I just bought an Integra LS, and have thousands of questions!

I just had some Qs about the car. I want to put a V-TEC head on the block, and was woundering wich head to use, GSR, or TYPE-R? Also, will I gain any HP with the new head?

Yes, you'll gain hp. The conversion is called ls/vtec and is pretty popular. Do a search for the ups and downs of it, as it's been discussed in detail both here and in the engine swap forums. You can use a b16, gsr, or (I think) type r head. Assuming the ITR head will fit (I think it will), it should flow the best, but it will be expensive. The GSR head flows a little bit better than the b16, but it's a lot more expensive and more rare, so I'd just go with the b16. With a basic untuned ls/vtec with the stock ls internals, you should put down 140-150 whp. Of course, as long as you're taking the motor apart, and if you're going NA, you can put higher compression pistons in it (gsr or ITR) and better cams.

I think the CTR (Civic Type R)head is the best to use for the conversion. At least thats what I've heard. You will gain a boat load of HP with the LS/VTEC though. SpaceMan is right though, the B16 head is easier to come by and wont cost nearly as much (will still make good HP though)............fISH

i always heard that the B16 head flows better than the GSR's head. One of my friends who owns a shop has a turbo'd CRV/VTEC engine in his car. he's running a B16 head. The best he ran was a 10.5 in the quarter mile with 30 lbs of boost and a 100 shot. this is also his daily driven car. the car's a beast!

Hey Guys I Heard That Ls Vtec Dont' Last Aslong, Plus They Can Have Problem Like Leaking Oil, If Not Done Properly, Plus It Cost A Grip. Isn't It Better To Do A Gsr Or Type R Swap, Or Better Yet Add A Turbo? I've Seen A Tyte Ass Gsr With Turbo, I Like The Vtec And Turbo Mix. It Look Like Its Fast, But Can I Get A Ls Turbo Be Quick As A Gsr Turbo?

Holla Back Yo

can you not capitalixze every damn word. also no it doesnt cost a grip, the price of the head/ecu (4-600 if you look around, maybe cheaper) plus about 150 bucks. to boost it costs WAY more and a GSR or ITR swap is more money . and Id figure the LSVTEC could take as much if not more boost later on that either B18C cuz of lower compresion. they last fine if you did it right to where it down leak oil and you let it go dry, also cant drive the piss outta it, as with any engine it will wear much quicker like that. and it wont leak oil if you take your time on the oil lines.

Is it better if i get a vtec head and a turbo? Or just a ls turbo, or a new whole gsr engine with turbo? What will be quick and "last long"?


B18ls how u know thats a fact that b16 head is the best to work with, maybe the cheapest and convenient. Can it hang with the gsr or itr?

well, the heads flow almost identical, ive seen the benchflow results. the B16 is better because GSR manifold has to stay on GSR but the B16 can use stock or the ITR manifold. the B16s manifold flows better at high rpms cuz the runners have less surface area.

oh, also all 3 will be quick, Id say LS turbo would last longest sinc its most turbo friendly with its lower cr, plus the trannies good for it too.

The ls/vtec is a great combo, but only if it's done right. It could cost you as much as $2500 to do right. I suggest the b16 head because it's easy to come by. The head you use wont make a big diff. Keep in mind, a vtec head is going rev to 8k rpm's easy, but the ls bottom isn't made to handle that many rotations per minute (rpm's). That's a problem! This is why I said it can cost about 2500. The bottom end must be built up too. There is alot more to it than slapping a vtec head on and rerunning the oil lines. I wont pretend to know everything about the conversion, but I know you my fair share.

You can turbo an ls/vtec, but why? If your going turbo, just do a ls/turbo. My 2cents.

becuase a LSVTEC turbo and a LS turbo on the same boost, the LSVTEC has more power. And you dont have to build the bottom end up, the r/s ratio is only 1.54 to the B18C's 1.58 so its almost the same. only difference is that it doesnt have oil squirters. and oil lines are 100 bucks, Ive seen the dual sized dowels for no drilling but not sure the cost, probably not too much. oil line kit I think exen comes with the plug and a tap is about 5 or 6 bucks at most.

then you can get the head and ecu and other misc parts you need off ebay or where ever. if you get the dual sized dowels thered be no way you could mess up the placement of the head, and when you tap the threads for the plug make sure no metal shavings stay in the hole, oil lines take your time and make sure all the fittings dont leak and assemble it all and your basically set. the reason I think most peoples dont last long is they build it and then go sit at 8k all the time hossing it all day and it wears uot quick.

