i want to know which would be easier?? cheaper?? and more powerful??
ls/vtech or gsr?? i might go boost also.. depending on if i feel i need more power..
i have an ls in my hatch right now, so would the ls/vtech be better??

LS/VTEC considering you already have the LS block.

LS/VTEC.

 

thanks... i have been thinking about ls/vtech for a while now.. but i want my block redone.. which would be better to use? b16 head or b18?

B16 is the best head to use. Suprisingly, although it is only a 1.6 l engine, it flows alot better than the B18 heads.

I wouldn't say it flows "alot" better. The b16 has a slight advantage at higher lifts but that's it really. Either one will work great, gsr will give you more compression, but b16 are usually cheaper and easier to find.

1st gen B16 heads are a little different than the new ones but they are usually a lot cheaper....

???????

Wow..

B16 or PR3 is also the EXACT SAME CASTING as the ITR/CTR (PR3) ALL of the B series Dohc Vtec heads are the same except for the GSR, which is a design of its own.

Now you know, there are only 2 castings used for DOHC Vtec B series Heads, a Pr3 and a P72. They each however recieve different valvetrain, cams etc.. and the Type R's have a factory Port.

Now any of the Dohc Vtec heads will greatly out flow a LS Head.. Or B18 Non vtec stock for stock.

 

gsr is a superior all motor engine, small combustion chambers = higher compression and the quench area flush in the head. plus newer castings. Go gsr imho

 

I've always heard that using a B16 head is preferable. That's why a GSR with B16 head was referred to as a poor man's R, right? Or am I wrong?

 

LS/VTEC but do it right cause if you scimp it'll pop

The LS/Vtec is the poor mans Type R. Also, I had a friend who did test with the GSR and B16 heads on a flow bench to find out that there was not a drastic difference like others thought some time ago. The B16 head tends to have runners that are more straight as where the GSR runners have a little angle to them. Other than that the GSR has a different style combustion chamber which creates more compression.

 

thanks for all of the useful info... now i just need to find out all the things i need for the ls/vtech.. since i heard a lot of people mess them up by skipping key details..

Its not hard but you definetly dont wanna leave anything out. I think Golden Eagle sells a LS/Vtec conversion kit but dont quote me on it. Another thing to remember is if you want a reliable LS/V build it right and like you said dont cut any corners!

 

well im going straight ls(gsr). i got the block, crank and head is on its way. just make sure you build it nicely if you plan to add power to it later on. im doing a complete rebuild with forged internals, and a ported and polished head. along with a nice sized snail.

 

its cuz the gsr head forces u to use the gsr intake manifold or a expensive skunk2 or similar.

b16 head + b16 IM = way cheaper solution.

 

ls+vtec+boost=fast as fuckkkkkkkkkkkk. have a nice day

 

i dont know where tippyman is getting his info but some of it seems to be wrong like the LS/VTEC more powerfull??? not true take a completley stock b16 or GSR head and put it on a compltley stock LS block i guarentee it wont be more powerful than a stock GSR , and like said before the b16 head is not the best actually more people prefer the GSR head over it due to its CC design.

 

X2 and for the SiR head people take that head cause you can find it every where. The GSR head is harder to find.

 

i thought your CR will drop if u put a b16 head on a gsr block. i thought you had to put type r pistons with a b16 head and tranny on a gsr block to mke a poor mans R

yes it will, unless you mill the head/ and or do the ctr setup.

Ok, lets clear this up as well. The type R motor consists of the pr3 (b16) head, which has a mild port and polish along with different valve springs and retainers from factory. Thats why it is considered a poor man's R.

Now if we're talking an all motor car, GSR, if poormans R, b16 head and get some headwork done. etc head is good.

 

im pretty sure its a proven fact that b16 heads flow better than a gsr. and if you do get a 1.6 you have to rock the sirII head they are way better than the sirI p.o.s. But if you want to make more power than the ls/vtec or the gsr then do a b20vtec no replacement for displacement

the only thing thats bad about the b20 is the cylinder walls are a lot thinner then everything else...do it right, get it sleeved

 

Just using the classifieds here, you can assemble what's called a "poor man's R." It basically uses a GSR block, and a B16 head. The head internally being made of Integra R parts.
