just wondering how many here have done it, and if it was noticable gains…
how do you all like it?
i’m not asking for myself…
i have a friend who might wanna buy my 92-93 cams from me but he wants to know how much difference there is.
i would buy some jg 301 cams used , sold mine for 150 dollars i did get my old ls dyno
my mods old mods
jg 301 cams
jg tbody
aem cam gears
rs akimoto intake
greddy exhaust
before tuning the car dyno at 127 hp to the wheels and 118 lbs of torque after tuning the gears set in intake + 4 exhaust -7the car dynoed at 136 hp to the wheels and 124 lbs of torque ,the torque was very nice the cams pull good from 4-6500 rpm ,stock g2 dyno around 105-110 stock , so the jg 301 and other few mods gave power the stock 92-93 cams give more like 2-3 extra hp to the wheels ,my suggestions is get some crower cams or jg
i have the jg cams, not bad for 170$. but if was to do it over again…and stay all motor, i would do it right and go with crower and do the springs and retainers.
i also had a dc header, not “headers” and i honestly am faster with the stock manifold…i sold the header:p
check this out…(i did all my own work including p/p)
i have a ported/polished head with dual crower valve springs and titanium retainers. 3 angle valve job with new exhaust valve guides. i have stock 92-93 cams with AEM gears(+2,-2). the head is shaved .030". the bottom end is all stock with 156,000 miles on it… compresssion is 175,170,170,175. (and i burn a little oil, not enough to notice on the dipstick)
i have an aftermarket ECU chip. (redline 8200, but i never go past 7000 cuz the cams dont make power past there)
i have a generic Intake, Greddy 4-2-1 header off 98 gsr, a custom test pipe with o2 bung welded in. and a Greddy SP exhaust…
next weekend i’ll know for sure, but i’m running very low 15’s.
i do have some weight reduction and i have the RS…
my goal is to get my teg with stock cams in the high 14’s…
there’s alot more i can do while still using the stock cams.
i almost feel like trading in my extra set of 90-91 cams and see if i can tell the difference.
i cant run my “crazy” cams until i get the Apexi S-AFC i’m saving for. and i also have a set of b16a (pr3) pistons to install to help with the crazy cams i got. i also have an extra IM/TB that i’m going to bore out to 62mm… that should help also. either that or a Skunk2 IM.
properly tuned with the safc, fpr, and cam gears, i’m hoping to run high 13’s low 14’s… i think its possible.
anyway, back to my point… the Stock 92-93 cams cant be that bad if i can get my car into the high 14’s with them…
sorry to put a dampier man but with that setup 13s doesnt look possible maybe mid 14s with weight reduction to high 14s depends if you are running slicks or drag raidials, look at all the mods g2guru dan put on his car to run 13s , if building a all motor ls motor was that easy i would of stayed with my old ls instead of going vtec ,if you want 13s for your setup try a dry 60 shot of nos or a 6psi turbo kit good luck please post your times up im kinda curios
i should ask dan to weigh his teg… also i’m sure he’ll run alot faster than 13.8 if he tunes it.
another thing.
really if you think about it, what difference is there in the cams of the LS and the VTEC cams…
the way i look at it is this: vtec cams have a nice easy lobe for streetability at idle…
its all about getting air thru your motor.
there’s alot of other cars that are fast that arent honda that dont have vtec… how do they do it? simple, lots of work… port/polish, and BIG lobed cams.
look at those ford focus’s (i hate them but i’ve seen some fast ones)…
also i’ve seen some fast mazdas and toyotas…
i dont buy that “vtec is the best” … i agree vtec is nice… its because it makes a person be able to run an extreme lobed cam on the street cuz of the low and mid range lobes.
i believe if a person builds his motor properly he can make it perform as good as a vtec… it might not be as “streetable” as a vtec car. but it’ll still be fast.
