I'm 50/50 on throwing a regular civic engine in my car and selling it. But I have a ?, what would you guys do if you had the chance to rebuild a block (Sleeve need to be replace regardless, also rods and pistons):

Rebuild it to stock

Rebuild it to accept boost

Rebuild for high compression

I just want to see some opinions.

Keep in mind this will be in a 93 SI hatchback. I already have a brand new ITR head ready to go on whatever I decide (Even if its selling it seperate).

Need opinions and suggestions guys.

Ya@inlinePRO

maybe i missed it? but what block? you have?

Apex i ITR

Oops sorry I assumed everyone remember'd what happened to me a few months ago. I have (Had) a JDM ITR motor. Had some Toda stuff in there and dropped a valve. Ripped up the head (Which is why I have a brand new head) and cracked the sleeve on the block in 2 places on the same cylinder, put a dent in the same cylinder's piston and twisted a rod.

Which is why I'm askingthis ?

Dr. EKology

if i were you...i would easily turn that car into an all motor monster!! b18c5 is a great motor for the eg, and since you already have a head and a block on the way there isnt much of a decision to make (imo). For sure put together the motor, but the decision of boosting or all motor has to be made first so you know how high/low to make your compression. Good luck either way!!

all motor

Eyewitness

ALL MOTER...the C5 is already high comp...so turboing would be my least favorable choice...

Apex i ITR

That's what this post was about. What would you guys do in my situation? I have to replace all the internals anyway of the block so really its only a B18C(R) by block stamping right now.

I went all motor kinda (Not all the way). I had Spec B's, springs, retainers, JDM DC header, AEM CAI etc. I got about 186 to wheels, I think there would have been more with higher compression and bigger injectors.

If I go all motor again I'd put @ least CTR pistons w/thinner head gasket (or maybe JE's). I want compression @ least 12.1:1, Spec C's, and everything I'd need to make it run.

If I go forced induction I'd put 9.5:1 or 9:1 compression pistons, get it sleeved and get a drag kit and run about 9-12 lbs of boost with bigger injectors and everything else needed (With a Hondata stage 3b).

owen_the_soyboy

an ITR block in need of work?

I would go as big as possible in displacement, cant you go near 2.0 liters with that setup?
thats my 2 cents

vtecvoodoo

I`d go 84mm.

I`d run at least 10:1 w/ some type of forced induction since your car is still on the heavy side a bit. Or run 11:1 at 84mm which would make good power and throw a hundred shot on for ***** in giggles. It can handle it easily. I`m not really an "all motor" kinda guy, but at 84mm and 12:1 NA it could be fun, too.

All in all, it really depends on what you want to do w/ the car.

Yup, build it for NA purposes. That's what the B18C5 was made for.

Apex i ITR

For those of you that said the ITR is high enough compression already, I realize that but I have to replace all my internals anyway so I can go either way right way. Right now my block is basically a shell with only things salvagable being the crank, crank pully and the sensors.

Vtec Voodoo I was thinking if I go FI I could run 9.5:1 compression get it sleeved and run about 8 pounds of boost dailey and 12-13 pounds when I really mean it. How much boost would I be able to technically run on 9.5:1 compression with sleeves (From import builders) and a Hondata stage 3b with a good tuner.

I'm not sure what I want to do with this car. I'm @ the point now where I'll never see what I've got in it right now. I wanted to buy another vehicle next year that was turbo'd from the factory (WRX, EVO, RX-7, Supra or build a SR20). I'm kinda caught between do I really want to mess with a new car note (EVO, WRX), potential reliabilty problems (RX-7) too high of cost of ownership (Supra) or the headaches of another hybrid (SR20).

Believe it or not my cheapest option to go faster right now is to build the current car I have and make it faster (Timing is all wrong though).

I would just drive it but because i have to fix so much stuff it makes sense to build it now instead of just slapping everything back together.

You can easily handle 12-13lbs at 9.5:1. Just needs to be tuned right. Jeff@IB can get it dialed in. Ask "supergreensol". Jeff just built the same setup for him.

Wifey is a fan of staying stock. Less of a chance of something else going wrong (She pointed out that I don't have the best of luck when it coems to cars). She also thru something in face that I told her once. Why try to turbo something that didn't come that way fro mthe factory........she does have a point.

I'll sleep on it but most logical step is to keep it N/A

vtecvoodoo

...but all motor 12:1 won`t be trouble free either.

Eyewitness

You wont have any trouble with 12:1 ...the JDM ITR has 11.6:1 STOCK....PLEASE

Apex i ITR

Wouldn't there be less of a chance of a problem going all motor.

And actually all I'd do is some CTR pistons with a 2 layer head gasket. Probably would be around 11.7-9:1 cr. I could live with that.

vtecvoodoo

ok, you don`t think he`ll have a single problem and it will be 100% trouble free? Wake-up, it`s a frickin HYBRID!

CTR pistons, you are just going to hone the block now and run 81.25?





[Modified by vtecvoodoo, 6:52 PM 7/9/2002]

Apex i ITR

That is so true. I have had nothing but problems come up (Kinda scares me away from doing a Sr20 swap).

Anyway I'm thinking if I run CTR pistons and Honda rods then I should as close to Honda reliability as you can get but higher compression so when I do decide to do cams again I have compression that higher lift/duration cam ready. Or leave it alone and try do something else.

Apex i ITR

Would i need to hone the block if I'm getting resleeved?


Maybe go slightly oversized. I'd rather not if I don't have to.

vtecvoodoo

Makes sense. Like I said, it really depends on what you want to do w/ the car. I prefer to do everything the 1st time around because I know I`d regret not going 2.0 down the road. This is why my motor has been under the knife for 3 months . No other all motor power adder will makes as big of a difference as being 2.0 versus 1.8 IMO. Again, it`s your choice, I`m sure you`ll do the homework and come up w/ right solution to fit your needs.

vtecvoodoo

Findout how bad your cylinder walls are 1st. You probably don`t even need sleeves. Bore n Hone + oversize ctr pistons should do the trick.

Apex i ITR

They looked like pretty good sized cracks in on top of the cylinder walls. Do you think they can still be salvaged?

vtecvoodoo

oh cracked, thought you said scarred. You need sleeves. I`ll let Jeff talk you into going 2.0, my fingers and wrists hurt

Apex i ITR

Thanks. You're the only person that has responded anyway. I'll tal kto Jeff when he is open in a hour.

supergreenNA1

if the cracks go all the way thru the stock sleeves into the casting you'll have to have the block resleeved. once you sleeve it, you instantly have a block that will handle as much boost as the big boys. so why not go turbo? since the advent of hondata, it is 100% possible to have a street driven turbo car that is reliable... just as reliable as an engine built for all motor. reliability becomes a factor when you build the engine... not when you go turbo. and regarding the b18c5 being for all motor only... bs.. lower the compression to 9.5-10.0 and you'll have one of the best turbo engines around.
