i have a ls which has about 120k im thinking about going ls vtec with the si(b16) head. i heard the conversion is pretty easy now with the golden eagle vtec conversoin kit. has anyone ever used this and encounter a problem? would it be fine to just slap on the si head on to my block with the conversion kit? what should i do before installation? i know some people do 3 angle valve shop but what else should i do before installation.?

 

before installation, ummmm use the search

does anyone have problems with their ls vtec?

 

bump

 

i know we're not supposed to say this, but ls/vtec gets talked about every day, you need to search. There's plenty of testimonials of people with their ls/vtecs, some good, some bad. You need to figure out why you want it, what you want out of your car, and if it's worth it to you. I'd recommend having a pretty good knowledge of your car so you can work on it.

Beyond slapping a head on, i'd recommend ARP rod bolts, eagle h-beam rods, b16 pistons, maybe a sleeved block, and hondata.

 

if you plan on reving past 7k u need to build that bottom end for higher revs, ie get the crank balanced, eagle h beams would be a good idea, if it were me i would build that motor to rev to about 9500

 

I've been doing research on the LS/Vtec swap myself. Theres lots and lots of info on it and I got it all off of the net and a lil from books.

In short, this is what I've learned.
You really need to have a good idea of the following:
What cams?
Tuning device?
Where do you want the HP?
Redline?
How much HP?
Driveability?
Reliability?
¼ mile time?
Powerband?
$$$$ how much to spend?$$$$

Heres a lil parts list that I'm WORKING ON (not final by no means and it's probably incomplete):

àB16A Head assembly (Fuel rails, Dizzy, ect): $475
àITR Pistons/rings: $190
à Balance and Shot Peene: 200
àGolden Eagle LS/Vtec conversion parts: $249
àGSR water pump/timing belt: $79
àGSR Oil pump: $80
àAEM Cam gears: $115
VTEC B-series distributor $125.00
GSR Rod Bolts: $45.00
-----------$1558.00----------

àHondata S100: $250
àITR Clutch: $150
àPrelude 270cc injectors: $120
àWalbro fuel pump: $100
àB&M fuel pressure regulator: $50
-------------$670.00--------
Total-----2228.00-----

Not exactly cheap is it? And you can definetly spend more q/a block girdle, having more machine work done to the crank, getting aftermarket rods, head and deck milled.. ect ect. You can spend several thousand EASY doing this.

Next up, web sites to peruse and learn from.

good good info
http://www.team-integra.net/fo...11889

Some of those links don't work, but I havn't weeded them out yet.
I can honestly say, this is everything that I found in about 5 hours, just by searching. I should have been compiling this info from when I started :S

You definetly need to check out http://www.team-integra.com. They have lots ogf good info about the r/s ratio and even have a couple of write ups about the LS/Vtec.

When I decide what I'm gonna do as far as my own LS/Vtec swap, I'm going to orginize all the info I'll have by then, and I'll make a real nice thread on it. Maybe it can be put in the FAQ or something. Just to help pple like you and me so they have an easier time.

GSR rod bolts wont fit in LS rods. You need ARP rod bolts for the LS rods.
You can modify your LS distributor to work.
Its easier to use B16 pistons because they bolt up to the LS rods without modification. And can yield the same compression your after with R pistons.

 

Is there really a need for a gsr oil pump?

Lets say you had a b20 vtec, the stock oil pump is fine right. What are the advantages of having a gsr oil pump?

if I remember right, after 96 all the B series oil pumps were the same.

Why? Lsvtecs are known to make peak power somewhere around 8200 rpm.

 

the only reason im going ls vtec is because my friend my give me his b16 si head. i am not trying to go all out to see a lotta horsepower difference from it. i could understand why people get cams and ctr pistons and else to make their compression higher, but if i were to spend that much money on it. why not just get a turbo charger? what im really asking is that if i just get a si head on my ls with prob the golden eagle vtec conversion kit with prob gsr or type r ecu, would the car be stable to be driven/race occasionally? i dont relaly see the point of getting new clutch, oil pump, water pump unless its something wrong with it also. why do people get the arp extended head bolts? just curious

 

no one has problems with ls vtec?

 

you can just do a lsvtec with the head, and new GE conversion kit and some new head studs. BUT wont be reliable past 7500k rpm. look at this guys build.

i seen 2 diff guys do tha ls/vtec setup....both of their cars broke down within 5 months... so yea...

 

its kinda like the cheap way and then there is the right way. i would find a b18/b20 block and build that and keep your car running until you are done building that motor the right way. then if something happens you would still have a back up motor to use. just try and think things through and make the best decision for your self.

later

Well, there are many variables that determine where your motor will make power. For example, your CR, what cams you're running, etc. That's a terrible piece of information to spread.

 

mac_24_seven has also given a lot of good information. Before you start tearing into your motor it's always good to do a lot of research. Personally, I researched the build for about 2 years before I even started. That's a little unnecessary though. Also, you need to set a goal for your car. What do you want to do? mac implied this in saying 1/4 mile time...however I feel that's a little too specific. I don't drag race and I'm building my motor/car for road race needs.
