ok so i traded my turbo kit for a full ls/v set up..

b18a1 block
gsr crank with rods
b16 pistons
89 b16 vtec head mild port and polish.

got all new gaskets and washers for the motor... but ive heard ls/v give a lot of oil leak problems wat can i do to avoid this??

 

i hate to break it to you but you pretty much have the making for a really shitty gsr motor.

putting a gsr crank in an ls block is the exact opposite of the whole concept behind lsvtec.

you see the ls block has a larger stroke which is where you get the extra power over the gsr stroke. so when you put the gsr crank in a ls block, it has the same stroke as a gsr, just in a shittier block....

hope this make sense.

as far as the lsvtec "having a lot of problems" wheater it be oil or anything else, it all has to do with how the motor was built. build it well and it will preform well.

makes sence got ya

 

You essentially have whats known around here as a "poor mans type-r". Do a search for that and youll come up with a ton of stuff.

 

he is right, lsvtec done rite will not leak oil, i dont know where people get leaking oil from? unless they didnt do it rite, i built a few ls/vtec they all ran fine with me, just make sure u get the vtec oil passage on the head welded or plug and the rite fittin for the oil feed line then u should be fine,

 

isnt poor man type r is with a gsr block and b16 head not ls block? i would just call this a shitty ls-vtec

 

Even if iot's shitty or not... it'll still make decent vtec power

 

its basically a poor mans' cuz of the 87.2mm stroke.

 

as far as the tapping goes it already pre tapped...and wat would i want to DO and NOT DO to aviod leaks. im new at this whole lsv thing, im more a of boost guy..but im tryin something new. so help me out pplz

An LS/Vtec shouldnt have anymore leaks than a normal Vtec motor.

Only thing to really leak is the Vtec plug or oil line. Just make sure it is all tight.

 

i would get arp rod bolts and a vtec oil pump and water pump and u will have to get a gs-r timing belt, sumone people might think u dont need to swap out oil and water pump but i do it just to be on the safe side. rod bolts is a must i say if u want to rev high

 

the oil line may be to small i would check that cause i know u have to use a bigger oil line when ya do the LS/VTEC swap.

 

good info guys keep it coming ...and i already ordered a set of arp head and main studs

 

-3 oil line should be fine

 

definitely go for it. the only difference would be that you have the shorter stroke and .2 points less for compression. i am running this setup cause i had an ls block and picked up some gsr internals for really cheap. i threw some arp rod bolts on the gsr rods and some p30 pistons so it gave a comp around 11.5 with the omnipower flat faced valves. my setup put down 174whp and 130 ft lbs of torque just with 30 mins of tuning and i still didn't touch the cam gears. i only played with the vafc and the a/f is still pretty sloppy. ran 14.1 at the track with a 2.3 60 ft. i can definitely can get into the 13's with this setup in a heavy *** ex coupe
