I was going through all my CA crap to get an idea of what I have and what I need to get to complete the 2 liter engine. Well, I find I have an 18 block that has already been bored and honed. I also find a head with newer guides, already ported and decked! Man I have no brain, I forgot I had all this stuff left over from when I was going to build a motor for my Silvia. With all this work done already I can get some pistons to go along with the rods I have already polished, duh, and throw a motor together for now. I will be able to spend what cash I have on an EMS and pistons and be back on the road sooner. I am not abandoning the 2.0 project but now if I can get a running engine in the car I can save up and do the big engine right without pressure.Coolness!

Sweet... Good hear you'll be back sooner rather than later. Similar thing happened to me. Thought i had a rod knock, pulled the motor, took it off insurance figuring i would be out for the count till next summer, Met up with a fellow ca'er in my area, picked up a sweet little motor with a few goodies on it already, Had the car back on the road 6 days later. LOL

So it's going to be a CA20DET or did i read wrong? That should be a sweet little package.

I am getting parts together for a serious 2.0 and as such I was going to have a machine shop bill of about 2k by itself and have to send it up to mainland to get it done. I am still going to do that motor but now I can take my time to accumulate more parts and save up rather than go back into debt to get it done. The bits that I found are already ready to rock so I can slap a CA18 together now without breaking the bank and get savvy with the EMS I go with on the shoestring motor. When I finally do up the 2.0 I should be a more learned engine builder and tuner. I will retain the oem rotating assembly with this one, the 2.0 will be all aftermarket. I still expect 400 out of the 18.

LOL, I know! I know! The TMS owes me big for my little discovery. But until we're sure everything is savvy, we're not gonna let the cat out of the bag....

Are you telling me that The stroker crank pictured is not from tomei but from another Nissan engine. I will pay one of you guys to tell what motor that is from. You're secret will be safe with me.

Tomei crank Bah! that thing is nothing but a stock CA20 crank with a big snout. This was Ryan's idea, I am just testing it. When it is done, with his blessing, I will explain what I am doing.I will share one little tidbit, unrelated to this. The RB pulley will slide onto a CA crank. Why is this important you may ask. CA18 and 20 cranks are half counterweighted so more suceptable to vibration. ATI makes a damper for the RB,,,,,,wait for it,,,,,,see where I am going? I will be looking into converting to an RB pulley so I can figure out what it takes to work so those that choose to get the RB vibration damper can upgrade their engines without having to figure it out themselves. So far I know it slides over and it sits too far down the snout so will need a spacer and the pulley is a different diameter so stock belts are the wrong size.

Oh i get it now. So what your going to do is take the crank from a b16 and fully reschematicize it to work with an rb crank pulley on the ca18 block. Well you don't call yourself the the Mad scientist for nothing. I have one question when vtec kicks in will i be in control only because i can loose control or does it not work that way. I'm slightly confused on what badges i should have installed on my car after this mod. Can i get a type R and GTR badge installed after this. If so it seems like the only safe and reliable way for both to be installed at once... of course ill get all of the accompanying mods.

It's not a Honda crank and variable timing is for geeks. I like a lumpy idle myself If it works out the way I think it's going to it will have at least three different car manufacturer's parts in it and an extensive list of very specific parts. That's why I won't detail it until it is done, running and tuned out, it's so freaky. It will either be awesome or it will self destruct on the first full throttle run. ****ing Ryan started this, I blame him.

I am going to slap a CA18DET together with a Haltech for the short term to get the car back on the street while continuing the work on this critter. When done you can expect an extensive writeup on what to do. There will be several variations, I am looking at all of them which takes time.

just out of curiosity, how big is your garage?! i mean, ive got quite a large garage but I dont think I could miss an entire short block regardless of how cleverly disguised it was.

Oh cool, so Ryan you going to throw that 4 port on this thing too???? I will source another motor just for this project as I have a block already dedicated to the NA CARB setup.

Hey R34 gtr if you saw his "carport " you would easily understand how this man could misplace a whole damn motor

At least he has a place to store his stuff though. My garage is still sitting in the bank waiting for this damn architect to get off his ***.

i'm not sure how good of an idea it would be to use a dampener from another engine. as far as i know high end dampeners are tailor made for particular resonant frequencies in specific motors so i'd think that it's just a plain bad idea to use the RB dampener on the CA.

It's hard to explain exactly how a harmonic damper works without pictures and slides from my physics 212 class but in short dampers work by isolating a weight within an elastomer web. As vibration travels through the crankshaft, the elastomer delays oscillation of the weight long enough to get out-of-phase movement. This effectively cancels all vibrations seen at any rpm. So the good harmonic dampers will be able to dampen any resonance created. As long as the thing is mounted correctly on the crankshaft there would be no problem at all.