93integrars im not saying the ls motor is a bad motor , just its hard to build a 13s all motor b18a in a g2 integra , b18a motor can reach 13s all motor alot easier with a light car like a crx or civic hb
as for cams non vtec aftermarket cams have good midrange power but no top end , vtec aftermarket cams keep makeing power to redline ,i never ran my old ls setup in the track , i could beat gsr with bolt ons so i figure my g2 was running low 15s maybe high 14.9 or so ,im not saying 13s all b18a is not possible but its going to require lots of weight reduction ,mods in tuning good luck keep us updated
i understand what you’re saying 92lsR, what i’m wonderg is why a vtec motor has more power up top end?
this is what i think…
vtec head has 33mm intake valves… ls head has 31 mm intake valves… same exhaust valve size (28mm)
vtec IM is built for better performance at higher rpm. and bigger TB (ls 58mm, gsr 60mm, ITR 62mm) the LS IM is made to make more torque and not built for high rpm of vtec IM’s
vtec cam his higher lift and more duration on their “high” lobe which means more power at higher rpm.
GSR/ITR have a block girdle to strengthen the bottom end for high rpm operation.
VTEC ecu’s have been tuned/optimized for high rpm operation.
LS ecu’s have been tuned for economy…
…
this is what i’ll admit… its alot easier to go fast with a vtec motor and be streetable.
everything i’ve mentioned above can be changed on the LS to the vtec equivilant.
dont get me wrong, i like vtec, i’ve just chosen to go a different route.
it will just take a bit more work to do it. its not impossible, just more work. and money. (depends on how you spend your money)
right now i have $1000 in my car for power goodies (I/H/E/chip/P-P/valve train/camgears/valve job). granted i’ve done alot of my own work, and shopped around and got as many good deals as i could. but i feel for a low 15, high 14 sec 2nd gen teg thats pretty damn good.
i’ll have more as soon as i add in my race cams and other goodies.
but thats expected. the Apexi S-AFC will cost me about 300$… and some of the other stuff i have to get will cost too. such is the life of a Speed addict
The vtec head has a better combustion chamber shape and higher compression. as for the vtec, it is meant for fuel economy not power(i.e. small cam lobes most of the time). If you want make power in the vtec head you have to remove the vtec.
I would be very afraid of Ford Zetec, that head stock flows way better than a ported vtec with better valve placement.
13’s shouldn’t be a big deal. The suspension is where alot of time can be made.
something of interest… let me know what you guys think.
well i learned something interesting today about regrinds… i measured my intake cam lobe… and got .236 lift and the multiplier of 1.75 gives me .413" gross lift. well theres one problem i’ve found with that. when i measure actual lift of the valve, i get more… to the value of .452" total lift. what i discovered is that the multiplier or rocker ratio changes because of where the lobe crosses the rocker pad is closer to the pivot bolt. i figure the actual ratio is 1.915. i think this is something that happens with the regrinds and and with the rocker geometry.

wtf does all that mean haha
anyways, i just finished my car today! 95 b18b head on 90gs b18a block. sorry i havent gunned it yet, but im about to in a few minutes. oh i also apologize deeply, cuz i have an automatic ok the differnces so far driving around the city (like upto 5k)…
bad- under 2k i feel a huge lag. like if you have a cai and blip the throttle cable under the hood, you can see the pipe and filter surge a moment after. this could be caused by something else i dunno. i just know it wasnt as noticeable on the 90.
good- at 2k i feel a big pull all the way up to 5k. with the 90 head, i didnt feel the pull until 3500.
i only have intake and exhaust right now. also factor in the head is 5 years newer, and i cleaned out throttlebody/intake/exhaust manifolds and ports on the head. they were very grimy.
ok boys im back. wee hee what fun. i dont think ive ever got to 90 so fast.
bad- i cant seem to peel out anymore. i used to be able to do it almost everytime. i guess thats related to the initial bog at partial throttle. oh well i hope its something else…
good- 2k all the way up to 6800 pull. fun fun. i even had to teach two accords, two civics, and a neon a lesson on the way back hehe
so should he do it? sure. its apparent i cant pinpoint the differences exactly, but the numbers do it themselves. 10 more hp. give or take one or two due to the ports/intake/exhaust manifolds.
oh i forgot to mention, during the swap i also did the throttlebody coolant bypass. im sure that added a whole .5 or 1hp
