I have heard the LS Vtecs break down alot because they aren't very stable engines. I am looking for a new engine for a daily driver and a racer, either GSR or LS Vtec.

What should I get and why?

thanks

 

I prefer the GSR for a few small reasons. The GSR has oil injectors, and block girdle, and a slightly better rod:stroke ratio.

 

how good are you mechanically? If you truly understand engines why not go GSR and modify it? I have heard of guys that install the LS crank and rods into the GSR and have good results. there are a ton of things you can do.

dont need squirters at all when using forged pistons, dont need a girdle, and rod/stroke means basically nothing.

LSVTEC all the time. build it right and itll love you.

if you are mechanically challanged, get the gsr! get a ls/vtec only if you can afford it, the people you hear having problems with their ls/vtec, are the one who don't have the money to build it right! i been driving my crvtec for over a year without a hickup!

 

GSR, u get guarunteed power w/out having to worry about ls breaking

 

if you've got the money, I'd get the gsr just so you'll have peace of mind that it's not gonna leak, break, etc. or whatever the rumors that some of the anti-lsvtec people are saying. My lsvtec in my car have been in there for over three years and driven everyday w/o no major problem. I'd still get a gsr (if I had the money)knowing that I can make the same amount of power that I'm making in my lsvtec because it's a motor that the actual honda engineers designed; so it'll somewhat make me feel a little more confident in it's reliability....that's just me. Whatever u decide, hope it works out for you.

 

gsr is a better block by design.

ls and crv blocks can be built to be nearly as good .

Remember honda does everything for a reason. They would not spend the money adding squirters, girdles and extra webbing for looks.

ps I run a crv block

 

if you upgrade the pistons though the oil squirters arent needed. in fact they are often removed. the b18c stock is a better choice than a stock b18b with stock vtec head though. you really got to look at your budget and figure out where you wanna go from there

 

Could someone tell me more about putting ls crank and rods into gsr, What would be benifits or downfalls?

 

How much are GSRs and LS-Vtecs?

more stroke
more displacement
more compression
more torque
more horsepower
more midrange

less top end

 

At what top rpm range would probably suffer, anything above like 6500 or what? What this be a good mod for a gsr?

 

Your talking a difference of around 500 rpms in the rev range not to much. With good airflow a ls stroked engine can peak over 9k easy

 

ls/vtec is not OEM honda.

GSR is OEM honda.

go with a gsr block and enjoy the reliability and power. yes, ls/vtec's can be built reliably although i don't know of many around here that have lasted more than 30k miles and kept good compression...and there are many guys around who can build reliable motors.

 

bump

 

mikesarr and trever,

so you can put a ls crank/rods into a gs-r? wouldn't it go the 1.8mm right into the head? considering the stroke of a ls/crv is 89mm and a gs-r is 87.2mm.

 

im not sure on how it all goes together, I know it can be done. the extra power from displacement on that motor can be had another way. too cumbersome IMHO.

GSR all the way here

 

ls/vtec is simple. not that big of a deal. the only major work you have to do is to block off the oil path in the vtec head, by tapping it and installing a plug. then theres a copper blockoff screw in the back of the head that has to be heated up to be removed. and thats where you end up re-routing the external oil line for vtec. other than that, the head bolts right on. theres nothing that can go wrong when its done right. and you cant really do it wrong unless your lazy and you half *** it!
