Question from a future 240 owner...

I'm curious about the sr20det swap, and yes i've read about it, so no worries about that. i was curious as to if anyone here has it done on a 98 240sx what gas mileage you get when you stay off boost? and when you are hitting boost what mileage you get.

i looked in the faq but didn't see anything about this.

wtf you mean off boost???? your always on boost, it just depends what psi you are running. More psi usually means more fuel.

well i mean like under 3krpm steady(not hitting high turbo) and simply driving steady

if you mean stock boost. Well i would make the assumption that its just as good as any other jap engine out there. I mean there econo cars. I dont have an sr, so i really cant tell. But i would assume it gets good mileage. But it really depends on engine cleanliness. Air filter, spark etc...

how about this way of rewording it...

What gas mileage do people with sr20det swaps in 98 240sx's get?

lets look at how many ppl here have a s14

as i dont have on id hope for about 18-20 at 7psi

well i want to compare it from the stock engine gas mileage to the swap mileage.

it doesnt really matter what year the car is does it?? An sr is an sr. It would depend on the year of the engine, as they changed over time. Why do you want to know in the first place?? ARe you contemplating not getting an sr because of low gas mileage in this crisis of gas prices?? Put it this way its better than a v8's lol.

that's not true.... each year has special stuff added to it which increases weight to power ratio in the vehicle which can affect gas mileage. I want to know because i'm in the research phase of the buying process. i'm contemplating alot of things with the sr but gas was the first one... i'm also wondering maintence wise what all has to be done to keep it up, and if you have to use premium gas with the swap.


even 18mpg isn't "better than a v8" cause a v8 mustang get's about 18.

seems like your concerned about details...well a swap is considered illegal so have you considered emissions testing? (if u have it)

i think you can look up Sr specs for mileage. There shouldn't be a huge difference. Obviously, freeway mileage is more than city and driver characteristics play a big role so if you keep it under 3k... it's probably a lil' more than your average nissan 2.0 liter engine.

I average about 17mpg city, 24-26hwy.


Best I've gotten on the highway was 28mpg, that was doing 70-80mph all day on the freeway(300+ miles) with maybe 5-6 miles of city... and a quick bullshit burnout.

That's in my car... which is considerably lighter than most 240sx's... I'm around 2200-2300lbs with driver. So that should give you an idea.

yea, but what im saying is the year of the car wouldnt really affect it that much at all. I mean you probably wouldnt even notice. Wow you get 2 more miles out the tank yippee!!!. Your gonna fill up when low regardless so it doesnt matter.

If you are worried about gas mileage, get a hybrid car or something, stay away from turbos, V8s and similar engines.

The engine isn't always in boost. I cruise at about 15in HG(vac) everywhere and hit about 10in HG(vac) accelerating. Where your foot is on the throttle percentage wise determines whether you boost or not. Its linear when you hit the right RPM which is prolly about 2500RPM to hit full boost. Look at the MPG of a sentra or NX200 or 2k(whatever it is) and that is prolly what you'll average.

Thats not for you to decide. He didn't even say he was worried about the gas mileage, just curious as to what it is.

2 more miles is better than not having the extra 2 miles. You never know what kind of situation you will be in when the extra 2 would come in handy, so 2 more miles actually does = yippie

My opinion on gas mileage is "If you have a job, you can afford gas," If you want more gas mileage than a 240 can give, then walk your ass wherever you need to go. Or you can just sit and complain about how high gas prices are. But personally, I would much rater pay $30 for 3/4 of a tank of gas than not drive my car or even worse, walk to work. 0.02c

i drove a 84 k5 blazer 350 8mpg and had to run 92

had to fill up every other day

walking sux

walking sux

so did that car of yours :banghead:

this is the stupidest thread ever...


god damn it people cant you come up with something more entertaining for me to read at work

no i did a car swap with some one

then he let some one barrow the truck and they toped off the trany fluid and blew the main seals
now it just sits there

and the truck i swaped for i blew the engine up shorty after

so now im going to try my luck with an s14

this isnt HBO were !@#%&*$.

well dont be such a cheap ass and fill up when the light goes on. 2 miles aint shit.

Really. I make 6.50/hr and I rarely go past 1/4 tank. Me run 93 too.

HAHA, but I am a huge cheapass. I only usually have 1/8 of a tank when im driving. I got a better job now tho so I should be able to fill up more regular.

Are We still voting for nissanfanatic for president 2005. what happened to that idea?? Whos with me?

gas mileage on boosted cars depending mostly on the driver. if you can manage to stay off boost. which most of us poor guys try to do, you can get quit good fuel economy. however if your always romping on the gas hitting full boost, and flooring it down the highway expect your whole 16 gallon fuel tank to only give you 150-175 miles for non stop abuse. on the opposite end of hte spectrum, you can drive really easily and stay around 2.5-3K rpm not giving it any throttle, you will hardly ever touch 0 on the boost gauge then you can get around 300 miles per tank.

Word Tat. I used like 1/8th of a tank on a 5 mile run once. Hit boost prolly 50% of the time.lol That was actually the run where I popped that cheap coupler.lol

LMAO. I might put Kramer back in my avatar. He is the best.

lol ya but were you joking when you said "me run 93 too." that was funny to me i dont know if you intended it to be or not. "me never hit full boost and me get good miles" lol

wtf you mean off boost???? your always on boost, it just depends what psi you are running. More psi usually means more fuel.


BWWWHAHAHAHHAHAHAHAHAHAHAHAHGAH

That statement is only true if you drive an SRT-4. they make like 20lbs of boost at Idle...



































THIS THREAD SUCKZ TEH NUTZ

we need to bring back the funnist quotes page i tried to bring it back a couple of weeks ago but no one kept it up and going lets get it back and keep it back or how bout lets get a mod to sticky it

Lol. Yea i was joking. But Kramer is seriously the man!

im seriously the man. BITCH! i get more ass then johnson and johnson

I don't make boost unless I'm past 3500rpm and I push the gas past about 70%throttle.

i dotn amke boost because my SR is problematic and im poor so i cant fix the problems and im the man

But Kramer is seriously the man!

HELL YEAH!!!

The Ukrane is weak... Its vulnerable from all sides.

I am from Ukraine, Ukraine not weak!!!

countries that start w/ "U" are always weak its a fact same w/ "C" countries

i know its a joke but china is not weak, i don't think cuba is a push over either.

Columbia is strong, it's got thousands of Guerillas lol and Canada is.....well ok...it's weak, but at least it's safe and whatnot.

when i said "C" i was basically just bashing canada. and cuba is a pushover,cold war only strong because of russia. come on though cambodia, croatia, costa rica, chad, chille need i keep on

ahhh see those other countrys even didn't pup into my head. i kept on tryin to think of other countrys that started with a C. and i couldn't. but thanks for clearifiying. canada is definitly weak.

nomatter how much i want to disagree, i have to agree. we're not known for our power, only our beer, hockey and toques. anybody seen strange brew with bob and doug mckenzie??
