is the block the same as the b16, b18 's?
which is better to start w/, b20b or b20z?
if i go w/out vtec for awhile, will it interfere w/ the ecu (wierd codes, etc.; since my car has vtec now)
what ecu to run?
is it the same swap as the b16 & b18?
how hard is the wiring to do? then to switch to a vtec head later?

im sorry for all the newbie questions, im just looking for some help. if anyone has any step by step stuff on this swap it would be much appriciated. i spun a bearing in the old d16z6 and im tryin to explore my options and the b20 sounds good so far, just lookin for swap info. thanx.

 

search?

 

Same block as B18A/B except 84mm bore instead of 81mm
Either and bore it .50mm over with forged pistons
Won't interfere with any of the wiring. With the VTEC motor you'll want to have VTEC, VTM, KS and any other related sensors wired so that later you can just plug them in. It will afftect what ECU you wanna run. Either LS for nonVTEC or VTEC ECU (I don't know what year or car you have)
Basically same swap as doing a GSR or B16 swap anything VTEC related if you are doing the wiring.
The wiring is easy (I still don't know what year or car you have)
Header is really easy to switch later unless you have a CRX, 4th Gen Civic, or 2nd Gen Integra.. at which time you just have to remove the front crossmember.

Basically we just need to know what kinda year and car you have.. A lot of things change in the wiring depending on what car.
