new b20 for my 1990 gs

Just bought b20 for 90 teg gs. Should be ready wed just the block and head are going in for now i no it has more Hp but will it be noticeably different than my b18 a block and head and if so how much different also what are some things that I can do to increase Hp minor things for now that is

Also what about smog for car now

Which b20 is it? Depending on which one you got (where it came from) it may actually be less powerful HP wise.You will feel a bit more torque though.

The b20 is really similar to the b18, aside from increased displacement obviously. There is only so much you can do to get power out of them without spending a lot of money... intake, header, exhaust are the starters, but then you have to start spending more money to do things like vtec conversion, cams and valvetrain, injectors, tuning, building the bottom end... Eventually if you're looking to go beyond 200whp you'll need to boost it.

PS, please use punctuation, it makes it a lot easier to understand what you're asking. :thumbsup

It came out of a 2001 crv all wheel drive it should be the high compression one right

Vtec head swap is that what u mean

All B20s make more power than any B18a/b.

So is this gonna make a difference that I will notice

Unless you run the correct map for a b20, probably not much of one.

Map what do u mean. Map

Basemap, the stock fuel/ignition tables for each engine. Your old b18a has a different one than the stock b20b does.

If you consider 9.6:1 high compression, then yes.

96-98 US spec B20b made 126hp. That's 4hp less than US spec B18a like our friend here had, albeit they make more torque (133tq vs. 90-91 US b18a making 121tq). I guess it depends on how technically you want to look at it :what:

Technically speaking, that number you posted was through a crappy automatic transmission and a different intake manifold. :what:

Correct. That giraffe neck doe.
