ok as we all know about the swap.........just wanted to know if it would be alright to do it with the stock internals (130,000) miles? i am just getting the bottom-end could i put my internals in it? oh yeah i have a 1st gen b16a.....thanks

 

[PSIKOTICsi]

depends on the condition of the ls motor but i would do a partial rebuild on it b4 you use it.

 

[zcivic91]

oooooh!! so u gotta b16 and ur lookin to do a lsvtec swap.? which head are u using? the b16a head?

basically, this is what i would do...take those pr3 pistons in the b16a block and put them in the ls block using the LS rods...this will boost compression to about the same as the b16a motor but ull have the ls parts for torque!! it would be wise to get new rings and bearings. anddd maybe some stonger rods dependin on how far ur gonna go in the future. so if ur gonna keep adding power in the future it would be wise to get better rods. but the ls rods can handle 8 psi on boost wit good fuel delivery.

butttt...if u plan on forced induction then u dont want the pr3 pistons in the ls block because compression will be too high. Also alottt of people say that a forced induced lsvtec is a bomb waitng to explode..because the head and block werent made to be mated in the first place!! So if u plan on f/i stick with the b16a block.


either way... to be safe get new rings and bearings.

Frankenstein motors should NOT be built unless done RIGHT, which costs a shitload of money. If you just slap some stock Honda parts into the bottom end, especially high mileage, you're gonna regret it...... either do it right, or don't do it at all......

[PSIKOTICsi]

AGREED!

 

[DAFeLUNG]

make sure a LSVTEC or CRVTEC is done by someone who does it professionaly and is fairly reputable. Import Builders and JG Engine Dynamics are two good examples

 

[CRXtc]

if you do the swap DO NOT use the LS RODs because they dont have the right rod ratio........if you have the engine apart yu might as well Bore, deck, and hone the block, then get the right piston to the application you plan on (turbo or NA)....and as for the Vtec head and the LS block not ment to be combined....WTF is a CIVIC TYPE R......daymn people!

 

[Ultraspeeder]

hahah...chill out poeples.....no one said i am gonna do it, and do it wrong! besides if i wanted to i know how to do it, and yes built right it is very safe, and efficient......NO ls/vtec is not a sitting bomb! my boy has an ls/vtec turbo, and its madd fast...so dont talk uless you know.....bore, and hone are basically the same, ones done my hand the other isnt....stating the facts....

Dont talk unless you know? Ok I have seen 2 LS/VTEC motors get blown to shit, one all motor, one turbo, and one CRVTEC grenaded. Bore isnt the same...... for CRVTEC is 84.5mm, and thats the least of your worries. If not built right, both these engines are asking for trouble.....

CRXtc- Dude the Civic Type R is not an LS block with a Type R head....

 

[d-wreck]

man i dont want to dog your idea, but man whats wrong with your b16a.
it reaches a point when you need to just be happy with the horsepower you got. id tune the b16, and just consider it good and dump the money on school or a girlfriend or boyfriend if your female or just into that kind of thing.
if you do it let us know how it works.
you can ask anyone bout that motor and theyll say its bad.
if it was a good idea wouldnt you think honda would have made it. oh wait they did but found that that motor was a pill of crap so they made the gsr. look at the progression of the vtec motors and youll see what i mean
b16a
the b18/b17
then b18c

they were experimenting sorta

derek

 

[jdmb16crx]

Wheeww! I thought that I was the only one in the world that thinks that ls/vtec is a stupid ass idea. I am sure that we could go on for hours about how it not a good idea, but like you guys said above, if you have the money and lots of it (10,000 buks) you can build monster. But if you are looking to spend 2 grand, look at ome other options.

 

[Ultraspeeder]

haha thats funny i dont recall calling lsvtec a CIVIC TYPE R motor? hummmm......good one.....i simply asked a question, and i get flamed.....superhonda is wack!, and YES if built CORRECTLY it can run awesome....trust me ive seen it....but think what u want....have you ever heard of INLINE PRO? aight then look at their cars in think they have an lsvtec runnin some dope times....

