ls/vtec vs. engine life - Honda Forum / Acura Forum

eppo · 07-03-2002, 02:31 PM

i would really like to do the ls/vtec conversion on my ls, but wondering what it will do to my engine life. right now i have 28k on my engine, and want it to last as long as possible. if i do the conversion will i start having problems with the engine? everyone talks about how much hp you get but are there any repercussions?
anyone with ls/vtec please post, how you like it, how long you've had it, and if you have had any problems, from blowing your engine to engine noise.
thanks

This is a quote from an integra forum thread titled: reliability of LS/VTEC

Randyman-
the "unrealiability" of the ls/vtec is way waaaay down in the dark ages. the unrealiable aspects has been fixed. all the previous ls/vtec setup back in the days had some bugs in it -- i.e. improper lines, improper installations, improper machine work that was necessary for the vtec head to be swapped to the ls block. the only unreliable things that i keep hearing about ls/vtecs are the ones that didn't do the job right -- leading to oil leaks here and there. even installing the headgasket wrong.

i've had and ls/vtec for 3 years back then and it was stock. stock gsr head, stock ls bottom (with 137,000 miles), gsr oil pump, ls water pump, ls timing belt. i even squeezed 55 shot of nitrous in it and it still held. no oil leaks, no nothing. just oil changes every 3000 miles.

now i have a fully built b20/vtec for almost a year now and i don't have any problems with it. the setup is just like an ls/vtec, but with more displacement, and bigger bore, and all that good stuff.

hth.

I agree with him. Randyman and Jayman320 here on SHO have had great success with their LS/VTEC and B20/VTEC swaps. Don't plan on reving it to 9k. Make 8k your limit, bulletproof your bottom end when you build it and you shouldn't have a problem.
