I have already tried to do a search and came up with 1000 "FS:GSR head" posts. I have been involved in imports for years and know my way around them pretty well but most of my knowledge revolves around Civics. I just bought a 95 LS Integra and want to do a VTEC head. I am not sure if I should do a SI head or a GSR head. I also need to know whats involved as far as extra parts needed. Computer, wiring, different bolts, etc. For 2 fairly mechanical guys, is this a 1 day job or a 1 week job? Sorry for all the questions but I will help answer the more basic newbie questions on the board when I can. THANKS!!

 

search for "lsvtec"

 

I have been searching for hours and there is nothing simple like "this is what you need....." If it has been posted before I can not find it for the life of me.

liar!! i just type in ls/vtec and got https://honda-tech.com/zerothread?id=616312 next time, please search first

 

WOW! I can tell you one thing is that I dont like being called a liar! I did search first and I dont really care if you believe me. That is still not the information I want. At the point in time I dont care about Skunk2 cams and ITR valves etc I just want a stock a VTEC head on my LS block. Also, ggangtong81, I plan on being an active member on this board so if this is the way you are DO NOT post replies in ANY of my threads. Is there anyone that can help me in a positive, supportive way? Thanks

 

There is tons of LSVTEC related info here on HT and also go check out http://www.team-integra.net .

As much as you and I both would like to believe that it is a straight across swap, it is not. And this work isnt a DIY sort of job, and it has to be done very well or you will have all sorts of reliablity issues.

 

GSR head and SI B16A head is your preference or whatever you can get a hold of.

Installation is the same, except for GSR secondary intake manifold. You'll have to wire a couple extra wires and need a switch to make it work or use a GSR ECU or you can swap it out for a single stage int man.

If you have all the parts ready on hand before you do the swap and you know how to take off and put on a head. Some can do it in 3 hrs or even less, but if you never done it before, it may take up to 6hrs, unless you run into problems like breaking something or something doesn't come off, but it will not take a week if all you're doing is swapping a head. Very Basic, just swapping heads, rerouting an oil line, tee-ing it on the oil pressure sending unit. Redo dowel seats a head of time and plug the oil port on the bottom of the head ahead of time, just do all the prep and get everything ready and it will only take a 3-6 hours.

I have a GSR head for sale, all ready for LSVTEC. Email me at nwong8@yahoo.com

 

I haven't gone down this road myself but from what I've researched...

Your motor will live or die based on how well the head is machined to match the block. The dowels and the bowls (?) of the cylinders must be matched perfectly. The machine work should only be done by someone that has had their hands in many LSVTEC conversions. I understand that there can also be oil starvation problems since the LS block doesn't have oil squirters.

These engines seem to have a reputation for being about as reliable as a stock block running a bar of boost. (unless they built properly) Just don't make the mistake of thinking it is a simple head swap.

 

Thanks for the intelligent reply. I have continued researching and found a pretty good article I think. I wasnt aware that there was machining that needed to be done. I assumed that it was just a lot of swapping parts. Thanks again!

oil starvation problems!
the squirters have nothing with oil starvation, their job is to keep the piston kool
and lubed.
just to clarify that.

the problem relies on skipping steps on building the ls/vtec.

here are some links that will help you

but unless you are good in building motors or know a reputable shop
go ahead..
