I’ve searched,
I hear that if I turbo-charge an ls/vtec, the vtec will be screwed up and all this messed up stuff. But I also hear that you can program your computer to work with it all. How does Ls/v-tec turbo work like that?
can you turbo a vtec motor?
There is a first for everything. I’m trying to fit a Non Vtec head on a VTEC block right now.
I’ve seen alot of turboed vtecs. Its not uncommon.
It does require alittle more testing to make it right but i would suggest turboing a non vtec if want to save alittle money though.
i dunno i like the vtec turbo!! just the power you get from both the turbo and teh vtec would be great… i wanna see a vtec wid supercharger!!!
i have a vtec turbo!!! b16a2 with greddy kit pushing 7 pounds!!! 
im actually selling the car the kit jus got done 2 days ago
Seen it, and driven it. B16A supercharged 94 hatchback. made like 202 to the wheels. It was fast but not as fast as I thought it would be.
Im trying to drive another hatch but my friend wont let me. B16A T3/T4 turbo 325 whp. Stock internals on the B16A and like a Stage 5 clutch. But now he is selling it for $6000. So i dont think I will get a chanceto drive that one.
no, you’d have to supercharge it first in order to turbo charge it, cause the supercharge helps pull in more air so your turbo won’t lag when building boost

Check out that write-up if you are interested in the tech behind the LS/Vtec
and it should be fine boosted…just dont go revving the shit out of it because you have a VTEC head and you think that means you can rev it high like a GSR or ITR…
its been done. kev did it, tegboi.
did you really just type that? my point was that an ls/vtec motor is a normal vtec motor with an external oil line. no other real differance. someone locally had an ls/v-t db8, but now i guess the swap is in his garage?
^correct.
chris = gay.
don’t listen to him. he is nuts, the only reason you “shouldn’t” rev the piss out of a non vtec block is because it doesnt have a main girdle. if chris types something like this you say… “listen here bish, stop comparing pomegranates to apples. try companing an ls bottem end with gsr mains and girdle to a gsr with ls internals and stock girdle. you abuse them equally as much.” then he kicks you in the nuts and says…well my car is quick.
and his reply would be: “If you would have read the article, you would know why.”
It has nothing to do with the lack of girdle, it has to do with the engine’s R/S ratio.
An LS block has an R/S ratio of 1.54:1 while a b16/gsr/itr is closer to 1.75. When you rev the piss out of a motor with a smalled R/S ratio you are putting a LOT of strain on the cylinder walls…
what is a GIRDLE for and when should you upgrade it?
thats bullshit. many gsr’s and itr’s have ls cranks in them and are making good hp and lasting. =) goto the h-t marcus meet this year. i want to show u something.
you don’t really need to, i put one on a b16 i was building for turbo but then i relized i like gsr motors better.
i dunno, i talk outta my ass a lot…i read a couple articles and i think im smart
and yes, i will be at marcus this year
wow talk 'bout hitting the nail on it’s head…i guess i shouldn’t talk tho, you were ls-turbo before me. :hmm:
Thats the primary reason I have stopped posting on this site. xenocron hit the nail right on the head with his answer and you pull out the :bs: flag??? Too many people live off of other peoples coat tails with stories they here on the net. Girdles is to stop movement of the mains with a rod to stroke ratio that can handle higher revs (ie: 8000 +). B16’s don’t come with a girdle because it has the best rod to stroke ratio then all other B series motors with a stock revlimit of 8200rpm. Anyone can through a LS crank into any Bseries motor, but with that crank they are not using the LS rods, they are using a different rod for a better rod to stroke ratio with a different piston size aswell. So if your going to bring that to the table, i think its fair that you mention everything and not make it seem like the rod to stroke ratio is the same as a LS. Remember this is forced induction, not N/A… You don’t have to rev the piss outta your motor to make power with a turbo. If its a race car then its a different story. I would really like when people make posts that they say," its my opinion, or I have heard but not tried it myself". That way people that are trying to learn don’t get led down the wrong path by someone who has no hands on personal experience with the subject at hand.
:werd: sorry, i took that title… hehehe
it runs well though, it’s like a high compression LS. and since the crank is made to rev higher, it’s a little less stress on my mind when im at higher LS rpm’s… hehe
and also, im the first to take the title as the turbo vtec/b20 also… 
my setup is a JDM ITR block w/ b20z head, 92-93 integra cams basically, same specs, and some other little stuff…
i messed up my LS motor, so i needed something to work. 
This thread probably has more mis-information in one location then i’ve ever seen
