** when you talk like that. And who cares if my car isn't running yet? My trans am was faster than your RX7. You went 10.5 and you think your a God.

 

so because i have 1 video up here that is a 10.5 thats how fast my car is? yea i guess your right. Im more anxious for you to get your car done than you are. lol i cant wait to spank that thing. we will go on the track and on the street from a roll, just to make sure i beat you on both. and im gonna sound good doin it too.lol

 

Weedeater w/out muffler != sound good

 

nothing sounds worse than rice without a muffler.

 

If rotaries were ileagal, I'd seriously think about converting my car to electric.

 

LOL!

 

not that i think a v8 should ever be used.. if you did have to, what about an LT5? the zr-1 corvette engine.
its 400hp stock... and very tunable



its a 5.7 liter 4 cam small block, what could be better?

well, mabey some turbos

 

i only read the first page so i hope this hasnt been posted.

But the Hayabusa V8 For the motha ****** Win, bitches!

 

Doh!
