Hi! I'm taking a more attentative stance on the auto culture since my boyfriend and his friends continue to talk more and more about cars.

I have some questions. So this LS/VTEC talk is all about purchasing an Integra LS motor, keeping the block, but taking out the head and replacing it with a VTEC head, like from a B18C or a B16? Am I correct? From reading the other posts, the LS has more torque- is that why people choose to use the LS block? Why don't I ever hear about people using a B16 block with a GSR head?

Also, let's say i drop in a B16A2 into my ek hatch [1999]. The exhaust manifold connects with the downpipe, to the muffler. If i drop the si motor in, and decide to change the exhaust system, would i buy a B16A2 exhaust system application or a hatch application? I would think that i would still purchase a hatchback exhaust system, but having dropped a b16 would change the exhaust manifold size, no? Do you boys know what i'm trying to say?

way cool a chick is into racing and ACTUALLY knows what the fuck she is talking about....

to you !!!

hi. . . first question is that you in the avatar? second question. . . are you hot? . .. third . . . do you need a personal automotive tech?

and a bout the swap question . . . using the b16 manifold and the hatch exhaust is the way to go . . . thena muffler shop may have to make a slight adjustment for you.

Welcome to hondaswap.

Im taking bets on how long it will take before the e-pimping starts.

vpSPOONsol

if that is her in the pic....damn!!

bout the first question, people buy the ls block cause its cheaper, and if they have an ls integ already, even better....

1.8l>1.6l more displacement = more power

Tonyd0821

Im taking bets right now that this thread will go on for AT LEAST 5 pages.....

Any takers?

brc80

If thats her in the pic i know this thread will go at least 5 pages. Wait till everyone else gets to this post. lol

Tonyd0821

thats not her, dont get your pocket-protectors in a quivvel (wow, havent used THAT word in a while....)

im sure its just some anime or movie or other avatar.

i think she should post a pic of herself to let us know what she looks like.....

dohcvtec_accord

Come on guys, at least whore in the Anything Goes forum. Answers the lady's question and don't scare her off. :P

brc80

Pic's, Pic's, Pic's

D See 2

agreed

Tonyd0821

i would have to agree, this thread is USELESS without pics....

dohcvtec_accord

Come on, she's asking a relevant question. Start a thread over in Anything Goes, or else this thread gets it!!

the B16 manifold may be too short to clear the oilpan on the LS block ... i think you might need to use the header for a B18.... and then yes use the exhaust for the hatch and have an exhaust shop fuck with anything that doesnt quite fit right

E_SolSi

and you leg humping bastards wonder why you never see any females on here .... its because as soon as they say hi, 30 of you jump all over their ass

pills_PMD

word.

a b16 block with a gsr head is rather useless. you still have no torque and you have a lower compression ratio due to the size of the combustion chambers...

I am guessing around 7 pages before it gets out of hand, or it just dies and then someone will bring it back to life like all the other relentless threads.

Welcome To Hondaswap, I am the local Ricer.

I would probably say use a b16a2 header, and run a ek hatch exhaust, but you would have to use a muffler shop to make it so it would work exactly because they collector on b16a2 header is different from the stock one.

You guys are funny. Yes, that is me in the pic, although I returned to my natural hair color, black. Dying my hair damages it too much. Are you guys joking when you ask me to post pics for replies?


Ok, so I just posted an hour ago? and I got some replies yay! haha. Thank you for those that replied.

As to the compression ratio... isn't it good to lower compression? Don't aftermarket parts lower the compression ratio? The guy above that talked about the b16 block and b18c head seems to be implying that a lower compression ratio is not good?

I don't think you'll be seeing her again anytime soon, now go get some kleenex and wipe your keyboards off ......bunch of geeks :P

deth101

have the whole thing ,collector and all made custom, 2.5 all the way back to a cheap high flow muffler,pay them extra to weld the cat sheilds onto the straight pipe...done and probably end up cheaper than buying aftermarket exaust parts and paying someone to piece them together.

thats what I'm doing except right off the collector I will have a Y built with a pull chain valve so I can go to straight header from in the car and really scare dorks who rev on me

deth101

as far as compression goes lower for FI,higher for NA....depends on what you want

omega11855

lower compression is good and bad it really depends what you want to do if you want to add forced induction turbo supercharger nitrous then a lower compression ratio would be more suited for what u are doing if you want to go naturally aspirated no turbo supercharger etc then you want high compression so basically it depends what you want

pills_PMD

if you are going naturally aspirated, then you want high compression ratios, as that creates more power...

if you want forced induction, then you want a lower c/r

luVTEC

Higher compression is better for niturally asparated power (no Turbo). If you increase your compression (compress the fuel/air mixture in your cylinder more) you get a larger force on the piston = more Torque.

Lower compression is better if you plan on adding a turbo charger or supercharger becuase you are forcing more air into the cylinder and if you compress it too much then you can cause detonation and damage your engine.


The most common ways to change your engines compression ratio by changing your pistons or changing the thickness of you head gasket.
