13.5 comp is it ok for a street car

[spoonfed]

hey guys just wanted to find out if this setup would be ok to drive on the street it want be a daily driver maybe once or twice a week and the odd trip to the drag strip its a build b20

the answer is simple. it all depends on how well it was tuned

you just give to me cause your a nice guy

[DLO01]

Ok? I think it would be awsome to drive on the street or anywhere for that matter.

Good parts, good install, good tune. Why wouldn it be? :D

[EGB18CT]

yes, just, there's e85 too :)

[DNYALL]

that would be insane to drive anywhere :thumbsup:

[Chr1s]

I wouldn't.

[spoonfed]

I wouldn't.
whys that

[Benson]

For that much work, build yourself a K24!

[rpm boy]

As long as the fuel u get is good and your tune is decent shouldn't be any troubles.... Shot of nos never went astray as all :p

[MikeyG]

with those parts and labour = BIG $$$$ ... you could get a k24a in your engine bay

[GSi_PSi]

If he already had most of the parts would it really cost more than a K swap?. The most expensive part are the sleeves and then installation. Who in australia does sleeving for B20?.

Properly not cause he can sell off his set-up off and add on top to do a K swap.

To the OP, i don't think you need that much compression to start with. Keep the combo simple and you would see better results :)

It all depends on the quality of your fuel, if you can get consistently good quality fuel and an equally good tune, you may be able to get away with it. Otherwise you will need to look into E85 or race fuel, and again availability and cost of fuel play a big part in this.

my wifes car runs 13.7 comp ratio and runs on E85, which is a bit of a pain due to the lack of E85 availability, but the car is not daily driven anymore :D

[dougie_504]

My opinion is that you don't need that kind of setup for a daily, but it's up to you mate. That's something I would only really consider for a weekend car etc but for me a daily is just A to B with maybe a little bit of fun (which is why I have the EH Civic VTi with I/H/E ----> still slow!).

From what I've heard the B20 bottom isn't that reliable, even with a lot of work done to it. Personally I'd consider a B18 bottom (if you don't have one already) with some aggressive head work, or even just the head work on it's own + bolt-ons.


Either way, best wishes to you with the build. Show us the monster! :)

From what the internet has told you :thumbsup:. The B20 is know for its sleeves to fail, which i have yet to witness or know of someone personally that has had it happen, Personally i rekon with a NA application the sleeves will be fine aslong has you havent overbored it. Forced Induction is a different story.... Futhermore your saying even with sleeving the B20 isnt reliable?. Please explain.
Why would he want to downgrade to a B18?

the price i pay for this build was dirt cheap and i consider doing the k24 but it work out it was going to cost me about 2k more the what this build did so im up happy with what i got and my car is only a weekend warrior anyway

Im not entirely sure you factor in if things will fail with the B20's. But yeh, I would of went for a K24 set-up for all that trouble and will make more power than a B20 would ever make

[Chr1s]

Benson makes a good point with K series.

13.5:1 is not needed. Where does this more compression is best crap come from?

I have an idea, how about you go find your ecu tuner and ask him what he thinks of that compression ratio, he will tell you on the spot what is safe and what makes best power. I hope you understand that the higher the compression ratio you run, the less timing you can achieve (on pump fuel this is an issue) - race cars overcome this by using race fuel and the likes (water injection, etc).

It is normal in common practice to chase less ignition timing with the same power although in above example it's at the expense of detonation

Edit: Don't get me wrong, i'm not driving you away from this build, i'd love to see it happen - I'm just putting my cards on the table.

[moo moo nel]

when I read the topic I was like.. is that a joke

[EGB18CT]

go a erl block k26/7 with 13.5cr with a nice flowing head and you will have one of the nicest k's in the land if you can afford it :)

[GSi_PSi]

i wanna see this 2.2 Litre B series :). Has the motor already been built?

[040501912]

by saving up 2k for not going for K series is a bit lame..

u have to use e85 or race fuels to keep it running and not having it PING PING PING on hot sunny day =p
that high compression is not recomended to be daily.... if you are hardcore enough DOO IT DOOO IT !!! lol

BUT hey, be different and have one of a kind b20 2.2!! why not!!
as long you are certain that you will have a reliable engine!

Good builder
Good tuner
Good fuel
sensible driver

it will last.... for awhile i reckon lol..

[honda_b_blastn]

Ben is looking at his options by purchasing in the states,which you all know is a good decision atm due to there economy and our dollar being very good currently.

Yes the engine has already been built/ran,he has a few options on his table.I have already voiced my opinion on the 13.5 comp on 98 octane to Ben.

His current setup is a Oem B20 bottom end,b18cr head,skunk intake manifold and TB,smsp header,apexi power fc-best 1/4 time of 13.6(dc2 chassis) i think Ben?? The engine was supposed to have Buddy club spec 3 cams,but Ben never recieved them after paying Dave Flood(join the club there),so we had to use his type r cams.

Here's his current setup while i was assembling the engine:

pump gas + water meth injection

hey yeah the motor is built im just waiting for my builder in the usa to send it should leave the usa tomorrow

well all up deliver to my door this engine package cost me $5200 im sorry but im yet to here of anyone do a full k swap for this sort of money all the pricing i have done i was looking at around 10k so i'm happy with what ive done and with how often i drive my car it should be right

[GSi_PSi]

wow motor is looking nice.

[honda_b_blastn]

wow motor is looking nice.

wait for the new one ;)

[delsol9000rpms]

more comp will always give more power no matter what.

Man that's an awesome idea, I'd never thought of doing that. The only thing that scares me is maybe getting the engine to my door and realising it doesn't have all those internals, but I doubt that'll happen.

Good buy :)

[Benson]

Im keen for some numbers if you decide to go ahead with the motor

Would be one of a kind in AUS

[MikeyG]

yes would be indeed.. engine is sexy.. headers looks yummy aswel good ground clearnce

I was wondering what do u mean by fail?. He's sleeved his block?. How is his setup less reliable than say a K24? , both got rod stroke Ratio of 1.54:1.. unless your talking about the compression ratio?..

[RandyRhydah]

i'm keeping an eye on this thread.. i have similar idea of high compression B20 build but without the stroker... im thinking i may run 12:1ish instead of 13.5 like i was planning to.. lol

thanks for a good thread guys

You should see what holds the crank in on a K series Sam, then you'll understand :p

[fatboyz39]

13:5 is ok for track/drag motor with extensive tuning and good fuel (Jungle juice E85).

[kraiye]

getting back to the OP... i dont understand the point of the question!
why do you need to ask if it would be ok to drive on the street?
as long as it's tuned well, is not too low, is not too loud and doesn't have some mofo clutch... don't see what the question has to do with engine parts! [/rant]
