got this stock b18b1 in my del sol ... 43,xxx miles on it.. deciding if i should pull the motor out this winter and start fully building it(will take a few months) or should i buy a b16 head, send it to a machine shop, slap it on, boost, and keep internals stock for now n slowly build it?(could be a fast process).... let me know what your opinions are and why ...

 

what is your defination of build?

 

Fully building the ls for boost, or all motor?

I would do ls-t

 

Why do LS/VTEC + boost? It should be either or, at least in my opinion. LS/VTEC setups are already not very reliable themselves, adding forced induction would only make it less reliable methinks.

If anything, I would just slightly build your LS (if at all) with ARP headstuds and headgasket just to prevent headlift. Get a good turbo kit from GO-AUTOWORKS or something, and you'll be making a good amount of power for a cheap price.

 

trying to make atleast 450whp when done on race/highboost...

 

^^^ i like the idea and since that requires opening the engine i would do a block guard while your at it. THEN boost. Although you can safely boost a stock LS

 

hmm i guess we will have to see ... since this post got me no where haha

 

this is the common misconception. LSvtec builds are now very popular and very reliable when they are done correctly. i have been running mine for over a year now as well as many of my friends over 2 years, all boosted. LS-T is fun, but all it takes is a vtec head and you open up a whole new wprld of power and potential. just keep in mind i made 340whp on .54 trim turbo @14 psi and my buddies LS-T on 17psi with a .57 trim turbo barely hit 300whp. As long as the lsv is built correctly you will safely and reliably make more power day in and day out.

 

OP i did an all OEM build on my car as well, no forged internals, just head studs and rod bolts w/ a gsr oil pump and water pump

 

go with the b16....do your self a favor and save ur self a headache

 

Why would he spend the money on another engine when he already had one?? and downgrading?? I got a b16 there junk there rev happy motors.. Save the money get a vtec head (make sure you tap it for vtec) and slap it on. You dont have to spend tons of money for a lsv conversion. You can buy a t-fitting and line at a local hardware store and tap it into your oil pressure switch on your block will do the samething just not as fancy...

 

pull the motor and rebuild the bottom end

 

Personally I would do the LSvtec now and start saving up until u have ALL the cash and then tear it down and build it. I got a good buddy that has been running a LSV for over a year and hes got over 30k miles on it, and his old lady has a heavy foot. If you do them right they are reliable. I also had another buddy that did it on his teg and it lasted about a month, it all depends how you do it
