Turning a B16a2 into LS/Vtec

[TheBum]

Ok, a good friend of mine has a JDM b16a2. He has cam gears, type-r ecu, and a brand new tranny. It is in a 96 civic coupe.

The problem is: Its not fast enough. He's constantly pulling upper 15's in the 1/4.

My idea is: Since he has the b16 head, why not just get an LS block and put that in place of his b16 block. Run the oil line, and you've got LS/VTEC. Maybe get some new pistons...

Am I forgetting anything, or isnt that all? How much do you figure the block would cost? Also, we know a mechanic who would do the job for a relatively cheap price, but if you have some estimates, throw them at me.

first off if you friend is only running high 15s then he does not know how to drive, why not get someone who actually know how to drive and let them race it and see what it runs. it should be runnin low 15s to high 14s.

its not that easy to do lsvtec, yeah your right when you say you gotta add the oil line but you also have to plug the hole in the b16 head, then drill a hole for the dowel pins on the ls block. you can probably get a block for like $300. BUT if you dont build your ls block up then i would not take it above 7000 rpm because if you do then your ls will only last a few months of racing. i say if you put a b16 oil pump on your ls for more flow adn put the b16 oil squirter on, then buy some cheap upgraded rods and pistons. then your alot better off, but i would still only take the engine up to 7500 rpm and nothing more.

now what if we were to machine and add on to the block to make it more durable. I forget what there was to do to, but when upgrading the block and adding pistons and rods you should be able to rev well above 8 grand, correct?

[civickiller]

the only reason why i say not to take it above 7000 stock ls or 7500 built ls. is because the ls has a very poor lubricating system, its not meant to rev above 7000. that why when people build lsvtec and leave a stock ls and rev it all the way up to 8500, the stock ls only lasts a few months. thats why i say get a b16 oil pump and squiters is because the b16 oil pump is more high flowing so more oil so you can rev it higher. but just building the ls without upgrading the oiling system, you still looking at complete engine failure after a few months

[TheBum]

He already has all b16a2 parts. He already has the entire b16 engine. So i would assume that he already has the oil pumps and squirters.

Anything else that would be needed besides the fully built ls block?

[civickiller]

put the b16 pistons in the ls block, that will yield like a 11.5:1 comp ratio instead of the 9.5 comp ratio if you use the ls pistons. thats like an extra 25 hp or something around there plus minus 5 hp

Dude its a civic, did you seriously expect to just drop in a motor and hit 11's? Geesh :o

dude just in general STOP TALKIN OR EVEN F_CKIN REPLYING TO ANYONES POST ON INfo... lol what kills me is u dont know what kind of car that b16a2 is in? if its a civic sedan? bh? what year? crx? delsol? lol his ls will only last a couple of months without building it up? the difference between an ls and gsr is the stroke is shorter on a the ls, the only thing u SHOULD put in is forged or titanium rods to handle the high revving of that head. and it is easy to do ls/vtec conversion drilling the oil line and drill a whole for the dowel pins is in fact easy if u have an open and knowledgable about engines.. 7500rpm? what in the hell good would it be do do the damn head swap then? thats the whole point to achieve the wonderful power of vtec and where is that that magical 8k redline that everyone likes. oil squirters? what do u mean by this? oil lines? cause i have never heard of this oil squirter unless u made it up or are confusing it with fuel injectors. yes that conversion is a nice one, get some rods and you will be chillen, I would reccomend taking the crank out of ur b16 and put that into the b18 it is made to rev that high and it can handle alot more hp then the stock LS... I converted my friends 94 dx sedan LS to vtec a couple months ago, that thing pulls hard.. plus just extra cool points to say u have it.... lol good luck and keep posting.... EXCEPT FOR CIVICKILLER...

whoa dude i havent been in the forum for a while but i have been looking at posts and you need to chill the fuck out because your giving fucked up info to buddy.

oil squiters exist..please let me focus your attention to the lower right hand corner, item number 28, if you would like to call honda they are called oil jet assembly's.


quik question...why in the hell would you put the crank from a b16 into the ls and destroke it back to a 1.6 liter? i dont belive its even possible to do in the first place because of the deck height the b16 rods would fall a couple mm short. secondly the ls rods would throw the rod stroke ratio out of wack even more then it allready should be, the motor would rev like shit for the angularity and would not be balaced with the flow of the head since head flow is designed to be proportionate to the stroke of a motor.

oh by the way you have the b18b and b18c info a little backwards, the ls motor has a longer stroke

B18A-B:
Rod length: 137mm
Stroke: 89mm
R/S: 1.54:1
Displacement: 1834.47 cc

B18C:
Rod length: 137.9 mm
Stroke: 87.2 mm
R/S: 1.58:1
Displacement: 1797.36 cc

Ok, im getting a little confused with all this conflicting info. Here is what I believe to be correct:

The whole purpose of the LS/VTEC conversion is to take the ls block which has a longer stroke than blocks made for vtec, and use this longer stroke at higher a higher RPM to create more power.

Putting a b16 crank on an ls block doesnt make much sense to me. As ric said, we would be destroking it back to the stoke length of the b16, because the ls crank is made for longer strokes.

Im still confused about putting b16 pistons in the ls block. This DOESNT MAKE SENSE to me. Maybe im confused, but it seems to me that b16 pistons would actually reduce the compression. HELP ME!

sparq, hey THANKS for the useless post! I really appreciate it, you know thats really funny. I mean, no one has every said anything like that before! Thats soooo funny, how you can come up with a line like that all by yourself? Your quite the comedian! You should give yourself a pat on the back :finger:

[SmoovSol]

was referring to a b18c crank sorry, and yes oil jets would be an existing part, that would lubricate the engine internals, but to my knowledge the jets on the b18c and b18b are the same, i just have never heard anyone say oil squirters before. the only difference is in the oil pumps each of them have. I did say the LS stroke was longer didnt I? sorry i typed so fast i see i am missing words now lol...

[civickiller]

i dont not give bad info. you tell me i give bad info but look at the stuff you said. first of all the reason why you dont rev your ls vtec up that high is because the oiling systme sucks on the ls and is never ment to rev above 7000, it doesnt matter if you upgrade the rods because if the rods dont have oil then the motor will sieze.

hey dumbass he said in a 96 civic coupe, go read the original post. so i said low 15s to high 14s because its the jdm b16a2 so it has 170hp with cam gears, type r ecu.

and smoov you went off about the gsr but nobody is talkin about the gsr, only you are. and that b16 crank reamrk, i am not gonna even comment.

so come on smoov tell me one thing that i said that was wrong ? looks like your the only one giving wrong facts

and the piston thing. i dont really know personally i was just told taht putting in b16 pistons will yield that high of a comp ratio. i would give you the site but i dotn remember it. they had a whole list of what pistons give what comp ratio. i know the pr3 pistons w a b16 head yield an 11.2 and the p30 pistons yield 11.4, tahts what the site said
