i was just startin' shit.


I've never been a fan of the whole "no replacement for displacement" nut swingers.
The vast majority of them are rolling around with stock engines, that are putting out the same power as some engines half their size, sometimes even half the number of cylinders.

EDIT: shit, a turbo rx7 with bolt ons puts down more power than my father's pick up truck and it has a big old fat v8 that has 3 times the displacement of the rx7.
a b16 Honda makes the same kind of power and gets twice the gas mileage of that truck.

no replacement for displacement doesn't really come into play, at least for me, until you start talking over 600 whp. And even then, its kinda eh,

 

well, for this topic (race engines) i could care less about some modded honda making more then a v8 that has so much gov'mint bullshit to make it "clean" and "high mpgs that you wonder why they even use v8s. If you put 10k into a honda I4 and i put 10 into a v8 i will make more power, and probably last for a lot more laps.

Edit: iam also, just starting shit

 

think of a engine as a air pump, the bigger it is the more air it has the potential to flow.


you can make power one of two ways n/a, either with more displacement or spinning higher rpms. you can not beat displacement if the same amount of tech is invested into both engines... plus a bigger engine will be more reliable with its power boosting the shit out of a small engine or winding the piss out of it will take a tole on its reliability.

Wow..why would someone go to such lengths to pull something like that off?

 

Working at a Machine Shop years ago the Assistant Supervisor to the Maintenance department torqued the head on his sons prelude where he didn't need to use a head gasket. The gasket was going. He removed it and just torqued the hell out of the head and it ran fine like that for years. Probably to this day that car is still on the road who knows. Haven't seen him since 05. Having a motor without a head gasket isn't anything new to me. I've seen it done before.

 

So did the fake ever get exposed?

 

Someone brought up the pic's about the block on page 16 on evom but nothing ever came of it....


IMO After reading the whole thread on evom and seeing alot of the big name's of the evo tuning world in that thread not exactly doubting what this guy is doing, I'd say it might all be legit....And if it is, this guy is building one of the sickest evo's set-up's I have ever seen...

 

I don't know about that whole 10 grand argument... are you including the price of the engine itself?
I haven't really ever seen a v8 that was worth anything for less than a few grand.
I know a lot of honda engines aren't that expensive. Personally don't know. I do know that if I threw 10 grand at my 240sx, that I would be making over 500 whp and I could drive it everyday.
I could get more out of the 240, but then I would be loosing daily driveability. The thing is though, even at that power level, I would still be able to get upwards of 20 mpg.

10 grand at my 300zx would put me into the 800 whp mark and I could drive that everyday. and that is only a 3 liter, still half the size of most V8's

Both of those are including buying a new engine.

There are pros and cons of both. It just depends on what your personal preference is and where your perception is. I have always been on the side of doing the most with the least. V8 guys tend to lean on the side of Have more than you need to get it done.
Building it with some quality and attention to detail makes the reliability argument totally void. Just because it is a 4 banger doesn't mean the alternator is going to give out any sooner than a v8 alternator. And as far as engine internals, I don't see why any engine, 4, 6, 8 cylinder would be built for power without either low mileage and/or a rebuild.
I seriously doubt you would throw 10 grand at a V8 without a rebuild. Hell, probably forged internals to hold up to the compression and boost and nitrous.

From where I am sitting, with a budget of 10 grand, I would venture to say that we would end up in the same spot, with the same usable power, and within the same track times.
and from my perception, that would mean the smaller engine was better.

 

its simple logic you have to work the 4 cylinder much much harder than a v8 to get the same hp. no matter what quality the parts are you are using that will still take a beating on the reliability side. what turbo's and nitrous does is effectively make the engine work like a larger engine, its allowing more fuel and air usage which is the same thing displacement is.


who cares about mpg when talking about performance that is a cop out, any turbo engine will make decent mileage if you stay out of the boost, hell my dads diesel can get anywhere between 8 and 20+ depending on how much i stay out of the boost in a 5k+ lb truck.

my friends mk3 supra has a ls1 turbo in it, it gets in the 20's mpg wise while making 420hp and 450ft/lb to teh wheels while on a very conservative tune because he's on 89 octane at the moment....


for 7k my new engine that i am putting together is going to have around 660-690chp n/a, another grand for a wet kit and i will be pushing close to 1000hp.


more displacement in a properly built engine will always net more hp with the same power adder used...