 

[ol'skoolrex_PH]

hey guys this LS/VTec thing isn't opinion...

you can easily spend 1200 converting an LS to a VTec motor (not including the price of the motor)... why not just use that money to buy a real VTec that will be much more reliable. the conversion is pushing the limits of the motor, and if you plan to run the motor hard, it's a good idea to make things as secure as possible. JDM1 is just on source that has the first gen B16 SiRs for 1200 and they have VTec.. LS motors run around 500-700 plus the money to drop in the VTec.. cause you know you're gonna pay a shop to do it.. cause if you don't you may as well try to drop a ford motor in your CRX cause man... "It ain't gonna work" but you can certainly have the VTec conversion done so that it will work, but it's just one of those things.. cause you're gonna spend tons of money.. but some people do it just to say that they did it.. if that's why you're doing it.. then go for it.

I had a friend that had an LS/VTec conversion and it never blew up but he had so many little problems with it that he finally scrapped it an bought a B16SiR motor and he's much happier.

 

[jdmb18hatch]

man u guys he didnt flame u he flamed CRXtc and he said hes seen em blow. Ive senn one built right and it still had problems but alot of cars have problems when running 15 psi. its a great idea imo. The lsvtec can make alot of power when compared to all the other honda motors when turboed its even better. BUT u cant do it half assed. teh rod stroke ratio is not perfect but neither is the itr or teh gsr the b16 is the only one that has near perfect RS so do u not build a gsr or ITR no u build it and u build it good. u cant just slap the head on and go u need to do work to it. Phatty has a whole section on his site against lsvtec but crvtec need just as much work and care as teh ls does to run good. If u plan on doin the lsvtec or crvtec for that matter research and save up 2 times the amount u plan on spending cause its gonna be expensive. if u have a b16 stick with it u can make it fast and itll be cheaper in the end. And u already have it if u want to contimplate lsvtec like myself get another car and a b18 and have a spare car. Did i mention a spare car ull need it and a b16 head if ur goin all motor and a b18C head for turbo it will yeild lower compression when paired with the ls motor. thats just my 2 cents and who cares but LSVTEC AND CRVTEC are great ideas.
heres an alternative stroke ur b16 id like to see someone here do that same idea as lsvtec really there is no replacement for displacement

 

[90B16rex]

My opinion. A B16 with a 75 shot of nitrous, can't beat it (reasonably) for $2000 total cost.

Not to mention, the B16 is a superb base motor to start with, handles boost/nitrous very well. The first gen B16's rev to 8500 too, can't beat that.

 

[Phatwhippin_CRX]

75 shot and a B16 swap for 2gs? No way....... the swap itself, if done complte and correctly is about 2500.... at least 500 for the N20 kit..... and a few hundred more for other stuff you're gonna need....... and all gens of B16as all have a stock redline @ either 8k or 8200, I believe....... depend son the ECU.....

 

[90B16rex]

Actually we figured out the cost of the B16 swap at around $1600 total cost, thats with axels, clutch, everything. And yes, its done right. Depends where you go and who you know, I paid $1000 for the motor in excellent condition with the tranny and ecu. and yes, its 8,200, i exaggerated a bit. Motor mounts, are hcp, axels cost $100, and a few other miscellaneous parts, really doesn't cost that much. For $2000 your playing it totally safe, maybe closer to $2200 depending on the nitrous kit.

 

[jdmb18hatch]

b16 1000 if u go to the right place
mounts 410 with linkage
all misc stuff aka wires and such from honda 300 for everyday joe schmo
axles used no good buy new with lifetime warranty then u go to the counter and say here give me a new one 250 if i remember right thats 2 grand right there
plus u may need steering knukles theres at least 100 bucks hey guess wut ur distributer is fried need a new one shit happens
ur not gona runa stock exhaust manifold are u that 300 at least maybe 250 used.. it adds up
plus ur n2o setup phatty knows wut hes saying thats y hes is phatty
and if u dont know the right places to get ur motor its gonna be 1500 cause of shippin and such so 2500 is a good ball park figure to say for the swap cause if ur layed up for days at a time trying to get $$ for a part ur gonna be pissed

 

[90B16rex]

I've put 8,000 miles on it with a stock intake, custom exhaust with cheap tip, and a 75 shot racing it all the time, using nitrous on the weekends. Now its got a couple new things, about 10,000 miles on it and still no problems. Maybe I stumbled accross a way to do it cheaper then you guys. I know for a fact we figured it around $1600 with everything minus the nitrous, and thats not including performance parts, enough to get it in and running solid like i did at first. and my used axles have held up just fine for 10,000 miles, and I saved a few hundred dollars there, and if I break one, oh well, i can replace it and still spend less. And yes, it was stock exhaust manifold too. And no its not a few hundred dollars for wires from honda.
