Can Someone Clear This Swap Up For Me...
 

I'm tired of my turbo d and i'm planning on just getting a b16 or b18b. I had a couple of questions because after doing some searching, i am reading all different answers. This swap will be going into my 1997 Civic EX Coupe

1. Will the b16a1 and b16a2 directly bolt into the car with no modifications?

2. Will the b18b a direct bolt on to my car?

Any other help would be great since this is a DIY project for myself and it's my frist time swaping motors.

b16a1 is 1st gen b16 obd0 I think. You don't want that.

b18b will fit, but you need a p75 obd2a ecu. You'll also need to do some rewiring and use the civic harness with a couple plugs from the integra harness. You need a rear motor mount and the part of the mount that bolts to the block on the drivers side of the motor and a power steering pump all from a 99-00 Si.

b16a2 bolts right in i beleave except minor wiring touch ups. ie. Vtec wiring and ecu also you need the axles from a 99-00 si

Re:Can Someone Clear This Swap Up For Me...
 

he has an ex, he already has wiring for the vtec, and i doesn't bolt right in, you need the mounts rear and driver side mount from an si like stan said ;)

hmmm...doesn't seem too bad. Everyone's been saying it bolts right in since i got a coupe and the b16a2 came out of a coupe. hmm...i guess i'll lean towards the b16a2 over the b18b for convenience

b18 is faster though. If you want power,a little extra money and time go a long way. Just a thought. My friends 4 door runs a 14.2 in the quarter with a b18 turbo. Thats fast as ---- for a four door. Just saying if you want to go fast go with the torque.

Re:Can Someone Clear This Swap Up For Me...
 

really? I know it has more torque than the B16 but am not sure about the B18 being faster than the B16. B18 more torque. B16 more hp.

But if you plan to boost... I'd get the B18... B16's high compression is a pain in the ass.

Re:Can Someone Clear This Swap Up For Me...
 

i'm planning to just do the basic bolt ons. My turbo d was fun enough, but i just want to get something reliable and not looking to turbo again. So would the b16 be better for na or the b18b?

Re:Can Someone Clear This Swap Up For Me...
 

and dont froget the axles from the 94-97 sol.

Re:Can Someone Clear This Swap Up For Me...
 

ahhhhhh hp is torque over time

i hope you're talking about a b18c, because a b18a/b is not "faster" than a b16, bottom line, the b18a/b may be able to handle a little more boost safely due to the lower c/r, but if you boosted the same amount on a b16 as a b18, the b16 would make more power, just like it makes 20 more h.p. in stock form compared to the stock b18b and 30 more than the b18a, the only thing the b18a/b has that the b16 doesn't is a little more torque, but that only allows it to be quicker about half way through first gear, then it's the b16 all the way. i've owned all three engines, so this isn't an opinion, these are facts.

b18 gets spanked by a b16a

Re:Can Someone Clear This Swap Up For Me...
 

If you're talking n/a, b16 is the better choice.

im just an ass who likes to talk alot but ive seen b16s lose agaist sr20des and those my friends do not have vtec there similar to a b18 more displacment a little more torque this is my own personal thought im not saying the guy whose owned three is wrong im just saying vtec kicks in and operates up high b18 the torque is there good driver might be able to take b16 with a b18 but then again what do i know

Re:Can Someone Clear This Swap Up For Me...
 

Here's a novel idea: B18 block, B16 head.

Any thoughts?

Re:Can Someone Clear This Swap Up For Me...
 

we call this LS-Vtec

Re:Can Someone Clear This Swap Up For Me...
 

How about B20/B16 head. Hmmmm? That sounds fun. I don't know what to compare that to. But if you do that with a turbo you should have it sleeved. Or just start off with a b18 and sleeve it for cheapness. That would be nice. That will be my next engine after I turbo this z6 and blow it up. I hope I don't. It's my only car.

Re:Can Someone Clear This Swap Up For Me...
 

i'm not interested in ls-vtec....heard there's just too many problems.

i just want something reliable that has some power

Re:Can Someone Clear This Swap Up For Me...
 

just get whatever B-series engine swap that you can for a cheap to good price. You'll be happy with it if the engine is still in good condition. At the end, it just depends on what you do and what you like.

Like they said already...

B18 will have more torque
and the B16a vs the B18a, B16a will have more hp and the B18a will have more torque. If you want the best of both worlds, b18c

I'm sure you'll be happy with whatever B-series...

Re:Can Someone Clear This Swap Up For Me...
 

when people say it bolts right in they mean using OEM Honda Parts from a 99-00 Si. This swap should be cake. just get a obd2 motor and obd2 ecu and you're good to go.

Guys I recently bought an 00' Civic DX NO VTEC. This car is weak and whoever I bought it from cut the harness for what looks like no reason. Maybe the engine was stolen and they didnt want to deal with unplugging everything. I am looking to swap to a b18c but I am afraid of boosting it due to the high compression. I heard the head from a b18c and an LS block are a great combo for turbo applications and I want to run about 350 whp. Is there some other option I should be looking at that will still be safe and run a low c/r?

Re:Can Someone Clear This Swap Up For Me...
 

the swap is a no brainer...has anyone ever considered that the y21 trans found on b16's has a a higher final drive and a closer gear ratio to compensate for the lack of torque.

Re:Can Someone Clear This Swap Up For Me...
 

Ok, all you guys are mixed UP!! B18 sucks because it has no vtec. When you here vtec kick in on an N/A DOHC...it's like no other.

B16a will always beat a b18a/b unless the b18a is in a significantly lighter car w/ good driver. It is just plain and boring with b18a/b because you have to shift at 6,900 rpm, also no vtec, who cares about the 10 extra lbs of torque.

And he said he doesn't want turbo...and LS-Vtec is not good for turbo because the compression for an LS Vtec is generally even higher than a b16, unless you plan on buying some aftermarket low compression pistons.

Re:Can Someone Clear This Swap Up For Me...
 

dude b16a or b18c1, you will never be happier when vtec engages, it sounds sweet nothing like puny sohc vtec that u cant even hear.. ::) if u want the b18 it is cool but it defintely isnt a b16a...
