I heard that B16s are better to boost and It seems like most tuners have B16.Which engine is better to boost and why?If B18 is bigger liter than B16 then I don't see why more tuners choose B16.Is there a big difference in price?

 

It's all a matter of preference, price, fuel efficiency, and availability. I would think that the B18 would be better for turbo because of the bigger displacement, but i've never experienced it myself so i couldn't tell you for sure. B18's are considerably more expensive than B16's, plus the fact that most of the B18's are OBD2 which makes swaps even more expensive because you have to do the conversion to OBD1 if your car is OBD1, or OBD0... etc. That's why you see more b16's out there.

 

Oh I see.Do most people boost DOHC instead of SOHC because the DOHC can handle more pressure or is it for the extra horse power you get with DOHC?

 

b18b's are pretty well known for their compatibility with boost. I'd go that route.

Maybe even a LS/VTEC setup, too.

 

I have seen more boosted d-series than b-series engines.

 

mix them

False, False False....

B18A1 and B18B1's are MUCH cheaper than a B16. I picked up my first B18B swap for $750 total cost *it was a 1996 OBD2 motor to boot* and it bolts right into, and PLUGS right into any EH/EG chassis (1992-1995)

My SECOND B18 swap cost me only $500, and was a 1994 OBD1 motor, again, plugs right into EH/EG's

You need to convert things if you are putting a B18 into a 96-00 Civic only.

As far as B18's holding boost better, they 'hold' the boost better,and respond better to it, B18A/B motors have a fairly low 9.1:1 CR making it safer to throw 12-14PSI of boost and easier to tune opposed to the high compression B16 motor.

Also, B16 rods/pistons are lighter because they are designed to withstand high high RPM's but thin rods and boost don't work well spinning to 9000RPM, while the B18A/B motors redline at 7000 and have fairly thick rods.

as far as 'seeing' more B16 swapped civics, I dunno if thats really true, because remeber the B16 was only sold in 2 cars in the US, both were limited production, so the vast number of 'b16 swaps' you see are imported motors.

I feel you see more 'b16' swaps because they are cheaper than GSR swaps, and LS swaps are still growing in popularity due to their low cost.

B18c1 Block with a B16 Head or u can also go Boost on a LSV, my old setup was LSV. ANIMO

 

if you build up a b16, they can have a lot of power.. in my opinion i think that a b16 is a good motor, since it is DOHC VTEC and with a few parts it can be a really strong motor *rods etc.* LS are cheaper, and you can add a VTEC head later to have LS/VTEC, which do handle boost pretty well too..

 

good question...always wondered the same...

yeah dude, i know i know i know. i was referring to the GSR b18c. my apologies for the confusions. hmm... i could have sworn a buddy of mine had to do a **** ton of wiring harness mods to get his OBD2 GSR to fit his 93 hatch. around here almost every civic i see has got either a b16a or a boosted d-series in it.

I would go for a b18c1,

Thanks for being understanding about it! Yea, GSR's are usually 2500+ for the swap which is anything but cheap.

the shock-tower harnesses on the 92-95 Civic and all 94+ integras are the same, I suspect he hacked up the civics wiring harness to try to make it work/reach everything on the GSR motor, and I also suspect since his is a 93 hatch it wasn't an SI so he had to wire Vtec all the way back to the ECU also.

For the 1996 B18B1 I put in my car, I just used the harness that came with the motor and it literally plugs right in and starts. if I bought a GSR motor, it would be the same way with the GSR wiring harness because I already have Vtec wiring to the shock tower in my car, but if I didn't I'd have to wire 2-3 wires back through the firewall to my ECU which still isn't a big deal IMO.

 

indeeeed. anyways fryman, sorry for going off subject, hope ya got the info ya wanted.

 

this is an endless argument that could last for centuries, its all about which one you prefer

 

i read an article today in honda tuning about gettin 500 HP off a stock block, and mostly a stock head as well... i thought that was interesting...

 

i have a 94 civic sedan with a 97 gsr motor and i had to wire in a knock sensor and the vtec and change the ecu other than that it fit right in its all on how much you are willing to spend. b16 are a good cheap swap and a lsv is even better if i were to do it again i would go lsv

Whats ls,lsv,gsr,shock-tower harness,si,OBD1,OBD2?

I'm pretty new to the forum so I don't know all the Honda lingo lol.I know OBD has to do with the wire harness though.

By the way when you put a DOHC in a car built for a stock SOHC,what all do you have to change in the car?I heard you have to put in a new transmission and drive shafts.

 

an ls is an 1.8 non vtec a gsr is an 1.8 vtec an lsv is a non vtec block with a vtec head the she shock tower harness is the three plugs that seperate the car wiring from the motor wiring. si is the model and options on the car and obd0, obd1 and obd2 seperate years in the cars so if you swap motors from a 92-95 into a 88-91 you need to change from obd0 to obd1. obd0 is 88-91, obd1 is 92-95, obd2 is 96-up

 

I'll have to write that down haha.Are there any special letters for the 1.5,1.6,2.0 engines?

 

to be honest, i don't like b16. they are weak and no torque at all compare to the b18's. if ur going turbo, go Ls but, if u have the money go gsr. gsr turbo will be sick. my buddie has one, stock everything with the tubo setup t3/t4 boosting 6-8 psi and ran 12.4 on his 92 vx hatchback.

 

sohc are just baby motors lol. b16 are decent for boost but in my opinion there to small. ls(b18a1,b1) and great for boost. the most common really, there very boost friendly. lsv arent very reliable unless done 100% correct so boosting them would be even more unreliable. gsr imo is the best. 1.8 vtec motor with semi low cp pistons. b20 blocks have weak sleeves so there no good for boost. type r is a good motor but can only be run on low boost bc they already have 11.5 cp pistons

 

What about B18c1?What are their strong and weak points and are they good to boost?

 

i like my b16 on boost but i loved my friends 420whp lsv on boost. a mild b16 on boost is fun on the street( i have one) if you dont mind revving high to make power and having no torque. but a ls has better torque. and a sohc on a bunch of boost is really fun...small engine and torque almost equal to hp its little man syndrome at its best. no matter what welcome to your new addiction once you go boost you are on the dark side and youll never go back

Lol yea.I had a hard enough time driving slow after I hit 110mph on the highway...after that 40mph seemed slow enough to run.I can imagine how much fun and exhilarating a boosted civic would be.
