Is Vtec worth it..?

Going from an ls motor to a gsr, I only picked up 0.10 seconds in the 1/4 mile, same trans, same trim level, same chassis weight, same driver weight, both w/ full tank. Boost it if you want more power. That's what I should've done in the first place, would've been much more satisfying in the end. This will be my next build, lots of boost.

Just curious, why wouldn't you put the GSR trans in with it?

lsvtec done correctly takes about the same amount of money as finding a gsr/b16 longblock. I say dont go lsvtec unless u dont really care about reliablility my lsv lasted a day cuz all i did was throw head on and a type r ecu.dont let anyone lie to u though lsv is alot more torquey then a gsr.
torque wins races hp sells cars

Cuz I use it for dd and long distances. It actually has proved to be a significant asset for competition.

I believe the gearing in the GSR trans helps offset the lower bottom end torque but I can understand why you'd leave the LS trans in.. I plan to throw an LS 5th gear in mine if I ever need to take it out.

Thanks, thats alot of suggestions. I thought about going Ls/Vtec or in my case Gs/Vtec, same thing, but thats a crap-ton of work. The head, arp head studs, rods, block girdle and drilling what have you. If I swap in a b18c i still have to do a, auto-manual tranny conversion, so say 2grand for the motor and around another 2grand for the transm conversion, not including miscellaneous needed parts and labor. I was thinking of just selling my gs for about 4 g's and buy a gs-r for 5 or 6 but still would have to invest in fixing it up, but no motor or tranny work.

turbo, right now would be too much for me, daily driving a turbo and spend more gas not to mention look for custom turbo manifolds that'll fit.

how much is a swap in and/or tranny conversion in your area? around here tran conversions like 2grand..

if i dont find a good deal on a gs-r i might just end up deciding that be better to stay with my gs and continue building it, everything's sound, legal, and smooth mechanically, just needs a new paint job and minor body work. i have new hids/halo housings, struts and cai. if i get a good deal on a tranny conversion and the motor swap, fuk it ill just stay with it. ive gotten attached to my car, love driving it, and its only got 120kmi with life left in it and been treating me right.. plus definitely helps with the ladies.. heehee :)

Its still ls/vtec. Gs is the trim level of your car, which would be certain options. Any b18a/b is considered an LS whether its in a ls/gs/rs.

adding vtec will not make you much faster, i love that common misconception when racing people. "but bro, you dont have vtec in that thing, so it doesnt make that much power overall"

Doesnt the Gs-R motor have about 180hp? compared to the LS/GS 140/150 hp ? thats closer to 200 stock. not to mention 8k redline as opposed to 7k rpm, and variable valve timing, i dont have any o that. just 150 stock, no variable valve timing. just dc headers and aem intake.

Shut up baby, I know it!

the USDM B18C1 has 170hp rating from the factory @ 7600rpm, and 128 ft lbs of torque, the B18B1 is 142hp @ 6300rpm

The common mistake people make is looking at RAW numbers, not how the engine makes its power, if your doing autox, roading racing, etc and you want a versatile high revving motor that has alot of giddy up in the upper power band then a vtec motor is for you, but for what we call usable power on the street, the GSR suffers immensely. My friend was gung ho about his RSX Type-S when he bought it and now he realizes the disadvantages of a car that makes 26hp @ 3000rpm. Your real world gains in the 1/4 by switching to a GSR are taken away by the fact that it takes so long to get your usable power in such a short range of the power band itself. I would rather have a better rod x stroke ratio and a lower revving motor with a much more usable area of power that pulls across the whole range vs a high revving gokart motor.

Obviously you can get around alot of this if you put work into the motor, tearing apart the internals and replacing it with parts that make up for these disadvantages stock, even on both motors. However the whole idea behind a swap being so worthwhile really isnt all that its cracked up to be for the price.

Im not expert but, im pretty sure they calle it Ls/vtec to all because they all have the same motor. LS and GS have the same motor. You can call it rs/vtec if you want, its still the same. Ls/vtec is just more common term
