do you think the b20 block with gsr head/tranny is the best of the motor ? Cause I have the b18c1 engine into my 95 honda civic ex, one of mine friend told me to get the b20 block, do u think should I get the block?
help!

just give me a little advice thanks!
 
oh no, here we go again.

It's not a bad motor, it just has to be built correctly. Judging from your 20 page thread, if I were you I would have a reputable engine builder do it for you.

Of course you could just rebuild the GSR and bore it out to 84 mm and have a 2L GSR.
 
I'd get the B20 block and just put the main girdle from the GSR into it. I wouldn't bore the gsr to 84mm. You're taking 1.5mm of material off the cylinders to do that and I just wouldn't trust it.
 
Technically that's exactly what the b20 is, an LS bored to 84mm. The sleeves are weak
 
in my opinon, the b20 was non-vtec for a reason just like the ls, keep your gsr, just my input

just to be considered, there are many people who will disagree with me

Yes, like me. :)


Get the b20 short block and have a machine shop build it. Keep the stock bore of 84mm. Upgrade pistons/rods/rod bolts/oil pump/water pump/rear main seal. Buy a b20/vtec conversion kit and new ARP head studs, oil pan gasket and valve cover gasket.

Girdle's don't really help all that much. Also, he will be boring out 3mm, not 1.5mm being the gsr has a stock bore of 81mm.

Yeh I know that the b20 was non-vtec, But the b20 will get a vtec instead non-vtec if i put the gsr head on the b20 block, That's what my friend told me.. But I don't know if it is tru, That's why I am here to get some little help.
 
Which is the best JE or CP pistons ?

Hahaha. You really need to do some actual reading. :D

Yes, putting a VTEC had on a non-VTEC block will give you a VTEC engine. However, the block wasn't designed to operate at a VTEC engine's power band so you need to make a few modifications. Those modifications are very easy to find. You could try reading some of the two or three dozen other topics or even look in the Reference Section for the how-to guide.



Um...what? With the exception of the B20, all B-Series engines have an 81mm bore. The difference in displacement is from the stroke.


Thankkkss very much for the information!!, just want to make sure, if my friend aren't full of CRAP LOL..

One more thing, In your opinon which would u like to have all stock gsr b18c1 engine or get the b20 block with the gsr head vtec on it ? Curious :p
 
You will never see me with a stock b18 anything though. :) As far as ls/b20 vtec's, if I go that route, it is with a built bottom end. First things first you know. They don't call me the compression king for nothing. :)
 
Does b20 block have an 91mm bore? Wondering.. Cause my friend told me the b20 block have 91mm bore..

But I already know all b series engines have an 81mm bore.

All B-series engines except for the B20 have an 81mm bore. The B20 has an 84mm bore.

So once again, your friend is a fucktard...
