LS/Vtech apparently not a sturdy engine.

IT looks as though a ls vtech is limited in its rev capablitys and is more inclined to blow because of its bad R/s ratio (rod : stroke)

Re:LS/Vtech apparently not a sturdy engine.
 

Jeff's engine looks pretty sturdy to me.

Re:LS/Vtech apparently not a sturdy engine.
 

Ya i was impressed with jeffs but did you read the article? I mean it is not that the ls/vtec is bad it jsut seems that the R/S is not very ideal and therfore means higher revs come at more of a risk.

Re:LS/Vtech apparently not a sturdy engine.
 

I have been hearing the same stuff about LS/vtecs. i heard they wont last past 40k. I wonder if its the same for a CRVTEC?

Re:LS/Vtech apparently not a sturdy engine.
 

who cares if they only last for 30 or 40 thousand miles...---- its not like all of us are going to keep the same motor in our cars for over a year or more...hell id like to change mine to something bigger and better every year.

the CRV uses the same block as the LS, just has a bigger bore...

Re:LS/Vtech apparently not a sturdy engine.
 

no i the Crv has the B20z engie in it not the same as the ls b18

Re:LS/Vtech apparently not a sturdy engine.
 

no he is talking about the block only...the b20 block is the same design...just bigger....pretty much its the same outlook but in a bigger perspective dude.

Re:LS/Vtech apparently not a sturdy engine.
 

Exactly, anyone who's enough into this ---- to do an LS/VTEC isnt into it for reliability. I personaly would go straight to a B20/VTEC unless you got a screaming deal on a LS block.

Re:LS/Vtech apparently not a sturdy engine.
 

me too, he's right, jeff even said it in his write up... the ls R/S isnt ideal for 8200rpm!

swap a b18c internals then? you might has well just get a gsr motor if you are really worried about that crap.

Re:LS/Vtech apparently not a sturdy engine.
 

first, it's VTEC. pop your ------- hood and read your valve cover.

as for the article, it's bullshit. ANY Engine is only as good as YOU or the BUILDER builds it.

OEM Honda is built to perfection.
your garage LS/VTEC probably won't last for ----. but, built properly, there is NO reason why it won't last for 100k miles.

Re:LS/Vtech apparently not a sturdy engine.
 

the fact that someone is building it themselves has nothing to do with the rod to stroke ratio which is the problem apparently with the ls block

Re:LS/Vtech apparently not a sturdy engine.
 

there's chevy and ford motors with 1.5:1 rod stroke ratio revving to 9 grand.

the difference between an ls's r/s and a gsr's r/s is with in a couple hundreth's of each other--- not tenths- HUNDRETHS.

if ls/vtec is bad, than so must be a gsr
:hammer:

Re:LS/Vtech apparently not a sturdy engine.
 

hammer?..wtf...and the differences between basically all honda engines' r/s is only a few tenths, and since its a ratio, little differences make a big deal im assuming

Re:LS/Vtech apparently not a sturdy engine.
 

totaly agree if you use new parts in the rebuild and build everything to spec then basically it is the same as honda would have built it on the assembly line. the only way the rod ration would come into play is if you were at 8200 rpm every time you shifted gears. an ocasional rev to 8k isnt gonna hurt the motor. if you look at the rod ratios in b16's and gsr's they are that big of a difference. i had an ls\vtec and built it properly and ran very strong for almost 2 years before i sold the car. it and the crvtec are the 2 motors honda should have built instead of the b16 and gsr!

Re:LS/Vtech apparently not a sturdy engine.
 

imo i would keep the like 600-1000$ u pay for a b16a or b18c head and spend it on like.. sleeves on the b18a

then go crazy with the boost heh :)

Re:LS/Vtech apparently not a sturdy engine.
 

stock parts? i dont think so, put some LS sized rods/pistons from like arias or some crap and im sure they can rev too.

Re:LS/Vtech apparently not a sturdy engine.
 

not sure the article is crap or how you could say that. Not sure where you get pop the Fing hood because yes under my hood is a vtech but it is a 2.3L vtech. An engine reving 9 grand at 1.5 ratio is stupid on stock internals but i am sure they are not stock assuming you want the engine to last at all. As far as saying Honda should not have made the b16 ..wow i just hope you can back that up cuase you might not think that the ratio is important but it sure helps out the b16. Pissedoffdelsol not sure why you think the ratio does not matter because i hate to tell you but it does. I am in no way putting the ls/vtech down cause it has shown good numbers but i was just putting up the post to hear input. If you dont like to rev high often or you like your engine to have more stress or you dont want your engine to last long then Ls/vtech is a nice build for power gains.

Re:LS/Vtech apparently not a sturdy engine.
 

he said to pop the hood because it is vtec not vtech buddy

Re:LS/Vtech apparently not a sturdy engine.
 

I've been spinning my LS/vtec 8400 for over 12k miles... and boosted for 5k. So far so good :)

Re:LS/Vtech apparently not a sturdy engine.
 

Well the last thing i want to do is go against Jeff casue you rock man i was jsut trying to get opinoins on the legendary ls/vtech. I mean i love your ls/vtech and your numbers are oh so sweet.

Re:LS/Vtech apparently not a sturdy engine.
 

why do you keeping typing vtech, is it the cheap chinese k-mart knockoff of vtec? (variable valve timing and lift electronic control)

Re:LS/Vtech apparently not a sturdy engine.
 

no clue i usualy think of it in terms of VVti not vtec but dont kill me for that, although i think vvti is not exactly the same(variable valve timing and ignition i belive.) LOL funny you say that because i am not asian but a little less than half my friends are..but only 1 is even close to a motor head. Damn i feel like a retard for spelling it with an h but oh well. I am not use to typing vtec(even though i know what it is) and i normally have not dealt much with honda stuff since all the people that drive any honda in my town are all the worst ricers ever. My whole family owns at least 1 honda but have only recently decided to build up one since I love boost so much and i am not gonna be boosting any of the cars i really want to anytime soon. I enjoy road racing any way i can and i am not entering a league this year in order to boost a car cause boost can somtimes overcome my love of road racing. dang that was too long a post.

Re:LS/Vtech apparently not a sturdy engine.
 

People have their own assumtions about the Ls/Vtec some good, some bad. I know a local guy who is making over 800whp on a Ls/Vtec :o and spins the fucker to 10grand.. heh

The reason the ls/vtec gets such a bad rep, is that kids with high milage 170k 90-93 integra's slap a B16a/B18c head on this old worn out engine, and dont use the correct fuel/spark management, or the correct vtec oil pump, and beat the living ---- out of them, and wonder why they leak, and make noises... ???

I'm happy with mine, so far...... Getting ready to redo the head all up nice, and get a new turbo setup, gotta hit well over 325 at the wheels next time on the dyno.

Re:LS/Vtech apparently not a sturdy engine.
 

man, that would be insane for a daily driver. do you beat the ---- out of that thing daily jeff?

Re:LS/Vtech apparently not a sturdy engine.
 

What do you think ;D

Re:LS/Vtech apparently not a sturdy engine.
 

OMG .. people are still talking about this. That old ass article is a pain in the a$$
