will running 7-8psi on a ls motor last? i'm looking to build a mild street car with a ls-t but wanna know if its gonna last. also how much power would it be putting down/ thanks

 

how long I can't tell you that but I can tell you this: A motor with no sleeve or built components and proper pumps and maintance will not last. Not even 2 weeks. So if you want to be safe, try to boost no more than 3psi and tune the car and have a air/fuel ratio gauge so you know if your car is lean or rich. Fuel pressure should be at least 35psi at idle and 43psi running. Oil pressure should be at 25psi at idle and 55 running. if ur pressure is too high, you're going to have to chance your oil every 200 (two hundred) miles cause rich gas will make the oil blackened.

besides all that, run thicker oil.

 

and those are just basic stuff.

you'll learn the hard way

Ummm... Ok.... Neways, I boosted my LS and when we put the kit on the motor had 127,XXX hard driven miles... I had done perfect regular maintnence up to that point... The car now has 140,XXX and still runs strong as the day put the kit on, if not stonger... ... Definitely stronger... I've been bosting 7.5 psi with inline fuel pump and 12:1 Vortech fmu... I plan on getting Hondata soon to make it more safe and hopefully get about 20,000 more out of it before it blows..


Just be smart with it, do your research, take your time on the install and don't try to be Superman... Yeah eventually it's probably gonna blow, but you can prolong the process by being knowledgeable... ... Knowledge is the key...

 

i guess some ppl are just lucky but some aren't.

some can blow their motor in 2 days and some can have it last forever

Mosts who blow up in two days, don't know what their doing...

 

a friend of mine had a 2001 LS with only like 23,000 miles and he was running 7 PSI with 440cc injectors and an Apex-I fuel management and it was all tuned properly and whatnot he was running i think 240 at the fly and something like 217 to the wheels. NOTE: stock clutch, stock flywheel, only ran a 14.2 on azenis tires

exactly!

I boosted my stock LS motor @ 73k miles ran 4psi for 2 thousand miles, cranked it up to 8-9psi for another 15k, then up to 13psi for the last 8 or so I now have 99k miles on the motor. Still has 180-190 compression #'s and only 2% leak down. making 270whp too!

all this stuff about stock honda motors not holding power is in the past. You don't have to build a motor for mild boost. Just have a good set up. Let the set up make the power and run conservative timing w/ a rich a/f. Take care of ur car and it will last forever. The days of check valves, FMU's, and blown motors are in the past.

w/ a clutch and good tires it should go faster. I went 13.39 full interior DC2 w/ only 230whp. of course I had a clutch and bfg g-force TA drag radials.

 

7psi on a stock LS motor WILL BE reliable as long as the motor is in good condition. Anyone will tell you milage has nothing to do with the condition of the motor. Just make sure your compression test and leakdown numbers are good. As for mild power....my stock LS, on 8psi, with Hondata and 440cc injectors ran 217whp on the dyno. That's plenty for a daily driver, especially in the city!

 

he sold the turbo and the azenis already its running like 16.9's now because its tuned for a turbo and he sold the turbo, now hes running with my old injen short ram....that thing sucked

 

when people say there motor blew what blows exactly? i was thinking of shot peening rods and pistons just for the sake of peace of mind. but i'm only looking to boost 10psi max what can i run safely and reliably? looking for it to last a LONG time.

 

nice nice DIRep

 

bump for p1ccoloz...

because I'm interested in this as well... and because p1ccoloz is a cool guy, so far... *can't wait to get his coilovers*

 

heh thanks....hey my AIM sn is same as my HT one

Nine times out ten it's the rings that go first... There's really no way before you turbo the car to know if they're in bad shape or not... For 10psi get a good fuel management, ignition, intank fuel pump, and maybe a block guard or something... I'd also recommend ARP head studs and a new head gasket...

 

8psi 300@w ain't **** ne more

time to build that motha ***** and just booost n spooool

probably cause i've been sayin the same things (uh ya build motor blah blah blah) that's why I can't be any safer than before

now my car is finally done (engine wised) and i'm not plannin to waste my money on conversions or stupid HIDs n CFH. now i want to hit 380@w daily.

once u go turbo, u can't stop! bahah

 

oh btw, by "build b4 u go" just so it gives u a piece of mind later so you wouldn't have to keep chaning ur headgaskets or wondering what the white smoke means. it's BS to hear someone drive their car (stock n turbo) for years. maybe they just don't drive their car or maybe a show car.

I have piece of mind w/ my stock motor because honda built it. I never had to change a headgasket never had to worry about white smoke. I drive my car for years and I don't BS. I race my car daily. I roll BFG drag radials daily because if I didn't I wouldn't have traction and I would loose 90% of my races. because I race daily. No show car here. Just a stock LS motor, 13lbs of boost, good reliable turbo set up and a good tune. Over 25k miles boosted on stock motor **** a built motor.

Owned... ...

 

If ya do it right, youll have no problems on those numbers. Fuel delivery and tuning is key.

yo p1ccoloz wat happen? i thought u were gonna sell ur ride n pick up an sti???? isn't that why i resized ur pics in the other thread??? no new car? keepin teh teg?

 

nope still going sti, once it's released. looking for a project car to beat up on. just a thought cause i'll dry at the first scratch on the sti! probably drop it in a del sol or crx

ok if i were to get an ls motor do all the routine leakdown and compression test and the motor is in good shape. then threw in a block guard and got it properly tuned would it last me a few years? how long would a built bottom end last boosted?

i have a difference of opinion, just like all the other boosted individuals who run more than 7psi daily on a block with over 100,000+ miles on it. you can run 7psi safely as long as your motor is in good condition and its gettin the right amount of fuel.
