i dont know whether to do all motor ls or lsvtec???which would be the best way to go?and also i dont have a spending limit but would somewhat would wanna save money. ..::: THANX:::....

 

To get more power, the lsvtec would be the better way to go! I am running an lsvtec and LOVE the power it gives. It will definitely cost you though to get everthing done the correct way. You also have to make sure that there is a reputable shop that knows what they are doing to install it! It isnt your normal engine swap! If your car is stock, I would try getting your basic boltons and see if you are satisfied with the power and if not then go lsvtec.

 

We just had this post war of B20 vs B20VTEC. Same thing. VTEC head out flows the LS head. There's your answer. Non Vtec is "cool". You want to be fast or have "bragging rights"

Why isn't this a normal engine install? He already has the B18 in his car. It's a direct bolt in. You can remove an engine in about an hour or two with the right equipment. The only major thing is dismantling his engine to get the machine work done.

 

If you want it done right... you are going to have to do the oil line to the block and head. You are also going to need to modify the head for the dowel pins to match the LS headgasket. If that is not done right, then there would be leaks and what not, which is not good! These are not done during normal Vtec block swaps! So it requires more work. I wouldnt recommend getting it installed by someone who hasnt done the above before because those are critical things that need to be done for it to be that much more reliable!

 

I use to have an Ls and now i have a LsVtec. Both motors are motor and i like the Vtec much better,although nonvtec wasn't so bad. So i would say go with the Lsvtec

 

"you are going to have to do the oil line to the block and head. "

They sell those as a complete kit. People on this site and others prefab them.


"You are also going to need to modify the head for the dowel pins to match the LS headgasket. "

Full race sells a stepped dowel pin kit. not sure about any others. This eliminates the need to drill the head.

The most important thing in my mind is the machine work. Getting the ls rods machined to allow higher compression pistons, the balancing of the rotating assembly, a bore and hone, ect. Instalation is still very straight forward. Assembling the motor is a little more difficult but not impossible with a little mechanical knowledge and some friends who have done this sort of thing before.

As far as reliability, ARP rod bolts is a big step. Also going with a vtec oil and water pump.

I heard that LS vtec leaks oil from everyone that I talked to. Did you have the same problem with your setup? I believe it was leaking from the head area. Haven't heard of a successful setup yet. I'd like to hear more on your setup if you didn't have any leak problems.

 

my opinion on this is....stay ls and go turbo......alot of peeps that i have seen that went ls vtec.....lost oil pressure....then kaboom...dont get me wrong if you build it correctly.....you get great power...but you will have to have back up money all the time....thats it....

 

Take it to a reputable builder. It will be just as reliable as any other Honda motor. It's just a shame there are a lot of examples of ghetto built ones that scare people off from it.
