LsVtec? or just LS...
 

Alright I've decided to keep my 1993 civic si hatch, and toss in a LS (94 B18B).

The reason i'm choosing the 94 is because mines a 93, and i dont want to get an older engine, unless it's the same generation.

I'm just deciding on whether or not to make it an ls/vtec. I plan on boosting and want to reach a range of 300 horses safely, and quickly as i plan to strip race mildly. Maybe a little more depending on how easy it is to drive at that point. I think I would have a shop confgure the head to fit unless it really isnt that hard.

I'm working withan estimated 8,000 budget but that inlcudes my paint, suspension, wheels etc, which i plan to do all myself. So about 3000 on the engine, which includes everything to swap and boost. I've loooked on here but theres so much different info if someone could point me in the right direction thatd be great.

And what would be easier, buying a whole LS complete swap, or buying the block and axles seperately, i'm not sure what i would need to update at that point aside, the internals which i would do anyway.

Also if anyone knows a place that makes parts specifically for this setup or just boosted ls setup thatd be sweet too!

Re: LsVtec? or just LS...
 

you can reach 300 on a stock ls boosted and be alright with a good tune so theres no need to go ls/vtec. besides the point to a ls/vtec is to put in somthing like p30 pistons and get a bad ass n/a motor. so just put in the motor and boost the hell out of it.

Re: LsVtec? or just LS...
 

Don't be an idiot... go with the vtec head.

Re: LsVtec? or just LS...
 

Okay I'm a jackass, I think i'm going to buy a 96 DX coupe because of the extensive repair id have to do to get the 93 hatch to look good again. Would the boosted LS still be a good swap and would it still have a compatible OBD? Is there any info behind swapping an LS into a 96-98 dx?

And so i shouldn't need a vtec head to achieve a 300hp and a little higher numbers?
I'm not sure if the newer civics weigh more than the older ones.

Re: LsVtec? or just LS...
 

god help you

Re: LsVtec? or just LS...
 

Vtec is ------- lame. 300 should be just fine, if you want more just port the head, throw some upgraded valvetrain and some Crower 404's

You'll be fine on the swap and the OBD.

Re: LsVtec? or just LS...
 

If you call more power and a good powerband lame? Then I guess vtec is lame. Come on guys, we all know LS motors make ---- for power compared to an LS/Vtec. The LS powerband starts at about 5,000rpms and starts dropping like a rock around 5,300 rpms. The powerband of an LS/Vtec head will start about 5,000rpms and climb until redline. Seriously though you will probably gain about 50whp just for swapping in a vtec head.

Re: LsVtec? or just LS...
 

lsvtec is the ----, althoug mine lasted a mere 2 weeks due to my own stupidity, i loved it for the 1200 miles i rode the ---- out of it, just walked on my buddies stock gsr all over the place.

Re: LsVtec? or just LS...
 

yea def.ly use a vtec head to expend the power band, it`s not just the horse power that helps but also what rpm does the power extend up to.
Or do it the cheap way, go with a set of higher lift/duration cams.

Re: LsVtec? or just LS...
 

with the money you are going to use to do a ls/vtec the ''right'' way towards a boosted ls will walk on the lsvtec all day.

Re: LsVtec? or just LS...
 

Stock for stock, the vtec head flows a lot more air. I still like to make torque and not have to rev the piss out of my motors to make that torque.

Re: LsVtec? or just LS...
 

A turbo will give you more torque than your car will be able to handle. If you like torque get a RWD V8 with big fatty tires.

Re: LsVtec? or just LS...
 

+ Boost = oh god!! :y

Re: LsVtec? or just LS...
 

Plan for 300 on the boosted ls then when you get used to that slap the vtec head on it and get even more out of it.

Re: LsVtec? or just LS...
 

then you would have to retune ::) so if you want lsvtec turbo then put the head on first make sure it runs ok and then boost the bitch and call it a day.

---- vtec O0

Re: LsVtec? or just LS...
 

If he would have had a stock TypeR head w/stock itr cams on their he probably would have made an extra 50-100whp and also had a better powerband.

Re: LsVtec? or just LS...
 

im running ls turbo right now, high 12's. if i had a vtec head it would be low 12's. get the vtec head

Re: LsVtec? or just LS...
 

Where was that thread arguing over LS/Type aRrr heads a few weeks back? The powerband of the Non Vtec vs the Vtec was sick..

Re: LsVtec? or just LS...
 

it doesnt matter what you say, the same ignorant people will always say

Re: LsVtec? or just LS...

Yeah, show me a similar setup using a stock type r head with stock itr cams that makes 50-100whp more than this and a better powerband ::)

Or just get real cams

Re: LsVtec? or just LS...
 

no i would rather get the head that can flow the air that real cams would need. plus revving past 7k on an ls is always a crap shoot even on a built head, its not meant to be revved high just by the design.

