I dont know how much you can consider a german engine stock compared to an american engine stock.

German enignes are at a much higher state of tune when they leave the factory compared to the american engines.

Chevy has been huge on this latly but they will water down and de grade their motors for easier insurance for their buyers.

What this discussion will all come down to is displacement, and most german engines lack that.

If you take a v8 bmw motor (idk what s it 4.X or 5.X Litres) then compare it to the 6.2L ls9 SMALL block, and go mod for mod, the ls9 will always come out ahead because you cannot replace displacement.

Thats not true lol, with a correctly done swap it only adds 28 pounds. It'll handle fine.

And I tl; dr Audi's I5 > talk

compared to what? sorry GM produces them on a low tune system that still puts out 300 + hp for the ls1?

please tell me a motor that will out do the ls1 in these categories:
price range
mod 4 mod hp ratio
n/a max power
weight


the only german v8 i can image being close would be the 4.0L m3. but with that price tag you can buy a z06 with a 500 hp ls7 that will run a high 11 to low 12 from the factory. but the bmw will cap its hp a lot sooner than an ls1.



we already know you like heritage in vechiles Ethan, you've explained this a million times. but when it comes down to it, some people care more about performance than keeping the stock engine thats in it. if you really understood how easy the ls series engines can make power you would get it. its not the fact its a "v8 big displacement motor", its the fact it works. dont you wish you could push 600 whp n/a on pump gas in your "afro" that you have? or would you like to settle for 450 hp on high octane and forced induction, which would be slower along with a higher price tag?

the fact is, GM mass produces their ls series crate motors. they are inexpensive, aftermarket parts are litterally everywhere, and the engine just works perfectly. people dont buy a corvette, gto, camaro, ect to soley take out the motor/tranny/harness/ect. most people who obtain a ls series vechile leaves it in there and builds it. the chassis is strong enough.

we were talking cheap conversions not fully done projects you can make a rx7 with an LS1 into a 12 second car pretty damn cheap was my point

i never said it was impossible to do a proper build i was answering him as to why people threw LS1s into everything and it is because it is the cheapest way to drag race (for the most part)

Power:Weight ratio

k thnx bai

what about larger displacement says you cannot have a good power to weight ratio?

the LS series is proof enough of that

I didnt. He said theres no replacement for displacement.

power to weight ratio > displacement.

I think someone made an LS Series thread for this reason

displacement = size so if you get to the same power to weight ratio you still win... always

I answered that shit a few pages ago. People that are RX7 fans or S2000 fans or miata fans... w/e the car... They decide they want an engine for their car that is relatively cheap, compact(it will fit into a miata...), lightweight, easy to mod, easy to work on, and powerful.


There are so many benefits to putting an LS1 into an RX7 instead of building the rotary its not even funny.



It's simple, and I already said it once. People that have a car they like are LOOKING FOR A BETTER ENGINE.
