Thats a pretty retarded statement man. cheap compared to what? a $60k nascar engine? $100k top fuel race engine? yeah sure, compared to those maybe. but for a mass produced, engine sold to the public that you can obtain just about anywhere in america for a decent price, these engines are made of bitchen quality.

A friend was telling me, if this V8 was produced in the same exact specs by any other manufacturer, it would cost 3 times as much. Just imagine what an all aluminum V8 would cost from BMW or mercedes?

its 400hp stock... and very tunable

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

well, mabey some turbos

The only problem with the LT5, is going to be finding parts for the motor and cost. This was not a high volume motor, and I believe each one was hand built(Could be wrong about this though). It's definitely a badass motor though, and sounds so sweet. :icon_tup:

It also LOOKS much wider and taller than the LSX

Though I've seen the LT5 ZR-1 in person at meets, I've never had a chance to compare it in size to the LT1/4 and LS1+. I'd imagine it would be quite a bit bigger, but I don't want to make the assumption without seeing it.

I'm just going by looks...

Actually, I was referring to showroom stock racing, dumbass. The LS1 is inexpensive for a reason. It doesnt even begin to last in enduro racing because of this. I wasnt bashing the LS group, however. The GTO's LS2 has shown great promise on the racetrack in terms of reliability. Also, I dont build LS1's. I REBUILD them. Over, and over again. If this is a governing factor, the LS1's im speaking of are generally pulled and rebuilt from 99-01 camaro's.

In the argument about cost, i agree. But one couldnt even start to compete with BMW's build quality. The only problem with those engines is the cost of maintenance, other than that, if i wanted to last the entirety of a race, i'd pay dearly for the BMW if to better chances of victory.:)

Rotaries arent "RICE" The owners of such take pride in the noise they make because the deafning noise you hear isnt a loud exhaust, its the engine. Now dont ricers put loud exhausts on their car to fool the complete idiot that hears it into thinking its high performance? Yes. Rotaries are noisy, and obnoxious. but so are big block chevys. So I love them anyways.:lol:

turbotommy 03-22-08 08:55 AM

ya..... sounds so good. just like the sound i hear every tuesday morning from waste management

slo 03-22-08 09:02 AM

the garbage trucks where you live are LS1 powered.

I know your joking, but in all reality an LS1 wouldn't last very long in that application when compared with the diesel engine they actually do have.

Someone mentioned the hayabusa V8. ww.powertecracing.com
I wouldn't mind dropping the stroked 3.0 liter version in an FD.
I think the new M3 V8 would be superb, and its an awesome sounding motor.

A corvette enthusiast told me the old ZR1 motor had too long of a stroke too take advantage of it's head design. Can anyone here verify this?

To all that don't understand swaps.....

Try to get any significant power increase on a rotory motor without spending megabucks and
still be smog legal in California .

I love the rotary and still have my 85-SE , that I bought new , but I also have an 85 with a 5.0
that cost less than $2k to do the swap and was california smog legal.

Nobody cares about California. The rest of the nation is just waiting for it to fall into the pacific along with it's communist government.

California's communist ways are slowly making their way into the rest of the states. You won't be able to escape it forever. :wallbash:

If had to choose a v8 it would be the 4.6l DOHC v8 from the 2000-2004 mustang cobra w/ twin 57mm turbos. here is an ex of this in a 2004 cobra http://www.youtube.com/watch?v=TP9H7QkNjMM this engine is very reliable and strong.as compared to the countless times i have helped a friend rebuild his 2 305's and 3 350 sbc's i hate chevy engines they are cheap and easy to build but you rebuild them way to often and they leak all the time! i even helped him rebuild his 1958 L6 3 times from his 58 apache 36.

slippery93fd 02-16-09 11:29 PM

7.3 powerstroke would be fun

Monkman33 02-16-09 11:46 PM

a diesel in an rx7?

I would rather build a de-stroked high rpm v8 with turbos (or no turbos if the power was right)

I think a destroked v8 with a higher redline could be very comperable to a 20b powerband.

NoPistons! 02-17-09 12:24 AM

Fuck a v8.

If anything, i'd do a Grand National swap.

V6 3.8L twin turbo, nukka.

hassanbakar123 02-17-09 12:25 AM

ls1 ftw...
i have a lt1 but i wouldn't put it in because of the weight...
vh45 would be nice but not really that much support for the motor

the weight of a LT1 isn't crazy compared to a LS1, especially compared with a lot of the other engines that have been mentioned that wouldn't even fit without building a tube front end or putting a 6" cowl hood on the car.

F1blueRx7 02-17-09 07:53 AM

Also compared to an LS1 you're way down on power with a VH45 (about 280hp stock and not much aftermarket at all). They do sound awesome though and fit pretty well in the 240's.

LS1s are getting real cheap now anyway.

even with 1 turbo it should go "ok" :scratch:

Yes, cal sucks, I've since moved to Florida, but you can expect more epa interference everywhere , in modifying cars thanks to the liberal majority in the gov't .

It's like a one way ratchet, keeps tightening, but won't loosen.

Doesn't Maryland have smog checks ?