I got my civic and every day I was between 4-7k redlining every shift and pretty soon I dont got much ciompressiopnand im blowing smoke and got no power anymore.

if youre worried about the block then get a girdle, have no clue what that runs though, but I still say you dont need 2500 bucks, otherwise why would you ever do that when a GSR long block is only 1800 bucks.

so can a ls turbo or ls/vtec can pass the legal smog test? Will the cop f*ck with me and harrass me for it? Will i have to report my modifys to my insurance co?

as far as I know you dont have to report modifications but when you wreck the car comp/collision will not pay for what you have done cuz you dont have it covered, just the car itself.

and for smog I think it should, if you have it tuned right.

hey spaceman a stock ls has about 140hp stock!

hey spaceman a stock ls has about 140hp stock!

not 140whp

.....

uhhh how much hp does a stock ls have then smart guy???

uhhh how much hp does a stock ls have then smart guy???

140 at the flywheel....like 115 at the wheels mr. fast and furious.

140 at the flywheel....like 115 at the wheels mr. fast and furious.


uhhh yeah 140....pooped out 93 was just referring to the stock specs of an ls which is 140...so u dont need to correct him with your "at the wheels" shit cuz nobody refers to that when they talk about hp

so a type r has 195 hp at the flywheel....is that like 152.945865368 hp at the wheels?

uhhh yeah 140....pooped out 93 was just referring to the stock specs of an ls which is 140...so u dont need to correct him with your "at the wheels" shit cuz nobody refers to that when they talk about hp




actually if you look back on page one what pooped out quoted:

and then what he said:

you'd know why kevin wrote what he did.

good job kevin on bringing back an old thread. the original guy doesn't even come here anymore. its been two months since he posted. and almost a month since the last post. check the last post date before replying. and around here if we say "hp" we mean at the crank and "whp" at the wheels. so in your first quote you had "140hp" watch what you quote.

thanks for trying though.

my bad kevin, i did not see that pooped out 93 was at the bottom of page one. damn new related links section. thing takes up too much space.

that was hella funny tho between powered_by_acura and kevin lmao

uhhh yeah 140....pooped out 93 was just referring to the stock specs of an ls which is 140...so u dont need to correct him with your "at the wheels" shit cuz nobody refers to that when they talk about hp

so a type r has 195 hp at the flywheel....is that like 152.945865368 hp at the wheels?

you're an idiot

everybody talks about how much hp you get to the wheels more than what you have at the flywheel. What you get to the wheels is whats important

ok tony montana from the panama

pooped out was refering to the flywheel hp which is 140
kevin corrected him cuz he thought pooped out was refering to the wheel hp (its just a misunderstanding, he's probably correct about the 115 at the wheel though)
everything is worked out and this thread is dead so would u do all of us a big favor and shut the fuck up mr. i wanna be an italian mobster

im not trying to jump on eithers side, but I posted it earlier and maybe it got overlooked.

spaceman spiff made a post and included this phrase in there.

"With a basic untuned ls/vtec with the stock ls internals, you should put down 140-150 whp."

then pooped out 93 replied to that with quote

"hey spaceman a stock ls has about 140hp stock!"


spaceman clearly said 140WHP out of LSVTEC and then pooped out tells him its already got 140 stock. so I come to the conclusion he was referring to WHP just like spaceman or why quote his post when referring to the power rating in the post and the specific member who posted

ok tony montana from the panama


everything is worked out and this thread is dead so would u do all of us a big favor and shut the fuck up mr. i wanna be an italian mobster

an dont tell me to shut the fuck up you fast and furious fan boy... i didnt realize this thread was old an done with
