i am wondering if i can do an ls vtech conversion with this stock b18a1 and is it wise to do this converson if this car has over 250k miles and besides he kit what else do i get to complete?

 

yea i believe you can but i heard there not that reliable. what kind of head are you trying to use

 

they are reliable as long as you buy the oil kit from golden eagle which will allow more oil to the head...ls blocks only have one oil valley where vtec motors have multiple that supply the head..there for golden eagle made a kit that allows more oil flow to the head...also they say they are unreliable as a turbo set up due to an ls vtec cant rev as far as a gsr or a type r vtec engine..and people assume since its the poor mans type r or gsr motor that it can be reved just as high and it cant be...other then that on my old lsVTEC turbo setup i went 10.08 and it lasted for 3 yrs...so reliable yes as long as you do it the right way and no short cuts

 

yes, you can do this conversion on a b18a1. would it be wise on a 250k motor? it all depends on how healthy the motors is and how much you want to spend. it can be extremely reliable if built right and not just slapped together in a garage. you will need the VTEC head, a conversion kit, ARP rod bolts, and a few other things. try searching, there countless threads about lsvtec, do some reading and you'll find exactly what you need to know.

 

if you want to do it the right way, you'll get a lower mileage block, because i dont care how you do it, if you're revving a block with 250k miles and stock internals to 8k you're going to blow it.

pretty much everyone has summed it up for you perfectly...as long as you do it right and don't cut corners, than it'll be just fine. i'd still be kinda easy on it with the engine having 250k on it, but if the engine feels strong...then what the hell. good luck with the build

 

While you have the motor out take your time and do a total rebuild from the bottom end up. That's what I'm in the process of doing with mine. Balancing the rotating assembly, resurfacing and honing the block, replacing the ls pistons and rings with itr and new rings for higher compression, replacing all of the bearings, pumps, and gaskets, etc. While its apart might as well do it right so it will last like a new motor unless you've got money and time to waste. Also take your time and do what you can yourself, I've done everything besides machine work myself. Just make sure you take your time and don't cut ANY corners at all.

 

thanks for the info guys really awesome just waiting for my hatch sell for the head and the conversion kit. pics coming soon


in the mean time the exhaust side of a b18a1 is it the same compared to a
b18c1, b16a3 or b18c5 like i want to buy a header and i was wondering if it will fit on a vtech motor?

 

Intakes are different between VTEC and non-VTEC engines but the headers all bolt up the same. You can buy a header for your LS and use it on your future LSV. Which, by the way, I would recommend rebuilding, balancing and adding ARP bolts to. Stock LS internals were not meant to rev past 7k and 250k miles doesn't make things any better.
