So ive been debating on doing a swap on my 98 4 Door. It has a D15b Vtec right now(Y8 head), and is alright but im lookin for some more power. I was thinking about going with a B20b for now and later swapping a B16 head on it. when im looking i see a couple different B20b's. I see the 2 with the short intake manifold and one with a longer intake. I understand there's power differences in each but on one site i see it listed by intake manifolds and Hmotors does it just by the power. So which one has the long intake manifold the one with the P8R head? Am i going to have a problem if it does come with a long intake manifold considering its going in to a civic and not a teg? or should i just go ahead and do a B16a? Thanks guys please help as yall were so helpful when i was doing my first swap last year.

 

What are you looking to do with the car? Do you just want more power?

 

Yea for the most part. My orginal plans were to do a B16a and make itlike a 4 door Si, Cuz i found tails that r like Si's and the front end is being worked now with new headlights, fogs and diff grill. but i was thinkin about B20 cuz i only know of 2 people around here runnin them and no B20v that ive seen yet.

 

And i dont wanna boost with out a back up car.

 

b20b swapped last weekend in my 96 4 door with gsr tranny. a lot more fun but ran into a computer issue yesterday, stuck in limp mode but i recommend the b20

 

yea really been considering it but i dont wanna lose Vtec lol. which B20 did u use?

 

I see you're in VA. The B20 is classified as a "small truck" motor, and thus is an illegal swap in our cars in our state. You probably don't care, just thought you should know. I know the cops are royal ******** out there at the beach.

 

o wow really i didnt know that. but whos gonna pop the hood and see it? i know people with B20's that pass inspection with no problem. never heard of that law or anyone ever being charged with swappin a motor.

 

If the cops are in a particularly shitty mood, but even then they'd have to know what they were looking at.

Basically, just hope that they don't start smogging at the beach. They talk about it every damn year, but they never actually do it.

 

I have a GSR in my EJ8 and it came with stock small headers, then i got some long DC headers and got my exhaust piping done with a BuddyClub pro muffler.
the cat will be pushed a bit to the back

 

i got a b20z2 and from wat i understood there a higher compressed motor and it ur doing an all motor build like my self then its the better motor

 

If you're doing a real all motor build, it doesn't matter if there's a higher compression motor available - you can replace the rods, pistons, and valves to change the compression.

 

i have the b20b high cr block. if you are doing all motor the b20b is the best bang for the buck. i have a 94 civic with b20b and gsr tranny fun and fast to drive. right now is bone stock with intake header exhaust combo. coming soon 250whp 230lds torque keep u guys updated.

 

If you get the b20 with the longer intake which i believe is the 96-98 spec b20b4 then just swap it out to an LS intake so it can clear the hood. You will have use a complete LS intake with fuel rail and injectors though.

 

hows the build going?

 

Yeah the long intake is a bad idea you won't be able to put a hood on it trust me a just got a b20b with the long intake get the short one to save yourself some trouble lol

 

I'm sure they would have appreciated that comment 4 years ago.

 

@ b20ek9 unrelated question for you: I have an engine the same motor that I pulled out (incomplete build) of a 1990 EF wagon. The transmission label is missing. Any idea what transmission it could be?

 

Discovered it's a Y1
