lsvtec
 

i need some thoughts or advice about lsvtec

Re: lsvtec
 

you might want to be just a taaaad more specific.... ;)

Re: lsvtec
 

lol my buddy has one....seems pretty quick....lol is that what ur looking for? u need to narrow your question down a lil bit.

Re: lsvtec
 

try posting this in hybrid tech youll probably get alot better info

Re: lsvtec
 

I had one, it was pretty fast, unreliable as ----, but nothing near boostin

Re: lsvtec
 

I'd have to dissagree with the unreliability factor... I've built quite a few now and as long as your not cheap on parts(ie. no ARP rod bolts)it'll last just as long as any other motor, even NA with a few bolt on's you can hit tall 13's in a fat 6th gen civic ;). As far as compared to boostin... build an ls/vtec, and boost that. It will definately move!

Re: lsvtec
 

what i was wondering is what type of head i should use because i already have the the block.....so that should be a easyer to answer

Re: lsvtec
 

any b series head b16 gsr..

Re: lsvtec
 

vtak head i mean

Re: lsvtec
 

b16 it flows alot better.

Re: lsvtec
 

b16 head with some type rrrrrrrrr cams. i woulda done it if i had the cash, but im rocking gsr cams in my b16 head currently

Re: lsvtec
 

i also had questions on reliability .... cuz i have read many threads that they are not reliable....why is that what part of it isnt reliable???weak bottom end..???well im currently getting a b16 head with all b17 cams and valvetrain and ls bottom end with pr3 pistons and rods....would it be reliable as any other ???LMK thanks

Re: lsvtec
 

You might have more experinece thean me, but im just telling from my exper. I had a lsvtec with b18b bottom end. ctr pistons, eagle rods, arp rod bolts, arp head sutds, GE conversion, Gsr Head, with valvejob done, after 5000 miles, head was cracked, rings toasted, and a spun bearing. But other peoples lick my vary

Re: lsvtec
 

ill be hitting 9000k on my LS-vtec and its seen nothing but boost from day one.

As the rest of the guys have said, as long as its built correctly, it will be fine. And yes they do move good under boost.

ppl forget that the LS oil pumps tends to have a little less flow compared to a vtec oil pump. make sure you put a b16,gsr, type r or B20 oil pump on and you will be fine..

also as others have said, run the B16 over the gsr head. Its a better flowing head and easier to find aftermarket intake manifolds for and you dont have to worry about the secondary butterflies.

Re: lsvtec
 

I dont know where you get that?

I saw a thread on HT where GSR and B16 flow charts were overlaid, same ones Alaniz has been passing out for yers to show there is no difference in flow stock for stock, they looked like the exact same goddamn curve, but the B16 made 1 whole cfm more than the GSR for a short period... still looked exactly like the same goddamn curve... and two or three people made comments to the effect that OMG B16 V-TECH FLOWS JDM BETTER!!!11

::)

GSR has a better intake port entry, drops straight down onto the valves. Squared combustion chamber, with actual honest to god useable QUENCH PADS!!11. So, even if the head flow is 0.0000000001% OMG JDM LESS, the actual head itself performs better. Which is why you should definitely get a B16 head, they are more JDM.

Re: lsvtec
 

the truth of the matter is... B18C1 (GSR) head's do infact flow BETTER than a B16. It's just that the only intake manifold you can run on a GSR head is the GSR intake manifold, which infact suck's compared to the B16's. The GSR has larger ports and in some cases better cams, however the B16 intake mani. has a better design... that's why GSR's make good torque(a trend seems to be that the gay'r the flow, the better the torque. The better the flow, the better the HP.)and the B16 is a Top End screamer! If you do an ls/vtec and use the factory rod's, put in ARP rod bolts. ARP head studs are a must, and DEFINATELY a VTEC oil pump, or as mention'd that of a B20's(as a side note, I'm not 'sure' about this but I believe if you ask a Honda Technician, any B18 from 96+ flowed the same psi as a B16/B18C/B20 models oil pump's....... Moral of the story, don't be a cheap bastard and it should last a while!

Re: lsvtec
 

hhaha jd said v-tech haha, honestly ive never heard any difference between which head u use. but then again what would i know i just buy stuff based on how cool it sounds :P

Re: lsvtec
 

Well, if you want misaligned ports, you can run Skank2. AEBS Typhoon is $160-170 if you look around, and has the correct port entry. Edelbrock. Buncha custom sheet metal one-off racer types units. So... can only run GSR mani?

That's been a myth for quite some time. Never seen a stock rod bolt fail on a stock Honduh B-series rod, correctly torqued. They break across the beam due to fatigue before the rod bolt lets go.

Re: lsvtec
 

How much does a stock GSR or B16 head flow?Ive never seen the actual numbers.

Re: lsvtec
 

I bet the reason why everyone says that they are unreliable is because the person doing the work sucks balls at doing engine work. My guess is that it was their first time rebuilding an engine and didn't do everything they should have. Thats why ls/vtec's have a bad rep. My point is how many engines did they build before this. If you do everything by the book I think that you should be fine.

Re: lsvtec
 

I've kinda been wondering the same things though with ls/vtec setups. I don't mean to try and thread jack here, but i've helped a few of my friends build em, and now that i finally got my ls i've been thinking more and more about doing one. I've seen some really nice ls/vtec's that have lasted a decent while, and then i've also seen some really shitty ones that have lasted only a week. Originally i was gonna boost the ls in my ED hatch, but after reading about how shitty the heads flow on a stock ls, i've been wondering if i should even waste my time anymore. Honestly this is a street-driven car, and i'm not looking to make anything over the 300hp mark anyway. For where i live it would just be plain un-drivable. I know best bang for the buck would be the turbo, but i just don't know if i want to go through all the hassle of one again.

Re: lsvtec
 

so then a gsr head and a ls bottom head conversion...is a good deal with some aftermarket rods and head bolts...??would stock pr3 pistons be cool...? what else would i have to buy ...aftermarket wise....lmk..peaz
