B18 with B16 head OR B20B??

ermm.. spoon make stroker kits. We have one in our drag crx.

How much kw increase from B20B with B16 head??? what is the budget of this conversion including the B16 head??

my rough budget is $5000 im in no rush to built it its a rough amount to just built a motor block and head complete not put in car i can do that myself thats no problem.

cheers,

unless it is for a drag car where money is less of an option ;)

B20b block + K20A Piston...and B16 or B18 head, with Type r cams and all...cheap and good...Type R manifold and tb as well...and a programmable ECU ofcourse...injector and fuel press is needed..fuel pump and injector ballast...

total cost you less that 5 k i think....piston + rings is cheap...block itself is cheap...2nd hand Type R cams is cheap...get everything 2nd hand except the piston...hmm..may b 5k is already good to go....

use a B20b block, redo the Crank + balance...go for 86mm piston (wats the STD size of the K20a piston? 85mm or 86mm? tell me if it's smaller..hehehe..)...you don't need to go thru the hassle of what ever B20 crank in a B18 block...waste of money...but anyway...I think it all sum up to good workmanship when u considering reliability...

pgclee - pls post any links to people who have used k20 pistons in b series block

thanks :)

thanks for all the info on this ill prolly take my time and build a good bottom end it will b worth the time and money spent.

cheers,

If you're going to resleeve ANY of the above blocks, resleeve whichever you can find cheapest. Resleve it upto 86mm NA or 83-84mm FI

for NA, you cant beat a B18B B20 block at 84-86mm. Port match the head to the cylinders for better breathing (81mm to 84-86mm diameter).

Fact: the ITR cyl head has the same cc chamber as the B16A head. In fact, essentially its the same head.
Fact: the B18B head will raise your compression in a NA combination over the B16 head
Fact: with a large bore engine, the piston dome will not need to be as large to obtain high compression = good thing

So personally, what im saying is, if you're going to the expense to re-sleeve, go 84-86mm, port match the head, high compression, and you'll be looking at close to 300+ whp NA

Cant beat that!

sorry to dig up the dead, but i'm just wondering how much more advantage the b18b head would have over the b16a head in this sort of application? Also, would you be looking at cams as agressive as toda C for example? or something more like CTR cams?

the B18B head is non-VTEC

it has no advantage over the B16A VTEC head.
