I'm with eddie, use the LS head, and get a 4-2-1 header of your choice. Some headwork, skunk2 manifold, crower valvesprings & retainers, cam gears, and some crower 404's. Throw a GSR tranny on that, and it'll be decently quick. It should be said that whether or not you use the LS head, you have to use the LS intake manifold since the B20 has the "giraffe" intake manifold.

If it was me, I'd either go turbo, or the above setup with some juice But I'm a nitrous fiend h:

 

thanks for the advice guys. I think I'm gonna stay all motor for now cuz im not even manual yet so it'd be a waste and a hazard (mis-shifting). If I move to texas I will most likely turbo it there, but for now I'm good. I might have to keep the b20 head for a while while i save up and have my ls head built and then put on. But yeah i have good insight now and goals to be accomplished. So hopefully all goes well with that x-member cuz i do plan on putting in a DC 4-1 header. Thanks again guys.

 

I would go 4-2-1, especially on an auto.

 

throw on a gsr head h:

 

auto B20??? :happysad: at least you'll beat other auto LS's
skip the boltons and LS head, get a GSR tranny swap.

I/H/E = $600
LS head stock = $100
head port and polish = minimum $100
cam gears = $60
plus labor for install if you dont install yourself

or

GSR tranny = $600
LS manual ECU = $100
plus labor for install

tranny swap is WAYYYYYYYYYY more worth the money and performance than boltons and a semi built head on an automatic teg. plus you can swap in the tranny while doing the engine swap to save more time in the future.

 

A good port job is going to be upwards of $4-500

I'm with eddie on the tranny swap.

 

How would the stock LS block be with the B-20 head. Would it be an improvement if ported and polished. or a waste of time

 

I agree. Screw the automatic, it saps the living bejesus out of the engine.

 

Holy thread revival.

B20's suck, end of story.

 

'Specially since K20 is the way to go nowadays...and it isnt all that much more than the B20, and you get more options and more power. But, I mean it's totally up to the customizer, I'm def. not bashin anyone havin a B20 in an Integra!! I have to do some work to my B18 with 150xxx miles on it, and in my opinion, the work is worth saving the engine, even tho its only a B18.
