B16a To A B18c ? [Archive]

b16a man

28-12-2006, 01:56 PM

I currently have a b16a engine in my crx if i wanted to fit a b18c style engine would it be a straight swap over or would i have to change the b16a engine mounts?

also what type of b18c engines are there and what would be my best $ to kw ratio if i was to go with that option.

The reasopn i am asking this is because i am not sure if i should mod the b16a as i dont know what will give me my best gain in the end.

Or would a turbo be the best for this engine.

Any ideas would be great

Regards John

best kw for the dollar is turbo..

yeahh turboing the b16 would make more power then going b18cR...
but if u did wana do a quick, cheap upgrade, just get a b18c bottom end and put that in...

How much would a turbo setup cost ?

Would this affect my setup if it is a daily driving car

well that depends on if u build your own or buy a kit, and on stock internals i wouldnt run more then 7psi... if its your daily driver, you want it doen properly so its reliable....
all depends on how many ks ur motor has done etc

b16a man

28-12-2006, 02:07 PM

the motor has only done 75,000kms

would $10,000 be enough for turbo setup to make a 13sec car?

10,000 is enough to boost you car nice and safe, while running enough to get easy 13's.

yeahh i rekon you could hit 12's in a boosted b16a in a CRX lol if done correctly, with suspension and slicks and wieght reduction...

My setup has so far been under 10k and i managed a 13.9 on cheap street 14s on 6psi

answer to your first question is
no u dont need to change anything just take out the engine and put the new 1 in.
and for bang for bucks turbo. on stock internals like most people say 6-7 psi if u want more power u can take it up to 10psi but you'll be in the danger zone with stock internals
and yes 10K is more than enuff to get u running into 13's easy your more likely looking into 12's with slicks and so forth liike others mentioned

If you going to put a B18 in might as well use the head off your B16 and do a B20 conversion:)

My cousin and uncle both have crx's with b18 type r/b20 frankenstein set ups. First time at the drags, one did high 13's and the other did 13 flat. The one that did 13 flat wasn't lightened yet, and the uncle who was driving the white crx didn't know how to launch properly.

Having said that as my cousin built both the motors - obviously it was money saved in labour. but just consider your options :)

a properly sized turbo on stock internals can run 10 psi without a problem, assuming you have a proper engine management set up that has been tuned. Most kits DO NOT come with a proper engine management set up. You're looking at something like hondata and larger injectors at the very least.

6-7 psi without proper engine management is FAR more dangerous and hazardous to the motor than 10 psi properly tuned.

It's ALL in the tuning. Bad tuning and the motor can blow with hardly any boost. Good tuning and it can run good amounts of boost with perfect reliability.

Remember, the engine management is the KEY to a good turbo set up and is THE MOST IMPORTANT part. EVERYTHING else is secondary. The turbo, the manifold, the intercooler, etc... all secondary. Engine management is number one, and the absolute last place to cut corners. You need a fully programmable ecu and larger injectors to run well. Don't buy into the idea that an fmu or a vafc will work for you, etc... they don't.

so to do a b16a2 to b18c converstion, all u have to do is take out the old motor and put in the new one? what about the ecu would u have to use the b18c ecu? and the loom? everything from the b16 loom will plug right back into place on the b18c?

You need to match the ECU to the engine. B18c have IAB so you will have to add a few wires.

It's ALL in the tuning.

Quoted for truth.

This stock b16b runs 9psi (max), despite higher comp than b16a, using 510cc injectors.

bserseise wiring hraness is the same only diff is the change of the ECU

keep the b16a man.. i believe it has more potential than the b18c.. and yeah just go turbo bang for buck cant go wrong..

IMO Bigger the better!!

locote

Maybe the B16a has more potential cause you can buy 2 of them for the price of one B18c???
thats 240kw compared to 136kw hey??

];1021120']IMO Bigger the better!!

thats so true
if the b16a has soo much potiential then why is it that both engines with the same mods, the b18c always produces more power
even with a "bang for buck" bolt on turbo kit the b18 will produce more power

b16a is the fkn stupidest and shitest motors in the worlld

i would never go back to one ever again.

u have to rev the farker and waste petrol just to overtake something.... wat a pos.

when i change from b16a to b18 in my sol it was the best thing that i ever did for the car

locote

01-01-2007, 06:01 PM

Amen to that...
Ive had B16a powered civics wanna give me runs on the freeway, they go for a lower gear i stay in 5th and still pull away theres just no comparison.
Its torque that makes you move and the B16a lacks it...

Leave the 16 in there and just rip out your interior and everything else you dont need.. Power to weight. Wont cost you anything then.

not everyone wants to drive with a stripped interior
its not only loud, but might also attract unwanted attention

thebob

Wont having a giant intercooler hanging out the front attract the same amount of attention but for 10 fold the price.

where df did u get an intercooler from doofus. :rolleyes:

if u swap a b16a with a b18c.

i guarantee you wont even know that it has been swap.....

locote

02-01-2007, 06:54 PM

LOL...
Theres some thing called black paint, intercooler is a radiator paint it black and you wont even see it..
thebob ur a funny bugger!!!
The only time i get attention is when my gate opens, apart from that it looks like a stock standard civic with a loud exhaust.

thebob

02-01-2007, 06:59 PM

Ok i will take the paint it black approach... Paint your windows black so you cant see in thus no attention because you cant see its stripped. Grand total $3.

locote

02-01-2007, 07:03 PM

WTF striped interior for everyday driving is the stupidist thing to do!!!
Why would any one do it to get to and fro work???
I can understand at the track..
It is totaly different to spraying your intercooler black!!!!
Why are you even comparing both???
Its not only stupid but highly dangerous and illegal..
LOL at thebob for that coment

If everyone was as serious as you we wouldnt have comedy.

It was a figure of speech mate, paint over your problem.

for a moment i thought u were been serious

the thing b16 lack is torque.. it already has enough raw power.
If you are already ligth the torque factor plays a smaller part..

however there is no replacement for displacement

BTW is a str8 swap.. even you oringal ECU will run.. just not optimal

Just factor in..
new clutch, new timing belt, water pump, oil, oil filter,headers if yours dont fit and ecu converiosn harness

if you want to get it done i also know someone who can do it at a good price..

pm me if interested

wow didnt know that this thread would cause so much controversy.

Hehe but there has been alot of good pointers.

so many decisions to make, i guess that i dont want the fastest car in the world so maybe a turbo kit will give me the best value for money.plus alot of added power.

and also the look i would be happy to beat skylines and wrx,s with a turbo b16a.

thanks heaps for the info people i appreciate it :)
