I currently have a 2001 gs-r motor with 52,000 miles. Im planning to buy an ls block and add a 84.5 mm bore and AEBS sleeve it, aries high compression pistons, aries forged rods. should I upgrade ignition? how reliable is this? is this a good set up? any advice? thanks for the input!

 

nice setup indeed

 

it's as reliable as you put it together to be.

 

i would never go from a gsr to ls/vtec, why not just put a b16 head on the gsr (more reliable).. i'm basing ls/vtec reliablity on the fact most of them aren't built well enough to be as reliable as a gsr, b16 or hype R motor

tell me, what makes a b16 or type r head on a gsr block more reliable than any vtec head on an ls block?

 

I myself have an lsvtec which has been reliable for over 2 years of getting beat on, so i am alittle biased towards the lsvtec. But....Why not just send your current gsr block off and get the exact same work done to it???? it will be just as good, plus already has things like block girdle and oil squirters...and alot less hassle.

 

hey, if you want a built cr-vtec let me know. i have a b20b, golden eagle sleeves, 86mm bore, 12.1 to 1 je pistons, unorthodox underdrive pulley, dc 4 in 1 not 4-2-1 header, ported and polished b16 head, ctr cams, dc cam gears, and itr intake manifold. i ran a 13.79 with bad traction in my dc4. the only thing the motor needs is new rings. it still ran this time on what i consider "bad rings", and i still drive it everyday. i'm looking to go turbo so i don't need my all motor set up anymore. let me know if your interested. leftcoastdrifter@yahoo

 

the gsr head is fine, but the b16 flows much better when tested

 

i wouldn't go lsv if i had a gsr motor. lots of people turn to lsv because they already have an ls block. it's much more easier to put a 16 head on a 18c instead of an ls block. i have an lsv and it'll take more patience to put it together to make it a good setup. i've had it for about 9 months and i take her up to 8100 3-4 times a day.

 

is the lsvtec motor good for daily driving?

 

i would like to go ls-vtec because it will produce more lowend and over power than a gs-r with the same mods.. the displacment is larger in the ls block and the stroke is also longer than a gs-r.

 

yes, but the ls/vtec motor setup is notoriously unreliable. Depending on the build quality, and attention to detail that is. Many people have built ls/vtec setups that have lasted quite a while, but generally ls/vtecs tend to develop oil leaks. Do a good job, spend your money, and you could build an ls/vtec that will create more power than a GSR yes, but throwing in a GSR motor would be more reliable.
Also, the ls has a longer stroke, yes, meaning more low end power, but it also means more side-loading on the cylinder walls at higher rpms. So without some block work, you risk cracking a sleeve every time you decide to rev past 7200.

i had a gsr at one time. yeh ls-vtec is better if u had the right person to do it or right set up.

 

i say keep the gsr motor if you like to keep being reliable. Any modded motor will crap on you. Just depends on how good it was put together will determine how long it will last.

Nothing beats reliabilty like from factory.

agreed!!

 

a well put together lsv will last just as long as any motor.

RS ratio overrated and will not have a notorious effect on durability.

The pr3 head flows SLIGHTLY more than a p72 head at high rpms nothing to really worry about. Gsr head is a way better head overall.

damn noobs posting miss information and nonsense crap...

As long as a knowledgeable, experienced honda mechanic does the build it will be as reliable as any toehr B-series but it really comes down to how and who builds the motor. I would say probably 90% of LS/vtec problems comes from a bad build and/or lack of knowledge, I have seen plenty of relaible LS/vtecs built and still running great 100k miles later.

 

Hey how did the ls/vtec project go? any advice bceause i am about to try that

this isn't quite accurate. the b16 head does flow better, but it is to a degree that you would never even notice. it's a number on a flowbench. i could switch your b16 head on an lsvtec for the same setup with a gsr head and never in a million years would you notice.

 

If u are going to do all of that i would recommend going turbo. U are going to end up spending 2000+ and may barely break 300 hp. Throw a turbo on lower compression and u will be making far more... Also i would get the valves re-done

 

that is a bad setup....stay with a GSR head motor

do a turbo setup, NA is just not a good route for hp, also u cant escape the high compression wear on the highway unlike the wear of boost

To do Turbo right is going to be 2-3 times more expensive not counting all the tuning needed, Turbo is AWESOME but to compare to all motor and say it's just not worth it????Come on....... If done right the LS/VTEC is very reliable, not too expensive and can easily run 13 sec. passes all day long down the 1320. So what's wrong with that??? A turbo done right even if you do all the work your self is going to be around $4k-$6K give or take. You can't beat Turbo for all out power and speed but If your not going ***** to the wall then why spend SOOO MUCH $$$$?????
