I have a free b16a2 head sitting in my garage.Thats right free.I was going too put it on my ls,just one thing.IM BROKE!!!I cant afford too have my motor out of my car.I was wondering what kinda hp am i going too be putting out if i put the head on the ls and have i/h/e.I would also keep the stock redline because i dont want too risk anything.Thank You

 

anyone please

 

you cant just expect to bolt on the head to the LS block and be dandy and ready to go...

be ready to spend some extra money but if i were you

wait spend the extra money and do it right the first time

 

lol,ya buddy i know how it works.All i need too know if how much power at 6800 would this make?There is no damage too the bottom end under 7k.Im just debating if i should sell the head and go with non vtec all motor with 404's or would this head put out more power stock

 

I'd keep the head, save up for some ARP rod bolts and head studs, JDM ITR pistons, Golden Eagle LS/VTEC conversion kit, VTEC oil and water pump and other stuff you'll need (new bearings, seals, gaskets, belts, etc.)... pretty pricey if you add it all up but definatly worth doing it right the first time, imo.

Unless I missed something, that should be a pretty decent LS/VTEC setup. I'd think you would make much more power than an LS with Crower 404's too.

 

"Do it right or dont do it at all"

...has always been a good one

"Do it right the first time so there wont be a next time"

....is a good one too

 

lol will someone just answer his question, cuz i need to know too. stock head on a stock bottom, what will the hp be? i was told 170 by a bunch of people inclusding a shop, just wanted to confirm.

 

were you planning on running the VTEC? Or were you just going to swap the heads for better overall flow. Either way you will have to cough up a little money for a new head gasket and some ls/vtec dowels (don't try to drill it). If I were to guess I would say no more than 160 just swapping the head.

 

I would count more on 140 to 150 with a chipped ecu.

 

stock ls/vtec would probably produce around 140whp and about 115-120lbs, its a low compression setup so dont spec nothing high,my friend tried this setup a while ago and at top end def felt slower than his b16 sir2, torque was improve though,but once you add some high comp pistons jdm itr or ctr then expect those numbers to jump.

170 is way off!! IM running a Stock B16 head with GSR cams on a Stock LS block and chipped P28. I dynoed at 153hp. 115 ft tq. It made a difference from the Gude LS head I had on. Ive been running this set up close to a year autocrossing and drag racing all the way to 8k.

 

Here is a video of my stock pr3 head w/ gsr cams on a stock bottom end b18a

Anyone know if skunk2 stage 1 or 2 cams will work with the stock ls bottom end?I heard that there might be valve contact???

 

Why would the torque be lower also then a stock ls?

 

I wouldnt run the skunk2 cams. Your compression is way too low to make any kind off power.

 

stock ls puts out 110lbs of torque, with the 9:5 compression of your stock ls/vtec neither skunk stage1 or even worse stage 2 will give any decent hp gains even worse with the small ls pistons valve reliefs, pistons to valve contact will def be a problem.. best bet would be some gsr cams for that low compression.

Reason I have mines!!

 

my stock ls bottom with stock b16 head with gsr cams made 162hp and 132tq with muffler shop exhaust and homemade intake, with jdm b16 exh. manifold... so u cant just tell someone what they will put down it all depends on the engine....

and keep in mind u have to buy a distributor to go with that vtec head. and intake manifold if u dont have one...

Must be a wednesday motor!!

 

why would anyone want to run the stock low comp pr4 pistons
the absolute and i mean the 100% absolute least that should be done when building a lsvtec should be
arp rod bolts , head bolts, pr3 pistons or p30, vtec oil pump , vtec waterpump and timing belt.
yours still going to need to get all new gaskets and houses, ls headgasket, lsvtec dowles, lsvtec oil line
also dont forget machine work
lsvtec conversion which is the machine for the dowl holes for the head to to plug the current vtec oil passage, and another $50 to resize the rods for the arp rodbolts.

expect to get around 150-160whp with this set up

if your really just going to go cheep and do nothing and keep the ls vtec line with the low cr dont expect much power at all
expect 130whp if that with a stock lsvtec with only 6,800 redline

I have the same setup as your "thinking"

and Im running 130whp on 50 grade oil, chipped ecu..

the cars have such low compression which is why honda never made 9.2:1 vtec engine..

you might want to get CTR pistons, and skunk cam upgrade.. then youll be looking at 150-70whp

 

been awhile since i have been on here.. but its funny if u think its bullshit... i have no reason to lie about the number i put to the ground.... if it wasnt 2.5 years ago when i did the dyno i would post the graph.

and talking about compression.. just because a ls engine is 9:1 compression does not mean it will be the same when u put on a vtec head.. 2 very different combustion chambers.. so depending on the head the compression could be anywhere from 10:1 to 10:8 my head that was on my car was milled alittle to end up with a compression ration of around 10:5:1...

my engine was a wed. motor it was assemble by dfe enterprises (donf is his name on here) he can vouch for the numbers the engine made..

btw the engine is still running after 3 years of abuse..

hotintegranights is just ignorant and knows nothing about engines.....
