I'm just curious to see what you guys think. I know the B20/VTEC is a very popular combination right now, and the premium you pay for a B20 longblock reflects this. I think the cheapest I've seen a B20 block go for is about $800 (ouch). Maybe I'm just shopping at the wrong scrapyards!

Anyway, what is the big deal about the B20/VTEC setup that makes it so much more desireable than say a 85-87mm bore pure B18C1 setup? At 85mm bore, that would put you at 1979cc. Almost 2 liters. At 87mm bore (max Gold Eagle bore for N/A setups) that would put you at 2073cc! Golden Eagle sleeves are less than $600 and you end up with a block that's way stronger than a B20 -- for less money.

So what's the deal?

 

remember that motors make torque through stroke too, i would do a b18c1 because of the much better crank and shorter stoke, remember that the LS/CRV cranks are not made to rev as high as the cranks in hondas dohc vtec motors

 

i dont think there is a deal...

a sleeved 1979cc b18c would toast a B20VTEC anyday...

t..

 

so what does a B18C block go for if it's so much cheaper then doing a B20B?

 

i think cheezefrog may have assumed that the debators may already have a had a B18C lying around...

I think a lot of it depends on if you plan on keeping the stock displacement on the gsr. If you don't mind going 84-85mm bore on the gsr, i'd say go for that.

 

it takes 7-10,000$ to build a b20vtec CORRECTLY.

 

I can vouch for that price range. My b20/vtec motor built by importbuilders with everything needed for the swap cost around $7,000. I don't know how reliable a b20/vtec motor is but once everything is installed I will surely post on h-t tech if anything happens.

 

KAMiN :- i have do disagree with you there . used your term CORRECTLY properly .

It doesn't cost $7000-$10000 to built a CRV-VTEC Correct. it cost that much for a all out race motor . Because i am in the process of puttin together one of these motor ( pistons , rods , mild headwork, skunk2 stg2 cams ) and my motor is being sorted so it runs good , and in total i have not spent that much .

$7000+ or not ...... if it is not cared it'll blow ..... so i don't mine all the BS about correct ....... because if i put up my motor and a guy spend that much on his and he drives his hard 24/7 he'll destroy his motor faster than i will even tho he spend he pretty $7000+ .

so that amount doesn't mean his sh*t is correct ............. it is build by mankind , it's not %100 perfect

 

Unless it has "Type-R" written on the back

 

Perfect example to why posting on message boards gets really annoying. People dissecting every singe word you type. It was difficult to understand the point "eg6madness" was trying to make, lack of spelling/knowledge of the english language.

Anyway, I think $7,000 is a pretty normal/resonable RETAIL price for a "well built" b20vtec setup. Of course not everyone pays retail.

 

not everybody wants a fully built race motor. you don't need all the highest priced parts to make a good running b20vtec. you could build an engine with decent power with all honda parts for less than 7000 and it would still be a good engine. alot of people just want a fun daily driver. not everybody wants the DOMINATOR setup.

 

Thank you very much rookie2nr ......... at least someone saw my point .

oh yea ..... sorry NOBODY ...... everybody can't be a sagacious dolt like you are . ( since you are such the English adept , you know what that means ) . My bad english earlier was due to the fact that i had just woken up ( i don't live in the USA ) and i was still ignorant , so i typed a load of crap . But i am glad the you being the kind-hearted person you are was able to amend my imperfections i had previously posted .

Thanks

**PS did i mention that the country i live in is an English speaking country , and that i have a Degree in English , (as well as Mechanical Engineering) . If i didn't , i just thought i would enlighten you **

well, my budget for the B20VTEC i am building is around 1500 for the block, headwork, ARP fasteners and swap consumables,

i am leaving the internals stock except for the rod bolts.

i believe that i am doing it CORRECTLY.

creating a daily driver with plenty of torque and VTEC.

i could have gone with a B18C for a couple of hundred less, but i like to be different and i will certainly enjoy the torque down low...

my 2c

tinkerbell :- not meaning to argue with your setup or anything but you say you are leaving everything stock . But don't the pistons and valve have a problem when VTEC is engaged ?

I heard the reliefs aren't big enough !



[Modified by eg6madness, 1:28 AM 8/13/2002]

 

argue away my friend...

yes, it is often said that the valve reliefs are not big enough.

but there are no horror stories i have hard where reliefs wernt machined and there were clearance issues.

teh difference is probly about 0.25 to 0.75mm in actual distance(the VTEC valve is 1.5mm wider), and hte B20B pistons are more dished than the B16A ones...

so, i will be putting it together and claying it anyways, however - i doubt there will be issues at all,

even with a 1mm milled head.

give me a few weeks, i'll let you know.

t..

PS im not leaving everthing stock - ARP rod bolts/head studs, oil cooler, PCV system plus more...

 

thanks for caring.

 

I can vouch for the $7000+ price range on the Import Builders CRV/Vtec setup, as that is what I'm going with.

 

wow, i couldnt even consider spending that much on a motor all at once. i just spent 1800 on my b18b swap. im gonna turbo it and later resleeve,forged crapola.
1800(swap)+800(GE)+350(rods)+450(pistons)+3000(tur bo crap)+450(hondata)+500(extras?)+650(other extras?)=8000

and ill be doing that over a loooooonnnnggg period of time.
what is expected from that 7k b20/vtec setup???

you bastards with your money!

 

My motor has a built bottom end with 11.5 compression, and my head is a stock b16 with an aem fuel rail, 440cc injectors, and Type R throttle body. I don't know how much power the motor is going to make with the b16 head, but I hope to be around 200whp. I will dyno the car once I break in the motor and hondata is installed.

 

$7-10k for a B20/VTEC? Man, ImportBuilders must be resleeving their blocks with gold or something?

 

If you break down the parts and prices (Of course they add their own labour) then you'll see how much its costs.

You can throw parts in there (Forged rods and pistons), but to make sure you've done everything you'll want to balance the whole assembly (Why not blue print and re-sleeve). It works out to be the same. If your going N/A I don't really see where the gains are (A little more tourqe, more money spent and for some a bigger headache). Boosted would be good but if you are going to building the block then it really doesn't matter which block you go with (For ease of installation keep it all non-vtec or all vtec because after boost it really doesn't matter).

 

B18C1 is the BEST all-around motor right now, that is why almost everybody has one in a hatch. how many people do you know that have a hybrid with a b18c1...i know about 6 that have one and about 4 more that want one (including my bro) and that is just the ones that are around Knoxville that i know of.

i figured WTF i want to be different so i am going b20vtec. there are 0 b20vtec's around here and maybe 1 or 2 lsvtec's.

i will have about 5k in my complete drivetrain and that is to put it into a crx. that includes forged pistons and rods, itr outer v springs and portflow inners w/ ti retainers, brand spankin new '01 itr cams, directport NOS, a 2/3's rebuilt 93 gsr tran and a bunch of other stuff. however, i did and will continue to do all my own work.

 

...I wonder why? Cuz most of em broke down already! j/k

Good luck on the buildup.

 

I was just thinking the same thing last night too...its like u read my mind... i have a turbo b20 in my car and the torque is insane...but the top end sucks...my car is getting sold today...i already have another project...i was wondering if a turbo b18c with an 85mm bore wouldnt pull similar numbers to a turbo b20 vtec.... theoretically it should right??
