you know i really love honda's but im really getting sick of every one saying not to build a ls non vtec motor realistically you can make any power you want with either motor just the fact that a vtec is more "streetable" is not a reason for saying not to build a ls the main reason i say this si for the fact that the majority of high horspower vtecs are not even driven twice a week (some are i know) but the point im trying to make is that you can make great power on both just all depends on the build and with FI comes into play they are even closer then people on here like to admit and just so you know i have personally seen a non vtec motor older mazda make over 600 horses so vtec is not every thing! people need to give it up granted its more "streetable" but big horsepower is not street able out of a fwd any ways here is a link of that car (update sense then) car now makes 600+ i have seen this car when i was in florida and asked a hell of alot of questions (91-94 escort gt came with mazda "miata" bp motor)

People use/go the VTEC route because more power can be made with the same amount of money spent on an LS/non-VTEC motor. For example, a GSR motor makes more power with a bolt-on kit (like a GReddy kit or something) than an LS using the same kit and PSI of boost.

I do agree to a point about VTEC motors being more streetable. Take this, if you put a big cam in a VTEC motor, you will not be using/riding on the bigger VTEC cam lobes, thus making it more "streetable". On a LS non-VTEC motor, once you put in a big cam, your motor will ALWAYS run on the bigger cam lobes because there are nothing else to ride on. This will cause "rumbly" idle, car dying out coming to a stop, etc...

For a budget turbo setup, most people go with the LS motor because it's cheap to make power and be reliable (depending on the tune of course).

that video shows a ford .....

on the same note, you can put a killer cam kit in a vtec head effectively killing hte vtec and it will still run circles around the ls head.

the vtec head flows much better and can make more power at lower boost levels, basically the vtec engine w/ or w/o the vtec system will not work as hard.

sure you can cram enough air into any engine and make power.

lets try to keep this a discussion, i dont want to lock it.
you have to remember too the vtec was the first try at making an engine that had good low end and great top end. now look at everyone else doing that.

i am not hating on the ls, 1quikfodo has one of the setups i like alot and performs well.

ya ford escort gt's from 91-94 had mazda motors... also the motor out the the GTX? stock turbo car from mazda just minus the turbo .... even if the valve cover on the ford says ford doesnt make it a ford... just like some plymouth lasers have a 4g63 witch is a mitsu....the ford has bp stamped on the block i use to have one for a better quik lil car too.. for being stock and rusted body...

but ya i was just sick of seeing people beating on ls builds most the people that hate on them really dont know much at all about motors obviously just by the fact that it was vtec means its better? that mind thinking is getting old... heard it to many times.. and ya the lopping thats encountered i understand completely its like the radical cam we have the drag 355 chev makes power from 4.5k to 8.5k stout motor thats for sure

but im one my self i have a stock ls in a crx being finished along with car but torque is the real goal and anything round 230hp will make a lightened crx fly... torque is what gets a car of the line and out of a turn.. look at the old 80's z28 tpi no big horsepower but LOTS of torque and it was a quick car

in some cases its about streetability but most 800+whp cars arent running them on the street, they are purpose built track cars and still using vtec heads for a reason. they make more power with the same amount of air. they are just more efficient and take less work to push air through.

noones arguing you cant make power with an LS. its just easier, cheaper, more reliable because you arent going to push it as hard, its more streetable, it just make sense to start with a better platform. when you make an argument for running an LS motor the only reason to run one is to be different there is no advantage of running one over a comparable VTEC motor, i know many will say they make more torque, but that is just an illusion because they run out of power in the upper rpms so they are pushed harder and run more boost which results in huge torque gains in the midrange to acheive the same power. a vtec motor can make the same torque but just make more power with the same stress.

people do hate on ls motors, mostley the heads, but like stated the simple fact is you can make more power with a vtec head, how many ls heads do you see making 600whp...They just cant flow as much as a vtec head can..

With the coast to build an ls head is the same as vtec and you make more power, im not hating, just the simple fact the vtec head works better than an ls..

kyle3108

o i completely agree a vtec head flows better but thats not the point the point is that to many people hate on them... my way of thinking is if you hate on it and get beat by it u should shut up because it all comes down you engine building and picking specific areas to spend you money on... look out for my ls build coming soon should have pics every step of the way.... head shave, block shave, head pnp... know some people that know some people.. if you know what i mean... all will be done for roughly a hundred dollars.. use to get our drag cars redone for bout 250 with complete rebuild on top of it.... just friends willing to help out...
