True Noob Question-LS/VTEC? - 5/5/2008 1:09:17 PM    BuckHijo   Posts: 18 Joined: 4/28/2008 From: Tallahassee, Florida Status: offline Sorry but I have a noob question, what is an LS/VTEC? I am looking at a '95 Civic EG6 with an LS/VTEC in it. Thanks for the help guys and God bless. < Message edited by BuckHijo -- 5/5/2008 2:22:33 PM > Post #: 1

(and thank you for being able to spell vtec correctly ) *edit: crap, bcivic beat me to it < Message edited by reaper2022 -- 5/5/2008 5:53:15 PM > _____________________________ My car - for sale!

What upgrades should be done to the bottom end to make it more reliable? Also should there be anything done to the ECU to make the VTEC run? or run better? (in reply to reaper2022) Post #: 4

Looking at the mods, he already touched on the bottom end a little.  I'm not sure how the stock crankshaft will hold up though.   By "less reliable", I didn't mean an ls/vtec will fall apart if you rev it high, I'm just saying it's obviously not going to last as long as a b18c revved to the same rpm (since the b18c was basically designed to have the s**t kicked out of it by 16-24 yo males lol). Overall, I'd say it will be a reliable engine, just don't rev the p**s out of it in every gear every chance you get. And that b16/ls transmission is a good combo... you get the quick acceleration from the b16 transmission, but then throw it in 5th and the rpms will be nice and low for cruising *edit: forgot the "t" in bet, and I figured it'd confuse you if I didn't fix it lol < Message edited by reaper2022 -- 5/6/2008 3:30:23 PM > _____________________________ My car - for sale!

I haven't done any research on that swap so I was just wondering what I should be looking for and what might need to be done so thanks for all the help. Now price wise is the ls/vtec swap more than say a stright b16 swap? (in reply to reaper2022) Post #: 7

I don't know from experience, but I'm going to say probably... especially since you have to piece it together. _____________________________ My car - for sale! (in reply to BuckHijo) Post #: 8