Re: LsVtec? or just LS...
 

care to show me one ounce of proof?

i take my p75 head over 7k every day...

look im the first one to point out the disadvantages if non vtec motors but i just get sick of people spouting off bullshit that they are basically making up. if you want to rev a non vtec head to 10k you can it just needs some mechanical work to be done. not many people rev that high though on the street and in street form they work just fine to 8k. they have the same port shape as a b16 head and can be ported to flow ALOT better than stock. they can also accept oversized intake valves even up to 33mm. ---- my b20 non vtec head im putting on in a couple weeks has 33mm intake valves stock.

people dont mess with non-vtec cause its just easier to bolt on a BETTER vtec head on but it doesnt mean you cant use non vtec.

Re: LsVtec? or just LS...
 

Exactly.

Re: LsVtec? or just LS...
 

Eh, it seems to be that it's more of a OMFG VTAAAKKKK hype. I'm not saying a vtec head is bad, it will be better than an ls head no matter what. I'm just saying that people shouldn't think the LS head is ----, since people can make just as much power on it.

Re: LsVtec? or just LS...
 

Stock for stock there is no comparison... Vtec head > LS head. To get an LS head working as well as a vtec head you will have to drop a bunch of money into it. It's just easiser to bolt the vtec head on. For most of us that is all you need. Look at the people here at HMT that have dynoed there LS motors, ---- I made more power than they did. Drop a vtec head on and you got a good 50whp more right out of the box.

Re: LsVtec? or just LS...
 

Yup, I'm agreeing with you.

Stock for stock, vtec is better. There's no question about that. If you're going all out and building it, I would say go LS, port it, big cams and be different.

Re: LsVtec? or just LS...
 

LS, love the torque, and with some ecent cams you should be doing pretty good.

Re: LsVtec? or just LS...
 

what makes me laugh is people like you. Have you tooke the time to look @ a LS head? Have you seen how the rocker system works? LS's use floating rockers, there is really nothing securing them to the head. if you take off the cams they just fall out. Not only that they are prone to breaking.I work on a 11 second LS crx everyweekend, we are tired of the rockers breaking from revving it to 7.5k so we are sending them out to be cryo treated. Bottom line the head is not designed to rev high, should you could spin it high but like i said its a crap shoot.

Re: LsVtec? or just LS...
 

LS + Boost = POWER!

Re: LsVtec? or just LS...
 

I agree go with a vtec head, When i built my LS i biult the LS head and should have put the money towards a si head, But if you wanna run a LS head PM me i'll sell you my built one.

Re: LsVtec? or just LS...
 

I heard the LS was the official motor for Brokeback Mountain.

Re: LsVtec? or just LS...
 

Vtec DOHC Head = $500.....LS Head= almost Free...LS Head + $500= Vtec head

I agree the Vtec head is alot better stock to stock...and yea you can say put that $500 into the vtec head and it will be uber times better yea thats true but for a budget build it really comes down to how much you want to spend...I honestly would rather put the $500(cost of head) + about another $200-$300 to do and LS/Vetec properly into building an LS head, not to rev high but to flow better...but there is the difference if you want to make 500hp+ get a Vtec head if not an LS motor could get you close to 500

Re: LsVtec? or just LS...
 

lol, you just call me gay... bastard

Re: LsVtec? or just LS...
 

BBKA, I'm sure you've seen the 295 whp stock block ls motor with the crane turbo cams. 9 psi at that, too O0

Jeff Evans tuned it, and it made a hella fat powerband.

Re: LsVtec? or just LS...
 

well this thread has gone the way of every other vtec/non vtec thread. have i ever seen a LS head, yeah i have 2 in my basement, and one on my car. point is for me to do a vtec conversion would cost alot more. sometimes its easier to fix the problems with the non vtec head.

regarding the rockers look up "rocker arm stopper" by tomei or HKS for the sr20 motor.....

stock for stock yes vtec better but if your going to port the vtec head add aftermarket vavles/valvesprings and add cams then its kinda a moot point isnt it. your adding aftermarket parts to most of the advantages it had. its cheaper to work on LS heads when your going to do lots of other work anyway. theres not going to be a huge difference in a LS head thats been ported with oversized vavles and better valvetrain with a mechanical rocker arm stopper compared to a vtec head with the same mods.

Re: LsVtec? or just LS...
 

i just wish people wouldnt talk so much ---- about the non vtec head. its more work but it doenst mean its a horrible decision. try, just try to be open minded and let people make decisions on their own not tell them they are stupid or gay for not doing what you are doing. give people pros and cons and let them make up there own mind. i think its amazing especially when d series people are the ones dissing on LS motors... you dont see me saying WTF d series is gay do you. of any site i would expect HMT to be more open since its a low budget site and the LS fits that bill. you can throw in a set of cams and valvesprings for less than youll pay for a vtec head alone and it WILL make comperable power so a stock LSvtec

That powerband sucks ass lol. You get maybe 2,000rpms at most.

Here is a good powerband (3,500 rpms)... http://forums.evans-tuning.com/viewtopic.php?t=2993
This is a stock GSR head too! Very simple setup and look at the results.

I think this is the car your talknig about... http://forums.evans-tuning.com/viewtopic.php?t=790
Can't see the dyno sheet though.

Re: LsVtec? or just LS...
 

wow thats a great comparison since the LS has stock cams and the GSR has crower turbo cams. find one with a stock vtec head and a stock LS head that has cams with the same turbo.
