i blew my crank shaft in my b18c1 and instead of getting her fixed should i just do lsvtec?

 

What???

What is "blow a crank shaft"??? It broke?? You spun a bearing?? If you have done major bottom end damage then you might want to just look at a new engine. If you are going to build the bottom end and you have a good budget then why not go for the LS/V

 

yes i blew my motor. to clarify my question, i want to know instead of fixing my motor, should i just keep the gsr head and buy a cheap ls motor?

 

if you can just build up the gsr bottom end and put a ls crank in it.

 

gsr. lsvtec is gay

 

dude if your crank is fcked up just go on ebay or find a used one here on h-t. you have a gsr why the hell downgrade? i know ls vtec is coo for powa but the gsr is more reliable. and i am sure there are the guys on here that will say ls vtec is just as reliable but they know a **** load more about it then you or i do by the sounds of it bro. stick wit what cha got

 

id put a gsr or a ls crank in it.. reliable is the same with either crank..you will ONLY have probs if the oil clearences arent right and the engine isnt tuned properly...ls for torque and gsr for more topend power...

sigh funny how an ls/vtec would walk over the gsr...and has more potential at that...i dont see anything gay about torque and top end power...but then again..were not all the same...some of us like being 15 second cars = /

 

this question has been beat to death.... and ive never heard of anyone blowing a crankshaft.

 

do it. try something new for you.

the only thing giving you the advantage is the crank doood! the sleeves are better too, but there are many places who sleeve gsr blocks. but i do know what youre saying, there are alot of bad *** ls/vtec setups out there. gsr is just more reliable.

 

how would a GSR be more reliable? as long as the person building the LS/vtec knows what he is doing i see the life expectancy the same...i've own 2, one with 200,00 miles on the bottom end ran fine

 

I think going ls/vtec is a great idea. Since you already have b18c1 long block, you have some of the more special parts that would otherwise be hard to get, such as the oil pan/pickup, main block girdle, and if you want to be meticulous; the oil squirters.

Most ls/vtec guys dont go the extra mile to build it up right, then they bitch when something goes wrong.

Since you have the above mentioned parts, all you really need is some ARP rod bolts, .25 over ITR/CTR pistons (if you blew your motor, you'll need new pistons anyways), balance the rotating assembly and you'll have a nice engine setup that should walk on ITR's no problem.

 

i agree, if done correctly it will be just as reliable as any other built motor. but exactly like you said, most people do cut corners then **** and moan about how it sucks. it is up to you dude, good luck either way.

I'm pretty sure you cannot use oil jets with an 89mm "LS" crankshaft. This is the reason why it's important to used forged pistons in an LS/VTEC; the increased piston speeds due to more stroke and the lack of oil jets makes for more friction and heat.

Not really very true. To make an LS/VTEC more reliable, AT THE VERY LEAST the rod bearings, rod bolts, oil pump, and water pump must be upgraded. If you had the ability to do this to a B18C, it is near indestructable. Also, due to higher stroke, the LS/VTEC has higher piston speeds, thus the engine moves more per RPM and has more engine vibration at high revs from increased rotating mass (the crankshaft is bigger and the rods are shorter). This DOES decrease the life of the LS/VTEC as compared to a B18C.

Just be quiet. Keep on drag racing. Just because it has more stroke does not mean it has more potential. Most of the high power producing camshafts like te JUN III and TODA B make power all the way to 9,500 RPM. YOU try revving a B-Series engine with 89mm stroke to 9,500 RPM to make max power. LS/VTEC only has more potential to make low end torque becuase of its stroke...THATS ALL.

If you want an LS/VTEC with the reliability of a shorter stroke engine you will have to spend $$$$$$$$$$$$$$$. Stroker engines are for people with race cars, not street stunnas like yourself.

 

well you can't tell me something that i don't know from experience...my motors ran fine the one with over 200,000 miles was a stock LS bottom w/ stock b16 head....never had a problem with it. i see what your saying but i've yet to have any problems with them. i'm in the process of building another one now ls bottom /gsr head i like them this one's getting boosted

 

i say go lsv... you wont regret it...


well, unless you decide on a cheap build...

 

I wouldnt consider an ls/vtec unless you are going to build the bottom end . I had an ls/vtec and it ran good but i didnt build up the block and it eventually gave out. Have u thought of building a gsr instead?

 

exactly why you should get a gsr, most people arent gonna build the bottom end. If ya do then LSvtec is more potent because of the displacement, and if ya build it correctly.

 

Ls/vtec will walk over your litttle *** gsr fuuu... Get your facts straight b 4 u talk because u DONT know shittt! u are just a full of **** wit your gsr

 

ok now what i want to know is more about what needs to be done when building a reliable LS/VTEC Block??

whats all this talk about oil squirters and oil problems?

im planning on doing an LS/VTEC because of the power gains. I have a B17 and with a completely built motor, i would be maybe looking at 175-190 whp. Now with an LS/VTEC, i am just planning on building the block and leaving the head stock for now(money issue) and should be hitting around 185whp tuned.

what all is needed when building a relaible LS Block for the LS/VTEC conversion?

this is my plan:

B18a Block (hot tanked, honed, bored)
ARP Rod Bolts
ARP Head Bolts
JDM P30 OS Pistons, Rings, Wrist Pins
GSR Oil Pump, Water Pump, Tensioner, Timing Belt
OEM Honda Rod and Crank Bearings
Golden Eagle VTEC Oil Supply
Golden Eagle Dowel Pins
Golden Eagle Headgasket ---&gt; do they sell them bored out to 81.25 or 81.50????
and have my oil hole plugged on my head
Hondata s100

*** would upgrading the pistons to forged ones that offer better oil supply be better for me? that would hurt my budget *** I read a lot about guys just putting pr3 or p30 pistons in and their engines are fine.

also replacing all the seals and o-rings and any gaskets that may need to be replaced in a normal rebuild.

is this block going to be reliable?? or what? or should i just such it up and build the b17? My HP goal is around 200 whp.

 

lsv is fricking insane when done right.my cousin's build has lasted for more than 30,000 miles.

 

ls/vtec is great

 

will they last 100,000 or 200,000 miles being ripped everyday?

the more i read, the more i dont know..

so many damn options. i can see why people turn to TURBO!!!

 

What all goes with building the bottom end?
