The b16 is usually said to flow better and the GSR has i believe a .3 higher compression, it really comes down to a personal choice of which head to use. Personally for a NA build I would go with the GSR head, but as I said,its a personal choice and there will be plenty of people who will tell you to got with the b16 head

 

what reasons are there for either option? I don't really understand the flow/compression stuff as far as what it means and how to decide...

Are you going to work the head over prior to slapping it on or just put it on as is? If you are really going to work it over with a P&P and what not then it doesn't matter because in the end they would all be the same if you did the same work both of them.

 

there is a sticky on here about LSVtec that i can think off the top of my head that tlaks about the differences, look that sticky up

 

gsr / b16 flow is basically the same..
GSR will create more compression..

 

sticky? how do I find it and why would I be looking at LSVTEC info for what I'm wanting to do?

 

how does compression factor in (please explain in depth) and what are reasons to have the higher comp.?

Alot of people dont fully understand compression..
Its 1 part of 100 different ones that effect your power output, People say you gotta have a certain amount of compression to run a cam.. Maybe to have the FULL effect of that cam you do, but you can put pro3's in a b16 and make power.. the power will not be where you want it, and probably wont come on till about 6 k and u wont max it out until 10/11k or so. But you get the idea..

a high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air-fuel mixture due to its higher thermal efficiency. High ratios place the available oxygen and fuel molecules into a reduced space along with the adiabatic heat of compression - causing better mixing and evaporation of the fuel.

It has alot to do with the combustion process and how much timing you can run in the end..

 

I actually already have the B16A2 head, but am open to selling it and getting a GSR head if that would be better...

the B16A2 head already has S2 valves, springs and retainers in it (which could be transfered over to a GSR head) + I have a set of S2 Pro 1 cams, IM (not pro), 68mm TB, composite fuel rail, and planning on getting S2 Pro titanium gears. also, planning on getting the p&p done and whatever other machine shop work that would be good to get both to the head and the block. I really wanna build it up right. I just gotta find out how, etc.

Your well on your way..
If you have all that stuff already no need to switch over to a GSR head..
Mill your head slightly, and resurface your block and runn eithe ra 2/3 layer HG and you should be good to go compression wise.. Your well on your way, i'd do what you can do with the head first.. then worry about the block..

what does that all mean? would you mind explaining in more depth?

thanks-

Brett

 

btw, both the head and the block still need parts. I need a distributor, ECU (maybe hondata or a S2 chip) - I don't know what else. the block is bare - not even an oil pan (got it off of another guy on here). I was thinking about getting the block sleeved and using eagle/wiseco parts to finish it out - kinda like a poorman's type r or something - whatever would make the most out of the build.

 

You sound like you just need to do alot more research about how an engine works in general. Once you understand these basic concepts, you will be able to make an educated, informed decision without creating a thread and having everyone explain everything , step by step to you. (Which has been done before, countless times.)

Some good refarance material for the beginning engine builder...
http://www.amazon.com/Engine-B...r=8-1
http://www.amazon.com/Reher-Mo...r=1-1
http://www.amazon.com/Performa...r=1-5

Those 3 should get you a nice start on this "hobby". I made a thread a while back that should also help answer the question you initially created this thread for.

You have a LS block and are going to put a VTEC head, so you are really doing a LSVTEC build. I believe the sticky is in the all motor section. It will tell you how to put the engine together and it will also explain to you the differences in the two heads.

 

the block is a B18C1. is that not a VTEC block?

 

thanks, Comb. Contraption!

I'm still learning my way around this site and am not that good at finding what I'm looking for yet. so far I've just used the for sale forum and am not sure exactly what terms to use in finding other info such as what I made this thread for. I realize some people on the tech sites would prefer people to read what's already been explained before. It's knowing how to find it that's the hard part.

 

The B18C1 is a VTEC block and it comes with a GSR head. In your first post u said something about putting a 90 Integra LS in a hatch so I didnt know you had a GSR already, but the people before me already have said the differences between the two heads, and if you want a little more comparison then look at what i said before. Here is the link- https://honda-tech.com/zerothread/1676914

Agreed....

The number of posts like this springing up in this forum and the bad responses going with it, is scary lately...


There really should be some sort of "test" of basics that a person must be able to pass in order to be able to post in this (and a few other) sections. Some might consider this idea "elitist" but in reality, it forces people to do more reading in forums where they're not able to post when they want info. It also prevents people from asking such basic questions in a forum where the answers they get will be completely over their head and outside their comprehension anyway.

I'm just thinking out loud I guess but it's like some guy showing up at the airport saying "I'm ready to fly that jet plane over there, I have no experience but can you just walk me through it?" Where do you even start....? The short answer is you don't and nobody should be trying to fly anything without some basic USEFUL knowledge.

Others have said this before but I'm saying it again, hopefully before the last few knowledgeable people on this forum get fed up and leave, the search function becomes pointless as no one is willing to use it and the blind leading the blind will rule.

btlancaster The best answer anyone has given you so far is to READ and do some learning and research on what you want to do. Follow the links posted above and really use the search function as their's a ton of information available to you in this forum if you're willing to take the time to look for it.

Good luck

 

what I had said re: my '90 LS is that's just the car I'm using to put what I'm trying to build in when it's done.

 

thanks - 00Red_SiR...I hear ya

you know, the thing that sucks is that there just aren't many guys in my area to actually hang out with and learn from in person. so, though these are great forums, my main resources are this site and g2ic.com

Understood. It's good that you want to learn about this stuff but you have to keep in mind that it takes a while to gain valuable knowledge and you have to be willing to put in that time. That time you will put in comes in the form of reading...lots and lots of reading. The more you do, the faster you'll gain some knowledge and the more specific your questions will be. Then when you get some answers, you'll have acquired enough basic knowledge to know if you're getting good info or bad and still be able to make up your own mind.

Use these sites the way they were intended...as a research/reading resource for you to learn. After you learn, you start asking questions and you'll find you'll need to ask fewer but more specific ones.
