ls port&polish

what would be better, to port and polish the stock ls head or get a type r head?

it depends on what you are tring to do. Turbo,nitrous,supercharger,all motor?

it depends on what you are tring to do. Turbo,nitrous,supercharger,all motor?trying to go all motor

then you want the type r head

if you are going to go through the trouble of port and polish, you might as well go the whole way and get the type r. that is what i think i am going to do.

N/A, turbo, nitrous, blower, whatever you want to do the ITR/B16 head is better than the LS. It flows better out of the box, flows more ported, and makes more power. And if anyone says go LS head if you go turbo because of overlap, shut up. If LS heads were so good for turbo how come an LS/Vtec turbo makes a boat load more power than an LS turbo? It ain't because of half a point more compression.

$$$! :screwy: :screwy: :screwy:

the reason turbo LS/VTECs make more power than a Turbo LS is because of the VTEC....think about it.....think about it.....did it set in yet? and yes if you're going allmotor just go ahead and do the LS/VTEC but use the B16 head. you'll save a ton of money.

this is a newbie post. u have been here long enough. you should know this by now. valve overlap is the reason why people do not like vtec with their turbo applications. compression is almost irrelevant. notice i said ALMOST. even if u change out the cams completely in the gsr, the ls has more potential. i will not go into other reasons why the ls is chosen over the gsr for FI. this has been argued over and over again in many posts. do a search beofre you make such a stupid response.

my previous post applies to u also. you should know better about valve overlap. to boost a lot-your cams need to have a high lift and short duration. for good NA apps-you would like medium lift and a very long duration. wow, and i used to respect you.

Please oh Mr. Honda God, enlighten us HOW the LS is better. The head flows less, and has less potential to flow while ported. That's a fact. Having vtec lets you run more duration and lift up top (where overlap is NOT AN ISSUE BECAUSE THE MOTOR IS SPINNING FAST ENOUGH THAT HAVING SOME OVERLAP IS NOT GOING TO UNLOAD THE TURBO!!! :banghead:) to make more power but run a lower duration and lift profile for the low end so you still have enough power to drive around for a street car. Most full out race hondas are probably launching at 6000+ RPM's and would be running the vtec lobe permanently, but does that means they're going to the LS heads or LS blocks because they're better? No.

If you think you're the king shit when it comes to cams, keep thinking that. Call ANYBODY that makes turbo cams for ANY car and none of them will tell you that a very low duration cam is bad. Yes, overlap is bad, but there are other factors much more relevant to how much power your motor is going to make other than overlap. Call ANY reputable cam grinder that has been in the business long and has ground lots of turbo cams before, ask them what they think. They arn't going to grind you a 190/190 @ .050 .650/.650 lift cam because that would make fuck all for power. Call up cammotion 225 9266110 in louisiana, they'be been grinding cams for ever, ask them what they think. Call up murillo, bennett, holcomb, call up ANYBODY who has been in the turbo business for a while and see what they think.

Hello jspit21,

It looks as if you've started another good old fashioned Honda cat-fight. Meeoww. Let's start at the begining, how much do you want to spend and what do you want your car to do?

Hello jspit21,

It looks as if you've started another good old fashioned Honda cat-fight. Meeoww. Let's start at the begining, how much do you want to spend and what do you want your car to do? I'm thinking of spendind around 3000 within the year. I didn't know if it would just be better to buy a turbo or to change my car to a manual. Would my car not be that much faster with a turbo because its an automatic or is it just the fact that the manual is more efficient

I would do one of two thing I would either sell the car before you out any money into it and buy a manual or go ahead and do the manual conversion. I think you will come out cheaper just selling the car and buying a manual. Then go from there. If you feel you have to have VTEC then buy a GSR if not the buy a LS. simple as that. Now I would suggest the LS if you are trying to keep a
$3K limit. B/c for $3k with the GSR you will be boosting 6-8psi and the LS you will be boosting 8-12psi, b/c with $3K you won't have enough money to build either motor's bottem end, and the LSwill be faster stock for stock. But the GSR will be fast and the turbo will work fine on it but you won't be seeing as mich boost as with the LS. Also LS/Vtec engines have to be done exactlly right when you are trying to boost them or bad things will happen. If you cannot find a reputable shop that has fdone lots of thesse and had no complaints then go for it but it is more risky and not really worth it IMO you are only getting a little more dispalcement with LS/VTEC so it does not out weigh the risk IMO:2cents:

i did do some research, and if i may, i retract the statement about the duration :banghead: the lift statement will stand though. you are quite educated, although i will not dismiss my response completely. this is a stupid argument-it is been covered many times and they always have the same outcome. u do win the argument with me, but i have always seen LS blocks and heads run faster than their vtec siblings.

:iagree: 100%.

boosted an kitted, plz settle it in PM's...lets keep the teg forums at peace.

when i made my smart ass statement i was replying to boosted's comment about ls/vtec making more power. i was being a smart ass because its obvious an ls/vtec would make more power over an ls and comparing a vtec head to a ls head is like apples and oranges. yeah one is better and theres an obvious reason why sorry should have quoted was not responding to the person who originally posted this thread. :banghead:

sorry everyone, i am in a bad mood today. tough day at work

OK, now that that's settled. At the risk of sounding ignorant I'd like to know the actual reason behind the cams needing to be this or that for FI or NA. In NA, medium lift and long duration would create a better vacuum? for better exiting of the exhaust gases right, and entering of the intake gases? FI needs large lift with short duration because that would create more pressure at faster speeds to spin the turbine quicker?
Just curious.

Hello JSpit21,

It appears that you are looking for a reliable car with pretty good performance. Converting an automatic transmission to a manual transmission may cause conflict with your insurance company because your V.I.N. will not match the cars original configuration. Engine work can get expensive, and depending on how emotionally attached you are to your car, you may not feel that the cost is justified. The simplest solution is to sell your current vehicle and replace it with a vehicle with more displacement and a manual transmission. If you prefer automatic transmissions, I highly recommend a 6 cylinder engine. Dollar for dollar, larger displacement is the way to go. There's no shame in driving a used luxury car.
